2024 Chevrolet Silverado 1500 complaints

On Febuary 13th 2026 I was involved in a wreck where I re-ended another stopped vehicle. There was no warning light or automated braking executed. I braked hard but not soon enough.There was no malfunction warnings or lights displayed before (or after ) the accident showing it to be inoperative. It has been in to the dealer 3 times since. Yes it is available for inspection. Was told that it will not work if you have your foot on brake or accelerator by one technician. This truck use to brake for no reason even going 70 mph on highway. I am pretty sure GM has reprogramed to fix that issue leaving the sensitivitu so low it now does not work at all.

Complete engine failure on the highway, compete engine and power lockup, towed back to dealership where complete engine lockup was confirmed. No prior issues, no other damage contributing to failure. Claims not to be covered under current recall, advising the recall be extended to all 6.2 19-04 Chevy models as I experienced the same engine failure as recall states.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that the vehicle had experienced a tailgate failure listed in NHTSA Campaign Number: 24V060000(Latches/Locks/Linkages); however, the VIN was not included in the recall. The local dealer was contacted and repaired the vehicle. The manufacturer was made aware of the failure. The failure mileage was approximately 5,000.

The all around vehicle camera system fails on average every 6 months. As the dealership is far away in our area, I have to take a 1/2 day to full day off work to take it over. I believe we are now on the third replacement camera module, in need of a fourth that was just replaced less than two months ago. GM makes it unreasonable to deal with. They require you drive over to the dealership just so they can see the same problem is occuring and only then will order parts, requiring a second appointment. The problem is the same and this is just adding more time to the failing safety issue which is of major concern because we can't just drop in easily because we are in a remote area. It sometimes takes over a month for me to be able to schedule a time to go over there --- so I go many weeks with a failing camera system.

L87 engine failure

5/4/26 Traveling at highway speed when motor quit, would not restart. Spent additional funds $682 having towed back to Selling dealer in my hometown and a rental car. Dealer reports motor seized and will be replaced. As of 6/9/26 dealer reports no information available for timeline on receipt of new motor to replace

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that the audible rear park assist system failed to activate while reversing, causing the vehicle to strike a pole. The vehicle was taken to a dealer but was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 21,000.

The 6.2 liter engine has been recalled. The problem is if you pass inspection you are now required to use a higher grade of oil. This results in an additional cost of about $50 per change. The reimbursement of the difference should have been covered by the recall as this was not an intended cost when I purchased the truck.

On [XXX], I was going to Atlanta, the truck started hesitating harshly while I was passing another driver on a two lane road. The truck wouldn’t accelerate and the paddle seemed to be stuck, I had to pull off the road to avoid a head on collision. On the 30th of May, I took the truck to Allen Turner in Pensacola, Florida where I purchased it and reported the issue, the service department was closed and they sent me next door to a Chevrolet Dealership, which was also closed. On today [XXX], I took the truck out for a test drive, and I had the same incident happen, but this time I pulled into a gas station and shutdown the truck. Once I turned the truck back on, the check engine light came on. I didn’t think I would make it back home, because the truck didn’t accelerate correctly, and when I pressed the gas pedal it didn’t accelerate and was making different noises. The pedal seemed to be stuck, with no acceleration. I recorded a little bit with my phone while trying to drive, but it’s not the best.

L87 6.2L engine failed. Loud knocking, no oil pressure, engine stalled and would not restart. This happened despite GM's recall where they changed to 0W40 oil.

Truck engine shut off doing 60. Has major recall and issue these trucks are unsafe i was very scared.

