Car worked fine, all the sudden it wouldn't turn over, I would put the key in and turn it and nothing would happen, I was stuck and had to catch a ride, lucky that I was able, a car company that is supposedly reliable shouldn't allow there cars to completely give out on people during the middle of winter storms and not take ownership, when the customer has taken good care of the car. Talked to several mechanics and turned out it was the Electronic Steering Lock (ESL) module that had malfunctioned probably due to the software and electrical. Due to this only the Benz dealerships can repair, I had to tow it to a dealership and was charged around $2000 after haggling over the price. Terrible experience and should be recalled by MB, I have seen many complaints about this online and was very disappointed there wasn't a cheaper solution. Was both a safety issue, inconvenient and very costly.
