2021 Cadillac Escalade Engine Problems

On 7/14/26, I scheduled Escalade to be serviced at local dealership (MT) when A/C went out on drivers/middle vents and I noticed a faint ticking noise under hood. Was told engine lifters were damaged & needed to be replaced. Service was completed 7/21 and I picked it up that evening. On [XXX] my husband and I departed for San Diego; stayed overnight in St George UT. On [XXX] around [XXX] pm, I was driving in second from left lane on [XXX] San Bernadino area. I braked quickly as traffic from far left lane merged right to avoid debris from a refrigerator that had shattered all over the highway. The Escalade engine failed and shut off without warning or any indicators. I tried several times & could not restart the vehicle; therefore I could not shift the vehicle into Neutral so it could at least be pushed off the highway. My husband immediately called 9-1-1 and requested assistance. I frantically searched the internet for a way to shift to neutral when there is no power to the vehicle, and discovered the manual neutral override is under the vehicle. It was impossible for us to attempt that in this situation. All we could do was sit in the middle of the freeway with our hazard lights on and pray while we waited for law enforcement to arrive while heavy fast-moving traffic flew around us, honking and cursing at us to "get out of the way". This was a very perilous situation and our lives were endangered. We were helpless until CHP officers arrived on scene, followed by a tow company. The vehicle was towed to the closest dealer service center. We were told four days later that the entire engine needed to be replaced. It remains at the CA dealership while we fight with GM Warranty to have it shipped to MT. If the engine failure recall was dealt with appropriately as promised by GM, this would have been avoided altogether. **Note: Escalade passed engine recall inspection 10/9/25; was 'upgraded' to 40W oil. Regular service/oil changes completed 1/23/26 and 6/8/26. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INF

Following a recent oil change, I started the vehicle back up to drive approximately an hour to another city and the engine was making a horrible “knocking” sound. Took the vehicle back to the dealership and it was confirmed catastrophic engine failure which fell under GM’s known 6.2L engine issues. My safety and my children’s safety were put at risk because had I not drove directly to the dealership instead of getting on the highway as planned, the vehicle could have died at highway speeds posing a serious safety risk. No warning signs, no engine light, nothing prior to the failure.

On 4/17/2026 in Tomball Texas I experienced a sudden loss of engine propulsion while driving on a 4 lane road. The battery had voltage, hazard lights and radio worked normally. The car rolled to a stop in a traffic lane as this road has no shoulder and was put into park. The push button ignition was pressed but no restart of engine. The car was towed to the dealer that same day and told me the engine was "seized" and they have seen many of the same engines with the same problem. This car is not under the current recall for the L87 but those a few months to years from the recall lot have a current NHTSA investigation ongoing.

Incident

Mar 16, 2026

On 2/21/26, while driving approximately 60 mph, my car experienced a sudden loss of propulsion. The vehicle unexpectedly shifted into neutral and began decelerating, displaying a prompt instructing me to press the start button. I was able to coast to the shoulder and avoid a collision, but the incident occurred in active highway traffic on a Saturday afternoon and posed a significant safety risk. The vehicle had completed manufacturer recall service related to engine propulsion concerns less than 90 days prior to this event and had PASSED the associated safety checks. Approximately 5,000 miles had been driven since that service without prior warning signs. Given the nature of the failure and its occurrence after recall completion, I am concerned that the recall remedy may not adequately address the safety defect. A loss of propulsion at highway speed could reasonably result in serious injury or death. Cadillac has NOW agreed to replace my engine, but they didn't replace it when they had the chance in November. The recall parameters failed me.

GM issued a special coverage in bulletin N252508341 for the coolant control valve in my vehicle. This issue happened to my vehicle exactly as the symptoms are stated in the bulletin: check engine light, P1098 code, fan running at high speed with the engine on and off, and reduced acceleration. I took the vehicle to the dealer to be covered, and they say my vehicle is not covered by the bulletin. To be clear, the bulletin covers 2021-2023 Cadillac Escalades with the LM2 3.0L Duramax engine. My vehicle is a 2021 Cadillac Escalade with a LM2 3.0L Duramax engine. Which had all the issues and symptoms listed in the special coverage. Yet, they say it is not covered. This seems incredibly shady. And very wrong. Why in the world would they not be covering my vehicle? It seems unsafe to be driving a vehicle that has reduced acceleration, a fan constantly running at high speed, and a check engine light for malfunctioning parts. Faulty parts from GM which they have already acknowledged are bad.

See attached document for complaint. IN RE: GM Recall N252494000 I received notice in May of 2025 that my 2021 Cadillac Escalade is involved in a recall. At first my dealer said the part to repair is not available? Then in September we stopped by my dealer and he said the recall does NOT involve my Cadillac. So I will attach a copy of my notice so there is no question they notified me I have a defective Cadillac. Please someone tell me Why this happened? I want a different automobile!!! By the way I find it very interesting that Regina A. Carto,, Vice President of Global Product Safety and Systems FAILS TO PROVIDE HER ADDRESS?

A major recall has been issued due to possible engine failure. It sounds like a ticking time bomb and the dealer and GM currently refuse to do anything about it because “remedy not available yet.” I’m stuck driving a vehicle where the engine could fail randomly at any minute putting my family in danger and there’s no fix being offered right now despite the massive recall. Replace my engine!