The primary failure is in the electronic transmission control system and engine wiring harness assembly, specifically throwing diagnostic trouble codes P0700 (Transmission Control System Malfunction) and P0717 (Input Speed Sensor Circuit No Signal). The authorized dealership identified a critical issue with the engine harness chafing, but their subsequent repair attempts have failed to resolve the recurring powertrain failure. The complete vehicle and all affected components are currently parked and fully available for immediate physical inspection at my residence upon request. While operating the vehicle at highway speeds, the powertrain abruptly loses throttle response and forces itself into a severe, uncommanded "Reduced Power / Limp Mode." This creates a severe safety hazard by instantly dropping vehicle velocity on active interstates and high-speed roadways, leaving the vehicle unable to accelerate out of harms way or merge safely, placing myself, my passengers, and surrounding motorists at immediate risk of a high-speed rear-end collision.The malfunction has been repeatedly confirmed and documented by authorized GM service agent Rountree Moore Chevrolet (Lake City, FL) across three separate service visits. The dealer confirmed the active trouble codes and attempted various repairs (including Transmission Control Module reprogramming on 04/24/2026, engine harness chafing repairs on 05/19/2026, and auxiliary fluid/battery adjustments on 05/21/2026). The persistence of the

Driving 70mph on the interested, the vehicle put itself in neutral. I pulled over and turned off the engine. I started it back up then it stalled at the next stop light. It would not turn back on. It had to be towed to the dealership. Turns out it was the 6.2 engine recall issue. It has been in the shop for 5 weeks and still waiting on repair parts.

There is a bad glare that comes off the hood scoop on the bison edition that blinds a driver while driving causing a high risk of an accident

Engine failure, list of power in the number 3 lane roll across traffic pattern to side of road avoiding a rear end collision, yes on second engine 6.2 yes engine has been inspected and replaced no warning with both times of engine failure

This truck has the feature when you are stoped the truck will turn off then turn back on. My truck has not had a problem yet, but I know several people who have. The lady from Chevrolet told me it was a problem and to file this complaint. Thank you very much. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Tailgate opened on its own while driving down the interstate. Since then, anytime I open a door or use the drivers door to unlock the truck, the tailgate drops. The button on the tailgate does not open it, I have to use the FOB. I frequently carry construction materials in the bed, the tailgate dropping on its own with can put others at risk for serious injury or even death. No warning lamps, have not brought to the dealer, there is a recall for this issue, but my VIN doesn't match

Vehicle had died before and was brought to dealer but was restartrd, no problem could be found. Two weeks later, engine locked up on a 70mph highway. With children and wife in vehicle. Could not restart. Had to be towed to dealer. No previous lights or warnings before engine locking up.

The contact owns a 2024 Chevrolet Silverado. The contact stated that while driving at an undisclosed speed and also while the vehicle was parked, a “Service Transmission Unable to Shift” warning message was displayed. The vehicle was taken to the dealer, where it was diagnosed that the PCM and the shifter had failed and needed to be replaced. The vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 40,129.

I was driving home from work, and dash warning sign came on and told me to start engine. I was currently driving at approximately 60 mph. When i came to blinking red Light i went to accelerate and truck was unresponsive. it would not accelerate and engine was off. I went to start engine and it just cranked with no start. I used onstar to get a tow truck. I was broken down in the middle of an intersection and had to wave traffic around me for 1hr 45 min. Finally tow truck came and took truck to local chevy dealership. Upon inspection they stated that it needs a new engine. I had the truck in the chevrolet dealership in feb 2026 to have the 6.2 recall done, they performed the full recall and said everything looks good. truck has approximately 60k miles on it. it failed a few months after inspection. They stated they have ordered a new engine and it would be approximately 4-6weeks minimum. Truck is sitting at the dealership

While exiting a highway via an off-ramp, the vehicle experienced a sudden mechanical failure consistent with internal engine/bearing failure. During deceleration on the off-ramp, the engine began to shudder violently and immediately lost power. The vehicle was unable to maintain normal operation and became unsafe in an active traffic environment. After coming to a stop, the engine would not restart and the vehicle was completely inoperable. There were no prior warning signs or alerts before the failure occurred. The issue developed abruptly while the vehicle was in motion. The vehicle required towing and dealer inspection. Diagnosis confirmed internal engine damage / bearing failure / engine seizure. The repair required engine replacement This failure is consistent with widely reported issues involving GM 6.2L V8 engines (model years 2019–2024) experiencing bearing failure and catastrophic engine damage. The same failure characteristics appear to be present in this vehicle. This represents a serious safety concern due to the sudden and complete loss of engine power and inability to restart the vehicle while in a traffic environment, creating risk of collision or roadway obstruction. The vehicle had approximately 65,000 miles at the time of failure.

