My model car has a recall on the fuel injectors. My vehicle's fuel injectors have misfired and have cause the check engine light to remain on in my car. I have contacted bmw several times about this issue. They have told me multiple stories as to why they will not honor my car under this recall. One reason they give is my VIN #, even though my car is the same make and model as the recall with the same issue. Then they say my car is out of warranty. I thought the purpose of a recall is that it repairs your car even if it's out of warranty. I have spent over hundreds of dollars trying to correct this problem, and the problem still exists. Bmw will not reimburse me or fix the car under the recall that I know my car falls under. The recall is even listed on my failed dmv inspection report, and they are still not cooperating. Is there something you can do? My car will not pass inspection, and it's the only car I have.
