We were driving on the highway and the engine started making a ticking noise and AFM light came on. Took the car to the dealership for inspection and they said the lifter had collapsed and it would cost $1000 to tear the engine down to see if the camshaft was damaged. Asked for the estimate to replace camshaft and lifters and they quoted $10,000.

We purchase the vehicle in February of 26’. Certified preowned they a Chevrolet dealership. It was disclosed to us that the engine had been recalled and replaced in September of 25’ (had about 1500 miles put on it, before we bought it) due to the ongoing issues that plague the V8 6.2L motors. We put less than 3000 miles on the vehicle and wanted to take it in for oil change and new tires. My wife had heard a rattling/ticking sound and wanted the dealership’s service department to check it out. They test drove the vehicle and immediately told us that this second engine needed to be replaced with less than 4,500 miles on it. We’ve now had a loaner for almost 7 weeks while we wait for a new 6.2 liter engine that no one is even sure won’t have the same thing happen to it that the first two engines had happen. GM needs to correct this issue. I read that over 1100 6.2 liter engines are on back order. This is unacceptable.

I asked the dealer for information about the L87 6.2L engine rod bearing failure recall. I was told that they wouldnt perform the work until i recieved a letter from GM. This was when i got my first oil change. Then every oil change after that i asked the same question. At 43401 miles i parked the vehicle and havent driven it since. I am afraid to have something happen to me or my family. I paid $82,000.00 for a vehicle that GM's fix is to add thicker oil. I think that the rods and bearings should at least be visually inspected. The dealers maintenance manager at Kunes Lake Geneva says theyll listen to it with a stethescope. If it sounds ok theyll change the oil. I paid way to much to chance my familys safety on thicker oil. To make the situation better the vehicle blue books for $56,000.00 IT DEPRECIATED $26000.00 IN TWO YEARS. That is unacceptable.

I bought this 2023 Chevy Tahoe rst brand new from the dealer and about a few months of owning it I noticed that the truck was needing oil before the next oil change. It’s as if it was consuming itself. This continues for month until last week when the truck died on me. I was able to jump start and everything worked fine for a day. The next day things got worse. I was on the highway and truck started shaking and giving off all kinds of codes. I took it to dealer and they said I needed a new battery but that there was also an engine problem. I bought a new battery and none of the messages on dash resolved like I was told. The truck is u drivable motor is knocking and was even making loud popping sounds. Of course my truck just hit 64,000 miles so gm is saying I’m out of warranty. I should not be having these types of issues on an almost brand new truck that I’ve owned 2 years. Engine light is flashing and dealer said this means major issue.

on [XXX] we bought our 2023 Tahoe High Country from Jeff Gordon Cheverolet in Wilmington NC. In April 2025 a recall was announced on our car for engine failure. In June of 2025 we received a letter stating that a fix for the recall was to have an inspection done. If passed, then an oil change and new cap would be done. This was completed. on [XXX], I was on the highway accelerating to get up the speed, when I heard a loud pop noise. Then i heard loud knocking coming from my engine, the check engine light came on with the traction light as well. The car then had sluggish acceleration and would not accelerate but would have high than normal RPMS and rev when trying to accelerate. I knew then that I had engine failure. I was able to get the car to a safe place and called the dealership right away. They got it towed to Marine Chevy since it was closer. The next day they did an inspection on the vehicle and said the camshaft and lifters were broken and had to be replaced. I said I would need a new engine replaced due to the damage and recall. I was told it would not be under recall because it was the top and not bottom. They said the GM refused the new engine but would not tell me if it was the General Manager or General Motors that refused. I called and texted multiple times asking for pictures. They refused to send me any until 9/9 after multiple attempts. They only sent me one of the rods and rocker arms showing a rod bent and stated it was the lifters. still no pictures of the camshaft broke or lifters. These problems already have multiple class action lawsuits out for this particular engine failure. I was told the recall would still be on the engine even after the repair, I can still have engine failure. I refuse to pay the money for this car to continue to be in the shop due to a bad engine that was put in these models. I also have a case open with General Motors for replacing the engine as well and they are refusing to help. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552

Started having an issue a few weeks ago with the vehicle shutting off while driving for no reason without warning causing a very serious safety concern. This issue seemed to stop until one Saturday when i started the vehicle i noticed a small tick. This ticking sound continued to grow. The vehicle then shut off again with warning while driving. 7 days had gone by since the first episode. When I started the vehicle again there was a very pronounce rapping and it sounded like parts inside the motor were coming apart. When I arrived home i called Onstar. They did a diagnostic twice and said the motor was not showing any codes and running perfect. I had it towed from my house and upon inspection the motor is blown with 10,000 miles

Engine failure due to rod bearing failure, without warning at 16,500k miles. It is available for inspection if needed. Currently is at dealership waiting for new engine. The vehicle shut off while driving at 40mph forcing me to have to stop in the middle of a roadway without any shoulders or turn offs. The problem was diagnosed and confirmed by a certified Chevrolet dealership. The failed engine will be sent to GM by the dealer. There were no warning lights prior to this incident or after.

On Sunday January 12, I was driving the vehicle on the highway with my cruise control on. The engine started missing the speed dropped a bit as the cruise control would not hold the speed. A mile or so later the vehicle engine started knocking with a metallic sound. I pulled over at the next exit and stopped at a store to look at the engine. There was nothing loose and a deep metallic knocking coming from the engine block, so I shut off the vehicle and called OnStar. At no time did any warning lights or other indicators come on. The gauges were normal. They/OnStar indicated I should not drive the vehicle, and they will tow to nearest Chevy Dealer for service and give me a $50 credit to take a Lyft to local airport to get a rental car. I was almost 4 hours away from home as I was travelling. After a week of turmoil with the local dealership I was told the vehicle needs a new engine. There is no ETA on the new engine as GM has to build it and has parts shortages. This was 5 weeks ago. I have been driving a rental since and there is still no indicate from the dealership about what happened or why. The vehicle is a 2023 and still under warranty but I am having to pay for the rental and request reimbursement which hasn't happened to date. There is very little information available, and I am in no man's land without a vehicle, so I have an open ended rental situation.
