I took my vehicle for service at the Park Place Mercedes dealership on Lemmon Ave in Dallas, TX. Initially I took it to the dealership because my AC wouldn't turn on, was hearing some odd squeaking in the suspension, and because Firestone identified that we had an oil leak at the oil pan. A few days later the dealership called and stated the car was ready for pick up. When I picked up the car the first time, as soon as I drove off of the lot the check engine light came on. I turned right back into the service department and had to leave it there a second time. The dealership analyzed the check engine light and stated that we needed to replace the timing chain. Timing chain was replaced! The dealership called a stated that the car was ready. I went and picked up my vehicle and everything seemed fine.... UNTIL we got home. The next morning I walk up to my vehicle and I see an oil spot. I thought, MAYBE, this spot was from my son's car so I put a cardboard underneath to confirm if the car was leaking. IT WAS. I called the dealership and they sent someone to pick up the vehicle. Dealership contacted later and stated that they found a leak at the Turbo charger outlet tube connection. The seal was replaced and dealership called me to let me know my car was ready. I picked up my vehicle for a 3rd time. All seems good for now. I get to the on ramp for the Dallas North Tollway (less than 2 miles from dealership), I accelerate and the car doesn't accelerate. If anything it bogged down the more I pressed on the gas pedal!!! Oh did I mention I had my family in the car at this time!! The car would not go passed 40 MPH and I am now on the tollway!! I drove the car back to the dealership (VERY SLOWLY) and left it again. Before I left I spoke with the service manager (Mike) and expressed my dissatisfaction with the service at this time. He stated he would make sure it is handled. I get a call from the dealership and they state my car is ready. They state that the seal was incorrectly installed and that the car is good to go. I pick up the vehicle and drive off of the lot. It all seems good when accelerating at lower speeds. Then I pick up speed after a complete stop and I feel a jerk in my car as I get into 2nd gear and sometimes feel it when it hit 3rd gear. I hoped that this issue would self heal so I took it home and drove it for a few days. The jerking never stopped. So guess what??? I took the vehicle back to the service department. This time the dealership recommends an overdue transmission flush! Yeah right!! I am not leaving my car there again. I declined that service. I instead took the vehicle to a 3rd party European shop to get the Transmission flushed. Can you guess the result??? The car still jerks. Mercedes was going to charge me over $500 to flush my transmission for a wild guess to the solution. At the present time my car is STILL jerking!!!! It is very frustrating because I didn't take it in this way. What is more frustrating is that the service department states that they test drove the car every single time. I don't believe that one bit. I found these issues immediately within a mile from the dealership!!! I took the car into the dealership on Dec 19, 2019 and on April 21, 2020 is when I gave up. I have this darn jerk that I am trying to get used to every single day and I have yet to be able to ignore it. I would NOT recommend taking your car there.
On another note our service representative Kortina Chandler provided us the best customer service. If it wasn't for her I would've reacted in a very irate manner as a result of this experience. She did everything she could to keep us happy. Unfortunately we are not happy and very disappointed. We hold Mercedes to a very high standard and they fell very short this time.
