While driving from Boise, Idaho to Jackson, Wyoming our 2022 Tahoe 6.2L with 70K miles shut down at 85MPH on Highway 84 outside of Pocatello. Luckily, my wife was able to coast off the exit. We had the Tahoe towed to the Dealer and advised it would be 4 months for a new engine as our order was number 4,000 in line for an engine. Luckily, all of a sudden engines arrived from the supplier and was replaced in 3-4 weeks. Tariffs must have sped up the process. Downside, I paid 50% as we were out of warranty and GM would not cover the entire cost. Now I see the recall and would expect to be re-imbursed. We will see.

At 22,000 miles on the Interstate highway, vehicle suddenly lost all power, no throttle, went into neutral and we were lucky to be able pull it off to the shoulder without an accident. It had stalled and after multiple tries we were able to restart it. Then the check engine light came on and we drove it directly to dealer. There was a code for camshaft sensor and we were told all lifters needed to be replaced. Upon doing so, they found metal pieces in the engine and said entire engine needed to be replaced. The engine was on back order for up to several months. We waited a month then decided to trade due to loss of vehicle use. Dealer was very helpful during repair but no assistance from GM for a known issue on the 6.2L that could have had a negative outcome on the highway. This was not only a safety issue but a very expensive situation to trade out of for an almost new car.

3 Separate Major Problems: 03/23 - 8500 miles. Driving at 70mph on highway, received message on drivers display "Conditions Not Correct For Shift", car went into Neutral, no acceleration possible. Was able to safely get off highway. Stopped car, and restarted, error went away and car was able to be driven further without incident. Chose to not take in for service, 4/23 - 9000 miles. Noticed fluttering noise coming from engine bay when lifting off gas after acceleration. Service eventually found lifter/bearing issue. Whole engine was replaced under warranty. Was without car for 3 months. Further research online found that others experienced the same issue while driving and had engine failure at speed resulting in life threatening driving conditions. 4/25 - 31000 miles. Last weekend, driving at highway speeds and came to traffic standstill in left lane on major highway. Went to accelerate, and received "Conditions Not Correct for Shift" message, car went into Neutral and would not accelerate. Turned car off, and tried to restart and car was stuck in Park. No way to access Neutral, leading to blocking of left lane where cars were approaching and avoiding us at highway speeds. OnStar was notified immediately with the severity of danger stressed (2 adults, 2 children and dog remained buckled in the vehicle). However, CHP took over 1 hour to arrive, shut down highway and somehow was able to start the car one time and get into Neutral for CHP to push car safely to shoulder. Dealership alerted me to failed "Fuel Control Module" To have to 3 major engine related incidents that could have lead to accident or death is unacceptable. Online research shows these issues have been common for this vehicle engine and is absolutely unacceptable. For a driver to not be able to safely engage a Neutral override is absolutely unacceptable. I was informed by the tow truck driver that a special tool was needed and you had to crawl under the vehicle to engage neutral override.

It’s my understanding that the NHTSA is investigating problems with the 6.2 L engines on 2022 Tahoes that have sudden lost of power please add my name to the investigation- GM has refused to help I’m hoping that a recall which is warranted will help with the $11,869 cost to replace the engine.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.
