Power Sliding Glass window on rear of vehicle had a thermal failure, resulting in heavy smoke buildup in the cap followed by the window shattering. My vehicle has already received the recall repair, GM Program #N192265660 / NHSTA TSB #10171416, but the defect reoccurred and caused destruction to the vehicle.

The contact owns a 2018 Chevrolet Silverado 1500. After starting the vehicle, there was a clicking sound coming from under the hood, and then the sound stopped. While driving approximately 55 - 60 MPH, a fuel odor was detected inside the cabin of the vehicle. The vehicle was diagnosed by an independent mechanic, who determined that the exhaust manifold bolts had fractured. The bolts and gaskets were replaced. The manufacturer was notified of the failure by phone, and a case was filed. The failure mileage was approximately 125,000.

I purchased four tires for my truck from Firestone, each rated for 60,000 miles. After approximately 30,000 miles, all four tires developed microcracking and visible damage. I suspect the issue may be related to the quality or composition of the materials used. I contacted the Firestone location where I had previously taken my vehicle for maintenance and tire service to have the tires inspected. While an employee was assisting me, I showed him photographs of the tires on the side of the computer counter to start the process to replace them, then manager approached to me rudely and disrespectfully asking me to go to the front, replaying to him : I am showing pictures of my tires asking me to leave the store just for that. Afterward, I had the tires inspected at Costco, where I was advised to replace them as soon as possible because represent a safety issue. For the safety of my family and myself, I replaced the tires for another brand. I subsequently filed a complaint with Firestone’s corporate office, but Firestone has declined to take responsibility for the condition of the tires asking to refund me the money I paid for the tires and a relief for the way I was treated. I am attaching pictures to show the condition of all tires and PDF File an email from Firestone.

On September 10, 2026, while traveling approximately 60+ mph in the passing lane, my 2018 Chevrolet Silverado 1500 suddenly lost normal acceleration and entered Reduced Engine Power mode. Vehicle speed dropped to approximately 40 mph, and pressing the accelerator would not provide normal power. This created a safety concern while traveling at highway speed. On September 11, OnStar On-Demand Diagnostics documented ECM code P2138 (Accelerator Pedal Position Sensor 1-2 Correlation) and ABS code U0422. The TCM reported no error codes. The check-engine light later turned off, indicating the problem is intermittent. GM Technical Service Bulletin 07-06-04-019F addresses intermittent P2138 with Reduced Engine Power and possible water intrusion/corrosion affecting the accelerator pedal position circuit. After removing the driver’s kick panel, we observed evidence of previous moisture/rust in the area, but the exact cause has not yet been diagnosed. The vehicle is scheduled for diagnosis by a Chevrolet dealer. I am reporting this because the sudden loss of acceleration at highway speed created a safety hazard and to document the incident for potential defect-trend investigation.

I Tried to get a tune up and found out that the Engine need $5000 worth of engine repairs. I have changed the oil and filter every three thousand miles. Those engine are defective and the repair shops are full of the same type of repairs on that type of engine. My engine is a 5.3-liter V8, The engine started to make ticking noises out of nowhere and then it started missing badly. The repair shop informed me it would take 3 weeks before i could get it repaired at the cost of $5000.I did research on the 5.3 liter engine and found out that GM produced a engine that will cost us owners a lot of our heard money for a defect they created, This is so wrong Because i am a senior citizen. I paid over $50,000 for a limon that is just wrong.

Intermittent issues seemingly related to power or ground problems. At idle, battery voltage drops down from 14-15v to <= 12v (as indicated on the voltmeter on the dash) while turning the steering wheel. "Service StabiliTrack" message shows up on the screen, and the steering becomes very difficult. Last night this issue happened and the truck completely lost power including interior lights, headlights, radio, accessory power, and the engine even turned completely off. This happened in the middle of the street as I came to a stop in front of my house and was going to reverse into my driveway. Cycling the key was enough to restart the truck and the power came back on. When this first happened to me almost two years ago, I brought the truck in for transmission concerns (resulting in a transmission replacement) to my local dealer, and I explained what had happened and they could not reproduce the concern and said everything checked out fine. I've had strange electrical problems pop up every now and then including this StabiliTrack warning message and a trailer brake warning when I am not even hauling a trailer, but this is a major safety concern. My wife and daughter were in the truck with me when it happened, and if the power ever shut off like this on the freeway, major road, or even off-roading, it would be disasterous.

