Oil cap will not unscrew on 2008 Nissan Altima manual transmission that is leaking oil.
The following had to be fixed all on one visit: my alternator replaced; top motor mount replaced, brake sensor replaced, battery replaced, and had an oil cooler leak fixed. All was covered with my extended warranty ($858 otherwise). It has had a total of 4 batteries, 2 alternators, 2 manna folds (a recall), new shocks and struts (I paid for) and my transmission warranty was extended to 120,000 miles. (there was also another recall to the fuel tank but can't remember any specifics). I take great care of my car, have it maintained regularly, and only use quality gas. This is my fourth Nissan and I am greatly disappointed in the quality. I am debating as to wether or not I should trade it in.
