| From what I've heard Telsa vehicles rare in for warranty repairs at a higher rate than most other new vehicles. "The main problem areas involved the drivetrain, power equipment, charging equipment, giant iPad-like center console, and body and sunroof squeaks, rattles, and leaks." The most common problems involve replacement of the electric motors, warped brake rotors, door handles that fail to slide out as a driver approaches, and numerous squeaks and rattles, which may be more apparent given the very quiet nature of electric propulsion. Other problem areas cited by Tesla owners are leaking cooling pumps for the battery pack, dead windshield wipers, persistent alignment issues with the wheels, and misaligned latches for the front trunklid and the rear liftgate. Thus far, all such problems have been handled under Tesla's four-year/50,000-mile warranty (it's eight years and unlimited mileage on the powertrain)--and owners appear to be pleased with the level of attentiveness and customer service they have received.
But Consumer Reports notes that once the car is out of warranty, such problems could become expensive for owners of older Teslas to fix. http://www.greencarreports.com/news/1100561_tesla-model-s-to... |
Coming from a state run engineering enterprise, where every motor is purchased from the lowest bidder, even the worst quality motors run for decades before even showing signs of any trouble, including mechanical.
For a car like the Tesla, it's hard to believe that the motor will give any sort of trouble.
Also, most electric motors, even those driven by variable frequency drives, are extremely simple in construction and are extremely resilient to shocks and prolonged use.
Almost all modern motors have efficiencies upwards of 97.5%, so you have very less heating losses and mechanical losses even in the most demanding conditions.