The transmission went out before it hit 100k miles. It had to be completely replaced which cost me several thousand dollars.

Several times, while driving, the truck will simply shut down. It will becoime difficult to steer, then the engine will stall, killing the rest of the steering and the breaks as well as the dashboard, radio, etc. This can happen at any speed, low speed especially. I will give you an approximate date below, but there have been several incidents. The truck was looked at by our local mechanice, who could not find a problem and by the dealership electrical specialist who has also been unable to locate a problem.

My truck has been shuttering when accelerating and hard shifts periodically. The engine is also tapping. I have right at 74000 miles. regular oil changes and maintenances.

I was driving down the highway, turned on left signal to make left turn. the truck engine died with no warning, could not steer, almost ran into bank. all the dash lights went black, no power at all. the radio starts playing on occasion without being turned on. the clock loses time when it wants to.the blower on the ac comes on and off when it wants to.have had battery, alternator, ignition system checked. all these check out just fine. there were no codes , and absolutely no lights or warnings on dash. our truck was still in the highway lane. luckily the police stopped and assisted by directing and holding up traffic as necessary. i have had similar issues on other occasions but was always more brief and the truck would crank back up right away.

My son was driving down the road going 30 and both curtain liner airbags deployed and the left side hit him in the head . GMC is denied my claim twice after careful consideration. That was the explanation and we have an undriveable truck with a truck note . Incident happened may 31 and they denied me July 23.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed and coming up to a stop sign, the vehicle lost braking functionality. The contact stated that the “Service Brake Assist” warning light was illuminated on the instrument panel. The contact was able to make a right turn and pumped the brakes for the vehicle to come to a complete stop. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 117,000.

There was premature torque converter failure that’s has taken out the transmission unexpectedly. I was coming from a side street to get onto a main highway and as I left the stop sign the truck stalled upon take off and I was stuck half way on the highway and halfway on the side road. Until it jerked hard back into gear and pulled off. If the torque converter wouldn’t have caught in time then it could have cause a serious accident. The truck only has 95,000 miles and is a 2018 Silverado 1500 LT 4x4 with the 6l80e transmission. I had to park the truck until the following week when I could take it to dealership and they diagnosed it and quoted me for a new transmission and torque converter. Something needs to be done about these transmission as they are a serious safety concern. No police report was made since there was no accident but there definitely could have been.

The contact owns a 2018 Chevrolet Silverado 1500. The contact was alerted by OnStar of a failure with the stability system. While the contact’s husband was driving 45 MPH, the vehicle was jerking; the brakes were sticking while the brake pedal was depressed. The failure persisted while driving 50 MPH. The driver used the back roads while driving to the residence. The brakes and ABS warning lights were flashing quickly. The vehicle was taken to AutoZone, and DTC: U0422, was retrieved. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that the VIN was not included in NHTSA Campaign Number: 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control (ESC); and referred the contact to the NHTSA Hotline to report the failure. The approximate failure mileage was 113,000.

