I had a 2023 Escalade that was purchased new and it had TWO motors seize up in it. I filed a separate complaint for the 1st one. This will have to do with the 2nd time. The 2nd motor that seized up happened also on vacation, with a trailer. These new 6.2’s don’t like a trailer or any type of load. We were NOT even at 1/2 of the max trailer amount. We have had the 6.2 engine for 12 plus years in different vehicles pulling the same trailer and never had an issue until this 23’. So we were traveling in the panhandle of OK, in July, not close to a town, doing 68 mph and a warning light came on for 5 seconds saying something about engine oil hot, we couldn’t even read it before it went away and the engine died. Doing 68mph down a highway pulling a trailer. We got it safely to the side of the road. I had to leave my husband and son on the side of the highway in the middle of nowhere, in the hot as hell Oklahoma panhandle to drive back to our hometown with the family that was traveling with us to get our truck. My husband and son had to wait for 4 hours on the side of the highway. It was super dangerous. Not close to a city, in July when it was super hot. There was not enough room in the car I road in for my son and my husband had to stay with all our stuff so it didn’t get stolen! It took me 4 hours to get back to them and the tow truck showed up at the same time as me…4 hours later. It was awful. And this was the 2nd time!!!! This 23’ Escalade now has it’s 3rd motor in it before 30K miles!

My 2023 Escalade Sport that was purchased new has had two engines seize up while driving. The first time happened was July 17th, 2023, when we were traveling for vacation. It had 10,697 miles on it. We were driving 70 down the highway with the cruise set and it just died. No warning at all. There was no shoulder, the side of the road was steep and muddy so my husband had to time it to get it in someone’s driveway safely. We were pulling a 14ft trailer. We were NOT close to the max weight, so that had nothing to do with it. How it happened was not safe at all. It was scary having that happen with no warning and we were not close to a city. We had to call family to come offload our car as we had suitcases for vacation. We also had to have another family member bring a truck to pull the trailer home. We lost days of vacation over this. The car was towed to our cadillac dealer and we were told it needed a new engine. Making another claim for the 2nd engine that failed in this same car.

On Saturday, December 28, 2024 @ 1 PM while driving 70 mph on the I-10 freeway; the vehicle downshifted causing the engine RPM’s to increase. We had 15 seconds to make a decision as the vehicle shutdown immediately. On my driver’s side were 5-6 lanes of freeway with cars going 70 mph, while on the right-passenger side was Exit 73b called Waterman Ave. in San Bernardino, CA. We managed to park on a small strip dividing the 5-6 lanes and exit lane, as we couldn’t get over to the shoulder. In addition, the vehicle was stuck in Park and would not go into Neutral. The engine wouldn’t start. NO WARNING LIGHTS. Called 911 at 1:04 PM and asked for an officer to assist us because we were scared for our lives sitting on the freeway. We were worried someone would hit us from behind. About 1/2 hour after my 911 call an officer arrived. We told him what happened, and informed him we called AAA’s Roadside Assistance. The officer informed us that if there was a call, he would have to leave, and he was worried we’d get hit by drunk driver going 70 mph. Our vehicle was towed to Dutton Motor Company in Riverside, CA. • Engine failure possibly due to oversized lifter bores. Replace the engine to fix. • We had 15 seconds to stop suddenly going 70 mph, not on the shoulder of the I-10 freeway. Our safety was at risk so I called 911 asking for an officer. • Dealer told us the engine needs to be replaced. • Vehicle not inspected by police, insurance, just shop at dealership. • No warning lights. Absolutely nothing.

Engine failure at 29k. There were no signs of malfunction or warning. There were two incidents before Cadillac approved warranty for a new replacement engine. First incident I was passing a vehicle on a two lane road when I was mid past the car suddenly vehicle died electrical and all. Message came on saying to restart engine. Thankfully I coasted past the vehicle I was passing and onto the shoulder of the road. Vehicle would not restart and left us stranded for hours waiting on a tow company. Had it towed to Cadillac where they told me it was a faulty fuse that caused the failure and it was fixed and was a fluke. They got it running said no other issues were found and vehicle was good to go. I had it back for only a few days and my wife and I were on the way to a restaurant. I stopped at a red light, again no signs of malfunction, no warning lights etc. the vehicle just completely dies again. Would not restart and left us stranded in a busy intersection. Thankfully a state patrol was sitting at the light across from us and came to our assistance and called for a tow. This time at the dealership they said engine failed and needed replacement. Just got it back as of Jan 2025 after 3 months. We were extremely fortunate that both times my 1 year old was not in the vehicle with us and no accidents occurred. From my knowledge 3 other Escalades were at the dealership for the same reason as ours was. Extremely dangerous situations the vehicle put us in and disappointment from a 6 figure vehicle from a manufacturer known to be reliable. I’ve owned two prior generations of Escalades and multiple other GM vehicles never having any issues and put over or close to 100k miles on each of them. Note we bought this vehicle “used” around 10k on it when purchased so we were unable to file a lemon law claim against it. Thankfully it came with a 100k bumper to bumper warranty.

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.
