2023 Chevrolet Tahoe complaints

Transmission has had a failure to shift problem on several occasions resulting in deceleration and a decreased ability to accelerate. This has occurred on most occasions at highway speeds while passing a vehicle causing a very unsafe condition. Dealer has evaluated and determined the transmission valve body is defective and needs replaced. Upon researching the problem, many similar GM vehicles are experiencing the same issue

The car has cut off three time while at stoplights. I can get it restarted but the dealership cannot duplicate it even though there are codes in the system. Also the automatic braking will randomly stop when it shouldn’t and it is a hard braking.

The engine randomly shut off while driving down the interstate and wouldn’t start back up. The car had the recall “remedy” done to it. Inspection and thicker oil. The only warning I got was to restart the engine after it shut off. My safety was compromised by breaking down on a main interstate coming through Memphis with no emergency lane to pull over in.

2023 Tahoe Z71 had recently been put in the shop, and evaluated for engine failure recall. Dealership/GM deemed it failed test for replacement, we were given 0W40 oil and sent back out, this last weekend we had catastrophic engine failure while operating at 50+MPH.

On April 10th, while traveling approximately 7 hours from home on a very busy highway in [XXX] , my 2023 Chevrolet Tahoe (6.2L engine) suffered a complete and catastrophic engine failure, requiring a full engine replacement. The vehicle had to be towed and I was left stranded with no transportation. Prior to this failure, I had brought the vehicle to an authorized GM dealership for a recall inspection specifically related to the 6.2L engine on September 9, 2025 with 36,162 miles. The dealership technician inspected the vehicle and informed me that my engine was not defective and cleared it. Shortly after that inspection, the engine suffered a total failure at 46,6xx miles on the vehicle. I am currently leasing this vehicle at approximately $1,100 per month and have been without the vehicle for an extended period while it sits awaiting repair. GM customer care has been contracted and has indicated they cannot move forward with a buyback claim because the BBB is not taking my case because the vehicle is older then 2 years old which I know is a false legal claim. This is a serious safety concern, a catastrophic engine failure at highway speed poses significant risk to vehicle occupants and others on the road which appears consistent with other reported failures. I am aware that NHTSA has opened Recall Query RQ26001 investigating the adequacy of GM's remedy under recall 25V-274. My experience is consistent with the 36+ complaints that triggered this investigation, engine failure

As I was driving down the tollway in Dallas going 75 miles an hour, my engine completely shut down and went into neutral in rush hour traffic. I had to slowly get over from being in the left lane as my car was slowing and slowing. I was able to get over on the side of the tollway as cars zoomed past me. By the grace of God, I didn't get hit. Once it was towed, the service department confirmed that it is my engine that shut down and the entire engine needs to be replaced. Now the problem is they cannot find an engine or parts to fix it. No warning came on at all before this happened. Very dangerous situation.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The oil was changed at the local dealer. After 24 hours, the engine was blown after driving approximately 50 miles. No warning lights were illuminated. While accelerating from a stoplight, there was an abnormal squealing noise from the drivebelt. The vehicle was taken back to the local dealer, and the contact was informed that the flywheel was hitting the camshaft and changing the oil had disturbed the function of the vehicle. The vehicle was not fully diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 14,945.

We were driving down the highway at around 77 miles per hour. I noticed that the vehicle chimed as though I initially got into it and needed to start the engine. I saw the dashboard asking me to start the engine. I attempted to start it while we were coasting to a stop, but it wouldn't start. I was able to barely get out of the lane of travel and avoid a collision. I tried to turn off the vehicle and turn it back on but it would not start. It would not even turn over. The vehicle eventually cannibalized the battery because it would never shut off.

At less than 50,000 miles, my alternator went out and had to be replaced, causing the battery to need to be replaced also. Now, at only 51,000 miles, my transmission is having problems and causing the vehicle to jerk when shifting. This vehicle has had regular maintenance performed by a combination of dealers and certified service centers since it was purchased brand new. I have never had this much trouble with a vehicle and am very concerned about it's overall safety and integrity, given the severity of the problems for something that is not old and does not have high mileage.

