Engine: Power lost and engine shut down. Yes, it is available for inspection. Warning Lamps: Engine lamp came on: [XXX] [XXX] Engine shut down while driving. While bring my Grandson, home from school. I was on the ramp to exit the interstate, at the stop sign I lightly touched my brakes because I was going very slow, nothing was coming when I accelerated the engine totally shut down in between both lanes on a state highway. All of the warning lamps on the dashboard were lighting up and blinking, all of the alerts were making noises, no power and I had no control of the vehicle, then the “press start signal” came on, I had to quickly place from drive to park, and then press the start button to crank the vehicle. While this was going on my Grandson asked me in a startled voice “what’s happening”. Scary is not the word “I saw my life and his life flash before my eyes” with my Grandson in the vehicle. That’s a [XXX] of a feeling that you never want to experience. Then he said “this is nothing but a tin can ”. All of my family calls this vehicle a “Tin Can”! This was a very dangerous situation that could have been life-threatening or death. The problem has not been reproduced. Dealership sent a GM Field Service Engineer to inspect vehicle on 3/18/25. I have had many problems with this vehicle that cannot be diagnosed. Engineer test drove twice and scanned for codes before and after test drives. His findings: no codes found, was unable to reproduce power loss, and loose negative terminal on battery post tightened.

At approximately 19.000 miles when the car sits for an extended period of time, at the first start up, blue smoke comes from the exhaust tail pipe. Brought it to the dealer and they said that, that was normal. With the issues they are having with the engines, I wanted this to be noted, because blue smoke is indicative of either bad piston rings or bad valve seals. This should not be happening on a vehicle with 19,000 miles and have oil changes at every 3000 miles.

We were driving on a busy interstate in Knoxville, TN on a Sunday. We were 2 hours from home and my 2023 Tahoe basically went into limp mode while I was in the fast lane and the check engine light came on. No warning in advance. The speed reduced, which backed traffic up, and put me and my 4 children in danger. We finally got off the interstate and the vehicle had to be towed in to the nearest dealership. I had a friend drive us to enterprise where they put us in a Jeep Grand Wagoneer. On Monday, I received a call from the dealership stating they had good and bad news. The good news was the repair is covered by warranty but the bad news was it will be 2-3 months before they can get the part. The part is on back order and several people are waiting ahead of me. The said part is a valve body for the engine/transmission. The dealership also informed me that warranty will not cover a non-GM vehicle and that they will only pay for a rental up to 44.00/day. It’s not my fault the part is on back order, nor that enterprise gave me a non-GM vehicle. Also, I have a family of 6, which is why I have a Tahoe and I cannot be put in a small sedan. My children play sports, we have upcoming vacation, and quite frankly, I didn't pay 90,000.00 for a vehicle to be placed in a vehicle that I don’t feel is safe for my family. If I had wanted a sedan, I would have bought one. GM should take better care of their customers, especially when something is like this is not the customers fault!!! I have contacted GM and have been told I will be called back by a supervisor each time I talk to someone. This is unacceptable!!

This issue seemed to stop until one Saturday when i started the vehicle i noticed a small tick. This ticking sound continued to grow. The vehicle then shut off again with warning while driving. 7 days had gone by since the first episode. When I started the vehicle again there was a very pronounce rapping and it sounded like parts inside the motor were coming apart. When I arrived home i called Onstar. They did a diagnostic twice and said the motor was not showing any codes and running perfect. I had it towed from my house and upon inspection the motor is blown with 10,000 miles

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete 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.
