2020 Cadillac XT4

On April 9, 2021, the Office of Defects Investigations (ODI) opened PE21-010 to investigate instances of air bag malfunction indicator light (MIL) illumination and potential for frontal air bag non-deployment in several vehicles manufactured by General Motors (GM). The vehicles included model year (MY) 2020 through 2021 CT4 and CT5 passenger cars, Sierra and Silverado trucks (1500/2500/3500 models), XT4 and MY 2021 Escalade, Suburban, Tahoe, Yukon SUVs.Technical Service Bulletin (TSB) 21-NA-005, issued in March 2021, addresses air bag MIL illumination with diagnostic trouble codes (DTCs) B0001-1B or B0012-0D. It cites rust particles in the connection terminal interface of the driver air bag inflator housing as the cause of the air bag MIL illumination. Illumination of the air bag MIL under these circumstances may result in a non-deployment of the frontal driver air bag during a frontal collision and increased risk of injury to the driver.GM stated a correlation exists between production delays due to the pandemic shutdown and premature corrosion initiation on the surface of the air bag inflator housing, which, in some cases, caused rust development during a seven (7) month period of vehicle production. In the rare instance when a rust particle dislodges from the driver air bag inflator housing and enters the air bag connector prior to assembly, an intermittent resistance spike at the air bag connector may result. The condition generates excessive resistance in the air bag electrical system when the steering wheel horn cover is manipulated or the steering wheel is turned. This excessive resistance is momentary. A crash commanding air bag deployment would need to occur exactly when the momentary excessive resistance occurs. Thus, there is a very low likelihood the hazard will present a risk during a crash of sufficient severity to warrant a commanded deployment. This failure mechanism occurs early in life and results in an air bag MIL illumination that corresponds to a DTC warning the driver that the vehicle requires service. The vehicle's air bag remains functional while the MIL is illuminated, and the DTC is present.Once the connection of the driver air bag module to the clockspring is made at the plant, or at the dealership for service, there is no longer an opportunity for rust migration into the connection point. The connector is sealed and has gold terminals, eliminating the expectation of fretting corrosion. All subject vehicles passed standard corrosion validation testing for extensive corrosion with no issue of air bag non-deployment.There is a low rate of occurrence: 1.41 incidents per thousand vehicles (IPTV) for all related occurrences, and 0.04 IPTV for occurrences with a mention of visible rust and/or corrosion on the air bag inflator housing. The average occurrence mileage for the subject vehicles is approximately 2,100. Every occurrence related to the alleged defect experienced an air bag MIL illumination and there are no verified allegations of air bag non-deployment within all data sources.To date, there have been no reported fires, crashes, injuries, or fatalities related to this issue. In view of the low rate, and the nature of early-life failure, the high detectability of failures, and low potential hazard to drivers, this Preliminary Evaluation (PE) is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.Review the ODI reports cited above at nhtsa.gov under the following identification numbers: 11537927, 11528888, 11525020, 11521401, 11506057, 11493107, 11486767, 11441525, 11433146, 11425658, 11423440, 11385267, 11376429, 11373466, 11366995.

The contact owns a 2020 Cadillac XT4. The contact stated that upon starting the vehicle, the check engine warning light illuminated. The vehicle was taken to Auto Zone, where it was diagnosed and determined that the EVAP pump (Evaporative Emissions System) was leaking. The vehicle was not taken to the dealer or to an independent mechanic. The vehicle was not repaired. Additionally, the contact noticed that the fuel mileage of the vehicle was fluctuating. The contact stated that the vehicle made an abnormal sputtering sound and delayed starting while pressing the Push to Start button. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was 56,400.

Rear camera/360 camera works intermittently. Vehicle has been recalled for this exact problem and was taken to dealership for correction. Camera became inoperative again and a camera replacement was paid for out of pocket around early 2025. 6 months later, the issue has started again and camera is inoperative when reversing.

I was in slow traffic and my check engine light came on then the parking brake engaged. My car stopped and I could not disengage the parking brake so the car could shift gears. I turned my car off for several minutes. When I turned the car back on, the check engine light and parking brake turned off and I was able to shift gears again.

The contact owns a 2020 Cadillac XT4. The contact stated that while driving at an undisclosed speed on the highway, the Forward Collision Avoidance feature indicated that there were pedestrians ahead on the road, but there were no pedestrians on the road. The contact stated that later, while pedestrians were present, the Forward Collision Avoidance feature failed to operate as designed. The vehicle was taken to the dealer; however, the dealer was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 73,000.

The recall i have listed below is a safety issue regarding the vehicles inability to properly stop for pedestrians, objects, traffic, backing up due to camera / software failure. This was fixed in 2022 on my car per the recall. everything worked great until it started happening again 12/2024 and they replaced the module now at an expense to me. it seemed to work for about 1 month and Now its 3/2025 and i continue to have this issue intermittently keep happening and they can't seem to find the problem. It happened in January, Feb, and March of this year. [XXX] — Cadillac XT4 rearview camera failures have caused a recall of more than 10,000 SUVs equipped with optional Surround Vision features. Recalled are 2019-2020 Cadillac XT4 vehicles with video processing modules (VPM) that may lose communication with the rearview cameras. This will cause the rearview camera image to fail. GM opened an investigation in August following backup camera failures in 2020 Cadillac XT4 SUVs. The automaker found increased warranty claims for camera failures on 2019 and 2020 XT4s. GM also received nearly 850 field reports between December 28, 2018, to September 19, 2022. According to General Motors, the problem with the video processing module is a software anomaly that allows the communication issues. A Cadillac XT4 driver may notice a problem if the backup camera image is replaced with a black or blue screen. Cadillac expects to mail XT4 recall letters January 9, 2022, and dealers will update the processing modules. In addition, the video processing modules will be replaced in 2019 Cadillac XT4 SUVs. Cadillac XT4 owners who want to learn more about the recall should call 800-458-8006 and ask about rearview camera image recall number N222373320. from this website: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
