2026 CADILLAC ESCALADE Complaints

On August 25, 2026, while driving my 2026 Cadillac Escalade, the vehicle experienced a sudden and catastrophic engine failure. The engine lost power and the vehicle became inoperable while I was on the road. There was no meaningful advance warning that would have allowed me to safely anticipate the failure. The sudden loss of engine power created a serious safety concern because the vehicle could no longer be driven normally or moved under its own power. The vehicle ultimately had to be transported by a specialty tow service to an authorized Cadillac dealership. The Cadillac dealership inspected the vehicle and advised me that there was a major internal engine failure involving the bottom end of the engine, including the crankshaft/rod-bearing area, and that the engine requires replacement. The vehicle was purchased brand new on December 31, 2025 with approximately 15 miles and suffered this major engine failure less than eight months after purchase. The vehicle had approximately 12,000 miles at the time of the failure. The vehicle is currently at the authorized Cadillac dealership and is available for inspection. Cadillac/GM has been notified of the failure, and a case has been opened with the manufacturer. My primary safety concern is that a major engine failure occurred suddenly while the vehicle was being driven. A sudden loss of propulsion in traffic could create a significant risk of a collision, particularly at highway speeds or in circumstances where the driver needs engine power to safely maneuver the vehicle.

First engine failed (6.2L) at 4900 miles and the was replaced. The second engine failed at 6000 miles and I am on my third engine now.

At 9,000 miles the engine on my 2026 Cadillac Escalade ESV started knocking and the dealership replaced it. They did not provide a loaner or a rental vehicle for the time the vehicle was at the shop. After the replacement, the new engine sounds the same and will probably needs replacing as well. After the fix I started getting electrical issues my rear right signal and taillight started acting up. Sometimes the rear signal doesn't work and another times the rear right taillight would stay on after turning the vehicle off and locking it.

My engine locked up with only 9k miles on it. Left me stranded in 109 degree heat. Had it towed to local dealer over 3 weeks ago they determined engine was bad and ordered new engine from GM but the engine is on back order. I need GM to buy my vehicle back so I can replace it I have nothing to drive.

Complete engine failure in 2026 Cadillac Escalade sport platinum with 3100 miles

The motor started making a ticking noise, then when we came to a stop, the motor died. I was able to get it started and get us home. As we made it home, the noise began to get worse. The next morning I planned to take it to the dealership. The car started and I began to drive. We entered the freeway and as traffic picked up, we came to a stop on the freeway. The engine died again. I was able to start it one more time and cotinued on until we got to the exit the dealership is on. At this point the car died again and we were unable to get it started. It left us stranded on the offramp. Car needed to be towed to dealership where it was discovered the engine had failed. Cadillac replaced the engine with a new one. This happened at 7100 miles.

I was driving on 35 mph road and first got a notification to service charging system, vehicle may stall, with the battery light on. Less than a mile after an alarm went off non stop stating engine overheating shut vehicle down immediately. Roadside mechanic came and discovered the serpentine belt failed. I have 1,100 miles on this car.

# NHTSA Complaint – 2026 Cadillac Escalade IQL My 2026 Cadillac Escalade IQL has experienced repeated "Service High Voltage System" warnings despite multiple warranty repair attempts involving the A/C/high-voltage thermal-management system. The vehicle is currently at an authorized Cadillac dealership and is available for inspection if requested. The problem first occurred in May 2026 at approximately 9,378 miles. The vehicle displayed "Service High Voltage System," "Maximum charge is limited to 69%," and "One-Pedal Driving Unavailable." The dealer documented DTC P0534, evacuated the refrigerant, flushed and recharged the A/C system, performed vehicle-wide programming, cleared the code, road-tested the vehicle, and returned it as operating properly. The problem recurred. On June 5, 2026, the vehicle was returned with "Service High Voltage System" displayed again. The dealer documented DTC P1C01, "NO OUTPUT FROM AC COMPRESSOR" and "INTERNAL OPEN IN COMPRESSOR MOTOR." The dealer replaced the A/C compressor and necessary parts, recharged the R-1234yf system, cleared the DTC, road-tested the vehicle, and documented proper operation. On August 8, 2026, "Service High Voltage System" appeared again while the vehicle was approximately three hours from home. Because the same high-voltage warning had returned after multiple prior repairs, including replacement of the A/C compressor, we did not feel comfortable driving the vehicle approximately three hours home. The problem was reported to Cadillac that day. The dealer retrieved the vehicle on August 13, and it remains at the dealership. My safety concern is the recurrence of a high-voltage system warning and previous charging restriction despite multiple dealer repair attempts. The repeated fault raises concern about the vehicle's ability to operate and charge reliably, particularly during travel. Prior occurrences were confirmed by an authorized Cadillac dealer, and the vehicle is currently available for inspection.

The night vision does not work. I told it to the dealer on 17 July they claimed they don’t know how to fix it. They blow it off and say that it’s because of the temperature but it’s not true. It wasn’t working at night when it was nice and cool. It wasn’t working during the day. It doesn’t work at all. They have a history of failing and general motors does not have a solid fix. They had this in their shop for six weeks and they still couldn’t figure out how to fix it. It still doesn’t work to this day. The temperatures have dropped at night, especially in the rain and that is not the problem. They lack of experience with night vision camera cameras is the problem and they are unable to fix it.

I was driving my NEW 2026 Cadillac Escalade down the highway when my engine froze up! It was damaged so bad that they replaced the engine. So obviously GM has not fixed this problem. They promised that the issue was fixed or I would have never bought this vehicle.
