Driving my 2021 Escalade on interstate and engine began emitting sudden, loud metallic tapping. Oil pressure dropped off and a reduced power warning came on HUD. Acceleration dropped off, forcing him to coast dangerously across three lanes of traffic to the shoulder. Coasted to dealership—-somehow the VIN didn’t fall within the 2021-2024 recall despite exhibiting the exact same failure. Catastrophic engine failure needing full engine replacement.

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 the federal safety agency investigation ongoing.
