2020 Cadillac CT6 Review

Checking if a car has a recall is simple. Just type the car's VIN number into the NHTSA website (https://www.nhtsa.gov/recalls). If there's an unrepaired recall, you'll see it there.

If a recall shows up, just call your local car dealer. They'll know about the recall and will work with the car maker to fix it for free (if the recall happened within 10 years of the car being first sold).

Manufacturer Recall Number: 

N192279200

Manufactured from: 

2019-08-01 to 2019-09-09

Number of vehicles affected: 

81

Defect Description: 

General Motors LLC (GM) is recalling certain 2020 Cadillac CT6 vehicles equipped with dealer-installed accessory 20" x 8.50" wheels (RPO 5JO or SHH). The tire pressure monitoring system (TPMS) sensors use the incorrect wireless radio frequency and cannot illuminate the low pressure warning light when the tire pressure drops below the recommended level. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 138, "Tire Pressure Monitoring Systems."

Defect Consequence: 

Drivers may drive the vehicle with low tire pressure without a low tire pressure warning, negatively impacting the vehicle handling and increasing the risk of a crash.

Corrective Action: 

GM will notify owners, and dealers will replace all four TPMS sensors with the correct sensors, free of charge. The recall began December 3, 2019. Owners may contact GM customer service at 1-586-596-1733. GM's number for this recall is N192279200.
