2012 Jeep liberty, 55,000 miles. I stopped at a red light. When the light turned green I hit the gas to move forward and the truck went nowhere for about 5 seconds, when the transmission finally engaged. The truck jerked and I finally went forward. This truck has been checked with an independent mechanic then brought to the dealership as it is still under extended warranty. Very disappointing,…

What stands out
Owners have filed 32 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA powertrain complaint has been filed on this vehicle in over 10 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2012 Jeep Liberty powertrain exhibits widespread and severe issues: transmissions fail repeatedly at low mileage (some under 5,000 miles), shift violently or not at all, and slip into neutral while driving. Transmission pans rust and leak at 36,000–62,000 miles with no warning system, creating fire hazards. Engine misfires recur even after multiple dealer repairs. Owners across multiple states report identical problems that Chrysler and dealerships refuse to fix, sometimes denying the defects exist despite documented case numbers.
The 2012 Liberty's transmission is its biggest problem. Owners report transmission failures starting at under 4,000 miles—vehicles refuse to engage from park or neutral, or slam violently into gear after long delays. One owner experienced three complete transmission failures within 6 months; another's transmission failed at 62,000 miles out of warranty after the pan rusted through at 56,000. Dealerships have replaced this part multiple times for the same customer only to have it fail again weeks later, yet refuse to replace the entire transmission.
Transmission pans corrode and leak at 36,000–62,000 miles despite no warning light and no dipstick for owners to check fluid. One vehicle couldn't move at all once the pan developed holes. Hot leaking fluid creates fire hazards.
Torque converter shudder at 45–50 mph happens consistently—vehicle vibrates like driving over rumble strips—but dealerships dismiss it as normal 'exhaust drone.' Engine cylinder misfire plagues multiple vehicles at 46,000–50,000 miles with lean/rich codes. One owner's misfire returned 3 months and 5,000 miles after the dealer replaced the O2 sensor, PCM, and catalytic converter; the shop then proposed removing the cylinder head.
One vehicle shifted itself from park into reverse while parked with the engine running and rolled backward into a lagoon. Another slips into neutral randomly while driving. A 50,000-mile driveshaft had missing bolts in its front coupling—Chrysler customer care refused to cover the repair cost.
Chrysler dealerships and corporate customer service consistently deny these are defects, refuse repairs, or blame driver behavior on inclines. Multiple case numbers exist (33606208, 30253034, 578 216 92) without resolution.

Failure modes owners describe
Transmission engagement failure and delayed shifting
Transmission fails to engage from park, neutral, or neutral-to-drive transitions. When engagement occurs, it is sudden and violent ('slams into gear'). Delays of 5+ seconds before vehicle moves forward. Problems recur even after dealership visits. Dealer denies fault, attributing it to inclines and electronic throttle behavior.
When: From very low mileage (under 4,000 miles) through higher mileage; recurring across multiple trips and conditions
Symptoms owners cite: Transmission fails to engage from park or neutral; Abrupt violent engagement ('clunks', 'slams') into gear; Delayed response (5+ seconds) when accelerator depressed; Intermittent rough shifts; Vehicle stalls during turns or at intersections
Codes mentioned: P0869 (Transmission fluid pressure/solenoid-related), Check engine light with unknown related codes
Repairs/costs cited: Independent transmission shops diagnosed faulty torque converter and transmission clutch issues; dealership replaced PCM modules, O2 sensors, catalytic converter in one case with recurring failure; one owner paid independent shop for torque converter replacement
Recalls/TSBs owners mention: Chrysler stated no fix or repair available for harsh shift issue; refused to repair transmission; told owners vehicle is safe to drive despite repeated failures; case #33606208, #30253034, #578 216 92 noted
Transmission fluid pan rust and leakage
Transmission pans corrode and develop rust at premature mileage (36,000–62,000 miles). Fluid seeps or leaks onto undercarriage. Owners report no low-fluid warning light and no dipstick to check level manually. Leaking hot fluid creates potential fire hazard, especially on longer highway trips.
When: Typically 36,000 to 62,000 miles
Symptoms owners cite: Visible rust on transmission pan; Fluid leaking underneath vehicle; No warning light for low transmission fluid; No dipstick available for owner inspection
Repairs/costs cited: Pan and filter replacement; one owner cited $1,700+ for rear differential repair following transmission fluid loss code (P0869)
Recalls/TSBs owners mention: Chrysler customer care refused to cover repair costs in at least one case; no recall issued despite widespread reports
Torque converter shudder and whining noise
Vehicle shudders, vibrates, or makes loud whining/warbling noises during highway driving, especially at 45–50 mph at 1500 rpm or lower. Symptom is 100% reproducible. Dealership misattributes issue to normal 'exhaust drone' and refuses to investigate further. Other 2012 Liberty rentals did not exhibit the problem.
