Assist problems of the 2018 Acura MDX

Warning lights for collision mitigation system, road departure mitigation, adaptive cruise control. Lane keeping assistance, auto high beam. Features are now disabled causing safety issue. Dealer confirms issues and recommends repairs that have not not been solved by others online. Errors appeared before battery failure in March 2026. Battery was replaced. Common complaint by many online. Need recall to fix.

While driving the car, several warning lights turned on all at once, saying that the following components were disabled: lane keep assist, adaptive cruise control, automatic high beams, and collision mitigation braking system. Not being able to use these features is more dangerous, not to mention that the warning lights associated with their disabling are distracting (making it likely that, if a more serious warning was flashing, it would not be noticed by the driver) and cannot be turned off without an expensive replacement. Yes, the problem was confirmed by a trusted mechanic (the warning lights will not turn off so it's not hard to confirm), who indicated that the radar camera needed to be replaced. No, the component has not been inspected by others. There was no warning of the problem.

The front camera failure. Needs replacement. Camera apparently is used for the acc , lane departure assistance.

Got multiple warnings, systems don't work: collision mitigation system, adaptive cruise control, lane keeping asist, road departure mitigation system. All those additional systems designed for safety are no longer working. The front camera failed, as confirmed by the dealer. Part is available for inspection.

While operating the vehicle, multiple driver-assist warning indicators illuminated on the dashboard, including lkas (lane keeping assist system), acc (adaptive cruise control), and cmbs (collision mitigation braking system). The systems either disengaged or functioned erratically during normal driving conditions. At times, the vehicle failed to maintain lane position, abruptly disengaged adaptive cruise control, or displayed collision alerts when no obstruction was present. Now it is constant. Safety impact: the failure of the lkas, acc, and related systems can cause unexpected loss of vehicle assist functions, leading to abrupt speed changes or compromised lane control, increasing the risk of collision if not promptly corrected.

Lane keep assist, adaptive cruise control, forward collision warning all stopped working and received error codes. Dealership stated camera was faulty and needed to be replaced at my cost. Continued issues with electrical systems where the car alarm will go off intermittently, and vehicle will not lock unless manually locking. Dealership stated Smart control unit needs to also be replaced at my cost. Part number for control unit #38320 was issued by Honda motor company service bulletin 21-055 for their Honda ridgeline. Acura dealer will not honor since part number does not specify Acura. Part issued in service bulletin is 38320-t6z-a11 (Honda ridgeline) part needed to be replaced by Acura is 38320-trx-a11. Other service bulletins related to original issues: 20-015, 19-005, 23-008, and 24-022 and safety recall report 23v-751. Dealership is still placing responsibility of repair of defective parts on car owner.
