To compound matters, the 2015 edition of the Jetta TDI was the last model made for American markets and the Jetta TDI was discontinued after the 2015 model year. Following the Volkswagen diesel emissions scandal, all other diesel Volkswagen models were also discontinued. As a result, there are no comparable models currently available unless you decided to buy a gas-powered Jetta.
If you ever decide to upgrade, the current Volkswagen warranty is a 4-year, 50,000-mile basic warranty (bumper-to-bumper) and a 4-year, 50,000-mile powertrain warranty.
