Frequently asked questions


  • Do you service Nissan Altima, Rogue and Pathfinder models in Smithtown?

    Yes. Our ASE-certified technicians service Nissans at our Smithtown, NY shop — the Altima, Rogue and Pathfinder — from oil changes and brakes to suspension, check-engine diagnostics, and engine and drivetrain work, backed by our 12-month/12,000-mile warranty.
  • My Nissan has a CVT — do you service it, and does the fluid matter?

    We do, and the fluid matters enormously. Most modern Altimas, Rogues and Pathfinders use a continuously variable transmission that depends on a fluid specific to it, and neglecting that fluid is one of the main reasons these units fail early. We use the correct specification, not a universal substitute.
  • My Nissan shudders or whines when accelerating — is the transmission finished?

    Not necessarily, and it is worth finding out before you spend on a replacement. A shudder or drone can come from degraded CVT fluid, a failing mount or a sensor fault, and those are very different repairs. We diagnose it properly first — a CVT is far too expensive to replace on a guess.
  • How often does my Nissan need an oil change?

    For most Nissans we recommend every 5,000 miles on synthetic oil, plus an inspection at each visit so small problems get caught early. We check your specific model's schedule and recommend only what your vehicle actually needs.
  • Will servicing my Nissan here void the factory warranty?

    No. Under the federal Magnuson-Moss Warranty Act, Nissan cannot require dealer service to keep your factory warranty valid. We service to the factory schedule and document every visit.

5-star Review by Skylar Cain

"They have a great system that you can see what needs to be done or should be done soon with pictures for each one so you know exactly where the problem is coming from. I have brought my car in many times and it is very fairly priced for the amount of work done. I have always been greeted and treated very well. I can not thank and recommend A&R enough!"

"I wish I can add 100 more stars! The team at A&R were all super helpful and accommodating when I had a last minute issue with my car. All pricing was explained up front and they helped set up a tow truck to pick up my car. They kept me informed every step of the way and made life easier knowing my car was in good hands. I will definitely be coming back for all my mechanical needs for my car. Thanks again!"
