ENGINE
I purchased a 2023 Chevrolet Tahoe on December 17, 2025. On January 17, 2026, with approximately 17,000 miles, the vehicle experienced a catastrophic engine failure while I was driving. The engine seized without warning, causing a complete loss of power and leaving me stranded on the side of the road. At the time of the incident, my newborn child was in the vehicle, creating a serious safety risk. The vehicle had no prior warning lights or indicators before the failure. After the incident, I learned that there was a known recall or service update related to engine oil viscosity for this model year. This information was never disclosed to me at the time of purchase, and no recall documentation or corrective service was provided prior to delivery. I have since been informed that engine replacement will take over 30 days due to parts availability and that no loaner or rental vehicle is available during repairs. Given the catastrophic failure shortly after purchase, the undisclosed recall, extended repair time, and safety implications, I no longer feel the vehicle is safe or reliable.

ENGINE AND ENGINE COOLING
The contact owns a 2023 Chevrolet Tahoe. The contact stated that while her husband was driving at 70 MPH, the vehicle experienced a loss of automotive power. The check engine and "Oil Pressure Low" warning lights illuminated, and the vehicle unintendedly decelerated. The contact stated that while driving at various speeds, the message "Press START Button" was displayed, and restarting the vehicle temporarily fixed the issue. The contact stated that after further inspection, the contact became aware that the vehicle had independently shifted from neutral(N) to park(P). The vehicle was towed to a local dealer, where it was diagnosed; however, no cause for the failure was determined. The local dealer advised the contact that the oil level was possibly low, and an oil consumption test was needed. The vehicle was not repaired. Upon further investigation, the contact related the failure to NHTSA Campaign: 25V274000 (Engine and Engine Cooling); however, the VIN was no longer included in the recall. The manufacturer was made aware of the failure. The failure mileage was approximately 33,253.

I sent this to GM Corporate on 2/12/2025: I'm writing regarding the recall on certain 2020 Chevy Tahoe transmissions. My husband is meticulous with his vehicles including all regular service updates and recommended appointments. It literally looks like it came off the showroom floor 5 years after buying it. Unfortunately, when returning on a trip our vehicle suddenly increased rpm's and wouldn't respond while going 65 miles per hour. Thankfully, it reengaged, and we were okay but imagine what could have happened! We managed to get it home, but while attempting to back up it wouldn't shift. We had to have it towed and have been told our transmission is SHOT! It will cost us over $7000 to replace?!! We attempted to call the GM customer service number to Complain and see if they could provide some help. They put us in touch with a service manager in our area whose voicemail was full and took a week to connect with. She basically said there is nothing she can do as it is within the 5 years but over on miles. So, here we sit with a vehicle we have babied for 4.9 years that needs a new transmission. I am asking for you to listen. Asking for you to expand the investigation/recall to include ALL 2020 (or related) vehicles. Something isn't adding up, and you are leaving customers who have paid off their $60,000 vehicle stuck with more $$ to pay because of an about defect. This could have killed us. It literally froze while we were driving, and now we are without a vehicle waiting for a new transmission. We have never had issues with the transmission before. How does a transmission just go? Definite defect!

Truck bucked twice in high-speed lane of the highway, gas pedal went soft and we luckily were able to coast the truck to the side of the highway without getting hit. The truck put itself in neutral when we lost the engine and the truck would not restart. It had to be towed, while me and my two kids stood on the side of a dangerous highway for 45 minutes in the snow. The truck has 52,000 miles, Engine was already replaced at 10,000 miles. It just passed the recall inspection and had the upgraded oil that was recommended.

FUEL/PROPULSION SYSTEM
My Tahoe 2021 RST has been leaking what smells like diesel. This goes all the way back only months after I bought it new. This came and went sometimes once a week sometimes once a month. And for the next few years many months I could smell it but no leaks but in the last 10 days the diesel leak has been massive. It leaks from under the engine and if the hood is opened the diesel leak is all over the engine. The smell has been noxious sunce the beginning. Over the years the smell was there off and on. Comes and goes. But the last few months it has been everyday. Apparently the shop had fixed and replaced some parts several weeks ago but the smell of diesel never went away. Now it is in the dealer shop again. Because the fuel leak is too massive and the smell is ever worst.

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.