When: Reported at 800 miles and recurs during highway driving; at 37,000 miles in one case
Symptoms owners cite: Shuddering or vibration at 45–50 mph and lower rpms; Loud whining or high-pitched warbling noise (described as 'loose flywheel' sound); Feels like driving over rain grooves or rumble strips; 100% reproducible under specific speed/rpm conditions
Repairs/costs cited: No repairs completed; dealership refused service under 'exhaust drone' diagnosis
Recalls/TSBs owners mention: Jeep customer care unable to contact dealership service manager; no resolution offered
Engine misfire and cylinder problems
Multiple owners report cylinder misfires (cylinders 3 and 5 specifically) at moderate mileage. Check engine light illuminates with lean/rich fault codes. Misfire occurs after other repairs (O2 sensor, PCM, catalytic converter) have been performed. In one case, misfire recurred 3 months and 5,000 miles after dealer replaced multiple components; dealership proposed cylinder head removal and engine rebuild.
When: At 46,000–50,000 miles; recurring 3+ months after initial repair in one case
Symptoms owners cite: Engine runs rough; Check engine light flashing; Vehicle hesitates on acceleration; Vehicle stalls during driving
Codes mentioned: P0303 (Cylinder 3 misfire), P0305 (Cylinder 5 misfire), Too-lean and too-rich codes on individual cylinders
Repairs/costs cited: Initial dealer repairs included O2 sensor replacement ($148), PCM module replacement (two modules in one case), spark plugs with boots and wires ($787 in one case), catalytic converter replacement; recurring failures led to proposal for cylinder head removal and engine rebuild
Recalls/TSBs owners mention: Dealership service agent refused to provide transportation for customer with service animal (violation of ADA noted by owner); Chrysler customer service stated no assistance could be provided until dealer completed diagnosis
Transmission shift to reverse without driver input
Vehicle in park with engine running unexpectedly shifts into reverse without driver touching shifter. Car rolls backward off parking pad into lagoon, or rolls into neighbor's vehicle. Dealership and manufacturer did not provide explanation.
When: After vehicle parked in park with engine running
Symptoms owners cite: Shifter moves from park to reverse without driver action; Vehicle rolls backward uncontrollably; Potential 'false park' condition
Repairs/costs cited: One vehicle totaled by insurance after backing into lagoon
Recalls/TSBs owners mention: Manufacturer assigned case number for inspection; no further resolution details provided in narratives
Transmission gear slippage into neutral
Transmission slips into neutral while driving, then shifts back to drive without driver input. Occurs at stop signs, while turning, and during backup maneuvers. Happens even after transmission pan and filter replacement.
When: At various times during driving; one case noted after pan/filter replacement
Symptoms owners cite: Transmission slips into neutral unexpectedly; Transmission shifts back to drive without input
Repairs/costs cited: Pan and filter replaced; issue persisted
Recalls/TSBs owners mention: No recall reported or action taken
Water pump failure
Water pump seized and locked up at low mileage (just over 50,000 miles).
When: At 50,000+ miles
Symptoms owners cite: Water pump locked up
Repairs/costs cited: Replacement required
Rear driveshaft loose bolts and missing fasteners
Front coupling of rear driveshaft found with two missing bolts and additional loose bolts in rear coupling. Discovered at 50,000 miles during maintenance inspection. Owner notes catastrophic loss of life or property could have resulted if driveshaft failed at highway speed.
When: At 50,000 miles
Symptoms owners cite: Missing bolts in front coupling of rear driveshaft; Loose bolts in rear coupling
Repairs/costs cited: No manufacturer-covered repair; owner responsible for cost
Recalls/TSBs owners mention: Chrysler customer care refused to pay for repair (case #578 216 92); no recall issued despite safety implications
Rapid unintended acceleration at startup
Vehicle leaps forward unexpectedly when starting slowly from complete stop, reaching sufficient speed to jump curb and strike street sign.
When: At startup from complete stop
Symptoms owners cite: Rapid unintended acceleration from low-speed start; Vehicle jumps curb and strikes object
4WD system indicator lights and RPM surges
All 4WD indicator lights illuminate on dash while using towing mode in manual. RPM jumps above 3,000. Lights come on and off intermittently. Repaired by pulling related fuse temporarily; dealer adjustment did not resolve. Later trips caused all 4WD lights to illuminate again.
When: At 500 miles during towing; recurred after 60-mile round trip at higher mileage
Symptoms owners cite: All 4WD indicator lights illuminate; RPM surges above 3,000; Lights remain on despite driving
Repairs/costs cited: Dealer made computer adjustment but stated transmission is 'very weak and needs repair' and refused to fix it until transmission completely quits
Recalls/TSBs owners mention: Dealer stated transmission is very weak but refused repair under warranty despite powertrain warranty coverage to 100,000 miles
