“Takata recall I just bought a 2000 mercedes ml 320. My AC stopped working and took it to a mercedes certified mechanic. Told me it was a pressure sensor. He then called me back and told me that the wiring harness had fallen apart and all wires were touching each other making shorts thru out the car. He told me that the shorts had fried my computer and the only way to fix all this was to replace the wiring harness. At almost $2000.00 for the repair it seems that mercedes intentionally did this to make money. …”

NHTSA complaint #11111058, filed 2018-07, 169,780 miles

“My 2000 ml with 47k miles suddenly locked on the brakes. The esp light had been showing on very rare occasions for 2 months. I had three instances of sudden lock-up of one or more tires before the dealer found that the yaw sensor had failed. All instances were at low cruise 30-40 MPH with perfect conditions without the esp light showing. Some how I avoided accidents but this is very dangerous. The esp took control of the brakes and applied braking to one or more wheels in an attempt to bring the truck under control. …”

NHTSA complaint #10176935, filed 2006-12, 47,000 miles

“My 2000 ML320 with 53000 miles had suddenly showed check engine light while I was driving it on the highway at ~65 MPH. I exit and as I slowed I could sense the engine was running very rough with shake and strong vibration. Then as I stopped the car at the red light at the exit, the car idled very rough and lots of vibration and then the engine stalled (and shut off). I immediately turned the key to the off position and turned the key back on and the car re-started no problems. The engine idle now only feels slightly rough but idle sound is noticeably slightly louder than before. …”

NHTSA complaint #10137160, filed 2005-09, 53,000 miles

“First incident in august 2012 driving 20-30 MPH just got on hwy and car suddenly slammed on brakes. Could not go over 1000rpm without brakes engaging but fortunately a policeman who witnessed this escorted us to safety on single lane hwy very dangerous. Replaced yaw rate sensor for $1000. Now it is doing the same thing again 2/27/13 and is undrivable. Most likely facing another replacement of yaw rate sensor for another $1000 that only lasted 6 months last time. …”
