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.

Car is extremely hard to turn/loss of power steering. Noticed that there was a recall on these vehicles but my vin was not included. Mechanic said Power steering rack is bad. This has been an ongoing issue with this car since purchased with only 70,000 miles - not sure why this VIN was not included in the recall? Car stock radio screen also has intermittent issues with displaying properly.

When reviewing the vehicle for purchase I noticed the SRS light on. I brought it to the dealerships attention.

After I brought it back they let me know that they didn't see any SRS lights and would not be servicing the vehicle. There has been multiple mechanical issues with the vehicle including but not limited to the transmission going out, break recalls, engine leaks and now I'm being informed that my passenger air bag is deactivated. I just want a safe vehicle.

SPORADICALLY, WHILE DRIVING ALONG ON LOCAL ROADS OR THE HIGHWAY, THE CAR'S TRANSMISSION DOES NOT SWITCH HIGHER THAN THIRD GEAR. THE PROBLEM OCCURS ABOUT ONCE A MONTH. UPON ENGINE RESTART, VEHICLE DRIVES PROPERLY. MY PEDAL SHIFTERS DO NOT WORK WHEN THIS PROBLEM OCCURS; I CAN TRY TO SHIFT GEARS WITH THE PEDAL SHIFTERS, AND THE SOFTWARE INDICATES A CHANGE FROM 3RD TO 4TH GEAR, BUT THE ACTUAL TRANSMISSION DOES NOT CHANGE GEARS. IT REMAINS STUCK IN THIRD GEAR WHETHER I SPEED UP OR SLOW DOWN. IF I PLACE THE VEHICLE IN PARK AND TRY TO REVERSE, THERE IS NO POWER TO THE VEHICLE UNTIL I RESTART THE CAR. THIS SEEMS TO BE OCCURRING WITH MORE AND MORE FREQUENCY. I HAVE A SAFETY CONCERN THAT I HAVE TO PULL OFF THE ROAD AND RESTART MY CAR WHENEVER THIS OCCURS. THIS SEEMS TO BE PROBLEMATIC FOR SEVERAL OWNERS ON THE NHTSA SITE AND ONLINE. *JB

THE ELECTRONIC AIRMATIC SUSPENSION SYSTEM IS MALFUNCTIONING FOR THE SECOND TIME IN A YEAR! WHEN THIS HAPPENS THE VECHILE IS UNDRIVEABLE BECAUSE THE FRONT END FALLS ON THE FRONT WHEELS. *TR CAN YOU BELEIVE I PAID EXTRA DOLLARS FOR THIS OPTION AND IT APPEARS THAT THIS WILL BE AN ONGOING PROBLEM AND I BELEIVE THE PROBLEM WILL NEVER BE RESOLVED. I CAN SEE MYSELF IN ANOTHER 5000 OR 6000 MILES EXPERIENCING THE SAME PROBLEM! I BELEIVE FROM PAST EXPERIENCE WITH MERCEDES BENZ THE ELECTRONIC AIRMATIC SUSPENION WILL NEVER WORK PROPERLY AND THE CAR SHOULD BE DECLARED A LEMON FOR THE FOLLOWING DOCUMENTED REASON! I OWN A 1963 MERCEDES BENZ 300SE WITH THE OLD MERCEDES BENZ HYDROLIC VERSION OF THE AIRMATIC SUSPENSION AND IT ALWAYS BROKEN. THAT WAS 43 YEARS AGO AND THE CRAFTED THINKERS AT MERCEDES BENZ HAVE NOT RESOLVED THE PROBLEM YET! WHEN I BOUGHT THE VECHILE THE SALESMAN ASSURED ME THAT THEY HAD WORKED OUT ALL THE PROBLEMS WITH THE AIRMATIC SUSPENSION AND I HAD NOTHING TO WORRY ABOUT! IF THAT'S THE CASE! WHY IS MY CAR IN THE GARAGE AND I HAVE NO VECHILE TO DRIVE UNTIL MY SERVICE APPOINMENT THIS WEDNESDAY COMMING UP. MERCEDES BENZ OFFERS A $70,000 TRUCK WITH A NIGHMARE ELECTRONIC SUSPENSION FOR AN OPTION THAT DOES NOT WORK THAT YOU PAID EXTRA MONEY FOR. WHAT A JOKE? I REALLY THINK THEY SHOULD REPLACE THE VECHILE. THIS PROBLEM WILL NEVER BE RESOLVED! ALL I,M GONNA GET FROM MERCEDES BENZ IS WE WILL FIX THE PROBLEM SIR! DON'T WORRY! THE BIG QUESTION WHO WILL PAY THE COST OF THE REPAIR OF THIS PROBLEM WHEN MY WARRANTY ENDS IF I KEEP THIS VECHILE! IT'S NOT FAIR!

THE REAR BRAKE LIGHTS SOCKETS ARE GETTING BURNT CAUSING THE BRAKES LIGHT TO FAIL. CORROSION ON A CONNECTOR CAN CAUSE THE TAIL, BRAKE OR REAR TURN SIGNAL LIGHTS TO DIM OR FAIL. THIS IS A SAFETY ISSUE BECAUSE IT CAN MAKE CARS LESS VISIBLE TO OTHER DRIVERS, WHICH CAN INCREASE THE RISK OF A CRASH. THIS IS THE EXACT SAME ISSUE WITH THE 2008 - 2011 MERCEDES C CLASS WHICH RECENTLY HAD A RECALL ISSUED.