Passed a truck in 2023 Chevy Tahoe on a two lane highway and the Tahoe would not accelerate. It switched into neutral and would not run. This was a major safety issue. There was a semi truck behind me that could have run over me and my family. Luckily there was wide open area next to the road that I coast into. Truck was towed to a dealership out of state while we were on vacation.

My wife just picked up our 4 year old from daycare. She just merged onto I-81N and the vehicle shut off on her at highway speed during rush hour! A message on the dashboard said "Please restart vehicle". She managed to pull the Tahoe off onto the shoulder, but couldn't get it started. She remained in the vehicle with my daughter and called 911 to request a state police vehicle park behind her so that she wouldn't be hit by any passing traffic. I (her husband) met her on the side of the highway and we tried starting it with a battery booster pack to no avail. We called a tow truck and had the car towed to the dealership that we purchased the vehicle from. They confirmed that the motor was indeed locked up and needs to be replaced. This vehicle already underwent the 6.2L recall test and "PASSED". It was running the 'remedy' 0W-40 oil. This is COMPLETELY UNACCEPTABLE.

Engine failure resulting in new engine.

1) The engine failed and lost propulsion while driving. It is currently at the dealership where I purchased the vehicle new, so it may be available for inspection upon request. 2) My safety was put at risk because the vehicle lost propulsion while driving. This is a dangerous situation in general. In my case I was able to pull over safely and have it towed to the dealership. 3) The problem is that the engine failed. This can be confirmed by the dealership. 4) This 6.2L engine was part of the N252494001 recall for specifically the issue of engine failure and loss of propulsion, so it had been inspected by the dealership recently. I brought the vehicle into the dealership for this recall several months ago. Per the recall, they told me that the engine would need to be replaced if it didn't pass the inspection. They performed a Pico test, informed me that it passed the test, and changed the oil to 0W-40. It has not been inspected by GM, the police, insurance representatives or others at this time. 5) There were no warning lamps, messages or other symptoms of the problem prior to the failure.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that while driving 50 MPH, the transmission unexpectedly downshifted before the engine seized. The check engine warning light was illuminated, and the reverse(R) indicator was flashing. The contact was unable to restart the vehicle. The semi-truck behind the vehicle almost crashed into the rear of the vehicle. After several minutes, the contact was able to restart the vehicle; however, the failure reoccurred. The check engine warning light illuminated, and the reverse(R) indicator light was flashing. The contact was able to restart the vehicle and pulled over to the side of the road. The vehicle failed to accelerate 5 MPH. The contact drove back to the residence slowly. The contact arrived at the residence, and the vehicle failed to shift into reverse(R). The vehicle was towed to the dealer. The vehicle remained at the dealer unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 70,000.

Total Engine Failure

The vehicle motor goes out with no indication that anything’s going to happen. It does this a different stages of miles. Mine happened when I was passing someone on the high way. It just shut off

Our vehicle passed their inspection required test for the engine recall and then at an intersection just died with absolutely no warning and wouldn’t even start again. Warning light for low engine oil came on. We were stuck and couldn’t even put the vehicle in neutral to be towed out of the intersection. Had to call a flat bed tow truck to load it and take to dealership where it was confirmed the engine failed!!! Police did show up at the scene to facilitate traffic and the loading of th vehicle

The contact owns a 2023 Chevrolet Tahoe. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling) in November 2025 by the local dealer. The contact stated that the engine had passed the inspection, and a higher viscosity oil had been added along with the other steps stated in the recall. The contact stated that while driving approximately 55 MPH, the accelerator pedal was depressed; however, the vehicle failed to respond. The gear shift indicator indicated that the transmission had been shifted into neutral(N). The contact attempted to shift to drive(D) when the vehicle stalled. The vehicle was stopped but was unable to restart the vehicle. The vehicle was towed to the same dealer who had completed the recall repair. The dealer diagnosed the vehicle and determined that the engine, starter, radiator, and fuse block needed to be replaced. The vehicle was being repaired. The manufacturer was informed of the failure and a complaint was filed. The failure mileage was approximately 48,000.

