My wife and I purchased a certified used Cadillac Escalade Sport Platinum with 36K miles on it from a reputable dealership near our home. After having the vehicle for less than a week, the engine just lost power suddenly and without notice while our entire family (3 kids) were on our way home. We were able to coast off the main highway and onto a crossing road before it glided to a stop in the middle of an intersection. We were able to get the vehicle towed back to the dealership where they are telling us it needs a replacement engine. I am very concerned with how the event unfolded, and it could have been much worse had it happened where we were not able to get off the road. I am happy GM and the dealership are working quickly to replace the engine, but now I have safety concerns and feel like the vehicle has lost some of its value. Even before I could re-title the vehicle or make our first payment on it. I am reading similar stories and am baffled how GM could produce an engine with such a widespread problem, especially when paying significant money for the vehicle.

My wife was driving this vehicle home after dropping off kids at school when the engine suddenly stalled in the middle of the road. Luckily no one was directly behind her or she would have been in a collision. After being towed to the dealership, they informed us the engine "failed". There was no check engine light or warning message prior to the engine suffering sudden and catastrophic failure. Vehicle has less than 28k miles. The car is currently at the dealer with no time frame for repair because the engine is on "back-order".

After spending 3 months in Palm Desert CA, we were heading home to Colorado on Saturday [XXX]. Just a few miles east of Barstow CA, traveling about 70 mph on [XXX], our Escalade just died and shifted itself into neutral. Luckily we were able to guide the car on to the shoulder area. The experience was terrifying as we sat there for 4 hours……… speaking several times with both OnStar and Cadillac Roadside Assistance. A tow truck driver FINALLY arrived about 1:00 PM and took us and our Escalade to Victorville Cadillac where we arrived around 2:00 PM. Because it was Saturday afternoon, they would not be able to look at the car until Monday. We met with the General Manager, who provided us with a loaner car. The car was fully packed with our belongings and we were assured that the car would be secured on their lot. On Monday [XXX] at 11:05 AM, Jon Adams from the service department called Fred to say that the engine was blown and there were fragments in the oil pan. We headed to the dealership where we were for the next 4 hours. We were told that it could take several weeks for them to get a new engine delivered. We were over 900 miles from home and really had no other option than to buy another car from them. Of course, we had NO intention of trading in the Escalade as it we only had it for 1 year and 8 months AND only with 10,245 miles!! We were two mentally exhausted [XXX] who just wanted to get home!! The GM assured us that he would give us the full trade-in value of the Cadillac as if there we no engine issues. So, we purchased a 2024 Chevy Tahoe High Country in the amount of 91K. They gave us a trade price price of $81,550 for the Cadillac (we paid $110,775 on [XXX]) After spending 3 nights in Victorville, we headed home on 4/16/24. On 4/22/24 we requested a copy of the work order to submit to Cadillac only to find out that our Cadillac had already been repaired on 4/19 and on their lot for sale on 4/22 for $109,651!

I called dealer and told them that the suv was making a ticking sound and played them a recording of it. They told me that i could drive it in or call an 800 number and maybe get it towed. I decided to drive it in as towing it would prob take it to a dealer i did not know. There were no lights on indicating an issue. I was stopped waiting to turn left across traffic when the engine started making all kinds of clanging noise. At this point it quit and after a few attempts i got it restarted and towed it in to dealer the engine failure with out warning left me and my family in jeopardy in the roadway. Now i learn that lots of these 6.2 v8s are blowing up as my dealer alone has several of them out back waiting with no eta on repair parts coming. So not only were we put in pearl but i have 125k in a brick setting at the dealer. And givin a smaller auto that i can not pull trailers with. I feel endangered and ripped off pleasse help.

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. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.
