Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
Can you describe the noise your hearing?
Imagine all the things in and around your home that make noise. Does this noise from this car make a noise I can imagine from you comparing it to something else?
Thanks, ***** ***** a whine your hearing.
Are you sure its a 05 Altima 2.5 S?
I ask because that model does not have a CVT.
A whine noise that starts at 50mph, I do not believe that is the exhaust to blame. That is more than likely something spinning. Possible causes:
Try reving the engine in park to see if the noise occurs, if so then suspect a belt driven pulley causing the noise. An exhaust noise would be more like a rattle, or droan, not a whine unless there were a leak but you should be able to hear an exhaust leak just reving the engine.
A tire or alignment or wheel bearing noise would come and go while swerving, so that is an easy test to do.
This is my 1st answer of what can be many. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. At the top of your screen is the rating box that you only get to use once. Please make sure to complete the mandatory rating when ready or reply and say "I am pleased with my answer". Not rating or rating 1-2 stars does not benefit you nor me in any way.
For me to suggest a shop I have never been in would be just a guess. You can go into one Firestone store and get the best service, nicest techs, cleanest shop, and great diagnosis. You can go around the corner into another and get the complete opposite. You would need to make your opinion of the shop you get to inspect it based on talking to them in person and looking around at the store.
Nissan engines are great, they rank right up there with Toyota and Honda. As for any engine it all depends on how well it is cared for. You can go to any Honda or Toyota dealer and see dozens of cars under warranty getting engine repairs. It all depends on how well the engine is cared for.
I see nothing that stands out bad in that report.
If your not able to check the car over yourself top to bottom to see if any concerns are found then pay a shop an hour of labor to do so for you.
