2020 Cadillac XT4

A PROBLEM WITH SOMETHING INTERNAL CAUSING THE HAZARD LIGHTS TO COME ON WHEN THE CAR IS NOT TURNED ON. REPEATED ATTEMPTS TO TURN THE HAZARD LIGHTS OFF DON'T WORK. THEY STAY ON AND DO NOT STOP UNTIL THE BATTERY WAS TOTALLY DEAD. I DON'T KNOW WHICH SYSTEMS ARE AFFECTED OR TRIGGER THE HAZARD LIGHTS TO COME ON. AAA WAS SUMMONED FOR BATTERY SERVICE. BATTERY WAS REPLACED BUT THE ISSUE WAS NOT FIXED.

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)

I have a Cadillac XT4 with 33K miles. Last week my battery was dead. As a senior citizen who is a widow it is important that I not be stuck in a situation where I cannot get my car started which is why I am diligent with my maintenance. After I finally got my car to the dealership where I was charged $425 for the battery I started to investigate other owners complaints of this nature. Based on simple Google searches, It appears that the XT4 has alot of battery problems. This puts the driver in a dangerous situation. I called GM helpdesk who said that there is no recall at this time, but if there is one that I will be notified. Why wait? I know this may not seem like a huge safety problem to you like airbags etc, but the battery being dead with no prior indication puts people in a dangerous situation. I appreciate what your agency does and thank you for reading this

I have a 2020 cadillac xt4. When I first purchased the car in 2021, it already needed a new battery. Since owning the vehicle, I've had to change the battery two times already with 3 years. When I go to start the car (push start) sometimes the car wouldn't turn over or turn on and my dash board would illuminate stating service stabilitrak. Sometimes it would take like 5-8 tries before the car turned on. When it did turn on, my check engine light came on, I couldn't accelerate beyond 43 miles, my braking system was not working and a lot of features on my car stopped working like the lane assistant didn't work, and neither did my cruise control, or emergency braking. Took it to O'Reilly and bought a new battery. Once I installed the new battery, the check engine light disappeared and the car started driving fine again.
