On XXX, I picked up my 2025 Cadillac Escalade ESV, VIN [XXX], from Open Road Cadillac after a replacement 6.2L V8 engine had been installed following failure of the original engine. Approximately one mile after leaving the dealership, the engine temperature rose to approximately 297°F. The vehicle displayed a critical oil-pressure/no-oil warning, coolant leaked from the vehicle, and the replacement engine produced a loud metallic knocking/clanking sound and had difficulty starting. The vehicle could not be safely operated and was returned to the dealership. The dealership subsequently advised me that a coolant hose/component had come off and caused the coolant loss. I was later advised that the vehicle was repaired, had completed approximately a 15-mile road test, and was ready for pickup. My safety concern remains that I have not been provided documentation showing that the oil-pressure warning and loud metallic engine knock were fully diagnosed or that internal engine damage caused by the extreme overheating and/or oil-pressure event was ruled out. I have video evidence documenting the knocking sound and photographs documenting the incident. Cadillac/GM has an open executive case concerning this vehicle, Case #106602304. I have requested GM technical/field-engineer review before accepting the vehicle for normal operation. I am reporting this incident because NHTSA currently has Engineering Analysis EA26005 open concerning loss of motive power and L87 6.2L engine failures, including failures involving replacement engines and engines manufactured after the production period covered by the earlier recall. I am requesting that this complaint and VIN be reviewed in connection with that investigation. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2025 Cadillac Escalade ESV went into the dealership for routine maintenance and several software updates were applied to vehicle along with an oil and filter change on 17 February. The software took multiple times to load and I took the vehicle home on 20 February. Later that day after picking up my children from school an error popped up on the dash that stated Service Leveling System and Vehicle Too Low Drive with Caution. Shortly after on the way home the ride height system made a crunching noise after I parked and got out of the vehicle to get gas. It felt like something mechanical wasn't working in the suspension. I dropped it back off at the dealership Monday 23 February. I picked up the vehicle later that day and the same error popped up again. We then gave it back to the dealership on the 24th of February to resolve and they kept if for over a week and were unable to determine root cause of the issue as of 2 March. The error code was reset by the dealership and was told to notify them again if it happens a third time. I believe there is a software issue that is causing problems with the adaptive air ride suspension.

While driving at approximately 40 MPH there was a loud pop and the panorama sunroof shattered. There were other cars traveling at the same speed or less, but nothing struck the vehicle to cause the glass to shatter. The glass did not immediately give way, but had it, there were passengers that would have been impacted. The roof was inspected by the dealership but is no longer available for inspection as the dealership could not provide a loaner or rental vehicle. There was no warning. The temperature was mild. This is not about the repair expense or time involved but about the safety or the panorama sunroof.
