BMW Z4 Reliability through March 31, 2013
General NotesModels and statistics marked with an asterisk (*) have very low sample sizes. These results, visible only to logged-in members, provide only a rough estimate of car reliability.Any result under 20 repair trips per 100 cars is likely a result of the small sample size, and should be expected to increase to 20 or so in future updates.
New models often start out with high repair rates, and then improve as the manufacturer identifies and addresses common problems. MethodologyOnly successfully completed repairs are currently included in the analysis. Routine maintenance, most wear items, recalls, and problems fixed with just a reflash or warning light reset are not included.
