Owners of late‑model Mazda3 and CX‑5 sometimes report early battery failure, battery drain, or intermittent electrical issues tied to accessories or modules. Many problems are due to undersized and poor quality batteries. Vehicles used in a cold winter climate place high demands on the battery causing it to rapidly degrade or fail prematurely. Faulty electrical accessories or sensors can have parasitic draws which repeatedly drain the battery which causes decreased capacity and premature failure.
What Needs To Be Repaired Or Replaced
Our Mazda technicians test the battery, starter, alternator, and check for parasitic electrical draws; replace defective components with high-quality parts that meet or exceed factory specifications; repairs may include replacing the battery, repairing or replacing faulty switches or modules, and updating computer software when available. We will check for repairs covered by Mazda recall warranties and advise customers on how to get a free warranty repair when available.
