Filed Nov 5, 2025 · Brakes · PA

Purchased vehicle 6-23 from MB West Chester pa. Feb 3-24 I was parked in a lot once I tried to enter the car I was locked out of the vehicle completely 2270 miles on it. I tried to use the key no avail. I had to contact Mercedes to have my car towed to the shop. Once arrived the damage signal came on. I was told taking the car off the tow truck sometimes makes that signal come on. I never understood. Rep stated it was the battery that died. Which the tow truck guy stated it had to be electrical. Then I returned the vehicle due to loud noise from the front of my vehicle rep stated he didn’t hear it. Then I had to return the vehicle due to brakes squealing very loud. At 5000-7900 miles I was told I needed brakes all around my vehicle. No warranty was applied I paid cash. Left the shop and the noise from the front continued and the squealing from the brakes was still very loud. I brought it back to the shop for treatment care. The rep stated it was a leaf in the front of my engine and he put some special oil on the brakes to stop the squealing but to no avail. The noise continued in both places. I brought the car back for my second treatment and then I was told they hear the noise in the front. They kept the car for a couple of days called me and stated the head dash board was burnt out. The same complaint I was making light flashing and noise. I went to pick the vehicle up stated my warranty had to cover almost $11,000 worth of work. I was devastated, depressed and then I asked is the car safe for me to drive the rep said yes. I was afraid but I had to take my car and leave. I left with tears in my eyes. I could not believe I saved my last of savings to buy me a reliable, dependable Luxury car due to my severe medical issues to make me feel better. I am very disappointed, confused, devastated and very saddened about my brand new vehicle I purchased for myself. I contacted the Attorney General back in Feb 24 and I contacted the lemon Law for support.