My 2023 Chevrolet Tahoe LS has experienced repeated service issues within the first year of ownership. The vehicle has been in the repair shop five separate times and out of service for approximately five months total. Due to extended repair periods, the mileage remains extremely low. A primary concern involved the steering system. The steering wheel was noticeably off-center while driving straight, requiring continuous correction to maintain proper lane position. Steering-related components were inspected and replaced. There were no warning lights present at the time. However, improper steering alignment raised safety concerns regarding vehicle tracking and stability. The vehicle has been inspected and repaired by authorized service providers. I am submitting this complaint to determine whether this reflects a broader safety-related issue with this model year.

I took my 2023 Chevy Tahoe in for all recall corrections promptly when the notices were received. My last recall was to run a check to see if my motor was one of the defective 6.2L engines. It was determined it was not and the dealer changed my oil to the new required 0w-40w. Now a month later as I am accelerating on to the freeway ,I am at 65 MPH I cross traffic to merge on to a connector bridge and my car RPM's go through the roof and the car starts to slowly lose power. Zero warning lights are on at this point just decreasing power. As I am on the bridge my engine light comes on with a engine oil hot idle engine notice I am now at 35 MPH. Then a oil pressure low turn vehicle off notice comes up and we are at 15 MPH the car turns off. The screen says press start again but as we do it wont do anything. It then randomly starts turning off and on. We got to a point on the bridge where we could coast to the connecting freeway below and pull over. My car was towed to the dealer where it has been confirmed it needs a new motor with no know ETA of the new motor.

Since 15,394 miles vehicle has experience multiple system failures upon vehicle startup. 2/24, 2/25, 12/25, 1/26. In all of these 4 instances the brakes become spongy/hard, steering wheel locks, and I am not able to control vehicle. Dash lights up; "Brake system failure - 43mph top speed", "Fwd collision system unavailable", "Service traction control", "Service ESC", "Service steering column lock", "Service brake pad monitor". Dealership has replaced, Telematic control module, Electronic brake control module (EBCM), Serial data gateway module, Park assist module and most recently they replaced the battery and cleared the codes to "fix" the same intermittent but recurring condition. In 11/24 Recall N242447990 was performed, reprogramming of Brake system control module and Serial Data Gateway Module, the exact same issue happened before and after the recall.

To NHTSA, I am reporting a serious safety defect in my 2023 Chevrolet Tahoe purchased from Criswell Chevrolet (Gaithersburg, MD). Defects include a documented brake system failure while driving and repeated electrical/shift faults preventing shifting out of Park. The issue is ongoing even after the dealer/manufacturer stated it was fixed. Key events: Feb 3, ~12:45 pm: While traveling ~35–39 mph on a five‑lane road, brakes failed. I slowed by coasting uphill and using maximum pedal force to ~5–7 mph before stopping. I have video of the incident and two other times this has happened with pictures as the car was in park. Three prior start-up incidents: All dash lights illuminated (including brake failure and Forward Collison System Unavailable); vehicle stuck in Park. First required towing; dealer could not replicate despite reported stored codes. Subsequent event stranded my family. I have notified Chevrolet and the dealer; their offer does not address safety or recurrence. Please record this complaint, assess broader risk, and advise on related recalls/investigations. If there is a path forward to ensure the safety of my family, please respond with that guidance. My phone number is [XXX] .

I purchased a 2023 Chevy Tahoe in Oct 2025. Since then, I have been trying to figure out how to set up the myChevrolet app. The OnStar button doesn’t work so I called OnStar. After multiple calls, they told me that the account is linked to the previous owner and can’t be transferred because of a faulty telematics communications module. The faulty module is also causing the clock to run slow, which indicates battery drain is beginning. The OnStar module failure poses a huge safety and privacy risk. Safety concerns include battery failure that can cause me to be stranded and the fact that the previous owner has the ability to start my vehicle at any time, even while parked in my garage posing a risk to my family’s health/life with trapped carbon monoxide building up. Privacy concerns include the previous owners ability to track my vehicle, lock and unlock doors, access my contacts, call log, location, and more. This is a significant risk. The dealership should not have sold me a vehicle with a defective module without repairing it and now refuse to fix it. This should have been included in GMs factory recall for 2023 Tahoe TCU’s or a new recall should be issued. Consumers should not bear the burden to fix a widely known safety, health, and privacy risk.

