Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

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.

I was driving an 03 SL500 and from the start the battery light (white stayed on) replaced both front and back battery and voltage regulator, now the red battery light is on and stays on. On last night, while driving down the highway, I heard a pop, car dropped and warning came on saying car was too low and fluid is leaking from the front driver side look like by the front wheel. Mechanic did a lot of guessing and still not fixed.

Driving along the freeway at 65 mph when the whole front left side drops to within inches off the ground!! Mercedes is well aware of this lemon feature on there vehicle and is some how still allowed to sell them in the us, much less not do a damn thing about the lemons they have sold.

This car has had abc problems from day one. First we had hydraulic leaks, we replaced struts, then the pump went out and had to replace that. Now the car lowers on it's own when ever it feels like it. If I park the car it lowers and when I reverse the low front end will get trapped and drag, now the front bumper is ruined...this will be my last Mercedes.they need to recall this terrible system, .I never have any problem with my Lexus..ijs

Started car and got message: "abc malfunction, car too low". in actuality, car elevated. The ride of the car has changed. It has a soft and floaty feeling compared to its normal stiffer ride. I have seen the above complaint on the internet multiple times. It seems this is a wide problem. I haven't heard any recalls from Mercedes.

Abc active body control system failed resulting in a drop on the driver side. Mercedes mechanic said that this has been a defect and regular issue with 2003 SL500 where there is either a leak in one or more struts or the pump failure; but yet Mercedes is not taking accountability for this defect. After researching this on the internet, it is clear that this has been an issue not only in us but around the world and Mercedes has not addressed this issue because they are making thousands of dollars repairing this defect per vehicle. Please look in to this issue. Just google 2003 Mercedes Benz SL500 abc and you will see for yourself how many individuals have had the abc issue.

My 2003 sl 500 with 22,500 miles is dangerously unsteady and pulls to the right also has a knock in the right rear. I took it to the local dealer and they replaced the fluid in the abc system for $300 +. it did not help. They say that they can begin replacing parts in each wheel at $2000 per wheel and see if it works, but no guarantee. It appears that they don't have a clue. I have contacted Mercedes help line but they just said to take it to the dealer. I bought this car new in 2003 for my wife and expected it to last a long time and she will not drive it anymore. Here I have $100,000 car that is like new inside and out that is not drivable. Mercedes should be ashamed of themselves for not backing up their product. I have had 9 Mercedes starting with a 1962 diesel sedan but I will never, ever buy another and I spread the word to everyone I see interested in buying an expensive car.

Immediately after purchase, noticed a considerable front nose drop while driving issue repeated frequently while driving. Overnight, the vehicle would drop 3-4 inches. Took vehicle to repair shop and watched as vehicle "bucked up and down" as if in a low-rider show. Mechanic stated it was a common occurrence and recommended changing sensors. Vehicle taken to Mercedes dealer with copy of recall notice 08V405000. Dealer replaced left front strut ($1500) instead, stating my vehicle is not part of this recall. Strut replacement eliminated the 3-4 inch overnight drop, but the nose drop during driving was not fixed. Dealer now wants to replace the abc sensors ($1200-$1500). To date, 3 of 4 struts/shocks have been replaced. Car is in an unsafe condition. Numerous posts on internet regarding this issue! please help.

We were driving 65mph on the highway when suddenly our 2003 mb 500sl became erratic with the suspension dropping down on the driver's side. I was forced to quickly pull off the highway. It was a terrifying experience and we were extremely lucky to pull over right away without hitting other cars. The car was very low to the ground on one side. After restarting the car, the suspension improved enough to get us home. On my drive to the dealership the car was very low everywhere forcing me to drive 35mph and it bottomed out on a bump on the highway. The dealership informed us that the abc system pump had failed and the car additionally had leaking rear shocks. Our car has low mileage and very little wear. The dealership quoted $7600 to install a new pump, flush out and replace the hydraulic fluid and install new rear shocks! they stated that this may not completely fix the abc problem as additional damage may have occurred from the failed pump and debris in the system. This is outrageous! there is clearly an ongoing and very prevalent and dangerous defect with the Mercedes Benz abc system, as it is happening to so many vehicles. There must be a recall on these vehicles. This is a very serious problem which could easily result in multiple highway fatalities. Mercedes Benz has to take responsibility for their defective system before someone is killed.

I have had ongoing / continual problems with the 2003 sl 500 model 230 abc (active body control) system. The resulting issues occur at random and with little consistency. The resulting effect causes the car to drive soft on some occasions and rigid on others. The problem has been diagnosed and reported to the local dealership and other opportunities to attempt to repair the issue. Thus far there seems to be no one who can properly affect and improve the situation. I contacted my local mb dealership on June 27, 2011 inquiring regarding a recall reported in the NHTSA recall system. The dealership said this was not a recall however the recall 08V405000 suggests otherwise. The continual problems with the abc systems makes me weary of mb ability to correct safety and driving issues. While this has not resulted in an accident or damage my fear is if mb nor the dealership recognizes there is an issue with abc systems, how many unrepaired and unsafe vehicles do we have on our streets?
