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 report the cruise control and throttle control systems as unreliable and occasionally dangerous. Two drivers experienced unintended acceleration with the pedal sticking to the floor at very low mileage (3,500–4,300 miles); both had to shift to neutral and kill the engine to stop. Another owner had the cruise control engage on its own at 70 MPH, forcing acceleration until braking intervened.
The most consistent failure is aggressive downshifting on downhill grades while cruise control is active. Multiple owners describe sudden hard shifts to lower gear with RPMs spiking to 5,500+, loss of temporary speed control, and the brake pedal or cancel button failing to disengage the system until the van slowed to 10–15 MPH or lower. One dealership advised a customer not to use cruise control instead of fixing it.
Other reports include electronic throttle control warning lights with no-start conditions (recurring three times in three weeks), loss of power below 20 MPH, complete failure to decelerate when releasing the accelerator after a TIPM module replacement, and a cruise control button that requires 6–12 presses to turn on. Dealership diagnostics have been vague—one blamed aftermarket floor mats, another found nothing wrong despite the incident—and Chrysler has offered no recalled parts or service bulletins in these narratives.

Failure modes owners describe
Stuck accelerator / unintended acceleration
Accelerator pedal becomes unresponsive to release, sticking to the floor or forcing the engine to high RPMs despite driver's attempt to slow. Occurs during normal acceleration and when driver is not actively using cruise control. Event is abrupt and requires brake application, shifting to neutral, or engine shut-off to stop.
When: Very low mileage (3,500–4,300 miles reported in one case); reported at 51,500 miles in another; intermittent recurrence
Symptoms owners cite: Accelerator pedal sticks to floor or remains depressed without driver input; Engine revs to redline (5,500+ RPM) despite foot off throttle; Continued acceleration even while braking; Pedal felt like someone pressing on gas while driver applies brakes
Codes mentioned: Transmission overheating code (6 starts prior)
Repairs/costs cited: One dealership blamed aftermarket floor mats; no repair performed. Unresolved in other cases.
Recalls/TSBs owners mention: Manufacturer offered no assistance in one documented case. Dealer advised customer to stop using cruise control.
Cruise control causes unintended aggressive downshift going downhill
When cruise control is engaged at highway speeds on downhill grades, the transmission suddenly downshifts hard to a lower gear, causing RPMs to spike (5,500+). Brake pedal and manual cancel attempts fail to disengage cruise control immediately; vehicle regains control only when shifted to neutral or speed drops below 10–15 MPH. No warning lights activate during the event in most cases; check engine light may appear afterward.
When: 45–70 MPH, specifically on downhill sections; can recur within hours or days of first occurrence; also reported at 31,000–36,000 miles
Symptoms owners cite: Sudden hard downshift while cruise control active on descending grades; RPMs jump to 5,500+; Loss of control and momentary drop in speed; Brake and manual cancel button fail to disengage cruise control; Engine light illuminates after event; Vehicle lurches forward despite braking
Codes mentioned: Check engine light (delayed)
Repairs/costs cited: No parts or costs documented. Customer placed vehicle in neutral to regain control.
Recalls/TSBs owners mention: One dealer advised customer not to use speed control; no recall or TSB mentioned.
Cruise control engages automatically without driver input
Cruise control system activates on its own while vehicle is at cruising speed, causing unexpected acceleration without the driver pressing the cruise control button. Braking disengages the system but it may recur intermittently.
When: Approximately 70 MPH; recurring intermittently; mileage range 51,500–51,900
Symptoms owners cite: Cruise control engages unexpectedly without driver activation; Vehicle accelerates to higher speeds unintentionally; Disengages when brakes are applied
Repairs/costs cited: Aftermarket floor mats blamed by dealer; no repair completed.
Recalls/TSBs owners mention: Manufacturer offered no assistance.
Electronic throttle control malfunction / no-start condition
Electronic throttle control light and check engine light illuminate; vehicle fails to start. Problem recurs intermittently (three times within a three-week span in one report). Root cause uncertain; could involve throttle control module or main electrical module.
When: Mid-December through January 2017; vehicle may restart after waiting days
Symptoms owners cite: Electronic throttle control warning light on; Check engine light on; Vehicle fails to start; No-start condition clears after prolonged waiting period
Codes mentioned: Electronic throttle control light, Check engine light
Repairs/costs cited: No repair completed; customers unclear on root cause.
Loss of power / speed limited below 20 MPH
Vehicle loses power acceleration when traveling at 20 MPH and will not accelerate above that speed. Electronic throttle control warning light illuminates. Occurred twice. System was reset and vehicle reported repaired, but failure mode and resolution unclear.
When: Approximately 26,116 miles
Symptoms owners cite: Loss of power while driving at low speed (20 MPH); Vehicle cannot accelerate above 20 MPH; Electronic throttle control warning light illuminated
Codes mentioned: Electronic throttle control warning
Repairs/costs cited: Electronic throttle control reset; vehicle repaired.
Brake and accelerator incompatibility during cruise control
When driver attempts to decelerate by applying brakes while cruise control is active, the vehicle continues to accelerate instead of slowing. Conflict between brake input and cruise control command.
When: 65 MPH; 43,731 miles
Symptoms owners cite: Speed increases despite brake application; Cruise control does not disengage when brakes engaged; Conflicting system behavior
Recalls/TSBs owners mention: Manufacturer made aware; vehicle not repaired.
Deceleration failure after TIPM module replacement
Following TIPM (Totally Integrated Power Module) replacement for a faulty light issue, vehicle loses the ability to decelerate when the accelerator pedal is released. Brakes still function but system fails to respond to normal throttle release.
When: During nighttime in rain; immediately after TIPM replacement
Symptoms owners cite: Vehicle does not decelerate when foot removed from accelerator; Normal throttle response absent; Brakes still functional; Multiple fault lights on instrument cluster
Codes mentioned: Multiple fault codes (instrument cluster warnings)
Repairs/costs cited: TIPM module was replaced; deceleration issue appeared post-repair.
Cruise control button requires multiple presses to engage
Cruise control button becomes sluggish or unresponsive, requiring 6–12 button presses to activate the system.
When: Since June 23, 2016; intermittent on/off behavior, worse in cold weather
Symptoms owners cite: Cruise control button unresponsive; Requires 6–12 presses to activate; On/off cycling issue; Worse in cold conditions

How serious is the cruise control problem on the 2010 Dodge Grand Caravan?
It's a documented issue but not catastrophic. 13 complaints have been filed. Repairs average $600 and most owners catch it before it causes a breakdown.
At what mileage does the cruise control typically fail?
Across the 12 complaints that reported odometer mileage, most cruise control failures cluster between 31,000 and 75,000 miles, with the median around 48,305. A quarter of owners report trouble before 31,000; a quarter make it past 75,000. 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.
