I was driving my car at 45 mph and suddenly, unexpectedly a red light flashed ABC do not drive. Smoke was coming from under the car and the front end of the vehicle collapsed downwardly. I had to call for a tow truck to take my vehicle to the MB dealership. I'm I am waiting for the prognosis. I've had numerous issues with the All Body Control system. Expensive repairs in the $3000-$8000 range. This is a safety issue the breakdown happens abruptly and I was fortunate other cars weren't on the parkway with me. Otherwise a crash could gave occurred.

It has been nearly two years I have stopped driving my 2003 Mercedes SL500, although I only have about 80,000 miles on the car. This is due to ABC warning light(red display: please drive carefully)comes on intermittently and the car drives very bouncy and it feels the car has no shocks, definitely feeling it would be unsafe to drive. The diagnostic message comes up saying "visit workshop". This is the third time this ABC pump issue is stopping me from driving the car, since it first appeared when I had 29,000 miles on the car which was under manufacturer warranty (50,000 miles or four years) and the dealership replaced the ABC pump and also replaced the engine mounts. The ABC red light appeared again when I had about 51,000 miles on the car. It happened also the engine mounts were in need of replacement again. As the Warranty was only for 50,000 miles, Mercedes refused to repair the ABC pump and the engine mounts under warranty and finally I agreed to a 50% cost to me to have repairs done. I expressed my opinion that the ABC pump and the engine mounts had engineering and manufacturing defect and they should have 50,000 miles warranty as the original warranty, from the time of replacement. Regrettably, same ABC malfunction and engine mounts became an issue at 78,000 miles and now the dealer and Mercedes refuse to replace the ABC pump and engine mounts under warranty and have given an estimate of $7336.36 for the necessary replacement of parts, including labor, but excluding taxes. To divert attention from ABC pump, the dealer is now referring to the problem as "power Steering pump"I have extensively researched the issues and it appears the mentioned problems with my car are prevailing issues with other Mercedes 2003 SL 500, and there are 100's of owners who feel Mercedes is not taking responsibility for replacement and repair of these defective parts under warranty. My car is unsafe to drive. There should be a recall by Mercedes to fix these dangerous to drive cars.

My car is a 2003 Mercedes Benz SL500. The abc light keeps coming on and the cars suspension continues to raise and fall. Many times one side higher than the other and not evenly. In 2013 I had a similar problem and ended up costing roughly $3200. Obviously, this is an unsafe mechanical issue. After reviewing you site for recalls on mb 2003 SL500, it appears there was a recall for this problem on my model year and car. After speaking to mb of sarasota and mbusa it was VIN# specific and my VIN wasnt included. I am very confused how this doesnt cover my vehicle. NHTSA caampaign number : 08V405000. Obviously, this should not be VIN specific as my car has this problem for the second time and very expensive to correct. It is a dangerous mechanical defect that mb should take care of. Any help would be appreciated.

Mercedes Benz 2003 sl 500. In 2011 with 34,000 miles on engine, while driving on highway heard loud noise had to pull over quickly because front of car dropped rubbing on tires which resulted in one blown out tire and had car towed to nearest dealership, thank god cuz innocent people or myself could have been hurt seriously, this was a $5,000 job. 2014 with 45,000 miles on engine while driving on highway I heard again that distinctive loud sound which resulted in left side of car dropped rubbing on tires, fender and tire was damaged had car towed to nearest mb dealership. Hydraulic fluid problems has plague this quality series car. This unfortunate event cost me $9,800 because I also had to repair the roof as it is a convertible and hydraulics plays an important role in the operations of the roof. 2018 with 60,000 miles on engine, while driving in the city, I heard loud thud under car I quickly swerve off road to safe spot cuz I knew there was a problem again, the right side of car dropped with fluid spraying out, car then started resting on front and rear tires with hydraulic fluid sprayed every where, had this problem fixed cost was $2,000. Few months after the same problem occurred again. This car that I love so much has been sitting in my garage because car cant be driven and the front end / body of car is resting on both tires left and right side. I am mentally and physically drained and also my pockets. Mercedes Benz Corp. Is fully aware of this problem because of thousands of complaints from owners just like myself. As a multi million dollar company they should have taken the responsibility of a recall in good faith to assist us, after all they would not be where they are today without us customers. Mercedes Benz Corp. Willfully and intentionally is keeping a blind eye to this big problem while we the customers are being taken advantage off

  • 116,578 miles
I own a 2003 Mercedes Benz sl 500 and replaced the hydraulic pump in 2014 for $6400. The car would drop low (on one side if parked for a few hours). Today, January 5, 2017 - the identical problem happened again. While driving, I heard a loud bursting sound and then hydraulic fluid began seeping out also, the abc red dash light illuminated stating that the car is "too low to drive". I managed to slowly drive home (without power steering). This is a huge defect in Mercedes Benz technology and manufacturing - a class action lawsuit is absolutely necessary. This vehicle is defective and dangerous to operate. Also, consumers should not spend thousands upon thousands of dollars on defective parts. By the way, this vehicle has always been serviced by Mercedes Benz dealership technicians. I would appreciate any additional information or support from the NHTSA as I pursue viable recourse options. Thank you!

Suspension drops overnight and has dropped while in motion on the expressway. Red warning to limit speed constantly comes on especially if low on fluid and on bumps. The dealer cannot isolate the cause of pressure or excessive hydraulic fluid leaks. Front bumper damaged as a result. Over $8000 spent and problem not resolved. No confidence in the car unless the supply of fluid is carried in the car at all times. Dealer wanted $16,000 to diagnose and possibly repair but offered no warranty for work.
