What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Vehicle was hit in a frontal collision at 70 mph in which driver's side/ passenger's side air bags did not deploy. However, air bag system indicated that all air bags did inflate or deployed. Please give any further details.
Tl* the contact owns a 2001 mercedes-benz slk230. While driving approximately 75 mph, the esc warning indicator suddenly illuminated and the esc activated. As a result, the front passenger side brake suddenly activated and the vehicle turned to the right. The vehicle was not diagnosed or repaired.
The car engages the brakes on it's own when I'm driving at speeds above 30mph.
More often than not, when I start up my vehicle an indicator for a light out appears on my dash. I have been pulled over several times for a right rear brake light being out. I have replaced the bulb numerous times.
He engine died while I was driving in traffic. I managed to coast to a corner and get off the main street, there was no warning.I had to leave this car for one day to find it towed by police , and had to call and get it the next day payed 300$ and get it towed again to a mecanic payed 85$ and 100$ for checking.
The mercedes benz slk 230 2001 model brakes randomly with the front tires left or right or both, engine performance goes down to super slow for a fraction of a second. The car turns to the left or right and slows down abruptly and only due to my fast reaction I am able to avoid traffic accidents !
My vehicle would would suddenly come to an abrupt stop without applying the brakes. It would do this at any speed. It was happening everyday. We had to stop driving it. We towed it to the dealer and they told us the yaw sensor was bad. There are many complaints about this on the internet.
The mirrors fail losing their ability to provide dimming against rear approaching headlights causing the driver to either be blinded or to have to turn the mirror up and have no rear view capability. I know of many documented cases of these mirrors failing including my own.
