Filed May 22, 2026 · Engine · CA

While driving on highway with cruise control set at 65 mph, the engine started misfiring, lost power and multiple warning lights came on. This was the first and only time I had engine problems and I never had any warning lights come on prior to this incident. Dealer confirmed engine experienced complete failure and need to be replaced.

Vehicle info: 2019 Silverado 1500 6.2L engine with 66,xxx miles. On 3/1/26 While towing my small snowmobile trailer I was driving on I-90 with cruise control set at 65 mph. Very suddenly and shockingly I heard an extremely loud knocking noise from the engine. I then witnessed several driver info messages stating things like "low oil pressure" "engine power reduced" among others and a check engine light. Amongst freeway traffic and now under no engine power and coasting I made an emergency lane change out of the passing lane and into the right lane and subsequently on to the shoulder of the interstate. Oil pressure was also noted to be very low during these events. I called a friend to pick me up off the side of the freeway and also had a local towing company get my truck and trailer off the side of the highway asap. This was a dangerous scenario and could've ended much worse. The vehicle is now at my residence and I am not sure what steps to take right now. As I am very aware of the current recall on similar models with the same engine. I have followed the issues and complaints of these trucks and suvs with the L87 6.2L engine closely. I was under the impression that my vehicle was not included in the recall and I have always been very diligent about vehicle maintenance. I've been watching my truck closely for abnormal noises, power or oil pressure loss or any other strange symptoms I have not noticed any warning signs. I even recently switched to the new dexos approved 0w-40 engine oil that GM is recommending and/or mandating. This was very sudden and scary scenario. I do have video of the engine noises if theyre. Theyre not currently formatted for this report

Passenger side lifters have failed, along with camshaft. The induced misfire caused a sudden and potentially unsafe jerking of the vehicle while on the expressway. The vehicle was on cruise control and running at 1,400rpms at the time of the failure. There were zero warning lights or vibrations/noises that could have indicated an imminent failure. Thankfully I was alone on the expressway at the time of the incident as the vehicle started bucking, jerking me out of my lane until I could regain control. Vehicle had 105,500 miles with all engine maintenance up to date prior to incident. Speed limit on this section of US31 is 75mph.

While driving down the interstate on cruise control with my son, my truck dash board lit up with no warning, service esc, service parking brake, check engine light flashing. The cruise control was disengaged and did not function. The truck began to run very rough.small amounts of White smoke where visible from the tail pipe. Acceleration was very hesitant. The codes were scanned and showed misfire on cylinder 1 and a rough idle code. The repair shop confirmed I had two failed lifters that destroyed my camshaft and send metal throughout my engine. The repair was to replace the entire engine.

Vehicle is producing a hard shift between 1st & 2nd gear primarily on cold starts. More recently is has been doing more through out the day but not as serve. This started around 7500 miles, currently at 23,000+. The vehicle has now been to three dealers (6+ attempts) with no resolution. One dealer took the valve body off for inspection and cleaning. Other dealers have tried reprogramming. Last attempt at repair was the week 8/25/2020 with no resolution as they could not duplicate the issue (had the vehicle for a week). The next day I experienced the harsh shift twice in one day. I also experience transmission slippage at constant speeds between 45 & 60mph. A bulletin came out from gm the week of 8/25/2020 indicating note to repair/replace the transmission as this is normal. How is this normal when it shift so hard it through the occupants forward and rearward in the seat. How is this safe for a young child/toddler? This has the potential to cause whiplash in younger children. I have in firm believe this is a cause for my neck and shoulder pain. As an added note: I have been working with the gm executive resolution team on this issue and again no resolution. I am also experiencing an issue with the parking brake coming on by itself when the vehicle is completely off and the key out of the vehicle. Again dealers cannot duplicate even though one service rep witnessed it while dropping the vehicle off for service. This is a safety issue for anyone performing brake service as the brake could activate and cause a pinch point. Overall I have several other electrical issues regarding radio, dic display & cruise control. Only the dic display has been corrected. I also have had leaking rear slider and squeaks in the front left dash, right front floorboard and upper lh b-pillar. I also had the left dash panel replaced due to a broken tab. Video upon request

Pulling out of a gas station onto a highway my dash display showed "service power steering drive with care" I noticed I had no power assist to my steering and the steering was extremely hard to steer at best. I also received the message "service ecs" at this point I had little control of the direction the vehicle was going and managed to pull over. I also noticed the following functions stopped working, cruise control, traction control, lane assist, auto stop, etc. I let the vehicle sit about 20 minutes and restarted. No errors remained and I went on my way. Scary situation to be in on a highway.
