When starting the vehicle, the horn intermittently goes off and will not stop. Must turn off the car to get the horn to stop sounding. Then, must turn on the car and turn off the car a few times to make it stop until it all starts happening, randomly, again. Took the vehicle to the Mercedes dealership where car was purchase and has been routinely serviced and they said the problem was a faulty steering wheel switch. The only way to fix the issue is to replace the entire steering wheel itself. The cost for an identical factory wood steering wheel (which is what the car was purchased new with) is $3,000; if we opted for a leather wrapped steering wheel instead the cost would be $1500. The other workaround is to pull the fuse and not have a horn at all. This is a safety issue and should not cost this much to have a steering wheel switch replaced! this is essential, basic equipment, and starting happening on a vehicle with less than 40,000 miles. Have continued to follow-up with dealer to see if there has been a recall or if they will fix, but Mercedes is not taking responsibility for the problem.

I had just started driving down the road 2 miles and going around 25-30 mph and the car shut off and the steering wheel locked. There was cars behind me and I was able to put my hazards on. Thankfully cars were coming up to stop sign so I was able to steer off road. Started car up and drove a little further and car shut down again and locked steering repeated 4 more times til was able to get home. I was getting ready to get on freeway with my young kids in the car could have been so dangerous.

My mb GL450 2007 cars horn started to randomly go off for no reason multiple times. This happened three times, once when I started the car in grocery store parking lot, second time while I was driving and scared other motorist to pull over. Only way I could make it stop was to pull over and turn off the car. When I turned on the car the horn started again, turned off, turned on drove to repair shop. Repair shop told me the spring for the horn had warn out and the electronic console in the steering wheel was shot. Told me you can't order the part anymore because it was discontinued, so, we have to order a whole new steering wheel for $1,200 plus $600 in labor.

The contact owns a 2007 Mercedes Benz GL450. The contact stated that the vehicle failed to start however, all of the warning lights on the instrument panel were illuminated followed by a warning chime. The contact also stated that there was a leak from the bottom of the vehicle. The vehicle was towed to the dealer for diagnostic testing where the technician recommended a fluid flush and replacing the power steering seal, steering column module, wiring harness, auxiliary battery and transmission. In addition, the contact was advised that an oil change was needed. The manufacturer was not made aware of the failure. The vehicle was not repaired. The approximate failure and current mileage was 103,000. Kmj

I had been noticing that the front of my car had been dropping down and rising up spontaneously. When the front of the truck dropped down the car began to violently bounce up and down to the point that I nearly hit my head on the roof. The car was barely drivable until it rose up again. On 2/18/2011 I pulled my truck out of the garage and heard an explosion and the right front side dropped down and would not rise up again. I took it to my mechanic and he said that the air struts were gone. The right side had exploded. He contacted many of his prior employee's who work at Mercedes Benz dealerships and they told him they had been having problems with this part. They even had the parts in stock due to the demand. This is definitely a safety issue and if I or my wife were on the highway traveling at 70 mph and this occurred, that could have been a fatal rollover. I also have a problem with my powersteering locking up when I turn the wheel.. my mechanic also said that this has been an issue and a recurrent problem part. I bought this vehicle for safety and it turns out this is the farthest from it. I also had to have my driver's seat replaced by Mercedes as it burnt a hole through the leather nearly catching my wife's coat on fire. Please investigate.
