“WHEN IDLING THE VEHICLE IS IDLING VERY HIGH. ALSO THE CHECK ENGINE LIGHT IS COMING ON, AND WHILE DRIVING THE VEHICLE AS YOU START TO LET OFF THE ACCELERATOR, THE VEHICLE JERKS YOU, ALMOST TO THE POINT OF GETTING WHIPLASH. WE HAVE HAD IN THE SHOP AT LEAST 3-4 TIMES AND LOTS OF TIMES FOR A WEEK AT A TIME. WE WERE TOLD THAT THE CHECK ENGINE LIGHT WAS DUE TO THE GAS CAP, THEY REPLACED THAT, 2 DAYS LATER IT WAS BACK ON. THEY ALSO SAID IT WAS THE FUEL SENSOR, REPLACED THAT AND ITS STILL ACTING AS THOUGH ITS NOT GETTING ENOUGH GAS. AS FAR AS THE JERKING OF THE VEHICLE THEY WONT TELL US WHAT COULD BE CAUSING THAT. ALSO THE MECHANIC STATED THAT THERE WAS NOTHING THAT THEY COULD DO TO RESOLVE THESE PROBLEMS. THIS VEHICLE IS AN ACCIDENT WAITING TO TAKE OTHERS LIVES. *TR”
