After waiting months to get my vehicle checked for recall N252494000 NHTSA 25V274 I was told my vehicle passed inspection. When I asked to see the detailed results of the pico test I was told there are no detailed results and I was not shown anything proving my vehicle was tested and whether it passed or failed. My invoice states "Performed pico test test took multiple tries to complete having to unhook and reinstall pico to complete" which does not make me confident in the result. While talking to the service manager, he mentioned their original pico equipment was replaced by GMC after approximately 5 vehicles failed inspection. Since GMC sent the new equipment there have been no failed inspections. I can't find a way to express my concern to GMC or Cadillac online, that is what brought me here. This recall includes a safety risk serious enough to replace the vehicles engine, I want reassurance that the test was performed properly and my vehicle did not fail.

My engine all of a sudden went dead in the middle of an intersection. I was unable to put the vehicle in neutral and move it so it was stuck in the middle of an intersection until the tow truck arrived. In addition, it had to be dragged due to this issue - which I’m sure isn’t good for it.

Vehicle Make: Cadillac Vehicle Model: Escalade Model Year: 2022 Component(s) Affected: Engine, Fuel System, Powertrain, Vehicle Stability Control Incident Date: [Insert Date of Incident] Mileage at Time of Incident: [Insert Approximate Mileage] Summary of Complaint: While driving my 2022 Cadillac Escalade at approximately 70 mph on the highway, the vehicle suddenly lost all power and stability. This was due to an injector breaking off inside the engine, sending metal fragments into the camshaft, which subsequently locked the motor. This created an extremely dangerous situation as the vehicle became unresponsive and unstable at high speed. Just two days prior to this incident, the vehicle had been serviced by Quantrell Cadillac in Lexington, KY, where a recall repair involving the engine was performed. Despite that service, a catastrophic failure occurred almost immediately afterward. After the breakdown, Quantrell Cadillac attempted repairs over the course of three weeks. These repairs included replacing the injectors, camshaft, and other components, before eventually replacing the entire long block. However, upon picking up the vehicle, it is exhibiting the exact same failure symptoms again—making a popping noise, stalling the engine, and becoming unsafe to operate. This vehicle is clearly not safe to drive and poses a serious risk to myself, my passengers, and others on the road. There have already been multiple recalls related to this issue, indicating a broader systemic problem. We are requesting the NHTSA’s immediate assistance to investigate this safety issue and help us obtain a replacement vehicle that meets all applicable federal safety standards. This level of repeated engine failure & instability is completely unacceptable for any vehicle—especially one with such recent manufacturer service and recall repairs. When this stall occurs, the entire computer system & all safety features are shut down and collision avoidance is also disabled. Have viideo

I brought my Cadillac escalade in on two different instances where it stopped on me. One time it completely died, the other time it stopped and turn off, then needed to be restarted, with multiple instances. Both times the dealership told me it was related to the fuel pump, and they replaced it. Since then, I brought it in again saying it had random shakes and noises, and they claimed it does that when its in All Wheel Drive. This doesn't make sense. I have been using it in 2WD as recommended, and it still has the shakes and noises. In the past few weeks, the car stopped on my twice. One time I was making a left turn at a stop sign, the other, I was in the middle of an intersection. Now, I will not drive it out of fear for my family and own lives. I called to make an appointment at Autonation Cadillac West Palm Beach, and they said there is nothing that can be done since the engine needs to be replaced, and Cadillac still hasn't issued a remedy. They said for me to call Cadillac directly, which I did. Cadillac opened a case for me, and told me I would receive a call in 1-2 days. I called back on day 3, and was told that I have to wait for the person who was assigned to my case to call me. They informed me that it may take a while because Cadillac had cut the help center's (including recall department) work hours to save money, while they should have been increasing it during this massive recall. Now I have no car to drive my family in, and no response from Cadillac, with no resolution in site.

I am reporting a serious safety concern involving the 2022 Cadillac Escalade engine recall (GM 6.2L V8, RPO L87). My vehicle is used to tow a trailer regularly. The potential for engine failure due to defective connecting rods or crankshaft components poses a severe risk—especially while towing at highway speeds or on inclines. Loss of power while towing could compromise braking and control, endangering both myself and others. This concern should be escalated for owners who rely on these vehicles for towing. I am asking NHTSA to review how GM is prioritizing recall repairs for towing-use customers and to consider this a higher-risk category for resolution. My current situation is I have an appointment with Williamson Cadillac in Miami to scan the vehicle. If they determine its satisfactory to drive I will be towing a 7000 lb. trailer from Florida to Upstate New York. I'm very concerned that if I lose the engine I will have an exasperated safety issue because of the large trailer. There will be greatly reduced stopping power and limited room to pull off the highway. I need to be in Saratoga Springs with the trailer and its contents before May 19. Please advise, as I do not want to cause a fatal accident that could have been avoided.
