A FEW MONTHS AGO I NOTICED THE PASSENGER SEAT WOULD SHAKE WHILE CAR WAS IN MOTION AND ANY SPEED. THEN SUDDENLY THE SEAT STARTED HAVING TROUBLE SLIDING BACK AND FORTH WHEN TRYING TO GAIN ACCESS TO THE REAR SEAT. THEN THE SEAT STOPPED LOCKING IN PLACE AND MY HUSBAND OFTEN COMPLAINED THAT HE WAS FEELING THE SEAT SLIDE BACK AND FORTH. THEN FINALLY, ABOUT 3 WEEKS AGO DURNING A RAIN STORM ON THE WAY TO WORK JUST ABOUT TO MERGE ONTO THE HIGHWAY WHEN TRAFFIC SUDDENLY STOPPED, I WAS UNABLE TO STOP STOPPING TIME AND I HAD A MINOR FENDER BENDER (10MPH OR LESS). THE SMALL IMPACT MADE THE PASSENGER SEAT MOVE ALL THE WAY FORWARD, THE SEATBELT MANAGED TO DIG INTO THE SEAT POSSIBLE STOPPING THE SEAT FROM GOING EVEN FURTHER BUT THEN AGAIN THE SEAT MIGHT HAVE JUST RAN OUT OF TRACK. WHATEVER THE CASE MIGHT HAVE BEEN, I CAN'T IMAGE THE INJURIES THIS MIGHT HAVE CAUSED IF I HAD A PASSENGER SITTING IN THIS SEAT THEY POSSIBLY WOULD HAVE FACE PLANTED ON THE DASHBOARD OR MUCH WORSE. MY CHALLENGER IS CURRENTLY IN THE SHOP FOR A NON FUNCTIONING PASSENGER SEAT I HOPE THEY FIX THE SEAT BECAUSE I HONESTLY DON'T FEEL COMFORTABLE HAVE ANYONE SIT IN THE SEAT.
