What stands out
Among the 10 model years of Acura MDX in our records for cruise control problems, this one ranks #2 by owner-complaint volume.
No new NHTSA cruise control complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
The failure pattern owners describe
Owners report four distinct failure patterns in the 2014 MDX cruise and throttle systems. The most serious involve unintended acceleration: a vehicle lurched forward entering a garage and crashed through the back wall into the home; another accelerated from a standstill and hit a wrought iron fence; a third flew across a driveway at 30-40 mph down a hill into a tree, injuring the passenger with a compressed spine fracture.
Adaptive Cruise Control has a separate failure mode where the system brakes hard for no reason—dropping 10 mph instantly on flat, open highway with no vehicles detected in range. One owner experienced this twice in six weeks; another notes ACC fails to re-accelerate when traffic ahead speeds back up, a serious hazard. Owners also report ACC sluggish in responding to actual traffic, creating additional collision risk.
A third pattern involves cruise control and throttle hesitation: the vehicle lurches and hesitates between 30–45 mph, with visible RPM jumps on the gauge. One owner reports temporary loss of vehicle control.
Forward Collision Warning triggered false alerts at highway speed (65–70 mph), prompting drivers to brake hard with no actual threat present, risking rear-end collision.
At least one vehicle was reported to the manufacturer but never diagnosed or repaired, and is not covered by NHTSA campaign 15V301000.

Failure modes owners describe
Adaptive Cruise Control (ACC) Hard Braking
ACC engages sudden, hard braking without warning or collision detection, dropping speed 10 mph instantly or more. Occurs when no vehicle is detected within range, when vehicles merge in front, or when followed vehicles slow down—braking does not ease and vehicle fails to re-accelerate when traffic speeds back up.
When: During highway driving at 65-70 mph; some instances within 6 weeks of ownership
Symptoms owners cite: Sudden hard deceleration without warning; No collision warning message displayed; Vehicle does not re-accelerate when traffic in front speeds up; ACC sluggish or inconsistent when detecting vehicles ahead; Braking occurs with no obstacle or vehicle in range
Unintended Acceleration / Stuck Accelerator
Vehicle accelerates suddenly without driver input or with minimal throttle application. Incidents include lurching forward at low speeds (5 mph while entering garage, backing up from driveway), high-speed acceleration across driveway, and independent acceleration while driving. Brakes do not respond or do not prevent collision.
When: While backing up driveway; while entering garage; at 5 mph; during normal driving; one incident at 44,323 miles
Symptoms owners cite: Vehicle lurches or accelerates forward without driver input; Brakes fail to respond or do not prevent impact; Vehicle crosses driveway and descends hill into tree at estimated 30-40 mph; Vehicle crashes through garage into home; Vehicle crashes into fence
Repairs/costs cited: One incident resulted in spinal fracture (L2 compressed vertebra) requiring lumbar brace; significant home and vehicle damage; airbags deployed in one case; no airbag deployment in low-speed crash
Recalls/TSBs owners mention: Manufacturer notified in at least two cases; vehicle not diagnosed or repaired; not covered under NHTSA campaign 15V301000
Cruise Control / Throttle Hesitation and Lurching
Vehicle hesitates, lurches, and loses smooth acceleration during cruise control or normal driving. RPM gauge shows jumps and hesitations. Vehicle fails to maintain constant speed, especially on slight grades or between 30–45 mph. Condition requires aggressive acceleration or dropping speed below 20 mph to resolve.
When: Consistently during 30-40 mph range; at 35 mph and 45 mph; early after vehicle purchase
Symptoms owners cite: Hesitation with acceleration; Sudden lurching after hesitation; Inconsistent RPM (visible on tachometer); Failure to maintain constant velocity; Difficulty maintaining speed on slight grades; Temporary loss of vehicle control reported
Forward Collision Warning (FCW) / Sensor Malfunction
FCW alerts trigger inappropriately at highway speeds (65-70 mph) with no actual collision threat. Drivers report applying emergency brakes in response to false warnings, creating rear-end collision risk. Indicates sensor fault rather than a true collision warning event.
When: During freeway driving at 65-70 mph
Symptoms owners cite: FCW flashes / alerts without collision threat; Driver applies emergency brakes in response to false alert; Risk of rear-end collision from following traffic

Common questions
How serious is the cruise control problem on the 2014 Acura MDX?
It's a meaningful issue. 11 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 8 complaints that reported odometer mileage, most cruise control failures cluster between 14,200 and 44,323 miles, with the median around 26,000. A quarter of owners report trouble before 14,200; a quarter make it past 44,323. 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.
