What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
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.
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.
My abs & stability track system is malfunctioning which almost caused me to lose control of my vehicle. I heard there was a recall on the 2019 & 2020 braking system. I found that info online after doing a search
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.
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.
[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.
Several unknown warning lights were illuminated on the instrument panel. The contact stated that after purchasing the vehicle, the vehicle started shaking abnormally while driving. The contact pulled over the right side of the road and turned off the vehicle.
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.
