2006 Mercedes Benz CLS500 -Car sometimes does not start. It cranks , but doesn't fully start. Twice already, my car died while driving . I'm here now broken down on the side of the road . But yesterday , people at auto zone did a free diagnostics check. It's the crankshaft sensor. As soon as I get home , I will buy the part , and have it replaced . Hopefully that fixes the problem .
Car turned over and attempted to start but wouldn't budge, you could tell it wasn't a battery issue. This problem won't display any errors, gave a check engine light once. Took it to tires plus and they replaced the crankshaft position sensor within 30 minutes and car was fine $150 out the door.
It suddenly lost power during 68 mph on I-10. All indicators lit up and steering wheel engaged in lock position. The other time, it lost power after running over a bump. After performing a diagnosis and online information, it could be a malfunctioned Crankshaft Position Sensor. Just had it replaced and tested for 30 miles with no problem. Still wait to test another long trip this week.
Same issues as other post.... Had car hooked up for diagnostic test and it came back that The crank shaft sensor was the issue
