2023 Z4 Roadster Reliability

There are no recent reliability ratings for the BMW Z4 Roadster and the last model that was evaluated by JD Power was the 2020 Z4, which achieved a mediocre 75 out of 100 for quality and reliability. Hopefully, matters have improved somewhat since. At least recalls seem to be few and far between, with only one registered for the 2022 and 2023 models, both for the same issue of windows that may close even without the key nearby, presenting an injury hazard to occupants. The BMW Z4 Roadster's limited warranty is valid for four years/50,000 miles, there is a 12-year rust-perforation warranty, and three years/36,000 miles of complimentary maintenance is included.
