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 failure patterns with the 2018 Jeep Grand Cherokee involving cruise control and acceleration: unintended acceleration that brakes cannot stop, and throttle stickage.
Unintended acceleration with brake failure: Multiple owners report the vehicle accelerating on its own—from park, at a stop, or while driving—and the brakes failing to slow or stop it. One owner reported RPMs maxing out while sitting in park with foot on brake, resulting in a crash through a garage into a living room. Another was unable to stop when approaching a red light and collided with an 18-wheeler. A third accelerated from park at a drive-thru ATM, hitting it despite braking. Several owners state they could not overcome engine power with the brakes, even with hard or two-footed braking. Some recovered control only by shifting to neutral.
Throttle stickage and acceleration issues: Owners report the accelerator pedal sticking, sometimes under floor mats, causing full-throttle acceleration. One owner found the floor mat was not the issue; another resolved it by removing the floor mat. After one case involved throttle-body replacement and wiring work at a dealer, the vehicle continued to independently accelerate. A third report came in after ABS module recall service, with accelerator stickage during gear shifting afterward.
Cruise control malfunction: Two owners report cruise control behaving erratically—speeding up unprompted, or not disengaging cleanly when brakes are applied, causing the vehicle to lurch forward after brake release. These incidents caused crashes and damage.

Failure modes owners describe
Unintended acceleration – brake unable to stop vehicle
Vehicle accelerates unexpectedly (from park, while parked, or while driving) and brakes fail to slow or stop it. Owners report RPMs maxing out, full throttle engagement, and inability to overcome engine power even with hard or two-footed braking. Some recovered control only by shifting to neutral.
When: Mileage 1,240 to 25,000 miles; also reported on vehicles at low mileage (3,500 miles in one case) and at unknown mileage
Symptoms owners cite: Vehicle accelerates on its own from park or while parked; Vehicle accelerates while driving without driver input; Brakes do not slow or stop the vehicle despite being fully depressed or locked; RPMs max out; Vehicle lurches forward aggressively; Brakes cannot overcome engine power
Repairs/costs cited: Jeep inspected vehicle's black box and stated they found nothing; vehicle deemed total loss in one case; other cases resulted in dealer repairs but failure mode not fully resolved
Recalls/TSBs owners mention: Manufacturer was notified in at least one case and a case was opened; black box inspection performed in one case
Throttle pedal stickage
Accelerator pedal sticks, sometimes when fully depressed or under floor mat, causing uncontrolled full-throttle acceleration. Owners report stickage on multiple occasions, and dealer inspection was unable to reproduce or find fault. One owner resolved the issue by removing floor mat; another noted floor mat was not the cause.
When: Mileage unknown for multiple reports; one case at approximately 25,000 miles after throttle body service
Symptoms owners cite: Accelerator pedal sticks when pushed all the way to floor; Accelerator pedal sticks under floor mat (reported by some, ruled out by others); Vehicle enters full throttle uncontrollably; Brakes cannot overcome stuck throttle
Repairs/costs cited: One owner resolved by removing floor mat; throttle body wiring replaced at dealer in one case; dealer unable to reproduce or find fault in multiple cases
Recalls/TSBs owners mention: Jeep Cares advised taking vehicle to dealership; dealer attempts at diagnosis and repair unsuccessful in some cases
Cruise control malfunction – erratic operation and failure to disengage
Cruise control engages and speeds up unprompted while driving, or fails to disengage cleanly when brakes are applied, causing vehicle to lurch forward after brake is released. One owner reported cruise control speed-up incident while on highway; another reported cruise control to resume full speed immediately after brake release.
When: Mileage unknown; one report on I-275 North in November 2022
Symptoms owners cite: Cruise control engages and vehicle speeds up on its own while driving; Cruise control does not disengage when brake is applied; Vehicle lurches forward and accelerates after brake is released; Vehicle speed increases unprompted; Nearly caused collision with vehicle ahead
Accelerator stickage after ABS module recall service
Owner reports three instances of accelerator sticking when shifting gears after having the ABS module repaired due to recall. This issue did not occur prior to that service.
When: Three instances after ABS module recall repair; exact mileage not stated
Symptoms owners cite: Accelerator sticks when shifting gears; Issue occurred after ABS module recall service, not before
Repairs/costs cited: ABS module repaired due to recall the week prior
Recalls/TSBs owners mention: Recall for ABS module was issued and service completed

Common questions
How serious is the cruise control problem on the 2018 Jeep Grand Cherokee?
It's a meaningful issue. 13 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 10 complaints that reported odometer mileage, most cruise control failures cluster between 1,240 and 25,000 miles, with the median around 12,000. A quarter of owners report trouble before 1,240; a quarter make it past 25,000. 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.
