The 2020 Mercedes cls has a known defect in their 48V system that turns the engine off in locations with high het zones. I was told by the Mercedes service department this has been occurring in Arizona, New Mexico, Florida, Nevada and saudi arabia. It's a know issue that they are unable to fix currently. I had my children in the car when I was making a left hand turn in a major intersection and the car just stalled on me, leaving me in a panic to try to start the car again before getting into an accident. Mercedes provided me a loaner while they tried to fix my car. I waited 9 weeks to see if they can fix it, but they are not able to. I have contacted the Mercedes dealership as well as the local dealership and told them I no longer want to lease tis vehicle as it is a danger to my family. They would not take the car back nor offer a buyback option. The only option given was a trade in lease, but the options for a car comparable was non existent in the United States as their inventory is extremely limited. I asked again since they had no cars to offer me to get my money back and look for another company. I was told no so I had very little options and took that car back last week. Michael faul the general manager that I have been working with told me in our first meeting that of course they will reimburse me for the 2 months of leases I paid when I didn't have my car. Today I received an email from this Mercedes that has a letter attached to this email that said they will pay back the two month's of leases if I sign this release that they are not liable for any damages or if me or my family get hurt they are not responsible. (I have attached letter for your review) I have tried very much to work with Mercedes corporate in atlanta as well as the local dealership in scottsdale, AZ. I feel this is blackmail and a terrible way of hiding a dangerous car.
