2016 Acura MDX: adaptive cruise control problems

Filed Nov 22, 2025 · Driver assistance · NC

Cruise control stopped working 5 years ago after ACC LKAS stopped working. I have had the car into multiple Acura certified dealerships attempting to repair and no one has been able to determine the issue.

The Acura MDX, which had always been serviced at an Acura dealership, had 121,007 miles on it when the transmission completely failed without prior warning. I was driving with the d cruise control on at around 70 mph when I took the car off cruise by touching the brake to take the exit ramp onto I-10. I suddenly lost power, the engine still runnning, the car was on the exit ramp, which was uphill and exiting from I75 South. I had to coast to a stop and stopped between in a trouble area between the exit ramp and the fast lane on I10 east, which the wrecker driver said left the car exposed in a “kill zone.” After stopping, the car would start but all four wheels were locked and the wrecker drivers could not roll the car into a safer location to retrieve the car. They nevertheless pulled the car onto the wrecker while in what they described as a “kill zone,” and I also thought the spot I had to stop was extremely dangerous. The dealership, Key Acura in Gainesville, Florida, advised the transmission needed to be replaced at a cost of $7,200. After that I sold the car to an online site at a price that was basically for junk.

On Saturday [XXX] I was travelling on [XXX] from Orangeburg to Atlanta. I did was not using cruise control but the system was enabled. Enabling the cruise control system on my automatically enabled the LKAS(Lane Keep Assist) feature on my car. On at least two other occasions, specifically going around corners at low speed, I've had the LKAS system grab the wheel and steer the car aggressively to the left. On these prior occasions we were travelling at low speed and the road conditions were questionable as in striping of the roads were not clear. On [XXX], the road conditions were optimal minus being a little wet due to rain. The LKAS unexpectedly turned the wheel hard to the left going around a corner at 55mph and into oncoming traffic. Before I could regain control of the vehicle it veered into a ditch, across a culvert and landed in the ditch on the other side of a driveway. If not for sheer luck both I and the oncoming driver would be dead and the car destroyed. I am taking the car to a dealer tomorrow to have them inspect the LKAS. There were no warning lamps, message or any other alerts prior to the LKAS taking over the steering. Upon coming to a rest and recovering, I inspected the vehicle and found no damage save a deflating front tire and was able to drive the car back to Atlanta. I do not have Dashcam footage of the other occurrence of the LKAS malfunctioning but I did have a DashCam in the car and running when this latest incident occurred and if possible I will attach it to this complaint. Prior to submitting this complaint and contacting a dealership to have the car inspected I did put in my VIN and research if there had been any recalls on the LKAS system in my model year vehicle. I can confirm that there were not but there had been recalls for earlier versions of the same vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on an interstate highway at 73 mph, under cruise control, at night, as the road started to incline up a hill my vehicle started losing power. The highway is two lanes each way, and I was in the left-hand lane passing a slower vehicle that was in the right-hand lane. There were cars behind me in my lane. When my car started losing power, the check-engine light came on along with some other indicators. I attempted to maintain speed by depressing the accelerator, but the car continued to slow down. It was nighttime when this happened, on a pitch-black highway that had been freshly paved. I was able to finally get behind the car I had been attempting to pass and was then able to get into the emergency lane and stop. My car was making a ticking noise. I turned off the car, opened the hood, but it all looked fine. I looked under the car - there were no fluids running out of the car. I checked the oil, and it was at the full mark on the dipstick - I had changed the oil about 1000 miles prior to this event. When I took the car to a local Acura dealer, they told me that the noise I was hearing was "rod knock", and that it would cost about $8000 to repair by purchasing a short block and having them install it. When I started researching the issue I learned that some 2016 Acura MDXs have a known issue of incorrect rod bearing size, but that my vehicle is excluded because it was evidently manufactured before a certain date. My car has only 125,116 miles on it. It is maintained meticulously. Please investigate.

Forward Looking Camera failed at 62k miles, it won't communicate with the computer according to dealership diagnosis on 11-18-2022. Replacement cameras are on backorder, with no availability date. Vehicle is available for inspection. The issue directly affects Forward Collision, Lane Departure and Cruise Control. It no longer warns me if approaching something too quickly. It no longer tells me if I drift into another lane or corrects it. Cruise Control stopped working as well. Distracting lights and beeping when driving, says windshield needs to be cleaned on instrument cluster. Issue began in mid 2022. According to my research, failing cameras seem to be an issue. Replacement camera is approx $1500, plus the labor to install and align.

While driving on the interstate miles in cruise control vehicle started to reduce speed quickly. upon pressing the accelerator (as a semi was right behind me) nothing happened. I attempted to pump the gas pedal in desperation of not being hit as no pull off lane was available. After about 4 minutes vehicle was able to accelerate once again no warning signs or lights came on at this time (i had my 4 young children in the vehicle) extremely unsafe and yet no resolution with said issues. This has occurred 4 times as of yet. #2 dashboard display vehicle in park (P)blinking along with codes; lane departure failure, transmission system failure, blind spot failure.

Attempted to accelerate with pedal while at freeway speeds and after canceling cruise control, vehicle does not accelerate, downshifts instantly to 2nd gear, multiple warning lights on dash, main display reads 'emissions system problem'. Accelerator function returns but transmission is stuck in 2nd gear at freeway speeds and very high engine RPM. Must make emergency stop on side of road and restart vehicle to remedy. Check engine light and 'emissions system problem' warning remain for a day or two following an incident but vehicle drives ok. This issue has occurred on 4 separate occasions. Took to acura dealer after 3rd incident and dealer reported no trouble found.

When driving at highway speeds for at least a half hour and attempting to accelerate, the engine speed will drop to idle and will not respond to accelerator pedal movement for several seconds. When this happens, there are no: warnings, lights, or messages and no fault codes are stored in any of the control modules. This has never happened when using cruise control. This has happened on at least 9 different trips. This is an extremely dangerous condition that has nearly resulted in another vehicle impacting ours from behind, due to the rapid deceleration.

Tl* the contact owns a 2016 acura mdx. While driving 72 MPH with the cruise control activated, the vehicle lurched twice and all the warning indicators illuminated, displaying transmission system failure, fuel emission failure, and lane departure failure. The vehicle stalled and was coasted to the side of the road. The contact attempted to restart the vehicle, but was unsuccessful. The vehicle was towed to an acura dealer (acura of jackson, 828 adcock st, ridgeland, ms 39157) where it was determined that there was a computer glitch. The computer system was reset. The dealer stated that this was a known failure with acura and no permanent remedy was unavailable. The dealer also stated that the failure could recur in 10 to 10,000 miles. The contact was concerned that the failure would recur and took the vehicle to david mcdavid acura of austin (13553 research blvd, austin, tx 78750). The contact informed the dealer that she felt unsafe driving the vehicle and wanted to trade it in for another vehicle. The manufacturer was notified and advised the dealer to attempt to duplicate the failure. The vehicle was currently at the dealer awaiting a new diagnosis and possible repairs. The failure mileage was unknown.