When I started my car at home, all of the dash warning lights came on, one after another. I put the car in reverse and started backing out of my driveway. I tried to stop but there were NO BRAKES! I slowly pulled back into my driveway and turned the car off. I had to take off work that day because I didn't dare to drive the car. The next day I started the car up and the check engine light was on. Luckily, I had brakes and I could go to work. Now, a day later, my engine light is not on. I made an appointment at the dealership. They can't get me in until mid February so I'm stuck with this problem, not knowing if the brakes are going to fail while driving. Oddly enough, when talking to a co-worker who has a 2023 Chevrolet Suburban, she recently had the same exact problem with her car. She has an appointment scheduled as well. I also read a complaint on this website that had identical problems. This car only has 8500 miles on it. It's still new! Someone is going to be killed or hurt very badly if this ever happens while driving. Please look into this.

The following notifications showed up on my dashboard as my breaks failed me! I was going down a hill and hit the breaks and they would not work, I could NOT stop the car! - service break pads - forward collision system unavailable - break system failure - service traction control - service esc - check engine light on This is the SECOND time this has happened in 4 weeks. We just got it back from getting it “fixed” one month ago. One of the scariest experiences, losing breaks!

I am submitting this complaint to report a potential vehicle safety defect involving the factory-installed running boards on a 2023 Chevrolet Tahoe. The running boards become extremely slippery during light snow or minimal winter precipitation, creating a significant risk of slipping while entering or exiting the vehicle. This occurs during normal use and does not require heavy snow or ice. I have experienced multiple near-falls despite stepping carefully, and the condition is repeatable. Given that the Chevrolet Tahoe is commonly used as a family vehicle and may be accessed by children, elderly individuals, or passengers with limited mobility, I am concerned that the running boards present an unreasonable slip hazard under common winter driving conditions. At this time, no injury has occurred; however, the frequency and severity of the slipping raises concern for potential injury if the issue is not addressed. The running boards are factory-installed and have not been modified. I am requesting that NHTSA review this issue to determine whether the design or materials of the factory running boards meet reasonable safety standards for normal winter conditions. Thank you for your attention to this matter. Sincerely, [XXX] Vehicle: 2023 Chevrolet Tahoe Component: Exterior – Running Boards INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle was around empty with 40miles remaining and would not start via keyless remote. Upon starting the vehicle all lights on the dashboard came on, this has happened previously and it fixed itself. When this happens, I have 0 brakes. Forward Collision unavailable, Service Brake Pads monitor, Service Traction Control, Service Steering Column, but most importantly Brake System Failure

As the owner of a 2023 Chevrolet Tahoe, I am currently experiencing persistent issues with the instrument cluster going dark and a severely malfunctioning GM 6.2L L87 engine. In November of the previous year, I encountered a sudden and alarming loss of engine power while traveling on a multilane highway at a speed of 70 mph. I successfully maneuvered the vehicle to a narrow shoulder, where I remained, accompanied by a Highway Patrol officer, for over three hours until a tow truck arrived. The GM certified dealership informed me that the engine was seized. The mechanics were unable to start or manually turn the engine. Upon removal of the engine’s oil pan, they found metal fragments in the oil. After having undergone an engine recall “fix” three months earlier, which included an inspection and oil service change to a more viscous 0W - 40, a new oil filter, and a new filler cap; in November, my engine failed and was replaced with a new 6.2L L87 engine. Initially, I was pleased with the repair, but I have since lost confidence that my car is safe after the new engine began exhibiting symptoms of a pending failure. The Tahoe hesitates on acceleration when merging with highway traffic, the engine dies when decelerating, the check engine light flashes at highway speeds, and the instrument cluster turns off at random. The vehicle that has been outfitted with a brand new engine is currently at the Chevrolet dealership; however, just like in August of 2025 during the Recall inspection

