2023 Cadillac Escalade

Transmission control module went out of the blue, caused limp mode on the highway and barely got off. Damaged the Transmission, had to replace by cadillac. 2 weeks later after i got the car back, blew 3 fuses and the starter while driving. Had to get towed back over 100 miles. 3 days later the engine completely blew and they had to replace it. this was the second time this happened, first since ive owned it.

The engine/powertrain malfunctioned on my 2023 Cadillac Escalade at approximately 29,434 miles, ultimately requiring complete engine replacement. During the engine repair, the Cadillac technician also discovered that the transmission cooler lines were leaking fluid. The dealership replaced all of the affected transmission cooler lines as part of the repair.The original failed engine was removed by the Cadillac dealership, so I do not know whether GM/Cadillac retained it. The failure involved the vehicle’s engine and created concern about the possibility of sudden loss of propulsion or engine failure while driving. Because this is a large vehicle routinely operated on public roads and highways, an unexpected loss of engine power could significantly reduce my ability to safely accelerate, merge, or move the vehicle out of traffic. Fortunately, I brought the vehicle in for service after noticing the abnormal engine noise before a complete failure occurred while driving. Yes. Heritage Cadillac inspected and diagnosed the vehicle. The dealership documented my complaint of a “weird noise on start up” that continued until approximately 10 MPH. The technician removed the valve covers and inspected the rocker arms and pushrods. The dealership ultimately determined that an engine replacement was necessary and replaced the engine under warranty. Yes. The vehicle was inspected and repaired by Heritage Cadillac, an authorized Cadillac dealership. The dealership diagnosed the engine issue and replaced the complete engine. During the repair process, the technician also discovered leaking transmission cooler lines. I did not receive a warning lamp or dashboard message alerting me to an engine problem. The primary symptom was an abnormal engine noise shortly after startup that continued during initial acceleration to approximately 10 MPH. This prompted me to bring the vehicle to Heritage Cadillac for inspection. The dealer documented this symptom on the repair order.

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 fix as “manipulation fixed it” — which is not a diagnosed repair. On at least one return of the vehicle, dealer personnel stated in the presence of a witness that they were not certain the defect had been fixed. The “service rear axle” warning returned within three days of the most recent repair. POST-RECALL: The engine was replaced under Recall 25V-274 and the loss-of-power failures continued afterward. This is directly relevant to RQ26-001, examining post-recall-remedy failures.

2023 Cadillac Escalade Sport Platinum with 6.2L L87 V8 suffered catastrophic engine failure on 6/20/2026 at approximately 38,658 miles. Vehicle had GM recall N252494000 performed at Coulter Cadillac in Phoenix, AZ on 12/3/2025. Engine reportedly passed GM recall inspection and received oil-related remedy rather than engine replacement. Approximately six months later, while driving on I-17 near Black Canyon City, AZ at highway speed on a 75 mph interstate, the engine suddenly shut down with no warning signs or alerts. Vehicle shifted to neutral and lost all propulsion. There were no prior check-engine lights, oil-pressure warnings, reduced-power warnings, abnormal noises, or other alerts before failure. I was traveling with my family of four plus our dog in approximately 105°F heat at the start of a road trip. I was able to maneuver to the shoulder, but the sudden loss of propulsion at highway speed created a serious safety risk. We were stranded roadside for nearly one hour in a remote area. Earnhardt Cadillac in Scottsdale, AZ diagnosed crank bearing failure. GM/Cadillac has indicated the proposed repair is installation of a refurbished/remanufactured replacement engine. I am concerned this failure occurred after the recall remedy had already been completed and appears consistent with the L87 crankshaft/connecting rod/bearing failures and post-remedy failures under NHTSA review. Cadillac case number is 103635161.

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.

5/7/2026: Travelling on freeway with son at 70-75mph, vehicle shifted itself into Neutral causing loss of acceleration and a message stating vehicle engine needed to be restarted. I had to navigate crossing multiple lanes of traffic to safely exit while quickly loosing speed. Was able to safely exit the freeway and come to a complete stop to restart the engine and resume normal driving. 10 minutes later, the vehicle repeated this causing yet another safety issues. Vehicle has been at the dealership since 5/8 and as of this report 5/12, the technicians are reporting that they have not been able to replicate the problem. I am in fear of the safety of myself and my family and am very hesitant about accepting the vehicle back without a proper diagnosis or repair.

