I am reporting a potential safety defect involving my 2019 Chevrolet Silverado 1500 Z71 Trail Boss (VIN [XXX]), currently at approximately 63,000 miles. My truck suddenly developed a rough idle, engine ticking, and a cylinder 3 misfire. The check engine, traction control, parking brake, and “Service ESC” warnings appeared. The transmission also began shifting extremely hard, at times feeling as though another vehicle had struck the truck from behind. The oil pressure gauge also stopped functioning. Due to these symptoms, I stopped driving the vehicle. A diagnostic scan produced P0303, P0449, P0498, P0499 and P0500. After replacing a failed cylinder 3 spark plug, the truck initially ran perfectly for approximately 20 minutes before the rough idle and warning lights returned. The vehicle was subsequently diagnosed by a Chevrolet dealership. The dealership determined that the engine suffered a collapsed lifter that damaged the camshaft and other internal engine components. The engine repair estimate is approximately $10,000–$12,000. The dealership has also reported that the transmission is slipping and believes the torque converter/transmission requires approximately another $6,300 in repairs. I am concerned that a lifter/DFM-related failure causing a misfire, rough running and potential loss of engine power could occur while a vehicle is traveling at highway speed and create a significant safety hazard. The severe transmission shifting and subsequent slipping are also concerning because unexpected vehicle behavior during acceleration or while in traffic could increase the risk of a crash. The truck has been regularly maintained and has relatively low mileage for its age. I am requesting that the federal safety agency review whether similar engine/lifter/DFM and related powertrain failures represent a broader safety defect and whether an investigation or recall is warranted.

Vehicle lost power assist to steering without warning.Very difficult to drive vehicle safely once that happened

Filed Jul 31, 2026 · Engine · FL

I was driving the vehicle and suddenly there was a loss of power and a ticking noise. I was up to date with my oil changes per dealer recommendations. Had the vehicle towed to to Chevy dealer and they said they weren’t able to find what the problem is without further diagnosing. Further diagnosing was estimated to be about $2500. I had it towed to an independent shop, Viking Motorsports, to which the owner/mechanic tore down the engine and deemed it as bearing failure in my 6.2 L87. There was no warning whatsoever, just went from running to engine dead immediately. I proceeded to an engine change that has costed me approximately $15,000 and would like full reimbursement if not partial reimbursement from GM given that this is a known issue for the problem. I did not go with the Chevy Dealership for the job since they quoted me $20,000+ for the engine swap and realistically that wouldn’t make financial sense. I have a High Country and at 102,000 miles when the engine has failed. This has put me in such a financial bind.

Wife was driving on the interstate when the vehicle revved up and then a loss of power. had to drive home while vehicle was popping and still loss of power. I took to an Independent Service Center, and they started a tune up with changing plugs. They checked vehicle and advised that it was possibly a lifter failure, but they couldn't fix it. I took to another independent service person and after a diagnostic check and looking into the engine it was confirmed it was a lifter issue. Vehicle has been in the shop for 3 weeks waiting on parts.

Without prior warning my power steering went out. This could have been life threatening. I had to have it towed to the dealership (Voss Chevy, Centerville OH). The truck had 66,552 miles on it and the extended warranty that we purchased thru Voss expired on 26 Mar 2026 and although we were under the 75K mileage, they would not honor it (planned obsolescence?) So they replaced the steering gear for $2183. After researching, the literature says that diagnostic code C1599 (which is what Voss saw) indicated that the steering rack is completely fine mechanically but it has simply lost its electrical connection. In addition, literature says that a steering rack should last at least to 100K miles. There are also multiple issues documented on carcomplaints.com regarding the loss of power steering. Perhaps a recall is needed. In addition, I believe we were mislead as to what repairs were needed.
