NHTSA Complaint #11390718 — 2015 CADILLAC ESCALADE

WHEN DRIVING THE VEHICLE AND SHIFTING FROM 1-2 THE VEHICLE JERKS VERY HARD. I HAVE TAKEN IT TO THE DEALERSHIP 3 TIMES AND THE DID ALL REQUIRED UPDATES NEEDED. ON THE 3RD VISIT THE DEALERSHIP SAID THIS IS A KNOWN ISSUE AND THERE IS NO REPAIRING IT. THEY SAID GM UPDATED THE TRANSMISSION IN 2019 AND HAVE NOT HAD ISSUES SINCE. WHY WOULD THEY NOT PROVIDE THE UPDATED TRANSMISSION TO ALL PRIOR VEHICLES IF IT REMEDIES THE ISSUE? WHILE DRIVING MY CAR SHIFTS SO HARD SOME TIMES IT THROWS ME FORWARD. THIS OCCURS WHEN ACCELERATING FROM A STOP LIGHT ON THE ROAD OR STOP AND GO TRAFFIC ON THE HIGHWAY. AS FOR THE REVERSE ISSUE, THE CAR WILL ABRUPTLY ENGAGE THE BRAKING SYSTEM MAKING IT SEEM AS OF YOU HIT SOMEONE OR SOMEONE HIT YOU WHILE IN REVERSE. THIS OCCURS MAINLY WHEN REVERSING INTO A PARKING STALL. IT IS HIGHLY DANGEROUS AND CAN CAUSE WHIPLASH TO SOMEONE WHO IS NOT AWARE IT CAN OCCUR.
