2024 Chevrolet Tahoe Problems

While driving, my Chevrolet Tahoe suddenly developed a severe, rhythmic bottom-end engine knock, indicating a catastrophic internal mechanical failure. I immediately took the vehicle to an authorized Chevrolet dealership on May 29, 2026, for emergency diagnosis.The dealership technicians officially diagnosed the issue as a severe lower-end engine failure. They deemed the engine unrepairable and determined that a complete long-block engine replacement is required.As of today, July 6, 2026, the vehicle has been sitting at the dealership for over 5 weeks and has yet to be fixed. The prolonged delay and sudden mechanical failure present a severe safety hazard, leaving me without a vehicle due to known GM manufacturing defects currently under NHTSA investigation. This report is being filed to document the failure of the 6.2L engine lower end, the necessity of a full long-block replacement, and the ongoing repair delay.

On Saturday, April 25, 2026, I experienced engine failure on my 2024 Chevrolet Tahoe 6.2L V8. This was a very dangerous situation, and could of been potentially dangerous to others around me on the highway. There was no warning just complete loss of engine propulsion at highway speeds. It was towed to the dealership on this same date. On Monday, April 27, 2026, it was confirmed by the Chevrolet Dealership that this vehicle suffered catastrophic engine failure and that the engine was seized up. Inspection would be available upon request.

See attached document for complaint. We are writing to express our concerns regarding ongoing and unresolved issues with our 2024 Chevrolet Tahoe High Country Deluxe Package, which we purchased on [XXX] from Titus-Will Chevrolet in Olympia, Washington. Our vehicle was ordered on [XXX] and delivered with 12 miles on the odometer [XXX]. The total purchase price was $97,889.61. This vehicle is equipped with a 6.2-liter Ecotec VB engine and a 10-speed automatic transmission. Since shortly after purchase, we have experienced intermittent audio output problems. With these problems, there is no audio for the radio, phone calls or mapping directions from any of the apps. Incoming phone calls do not connect and outgoing calls cannot be made. Despite multiple service visits-[XXX] as well as documented audio output issues my wife recorded and dated due to the fact that the dealership is 50 miles away: [XXX] We have also driven our vehicle into the Titus Will dealership service department twice when the audio output was not working so the service techs were able to see exactly what was not working-the issues are still unresolved even after updates from the service department and over the air updates that were to "FIX" the issues per GMC/Chevrolet. Our dealership has been unable to identify or correct the defect. Additionally, we received a Safety Recall Notice (N252494000) on May 20, 2025, concerning a potential loss of propulsion in the 6.2-liter engine, which may lead to catastrophic engine failure and increased risk of a crash or harm. We were surprised to learn that this recall was issued on April 24, 2025-prior to our purchase date-yet was not disclosed by the dealer at the time of sale, which also appears to be deceitful on GMC's part. We would not have accepted the vehicle knowing there were catastrophic engine problems as we travel the highways often visiting family in Idaho and Spokane as well as taking care of our elderly parents this last year with their medical care transports. When we contacted Titus-Will Chevr

I have a 2024 Tahoe that was purchased new from the dealer and has 13,700mi. The first service was completed as required in December with no issues identified. Less than 2 months later the front wheels started making a squeaking sound intermittently when accelerating, coasting or breaking. There were no warning messages. The dealership/mechanic looked over the car & said that the front brakes were measuring 2mm (completely worn out) but no other issues. Before drop off the car computer said above 75% or more for front and rear breaks (green). I have been driving the car in normal condition in southern ca. It seems that the break pads were defective and degraded at an alarming/unsafe rate or that a different component on the car caused them the continuously rub and wear down. The dealership blamed it on owner operation even though they supposedly checked them 2 months before and didn't see abnormal signs of wear. I am very concerned with the QUALITY, RELIABILITY & SAFETY of the front breaking system due to the fact that the breaks wore out so fast. I am worried that the problem has not been properly identified and that that breaks will continue to have this problem if it wasn't caused by faulty pads. I have never had a break wear problem like this before on any of the other 5 new cars that I have owned. This is the first American brand car I have owned and hopefully it's not a sign of things to come.

My vehicle started having stuttering/shifting issues back in August 2025, I was advised the vehicle did not need new engine but upgraded oil. I continued to have the issues and have continued to bring back to dealer for constant software updates - cannot duplicate issue meanwhile the stop sale order was issued and I was not advised. The vehicle then experienced very hard jerking- stall- that lead to the dealership putting an AWD IN 2WD calling it a fix! Just got vehicle back again after a complete stall at a stop sign- causing vehicle to roll back and cut back on! Dealer stated the vehicle showed the stall/shutter but could not duplicate on road test. This is a serious safety issue!!

