2021 Cadillac Escalade ESV electrical problems

Filed Feb 7, 2026 · Body, Electrical · CT

I am experiencing an ongoing issue with my vehicle’s rear passenger door. The door frequently cannot be opened from either the inside or the outside. At first, I believed the problem was related to the child safety lock. However, even after confirming that the child safety lock is fully disengaged, the door still fails to open from both inside and outside. Occasionally, after turning the vehicle off and restarting it several times, the door will open normally. However, the problem returns randomly, and the door appears to lock itself again without warning. Based on these symptoms, I strongly suspect a defect or malfunction in the rear door latch or door lock actuator. This issue presents a significant safety concern, as it can prevent passengers from exiting the vehicle when needed. I am requesting a thorough inspection and proper repair to permanently resolve this issue. Thank you for your attention to this matter.

On 12/18/2025 at approximately 73,097 miles, while driving on I-75 near Wildwood, Florida at about 75 mph, the vehicle experienced a sudden powertrain failure. The engine became seized/locked, the vehicle progressively lost power, and there were abnormal/loud mechanical noises. I was able to avoid a crash, but the event created a safety risk due to loss of propulsion at interstate speed. No accident occurred. The vehicle later received an engine replacement at Plaza Cadillac (Leesburg, FL). Dealer paperwork indicates completion on 01/07/2026, and the vehicle was returned to me on 02/02/2026. After the engine replacement, the vehicle displays safety-related warnings including: “Service Transmission Now – Unable to Shift Soon” “Service Electric Parking Brake” Because of these warnings, I am not driving the vehicle. The dealer plans to tow the vehicle in for inspection. In addition, the dealership has stated in writing that they typically clear diagnostic codes for test driving and that no post-repair/post-road-test diagnostic scan reports are saved or printed, meaning there may be limited retained documentation verifying that all modules were fault-free at release after the engine replacement. Cadillac case reference: Cadillac Care Center Service Request #88422536. I consent to sharing this complaint and vehicle details with the manufacturer.

My wife was driving my kids to their nana and papas house when the vehicle loss power. The vehicle started to have a knocking noise and started to vibrate towards the engine compartment. The dash lit up like a Christmas tree. We took the vehicle to a local mechanic and he suggested that we might need a tune up. We purchased 8 brand new spark plugs, spark plug wires and 8 brand new coil packs. The local mechanic installed all of the new parts and the vehicle acted just like it was before the tune up. We then took the vehicle to Boyd Cadillac in Henderson,NC. Tim, who is our service provider, contacted us and told us that we had severe engine failure. His recommendation was a complete engine install. We have used Boyd Cadillac, Tim on several occasions. We had an alternator replacement done which was not under warranty. We had lifters replaced under warranty around the 50k mile mark.

The contact owns a 2021 Cadillac Escalade ESV. The contact stated that the check engine warning light was displayed on the instrument panel with an abnormal whining sound coming from the vehicle. The contact took the vehicle to the dealer and was informed that the battery needed to be replaced. The battery was replaced; however, the check engine warning light illuminated the following day. The contact stated that while driving at 45 MPH, the vehicle started to jerk abnormally while depressing the accelerator pedal, and the vehicle shut off in the middle of the highway. Due to the failure, the vehicle was towed back to the dealer, where it remained unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 71,000.

Car died in the middle of road. You pump the gas, nothing. This happened twice. Once at about 30000 miles and then at 60000 miles. The dealer had to replace a module or electrical box for fuel pump.

Twice in the last 6 months the vehicle doors have locked at random while the key was inside the vehicle. Both times, my children were trapped in the vehicle exposed to potential heat issues. Fortunately, in both cases the doors were able to be opened through another door that was still open one time and by hitting the unlock button through a slightly rolled down window. Breaking the glass was the next option. This is a serious safety defect that is putting young children and pets at risk for heat injury or death. There are no indications as to why this started, no warnings displayed, and seems to occur at random. Disabling autolock features does not resolve the issue meaning some glitch or equipment failure is causing the doors to lock despite all autolock features turned off.

The rear, third row passenger vent will occasionally put out very hot air. This results in the back seats becoming overheated especially on hot days. This is putting my young children at risk for heat related injuries and possibly death as the front seats remain cooled but the rear compartment heats up substantially. The dealer was unable to reproduce the problem but it occurs at random so reproduction is difficult. No error codes are shown. The problem will resolve once the vehicle is shut off for an extended period of time but will then recur at random putting all rear passengers that are sleeping or too young to complain about the temperature at significant risk.

After driving about 3 hours, the TPMS system displays an error saying the module has failed. This occurs with OEM and aftermarket TPMS sensors. The error clears itself after the vehicle is parked for > 1 hour. The dealer has found no fault in the sensors but would not test the system otherwise. Losing TPMS readings during long drives is unsafe and could lead to an accident or damage to the vehicle if tire damage occurs while the system is malfunctioning.

I had my 2021 Cadillac Escalade esv vehicle service twice at the dealership of purchase regarding the vehicle gear shifting on its own and dragging. The service advisor said they couldn’t find a problem with the vehicle. He told bring it back if it does it again. [XXX] the problem occurred twice in one day. I thought maybe I had bumped it out of gear inadvertently. I started looking down every time I touched the gear shift to assure it was the correct setting. I booked appointment service via my phone 2/11/24 for [XXX] service. I was at the car wash drive thru [XXX] my vehicle was in neutral coming off the conveyor belt. As I attempted to pressed the shift toggle to change gear my vehicle made a weird noise . I never got the chance to shift to drive. Grinding pulling noise like it was stuck. My vehicle shot forward like something catapulted. My vehicle hit another vehicle before hitting a wall. My air front air bag never deployed. The collision avoidance did not engage or signal. I don’t understand how a vehicle can shift it self in and out of gear on its own. If I’m doing 25 mile the vehicle shouldn’t make rpm act like I’m doing 100. Also if I’m doing 70 mile the vehicle should not shift down while pressing the gas pedal. Had they listened to me and took what I was saying seriously this would have never happened.
