2023 Cadillac Escalade electrical system problems

“Since May 24, 2026, my 2023 Cadillac Escalade ESV has repeatedly experienced reduced engine power, check-engine warnings, multiple dashboard alerts and loss of propulsion. During one incident, the motor stopped responding, the vehicle lost power and came to a complete stop in the middle of a public roadway. This exposed me and surrounding motorists to a serious collision risk. Whether the shutdown resulted from an internal engine failure or an electrical/control-system malfunction remains UNKNOWN. OnStar documented recurring warnings and fault codes, including engine/transmission communication faults. The same condition returned after multiple dealership visits and repair attempts, including module resets/reprogramming. At times the check-engine light was no longer illuminated upon arrival, but the dangerous symptoms and OnStar reports had already occurred. An authorized Cadillac dealership blamed alleged aftermarket alarm/tracking equipment and proposed charging approximately $1,900 to remove it. I paid $250 for an independent inspection, which found no such aftermarket equipment and identified the questioned component as a genuine GM part. This incorrect…”

“On September 24, 2024, my 2023 Cadillac Escalade ESV stalled while I was driving in traffic and would not restart. I was unable to proceed normally at a green light, creating a risk of a rear-end or other collision. I have video footage of the vehicle unable to proceed. The authorized dealership documented a no-crank/no-start condition and found the engine assembly was seized. The engine assembly was replaced under warranty. Following the September 24 engine failure, the vehicle remained at the dealership through October 31, 2024 while the engine assembly was replaced under warranty. Earlier that same day, the dealership completed serial-data gateway module reprogramming and brake-system control-module programming related to brake-fluid leak detection. This is included as a factual chronology; I do not know whether that work was related to the engine seizure. Separately, on July 30, 2024, I received a “Replace Brake Pads” warning and heard grinding. The dealer found the driver-side front brake pads metal-on-metal and the wear sensor damaged. The dealer replaced the front brake pads, rotors, and wear sensor, and performed a brake-fluid exchange. These are…”

“Dear NHTSA Vehicle Safety, I would like to report a recurring safety issue involving the instrument cluster in my 2023 Cadillac Escalade ESV. Vehicle: 2023 Cadillac Escalade ESV VIN: [XXX] Current Mileage: Approximately 170,000 miles The digital instrument cluster/display directly behind the steering wheel intermittently goes completely black while the vehicle is in operation. When this occurs, I lose visibility of the speedometer, odometer, warning information, and other important driver information. The center navigation/infotainment display can remain operational while the driver’s instrument cluster is completely black. This condition originally began before the vehicle reached 70,000 miles. Initially, it occurred only occasionally and the instrument cluster would eventually turn back on by itself. The problem has progressively worsened and, particularly after approximately 120,000miles, the blackouts have become considerably more frequent. The vehicle has been brought to a Cadillac dealership. I was advised that insufficient battery power could be causing the problem. The battery was replaced and the vehicle software was updated. However, the instrument…”

“2023 Cadillac Escalade, 6.2L V8 (RPO L87). Subject of Recall 25V-274 and NHTSA investigation RQ26-001. Over the past year, this vehicle has been out of the shop only about 90 days total. The rest of the year it has been in dealer service at GM/Cadillac dealerships for a recurring, undiagnosed loss-of-power defect. It is currently in dealer service. FAILURE: The vehicle has suddenly lost all motive power on three separate occasions. Engine runs, vehicle loses all drive power, will not restart. Two events occurred at approximately 80 mph on an interstate highway. One occurred with children in the vehicle. The only warning is a “service rear axle” message that appears just before power loss. No diagnostic trouble code has isolated the fault. Root cause has not been diagnosed. REPAIR PATTERN: Six dealer visits across two Cadillac dealerships in one year. Interventions have included two battery replacements, a full engine replacement under Recall 25V-274, an approximately $1,500 charge categorized as diagnostic with no repair labor documented, and most recently a “wiring harness manipulation / re-wrap” performed over approximately 90 days. Dealer personnel described…”

“The vehicle has experienced the same safety issue on two separate occasions. While driving, the vehicle suddenly lost power and displayed a “Conditions Not Correct for Shift” warning message. During the incident, the vehicle became stuck in Drive and could not be shifted normally. The brakes also did not respond as expected, creating a significant safety hazard and making it difficult to maintain control of the vehicle. The failure occurred without warning and has happened more than once, raising concerns about the safety and reliability of the vehicle’s electrical, powertrain, and braking systems.”

“We were driving on an interstate in Indiana and the car jerked and then automatically went into neutral. We couldn’t accelerate or put the car back into drive. We had to get over 2 lanes and onto the shoulder. We were able to put the car in park once on the shoulder but the car would not turn on or off. We couldn’t do anything. All electronics were still running but the engine was not running. The emergency break went on as well. The car sat on the side of the road for 3 hours with the electronics going while waiting for a tow which then wore out the battery. Because the car switched on the emergency break, the towing company had a difficult time getting it up on the tow truck. There were no warning lights going off. We were going 75mph on a highway with my children in the car! Scariest thing ever. I can only imagine what could have happened. We were so lucky to not be hit on the highway trying to change lanes and not being able to accelerate. Then we had to sit on the side of a highway for 3 hours in 95 degree weather and we were 2.5 hours from home! After 3 hours, a tow truck finally showed up. My family had to take a taxi to the nearest dealership because…”
