NHTSA Complaint #11664002 — 2019 MERCEDES-BENZ C 300

I had a A1 service completed on 5.23.25 with Mercedes Benz dealership in Sourh San Francisco. 2233 Gellert Blvd. On [XXX] 48 hrs later as I was leaving working- 4-5 blocks before entering the freeway, my car suddenly struggled to drive over 20MPH and the check engine light came on. I pulled over a block before entering freeway. I had it towed and got a Lyft’ ride home. It was a holiday weekend and I had to rent a car . Vehicle accessed 2 days later . I was told it needed a software update and there was a bulletin that came out in 2024 recommending to have the update and I needed to pay to have it repaired by performing a hard/soft upgrade . No empathy was evident . I said I knew nothing about it - dealership said they weren’t obligated to advise. I could have been in a collision or caused and accident and seriously injured had it occured while on freeway . This should be a recall as my life was at risk and so are others driving this year, make and model. The Mercedes Rep. told me she tested the car and was surprised by how it struggled to get past 20 mph, she thought maybe the mechanic had made an error a few days before. I feel very lucky I wasn’t in an accident- or a worst seriously injured! This bulletin warning should be a recall and looked into for a future recall that could save life’s. Knowing, this is a risk for a possible accident , it’s unacceptable that it is only a bulletin and not mandatory to share with owners of the this car. This was very scary and stressful situation. I was stuck in an area in Oakland, Ca known for high crime. In the end Mercedes waived the repair fee, they said under the circumstances and how my life was put as risk . I still think perhaps a wire or something may been disconnected- but no one will admit. Hence they waived fee. Please investigate , I look forward to your findings.
