“HAD SERVICE ENGINE LIGHT COMING ON PERIODICALLY AND WAS LOOSING COOLANT, BUT COULD NOT FIND ANY LEAKS, WAS TOLD IT WAS PROBABLY FAULTY LIGHT, OR LEAK IN TANK.

Exterior lighting

“I was driving at night switched headlights to high beams - few minutes later switched back to low beams and ALL LIGHTS dash and head lights went completely out . Tried to pull head light knob and nothing - pitch black . Luckily i was a short distance from my home. This is EXTREMELY DANGEROUS ! I have found 33 complaints (so far) about this same problem. This definitely should qualify and be recalled . PLEASE take IMMEDIATE action . Thank you.”

Service brakes, hydraulic

15 reports
“THIS LATEST SERIES OF INCIDENTS OCCURRED WHILE BRAKING HARD. THE ANTI LOCK BRAKING SYSTEM FAILED WITH A GRINDING SOUND OCCURRING. THE "ANTI LOCK" BRAKE LIGHT GOES ON, THE "TRAC OFF" LIGHT GOES ON AND THE "SERVICE VEHICLE SOON" LIGHT GOES ON. SINCE THIS INCIDENT, BOTH WHILE BRAKING AND WHEN I'M NOT BRAKING I WILL HEAR THE GRINDING SOUND AND THEN THE LIGHTS MIGHT GO ON AND STAY ON TILL THE CAR IS SHUT OFF. THIS PROBLEM HAS BEEN GOING ON FOR ABOUT 2 WEEKS AND HAPPENS ON MOST OF MY DRIVING TRIPS. ABOUT A YEAR AGO THE SAME PROBLEM OCCURRED AND IT TOOK TILL MAY TO DETERMINE THAT IT WAS A FAULTY WIRE HARNESS ON THE LEFT SIDE OF THE CAR. I ONLY FOUND THIS SOLUTION BY GOING ON THE INTERNET. THE DIFFERENCE BETWEEN THE TWO SETS OF INSTANCES IS THAT TURNING LEFT AND SLOWING DOWN TRIGGERED THE ISSUE FROM A YEAR AGO WHILE THERE SEEMS TO BE NO TRIGGER FOR THE CURRENT SERIES OF ANTI LOCK FAILURES. IT SEEMS THAT MANY INDIVIDUALS HAVE HAD THIS PROBLEM AND WHEN IT KICKS IN WHILE BRAKING IT TAKES LONGER TO STOP THE CAR. I WOULD THINK THAT THIS IS A SAFETY HAZARD AND SHOULD REQUIRE A FULL INVESTIGATION BEFORE SOMEBODY GETS HURT.”

Steering

12 reports1 crash1 related recall
“UNKNOWN; The issues started around 6 months ago. Just casually driving like usual, and my steering wheel would lock up and be ridiculously hard to turn, which is scary because its happened while turning through lights and intersections and trying to even just park my car. And on some of those occations the trac and abs sensors would come on, but not all the time.”
