2 safety recalls, most serious first
1. Lights
What's wrong, in plain English: Headlights, tail lights or turn signals may not work, making the car hard to see. The Park/Position lights may be excessively bright. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
What could happen: The excessive brightness may affect the vision of other drivers, increasing the risk of a crash.
The fix: Dealers will install right and left side in-line headlight jumper harnesses, free of charge. Owner notification letters were mailed November 3, 2021. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is N162016079.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2017 CT6 HYBRID.
- Book a repair at any authorized Cadillac dealer. Quote NHTSA campaign 21V759000 (manufacturer code N162016079).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-458-8006.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