The contact owns a 2024 Chevrolet Tahoe. The contact stated that while driving approximately 55-60 MPH, the vehicle stalled. No warning lights were illuminated. The vehicle was taken to the local dealer 10 times and the dealer retrieved diagnostic trouble codes for the control module, body control module, rear parking assistance, loss of communication, and transmission solenoid. The vehicle was not repaired. While driving at an undisclosed speed, the vehicle shifted out of the intended gear and shifted into neutral. The vehicle then went into LIMP Mode. The manufacturer was contacted and opened a case. The failure mileage was approximately 30,837.

Vehicle lost all braking capability while in motion. Vehicle rolled to a stop with no brakes with warnings for brake system failure, no front collision active. Upon restarting the vehicle the warnings didnt not go way for 1hr. 2 hours later the warnings cleared from the information system but codes remains. Vehicle was taken to Uptown Chevrolet, Slinger WI and was informed of a bad battery as the "cause" of the issue. A bad battery should not result in the loss of braking capability on any vehicle!

BRAKES JUST GAVE OUT ALMOST HIT THE CAR INFRONT AND SWURVED TO AVOID IT THE CAR ALMOST HIS THE WALL AND ANOTHER CAR WHILE TRYING TO CORRECT MY TRUCK IN A PROPER LANE. Brake pedal went straight down to the bottom and let the truck coast to a stop. SCARED TO DEATH THANK NGOD I DIDN'T HIT OR CRASH !!!!

Went to my car during lunch at work, turned on but Car won’t crank up. screen says service steering column lock, front collision unavailable

On October 23 I was driving my vehicle and the airbag light and a message service safety restraint appeared. On October 24 I was in route to take the vehicle to the dealership and as I was merging going to the highway the vehicle turned off, lost complete power threw itself into neutral. I had to drive it over to the shoulder to keep from getting hit. I was able to get the vehicle to turn back on and got it to the dealership. This would be the third time that the vehicle has lost power and completely turned off while driving the first time I took it to the dealership. They said they couldn’t find anything wrong. The second time this happened. I took it to the dealership. They said they replaced the gateway module this third time I took it to the dealership they have called me and said they need to replace the OnStar telecommunication module. The vehicle is unsafe. It is a brand new 2024 Tahoe I purchased it new. The vehicle should not be turning off while I’m driving The same messages consistently pop up the airbag in the service safety restraint. They replaced some kind of console at the top and say that that would fix the issue, but it didn’t because the message came back on again the vehicle idols as if it’s gonna turn off whenever I go to stop the vehicle The transmission stutters are like it’s going into a downshift and it acts like he wants to turn off, but it doesn’t it’s only turned off when I’m driving and then it will just shut off.

I was in a rollover crash on 3/9/25. I hit the guardrail head on, then completely rolled the vehicle multiple times. The driver/steering wheel airbag did NOT deploy. Curtain airbags, and the airbag from the seat deployed but the steering wheel did NOT. My head hit the steering wheel as a result with injuries to my face. The airbag malfunction was confirmed by a mechanic.

I am reporting a serious safety concern involving a 2024 Chevrolet Tahoe with approximately 23,000 miles.I have a video recording of it . While the vehicle was being driven, water suddenly began actively dripping from the rear cabin light/headliner area into the interior of the vehicle. There were children inside the vehicle at the time, including a child seated directly underneath the area where the water was dripping near the child seat. A significant amount of water is entering the vehicle and continues dripping throughout the interior cabin area. The water appears to be coming from the upper rear cabin/light area and may have entered the electrical system or interior electronic components of the vehicle. I am extremely concerned about potential electrical hazards, safety risks, corrosion, and malfunction of electronic systems caused by water intrusion inside the vehicle. This vehicle has relatively low mileage for its age and has not been modified. The condition appears to involve a possible manufacturing, sealing, or drainage defect. Because children are transported in this vehicle daily, I believe this issue presents a serious potential safety concern and should be formally investigated.

Front passenger wheel has a fracture. The structural integrity of the wheel is compromised and is causing the tire to leak air, which is dangerous and can cause loss of vehicle control and damage to suspension or brakes. It could also cause dangerous blowouts, which causes a safety concern for me and others on the road if that happens. The problem has been confirmed by the dealership where the vehicle was purchased. Photos were taken and submitted to GM for warranty. The warranty was denied. The vehicle has not been inspected by anyone else other than the dealership where the vehicle was purchased. The only warning lamps were low tire pressure warning. The fracture was found during inspection as to the cause of the low tire pressure.

While driving at night in the rain. The front windshield wipers paused in an upright position for 3-5 seconds and all exterior illumination/lighting went out. They all came back momentarily.

After start up, there is no audio coming from the vehicle. No audio from entertainment system, no audio from turn signal and no audio from fasten seat belt "chime". Restarting vehicle does not change the outcomes, initially. Exiting the vehicle and restarting about 10 minutes later, all audio returns, including entertainment sytem, audible turn signal indicator and fasten seat belt chime (if seat belt is not engaged). This has occured on several occasions since about 11/1/2024.