POWER TRAIN, ENGINE
* Sudden Catastrophic Engine Failure. * The car lost power in the middle of a high traffic, very dark country road, forcing her to stay in the middle of the (undivided) road in the dark hoping cars didn't slam into her. A Collin County Sheriff was dispatched to keep her safe until the tow truck arrived almost two hours later." * The vehicle was towed to a dealer where they confirmed that the torque converter, valves, lifters had failed. Dealer didn't disclose that there was any issues for these engines, which there is. It's a 6.2L V8 Tahoe High Country. * It has only been inspected by the dealer, not the manufacturer, police, insurance representatives, etc... * The vehicle indicated a traction control problem, then the engine light came on, and then the engine failed followed by loss of power. All happened in rapid succession WITH NO OPPORTUNITY FOR THE DRIVER TO GET TO A SAFE LOCATION. * There was no warning or other symptoms preceding this. The vehicle has always been faithfully serviced at Chevy dealerships consistent with the manufacturers recommendations.

Roof racks have deteriorated due to sun exposure and have cracked where the contact the top and started leaking. The paint on the roof and hood had also failed. I had to have the top and hood repainted prior to having it ceramic coated. The roof racks leaking have damaged the headliner in the cargo area. I have tried to reseal them with a silicone sealant since removing them or replacing them is too expensive and would require removing the entire headliner to access the connecting bolts.

VISIBILITY/WIPER
For the third time, my windshield wipers quit working in the middle of a rain/snow storm. Have taken the vehicle into GM service under warranty twice, the first time they updated the software but that repair only lasted a few months. Second time they replaced the windshield sensor, that lasted a few months. Now today, driving home in the snow my wipers quit working altogether. The sprayer worked, the rear wiper on the same handle works, but nothing else I could do gets the wipers to work. This is a big safety concern as it has happened all while driving in I climate weather.

ENGINE, FORWARD COLLISION AVOIDANCE: WARNINGS, SERVICE BRAKES
While driving on I-90 in Montana on a clear, sunny day at the posted speed limit of 80 miles per hour for one hour, the vehicle began making knocking noises then, all of a sudden lost power. Upon inspection at the nearest GM dealership service department in Butte, MT, I was told something within the engine broke. I have attached an emailed repair bid from the GM service department and have copied and pasted the highlights here: -Engine, Lines, Radiator, Water Pump, and Tune up ($14,400.00) -Cam, Lifters, Lines, Radiator, Water Pump, and Tune Up ($11,400.00) -Master Cylinder/EBCM ($3,310.00) Previous to the incident, all recommended and routine maintenance was performed at intervals recommended by GM and by GM dealership service departments and/or the Valvoline Oil Change location in Missoula, Montana. The odometer reading was between 95,000 and 96,000 miles at the time of incident.

FUEL/PROPULSION SYSTEM
I noticed the vehicle had intermittent hesitation while accelerating to merge onto a freeway on the previous evening. We drove straight home from there and the next morning as we prepared to go somewhere the vehicle lost power in our driveway and now will not start. Trouble code P129F Fault code is being thrown. This seems to be related to the GM issued TSB PIP5964 and the also GM Recall N252516900 . However, GM is denying that our VIN should be affected. I'm concerned that they're not aware of or intentionally excluding vehicles that could have this issue. Had we lost power while in motion, like on a busy freeway or crossing an intersection, this could have been catastrophic.

ELECTRICAL SYSTEM
On multiple occasions, my car has locked my keys on the INSIDE of the vehicle. I have put things inside my vehicle before leaving and closed all the doors, upon returning, even just a few minutes later, my doors are locked and I am locked out of my vehicle. Additionally, my car is not detecting my remote. I cannot unlock my car with the buttons on the door and need to have my keys in hand for my car to detect the fob. Additionally, if someone opens the door while the car is running but in park, and then closes the door, the Car will beep as if there is no longer a remote detected. This has happened on multiple occasions. I have changed the batteries in the fobs multiple times, switched out my fobs so I was using a different fob and it has happened with both of my fobs.

EXTERIOR LIGHTING
I recently purchased this vehicle from a dealer in FL, but unknown to me at the time was the headlight adjuster on driver side was broken, causing the aim to drop to the bottom limit. This causes only the passenger side light to illuminate the road. I discovered this problem about a week after purchase. The dealer does not seem to be willing to correct this issue. This is a common problem for these vehicles, verified with online search's. The fix is to replace the entire headlight housing which is quite expensive, and then the labor to remove and replace the front bumper assembly.

On two occasions my car shut down after hard braking while approaching stopped traffic on a freeway. The Chevy dealer has not been able to locate a cause. In both cases I was in the travel lanes when the vehicle shut down and fortunately I was not struck from the rear. It took me time to recognize that the car was dead, place it into Park, then recrank it.
