2024 Chevrolet Tahoe

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. When we contacted Titus-Will Chevr

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.

Entertainment System/Radio -- not working. No audio. No audio noise even when the blinker is engaged. After several visits to the internet/YouTube I understand this has been a common problem with GM models. Some are able to restart under 'safety mode'. My case ... radio comes on when it wants to and then cuts off. My vehicle is 15 months old .. 38,000 miles.