Purchased used 6/12/2026 at 188,882 miles from a franchised Chevrolet dealer. The integrated trailer brake system master fuse and passenger-side turn signal fuse were blown at delivery. When the fuses were replaced, the trailer brake system faulted and the failure disabled the ABS, traction control, and StabiliTrak (electronic stability control). Significant safety concern: with the master fuse blown/open, the vehicle displays NO warning messages of any kind — the safety-system failure is completely masked while trailer braking is inoperative. The warning cascade only appears when a good fuse is installed and the faulted circuit is energized. Separately, at approximately 12 days and ~1,700 miles after purchase, the engine began knocking and set diagnostic trouble codes; a dealer repair order dated 7/6/2026 documents the knocking complaint with no work performed. The vehicle is currently parked as unsafe to drive. No crash, injury, or fire. Reporting so the ABS/ESC failure mode — and particularly its masking behavior when the fuse is open — is on record for this VIN and vehicle line.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at approximately 60 MPH with cruise control activated, the vehicle shuddered and multiple warning lights illuminated, including the check engine, check oil, fasten seatbelt, traction control, and brake warning lights. The vehicle experienced steering overcorrection and lost power. The vehicle was steered to the side of the road and slowly driven to an independent mechanic shop, where it was diagnosed that the engine needed to be replaced; however, the vehicle was not repaired. The vehicle was then taken to a dealer, where it was diagnosed that the first and second pistons and lifters needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 101,000.

The engine lifters and camshaft started to fail at 114,000 miles. I had to have it repaired at a dealership and it cost over $10,000. I had completed all recommended maintenance prior to the failure. 500 miles after that repair was completed, my transmission overheated and completely left me stranded on the side of the road. I had to have it repaired at a dealership which cost $$8,000

While pulling car trailer down the interstate on 6-27-26 at 70mph, my Free Country ST205/75R16 D106 10 ply trailer tire with less than 200 miles on it blew out. This was the spare for 2 years and has 9/32 tread depth on it still. I recently this spring rotated it to the LR of the trailer. Pieces of the tire blew onto and hit a passing SUV. Luckily nobody was hurt and I was able to get to the shoulder with only some fender damage. The tire was changed and with research I found the warranty was only 1 year. I was not happy with this, but moved on and bought another tire to replace it. Yesterday 7-4-26 I pulled the same trailer and upon arriving to my destination noticed another one of the tires that was purchased at the same time is separated badly all the way around and is on the verge of blowing out. This tire has been on the trailer since I bought the set of tires new, and has just under 8/32 tread left. These tires are under 3 years old, and used well under weight capacity. I keep them aired up near the max to save gas, and check them regularly. I cannot be the only one having problems if 2 out of the 5 I bought are coming apart already. Ultimately these are a safety hazard. If that had been a motorcycle beside me, or a large enough chunk flew off. Someone could have been killed. Pics available upon request.

I was driving on the highway at about 70 mph and the passenger side lower control arm where the ball joint sits broke. It messed up the passenger fender and tire along with the steering link. It also bent the upper control arm as well. The ball joints were replaced about 6 months ago.

A known radiator issue, with microcracks in radiator is producing a leak and will require replacement. There are many examples of this online for the model years 2014-2018, and are known by the manufacturer. I am having mine replaced with 95,000 miles on my truck.

I am very certain that I have proof that from the dealership a Cable Dahmer and Kansas City Missouri did break work concerning the brake master cylinder booster was replaced and it still has problem which should have been under a recall and I would like to get that corrected and received my service funds back

The truck dies when you turn the steering wheel all the way. When that happens the steering wheel jerks and could cause a crash. This appears to be a common electrical problem that currently has no recall from the manufacturer.

Vehicle was determined to be unsafe to operate per inspection performed by Mike Maroone Chevrolet on 8/26/24 immediately after I purchased from Rocky Mountain Auto Brokers in Colorado Springs on 8/8/26. It was discovered by customer immediately after sale that bank 2 catalytic converter was restricted internally (after Rocky Mountain failed to correctly diagnose and repair 3 times before and after purchase). Customer discovered emissions warranty extension and took to Maroone Chevrolet. After warranty repair inspection of vehicle determined it was not safe for customer to pick up and drive vehicle and generated a report and video showing front suspension damage so loose that could cause crash and vehicle was towed back to Rocky Mountain for repairs. Rocky Mountain has failed to provide any documentation on these repairs and many subsequent repairs including transmission replacement after many written requests. Customer cannot verify if vehicle repairs brought vehicle back to a safe condition. Almost anll repairs by Rocky Mountain has failed resulting in missing bolts, bolts falling out after transmission replacement As well as failure of many CV Axel replacements documented in their own records. Extended Warranty Company also refuses to provide documentation of transmission replacement after they supplied the part (transmission) to Rocky Mountain for installation. Customer cannot verify if in fact transmission was replaced as it was painted black. Any warranty on replaced tra

