TrueDelta Reviews the Reliability And Durability of the Tesla Model S

Tesla Model S Reliability And Durability: Neutral
YearComment
2013 As I write this, the Tesla doesn't have a bad reliability record. It just has a lot of new technology, and no reliability record. The standard warranty is 4 years, 50,000 miles, with the option to double this for $2,500. The standard battery warranty is eight years. Electric cars, with no engine and transmission fluids to change, have far fewer systems to maintain. Even so, Tesla initially required a $600 annual inspection to maintain the warranty. It has recently backed off this requirement, though it continues to recommend the service contract for free roadside assistance, wear items like brake pads and wiper blades, and any necessary hardware upgrades. (It's not clear what the last might include.) full 2013 Tesla Model S review
