I want to report several recurring issues with my 2024 Escalade transmission:Rough/Hard Shifting: Drivers experience jerky, clunking, or harsh shifting, especially when accelerating or decelerating.Transmission Slipping: The vehicle slipped between gears, impacting performance.Delayed Engagement: A delay or clunking sound when shifting from Park to Drive or Reverse.

Check engine light for P1467 on a 2021 CT4 V. This is for a "purge pump underspeed" issue. The issue is known on CT4 Cadillacs and has an active recall out: N242441120 Evaporative Emissions Purge Pump. This recall is only for the 2.0, LSY engines, but the much more uncommon 2.7, L3B engine in my car uses the same part # for the purge pump. It feels as though they are intentionally ignoring an equal emissions issue, but just on a smaller scale with the limited number of these engines they sold. What actions can I take?

My 2025 Cadillac Escalade ESV lost power and shut down while I was driving on the highway. The gas pedal stopped responding, and the vehicle would not restart afterward. This created a serious safety risk because the vehicle suddenly lost propulsion while driving in traffic. The vehicle is less than one year old and is already going to be on its third engine. The original engine was already replaced once before. The previous replacement engine was a brand-new GM engine with 0 miles, but it failed after only about 20,000 miles. Pepe Cadillac confirmed that this is the second replacement engine, which means the third engine counting the original engine. The dealer also confirmed that the engine locked up due to internal bearing material failure and needs to be replaced again. The repair order number is 140134. I am concerned this is a serious safety-related engine defect. A brand-new GM replacement engine should not lock up after only about 22,000 miles, especially while driving on the highway. I am also concerned that simply replacing the engine again may not fully address the safety and reliability issue with this vehicle. Cadillac Customer Care case number: 100539041.

service rear view camera message on randomly and then the camera goes blank. Independent service center diagnostic scan reported: FAULT B127B Rearview camera input signal circuit missing reference (Symptom 2B) - History DTC.

The contact owns a 2023 Cadillac XT5. The contact stated that the brake pedal would depress to the floorboard without warning. The contact had taken the vehicle to a dealer where a diagnostic was performed. The dealer received various diagnostic codes all related to the brake master cylinder. The contact was given a loaner vehicle and the dealer replaced both the brake master cylinder and the vehicle's battery. Despite the dealers repair, the contact refused to take possession of the vehicle due to the prior brake failure as she felt unsafe driving the vehicle. The manufacturer had yet to be notified of the failure. The vehicle was repaired. The failure mileage was 33,770.

My Cadillac Lyriq 1GYXPZRL1TZ601181 Has dents on the passenger roof rail. There are three dents one above the front door and 2 on the rear door. I discovered the dents on May 17, 2026 and I showed my local dealer on May 18, 2026. I have not been in a hail storm. My dealer said I need to file an insurance claim. Upon further research I have discovered that other owners have reported the same mysterious roof rail dents.

The driver-side headlight on my 2025 Cadillac Escalade failed while the vehicle was still under factory warranty. This is a critical safety component that significantly reduces nighttime visibility and creates a safety risk for both myself and other drivers on the road. The vehicle was inspected by an authorized GM/Cadillac service center, and the failure was confirmed. The warranty repair was approved; however, the replacement part has been placed on national backorder with no reasonable repair timeframe provided. I have now been dealing with this unresolved safety-related issue for nearly three weeks. Because the headlight assembly is a major safety component, the vehicle may not be safe or practical to operate at night or during poor weather conditions. Prior to the failure, there were warning/error messages related to the headlight system appearing on the dashboard. The problem has been reproduced and confirmed by the dealer. The failed component should be available for inspection upon request through the servicing dealership. My concern is not only the headlight failure itself, but also the inability of the manufacturer to provide timely replacement parts for a critical safety-related system on a nearly new vehicle. This creates an ongoing safety concern and prolonged loss of use of the vehicle.

On XXX, I was driving my 2025 Cadillac Escalade (6.2L engine) on [XXX] , at 55 mph in a construction zone. The right lane had a cement barrier one foot from the yellow line, eliminating any shoulder, and the left side had only a narrow berm before the median. Without any prior warning, I heard a loud “pop” and felt a jolt. Immediately, the check engine light illuminated, the vehicle went silent, and it began to coast. A message appeared instructing me to press “start” to start the vehicle. The battery remained operational, but the engine was unresponsive. I had not struck any object. I activated my hazard lights and, because I could not pull to the right due to the barrier, I coasted across lanes into the median. I could not exit the vehicle to safety due to location of the vehicle and the construction on both the north and southbound lanes of the highway as well as concrete barriers. The vehicle would not restart and could not be shifted into neutral, requiring specialized towing. Police responded and positioned a patrol car behind me due to the dangerous location. I could not safely exit the vehicle. The tow truck had to block the left lane to remove the vehicle. The vehicle was towed to Medina Auto Mall. The service technician advised this is “more likely than not” the same 6.2L engine failure subject to recall in 2021–2024 GM vehicles. However, the vehicle cannot be diagnosed for 3–4 weeks due to backlog. If confirmed, an engine replacement may take several months. The vehicle has approximately 11,500 miles, has run perfectly with no prior issues, and was properly maintained, including an oil change performed by the selling dealer, VanDevere Cadillac (Akron, Ohio). This sudden loss of propulsion on a highway in a construction zone created a serious safety risk, including the risk of a high-speed rear-end collision resulting in injuries to myself and other drivers. It was a frightening situation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

At lower speeds, especially after coasting, my car will lag for a few seconds before jerking forward. Also today I was coasting going about 25 mph and tried to accelerate and I pushed the pedal down and it wasn’t doing anything for several seconds then decided to start speeding up. No warning lights have come on. This has been happening for a bit but today was the first time I was concerned for my safety as I was out on a major highway