The frame of my 2018 Chevrolet Silverado 1500 has rusted through to the point of failing Maine state safety inspection at only 41,000 miles. A licensed Maine inspection station identified structural frame corrosion and determined the vehicle is unsafe to operate. A Chevrolet dealer confirmed the frame rust and stated the truck must have rusted sections cut out and welded to be made roadworthy. The vehicle is available for inspection upon request. Safety risk: A rusted-through frame on a pickup truck is a serious structural defect. Frame failure while driving could cause loss of vehicle control, separation of suspension or drivetrain components, or catastrophic structural collapse, particularly at highway speeds or under load. The vehicle is currently unregisterable in Maine due to this safety failure. The failure has been confirmed by both an independent licensed inspection station and by a Chevrolet dealership service department. This failure is consistent with a known manufacturing defect documented in GM Technical Service Bulletin 19-NA-255, which acknowledges that the wax coating applied to the frames of 2011–2024 Silverado and Sierra trucks was improperly applied by a third-party frame supplier, causing the coating to peel and exposing bare steel to premature corrosion. GM has issued this TSB but has not issued a recall, and Chevrolet dealers are not consistently performing the repair. I contacted GM Customer Assistance to request goodwill repair and was refused; the rep

I was driving on highway 20 in Cartersville ga at speeds around 55-60 mph with both of my kids the vehicle. All of a sudden my rpm’s shot up to over 5000 while losing acceleration control of the vehicle. I attempted to slow down and pull over on the side of the road to get out of traffic and was unable to get the vehicle to move forward or backwards at all. The rpm’s continued to rev out of control unless I was park. I had to shut the vehicle off for a few minutes, erase codes and attempt to move it again. I got it to move another few feet to just clear the roadway. I had to leave the vehicle on the side of the road and get both my kids out on the highway and wait for someone to come pick us up. The truck is now in the shop and I’m told that the torque converter shred to pieces and the my transmission was shot. This was a $7000 fix and the vehicle hasn’t even hit 100,000 miles yet. I also did the recommended service at 80,000 miles following the Chevy guidelines for my truck.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, there was an abnormal whining sound coming from the vehicle. There was no warning light illuminated. The contact called an independent mechanic to inspect the vehicle. The independent mechanic discovered that the camshaft and lifters were inoperable. The mechanic stated that the issue would worsen if the vehicle were continually driven. The manufacturer was notified of the failure and informed the contact that there were no recalls associated with the VIN. The vehicle was not repaired. The failure mileage was 147,000.

The paint on my vehicle has been bad since purchased, complained to dealership several times about this issue. one time when i complained the paint was touched up at dealership the issue has continued and became worst over time, my truck is a 2018 only 19,000 miles and the paint chips on the front where it looks like red paint speckled with white contacted the dealer as well as general motors corporate and the refuse to do anything i have complained about the paint every time the oil is changed at dealership after no help, i found a lawsuit was pending covering paint issues and the website recommend to register a complaint with NHTSA for recording issues thank you [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Failed/collapsed lifters associated with known Active Fuel Management (AFM) issues. These issues are documented in Technical Service Bulletins and I believe there are Special Campaigns for 2014-2018 L83 engine, but my VIN does not have a Special Campaign attached to it for some reason. I believe there are also class action lawsuits associated with these known issues, but a recall has not been issued.