While driving, the truck suddenly Boggs down and gets sluggish. A message appeared once that said reduced acceleration drive with care. It is dangerous because it loses power and stalls in front of other vehicles. I took it to the dealership on Friday the 17th and they said it was the crank position sensor. They ordered the part and I took it back on Monday the 20th and they replaced the sensor. Today, while driving down the highway it did the same thing again. I will be taking it back to the dealership tomorrow. The truck has 26,000 miles on it.

I am reporting a safety defect involving a GM 6.2L L87 engine. My vehicle was included in the GM recall related to engine failure (loss of propulsion). The recall remedy was performed, and the engine was replaced under recall/warranty in August 2025. After the recall repair and engine replacement, the vehicle experienced a second catastrophic engine failure, on April 21st. The engine failed again while on a highway, resulting in loss of vehicle function and leaving me stranded. This occurred after the manufacturer had already attempted to remedy the defect. The vehicle has now been out of service for an extended period (approximately 2.5 months total across both events - and ongoing), and I am continuing to make payments on a vehicle that is not operable. This appears to be a failure of the recall remedy itself, not just the original defect. I am concerned this represents a broader safety issue involving post-recall failures of the L87 engine, as currently under investigation. I am requesting that this incident be included in the ongoing federal investigation into GM 6.2L engine failures.

Was driving the truck on the highway at 75mph when suddenly the motor revved up in rpm’s and vehicle lost all power. There was no warning lights or any limp mode or anything as such as far as warning. The truck lost all power and could hear metal to metal sounds and turned off the motor. I was able to coast the truck to an off ramp in 70mph traffic. The truck would not turn back on and vehicle was immobile, had to have the vehicle towed by a flatbed to a gm dealer near by. The dealer gave me a loaner pickup and hasn’t looked at my vehicle yet. I bought this pickup less then 3 weeks ago and the L87 recall and oil change had been done prior to me buying it. I was just happy that the truck didnt full shut down at that speed and cause a crash etc. Dealer said motor failure to me and couldn’t confirm a turn around time frame for my truck to get back to me.

Transmission- lost reverse and some forward gears too. Without any warning signs and no check engine light until hours after. It is going into the dealership on Monday (4/20) and this all happened on (4/17/2024)

On 04/16/2026, while driving, vehicle received and completed a software/firmware OTA update. A second update completion prompt was received while still in motion. Shortly after, while stopped at a traffic light, the auto-start/stop system re-engaged and the vehicle appeared to restart normally. Upon stopping to refuel, remote key fob auto-start failed to respond. Vehicle was started manually and driven to the next location. On arrival, remote key fob auto-start failed again. Used interior push-to-start — vehicle started but displayed an active Check Engine Light. Connected vehicle app diagnostic scan of the Engine and Transmission System returned two WARNING flags requiring service: - Transmission System — Schedule Service Now - Engine Electrical System including Charging and Starting System — Schedule Service Now All other scanned systems (Air Induction, Fuel Management, Engine Cooling, Throttle Control, Ignition, Variable Valve Timing, 4WD, Displacement on Demand) returned OK. Both faults appeared immediately following the OTA update. Remote start failure at two consecutive locations and the Check Engine Light activation are directly correlated in timing with the update applied on 04/16/2026. No fault codes have been pulled yet — dealership service appointment pending. This is not the first instance of an issue after updates are applied, between the infotainment system blacking out, rear camera or ADAS not functioning as well as sporadic crackling sound almost like electric

