Dear All,

I have replaced the alternator from Nissan dealer and have put a new
battery few weeks back.  
I also had dignostic test done at nissan few days back and they did not
find any problem.
The car was running fine untill yesterday while driving,
there was power failure and car stopped on the road.
Follwing four lights came on at the same time -

1)battery light(charge warning light)
2)brake warning light
3)malfunction indicator light
4)engine oil pressure warning light

when i tried cranking after few minutes ,car started and all the lights
went off.
At this point it just feels unreliable to drive without fixing the problem
as the car may break down again. would it be the alternator again? I just
had oil change done at pepboyes few days back. the car has 88 k
miles.would it be a better idea to go for 90 k service from nissan which
costs $400.00

Any advice is appreciated.

Thanks
