2003 Altima 3.5, Occasionally Won't Start

Today I drove my 2003 Altima 3.5, 600 miles through heavy rain and fog, etc. Stopped several times for lunch and gas. Car performed beautifully all the way.

When I reached my destination I parked it on the street and my wife commented that I was slightly blocking the neighbour's driveway. I tried to start it and absolutely nothing. No sound from the engine whatsover, only the dashboard lighted up.

I went out 15 minutes later and it started first turn on the ignition.

This has happened about 6 times now and is getting a little disconcerting although I haven't been stuck yet.

Any ideas on the cause or how how to diagnose the problem.

Does it need to be towed to the dealership so they can immediately check the "codes" or can they still do this after a few days?

Clean/scrub Your Battery Terminal And Clamps With A Wire Brush.

Thank you very much for the prompt & informative reply.

You are quite correct. Both terminals were badly corroded and were certainly in need of a thorough wire brushing and cleaning which I completed. I am very hopeful that this overdue maintenance will correct the problem.

Makes you wonder why you pay the dealer big $$ to do the various maintenance checks that they are trained for and should know to look for.

Two months later and through all types of cold, hot, wet & wintry weather, I've never had a further problem starting after cleaning the battery terminals.
