2011 Jeep Liberty — 2.8L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2011 Liberty 2.8L.

Body SUVEngine 2.8LTransmission Automatic 4-spd

The 2011 Jeep Liberty is a KK-platform SUV powered by a 2.8L engine and an automatic 4-speed transmission, carrying EPA fuel-economy ratings of 16/22/18 mpg and requiring 5 quarts of 5W-20 API oil with filter. Owner records show 180 total complaints for this model year, with the fuel/propulsion system flagged as the top concern and three recalls issued. Set against the broader 2000–2012 model history, in which complaint totals span from 6 to 1,807, the 2011 model’s complaint count sits well below that peak, signaling comparatively restrained owner-reported issue volume within the generation.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 8,000 mi; coolant at 104,000 mi. The big-interval services (at 104,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2011 Jeep Liberty occupies a mid-cycle position in its generation, with federal complaint volumes (180) nearly doubling from 2009’s low (108) but still below the 2012 spike (384). Recall activity (3) is modest compared to the 2002–2006 peak (8–14 recalls annually), while investigations (4) and TSBs (87) suggest lingering, though not catastrophic, reliability concerns. Complaint trends reveal a shift toward fuel/propulsion and air bag systems—areas that saw fewer reports in earlier model years—while crash-related complaints (16) remain consistent with the generation’s average. The data doesn’t specify root causes, but the uptick in electrical and engine complaints in 2011 aligns with broader mid-cycle refinement challenges. Relative to adjacent years, 2011’s record is neither the worst nor the best, but its elevated TSB count signals persistent, addressable issues rather than systemic failures. **Takeaway:** The 2011 Liberty is a *marginal* used buy—acceptable if service records confirm TSB repairs, but riskier than the lower-complaint 2009 or 2010 models.
