About one month ago, I noticed the brake and battery lights on in my 97 Nissan Sentra (83Kmile). I brought my car to a Nissan dealer service center. I also ordered a 3K mile oil change with 100 points coutesy check. After the check,they replaced the alternator and the left outer CV boot.
Right after that, my car started leaking oil, and there was an oil burning smell in the car. I went back to the dealer several times. They first insited that there was no leaking till last week, they acknowledged that the " Oil pan gasket leaking" and " Front crank seal seeping", but asked me to pay 500$ to fix.
But that was not the worst yet! Last weekend, 3 weeks after the service, I could not start the engine. I could hear the cranking. Today, I had car towed to the dealer. They told me to replace the starter, which will cost 400$.
My questions: (1)Was the initial diagnosis correct? i.e. was the symptom (the brake and battery light on ) really caused by the alternator problem? (2) was the oil leaking incurred by service (oil change, alternater replacement)? (3) is the starter problem related to the replacement of alternator?
The dealer denied all of these. What should I do on this issue?
My auto knowledge is almost zero. I would appreciate it very much if you could me any help.
