2018 CHEVROLET SILVERADO 1500 Recalls, Complaints & Safety

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'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.

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

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 contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle hesitated or shuddered while depressing the accelerator pedal. 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.

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

Odometer Fraud. The contact purchased a 2018 Chevrolet Silverado 1500. The contact discovered that there was a mileage discrepancy after the purchase. The vehicle was a private sale.

Torque converter failed which led to premature transmission failure at 115,000. Known common issue with 6L80 and TSB advising this. No recall

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?

shudder while driving

2018 6.2l engine dropped 3 lifters at just a little over 70k miles. Vehicle is my wife’s and almost caused her and my child to have an accident while traveling on highway at posted speed. Vehicle lost power that resulted from premature engine failure resulting in vehicle losing power to the brakes and steering while in heavy traffic. This directly affected my wife and immediately caused her to have a panic attack. Vehicle has always been maintained to the highest levels. This issue affects a substantial amount of these motors around the same mileage. Very bad and unsafe AFM design that is common among vehicles with this engine. Transmission is also experiencing studdering/vibration issues. Right now we have paid out over 5k for engine repairs. Transmission needs repaired and presents a constant safety risk to our family as well as others. GM needs to stand by their products as we consumers put our trust in these vehicles to be safe and to last more than a few miles. My wife and I both have to work and unfortunately we don’t have the extra funds to purchase another vehicle or to keep shelling money out to fix a basically new vehicle that we have babied. Please help us hold companies accountable for their failure to stand behind their products. Thank you for your time.

Number one electrical system left side wire harness manufacturer installed in properly, not watertight and ran through a pinch point causing wires to break. Safety was put at risk due to power failure from fuel pump and brake lights failing which could’ve caused a potential accident. Been confirmed by an independent service center. Reached out to the manufacturer. They said there was no recalls. It was very unhelpful. On the failure happened a light did come on. Number two media end navigation system this is a safety risk because at certain times it will switch between screens at will by itself. They will also put calls on hold, causing you to instinctively reach for your phone and taking your attention from driving as well as switch off of navigation moving your attention from driving, this is a clear definition of distraction and not serving the purpose it was created for which is also been confirmed by an independent shop. I reached out to GM. They said there was no recalls. And there is no service light. P.s.I just found out that I could make a complaint here so I do not have any of my old documentation. I just went to the dealership this morning to try and get some help and I had no luck. They would not be helpful at all. They just want to sign me up for a service meeting and charge me another $500 to look at it only to tell me they can’t order me a wearing harness again.

Safety restraint system light comes on regularly

My 2018 Silverado z71crew cab LT , 5.3L engine was having issues with hold Freon in AC unit. We took to dealer to be fixed in June 2025. They added Freon and it was running good for a week then once again blew but no cold air. So took back second time 7/3/25 and they started the die test and machine went down in middle of doing it. So could not finish fixing . We took back on 07/20/25 and they completed the test needed condenser . So few days later we took to our local mechanic to have the condenser replaced and all is well with the AC unit now. Everything was fine from mid July 2025 till Oct 14 th 2025 , when it started shaking and was running rough and engine light was on so I had it checked for codes to see what it needed. Came back as bad injector. So we took to local mechanic to have injector replaced and tuneup and coils replaced . After this was completed was running much rougher then before we even had that injector and tuneup done. So mechanic suggested for him to keep it and let him dive deeper into what was wrong and why it was running rougher than before, so we let him do that.. after two days, he came back and told us that there was a crack in the engine and that is why it was running rough and that it probably was going to have an engine failure and might be and must be replaced. So I looked up my VIN number to see if there’s any recalls for my particular truck and engine size which is a 5.3 L and it doesn’t show my particular truck but it does show my year of a Silverado and the 3.6 L engine has had the same issues so I was wondering if this recall should be extended to the 5.3 L 2018 seems to be the same problem with the engine block.

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.