These are two separate incidents. The first one is the seat moves to the left or to the right given the direction of the vehicle. The other incident was when I was reversing into a parking spot. The gear shifted out of reverse and just was in a floating stage. I then had to put it back into reverse to continue it did it twice

Loud ticking sound from engine corresponding with engine speed (faster as the rpms increased). Took in to dealership out of concern and the rod bearings were spun necessitating a full engine replacement. This was only 4 months after it passed the inspection for Recall - L87 Engine Loss of Propulsion (Related field action: See Special Coverage N252494003).

2024 6.2L Silverado Trail Boss, engine failure at 22k miles on 4/13/26. Dealer confirmed the failure (not sure which bearings seized since engine has not been torn down yet, was either crank or rod bearings) and ordered a new engine 4/14/26. I was driving on the interstate and the engine started lightly shuddering during acceleration, showing some loss in power and shifting oddly but no check engine lights and nothing too alarming to immediately pull over. After several miles of this, the engine started to emit a loud metal on metal squeaking/scraping sound when on the throttle but stopped when I would back off the throttle. About a mile later, the truck just shut off at 70mph and went to neutral as I was about to get off an exit to evaluate the issues. Dash said push button to restart as I was coasting, but it wouldn't restart so I put on my hazards and pulled to the shoulder of the highway. Once stopped, it automatically shifted to park and would not crank or allow me to shift to neutral. Flatbed was called and brought it to the dealer. Side note: The truck passed the Pico test 1/15/26 at 20k miles and was sent on my way with the thicker 0W-40 oil. Oil was changed every 5k miles and ran 93 octane.

I was traveling at highway speeds when the engine suffered a sudden and catastrophic mechanical failure without any prior warning lights or symptoms. The engine began knocking violently, locked up and put the truck into a brief skid before freeing up, followed by an immediate loss of oil pressure and a total loss of motive power.This sudden shutdown caused a brief loss of vehicle control as the power steering assist was compromised, creating a hectic and dangerous situation while I was surrounded by high-speed traffic. I was forced to navigate across multiple lanes to reach the shoulder. Crucially, this vehicle had the L87 Safety Recall (NHTSA Recall 25V-274 / GM Program N252494000) performed on July 8, 2025. The "remedy" provided by the manufacturer—which involved an oil viscosity change and a new oil cap—failed to prevent the catastrophic bearing/crankshaft failure it was intended to address. This represents a failed recall remedy that resulted in a life-threatening safety event. The vehicle is currently at a dealership awaiting a complete engine replacement.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving at various speeds on several occasions, the vehicle lost power and then stalled. The vehicle was restarted after each failure. The check engine warning light was illuminated, and the message "Reduced Acceleration - Drive with Care" was displayed. The vehicle was taken to a dealer on several occasions, and the dealer retrieved DTC: P2732 and P0700. The contact was informed that the valve body needed to be replaced, and the transmission was leaking transmission fluid, but the leak was not located. The valve body was repaired, and the transmission fluid was topped off, but the failure reoccurred 2-3 months later. The manufacturer was not notified of the failure. The failure mileage was 10,900.

On 04/03/2026 at approximately 0545 I was heading in to work . While at a complete stop I proceeded to accelerate on the Highway 54 BRF WI. 54615 when the truck made a clunking noise and jerked. At which point the engine light turned on along with reduced speed message across the display screen. unable to pull over safely at the moment I had to proceed no faster than 25 MPH on US 54 hindering all traffic behind me. once safely pulled over I placed the truck in Park, then neutral , which made a loud clunking noise and absolutely no reverse. Truck towed to local dealership. Vehicle had been inspected by Dealer tech. Tech stated faulty valve body in the transmission.

