“While driving my mercedes benz 2003 SL500 the brakes became disabled without warning. It was a terrifying experience. The first mercedes dealer I phoned told me that there was no known safety recalls for the brakes. The second mercedes dealer that I contacted informed me about 2 recalls in 2004 and 2005. I phoned the mercedes benz USA headquarters and spoke to a case manager who told me that mercedes' responsibility with this safety issue expired in 2012. How can a safety issue such as having no brakes while driving expire? …”

NHTSA complaint #11023809, filed 2017-09, 87,800 miles

“While driving the car in town on city streets the sbs brake system failed as I came to a turn leaving me with no brake response even though the dealer says it was supposed to have hydraulic back-up to stop the car. I was able to coast and stop the car only with the emergency hand brake. The sbs system has been recalled twice by the factory but there is still something very wrong when a modern car had no back-up system. These cars are dangerous! Luckily for me there was no accident and I had the car towed to the dealer and it is being repaired.”

NHTSA complaint #10969321, filed 2017-03, 85,000 miles

“I own a 2003 mercedes benz sl 500 and replaced the hydraulic pump in 2014 for $6400.00. 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. …”

“While driving to work, I was going about 35 MPH when the dash lights up red saying service brakes, stop vehicle, etc . My mechanic looked over everything to do with brakes and could not fix it. He called mercedes of tallahassee and was told it was an electrical issue that was a common problem with this vehicle. It did have a recall on it, but it expired in july last year, just my luck. So I googled it and have now found tons of people with the same experience! How can the vehicle safety administration legally allow mercedes benz to continue letting this happen to people? …”

The contact was however able to pull over and eventually the vehicle came to a complete stop. The vehicle was towed. …”
