What stands out
Owners have filed 26 cruise control 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.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering cruise control on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners describe two main acceleration hazards. The first is cruise control failure: when engaged, the vehicle accelerates 10–25 mph above the set speed, engine RPMs spiking to 4,000–6,000+, and the decelerate or cancel buttons won't stop it—brake pedal is required. This has happened repeatedly on highways and surface streets; one owner disabled cruise control entirely after multiple failures over three years.
The second is sudden, unwarned full-throttle acceleration that occurs independently of cruise control—while shifting into Drive, during normal highway cruising, or sitting at a stop light with foot on brake. Brake pedal demands maximum pressure to slow the vehicle; several owners swerved into driveways or curbs to avoid collisions, and one incident injured a pedestrian. A service bulletin for 5.7L engines (dated May 13, 2006) addressed this, citing a computer module (P2112) defect. Dealers have replaced throttle bodies and computer modules, but failures often recur. One transmission-related complaint describes hesitation and neutral slipping during acceleration on 2WD models, though Chrysler only issued a recall for 4WD. Stalling without warning and stuck accelerator pedals round out the list.

Failure modes owners describe
Cruise control causes uncontrolled acceleration
When cruise control is engaged or reactivated, the vehicle accelerates abnormally to speeds 10–25 mph higher than set. Engine RPMs climb to 4,000–6,000+. Pressing the brake pedal or toggling the cruise control off is required to stop the acceleration.
When: Across model years; several cases reported acceleration occurring during highway driving, after passing slower vehicles, or upon initial engagement
Symptoms owners cite: Vehicle accelerates rapidly when cruise control is set; Engine RPMs spike to 4,000–6,000+; Cruise control decelerate and cancel buttons do not stop acceleration; Brake pedal required to disengage; Accelerator pedal goes to floor
Codes mentioned: P2112
Repairs/costs cited: One owner reported throttle body replacement and software update; one service bulletin (dated May 13, 2006) for 5.7L engine models described the problem and solution. Some owners reported cruise control disabled by mechanics after repeated failures.
Recalls/TSBs owners mention: Service Bulletin for 5.7L engine models. Some dealers reported no known issues or inability to replicate. One owner cited NHTSA Campaign 14V438000 (Electrical System) but stated repair parts were unavailable.
Unintended full-throttle acceleration not related to cruise control
Vehicle suddenly accelerates to full throttle without driver input, often when shifting into Drive or while cruising at normal speeds. Brake pedal requires maximum pressure to stop; in some cases, neutral or shutting off the engine was necessary.
When: Mileage reported 19,382 to 101,000 miles; one case noted cold-weather start, another warm-weather recurrence
Symptoms owners cite: Sudden, unwarned acceleration to full throttle; Accelerator pedal goes to floor; Brake pedal requires firm or maximum pressure to slow vehicle; Vehicle does not decelerate normally; Occurs when shifting into Drive or while cruising
Codes mentioned: P2112
Repairs/costs cited: One owner reported computer module replaced twice without resolving the issue. One case involved a 5.7L HEMI requiring engine stall and restart. Some owners had throttle body replaced; others disabled cruise control.
Recalls/TSBs owners mention: Chrysler stated no recalls applied; dealers claimed inability to replicate. Service bulletin for 5.7L engine addressed this. One owner received recall notification 14V438000 but parts were unavailable.
Transmission hesitation and delayed engagement
Transmission fails to engage promptly when accelerating; RPMs climb to 3,500+ before gear shifts. Vehicle may slip into neutral momentarily during acceleration attempts, creating a gap where the vehicle loses propulsion.
When: Reported as ongoing since 2011 and worsening; one case at 10 mph in parking lot
Symptoms owners cite: Hesitation at acceleration; Engine RPMs rise to 3,500+ before transmission shifts; Transmission slips into neutral temporarily; Loss of propulsion during acceleration; Requires vehicle restart to restore normal function
Repairs/costs cited: No repairs cited in complaints; owner notes a recall exists for 4WD models (referenced as 'N23') but was told 2WD does not qualify despite identical symptoms.
Recalls/TSBs owners mention: Chrysler acknowledged a recall (N23) for 4WD models but did not apply it to 2WD vehicles, even though 2WD owners report the same symptoms.
Vehicle stalls without warning
Engine stalls sporadically and unexpectedly during normal driving. One case noted the vehicle shakes as though it will turn off when brake is not firmly pressed.
When: Reported at 70,000–75,000 miles
Symptoms owners cite: Sporadic stalling without warning; Vehicle shakes when brake not firmly pressed at idle; Requires restart to resume operation
Repairs/costs cited: Dealer replaced throttle body and updated software; failure recurred after repair.
Accelerator pedal stuck or slow to respond
Accelerator pedal becomes stuck at the floor or responds sluggishly to driver input. One case noted the pedal extended to the floor when shifting into Drive.
When: Intermittent, with one case reporting warm-weather recurrence
Symptoms owners cite: Accelerator pedal stuck at floor; Slow or no response to pedal input; Pedal extends to floor abnormally; Issue intermittent and unpredictable
Repairs/costs cited: Vehicle pulled over; pedal returned to normal function. Dealer repairs did not resolve intermittent recurrence.

Common questions
How serious is the cruise control problem on the 2006 Jeep Grand Cherokee?
It's a meaningful issue. 26 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 20 complaints that reported odometer mileage, most cruise control failures cluster between 50,000 and 70,000 miles, with the median around 55,000. A quarter of owners report trouble before 50,000; a quarter make it past 70,000. 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.