My 23 Chevy Tahoe was diagnosed with catastrophic engine failure on 04/02/2025, and per recall N252494000 a case for engine replacement. That replacement was completed and the case was closed on 06/02/2025. Since that time the new, replacement engine has been consuming oil at a high rate, is running with intermittent lag and I am waiting for a diagnostics appt with Chevy.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that after the vehicle was serviced at the local dealer, the message "Add Oil" was displayed, and the vehicle continued to experience excessive oil consumption. The cause of the failure was not yet determined. No further information was available. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 18,000.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that while her husband was driving at 70 MPH, the vehicle experienced a loss of automotive power. The check engine and "Oil Pressure Low" warning lights illuminated, and the vehicle unintendedly decelerated. The contact stated that while driving at various speeds, the message "Press START Button" was displayed, and restarting the vehicle temporarily fixed the issue. The contact stated that after further inspection, the contact became aware that the vehicle had independently shifted from neutral(N) to park(P). The vehicle was towed to a local dealer, where it was diagnosed; however, no cause for the failure was determined. The local dealer advised the contact that the oil level was possibly low, and an oil consumption test was needed. The vehicle was not repaired. Upon further investigation, the contact related the failure to NHTSA Campaign: 25V274000 (Engine and Engine Cooling); however, the VIN was no longer included in the recall. The manufacturer was made aware of the failure. The failure mileage was approximately 33,253.

I purchased a 2023 Chevrolet Tahoe on December 17, 2025. On January 17, 2026, with approximately 17,000 miles, the vehicle experienced a catastrophic engine failure while I was driving. The engine seized without warning, causing a complete loss of power and leaving me stranded on the side of the road. At the time of the incident, my newborn child was in the vehicle, creating a serious safety risk. The vehicle had no prior warning lights or indicators before the failure. After the incident, I learned that there was a known recall or service update related to engine oil viscosity for this model year. This information was never disclosed to me at the time of purchase, and no recall documentation or corrective service was provided prior to delivery. I have since been informed that engine replacement will take over 30 days due to parts availability and that no loaner or rental vehicle is available during repairs. Given the catastrophic failure shortly after purchase, the undisclosed recall, extended repair time, and safety implications, I no longer feel the vehicle is safe or reliable.

Truck bucked twice in high-speed lane of the highway, gas pedal went soft and we luckily were able to coast the truck to the side of the highway without getting hit. The truck put itself in neutral when we lost the engine and the truck would not restart. It had to be towed, while me and my two kids stood on the side of a dangerous highway for 45 minutes in the snow. The truck has 52,000 miles, Engine was already replaced at 10,000 miles. It just passed the recall inspection and had the upgraded oil that was recommended.

For the third time, my windshield wipers quit working in the middle of a rain/snow storm. Have taken the vehicle into GM service under warranty twice, the first time they updated the software but that repair only lasted a few months. Second time they replaced the windshield sensor, that lasted a few months. Now today, driving home in the snow my wipers quit working altogether. The sprayer worked, the rear wiper on the same handle works, but nothing else I could do gets the wipers to work. This is a big safety concern as it has happened all while driving in I climate weather.