When driving at slow speeds, less that 10 MPH, the engine shuts off and vehicle shifts to neutral. Message is displayed on driver console Press Start Button to restart. Only the engines shuts down as all displays, entertainment center and controls are still displayed. Pushing the start button restarts the engine. This has occurred several times since purchasing the truck however it has occurred 2 times in the last 45 days. This issue has happened while driving in slow traffic on the interstate and is concerning when it occurs as I come to a complete stop without warning creating a possible rear end accident. It was first reported to my Chevy service dealer on 2/21.2025, The Chevy tech stated they could not duplicate the issue so no remedy has been offered. The issue continues to happen and I will be returning to my Chevy service center for another report of this continuing to happen.

Turning into the driveway and the truck shut off. Place in park and the truck started right back up.

What is happening with my vehicle is a major safety concern in my opinion for myself and for my family. I purchased the vehicle on February 18,2026 from Ryan Ford in sealy,TX with approx 32,800 miles. The first incident was on March 16 with 33,718 miles, my daughter and I went to leave the Lowe’s parking lot and my vehicle would not go in reverse. It however would go in drive, so after being pushed back out of the parking spot we left for our home.(this part of not going in reverse I do have on video) Once on the feeder road and up to approx 45mph my vehicle went completely out of gear and had to coast to a stop on the side the road. Turned vehicle off and on and it went back in gear, after making it home I made and appointment with the dealership and dropped it off that day. I was informed no codes came up and the dealership could not get the issue to duplicate so I received my vehicle back. The second incident was on March 21 trying to leave the convenient store, I put my vehicle in reverse and pressed on the gas to go backward and nothing happened. Then I pressed on the gas again and it threw my vehicle in reverse and jolted my truck back several feet before I could press on the brake. Luckily no one or no object was behind me. The third incident was on April 3rd trying to leave Walmart. My truck would not go in reverse again. I pressed the gas pedal several times and out of nowhere again it threw itself in reverse and jolted my truck back again. (I also have this on video

The 6.2L V8 motor is known to have faulty internals. I was driving down the highway and the motor shut off. The vehicle needs a new motor now. GM has offered an oil viscosity change to 0w-40. That was done 20k miles ago. This vehicle now needs a new motor

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving approximately 55 MPH, the vehicle started jerking and shuddering before it stalled. There was an abnormal grinding sound coming from the engine compartment. There was no warning light illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the engine needed to be replaced. The vehicle was repaired. The contact researched online and related the failure to NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not associated with the recall. The manufacturer was informed of the failure. The failure mileage was 13,222.

Purchased June 3,2024 Feb 3/2025: serial data gateway module recall. All indicator lights on, ac control and radio inoperable, instrument panel displays various issues. That recall was serviced. February 28/2025: couldn’t see how fast I was going, don’t know how much gas I had. AC controls and radio no operable, all information indicator lights on again March 1/2025: duplicate issues from 2/28 January 17/2026: at a red light, car shut off and wouldn't turn back on in the middle of snowing road, indicator lights all on and present could not restart car, police present-had to unhook battery due to safety concerns March 18/2026: , all indicator lights on, speed limitation to 62 on the highway, loss of power steering, didn’t turn back, called for tow and the morning after turned on and check engine light off Vehicle in at dealership: March 26-27, 30-31: Could not replicate issue, no r/o codes 4/1 Contacted by Brian with GM Corporate- “can’t do anything until the check engine code goes off again”.

Truck shut off while driving in traffic managed to steer it off the road, towed to dealership with p0016 code as well as a bunch of others. known recall issue passed gm pico test a month earlier. now when I log in here to view recalls it says 0 recalls not repaired. Now truck has to get a new engine.

