2021 Cadillac Escalade: engine knocking or ticking

Filed Oct 17, 2026 · Engine · TX

There is internal engine failure. Yes it is available for inspection. My safety as well as others were at risk when the engine started to fail, without warning, causing my car to jolt and briefly lose control of steering. If complete engine failure happened while driving, I would not have control over my car. My life and other's lives would severely be at risk. Car has been inspected and confirmed engine failure. Car is unable to be driven as we do not want to put anyone else at risk or make the problem worse. Car will be towed on Monday. There was absolutely no warning of this occurring. The symptoms first appeared while driving and the incident happened shortly after. There was a loud noise followed by my car being jerked traffic. I immediately pulled over until I could get my car safely home. When inspected the car was ticking with brief knocking noises. The ticking continued while the knocking noise became more abrupt and frequent.

There was knocking and stalling happening. I looked up the issue and saw that there was a recall on all 2021 Cadillac escalades with my exact engine. Unfortunately my vin did fall in the recall but I have the same issues and now my car has been at the service station for almost 2 weeks trying to figure this out and get the situation taken care of.

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.

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!

I purchased my Vehicle a little over a year ago and have had multiple engine repairs. The first issue started with the lifters going out. Shortly after the lifters were repaired, the engine seized, causing us to get an engine replacement. A few days after having the new engine, we had the same knocking/ticking noise coming from the engine which was also repaired once again. Then yesterday, 3/13/25, the engine started to knock/tick once again, but this time more aggressively. (New engine had only 15,000 miles.)
