2024 Cadillac Escalade ESV

On August 17, 2026, at approximately 96,685 miles, my 2024 Cadillac Escalade ESV equipped with the 6.2L L87 V8 engine lost motive power while I was driving on Highway 101 in California. The vehicle stalled, I pulled over, and I was unable to restart it. The vehicle was towed to the dealer. The dealer diagnosed a seized engine that would not rotate, with metal contamination in the oil system and internal engine damage caused by a failed bearing. During teardown, the dealer specifically documented that the rod bearing failed and caused the engine seizure. This vehicle had previously received the GM L87 engine recall remedy on August 11, 2025, at approximately 47,987 miles. The dealer documented that the required PicoScope test passed and that the vehicle was operating normally at that time. The engine failure occurred approximately 48,698 miles after the recall remedy. GM subsequently replaced the engine under warranty. I am reporting this as a safety-related loss-of-motive-power event because the engine failed while the vehicle was traveling on a major highway and could not be restarted. I request that NHTSA consider this incident in connection with Recall 25V-274 and Recall Query RQ26001 and evaluate whether the recall remedy adequately identifies L87 engines that remain at risk of subsequent failure.

The Forward Collision Warning system will shut off while driving and an error message will appear. Also, the entire dashboard and radio goes blank and restarts while driving. Also, the backup camera often does not work, instead of an image the screen will flash purple then go black without any image at all. We have brought the car in multiple times for repair, the dealer has had the car for well over a month and it is still not repaired.

I own a 2024 Cadillac Escalade ESV equipped with GM's 6.2L L87 V8 engine. The recall remedy for GM Safety Recall N252494000 (NHTSA Campaign No. 25V-274) was completed on April 17, 2026, at approximately 48,905 miles. Only approximately 2,347 miles later, on June 15, 2026, at approximately 51,252 miles, the engine experienced a severe malfunction while I was driving with passengers. Without warning, the engine began running extremely rough with severe vibration and shaking. The Check Engine Light began flashing, and Service StabiliTrak and Service Traction Control warnings appeared. A few minutes after I stopped the engine, it would not restart. I found no measurable engine oil on the dipstick. When the engine was started again, a large amount of blue smoke was emitted from the exhaust, while the engine continued running extremely rough. GM's official MyCadillac application displayed critical warnings for the Engine & Transmission System, Emissions System, Transmission System, and Variable Valve Timing (VVT) System. GM ultimately determined that the engine required complete replacement under warranty. Despite completion of GM Safety Recall N252494000 (NHTSA Campaign No. 25V-274), the engine required complete replacement only approximately 2,347 miles later. The replacement engine remains on backorder. I understand that NHTSA has opened Recall Query RQ26001 regarding post-remedy L87 engine failures. Because my vehicle experienced a post-remedy engine failure only approximately 2,347 miles after completion of the recall repair, I respectfully request that this complaint be included as part of Recall Query RQ26001. I have preserved photographs, videos, diagnostic screenshots, and repair records.

The contact owns a 2024 Cadillac Escalade ESV. The contact stated that while attempting to start the vehicle, there was an abnormal ticking sound coming from the engine. The vehicle was taken to the dealer where it was diagnosed and determined that the engine needed to replaced. The vehicle was not repaired. The VIN was not included in NHTSA Campaign Number: 25V274000 (ENGINE and ENGINE COOLING). The manufacturer was not notified of the failure. The failure mileage was 20,000.

I had the recall performed on my ESV in December, but driving home from [XXX] my dash indicated that I needed to push start. I did and it slowly died. I had it towed to Andrews Cadillac where it was purchased and I learned that my engine locked up. It is being completely replaced with 41,000 miles. Thankfully it was under warranty but apparently this is an ongoing issue with GM and the 6.2 liter engines. I won’t have my car for weeks while I await a new engine.

The contact owns a 2024 Cadillac Escalade ESV. The contact stated that while driving approximately 60 MPH, the vehicle stalled. There was no warning light illuminated. The contact had the vehicle towed to a local dealer, where it was diagnosed and determined that the engine had failed and needed to be replaced. The contact was informed that the 6.2-liter gasoline engine was on a national back order. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 15,000.

There was a vibration in the rear then the wheel flew across the 4 lane hwy. Wheel completely detached from the SUV.

Lifter failure. Camshaft damage and failure. Those were replaced. Within two weeks later: Complete engine failure. Seized while driving on interstate in traffic. Was stranded on Interstate near DFW airport. Required complete engine replacement. There was no warning before it seized.

I was driving on the highway with the cruise control set at 70 mph. I heard a loud knocking/grinding noise that sounded like an old 1970s car with a blown engine. Turns out it was my Cadillac Escalade. I pulled off the highway and the grinding noise was very pronounced and worsened if you pushed the gas. I was 1 mile away from a Cadillac dealer (by God's good grace!) and managed to drive there. I have been told it is a catastrophic engine failure and the car has been in the shop 40 days waiting for an engine. GM/Cadillac cannot give me any estimate of when an engine will be available.

**Exhaust Emissions System Issues** I have visited the dealership four times for the same problem that was fixed. Unfortunately, the system broke again within three days of each visit. This repeated issue has resulted in a significant amount of wasted time and effort.

The vehicle suddenly broke down on the road putting my life at risk, resulting into having it towed. Since then the engine light keeps coming on consistently after repairs. It has been consistent visit to the shop without a permanent solution. It has been in the shop for a month and is still in the shop. They’ve been unable to find the problem until they informed me a new engine will be needed. I’ve attached invoices for consistent visit to the shop for the same problem involving the engine and the engine light always on. I have more documents available but I’m unable to upload due to the size but can be presented on request.

On August 5, while driving on I-79 at 78 mph, our Escalade suddenly and completely shut off. The entire system failed — no power, no control — while our three children were in the car. This is the second GM vehicle we’ve owned to do this. Our previous Yukon Denali also shut off twice at highway speeds before we got rid of it out of fear for our safety. We reached out about the Escalade recall and were assured two months ago that our vehicle was not affected. Clearly, that assurance was wrong — and we’re now reliving the exact same terrifying situation with yet another GM vehicle. My kids are traumatized and refuse to get back in the car. Frankly, I don’t blame them.
