Our certified technicians in Albuquerque use OEM diagnostics to find the true cause and recommend cost-effective repairs with transparent estimates.

First, note whether the light is steady or flashing; a steady light allows you to drive cautiously to the dealership; a flashing light indicates a serious misfire and you should stop driving and have the vehicle inspected immediately.

Use our convenient online tools to schedule service or view current service specials to save on maintenance.
