What breaks most on the 2012 Jeep Liberty
- Airbag light / sensor54 complaintsmostly at 39,000–67,000 miles (64,000–108,000 km)
- Engine stalling12 complaintsmostly at 39,000–56,000 miles (63,000–90,000 km)
- Rust / frame corrosion9 complaintsmostly at 36,000–56,000 miles (58,000–90,000 km)
Specific parts named in the 385 owner complaints filed with NHTSA for the 2012 Jeep Liberty (all dates). Miles = the odometer owners typed in (middle half); cost = the repair bills owners wrote in those same complaints, in U.S. dollars. Owners' reports, not confirmed defects.
When problems show up
Most problems on this year showed up between 16,000 and 48,000 miles (26,000–78,000 km) (the middle half of the 123 complaints, of all 145 filed so far, that listed a mileage).
- At 60K, 100K and 150K miles (97K, 161K and 241K km) Past the range where most problems showed up: it has likely had them or dodged them, so repair records matter most.
This is when owners who had a problem reported it, not the odds that one car will have it.
Questions to ask the seller
- Were recalls 17V640000 (seats) and 13V282000 (electrical) done? Ask for the dealer printout, or check the VIN.
- NHTSA has an open investigation into desiccated air bag inflator rupture. Has this car had that problem?
- Is the airbag light off, and were any airbag recalls done?
- Do all the lights, screens and power features work? Has the battery, alternator or any wiring been replaced?
- Any oil burning, leaks or check-engine lights? Ask for oil-change records.
- Jeep sent dealers 110 repair notes for this car. Was this one done: “Adaptive Cruise Control Sensor 1) If you are replacing this part due to the cluster displaying…”?

How serious. Out of all 145 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.
Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

When owners reported problems. From owner complaints to the government.
Most owners who filed a complaint with NHTSA had 16K to 48K miles (26K to 78K km) on the car (123 of all 145 complaints filed so far listed the miles). This shows when people who had a problem reported it, not the odds that your car will have it.
In owners' words
Air bag light is on. Was advised that clock spring needs replaced and that air bags may not deploy in a crash.

Air bag light came on, will not go off. Taking it in to dealer, told not a warranty item. Online forum indicates this is a common problem from a defective component, what if someone cannot afford the $1000 repair?

Recalls 2
- Seats · recall issued 2017
A component within the occupant restraint controller (ORC) may fail and prevent the active headrests from deploying in the event of a rear-end crash.
- Electrical · recall issued 2013
Electrical over-stress of a resistor in the occupant restraint control module may lead to the non-deployment of the active head restraints during a rear impact collision.
Recall repairs are free at any dealer. A recall only matters if it's still open on that exact car, so check its VIN.

No, it is worse than average by government complaints. It drew about twice the average car's complaints filed with NHTSA in its first 3 years, per car sold (Lemon Index 177; 100 is average, lower is better). The Jeep Liberty year with the fewest complaints per car sold since 2010 is 2011.
What are the most common 2012 Jeep Liberty problems?
In owner complaints to the government, the parts named most are airbags (54%), electrical (30%) and engine (6%). That is the share of complaints, not the share of cars that break.
How many recalls does the 2012 Jeep Liberty have?
2 safety recalls (latest: seats). Recall repairs are free at any dealer; check a specific car's VIN at nhtsa.gov/recalls.

At 60K, 100K and 150K miles, a 2012 is past the range where most problems showed up: it has likely had them or dodged them, so repair records matter most. This is when owners who had a problem reported it, not a prediction for one car.

The Lemon Index counts owner complaints filed with the U.S. government (NHTSA) in a car's first 3 years, per car sold, against the average car of the same model years (100 = average, lower is better). It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
