Last Wednesday Morning June 06, 2023 I started vehicle up to move it closer to my apartment. Once I shifted into "Drive", immediately the engine revved up and vehicle accelerated in high rate of speed across the parking lot, I was applying the brakes, but they were not stopping the vehicle, it then slammed into wooded area and crashed head first into creek beyond the wooded area. I was dazed and bleeding from cut beneath my nose, I climbed out of vehicle and back up the incline the vehicle crashed downward into. Baltimore County Police responded and I explained to Officer what had happened. He advised me to contact my Insurance Carrier and wrote the Incident Report #. During the time while awaiting my vehicle's retrieval from the wooded area, I then photographed and video recorded the damages once retrieved. The air bags did not deploy when the vehicle crashed yet the complete front grill and hood of the vehicle was smashed in, front tire blown.

I purchased a vehicle from auto world usa in bedford, Ohio. I have experienced issued with the car from the day I took the car to try and get inspected in the state of Pennsylvania. I was told that the brakes and tires were good to pass inspection; however when I took the car to get inspected I had to replace all 4 tires, brakes and rotors. I took the car to Mercedes Benz to get looked at due to the burning smell that keeps coming through the vents when the heat is on. I was told the my oil separator was leaking' that my air springs are leaking and that my rear air suspensions were bad. When I purchased the car I was offered a warranty that I was told would cover those types of repairs. Well it turns out the suspension is not covered under the warranty and I cannot get the oil separator fixed because there is a deductible (that I was not made aware of.) I have to take my car to auto world usa in Ohio to get repairs done and I live in pittsburgh, pa. I was told by the warranty company that the dealership could call and they would waive the deductible. Terry dobbins at auto world, was very rude and said that she would not call the warranty after she kept expressing she was going home she just happened to answer my call. What type of company treats a customer like that? I was given falsified information on many levels and was treat like I committed a crime. Auto world usa should be investigated their sales practices are fraudulent. They have put the life of me and my children in jeopardy by selling me a car that had safety issues and it is their due diligence to make sure that the car did not have safety issues before it was sold to a consumer with an "as-is" warranty or not. Me and my kids could be seriously injured because I was sold a car with a safety hazard. Somebody else may not be fortunate enough to find out what's wrong with their car before it's to late.
