While driving home late at night, the vehicle experienced a sudden mechanical failure in the engine. I was traveling approximately 2 miles per hour while slowing to stop at a stop sign when there was a loud “clunk,” followed by an abrupt stop of the vehicle. Immediately after this occurred, multiple dashboard warning lights illuminated, and a knocking sound began coming from the engine. The vehicle is currently not operating normally and is available for inspection upon request. This incident occurred late at night while I was driving with my two young children in the vehicle. The sudden and unexpected stop put us at risk of being rear-ended or stranded in an unsafe location. The loss of normal vehicle operation created a dangerous situation, especially given the time of night, location, and the presence of my children. There were no warning lights, messages, or noticeable symptoms prior to the incident. All warning lights illuminated only after the loud clunk and abrupt stop occur

2021 tahoe with 3.0L diesel engine and 139k miles recently began overheating when on interstate but temp would jump up quickly then quickly back down. Reduced acceleration mode is triggered and AC is turned off automatically. Diagnostic report shows coolant control valve error code and it was explained to me that valve is sticking then as engine pressure rises, it knocks it loose again explaining the quickly jumps and dips in temp. Fan runs constantly from moment it is started too. When looking for the part online to get an idea of repair cost, there was a bulletin about this being a known issue in the 2021 tahoes with the diesel engines and bulletin states GM extended special coverage for 15yrs/150k miles. When I called dealer to schedule service, I was told this bulletin doesnt come up under my vin number despite it having the same issues, error codes, year, make, model, and engine.

The vehicle stalled while driving down the road and started making a loud ticking noise, the engine light went on. It was brough to the dealership where they did an engine rebuild. They replaced 16 lifters and camshaft, a pulley belt and gaskets. The vehicle was picked up, however, a month later the oil low add oil light came on and the oil tank was more than 2.5 quarts low indicating extreme burning of oil. The vehicle is shuttering on acceleration of low RPMs. Brought it back to the dealership and awaiting further instruction. It caused a major safety concern because it has the potential to stall due to a motor defect on a major highway, putting my family and possibly others at risk of harm or death.

Lost Power. Engine went into a limp mode. Engine starting knocking loudly and service esc came up on dash along with check engine light. Took it to the dealer and they said a lifter spun and damaged the camshaft. Dealer says it’s not covered by recall. Vehicle has been in Chevy dealer garage for 2 weeks and no repair yet.

While driving normally, the vehicle developed engine performance issues and was diagnosed with a catastrophic camshaft failure at approximately 85,000 miles. The vehicle has received regular oil changes with full documentation and has not been abused or neglected. A licensed mechanic confirmed that the camshaft was severely worn and damaged, consistent with AFM/DFM lifter failure, which is a known issue on GM V8 engines. This failure caused significant internal engine damage requiring major repair. The failed camshaft has been retained as physical evidence. A camshaft should not fail prematurely under proper maintenance. This appears to be a manufacturing or design defect, not normal wear and tear, and presents a potential safety concern due to sudden loss of engine power.

Electric Power Steering system issue after battery died and had to be jump started.

I was driving down a busy road with my toddler in the car when the car just stopped. Went from traveling 40 mph to a complete standstill. Dead, in the middle of the road. No warning lights or signals at all. Could not get the car in neutral. Wheels locked up and not able to shift to neutral without the car being on, which was not happening. Had to get the car towed to the dealer. The tow truck driver had to drag the car on to the truck. No getting the car in neutral at all. Dealer diagnosed the problem as the fuel pump control module, which after researching is a major problem for this make/model/year. Should most definitely be a recall that has to be remedied by the manufacturer as this is not safe at all. Could have easily been hit due to traveling at a normal speed to stopping so suddenly. Then on top of it, not being able to get in to neutral to get to a safe location out of traffic.
