2018 Chevrolet Silverado Complaint Log

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.

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.

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.

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.

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 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.

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.

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.

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.

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 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.

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.

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 representative also declined to open a case. There were no warning lamps or dashboard messages prior to discovery, as frame corrosion is not monitored by vehicle systems. The defect was identified visually during state safety inspection. I am requesting that NHTSA investigate this defect pattern and consider a recall, as was ultimately ordered for the similar frame corrosion defect on Toyota Tacoma trucks.

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.

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.

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.

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'm not seeking full payment; I even mentioned Goodwill assistance of which they denied; however, I'm without a vehicle and have received very little to no communication in resolving this issue, which is an issue I'm finding is happening to many others alike and General Motors Corp, is not taking any responsibility or accountability in this matter.

Transmission skips 1st gear and jumps and shakes vibrates. The transmission has to have a total rebuild

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving approximately 40 MPH, the low oil warning light illuminated. The vehicle was taken to Pepboys, and the contact was informed that the engine was a quart and a half low on engine oil. The mechanic determined that a gasket was deteriorating, and the seal had fractured, causing the oil leak. The vehicle was taken to the dealer, and the contact was informed that the engine and transmission needed to be removed to replace the gasket. The vehicle was not repaired. The manufacturer was informed of the failure and confirmed the repair was not covered under warranty. The manufacturer opened a case for the failure. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 84,000.

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.

-Transmission failed. - Driving down the highway and the truck just quit. (Morning rush hour traffic) -truck was towed to my mechanic -only made a weird noise the day before.

Collapsible lifter and lift rod failure

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.

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.

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.

My transmission blew up and I almost wrecked my truck. No engine lights came on, and still no engine lights are coming on it only has 69,000 miles on it and has never missed a service. Its currently at the dealership where I bought it from

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.

Crotch buckle belt is frayed and no longer safe to use. this should not fall under the umbrella of normal wear and tear since it is a safety strap. Nuna claimed it to be caused by a rodent, but there is no other evidence or signs of any other rodent activity

Since purchase in 2018, my pickup truck has had a ticking and banging sound which includes rough idling and a check engine light. During routine maintenance, oil changes, etc. I have continued to ask about the noise but GM technicians have said nothing is wrong. In November 2025, i took the truck to a local shop for an oil change and that’s when I learned it has lifter issues. Upon investigating whether other Chevy Silverado truck owners are experiencing the same thing, I’ve learned about various recall and extended warranty programs offered by General Motors. I’m wondering when or if my 2018 Chevy Silverado might be included in a recall or could i be offered an extended warranty?

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

Truck was intermittently losing power steering and shutting off/reseting itself. Was a loss of electrical and was throwing Stabilitrak Service warning. Would not stay on due to truck resetting itself but loss of power happened typically when I was in parking lot or driveway. Could have easily been on the highway which could have been deadly. Dealership found that the battery cables and module were not getting enough power to truck. Replaced these and it seems okay now. Total cost was ~$1200. I see several recalls for battery cable issues but nothing pulling on my 2018 Chevrolet Silverado 1500 LTZ crew cab.

When attempting to stop, the brakes were rock hard and would barley compress. Almost crashed into the car in front of me. Brake booster was replaced a month ago by dealer, but still is losing vacuum. No codes are being thrown, so any reasonable driver would assume everything is fine with the vehicle. It is going to get someone killed.

2018 Chevy Silverado with 84,000 miles and the transmission is broken. Truck is currently in a shop to have a new transmission installed.
