Habberstad BMW

I brought my '07 BMW 328xi coupe for servicing at BMW Habberstad's Huntington NY location in August of 2013 because of sporadic rough idling and engine shaking. Shortly after paying $1418.49 for the services on August 5th, I drove the car off the lot and returned it minutes after due to the same issue. August 8th, I picked my car up after paying an additional $671.22 and drove the car home. Days later the sporadic rough idling and engine shaking continued. I was hesitant to return for servicing because I could not afford additional payments. After months of dealing with the issue, I finally called to see if they would be willing to take another look at the car free of charge. They said I would have to pay an additional $165.00 plus tax! While also calling to get the full value of the monies paid to the company for the services, their representative whom I spoke with, Bill D, was reluctant to give my the information I needed to mtch the value I had listed. I brought my car to the gas station on the corner and had them diagnose the car for $25.00; they pulled a code from my service engine light. P0301 being the code dealing with the problem I have been experiencing which relates directly to the sporadic rough idling and engine shaking. It was easy enough for my to look up YouTube videos on how to fix the car, yet I have been dealing with this issue for months and paid over $2,000 to have the issue fixed, which was NEVER actually fixed! After dealing with Peter M, a service representative for months, I began asking to work with a manager in getting the car fixed! After picking up my car, I saw my brake light was on. Peter M mentioned that "I needed new brakes" and that it would cost me "about $800.00" to get them fixed. I brought my car to Deer Park Quality Auto for a second opinion to see that my brake sensor was cut and was explained that there was no way that this happened by driving the car, instead it was yanked or cut to trigger the brake sensor. Peter M was reluctant on multiple occasions to allow me to speak with Dave C, their service manager, often picking up his line and saying he was unavailable. On two occasions I called under a to speak with Dave immediately after being denied access by Mr. M who said he was out of the office, and reached him after calling back under a different alias. Finally being able to reach Mr. C, I explained the issue at hand. He seemed distraught and eager to help me fix my car. After about one week of them having my car, they had a BMW corporate representative come down to take a look at the car, finding the problem. After denying to pay an ADDITIONAL $1300.00, the car was returned to me missing my BMW emblem on the front. They tried to tell me that the emblem was missing upon receiving the car. My car was returned to me about 5 times with them stating that the issue at hand had been fixed. In August of 2013 I paid for them to replace or change things in my car, that didn't affect or change my initial and only reason for bringing in the car. BMW of Habberstad has refused since then to actually fix the issue, seeing that they had to bring down a BMW corporate representative, it seems as though they were doing guest work all along.
