The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated.

Passenger side Upper control arm broke in two about to re-enter I75. Had been on I 75 and was going back on it when handling went wonky on Service road. You can see from the rust in the break this stamped part was cracked a while. Vehicle has not hit or run over anything since I have owned it. Had I been on I75 at highway speed it would have been deadly.

This 2108 vehicle had 56174 miles on it in October 2023 when the starter went bad, then with 56382 miles on it in November 2023 the lifter failed and the engine had to be replaced and then with on 56838 miles on it in Dec 2023 the engine light came on and the dealership replaced the canister and solenoid. All in a 3 month time. Chevy says it happens. Then we start reading it is a problem with their 2019 to 2024 vehicles. Maybe it goes back more.

In May 2023, my 2018 Chevrolet Silverado 1500 with the 6.2L V8 engine experienced a catastrophic engine failure at 82,986 miles. The failure involved the camshaft, lifters, oil pump, and other internal components. I paid $7,319.63 out of pocket to have the engine disassembled and repaired by a certified mechanic. I recently learned GM issued a recall (NHTSA Recall No. 24V266) for 2021–2024 vehicles with the same engine due to internal engine failures caused by crankshaft and rod bearing defects. Although my 2018 model isn’t included, the failure I experienced closely mirrors the conditions cited in that recall. I believe the same defect may exist in earlier models like mine. I’m submitting this complaint to urge NHTSA to consider whether the recall should be expanded to include additional affected years.

At 25,000 miles, noticed "howling" noise coming from front end. Noise became louder as speeds increased. Lifted truck on jacks and determined the front passenger wheel bearing was failing. Required replacement.

Hard shift when transmission is shifting around 70 mph and also transmission temperature keeps rising above 230 degrees. Shuddering when shifting after city driving.

The engine/ transmission has been rebuilt 3 times now and still having issues. The RPM goes up out of nowhere. Something is wrong with the truck. I have taken it to my mechanic over 10 times in the past year. It is still having transmission issues even after being repaired 3 times by a transmission shop.

I well maintained my 2018 Chevrolet Silverado, and now the motoer is failing, loss of power and just started smoking from exhaust, my mechanic said that the motor is in the process of blowing up. I made every oil change, and maintained the vehicle because I wanted it to last and be the last vehicle I had to purchase. It failing almost caused a bad accident on the interstate, but luckily I was able to avoid an incident and get to safety.
