2023 Cadillac Escalade

The vehicle has approx. 28,000 miles on the odometer. Always serviced at Cadillac on a regular maintenance interval called for by the vehicle and manufacturer. At highway speeds, the vehicle lost all power and came to a stop in moving lanes of traffic putting my family at risk of being rear-ended on a highway at highway speeds (greater than 65 mph). The vehicle was later towed by OnStar / roadside assistance. The Cadillac dealership that received the Escalade determined this was a failed motor. The Service Advisor at the Cadillac dealership mentioned this was a common issue on L87 blocks / engines. They've already seen a few at their dealership and GM had confirmed to them this is a known issue (motor failure on the 6.2 liter V8 L87s). There were no warning lights or other symptoms leading up to the motor failure.

Complete engine shutdown without warning. Vehicle at Cadillac of Las Vegas in Nevada for inspection purposes. Vehicle came to stop in 45 to 50 mph traffic with strong possibility of rear end collision. Vehicle was being driven in inner lane of four lane highway with no way to get to far right lane. No shoulders on [XXX] and close to [XXX] to get off of highway. Rush hour traffic with rear end collision possibility. Onstar called Las Vegas Metro police department for assistance. Policemen parked there squad vehicle behind ours with their lights flashing to prevent a rear end collision. Vehicle has been diagnosed by dealer with a seized engine. New engine ordered on January 13 2025. Engine on back order with no expected delivery date. No warning lights or messages that engine was malfunctioning in any manner prior to shut down.

While my wife was driving on the Pennsylvania Turnpike, her vehicle suddenly shut off without warning. Since there was no shoulder, she had to coast to find a safe place to pull over. All the dashboard lights came on, indicating what appeared to be an electrical issue. She attempted to restart the vehicle several times, but only received a message stating, “Battery low, needs charge.” She contacted OnStar, expecting prompt assistance, but the experience was far from what’s advertised. She waited a total of 45 minutes just to speak with someone, only to be transferred to another representative. Despite having paid for OnStar services when we purchased the vehicle, they refused to cover the towing charges because she was on a private highway, forcing her to pay out of pocket for a service we had already purchased. During this time, it was extremely cold and windy. My 5-year-old daughter and wife waited about an hour and a half for the tow truck to arrive, and then an additional two hours while the driver secured the vehicle onto the flatbed. Since the car was completely dead, they had no heat the entire time. When they stepped out of the car so the tow truck driver could load it, they discovered they couldn’t get back inside—the doors wouldn’t open due to the lack of power. This entire ordeal was not only frustrating but incredibly unsafe for them. Having the vehicle shut down without warning on a busy highway, especially with our young child in the car, was terrifying for them. After our vehicle was at the dealership for a week, we were informed that the engine needs to be replaced. We were shocked to learn that this is a common issue with GM’s 6.2 engines. To make matters worse, there is no estimated timeframe for the repair because the engine is on backorder. For reference, the truck only has 24,000 miles on it and has been exclusively serviced by authorized Cadillac dealers. This experience has been both disappointing and deeply concerning.

pulled up to a gate and was waiting for it to open, no warning at all, the engine died while in drive. I restarted it, pulled up to a stop sign, waited my turn, the engine died again. I was on my way to get my daughter from school, but didn't feel like my Escalade would have made it. so I drove it to the shop to check the battery. It wasn't the battery so we took it to the dealership. So thankful it didn't happen while I was driving in traffic, without any warning, it could have ended badly. took it to the delearship, same thing happened to the mechanic when he was test driving it. He said it is a problem with the engine, and we will have to wait for at least a month for a complete engine replacement. No warnings at all before this happened. This incident happened on 1/29/25. The escalade has approximately 16k miles on it.

I own a 2023 Cadillac Escalade. I was traveling on Interstate 75 to Tampa from Naples on Wednesday evening (01/29/25) when, at approximately 9:30 p.m., the check engine warning light illuminated. My vehicle suddenly lost power in the middle of the interstate and decelerated quickly. Thankfully, I was able to safely maneuver my vehicle from the fast lane to the shoulder of the interstate. I tried to re-start my vehicle as speeding traffic zoomed passed me. I was stuck on the interstate and afraid to get out of my vehicle for fear of being struck in the darkness. There were no warnings. My vehicle just shut off. I had my vehicle towed to a local Cadillac dealership. The mechanic who diagnosed my vehicle determined the engine failed and needed to be replaced. The local dealership stated the replacement engine is on backorder, and it may take weeks before my vehicle can be repaired. I now have a rental vehicle while I await for my vehicle to be repaired. Upon researching this issue online, I found NHTSA Investigation PE25001, where the manufacturer is investigating this engine failure issue. My vehicle mileage is approximately 28,000.

While driving on the interstate at 80 mph, my vehicle switched to neutral and began to decelerate. I could not shift back to drive. Thankfully I was able to maneuver through the busy interstate to pull over to the median. We almost triggered an accident due to the deceleration while in the fast lane. Once we were able to stop in the median, I had to turn off the vehicle because it would not change gears. The engine would not start and we were stuck in Park mode. The vehicle had to be towed from the median of the interstate.

The contact owns a 2023 Cadillac Escalade. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power. The check engine warning light was occasionally illuminated. The contact stated that after attempting to restart the vehicle, the vehicle failed to start. The vehicle was towed to the local dealer where it was diagnosed and determined that the engine needed to be replaced. The local dealer informed the contact that the parts for the repair were on backorder. The vehicle was not repaired. In addition, the contact stated the vehicle was towed to the dealer on several other occasions. Upon further investigation, the contact related the failure to NHTSA Investigation: PE25001. The manufacturer was made aware of the failure. The failure mileage was approximately 30,000.

I was driving home from getting groceries when all of a sudden the vehicle starts to make a loud noise from the engine (no warning lamps/lights or any messages popped up.) I proceeded to go home and call my husband and ask for his help with the problem. I recorded a video of the car and sent it to him, and he said that it sounded like the engine is knocking and told me to shut the car off and call the dealership to further discuss the situation with them. After calling the dealership they towed my car to get it diagnosed. It has been a month or so now since leaving my car with them and they still cannot diagnose the issue.

I was driving my 2024 Escalade on the interstate at 80 mph when the vehicle started jolting and acting as if it was going to stop. My speed dropped from 80 to 55 while the screen started flashing "press start button", all while the vehicle was still running. Luckily I was able to cross 4 lanes of traffic and pull over on the shoulder. I was fortunate that I was not hit. I turned off the vehicle and then started it back up. Two days later, the vehicle was once again acting as if it didn't want to start/go. After a 40 minute trip, the vehicle died as I pulled into my driveway. It did start back up but the engine was making horrible sounds. I had to be towed to the dealership. I had no warning lamps prior to the flashing "press start button". The problem has been confirmed by the dealership. Engine failure. I need a completely new engine. This will soon be 8 weeks ago that my vehicle was towed. I have been in a rental since that day. The dealership says they have no updates as to when the engine will arrive. After tests done at the dealership, they did confirm that the problems were happening on longer trips. Most of my driving is around town, hence why I noticed the problems when I had been driving for 30 plus minutes.

My Escalade stopped running while on the highway at 70 MPH. There was no warning lights on at the time. The engine shut down and the truck stopped in a live lane. My entire family of 6 were stopped in the left live lane with traffic passing us on either side at excessive speed - it was very dangerous. Truck was towed to dealer - where it was diagnosed as a bearing issue requiring a full engine replacement. That was over 2 months ago - GM cannot even tell me when a replacement engine will be available. Please note I am in Toronto Canada and was made aware of your investigation online.