Summary of Incident: On March 28, 2026, while traveling at 70 MPH on the Florida Turnpike, the vehicle suffered an instantaneous loss of motive power. The engine died abruptly with no warning. Upon reaching the shoulder, the electronic transmission locked, refusing to shift into Neutral or Park. The engine cranks but will not start. 1. Component Failure & Availability: The exact component is currently unknown, but the failure involves the Powertrain, Fuel System, and Electronic Transmission Control. The vehicle is currently at an authorized dealership and is available for inspection by the manufacturer or NHTSA upon request. 2. Safety Risk: The sudden loss of power at highway speeds created an immediate risk of a rear-end collision. Because the electronic transmission locked and would not allow the vehicle to be shifted into Neutral, it became a fixed object on a high-speed shoulder. It could not be pushed to a safer location, increasing the risk of a secondary accident. 3. Problem Reproduction: The vehicle was towed directly to an authorized Chevrolet dealership. As of this filing, the dealership is in possession of the vehicle, but the failure has not yet been reproduced or confirmed by a technician as they are awaiting formal diagnostic commencement. 4. Inspections: The vehicle was inspected by a roadside towing professional for transport. It is currently at the manufacturer’s authorized service center awaiting a formal diagnostic inspection. No police or insurance inspect

1. Transmission shudder at highway speeds between 64 and 83 miles per hour. 2. Pour fuel economy; 12.5 mpg @ 65 mph, 11.8 mpg @ 70 mph, 8-9 mpg @80 mph towing a 2025 utility trailer wiith motorcycle approximately 1800 pounds.

I am writing to report a serious safety concern involving my 2024 Chevrolet Silverado that resulted in a child being locked inside the vehicle with the key fob present inside the car. On March 25 2026, after parking and turning off the vehicle, I exited the driver’s seat with my key fob inside my purse, which remained in the front of the vehicle. I then walked around to remove my daughter from the back seat. During that time, she climbed into the front seat and pressed the interior door lock button, locking all doors. My daughter has autism and is not able to follow instructions or unlock the vehicle on command. As a result, she was locked inside the vehicle with the key fob present inside, and I was unable to gain access from the outside. The vehicle did not prevent the lock from engaging, nor did it allow me to open the door despite the key being inside the vehicle. This situation required emergency assistance (911) to safely remove her from the vehicle. I understand that many vehicles have “lockout prevention” features; however, in this case, the system did not account for a vulnerable occupant inside the vehicle. Allowing the vehicle to be locked from the interior while the key fob is inside—and without any external override—creates a significant child safety risk. I am requesting that Chevrolet review this design behavior as a potential safety issue, specifically: - Why the vehicle allows interior locking when a key fob is detected inside - Why there is no external overr

I had my oil changed and the next day the check engine light came on. I looked on the Chevy app to see what it was and it said Varuable Valve timing issue. I Click further into the app warning and it said, Engines equipped with this system use sensors that regulate the opening and closing of the intake and exhaust valves to optimize performance and efficiency. I live 3 and a half hours away fro. The dealership so I had some mechanics look at the truck just to see if they could pin point what the issues was exactly. They didnt pull or work on anything just looked around listened and plugged in a code reader. The code reader found some codes that had to do with 3rd stage valve timing issues and VVT. And 1 or 2 other codes. But they didnt know exactly what was wrong. I had my oil changed 1 more time to see if maybe that was the issue. It did not fix the issue. I called the dealership to make a appointment. I brought it in and get a call that the cam shaft need to be replaced. It was in the shop for about a month and when they said it was ready. I went to pick it up and as I was pulling out of the dealership parking lot. The check engine light came on and I drove back and it had the same codes. And now it is being worked on again. The safety side is if it looses power while im going 65 mph it could be really dangerous. Becaue there could be metal shavings in the oil possibly.

My truck engine stopped working while driving down the road causing me to lose power and I was not able to exit the roadway. There were no warning or messages until the loss of power and dash stated to "restart the engine". This was not possible. The truck was towed to a Chevy dealership and they confirmed the engine seized up do to unknown engine failure. This is a 2024 6.2L engine with 45000 miles that is NOT under recall. The dealership replaced the engine under the powertrain warranty.

