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.

I purchased my 2020 Mercedes-Benz CLS 450 with approximately 12,000 miles on 08/16/2022. Throughout the course of my ownership the vehicle has had multiple sets of tires replaced due to them either being prematurely bald, developing multiple bubbles, or shredding due to cracked rims. Along with the tires being constantly replaced, I have had to replace 8 rims that have cracked under normal driving conditions. Upon doing research into why my rims crack so frequently, I discovered that this is a common occurrence with my model of Mercedes, as well as several other models. The online forums state, “This is not as a result of your driving, potholes, etc. but due to a design defect with some Mercedes vehicle.
