Fuel & propulsion system
Hello I've taken my vehicle to two Mercedes benz dealerships to get my vehicle fixed for the recall they both said they cannot fix the vehicle it's been going on a month and a half now and this vehicle is my form of income ! And now this issue is messing with my lively hood and this is unacceptable!! They are saying the issue may linger until June July of the summer time. That is unacceptable and i need the issue fixed asap !!!
My car's check engine light came on and my vehicle shut off while I was driving at 40-45 mph on the highway. It has repeatedly done this. I contacted dealership immediately and was told there is a recall for my vehicle coming out on 08/25/2023. My vehicle isn't safe to drive and they did not have a repair available or solution available. I reported problem to dealer on August 5, 2023
