I had the service engine light come on and took it to the dealership a month back. They said it was a P0174 issue and would cost be 800$ to fix. I indicated that I would like to ensure that was a "real" issue and would come back later. As I drove out of the lot, the service engine light went off!! Great and just what I had been reading on the websites.
Now,a month later the service engine light came back on, but there also seems to be a pinging sound (rattle). so, tool the car back again into the dealership and they say P0171 and P0174 codes both show up and it will be $900 to fix!!
Really frustrated and confused ... Any help appreciated.
