Example complaints
Electrical system: “Brand new off dealer lot needed new battery. From that point forward the vehicle's electronics constantly malfunctioned. The dealer tried everything including working with Cadillac for new parts and suggestions to make the electrical system function normally. After three weeks of work, it still malfunctions and is dangerous to drive.”
NHTSA complaint #11331957, filed 2020-07, 2,046 milesTransmission and drivetrain: “Vehicle has a high-pitched whining noise when cold. Vehicle also has a transmission shutter problem at lower RPM. I do not think the two are related rather than two separate incidences. But cannot be confirmed that they are two separate. Maybe one problem only. I do have video of this happening. Cannot upload a video though.”
NHTSA complaint #11648582, filed 2025-03Back-over prevention (rear camera): “While reversing at a downward slope, sudden strong braking will occur. It does not always happen but when it does it is very alarming and loud. I’m guessing something is wrong with the Automatic Emergency Braking system. There is no warning prior to it happening. I fear these occurrences may cause an accident if I’m not wanting to brake at that moment. I have made Michael Hohl Dealership in Carson City NV aware of this issue but they don’t have a remedy for the problem.”
NHTSA complaint #11492475, filed 2022-11Engine: “2020 Cadillac XT6 with all options and new vehicle with less than 400 miles, fuel gauge indicator hash marks that show the level of fuel on the fuel gauge intermittently stop working upon engine startup. Dealer has already checked computer codes and found no error codes. Dealer states they have reset computers several times to correct this issue. Dangerous driving without knowing how much fuel is really in the fuel tank.”
