2018 CHEVROLET SILVERADO 1500 Complaints

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.
