NHTSA Complaint #10908590 — 2008 BUICK ENCLAVE

I HAVE FINANCED THIS 2008 BUICK ENCLAVE, WHICH I GOT IN FEBRUARY 2016. LOVE THE CAR AND ALL THE SPACE IT HAS. THAT WAS UNTIL TODAY! THIS WEEK AS I WAS LEAVING THE CAR WOULDN'T SHIFT INTO REVERSE. ONCE I GOT IT INTO NEUTRAL I WAS ABLE TO BACK DOWN THE INCLINE FROM THE CARPORT TO THE STREET. IT DID SHIFT INTO DRIVE, BUT WOULD ONLY GO ABOUT 25 MPH ON A BUSY HIGHWAY AND STAYED IN FIRST THE WHOLE TIME. I CONTACTED THE LOCAL CHEVY/GM DEALER AND HE SAID TO BRING IT IN. I COULDN'T BECAUSE I WAS AT WORK. THIS MORNING THE DEALER CALLED AGAIN AFTER BEING ASKED TO BY MY HUSBAND AND SENT A TECHNICIAN TO MY HOME. THE TECH CHECKED IT AND WROTE SOME CODES DOWN AND WENT BACK TO THE DEALERSHIP. THE DEALER THEN CALLED AND SAID IF I COULD GET THE CAR TO HIM HE WOULD HAVE THE TECH CHECK THE FUSES AND RELAYS. HE CHECKED THE CODES HE HAD PULLED AND CHECKED ALL FUSES AND RELAYS AND SAID THAT I NEEDED TO CONTACT A TRANSMISSION SHOP BECAUSE THE COMPUTER WAS NOT TALKING TO THE TRANSMISSION. ALL OF THIS AFTER AN ALMOST HOUR TRIP TO DRIVE 8 MILES TO THE DEALERSHIP AND DRIVE THAT SAME 8 MILES BACK HOME BECAUSE WE KEPT HAVING TO STOP ON THE SIDE OF THE ROAD AND STOP THE ENGINE AND THEN RESTART IT AGAIN ON THAT SAME BUSY HIGHWAY. WE HAD SEVERAL NEAR MISSES (PEOPLE DRIVING THE 65 MILE SPEED LIMIT NEARLY REAR ENDING US). SURELY THERE IS SOMETHING THAT CAN BE DONE TO MAKE SURE THIS DOESN'T HAPPEN TO ANYONE ELSE!
