ENGINE

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

FUEL/PROPULSION SYSTEM

My 2021 Chevrolet Tahoe suddenly shaked and the engine shut off and on and nearly stalled on the road. I towed the car to the servicing dealer who has not been able to fix the issue. There is a national recall for the issue for the month of September 2021 Safety recall N212332040 for this issue but NHTSA has not added my car. NHTSA must include my car with the same issue and built in during the same month of the recall. The safety issue is the car will stop running and may block traffic or can be hit when it breaks down.

We just recently had the cam shaft and lifters replaced, as the vehicle began experiencing a knocking sound. The repair was supposedly completed, and they gave the truck back. We took the truck back in within a week, bc we continued to hear the sound. They sent it back saying they didn’t hear anything after test driving it. Over the weekend the car shut off after beginning to shake uncontrollably. Now supposedly the camshaft bearing is gone, and the truck experience engine failure. I spoke with someone previously, as the issue being repaired hundred thousands of cars were recalled for the same issue. I was told that it wasn’t on the same line, even though my truck was experiencing the EXACT issue and fell under the years. We were placed back on the road with our family, with a vehicle

I have a 2021 Tahoe that while circling a parking lot at my son's football practice. The Tahoe's emergency came on and the Tahoe abruptly stopped. A checked engine light came on. The Tahoe wouldn't release the emergency brakes. I was finally able to get it released. I took the vehicle to a transmission shop because I plugged OBD scan tool on it. It had two transmission codes. One generic and one for the vavle body. The transmission shop said they have had lots of Tahoes with the vavle body's going out. They told me about N242454441. I called Chevrolet and they advised me that wasn't for my Tahoe. I asked why and they said they don't know. If this is effecting the desiel only models then why is mine doing the same thing. Parts cant be ordered either. Please look into this matter.

When i asked Kunez Lake Geneva, Wi. When the engine recall would be taken care of. I was told that GMC has to order the recall first. Then when asking about the process of inspecting. They informed me they would listen to the motor and decide if it was effected or not. I paid $82k for this vehicle. I find that listening to the motor isnt a thorough way of inspection. After they deem the motor ok. There going to put higher viscosity oil & an oil cap. What if something happens in the future. Is my familys life safety not important? Summary General Motors has decided that a defect which relates to motor vehicle safety may exist in certain 2021 – 2024 model year Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, and GMC Sierra 1500, Yukon, and Yukon XL vehicles equipped with the 6.2L V8 gas engine (RPO L87). The connecting rod and/or crankshaft engine components in these vehicles may have manufacturing defects that can lead to engine damage and engine failure. Safety Risk If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. Remedy Dealers will inspect and, as necessary, replace the engine. Vehicles that pass inspection will be provided a higher viscosity oil, which will also require a new oil fill cap, an oil filter replacement, and an owner’s manual insert.

VISIBILITY/WIPER

Wipers failed during heavy rain in heavy traffic on 7/3/25. Wipers randomly started working. The wipers failed again during a heavy rain on 8/13/25 again in moderate traffic. Wipers failed during heavy rain, was unable to see while driving on an Interstate.