On December 30, 2025, I was driving the Tahoe at a highway speed in Oklahoma City, Oklahoma. I experienced two engine shut-offs. I was able to get the Tahoe to the Chevrolet dealer in Midwest City, OK. Advisor Tim took care of the vehicle and said that they "couldn't replicate the problem." He did mention he had to add engine oil because it was a quart low. We noted that we are currently conducting an oil consumption test with a Chevrolet dealer in Elk Grove, Illinois. He said we had a strong case for it, but the Tahoe was safe for traveling back home to Illinois. The following days, the Tahoe performed well without any issues. On January 3, 2026, we left Spencer, OK, and headed back home to Illinois. Without any warning, while driving at highway speed, the engine shut off completely and would not restart. The failure occurred at approximately 9:00 pm on a pitch-black expressway about 40 miles from Rolla, Missouri. I was traveling with my wife and two children. We were stranded on the highway shoulder. A state trooper was dispatched for safety. The Tahoe required a tow over an hour later, and we had to take a Lyft to a hotel. Logistics at that time in that location were complicated. Our family was terrified for our safety. Today is Sunday, and the nearest dealer is closed. We will have it dropped off tomorrow, January 5th, and go from there. We do not know how we are going to get back to Illinois. We have work and my son has school. The vehicle is currently disabled and under

I asked the dealer for information about the L87 6.2L engine rod bearing failure recall. I was told that they wouldnt perform the work until i recieved a letter from GM. This was when i got my first oil change. Then every oil change after that i asked the same question. At 43401 miles i parked the vehicle and havent driven it since. I am afraid to have something happen to me or my family. I paid $82,000.00 for a vehicle that GM's fix is to add thicker oil. I think that the rods and bearings should at least be visually inspected. The dealers maintenance manager at Kunes Lake Geneva says theyll listen to it with a stethescope. If it sounds ok theyll change the oil. I paid way to much to chance my familys safety on thicker oil. To make the situation better the vehicle blue books for $56,000.00 IT DEPRECIATED $26000.00 IN TWO YEARS. That is unacceptable.

The car was parked totally normal, went into a store, then came out to start it and when it was put in drive every light on the dash came on and gave a warning for “brake system failure top speed 43 mph” “service traction control” “service esc” “service steering column lock” “service brake pad monitor” “trailer brakes disabled service required”. Shut the vehicle off and restarted with same results. Brakes were inoperable and almost hit the car parked in front of me. Let the car shut down for a couple hours came back and started it and now everything acts normal except there is a Check engine light. Haven’t read the codes yet but am making an appointment at the dealer for warranty work.

While Driving to my appointments via the freeway, all of a sudden the vehicle slowed down, I noticed most of the warning lights were on including the check engine light that was blinking. I Happened to be near a GMC dealership which previously did repair work on my vehicle and left it with their service center for a diagnostic inspection. A week later my service advisor contacted me with their Vehicle condition report that my vehicle had camshaft and internal engine group issues. He quoted repairs but recommended replacing the engine. Repair or engine replacement $21,296.51. Six months before this issue I had the same issue the warning lights and it resorted in replacing the brake control cylinder. Once repaired no issues/messages or symptoms with my vehicle until this current engine problem/replacement.

The car presented steering lock column issues with repair lights on at 50 miles. Since then, they have repaired the system numerous times and replaced that system fully twice. They also replaced the manual start system and six other pieces of the car over 18 visits to two different Chevy dealerships. The car still reduces speed and stops acceleration, has electric issues in the windows, lights and gate etc.

Vehicle suddenly lost breaking power while driving . The vehicle system shows Antilock Braking System issues. Losing Break power while driving has serious consequences

On 12/3/2025, I moved my car in the driveway at 11:15am EST without any issue. At 6pm EST, myself and 2 young daughters got into the car to head out an hour away. As I went to drive away, I stepped on the brake and the car did not immediately stop…the brakes failed and came to a rolling stop. At that moment all types of warning and lights lit up the dashboard. I placed the car in park exactly where it was in the driveway and left it. I also tried to select the Ebrake and it would not engage. I called the dealer first thing the next morning as that had been closed at the time it happened. I was told to bring it in and not to drive it so nobody in my car or else would be at risk. The car was towed at my expense to the dealer. When I got in touch with the dealer that afternoon to get a status. They advised the believe the BCM needed to be updated because it seem to not be communicating properly but wanted to keep it over night to retest it before they sent me home with it. Going to point out several things…thankfully I had not left my house, as I live on a mountain and should that have happened while descending it could have been catastrophic. No warning or anything that the brakes would fail! According to records it shows the did a recall update back in Feb 2025 regarding the BCM- however, how are we sure it truly was fixed or was defective. GM/Chevy needs to take accountability for this defect and safety hazard that could result in death. In reading forums, I am not the only o

