CAR JUST LOST POWER WHILE IN STOP AND GO TRAFFIC GOING 10 MILES AN HOUR. HAD TO PUT IN PARK AND RESTART IT, AND CHECK ENGINE LIGHT CAME ON. *TR
MY CAR JUST STOPPED ON ME WHILE DRIVING SO PUT A USED ENGINE IN FROM EBAY AND A COUPLE YEARS LATER THAT ONE DIED ON ME WHILE ON THE HIGHWAY. I BELIEVE THE PISTONS BLEW OUT THE BACK
I CONTINUALLY NOTICED THAT THE AIR VENTS EXPRESS A VERY SMELLY ODOR. WHETHER IT IS THE AIR CONDITIONER OR THE HEATER- MAKES NO DIFFERENCE. WENT TO THE DEALER AND THEY SAID IT WAS THE AIR CONDITIONER RESIDUE AND TO RUN MY FAN ON VENT TO GET RID OF THE MOISTURE BUILDUP. I HAVE DONE THIS FOR A COUPLE WEEKS NOW AND THEY STILL SMELL LIKE MOLD AND MILDEW- I HAVE ONLY HAD THIS CAR FOR 60 DAYS AND CAN'T GET RID OF THE SMELL. I HAVE ALLERGIES AND THIS IS A REAL PROBLEM FOR ME. I HAVE HAD MANY CARS OVER THE YEARS AND NEVER EXPERIENCED THIS EVERY HAPPENING WITH THE AIR CONDITION IN A VEHICLE. HAVE THERE BEEN ANY COMPLAINTS OF THIS PROBLEM?IS THERE WARRANTY COVERAGE FOR THIS OR DO I NEED TO GO BACK TO THE DEALERSHIP AND LODGE A COMPLAINT TO GET RID OF THE CAR? *TR
ABOUT THE COOLING SYSTEM OF THE ENGINE,HOW I CAN FOLLOW UP THE ENGINE TEMP. WITHOUT TEMP.GAUGE THIS BAD DESIGN ,IT SHOULD WAIT UNTIL THE ENGINE CLOSE TO BURNING UNTIL THE ALARM INDICATOR DISPLAYED. SO, WE NEED SOLUTION FROM THE OWNER ABOUT THIS PROBLEM. THANKS, *TR
NO COMPLAINT ABOUT AIRBAG BUT HAD TO PUT AN ENGINE IN TWICE OVER 2 YEARS
