CAR WAS ACQUIRED IN FEBRUARY AND SCRAPING NOISE IN FRONT BRAKES WAS NOTICED IN MAY. WAITED TO SEE IF THE NOISE WOULD GO AWAY BY ITSELF BUT BECAME LOUDER AND TOOK TO CADILLAC DEALER, MILLER CADILLAC IN ELLICOTT CITY MD TELEPHONE 410-750-1100 ON JULY 30. I WAS TOLD THE MECHANIC COULD HEAR THE NOISE BUT COULD NOT IDENTIFY THE SOURCE. HE CALLED GM AND THEY TOLD HIM THERE WAS TECH BULLETIN #PIC6290C INSTRUCTING THE MECHANIC TO TELL CUSTOMER THE NOISE IS NORMAL DOES NOT AFFECT SAFETY OR RELIABILITY OF THE CAR BUT WOULD NOT TELL THE MECHANIC THE CAUSE OF THE NOISE, WHICH IS GETTING WORSE! HOWEVER THE TECH BULLETIN STATES THE CAUSE WAS DETECTED AND CORRECTED ON OCTOBER 30, 2017! THE ISSUE OBVIOUSLY IS NOT CORRECTED AND IS NOT GOING AWAY. I AM CONCERNED THE CAR IS NOT SAFE TO DRIVE ESPECIALLY SINCE GM WOULD NOT TELL THE TECHNICIAN THE CAUSE SO I CAN MONITOR IT. THE BRAKE NOISE OCCURS ON ALL ROADWAYS WHETHER FAST OR SLOW WHETHER TURNING OR STRAIGHT AS CONFIRMED BY THE LOCAL MECHANIC. WHY WON'T GM INFORM OWNERS AND MECHANIC SO THEY CAN ASSESS THE PROBLEM AND UNDERTSAND THE DRIVING RISK?
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.
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.