I dont believe the correct fix is changing Oil Viscocity

I bought this 2023 Chevy Tahoe rst brand new from the dealer and about a few months of owning it I noticed that the truck was needing oil before the next oil change. It’s as if it was consuming itself. This continues for month until last week when the truck died on me. I was able to jump start and everything worked fine for a day. The next day things got worse. I was on the highway and truck started shaking and giving off all kinds of codes. I took it to dealer and they said I needed a new battery but that there was also an engine problem. I bought a new battery and none of the messages on dash resolved like I was told. The truck is u drivable motor is knocking and was even making loud popping sounds. Of course my truck just hit 64,000 miles so gm is saying I’m out of warranty. I should not be having these types of issues on an almost brand new truck that I’ve owned 2 years. Engine light is flashing and dealer said this means major issue.

2nd Powertrain failure in 4 months in 2023 Tahoe with 6.2L engine. The first being the Camshaft and lifters failing at highway speeds, which was repaired. The second issue the engine seized while on a tollway going approx 70 MPH with my spouse, children, and family in the vehicle. We were able to coast to the shoulder while waiting on a tow truck. Because of the engine being seized, the Tahoe is waiting on the engine to be replaced. While we wait, we were told they have no loaner vehicles and there are no GM rental vehicles available with who they contract through. Having a 2023 leased vehicle fail twice in 4 months with children in the vehicle is unacceptable and brings to question the safety and reliability of the vehicle moving foreward.

The idler pulley was squealing. Dealership I took it to said this was the 3rd one they've had to replace in the last few days.

I was driving on an interstate when the vehicle check engine light came on and it went into limp mode causing the vehicle to go into low speed in the middle of traffic. Check engine light code P0747

While driving down the road, we heard what sounded like a gunshot into our vehicle! I pulled over and my top panoramic sunroof had exploded! There was no “point of impact” - no rock or falling debris, we were only going 45mph. It blew up and left fracture lines throughout the sunroof glass from the explosion. I just bought this car less than a month ago from the dealership (used but only 33k miles).

While driving my Tahoe on the highway at normal speeds approximately 65mph. I tried to exit freeway and my brakes were unresponsive. At this moment i began to allow the vehicle tto slow down on its own. I was able to safely exit the highway and the dealer ship was right off the exit. at low sppeeds i could push the brake pedal all the way down and acchieve some braking capability.

The engine in my vehicle has experiences major failures in valve flap adjusters, multiple valve failures, valve cover issues, and over consumption of oil by over a quarter in a week and a half of average driving. My safety was put at risk because the engine failure resulted in traction control malfunctions while going 70 mph up hill on a major interstate. This led to extreme shaking which did not stop until slowing down to below 15 mph. Luckily I was a mile from an exit and was able to coast off the road quickly; it was decent enough weather, and I was less than 5 miles from my destination so I could creep between 15-30 mph to not exacerbate traction control alarms. That slow mph did back up traffic behind me. As far as I am aware the problem was likely reproduced by the dealership service tech, which led to their recommendation to replace the whole engine. They do not consider it to be covered by any warranty anymore. The engine may be in their possession still, but I am unsure. There were zero warning lights/prompts from the vehicle that anything was going wrong prior to the shaking and loss of traction control at high speed. The dealer service team suggested that my high miles led to the engine failure. I do highway driving with it and have followed all manufacturer recommendations for oil changes, and even more frequent changes with OEM oil since about 80k miles. I do not think this engine should have failed at this amount of mileage. I made note of oil consumption around

On several occasions while operating the vehicle during inclement weather the windshield wipers intermittently stopped working. Restarting the vehicle several times did not remedy the problem. Once the vehicle was parked for a while the wipers started working again. This vehicle has been to the dealership regarding this issue numerous times and sent back in service with a message from the technician, could not duplicate the complaint.