Parking brake pad failure has occurred twice. Last month at 31,668 mi, truck was taken in for servicing a warning light due to TPM failure (all replaced), and I asked for parking brake inspection because I was pushing pedal to the floor in order to engage. Mechanic said "Left rear prkg brake shoe has section missing." He had never seen that before and I exclaimed that it happened first in Apr 2021 at 18,770 mi. I am not sure which side it was since it was not written on the service invoice, but I suspect the right side because during a Nov 2021 oil change the invoice included "adjusted rear rh parking brake." OEM replacement pads were installed both times. I have the latest failed pad which shows about 2 in of material missing from the shoe substrate, not the 2021. Kearny Mesa Chevy repaired this in 2021; Walt's Danville Service in 2026. No safety issue, but could have been a problem in event of brake failure an need to stop vehicle by applying parking brake that would not hold. I asked KMChevy if this should be a warranty repair or a recall issue and they refused to consider in 2021. It cannot be coincidence that this happened to Chevy OEM equipment, I suspect to both sides. I paid ~$500 each time and feel that Chevy corporate should compensate me.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at undisclosed speeds, the vehicle started shaking abnormally. No warning lights were illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 60,000.

We purchased a 2018 Fully Loaded Chevy Silverado LTZ/Z71 ($60,000) in 2019, with the idea it would last. After being super meticulous with maintenance and keeping this vehicle in top condition, we just passed the 110,000 mile mark. I have receipts of all the work/maintenance completed on this vehicle. I began to hear a ticking noise in the engine block, and the check engine light came on, so I pulled the codes and went to a local transmission/engine mechanic to find that I have a bent push rod (manufacture failure) due a failed lifter/AFM system. I opted not to take it directly to the dealer as they charge $179 base rate for diagnosis which could increase depending on the diagnosis needed. After numerous calls, I found this is a very common ($7,500-$11,000+) issue with '18-'21 models. Explored my options only to find the 2021- 2026 engines are worse with issues involving crankshaft, engine seizures and an active lawsuit with the new 6.2L V8 engines. (Silverado, GMC Sierra, Tahoe, Suburban, Yukons) I was then pointed in the direction of speaking to the GM Manufacture directly, again. I had contacted them numerous times and was told the damages, even though are not preventable and are directly due to a manufacture error. I was told I must take my vehicle to a licensed service dealer to be diagnosed. I informed them, that I was already told my vehicle would not be covered so I did not feel the need to endure additional cost only to be told the cost would again, not be covered. I

They cleared all codes and started the engine. Immediately the ABS warning came on. I am very concenedn about family, I just purchased the truck on Jan 21, 2026. Please help!!

My transmission failed at around 69,000 miles. This was confirmed by the dealership. I bought my vehicle from and was covered under warranty. I purchased my vehicle in 2019 from a Dodge dealership and it came with a 10 year hundred thousand mile warranty for the powertrain. The tech indicated that the torque converter failed sending metal fragments through the transmission, coolant lines and transmission cooler. There were no warning indicators only hard shifting clunking when shifting and shuttering at different speeds.

Transmission is having hard shift and shutter at a speed of 60/65

While pulling a 14' enclosed trailer when i left off the gas pedal there was a sudden low growl/vibration coming from the bed area of the truck. I was slowing down for a red light and it started at around 20mph. I pulled off slowly when the light turned green and was listening with my head out the window but everything seemed normal, about 2 miles down the road from the initial vibration/growl incident and running about 40mph the rear differential completely locked up causing the drive shaft to snap off the pinion yoke and left me sideways in the middle of both lanes with an enclosed trailer and alot of ticked off people cussing at me like i did it on purpose or something. Because the rear end was completely locked up, there was no way for me to move out of the road way so i had to sit blocking both lanes for 2 hours while waiting for a tow truck. There was no warning lights, the only kind of warning was the quick and subtle vibration/growling noise at the redlight.

