THE INITIAL TIME (3/14) IT OCCURRED, I WAS OUT OF TOWN WITH MY FAMILY, EMBARRASSED TO SAY THE LEAST. HOWEVER, MAINLY UNCOMFORTABLE, TIRED, AND FRUSTRATED BECAUSE MY 87 YEARS OLD DAD WAS STRANDED FOR HOURS AS WELL AS MY 66 YEARS OLD SISTER WHO IS RECOVERING FROM CANCER. THIS PROBLEM WAS A SERIOUS PROBLEM BECAUSE OF OUR LOCATION. WE HAD GONE TO GET DINNER AND ICE CREAM AFTER GETTING ICE CREAM WE BACK IN THE VEHICLE FOR IT WOULD NOT START. I CALLED 911 NO POLICE EVER SHOWED NOR WOULD EVEN STOP TO ASSIST. AFTER 2 1/2 HOURS, WE CONTACTED A CHURCH MEMBER TO FIND OUT ABOUT A MECHANIC IN THE AREA THAT COULD POSSIBLY COME CHECK IT OUT. ANOTHER CHURCH MEMBER CAME TO CHECK IT FIRST, BY NOW 3 HOURS HAVE LAPSED AND THE VEHICLE STARTS. AFTER THIS IT HAS HAPPENED ON THREE (3) SEPARATE OCCASIONS WITH ME (3/19, 3/20, & 3/21) BUT MY MECHANIC SAID IT HAPPENED WITH HIM 3 OR 4 TIMES WHILE HE WAS DRIVING IT TO CHECK IT OUT AND WHILE IT WAS SITTING JUST RUNNING NOT BEING DRIVEN. I WAS ON THE INTERSTATE ONCE, ONCE DRIVING, AND ONCE PARKED AND IT WOULD NOT START. THE TIMES I WAS BY MYSELF ONCE WAS ON THE INTERSTATE, ANOTHER WAS GOING THROUGH AN INTERSECTION, AND ONCE WAS IN A HIGH CRIME AREA WHERE I FELT VERY UNSAFE FOR MY VEHICLE AND MYSELF. MY MECHANIC REPLACED THE CRANKSHAFT AND CAMSHAFT SENSORS AND THE PROBLEM PERSISTS. I HAD A DIAGNOSTIC TEST PERFORMED BUT WAS TOLD THE ITEMS LISTED ON THE TEST 'MAY' BE THE PROBLEM. I HAVE ALSO HAD A PROBLEM WITH IT ACCELERATING WHILE DRIVING AS IF THE GAS IS NOT DISTRIBUTING PROPERLY. IT WAS AS IF IT WAS CHOKING UP AS IF THERE WAS A CLOG. A DANGEROUS PLACE TO BE IN TRAFFIC OR GOING ACROSS A RAILROAD TRACK, WHICH IT HAS OCCURRED SEVERAL TIMES WITH ME. I ACTUALLY WAS ALMOST REAR ENDED ON THE INTERSTATE.

THE VEHICLE WILL ABRUPTLY GO FROM 70 MPH TO 30'S (SEMI-TRAILER CLOSING IN FAST) AND I CAN'T DO A THING ABOUT IT!! SERVICE STABILITRACK HAS BEEN A THORN WHILE UNDER WARRANTY AND PERSISTS TO BE A PROBLEM NOW THAT IT IS OUT OF WARRANTY! FROM EARLY ON, <10,000 MILES AND OVER 10 TIMES SINCE, THIS VEHICLE HAD BEEN IN TO TWO DIFFERENT DEALERS AND THE PROBLEM, THOUGH INTERMITTENT, STILL EXISTS AND IS A HUGE DANGER TO ME AND MY KIDS BUT I CAN'T JUST GO BUY ANOTHER CAR OR TRADE THIS IN LIKE SOME PEOPLE (INCLUDING THE CAR DEALERSHIP MANAGERS) PORTRAY IS THE BEST OPTION WHEN I SHOULD BE ABLE TO GET GM TO FIX THE CAR OR REPLACE IT WHEN THEY CAN'T SEEM TO FIGURE OUT WHY THE PROBLEM PERSISTS. BUT THAT HASN'T BEEN THE ONLY PROBLEM: GEAR BAND BROKE TWICE ON THE TRANSMISSION, HAD TO HAVE TRANSMISSION REBUILT BECAUSE OF FAULTY RADIATOR, AND OTHER ISSUES HOWEVER NONE OF THE PROBLEMS REMOTELY COMPARE TO HAVING TAKEN IT IN FOR SERVICE BECAUSE OF THE REPEATED UNEXPLAINED DE-ACCELERATION AND LOSS OF ABILITY TO MAKE THE CAR DO ANYTHING EXCEPT PULL TO THE SIDE OF THE ROAD AND GIVE IT TEN MINUTES TO STOP HAVING A "TANTRUM" OF SORTS WHILE TRAFFIC WHIZZES BY AND THANKFULLY DIDN'T HIT US (YET). EXTERIOR / AESTHETICS, I LOVE THIS VEHICLE BUT POOR FUNCTION AND EVEN WORSE SERVICE OF PROBLEMS. I'VE REPORTED IT TO CORPORATE BUT THEY DON'T CARE AND DESPITE IT HAVING HAD BEEN INTO THE DEALERSHIP NUMEROUS TIMES PRIOR TO END OF WARRANTY, NOW THEY JUST WANT ME TO START PAYING THEM FOR ALL THESE FIXES THAT HAVEN'T FIXED ANYTHING. ONCE I STARTED PAYING FOR FIXES AND THEN STARTED COMPLAINING THAT THEY AREN'T COVERING WHAT THEY'VE NEVER FIXED; THE MANAGER HAD THE NERVE TO SAY HE'D PAY FOR IT OUT OF HIS OWN POCKET IF HE KNEW IT WOULD FIX IT ... HELLO... WHY SHOULD THE CONSUMER PAY FOR IT WHEN THE PROBLEM IS NEVER REALLY FIXED.
