Frequently asked questions


  • Do you service Cadillac Escalade, XT5 and CTS models in Smithtown?

    Yes. Our ASE-certified technicians service Cadillacs at our Smithtown, NY shop — the Escalade, the XT5 and the CTS — including oil changes, brakes, suspension, check-engine diagnostics, and engine and drivetrain repair, all backed by our 12-month/12,000-mile warranty.
  • My Escalade rides rough or sits low overnight — can you diagnose that?

    Yes. Escalades use load-leveling and Magnetic Ride suspension, and both the air components and the magnetic struts wear out and leak with age. We test the system and show you which corner is actually failing, because replacing all four when one is bad is a common and expensive mistake.
  • The 6.2-liter V8 in my Escalade uses oil and ticks — is that normal?

    It is common rather than normal. GM V8s with cylinder deactivation can develop lifter and oil-consumption problems, and the fix depends on which of those you actually have. We measure consumption and check the lifters properly instead of assuming, so you are not paying for the wrong repair.
  • Can you diagnose Cadillac electronic and module faults?

    Yes. We scan every module rather than just the engine, which matters on a Cadillac where a fault in one control unit often lights up warnings somewhere unrelated. If a repair genuinely needs dealer-only programming, we will tell you that up front.
  • Do you offer a warranty on Cadillac repairs?

    Yes — every repair we perform is covered by our 12-month/12,000-mile warranty, using quality parts sourced through Worldpac and Technet. We are a Certified Auto Repair shop, and that warranty travels with the vehicle.

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!"
