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.

Vehicle suddenly lost power at 70mph in heavy traffic. This was after a very brief flash of the electrical system off and then back on. Vehicle was safely pulled to the side of the road (luckily). The electrical system kept demanding to “push start” and then would shut off and then immediately come back on, but without the engine starting. The vehicle would not completely turn off, or turn back on from that point forward, killing the battery in the process. We called Onstar, who had it towed to Bill Estes Chevrolet in Carmel Indiana. Mark in the service department then informed us that the engine was completely seized up and would require an engine replacement.

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.
