2011 Jeep Liberty — 3.7L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2011 Liberty 3.7L.

Body SUVEngine 3.7LTransmission Automatic 4-spd

The 2011 Jeep Liberty is a KK-platform SUV powered by a 3.7L engine paired with a 4-speed automatic transmission, a powertrain returning an EPA-estimated 16 city, 22 highway, and 18 combined mpg that requires 5 quarts of 5W-20 API oil with a filter for service. Across the model's 2000–2012 span, this particular year lands on the lower, more favorable end of the reliability spectrum with 180 total owner complaints and three recalls, far removed from the 1,807 complaints that plagued the 2002 model. Although it does not match the exceptionally low six complaints of the year 2000, the 2011 Liberty's concentration of issues within the fuel and propulsion system means researchers should view it as a relatively stable entry in the lineage, provided they account for those specific drivetrain vulnerabilities.

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; spark plugs every 32,000 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 sits in the latter half of the second generation (20082012), a period that saw a dramatic drop in complaints from the first generation’s peak of 1,807 in 2002. With 180 complaints, 3 recalls, and 4 investigations, 2011 is notably lower than the 384 complaints and 6 investigations recorded in 2012, and it continues the downward trend from the 2008–2010 years. However, its 87 TSBs are higher than the 63 in 2010, and the top complaint areas—fuel/propulsion system (28), airbags (23), electrical system (17), and engine (14)—along with 16 crash and 2 fire complaints, indicate persistent issues without a clear root cause in the data. Compared to the early generation’s massive recall and complaint volumes, 2011 is a relatively stable year, but the uptick in TSBs and investigations from 2010 suggests some emerging problems. Given the data, 2011 is a better buy than the high-complaint early years and the more problematic 2012, but it still carries moderate risk; a thorough inspection of the fuel, airbag, and electrical systems is advisable.
