The reliability of Teslas has taken a nosedive, according to a recent study, which reveals a surprising trend in the used car market. The days of scalpers flipping Teslas for profit are long gone, as the prices of used EVs have plummeted in the past two years. This shift has significant implications for Tesla owners, especially those with older models. The study, conducted by Consumer Reports, analyzed real reports from vehicle owners, highlighting a range of issues, from minor inconveniences to severe, costly problems. While previous studies attributed Tesla's issues to isolated engineering blunders, this latest research focuses on Teslas made between 2016 and 2021, revealing a more widespread reliability crisis. Despite the resolution of premature Model S battery failure issues, Teslas now rank as the least reliable automaker among 26 surveyed, with older models trailing behind. Interestingly, newer Teslas, up to three years old, are in the reliability sweet spot, particularly the Model Y. The used Tesla car market has seen a dramatic price drop since its peak in 2022, with pre-owned EVs like the Model 3 now costing less than gasoline cars and lingering on lots. Japanese brands like Lexus continue to dominate the top spots in both new and used car reliability rankings. This study underscores a critical juncture for Tesla, prompting owners to reconsider their long-term reliability expectations and potentially impacting the used car market's perception of the brand.
