2005 Jeep Liberty cruise control problems
severe 14 complaints filed with NHTSA · avg repair $600 · see cruise control across all vehicles →
Among the 7 model years of Jeep Liberty in our records for cruise control problems, this one ranks #2 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: The 2005 Liberty cruise-control cluster contains serious unintended acceleration and throttle control failures linked to brake defeat, stuck throttles, and at least one engine fire. Owners report multiple crashes, inability to stop vehicles, and limited manufacturer support.
Owners report two dominant failure patterns: unintended acceleration triggered when depressing the brake pedal, and independently stuck throttles that override driver input. In brake-defeat cases, drivers at traffic lights and low speeds found their Libertys surging forward despite foot-on-brake; two crashes and one rollover resulted. One owner reports depressing brake while descending a driveway, the Jeep lunged forward, forcing her into an embankment—the vehicle overturned. Another struck a vehicle ahead at a traffic light, both feet on brake, unable to stop.
Stuck-throttle cases show the throttle locking wide open, forcing continuous brake pressure to maintain control. One owner on a construction-zone merge experienced stuck throttle at 3,900 miles, smelled burning, and watched the Electronic Throttle Control light flash. Dealer diagnosed an APP (Accelerator Pedal Pressure Sensor) failure and ordered the part from Nashville.
One particularly alarming report describes the vehicle catching fire on the highway at 65 mph with no prior impact—all dash lights came on, the hood burst into flames, and the vehicle was fully engulfed in under five minutes. The owner was less than two years into ownership and had serviced regularly. Fire department findings proved inconclusive, but the owner was told unofficially it appeared a vehicle defect caused it. Chrysler declined responsibility.
Additional failures include engine refusal to shut off even after turning the key to off, intermittent inability to accelerate beyond 10 mph, and a post-recall siren noise the dealer dismissed as normal.

Failure modes owners describe
Unintended acceleration when braking
Vehicle accelerates while driver depresses brake pedal, defeating braking ability. Occurs at various speeds from stop to 30 mph.
When: Varies; reports at 25 mph, 30 mph, while stopped at traffic lights, in driveways, and while parked with engine running
Symptoms owners cite: Vehicle accelerates when brake pedal is depressed; Loss of braking effectiveness; Vehicle surges forward uncontrollably; Engine accelerates to 5,000 RPM while parked; Brake pedal depression fails to slow vehicle
Repairs/costs cited: One owner reports dealer replaced accelerator pedal due to corrosion but failure persisted. Other owners did not obtain repairs.
Recalls/TSBs owners mention: Manufacturer advised diagnostic testing. One owner states manufacturer offered no assistance. Most incidents were not reported to or acknowledged by manufacturer.
Stuck throttle / wide-open accelerator
Throttle sticks in wide-open or near-open position independent of pedal input, requiring sustained brake pressure to control speed.
When: 3,900 miles on new vehicle; incidents at various mileages
Symptoms owners cite: Throttle stuck wide open; Engine racing uncontrollably; Rapid speed increase without pedal input; Smell of burning; Electronic Throttle Control warning light illuminates
Codes mentioned: Electronic Throttle Control (ETC) fault
Repairs/costs cited: One owner reports APP sensor (Accelerator Pedal Pressure Sensor) failure diagnosed and part ordered. Owner received loaner during repair.
Spontaneous engine fire
Vehicle catches fire while driving on highway without prior crash impact. Engine fire develops minutes after loss of speed and dashboard lights activation.
When: Less than 2 years old; regularly serviced; highway at 65 mph
Symptoms owners cite: Sudden rapid loss of speed; All dashboard warning lights illuminate; Vehicle hood bursts into flames; Engine fire engulfs vehicle in under 5 minutes; Fire department inspection inconclusive but suspected vehicle defect
Recalls/TSBs owners mention: Manufacturer sent polite decline letter refusing responsibility despite vehicle being well-maintained and under 2 years old.
Loss of deceleration / inability to slow vehicle
Vehicle fails to respond to braking input and continues accelerating; emergency brake also ineffective in stopping forward motion.
When: Approximately 53,400 miles and other mileages
Symptoms owners cite: Vehicle accelerates independently; Brakes do not slow vehicle; Emergency brake ineffective; Vehicle strikes obstacles
Engine continues running after key-off
Engine does not shut off when ignition key is turned to off position; vehicle remains running and eventually seizes from over-rpm operation.
When: While parked with engine idling; occurred at 72,256 miles
Symptoms owners cite: Key turned to off but engine continues running; Engine running at 5,000 RPM uncontrolled; Motor seizes from sustained over-rpm operation
Repairs/costs cited: Neither diagnosed nor repaired
Reduced acceleration / power limitation
Vehicle will not accelerate beyond 10 mph regardless of pedal pressure. Occurs intermittently and cannot be duplicated by service technician.
When: <UNKNOWN>
Symptoms owners cite: Accelerator pedal depressed but vehicle only reaches 10 mph maximum; Intermittent symptom not reproducible by dealer
Repairs/costs cited: Dealership could not duplicate problem; diagnostic test showed no faults
Recalls/TSBs owners mention: Manufacturer contacted but offered no solution
Post-recall noise in throttle area
Loud siren-like sound occurs when accelerator pedal is depressed, starting after dealer completed recall work. Dealership claims noise is normal.
When: After recall work performed; current mileage 35,000
Symptoms owners cite: Loud siren sound when depressing accelerator; No pattern to timing of noise occurrence
Repairs/costs cited: Dealership claimed siren sound is natural operation
Recalls/TSBs owners mention: Dealer performed unspecified recall work

Common questions
How serious is the cruise control problem on the 2005 Jeep Liberty?
It's a meaningful issue. 14 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $600.
At what mileage does the cruise control typically fail?
Across the 13 complaints that reported odometer mileage, most cruise control failures cluster between 20,000 and 72,256 miles, with the median around 35,000. A quarter of owners report trouble before 20,000; a quarter make it past 72,256. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $600 for cruise control repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to cruise control?
No active recalls currently cover cruise control issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
