Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Nov 1, 2005
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

I OWN A 2003 MERCEDES SLK 230 , WHICH BRAKES ON IT'S OWN AT ALL DIFFERENT SPEEDS . AFTER THE CAR BRAKES TO THE RIGHT FOR A COUPLE OF SECOND THE BAS/ESP LIGHT COMES ON . I HAVE HAD THIS HAPPEN ON THE HIGHWAY AT 60 MPH (VERY SCARY). I HAVE SINCE HAD THE BRAKE SWITCH CHANGED , AND WHEEL SENSORS AND NEW BATTERY. I HAVE SINCE PICKED MY CAR UP AND NO PROBLEM FOR THE LAST 100 MILES UNTIL TODAY WHEN THE SAME THING OCCURRED AT A LOWER SPEED . CAR IS BACK IN THE SHOP READING NO CODES !!!!!! I HAVE GONE TO THE MERCEDES FORUM AND I FIND THAT THIS PROBLEM IS NOT UNCOMMON . IT SEEMS THAT THE YAW SENSOR AND OR LATERAL CONTROL SENSOR GOES AND CAUSE THE CAR TO THINK IT IS SLIDING AND RANDOMLY BRAKES (ALWAYS TO THE RIGHT) . ALL OF THE COMPLAINTS HAVE HAD THEIR OWNERS IN A PANIC . THIS SEEMS TO BE EXTREMELY DANGEROUS . *TR

THE INSIDE REAR VIEW MIRROR IN MY 2003 MERCEDES-BENZ SLK 230 (R170 MODEL) IS AN ELECTRO CHROMIC SELF-DIMMING MIRROR THAT HAS NO MANUAL BACKUP. THE MIRROR CONTAINED A FLUID WHICH LEAKED OUT CAUSING THE SELF-DIMMING MIRROR TO FAIL TO PROVIDE DIMMING AGAINST REAR APPROACHING HEADLIGHTS RESULTING IN THE DRIVER TO EITHER BE BLINDED OR TO HAVE TO TURN THE MIRROR AWAY WHICH GREATLY ELIMINATES REAR VIEW CAPABILITY IN THE INTERIOR. THERE ARE NUMEROUS DOCUMENTED CASES OF THESE MIRRORS FAILING IN VARIOUS MAKES AND MODELS AS A RESULT OF USUALLY FROM THE INTERNAL FLUID LEAKING. I CONTACTED THE OEM MIRROR MAKER, AND THEY REFUSED TO RETURN OUR PHONE CALL/MESSAGES. I RECENTLY READ ON THE MAINTENANCE BLOGS THAT MAGNA DONNELLY WERE REPLACING BUT, STOPPED ALL OF SUDDEN. I HAVE NEVER HAD A VEHICLE THAT HAS EVER EXPERIENCED SUCH A PROBLEM WITH THE REAR VIEW MIRROR. *TR

THE INTERIOR REARVIEW MIRROR IN A 2003 MERCEDES BENZ SLK230 (R170) HAD A FLUID LEAK. THE MIRROR IS SUPPOSED TO BE A CHROMATIC AUTO-DIMMING DEVICE. DUE TO THE FLUID LEAK ALL OF THE DARKENING AGENT HAS MIGRATED TO THE CENTER OF THE MIRROR. THE MIRROR NO LONGER AUTO DIMS, IT CREATES MULTIPLE OBJECTS DUE TO GLARE AND INTERNAL REFLECTION. IT IS COMPLETELY UNUSABLE IN IT'S CURRENT CONDITION. THE MANUFACTURER OF THIS MIRROR MAGNA DONNELLEY USED TO OFFER FREE REPLACEMENT OF THESE DEVICES, WHICH HAVE A LONG TRACK RECORD OF FAILING, BUT NOW NO LONGER DO. THE REPLACEMENT COST OF THE DEVICE IS APPROX. $200 WITH A $100 INSTALL CHARGE BY THE DEALER. *TR
