Chevrolet Tahoe grinding brakes problems

Filed Oct 21, 2026 · Engine · TX

At approximately 80,700 miles, I started my 2019 Chevrolet Tahoe (6.2L V8) to take my family on errands. My wife heard a squeaking noise from the engine as she walked to the vehicle, and I got out and heard the same noise. No warning lights or messages appeared on the dashboard, before or after. I took the vehicle to an independent repair shop, expecting a belt problem. After inspection, the shop told me the valve lifters had failed and needed replacement, and that the camshaft would likely need replacement as well. I declined the repair and took the vehicle to a GM dealership for inspection and documentation. The GM dealer confirmed the lifters need replacement. They could not confirm whether the camshaft is also damaged without an engine tear down, which I have not authorized. The dealer estimated $13,200 to replace the lifters and camshaft. The independent shop estimated $8,200. The vehicle has not been repaired, and the failed components are still in the engine and available for inspection. I am concerned for my family’s safety. Lifter failure on this engine can cause misfires, loss of power or engine failure while driving. We use this vehicle to transport our family, and a sudden loss of power on the road could cause a crash.

Brake System Failure 62 MPH Top Speed Service ESC Service Brake Trailer System These warnings appeared on 04/30 and my brakes became extremely hard to use to stop my vehicle. I had my two young children in the car, I was able to go up hill and shift it into park after driving 15 minutes basically with no brakes. It was towed to Hendrick Chevrolet, where they replaced the master cylinder. On May 5th I was driving the car and the service brake assist light came on with the message. I then had it towed to Hendrick where it stayed until July 28th. The dealership stated that it was an external leak in the master cylinder. Now for the 3rd time the brakes are making a squealing noise and the service brake assist light is on again. I do not feel safe in this vehicle.

My 2023 Chevrolet Tahoe (VIN: [XXX]) suffered a catastrophic failure of the 6.2L V8 L87 engine assembly — specifically the connecting rod and crankshaft components — at freeway speeds on [XXX], just 9 days after purchase. The original failed engine is no longer available for inspection as it was removed and returned as a core by Shaheen Chevrolet in Lansing, MI as part of the warranty replacement process. The only symptom prior to failure was a brief squeaking noise that began approximately 0.5 miles before the engine failed. No warning lamps, messages, or other indicators appeared at any point before the failure. The engine then failed suddenly and completely at freeway speed, causing immediate loss of propulsion. My family was left stranded in an unsafe roadside location until a tow truck arrived. Sudden loss of power at freeway speeds creates significant risk of collision for both the vehicle's occupants and surrounding motorists. The failure was inspected and confirmed by Shaheen Chevrolet as a GM manufacturing defect involving the connecting rod and crankshaft. No police, insurance representatives, or GM field engineers inspected the vehicle beyond the dealership. GM authorized a full engine replacement under Special Coverage warranty (10 years/150,000 miles). The replacement engine (GM part #12740076) was on national backorder for over two months due to supplier capacity constraints. A loaner vehicle was provided during that time. This failure occurred despite a prior GM recall addressing the same rod/crankshaft defect having been performed on this vehicle. The recall remedy was ineffective. I have no confidence the replacement engine will not fail again. With approximately 597,630 vehicles affected, this represents a serious and ongoing public safety risk.

My 2025 Chevrolet Tahoe RST Performance Edition equipped with the 6.2-liter V8 experienced a catastrophic engine failure at approximately 28,400 miles. The Tahoe was towed to an authorized Chevrolet dealership. The dealer confirmed an internal engine failure requiring complete engine replacement. The vehicle and failed engine are currently at the dealership in Lawrence, Kansas, and should be available for inspection upon request. The precise internal cause has not yet been provided to me in writing. I was advised that obtaining and installing the replacement engine is expected to take approximately 60 to 90 days or longer. The scheduled 30,000-mile maintenance was performed by the Chevrolet dealership on June 29, 2026, when the odometer read 27,607 miles. The engine failed less than two weeks later, after approximately 800 additional miles. Two days before the failure, I noticed a knocking or ticking sound from the engine. Immediately before the failure, I heard loud squeaking or screeching followed by a severe metallic clanking sound, as though loose metal components were being thrown around inside the engine. The engine then shut off and the vehicle became immobilized in Park at an intersection. I was the first vehicle in a left-turn lane and could not shift the Tahoe into Neutral to push or coast it out of the roadway. Heavy traffic turning toward the highway was forced to maneuver around the disabled vehicle, creating a significant risk of a collision. The outside temperature was approximately 95 degrees, with a heat index of approximately 109 degrees. My dog was with me, and it took more than an hour to arrange transportation for him to a safe location before I could return to the disabled vehicle and continue waiting for the tow truck.

I have been having issues with the brakes on my 2016 Chevy Tahoe for as long as I can remember. When going very slow, such as in a parking lot or pulling into a parking space, my car feels like I am driving on ice when I brake. I am not sure if I am actually going to stop or hit a car/person. The brake pedal also gets very hard. It makes a squeaking sound and also sounds "airy". It is an intermittent problem and does not happen every single time I press on the brakes when going slow. I received a recall notice back in 2019 for increased brake pedal effort and the dealer reprogrammed something. This however, ultimately did not fix the issue and I have never received any follow up information or recall alerts pertaining to this issue. I have mentioned this a few times to both the dealership and an independent mechanic in the last 6+ years, but the car never has the issue when it is in for service. I was told the last 2 times that I took my car in for service that I needed new brake pads and rotors. so both have been replaced twice in the last 4 years. The issue with the brake pedal happened again the other day, only this time, I received a warning message to service brake assist and I smelled what I can only describe as burning brake dust. I also noticed what looks like brake dust on the floor of my garage. I was once again irritated and decided to start googling and that is when I found a special coverage warranty on GM's site for the exact issue I have been having all of these years. The warranty expires December 15, 2026 or at 150211 miles. I called the dealership and GM to see if they would honor the warranty since I only had 150,350 miles on my car, however they both said no. What can I do? I guess they would rather I hit and injure someone than fix an issue they are obviously aware of? Why was I never notified that there was a special coverage warranty on my car? When these incidents occur it is scary and poses a danger to both myself and others.

I was on the interstate. Initially I heard a faint rattling sound. I turned off the radio and AC to listen more closely; the sound was not audible. But then traffic came to a standstill. As I slowed, that barely audible noise began to sound like something boiling in the engine. The temperature and pressure gages were all in normal operating ranges. I pulled to the shoulder of the interstate and checked under the hood. I noticed a distinctive squeaking sound although the fan belt was intacted in running true. There was no sign of any fluid loss in the engine compartment or underneath the vehicle. While attempting to get to a Chevrolet Dealership one exit away, the vehicle stopped running while at a stop light. additionally, there is a recall on this vehicle for the automatic braking system. GM and the dealerships are aware of this recall yet this website states there are no recalls.
