Mercedes-Benz SL400

Multiple wheel rims (4) have cracked while driving under normal driving conditions. The last wheel rim crack occurred while on the highway leading to a flat tire upon arriving at destination. The rim was found cracked in two places.

While driving on expressway alert notification displayed that driver side rear tire pressure was low. These are MOE tires so there is no spar tire and should be able to drive at low speed. Car was bought new and had less than 17,000 miles on the tires. Found nearest exit from expressway and drove slowly to nearby service station. Left driver side tire was flat and would not fill with air at service station. Began slowly driving to my home which was about 5 miles away when had to stop again…

MY SL400 SEEMED TO HAVE A SLOW LEAK SINCE I BOUGHT IT, PARTICULARLY ON ONE TIRE. FINALLY WHILE OUT FOR A DRIVE THE TIRE DRAMATICALLY LOST TIRE PRESSURE AND IT LED ME TO GET SERVICE, WHERE I FOUND THAT THE RIM WAS CRACKED. I HAD THE RIM REPLACED FOR OVER USD$1000 IN OCTOBER. THEN IN DECEMBER, SAME SYMPTOM, SLOW LEAK, THEN DRAMATIC LOSS OF PRESSURE. CAR WAS TAKEN TO DEALERSHIP FOR SERVICE AND THEY FOUND THE SAME SYMPTOM, CRACKED RIM, AND INSPECTED THE OTHERS AND FOUND ANOTHER. THREE (3) CRACKED…

I WAS DRIVING A 2006 SL65. THE CAR HAD AN ELECTRONIC BRAKING SYSTEM. THUS, THE BRAKE PEDAL WAS CONNECTED TO A SENSOR WHICH WAS CONNECTED TO A PUMP WHICH TURNED THE BRAKES ON. SOMETHING FAILED. THERE WERE NO BRAKES! LUCKILY I DID NOT CRASH DESPITE BEING ON A CHICAGO CITY STREET. I WAS PROBABLY ON THE ONLY STREET WHERE I WOULD NOT HAVE CRASHED. THERE WAS A PRIOR RECALL ON OLDER SLS FOR THIS PROBLEM THAT WAS SUPPOSEDLY REMEDIED BUT THIS SHOULD BE A NEVER EVENT. THIS SHOULD BE INVESTIGATED. I…

MY WIFE WAS DRIVING ABOUT 1/2 MILE FROM OUR HOUSE WHEN THE BRAKES COMPLETELY FAILED. SHE WAS ON A BACK ROAD AND HAD TO BRAKE FOR A STOP SIGN. SHE WAS ABLE TO PULL OFF ON THE SIDE OF THE ROAD, TO AVOID REAR ENDING A CAR STOPPED AT THE STOP SIGN, AND FINALLY BRING THE CAR TO A STOP. THE BRAKES STARTED TO WORK WITH ABOUT 1 OF PEDAL FROM THE FLOOR. SHE SAID IT WAS SO HARD TO PUSH ON THE PEDAL THAT SHE COULD BARELY DO IT. LUCKILY SHE WAS NOT HURT. HAD THIS HAPPENED ON A MAJOR ROAD OR HIGHWAY …

I WAS DRIVING HOME FROM WORK AND MY ABC LIGHT VISIT WORKSHOP LIGHT CAME ON. OK, THAT'S FINE I'LL TAKE IT TO THE SHOP TOMORROW. WHILE ON MY WAY HOME MY CAR SUDDENLY DROPS IN HEIGHT AND A WARNING SIGN CAME ON SAYING STOP DRIVING, CAR TOO LOW. I PULLED TO THE SIDE OF THE ROAD AND NOTICED THAT MY CAR HAD MAYBE AN INCH OF CLEARANCE IN THE FRONT. THIS IS VERY DANGEROUS BECAUSE IF IT FEEL ANY LOWER I WOULD BE DEAD DURING RUSH HOUR TRAFFIC. I DROVE MY CAR TO THE SHOP AND LEFT IT THERE AND WAITED…

WHILE DRIVING 30MPH, SUDDENLY THE CAR STARTED ROCKING FROM SIDE TO SIDE. I HELD THE STEERING WHEEL FIRMLY, BUT THE CAR STARTED MOVING TO THE RIGHT, SO I STOPPED THE CAR AND TURNED OFF THE ENGINE. IT APPEARED TO BE A SUSPENSION PROBLEM. WHEN I RESTARTED THE CAR, IT WAS OKAY. WITHIN A WEEK OR SO, THE SAME THING HAPPENED, AGAIN. LUCKILY, BOTH TIMES, I WAS DRIVING LOCALLY AT A LOW SPEED, RATHER THAN AT A HIGH SPEED ON THE FREEWAY, WHERE THE SPEED LIMIT IS 65MPH. *JS

A POUNDING NOISE (LIKE A HAMMER HITTING A 2X4) OCCURRED REPEATEDLY WHENEVER I STARTED OR STOPPED. IT TURNED OUT TO BE A FAILURE OF THE BAFFLES INSIDE THE GAS TANK AND REQUIRED A REPLACEMENT OF THE GAS TANK AT A COST OF OVER $2000. THIS IS CLEARLY A DEFECT IN MATERIALS OR WORKMANSHIP AND SHOULD BE THE SUBJECT OF A RECALL. THE BAFFLES SLIDING AROUND THE TANK WOULD ULTIMATELY CAUSE IT TO LEAK IF THE TANK WERE NOT REPLACED. THE DEALER WOULD NOT PAY FOR THE REPLACEMENT. IT HAS APPARENTLY OCCURRED…
