# 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 Cadillac Escalade IQL has a blind spot on the passenger side of the vehicle that is the worse I’ve ever experienced. The side mirror is set to view the vehicle on the side but even at the optimal safety settings I can’t see a car to my right unless I can see them out my passenger window or the turn signal camera is on.
NHTSA complaint 11754405 - Filed Mar 5, 2026Failure Mar 3, 2026New York, NYElectrical system, Fuel/propulsion system, Power train
Vehicle: 2026 Cadillac Escalade IQL (battery-electric SUV). At approximately 4,500 miles the vehicle began displaying battery/high-voltage system warnings and charging system errors. An earlier incident involved a critical battery warning instructing service. When presented to the dealership, the vehicle was initially described as potentially requiring extensive diagnostic disassembly. The dealership later reversed that position and stated the issue could be addressed by repeatedly "cycling the ignition" approximately 30–40 times. No permanent repair or engineering explanation was provided. More recently, during an attempted charging session, the vehicle terminated charging due to a battery system error and displayed a red warning indicator requesting service. This prevented the vehicle from accepting charge and therefore prevented normal operation. In a battery-electric vehicle, the ability to charge is the functional equivalent of refueling. When the vehicle refuses charging due to system errors, the vehicle becomes effectively unusable and raises potential propulsion and safety concerns. When the vehicle was presented again for service, the dealership stated they had been instructed by the manufacturer not to perform service because the vehicle may be retrieved by the manufacturer. As a result, the vehicle continues to exhibit battery/charging system faults without a confirmed repair path. The issue involves the electrical system, propulsion system, and charging capability. The vehicle remains under very low mileage and the condition has not been corrected.
