2006 Buick Rendezvous

ENGINE WOULD SHUT OFF WHILE DRIVING OR NOT START AFTER DRIVING. ENGINE POWER REDUCED LIGHT COMES ON AND SPEED THROTTLED DOWN TO 20MPH, CHECK ENGINE LIGHT STAYS ON NOW. REPLACED RELAY BOX UNDER HOOD SINCE A CONNECTOR WAS FOUND BURNED. HAVE ALSO REPLACED THE COMPUTER, ALTERNATOR, IGNITION RELAY SWITCH, FUEL SENSOR RELAY. HAS NOT BEEN DRIVEN ON HIGHWAY AT ALL FOR FEAR OF IT HAPPINING IN HIGH SPEED TRAFFIC. PROBLEMS HAVE BEEN CONSISTENTLY HAPPENING SINCE PURCHASED OCT 2015.

I'VE HAD SO MANY PROBLEMS WITH THIS VEHICLE. SPENT OVER $4000 IN REPAIRS IN THE LAST 6 MONTHS. THE FIRST PROBLEM I HAD WAS WHILE DRIVING ON THE HIGHWAY THE REDUCED ENGINE POWER LIGHT AND TRACTION SYSTEM LIGHT WOULD COME ON AND THE VEHICLE WOULD JUST DECELERATE AND WOULDN'T GO OVER 15MPH. I HAD IT REPAIRED ONCE AND WAS TOLD IT WAS THE WIRING HARNESS AND THEN 2 MONTHS LATER THE SAME THING HAPPENED AGAIN HAD IT REPAIRED AND WAS TOLD IT WAS THE WIRING HARNESS AND COMPUTER THAT NEEDED REPLACED. AND NOW I'M HAVING A SIMILAR ISSUE BUT THIS TIME THE SERVICE ENGINE SOON LIGHT IS FLASHING BUT THE CAR DOESN'T WANT TO ACCELERATE AND TAKES SEVERAL SECONDS TO EVEN GET UP TO 35 MPH. I HAD THIS REPAIRED ONCE AND WAS TOLD IT WAS A WIRING/FUSE ISSUE AND THAT THE CAR WAS ONLY RUNNING ON 3 CYLINDERS AND LITERALLY 2 DAYS AFTER THE REPAIR IT STARTED HAPPENING AGAIN. THIS IS RIDICULOUS. MY MECHANIC EVEN TOLD ME I SHOULD JUST GET RID OF THE VEHICLE BECAUSE IT OBVIOUSLY HAS MAJOR WIRING ISSUES. IT ONLY HAS 130,000 MILES.
