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.

Official recalls

25V148000 · Power Train:automatic Transmission

Mar 6, 2025

General Motors LLC (GM) is recalling certain 2019-2020 Cadillac CT6, 2020-2021 CT4, CT5, and 2020-2022 Chevrolet Camaro vehicles equipped with a 10-speed transmission. The transmission may become damaged internally and cause the wheels to lock-up.

Consequence & remedy

Consequence: Wheel lock-up while driving increases the risk of a crash.

Remedy: Dealers will install transmission control module monitoring software, free of charge. Owner notification letters were mailed April 7, 2025. Owners may contact Cadillac customer service at 1-800-333-4223 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N242480630.

19V731000 · Tires:pressure Monitoring And Regulating Systems

Oct 15, 2019

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 & remedy

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.