I was driving down the highway and the vehicle suddenly shutoff without any warning. I coasted down an off-ramp and came to a stop in the middle of a round about. The vehicle would not re-fire and had to be towed to dealership. When at dealership it was discovered the engine failed. This is a 2024 6.2 liter engine that was not included in recall. I could have caused an accident on the highway as I suddenly lost power. People who were included in this recall received a 10 year 150K warranty on the new engine. My truck should be included in that.

The DEF tank failed making the exhaust system malfunction. This puts the vehicle in limp mode.

On 1/31/2026, while returning from an AKC event with my XXX year old border collie, I was traveling on IXXX at approximately 70MPH in the left hand lane passing other traffic. As I started up a hill in a remote area, I began to hear a knocking sound coming from the engine compartment that sounded like a rod knocking and the truck began to struggle to continue up the hill. It then lost all power, a message stating to shift to neutral and restart flashed on infotainment screen, I shifted to neutral and pushed the start button, but everything went blank. I had to struggle to merge back into right lane and eventually over to the breakdown lane, approximately 5 miles from the nearest exit. I was forced to remain on the side of a busy interstate for approximately two hours during an unusually cold day for Florida that consisted of snow flurries while waiting for roadside assistance. Luckily, I was able to arrive at the dealership 5 minutes before closing and was able to get my truck checked in. The service writer knew exactly what the likely issue was when I described my ordeal, and it was partially confirmed when she pulled the Christmas tree of codes from the computer that my truck was throwing. It should be noted that the truck would not restart after the catastrophic failure that stopped the motor at 70MPH on the interstate and would not shift to neutral for the tow truck operator to load or unload onto flatbed. Subsequently, Techs determined that engine failed due to suspected

Component: Faulty coolant control valve causing reduced acceleration and check engine light to come on. Fan is constantly on when reduced acceleration is displayed. Safety: can overheat, reduced acceleration can cause an accident. Problem reproduced: Dealer did check and confirm codes and errors. Dealer confirmed item failed. Coolant control valve needs to be replaced.

The tailgate has opened 4 times while I’ve been driving. There was one incident in which an object in the truck bed fell out onto the road. Other drivers are at risk for serious injury or death due to objects falling out. I have read other incidents of this happening online to the Silverado 1500 models however Chevy has only issued recalls for the 2500 and 3500 models. The problem has not been reproduced or confirmed by the dealer and they will be inspecting it in the next coming days. There were no warning lamps or messages indicating failure or that my tailgate was open. I’ve provided photo documentation showing me closing the tailgate as well as a photo of the object falling onto the road.

After taking in to dealer for recall diagnostics and higher viscosity oil change a couple months later. Heard a noise while driving on interstate, lost cruise control, stability system, engine light came on with a ECS. Kept driving on the interstate until we got to a red light and the engine died. Cranked starter but hard to start and ran rough and died multiple times. Feathered throttle to get over 1K RPMs to get it off the street. Towed to nearest Chev dealer. P300 code. Tore engine down. Here is what dealer documented: CUSTOMER STATES CHECK ENGINE LIGHT IS ON WITH SERVICE TRACTION & SERVICE ESC MESSAGES. ENGINE IS RUNNING ROUGH AND WILL STALL. TOW IN. Valve Spring Replacement - Replacing the faulty valve spring on the cylinder 7 exhaust side is necessary as it is causing the exhaust valve to remain stuckopen, leading to engine misfire and over 80% leakage in that cylinder. This service can help restore proper engine compression and improve engine performance. Op.1 CEL -CEL: Customer states 1. replaced the exhaust valve spring and valve spring seal. reinstalled components with new seals and cleared dtcs. started engine and verified the engine starts and runs but having multiple cylinder misfires. reset engine fuel trims and brought engine to operating temperature and let it run for some time. other cylinder misfires went away but still found a dead misfire on cylinder 7. removed and swapped spark plugs with no change. noted the spark plugs have some exhaust build up on the
