ENGINE, ELECTRICAL SYSTEM, POWER TRAIN
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.

ENGINE
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.

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.

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.

UNKNOWN OR OTHER
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.

ENGINE
On December 30, 2025, I was driving the Tahoe at a highway speed in Oklahoma City, Oklahoma. I experienced two engine shut-offs. I was able to get the Tahoe to the Chevrolet dealer in Midwest City, OK. Advisor Tim took care of the vehicle and said that they "couldn't replicate the problem." He did mention he had to add engine oil because it was a quart low. We noted that we are currently conducting an oil consumption test with a Chevrolet dealer in Elk Grove, Illinois. He said we had a strong case for it, but the Tahoe was safe for traveling back home to Illinois. The following days, the Tahoe performed well without any issues. On January 3, 2026, we left Spencer, OK, and headed back home to Illinois. Without any warning, while driving at highway speed, the engine shut off completely and would not restart. The failure occurred at approximately 9:00 pm on a pitch-black expressway about 40 miles from Rolla, Missouri. I was traveling with my wife and two children. We were stranded on the highway shoulder. A state trooper was dispatched for safety. The Tahoe required a tow over an hour later, and we had to take a Lyft to a hotel. Logistics at that time in that location were complicated. Our family was terrified for our safety. Today is Sunday, and the nearest dealer is closed. We will have it dropped off tomorrow, January 5th, and go from there. We do not know how we are going to get back to Illinois. We have work and my son has school. The vehicle is currently disabled and under manufacturer warranty. This was a serious safety incident involving loss of engine power at high speed.

FUEL/PROPULSION SYSTEM, POWER TRAIN, UNKNOWN OR OTHER
This vehicle has experienced multiple substantial defects, several of which directly endangered my family, including an infant, and rendered the vehicle unsafe and inoperable for extended periods despite warranty repairs. Summary of defects and failures: 1.Electronic door locking failure The vehicle experienced an electronic malfunction that caused the doors to randomly lock, resulting in my infant being locked inside the vehicle when we exited. This wiring defect was later repaired under warranty but represents a serious safety failure. 2.Fuel pump recall and highway breakdown While driving my family of six on a major highway over an hour from home, the recalled fuel pump failed while in motion, leaving us stranded on the side of the highway. We were forced to arrange an Uber for transportation. This incident placed my family in a dangerous situation and constitutes a major safety-related defect. 3.Transmission failure and extended inoperability The vehicle suffered a transmission failure that rendered it unsafe and inoperable. The dealership required over one week to schedule service and more than two additional weeks before the vehicle was inspected and repaired. The vehicle was out of safe driving condition for approximately one month. Upon return, the vehicle experienced additional failures, including a dead battery. 4.Known poor design defect – rear entertainment screens The rear entertainment system screens cracked due to a widely known poor design and placement issue, unrelated to misuse. 5.Rear headrest internal mechanism failure The internal mechanism of a rear headrest failed and requires replacement, further demonstrating ongoing quality and safety concerns. Due to the number, severity, and safety-related nature of these defects—combined with cumulative downtime exceeding 30 days—I have lost all confidence in this vehicle. I no longer consider it safe or reliable for transporting my family.

AIR BAGS, ELECTRICAL SYSTEM, POWER TRAIN
Vehicle continues to experience flashing air bag light and service self-restraint system warning. Brought in twice in 2025 for self-restraint system but dealer refuses to cover under warranty. On December 18, 2025, experienced complete power and electrical failure while in transit on a turning lane. The vehicle was unable to start, or open any windows, and the transmission would not shift back into park or neutral while obstructing traffic near an active railroad. Vehicle battery was replaced and was able to safely put vehicle into gear. Vehicle battery replacement allowed for normal driving; however, from that date on the transmission started shifting harder and jerkier. On December 31, 2025, vehicle was being driven on the freeway to then experience difficult shifting and reduced power. Subsequently, the drive indicator began flashing red and a service transmission indication appeared. There has been at least three instances, since vehicle purchased, where sudden loss of power and control of the vehicle in motion has occured.

POWER TRAIN, ENGINE
I asked the dealer for information about the L87 6.2L engine rod bearing failure recall. I was told that they wouldnt perform the work until i recieved a letter from GM. This was when i got my first oil change. Then every oil change after that i asked the same question. At 43401 miles i parked the vehicle and havent driven it since. I am afraid to have something happen to me or my family. I paid $82,000.00 for a vehicle that GM's fix is to add thicker oil. I think that the rods and bearings should at least be visually inspected. The dealers maintenance manager at Kunes Lake Geneva says theyll listen to it with a stethescope. If it sounds ok theyll change the oil. I paid way to much to chance my familys safety on thicker oil. To make the situation better the vehicle blue books for $56,000.00 IT DEPRECIATED $26000.00 IN TWO YEARS. That is unacceptable.
