2024 Chevrolet Tahoe Engine 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.

The contact owns a 2024 Chevrolet Tahoe. The contact stated that while driving at 76 MPH, the vehicle was driving abnormally rough. The RPM increased, and the message to shut-off engine and restart the vehicle was displayed. The contact stated that the failure occurred while the two minor children and their friends were inside the vehicle. The contact's daughter stated that the vehicle was in neutral after leaving the car wash. In addition, the failure occurred while driving on a busy two-lane highway. The vehicle was almost involved in a crash twice when the engine seized in the middle of the left lane. The contact stated that while attempting to drive the vehicle to the shoulder of the road, the engine seized. The contact stated that while attempting to start the vehicle, the vehicle failed to restart. The local Police assisted with traffic control. The vehicle was towed to the dealer; however, the failure was not duplicated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The dealer was informed that the Mobile App indicated a transmission and engine failure. The dealer informed the contact that because the engine seized, the engine needed to be replaced. The dealer informed the contact that there was no indication of what caused the engine to seize. The manufacturer was made aware of the failure but provided no assistance. The contact referenced an unknown recall with a similar description; however, the VIN was not associated with the unknown recall. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 16,988.

Dealer checked the 6.2L motor for known defects. It "passed" inspection on 11/20/25 and got the thicker oil (OW-40). The engine lost propulsion ("died") 3 times on a 55mph State Highway on 02/09/26 with my 4 year old in the car with me. It died and came to a complete stop in one lane and would not re-start initially with cars almost rear ending us and needing to aggressively swerve to avoid hitting us. After 4 or 5 attempts it started again (making terrible grinding noises) so I could get it off the road before it died again. It started again to drive home on the back roads approximately 1 mile. Low oil pressure and check engine lights came on. I also received notifications from onstar and from the my Chevy app that there were severe motor or transmission problems. I scanned it with an OBD II Scanner and it has code P00016 (Camshaft Position Correlation - Bank 1 Sensor A). It got towed to the dealer and is now confirmed it is in need of a full motor replacement less than 3 months after they told me the motor passed inspection! This is not acceptable. To be told it's fine and then have it fail with my child in the car is extremely unsafe. Now I'm stuck trying to get a comparable loaner vehicle from the dealer to drive in the snow and mountains with my family safely while they expect to have the vehicle at minimum of 6 weeks. So far they have not found a loaner potentially putting my family in further danger by not having a 4X4 vehicle in a snowy climate.

The vehicle in question had approximately 5000 miles when low oil light came on, it was 2 quarts low. this was after the first oil change at around 3500 miles. I had the dealer do an oil consumption evaluation. They check the oil every 500 miles and confirmed it was using 2 quarts every 2500 miles. They informed me GM says this is normal. I cannot disagree more with that claim. GM knows they have a problem with the 6.2-liter engine. I have researched the issue and found they have a problem with the crankshaft machining and the oil delivery port beveling that delivers lubrication to the connecting rod bearing appears to be too large that causes the motor oil not to consistently keep the bearing lubricated. This causes the engine to be an "oil burner" and premature failure of the bearing. They think putting a heavier viscosity of oil in will delay the inevitable engine failure, which makes me believe they are aware of the faulty manufacturing and want to run from their warranty responsibilities.

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.

Purchased new vehicle in September 2024, immediately after purchasing the vehicle the engine had a clanking noise. Took the car back to the dealership where they explained the noise was normal. The car continue to make clanking noise, but noise continued to get louder, took the vehicle back to the dealership for first oil change, verify the noise, and discuss safety recall received on the vehicle. Dealer told me the car was ok to drive. In October 2025, the vehicle loss power during acceleration with immediate re-start. After this incident, took the vehicle to another dealer where they inspected the vehicle again. The test failed and the car now needs a new engine. Car has now 10K miles in the odometer and has been sitting in the dealership for 3 weeks now waiting for an engine replacement.

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.

Low Oil Life notification on phone. Since L87 recall, an oil consumption test was stopped and the new type of oil has been added to the vehicle 5k miles ago. Had to add a full quart to register on dip stick. Will now start another oil consumption test with a dealership. I am very concerned about my families safety.

Driving at highway speeds 70mph, the engine stopped running and vehicle lost all power during heavy rush hour traffic. I was in the middle lane and lost all power breaks and steering, the engine wouldn't restart and I had to force my way to the side of the road. The vehicle only has 21,709 miles and was purchased new less than a year ago. All scheduled maintenance has been performed. The engine is seized and will not restart. There were no warning signs.

When driving on the highway at 75 mph, my vehicle alerted me to add oil. We immediately pulled off the side of the road checked the oil. There was not even a drop on the dip stick. Had to add 3 quarts of oil to even register on the very tip of the dip stick. Please note we were within 100 miles of being due for an oil change. The vehicle is currently at a Chevy dealership to start the process of inspection and do an oil consumption test. This vehicle is my main transportation to take my children to and from school and activities. We live in Larkspur, our children go to school in Monument and we have sports in Castle Rock, so we drive quite a bit. I’m not sure that I’m comfortable with a small fix and using a different type of oil to see if my engine will be salvageable. My questions: Can you confidently let me leave your dealership and guarantee that my family will be safe and know that my engine will not fail due to the recall issues? If my car engine needs to be rebuilt or replaced do you have a comparable loner car until then? If my car engine needs to be rebuilt or replaced can you confidently say this is not going to affect my resale or trade in value? Do you have a recall trade in credit for a 2025 vehicle? I spent $85k on what I thought was a reliable vehicle for me to drive my 2 children around in. My biggest concern is that my engine stops running while I’m on the highway at a fast speed with or without my family. If my husband wasn’t in my car when the oil notification came on, we probably would have lost our engine. How is GM going to make this right and guarantee safety for my family? How is GM going to help with our frustration, anxiety and loss of time dealing with this mistake of selling vehicles with a defective engine? When will I have these answers?
