Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2011 135I Coupe.
The 2011 BMW 135i Coupe sits on the E82 platform as a compact passenger car, built around an engine that calls for a 6.9-quart oil capacity filled with 15W-40, 10W-40, or 10W-30 API SJ lubricant and paired with a seven-speed S7 automatic transmission. EPA testing pegs fuel economy at 18 city, 25 highway, and 20 combined mpg, offering a clear-eyed baseline for any researcher evaluating running costs. The reliability record, however, is where this model year demands attention: 66 owner complaints have been filed, with airbag issues standing out as the most frequently cited concern, and nine recalls attached to the vehicle — a footprint that defines the 135i's standing in its reliability history and signals where investigators should focus their scrutiny.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2011 BMW 135I Coupe lead in one area — the air bags, 19 of 66 reports (29%), well ahead of the next concern. That matters, because the air bags are also the target of recall 20V-017 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 1 of the reports describe a crash and 4 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.
All 66 complaints on record, top 8 components.
