Campaign: 19V731000

TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS

Summary

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."

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.

Remedy

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.

Additional Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Consequence

The vehicle was shifting harshly and my wheels were experiencing lock up while in motion which was very dangerous. I experienced this on the parkway as well as streets and almost had a few accidents due to this problem. I drive my wife and children in this vehicle. Our safety and lives were put at risk. There were no warning lamps to advise of troubles. I also have some computer problems that are supposed to be addressed. Gm dealer has had my car for four months and have tried to replace valve four times and all four times the part they received was defective and unsuccessful. I have made many calls to GM and they are giving me the run around. Now they want to replace the entire transmission but wanted to use aftermarket part which more than likely is also defective. They are having a hard time obtaining a new transmission and also advised me I would be responsible for the cost of this replacement when they get a new transmission. At this point I am not willing to risk mine or my families life by driving this car after they try to replace transmission. Iโ€™m also not willing or able to pay for this repair that was no fault of mine. I am not sure how to proceed in getting them to replace entire vehicle but that is the safest option at this point.

ON FRIDAY, NOVEMBER 13, 2020 I WAS STOPPED AT A STOPLIGHT IN MARYSVILLE, OHIO. IT APPEARED THAT TRAFFIC STARTED TO MOVE, SO I TOOK MY FOOT OFF THE BRAKE. ALMOST IMMEDIATELY THE EMERGENCY BRAKING FEATURE ENGAGED. WHILE THIS TENDS TO STARTLE YOU BECAUSE IT IS SO ABRUPT, ALMOST LIKE A HEAD-ON COLLISION, I PRESSED ON THE BRAKE. THE BRAKE DID NOT STOP THE CAR. IT WAS SIMILAR TO WHEN ANTI-LOCK BRAKING IS ENGAGED. THE BRAKES FELT LIKE THEY WERE PULSATING, SO THE CAR CONTINUED TO MOVE FORWARD UNTIL IT PRESSED UP AGAINST THE CAR IN FRONT OF ME. I HAVE HAD SOME INSTANCES WHERE WHEN BACKING UP, IN A COMPLETELY EMPTY PARKING LOT OR STREET AND THE CAR WILL BRAKE ON ITS OWN. THERE ARE NO POSTS, TREES OR ANY OBJECTS LIKE THAT ANYWHERE NEARBY TO TRIGGER THE BRAKING. THE MARYSVILLE (OHIO) POLICE DEPARTMENT RESPONDED TO THE ACCIDENT. THE FILE NUMBER FOR THE POLICE REPORT IS 20.01993. I WAS NOT CITED BECAUSE I WAS IN ESSENCE UNABLE TO STOP THE CAR. THERE WAS PLENTY OF TIME TO STOP THE CAR AS I DON'T BELIEVE I PRESSED THE ACCELERATOR AT ALL. THE CAR CURRENTLY HAS A WARNING APPEARING THAT INDICATES DRIVER ASSIST SYSTEM NEEDS SERVICE. I'M NOT SURE IT'S SAFE TO OPERATE THIS VEHICLE SINCE THIS HAPPENED WHILE IN TRAFFIC.