Collapsible lifter and lift rod failure

My truck has been into the dealership repeatedly from Aug 2024 to where it sits now to this day because of the engine and the electronic fuel management system. This fuel management system has destroyed my engine by allowing excessive oil consumption to which it turns the oil black. The engine goes from v8 to 4 cylinder to save on fuel which makes the engine work harder. It causes the rocker arms and pistons to work harder which makes them fail. These problems have occurred with my truck and now the dealership wants 20,000 to replace the engine when they worked on it continuously even after my warranty period had expired. Keep in mind that they were still fixing these problems when my warranty hadn't expired yet they fail to fix it properly. I make payments on a truck that I hardly ever get to drive. I have service invoices to back up my claims. There are numerous others that are dealing with this problem and it's all over the internet so i am not the only person

An electrical component related to the vehicle's rear sliding glass window and rear defroster malfunctioned and overheated, causing smoke to fill the cabin of the truck as it was being driven down a busy highway. Immediately following the smoke, the rear window violently shattered due to overheating from the malfunction. This dangerous defect was known to exist in our model and year of truck, as documented in Customer Satisfaction Program N192265660. This bulletin shows that GM knew about this exact issue, yet allowed the vehicle to be sold and driven. This incident was incredibly dangerous and easily could have caused my wife (who was driving) to crash the vehicle due to limited sight and distraction. My wife called me following this incident and was terrified and confused. There were no warnings, signs, or symptoms suggesting an issue with the electrical component until the incident occurred. We immediately contacted GM, who advised we were not permitted to get the vehicle fixed until they completed their inspection; however, it has been nearly a week and no inspection has occurred at this time.

This complaint is submitted as additional information related to a previously filed safety complaint for the same vehicle and incident. Since the original submission, General Motors Product Assistance Claims verbally denied responsibility, refused to inspect the vehicle, refused to provide written confirmation of their denial, and ceased responding to emails and calls. GM previously instructed me not to repair the vehicle and promised a rental vehicle and tow, neither of which were provided. The vehicle remains unsafe to drive due to smoke intrusion and shattered rear glass and has been left exposed to freezing and rainy conditions. This incident appears consistent with a known rear window defroster thermal defect similar to GM Customer Satisfaction Program N192265660. GM’s refusal to inspect or mitigate increases safety risk.

There was no warning light illuminated. The vehicle was taken to an independent mechanic and was diagnosed with transmission failure. Due to the failure, the torque converter and the transmission were replaced. The vehicle was repaired. The manufacturer was notified of the failure, and the contact was informed that there were no recalls for the failure under the VIN. The failure mileage was 85,377.

We bought the truck new 2018 and started having trans issues and leaf springs popping. So, we took back to dealership and all they did was change fluid in trans and pump grease in-between leaf springs. I did get them to finally change passenger side leaf spring out, but that does no good when leaf spring they put on has the same issue. The leaf springs have to much gap in between each leaf. I told them to give me a 1,000.00 and I would go and have some made. That way, if I put a load on leaf spring it less chance they could break going down the road. Also, we have issues with radio that also did not get fixed by gm and still has the issue we can't use today. My truck also has the 6.2l engine that you guys have had complaints on. I will tell you that I'm not happy with what Gm is doing with these defected parts on these trucks. They are doing quick fixes to save them money on their screw ups and could get us killed. We are still having the issues to this day and they just brush us off. We pay a lot of money for these truck and Gm is ripping us off and costing us more money because we have to pay to fix their mistake, they should be fixing for free. All I want from Gm is get these issues fixed right and pumping grease in-between parts does not fix anything. We have to hold them accountable for these issues and make them fix it before it cost more peoples lives. I just want what I paid for and I did not get that when I bought it with these types of issues.

The back sliding window on the drivers side exploded, sounded like a shot gun going off , I had started my truck with the key grabbed some thing to take with me pulled out of my driveway and it exploded , call The manufacturer went through a number of calls. They had a dealership do an inspection and Gm said not there issue , just had it replaced and it is immediately showed signs of overheating with discoloration and defroster lines breaking in the glass immediately after the vehicle got repaired. Certainly there is an issue that needed correction but can’t get the correct help.