Vehicle: 2023 Cadillac Escalade (VIN: [XXX] ) Dealer: Cadillac Pasadena Case Number (GM Corporate): XXX Refusal to perform a mandatory Federal Safety Recall remedy. Details: 1. My vehicle is currently under Safety Recall XXX(L87 Engine Loss of Propulsion). I experienced a loss of propulsion and brought the vehicle to Cadillac Pasadena. 2 The dealership technician confirmed the engine is exhibiting "abnormal noise (lifter clatter on both banks) and active misfires." 3 The dealership claims they cannot complete the mandatory PicoScope diagnostic test for the recall because the engine condition (misfires/noise) interferes with the equipment. 4 Under GM Special Coverage XXX, if the engine cannot be safely tested due to internal mechanical failure within the recall population, GM is mandated to cover the diagnostic teardown and full engine assembly replacement at no cost to the consumer. 5 The dealership is refusing to authorize the teardown under the GM Special Coverage code and is instead pressuring me to pay myself. 6 The dealership has stopped responding to my written inquiries (sent March 18th and 19th) and refuses to provide a loaner vehicle, despite the vehicle being officially "unsafe to drive" due to the open safety recall. I am asking you to requre Immediate authorization of engine teardown and full engine assembly replacement under GM Special Coverage XXXat $0 cost to me, and provision of a loaner vehicle as required for safety recall grounding.

On September 8, 2024, while traveling approximately 75 mph on Interstate 4 with my wife and five children, this 2023 Cadillac Escalade experienced a sudden catastrophic loss of engine power following a hard shift. Steering, braking assist, and acceleration were effectively lost and the vehicle shifted into neutral without warning. We were nearly struck by a tractor-trailer while attempting to reach the shoulder and were stranded on the highway in unsafe heat for over an hour without roadside assistance. A dealership inspection confirmed catastrophic internal engine failure involving metal debris and spun bearings, requiring complete engine replacement and related component repairs under manufacturer direction. The vehicle was out of service for approximately 15 days. The failed components and repair documentation are available for inspection through the dealer and manufacturer. No prior warning lights or messages were present before the initial failure. On February 8, 2026, the replacement engine experienced a second sudden loss-of-power event. The day before, the vehicle briefly lost propulsion near 40 mph approaching a stoplight and restarted with difficulty. The following day, while backing from a parking space into an active roadway, the vehicle again lost propulsion and became disabled, nearly resulting in a collision with an approaching truck while surrounding traffic was forced to stop. This repeat failure of the engine/powertrain system has been reproduced and confirmed by a dealership and previously inspected by the manufacturer. The recurring sudden loss of propulsion without adequate warning creates a serious and ongoing safety hazard to occupants and surrounding motorists. The failed components and vehicle remain available for inspection upon request.

Received a recall letter that stated the engine in my 2023 escalade with roughly 49,000 miles on it at the time. Has problems with the engine breaking down and shutting the entire vehicle off. Took the car to the dealer to fix per the recall letter. They stated they only needed to replace an oil cap and put better oil in the car, and not replace the engine as stated in the recall letter. About two weeks later the transmission started to slip and the car would not go over 50 MPH, in addition it would switch automatically into 4wd and get stuck in 4wd. Took the car back to the dealership they did not replace transmission they stated it may have something to do with the recall or an electrical issue. About 8,000 miles later I was driving on the highway taking kids to school and the entire vehicle just shut down completely, I could not brake, steer, control the car in anyway possible. I was riding what felt like a death trap. I was so scared for my family and myself, the car came to a stop on its own pretty drastically. I thought I was going to get slammed into or hit the car in front of me. Luckily I was not hit. The car prompted to push the start button, I tried to start the car, nothing. There was still music playing but the screens were all black, also the engine did not turn over at all. I could not put on my hazards either. I called a tow truck while sitting there and got the car towed to the dealership. The dealership took 3 days to get back to me and stated it was the engine and they are going to have to replace it with a new engine. In addition they would not provide me with a time frame at all, or a temporary vehicle to take my kids to school in. I feel this should be illegal with what has happened to me, I got regular oil changes and maintenance done. If they are still using this engine someone will end up dying from this poorly engineered engine and car. Cadillac once had a great reputation, I regret putting my kids and my life into this automobile.
