TAKATA RECALL I HAVE HAD TO MAKE MANY REPAIRS ON THIS VEHICLE. HOWEVER, NOW THE LIFTERS IN THE ENGINE COLLAPSED. THE VEHICLE ONLY HAS ABOUT 87,000 MILES ON IT. THIS IS UNACCEPTABLE. THERE HAVE BEEN MANY COMPLAINTS ABOUT THIS VEHICLE AND THE LIFTERS COLLAPSING. WE ARE A ONE INCOME FAMILY AND THE REPAIRS TO THIS VEHICLE ARE ASTRONOMICAL. WELL OVER 3500.00 DOLLARS. THIS VEHICLE IS NOT DRIVABLE AND HAS BEEN SITTING FOR A YEAR NOW AT MY MECHANICS. THE VEHICLE IS OF NO USE TO ME AND HAS BECOME A HUGE PAPER WEIGHT NOW. THE WORST PART IS I STILL OWE ON THE VEHICLE TOO. GM NEEDS TO TAKE RESPONSIBILITY AND DO A RECALL ON THIS VEHICLE FOR THE AFM LIFTERS, OR PAY FOR THE REPAIRS TO THIS VEHICLE. I WILL NEVER BUY ANOTHER GM PRODUCT AGAIN. OWN UP TO YOUR MISTAKES AND TAKE ACCOUNTABILITY FOR THIS PROBLEM. I AM NOT THE ONLY ONE THIS HAS HAPPENED TO. VERY DISAPPOINTED IN THIS VEHICLE THAT IS SUPPOSE TO BE AMERICAN MADE!!!!!!! THEN YOU WANT TO KNOW WHY PEOPLE ARE BUYING MORE FOREIGN MADE CARS. THEY SEEM TO BE MORE RELIABLE THAN THE GM PRODUCTS.

WHILE DRIVING, IN PITCH BLACK DARKNESS ON 6/10/2016 AROUND 1:00 AM, MY HEADLIGHTS SUDDENLY WENT OFF. THE ONLY WAY I COULD OBTAIN LIGHTS WAS USING THE HIGH BEAMS. LOW BEAMS DO NOT WORK AND HIGH BEAM ONLY WORKS IN MANUAL ON/OFF MODE. WE CHECKED THE LAMPS AND FUSES. ALL ARE IN EXCELLENT CONDITION. I HAVE NO LIGHTS WHILE DRIVING OR IN PARK. THE SIDE VIEW MIRRORS MOVE ON THERE OWN AND AT ANY TIME, WHILE DRIVING , IN PARK AND WHEN THE CAR IS NOT RUNNING. THIS HAS BEEN GOING ON SINCE THE DOOR PANEL RECALL WAS REPAIRED. THE DEALER HAS INFORMED ME THAT THERE IS NO RECALL ON THAT EITHER. LAST YEAR (2015) I HAD TO REPLACE THE AIRBAGS (SUSPENSION) ON BOTH REAR WHEELS. THE CAR WOULD DROP DOWN LOWER THAN ANY MID SIZE CAR. ONCE STARTED THE BAGS WOULD INFLATE BUT THE CAR MAY DROP AT ANY GIVE TIME WHILE DRIVING. GM DID NOT COVER THIS COST AND THE DEALER WANTED OVER $1200.00 TO REPAIR. PRIOR TO THAT THE GAS GAUGE QUIT WORKING. WHICH GM DID COVER THE REPAIR COST BUT I NEVER RECEIVED A RECALL. I JUST HAPPENED TO BE AT THE DEALER FOR THE DRIVER DOOR RECALL AND MENTIONED IT.
