2018 BUICK REGAL Power Train Problems

STEERING WHEEL JERKS BACK ON AUTO START AFTER AUTO STOP. EXTREMELY DANGEROUS THE ISSUES HAPPENED WHILE DRIVING AND AT RANDOM. REPORTED THE ISSUE EARLY FEBRUARY 2020 AGAIN IN EARLY MAY 2020 AFTER FAILURE TO DUPLICATE THE ISSUE BY THE SERVICE DEPARTMENT.REPORTED THE ISSUE AGAIN EARLY OCTOBER AFTER THE ISSUE WAS WORSE. ACCORDING TO GM FIELD SPECIALIST THE STEERING RACK WAS THE ISSUE, IT WAS REPLACED BUT THE ISSUE WAS STILL PERSISTENT AND THEY CONTINUED TO HAVE THE VEHICLE FOR ABOUT A MONTH. VEHICLE WAS RETURNED BACK TO ME WITH A SHARPENING NOISE AND A STEERING WHEEL GOING LEFT. HAVE NOT HEARD BACK FOR REPAIRS.

WHILE BEING DRIVEN THE VEHICLES TRANSMISSION FAILS TO SHIFT GEARS WHILE RPMS ARE REGISTERED THE TRANSMISSION FAILS TO RESPOND AND LACKS POWER. I WAS FORCED TO SHIFT MANUALLY TO TRY AND GET THE GEARS TO SHIFT WITH NO LUCK AFTER QUICKLY MAKING THE SWITCH BETWEEN AUTOMATIC TO MANUAL TWICE THE AUTOMATIC TRANSMISSION RESPONDED WITH A LOUD CLANK AS IF THE SEMI BEHIND ME HAD HIT ME AND THE RESPONDED WITH ACCELERATION. THE ISSUE WAS REPORTED FIRST EARLY FEBRUARY 2020 AGAIN IN EARLY MAY 2020 AND RECENTLY EARLY OCTOBER 2020 SERVICE DEPARTMENT FAILS TO DUPLICATE ISSUE. MY DASHCAM CAPTURED VIDEO WHILE BEING DRIVEN BY THE SERVICE DEPARTMENT EXPRESSING THE STRANGE FEELING THE TRANSMISSION WOULD GIVE THEM WITH TORQUE AND SHIFTS.
