Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2009 135I Convertible.
The 2009 BMW 135i Convertible rides on the E88 platform as a passenger car paired with a six-speed automatic transmission that returns 17 mpg city, 26 highway and 20 combined. Its reliability record shows 79 owner complaints filed, with air-bag issues leading the categories and eight recalls issued for the model year. That volume of campaigns and the prominence of restraint-system reports place this vintage near the more troubled end of this model's history, suggesting buyers should verify recall completion and air-bag service records before purchase.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2009 BMW 135I Convertible lead in one area — the air bags, 18 of 79 reports (23%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 0 of the reports describe a crash and 2 a fire — a small share of the total, but worth weighing against the air bags pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
