Recent owner complaints
- Electrical system
My first complaint is that headlights, low beam, would not work. Only high beams worked. The issue stopped, unexplainable, on its own, has not occurred again. The 2nd complaint is the radio volume would 'slip' as if there were a loose wire to the speakers, and loss of sound became more frequent and for longer periods of time, eventually all sound stopped, it has not been fixed, as of yet. 3rd complaint, a brand new battery, in under a year of use, went completely dead, without any visible explanation. When an attempt to jump start the vehicle the cables from another cars battery were touched at my cars battery, it sparked, indicating to the person performing the task, there is a 'short'…

THE ENGINE LIGHTS COME ON, THEN THE CAR STARTS CHUGGING AND SHUDDERING AND SOUNDS AND FEELS AS IF IT WILL SHUT DOWN. I AM NOT ABLE TO ACCELERATE. THIS IS A SERIOUS SAFETY RISK IN TRAFFIC, ESPECIALLY IF DRIVING ON THE INTERSTATE. THE CAR WILL NOT MOVE AT ANYTHING OVER 20 MPH, IF IT EVEN ACCELERATES AT ALL. I USUALLY END UP COASTING TO THE SIDE OF THE ROAD AND SHUTTING THE ENGINE DOWN. I LET IT SIT AND TURN IT BACK ON AND IT MAY OR MAY NOT LET ME GO AGAIN. *TR
- Exterior lighting
WHILE DRIVING THE LOW BEAM HEADLIGHTS WILL GO OUT. AND NOT COME BACK ON YOU HAVE TO TURN ON HIGH BEAMS TO HAVE HEADLIGHTS STOPPED AND PULLED OVER TURNED OFF THE VEHICLE TURNED IT BACK ON AND LOW BEAMS STILL DID NOT COME BACK ON
- Exterior lighting
THE LOW BEAM HEADLIGHTS KEEP GOING OUT. ALL OTHER LIGHTS STAY ON AND THE HIGH BEAM LIGHTS WORK. ONLY THE LOW BEAM HEADLIGHTS ARE AFFECTED. THIS HAS HAPPENED WHILE IN MOTION AND FROM A STOPPED POSITION WHEN FIRST STARTING THE CAR AND PUTTING IT IN DRIVE. I HAVE RESEARCHED IT ON SEVERAL GROUP WE SIGHTS AND FOUND THAT THE PROBLEM IS THE HEADLIGHT DIMMER MODULE (HDM). I HAVE REPLACED THIS TWO TIMES OVER THE LAST TWO YEARS WHICH ALWAYS FIXES IT FOR ABOUT A YEAR THEN IT STARTS FAILING AGAIN. THIS IS A VERY DANGEROUS SITUATION BECAUSE IT HAPPENS AFTER DARK. I CAN PULL OVER AND STOP, OPEN THE HOOD AND TAKE OFF THE FUSE BOX COVER AND REMOVE THE HDM AND PUT IT BACK IN THE SOCKET. SOMETIMES THIS WORKS…
