Filed Apr 24, 2019 · Electrical, Steering · FL

On 7/30/18 I was stranded in the middle of the street after the coolant malfunction light came on. The car began overheating, and there was no AC. I waited for roadside assistance more than 3 hours. I was informed of the incorrect positioning of the alternator from manufacturing, which resulted in multiple lights on cluster. They found the engine belt fell off & replaced the v-belt. They performed li13.22-p-060187, and released stress of alternator and corrected torque. They also worked on a campaign/recall (#2018070005) I had not been informed of. On 3/15/19 during the scheduled 20k service, they tested battery test code with cabin filters wipers and brake fluid service and performed a vehicle inspection. On 3/19/19, 4 days after the scheduled 20k service, I was stranded in the middle of us1 during rush hour traffic on my way to work. The coolant light came again. Thankfully, I safely avoided an accident after the car turned off in the middle of the street. The report showed a weak crank & battery message on the cluster display. They tested the battery and found code hr250bt-dad4lfb stating, 'replace battery'. They removed a0019820208 date 45/16 and installed a0019829108 date 03/18. The drive belt had come off the drive system & found li13.22-p-060187, which stated they needed to perform an alignment procedure of the alternator and installed a new belt for the 2nd time. The belt actually caused damage to the tensioning device, which resulted in them replacing the tensioner, and performing the instruction for li. They test drove the car & said it was fixed. On 4/4/19, just 3 days after picking up my car, it turned off on my again in the middle of us1. The battery light came on and a message popped up stating that the system would shut down in 3 minutes. I was lucky enough to avoid an accident on a congested road.

When idling at the light. The car would shut itself off. All the warning lights will come on. I then have to restart the car with the push start to reset it. Then it'll work fine. I have been to mercedes dealership in new rochelle for four times about this issue. They changed the battery the first time. Two days later the situation occurred again. Then the second and third time they gave me back the car and said they didn't see anything wrong because no codes popped up. Both times I took the car back and the situation occurred again. This problem has occurred over 30 times since over 29,000 miles. The dealership is trying to figure out the issue and right now I am in a loaner vehicle on the fourth time that I have given my car in for service because of this situation. The incident is dangerous in that one time I was in an intersection and it shut off on me. Cars going the opposite way almost hit me because of my reaction time to put the car on start and then restart the car. This can be potentially dangerous for possible accidents. In addition, I have looked online and similar problems have occurred with older models and other models.
