Alternator/generator/regulator Problems of Mercedes Benz C300

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.

Common and known issue with m benz C300 eis/els/steering column. Car engine just dies and will not start due to electrical component malfunction. An expensive, possibly dangerous problem that has not been recognized by mercedes-benz it appears from the other comments on this forum and others. My 2009 C300 was running fine. I maintain regular service. Stopped to grab lunch. Fortunately, I was not in motion or in a dangerous area or in the middle of night in the middle of nowhere. The car would not re-start, yet the lights, radio, panel all appeared to be working, although "remove key from ignition" message appeared. Thought it could be a battery or alternator issue. Had to have car towed to 2 different places, the last of which was the mbenz dealership over an hour away. This occurred at 80k miles on odometer. A major safety and possibly dangerous situation. I thought the mb brand was about reliability, quality, safety. So disappointed. Manufacturer's defective product.

On July 21,2016 at 9am and I parked my car and went to work, 2 hours later came back and try to start the car, did not start. Car door locks and trunk locks open and close but when I turn the ignition on , no response, no display on instrument panel around speedometer gauges. No hissing or cranking or beeping noise also. Steering column was also locked up and inoperable. About 2 years ago command screen with lcd display that controls all functions smoked a little and was shut down display. Going to the last weeks problem steering column has locked me out and also eis that is the communicator from ignition switch and alternator or started do not function also. I happened to see more than hundreds of car with the same year group and model has smiliar problems . My car mileage was 93121. I would like make this as a manufacturing problem of unreliability of the parts and the manufacturer let it roll off assembly line with out doing diligent testing of the parts involved from the suppliers for reliablity and durability and in turn cost the consumers $2000-3000 of unnecessary expense/troubleshoot and fix/ than you very much for your help.

Car stopped suddenly in the middle of the road , lost power, stopped, all the lights went off, pulled it to the side, found out from the dealer alternator gone bad, waiting for new one for instalation at the dealer, surprising to see a alternator on mercedes gone wrong in 30000 miles.
