Among the 10 model years of Acura MDX in our records for cruise control problems, this one ranks #3 by owner-complaint volume.
The failure pattern owners describe
Buyer takeaway: Multiple 2016 Acura MDX owners report unintended acceleration, transmission stalling, and hard shifting that dealerships claim is normal or refuse to repair. Collision mitigation braking and park disengagement issues also present serious safety concerns with minimal manufacturer support.
Owners of 2016 Acura MDX vehicles describe unintended acceleration as the most serious and recurring problem—the vehicle accelerates without input, won't slow down when braking, and continues speeding downhill. One owner's vehicle accelerated when driving over a speed bump at 20 mph and hit another car; another reported acceleration at just 5 mph when attempting to brake. Dealerships told owners the behavior is normal for this transmission type and refused repairs or blamed the vehicle's design.
Transmission stalling presents a separate hazard. Vehicles suddenly lose power on highways, drop into Park mode, or won't respond to throttle and only idle. One owner's vehicle was quoted $7,100 for transmission replacement at 42,500 miles. Dealerships consistently said they found nothing wrong despite multiple occurrences.
Owners also report hard, jerky shifts with grinding noises, particularly in lower gears. One owner replaced a timing belt pulley without resolution. A technical service bulletin (TSB 15-054) exists but no recall has been issued despite owner complaints.
The steering wheel shift buttons can be accidentally hit, causing abrupt loss of power and requiring an engine restart to restore operation. One vehicle rolled backward from Park on an uphill. Collision mitigation braking failed to reduce speed during a low-speed curb strike. Additionally, shift control labels wear off, creating confusion about which button selects Park.

Failure modes owners describe
Sudden Acceleration — Unintended Throttle Response
Vehicle accelerates without driver input or continues accelerating after releasing the throttle. Occurs during normal driving, at intersections during braking, and over speed bumps. Owners report the vehicle won't decelerate as expected and poses collision risk. Some describe downhill acceleration in particular.
When: Within first few months to 6 months of ownership; documented at 64,053 miles and 300 miles; throughout ownership
Symptoms owners cite: Vehicle continues accelerating for several seconds after driver releases accelerator; Vehicle accelerates when attempting to brake at low speed (5 mph); Unintended acceleration when driving over speed bump at 20 mph; Vehicle accelerates downhill while in motion; No warning lights or inconsistent warning behavior
Repairs/costs cited: Dealership performed software update and transmission flush on complaint #1 but issue persisted; dealership stated condition is 'not considered hazardous by Acura USA' and common to vehicles with that transmission type. Complaint #4 diagnosed as 'performing as designed.' Complaint #3 vehicle not diagnosed. Complaint #7 quoted $7,100 for transmission replacement.
Recalls/TSBs owners mention: Acura Client Services declined to help beyond directing owners to dealership. Acura dealership in Mission Viejo stated condition is known to other Acura vehicles with same transmission and won't be repaired. Warranty claim denials cited in complaint #7.
Transmission Stalling and Loss of Power
Vehicle suddenly stalls or loses ability to accelerate while driving, particularly on highways. Often accompanied by transmission downshift to Park mode or D-gear indicator flashing. Owners feel loss of vehicle control.
When: Within few months of new purchase; multiple recurring episodes; complaint #7 at 42,500 miles
Symptoms owners cite: Vehicle stalls in middle of road and cannot accelerate to pick up speed; Loss of vehicle control on highway; D-gear indicator flashing on dashboard; Transmission downshifts to Park while driving; RPMs rise but vehicle won't move forward, only idles; Engine light comes on, then turns off after restart
Repairs/costs cited: Dealership unable to find issue on first two visits (complaint #2); claimed issue was fixed after few days but recurred. Complaint #8 dealership found nothing wrong despite six occurrences. Complaint #7 dealer quoted $7,100 for transmission replacement.
Recalls/TSBs owners mention: Acura Client Services opened case and assigned regional manager but took no action, citing owner must return loaner vehicle despite safety concerns. No TSBs or recalls cited for this failure.
Hard Transmission Shifts with Grinding Noise
Transmission shifts abruptly and jerks during gear changes, accompanied by grinding or chirping sounds from drivetrain. Most pronounced in lower gears. Owner awareness of TSB 15-054 but no recall issued.
When: Throughout ownership; complaint #5 timing belt pulley replaced without resolving issue
Symptoms owners cite: Hard, abrupt gear shifts; Grinding or chirping sound during shifts; Car jerky when shifting gears while driving; Particularly pronounced in lower gears
Repairs/costs cited: Complaint #5 owner replaced timing belt pulley but grinding/jerking persists. Complaint #10 owner cites technical service bulletin TSB 15-054 but states no recall has been issued despite multiple complaints.
Recalls/TSBs owners mention: TSB 15-054 exists for this issue but no recall has been issued. Manufacturer has not addressed the durability of shift quality.
Inadvertent Gear Selector Engagement — Steering Wheel Button Control Issue
Drive mode selector buttons (1, 2, 3) mounted on steering wheel can be accidentally hit by driver, causing abrupt loss of power and vehicle not responding to throttle. Vehicle must be shut off and restarted to restore normal operation.
When: Multiple occurrences at different times; complaint #5 incidents in parking lot and traffic
Symptoms owners cite: Accidental button press on steering wheel slows car abruptly; Car won't move forward after inadvertent button press, only idles; Vehicle becomes unresponsive to accelerator input; Requires engine shutdown and restart to restore operation
Repairs/costs cited: No repair noted; appears to be design/control placement issue.
Collision Mitigation Braking System Insufficient — Frontal Impact
Forward collision mitigation braking system does not engage or engage sufficiently during a low-speed turn and curb strike. Vehicle speed not reduced to mitigate damage from side-frontal collision with fixed object (iron pillar approximately 2 feet high).
When: Right-hand turn at 20–25 mph; traveled less than 2–2.5 car lengths before impact
Symptoms owners cite: Vehicle speed not reduced by collision mitigation system; Braking system failed to engage or provide adequate braking force; Vehicle took full impact of collision without speed reduction; Low-height fixed object (iron pillar) not detected/avoided by system
Repairs/costs cited: Vehicle involved in collision and towed; no repair information provided.
Recalls/TSBs owners mention: No manufacturer response documented in complaint. System design may not account for low-height objects.
Steering Wheel Control Labels Wearing Off
Letters printed on steering wheel shift control buttons wear away with normal use, making it unclear which button corresponds to Park mode. Owner notes this affects both their 2016 Honda vehicles (note: complaint submitted for Acura but references Honda as well).
When: Normal use over ownership period
Symptoms owners cite: Text labels on steering wheel shift buttons fading or completely worn away; Uncertainty about which control selects Park mode
Repairs/costs cited: Honda/Acura offered to pay half the cost of correcting the issue.
Recalls/TSBs owners mention: Honda has acknowledged the issue but only offers to reimburse 50% of repair cost.
Blind Spot Monitor Reporting Failures
Blind spot monitor system reports failure on dashboard in conjunction with transmission stalling events. Not described as standalone failure.
When: Concurrent with transmission stalling in complaint #2
Symptoms owners cite: Blind spot monitor failure reported on dashboard
Vehicle Rolling Backward from Park — Reverse Engagement Issue
Vehicle moves backward when shifted from Park to Drive on slight uphill, nearly causing highway accident. Suggests inadequate parking brake or transmission engagement.
When: Complaint #2, specific mileage not stated
Symptoms owners cite: Vehicle rolls backward when placed in Drive from Park; Occurs on slight uphill; Almost caused accident on highway
Repairs/costs cited: Issue demonstrated to dealer but no repair outcome documented.
