While driving on the highway at high speed, my vehicle suddenly shut down and went into neutral. After a few minutes of trying to start it, it started and I was able to drive it home. The following day, on my way to the dealership for an inspection, while driving on a busy street, it shut down again. This time, it wouldn't restart, and I had to call the police and a tow truck to have it towed to the dealership. I was freaking out as I had my daughter inside the car with me. At that point, the vehicle had around 26,000 miles. The dealership inspected it and determined the engine was faulty and needed to be replaced. After the engine was replaced, the vehicle seemed fine, but recently, I've been experiencing problems again. The car struggles to start when it shuts off during stops, using the auto shut-off feature, and there's an intermittent hard shifting issue. It feels like the engine is failing again or maybe the transmission, but I've been told that unless the dealership can replicate the issue when I bring it in, they can't do anything. I'm concerned about being stranded on the road again, especially since my daughter is always with me. The vehicle’s engine and mechanical components don’t seem reliable, and I no longer feel safe driving it. However, I have no other option as it is my daily car for work and everything else. I’ve asked for an extended warranty from the dealership after the engine replacement, but I was told GMC doesn’t offer one for this issue. I’ve seen others on social media report similar problems, and I want to share my experience, as I’m just one of many customers facing this issue.

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!!

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.

Engine
On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).
