Warnings Problems of Acura MDX - part 2

Forward collision mitigation braking randomly activates and slams on the brakes despite no cars/obstacles/items in front of it. I have luckily not been rear-ended, but I've had several close calls when driving in traffic (car noses dipping behind me). The dealership has so far been unable to replicate this issue and stated that unless they can replicate there is nothing they can/will do to fix the issue.

The auto engine idle stop on my 2016 Acura Mdx has left me in precarious situations at stop signs and/or traffic lights at least twice before the recall notification I received in the mail a couple of weeks ago. The engine turned off as designed but then would not turn back on like it should without a delay. The worst incident was when my teenage daughters were in the car with me! after receiving the recall notice recently and taking the vehicle into the dealership within days of the notification, my “software update fix” by the dealership (napleton Acura in west palm beach) completely disabled my auto engine idle stop! after calling the service rep I dealt with later that day and telling him about it, I was told the software update made the “turn-off” feature more specific and mine didn’t meet the parameters! my engine was at normal operating temperature, my air conditioner was not on and I stopped at at least 12 lights on the way home with no engine stop. That was a week ago and still no engine idle stop has taken place! I’m a pilot and don’t appreciate being talked down to by a supposed “racing champion” named zeke that feels the need to advertise his prior win on his service uniform! not only that, but now my safety related “object approaching” notification for front driving and “rear warning” for close objects during parking/reversing are now non-existent! I paid extra for these safety related options and I’m not happy that they’ve been disabled because of the “software update!” how do I become part of the class action lawsuit against Acura/Honda?.

2018 purchased a little more than a month ago as a certified used Acura. Twice now we have been overridden by the automatic forward collision detecting something in front when nothing was there. Once on the freeway went from 70mph to 15 quickly and almost got rear ended. Just now on city street car stopped in the middle of intersection while turning left and overrides driver pressing gas pedal in both cases. Makes us scared to drive SUV further and we have turned off that feature to see if it still happens.

My car routinely sends a warning alert that there is an approaching object. It happens more frequently, when the temperature is hot, and it happens mostly when I am stopped at a traffic light. Occasionally, the alerts continue as I'm moving, which is really distracting, but even sitting at a traffic light is distracting and creating a safety issue. I listed yesterday's date, but this happens nearly every day that I drive this vehicle.

During driving, collision mitigation braking system (cmbs) will activate and "brake" light will blink, indicating that you should apply brakes. This happened multiple times. Finally the cmbs warning light came on permanently. I took my car to Acura dealership for repairs. They informed me that it was a software issue and update of the software should resolve this problem.

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.

Observation 1: lane-keeping assistance is unreliable and the results of its operation are highly variable. In optimum conditions (daylight, wide lanes which are clearly marked; good contract between lane markings & pavement; no more than very gentle, wide-radius curves), this feature will do one of three things when the vehicle starts to drift from the middle of the lane: (1) the feature will gently steer the vehicle back to the desired position, (2) the feature will exhibit a warning by vibrating the steering wheel and allow the vehicle to change lanes or (3) fail and do nothing -- without any warning whatsoever. One never knows how the car will react but it certainly cannot be trusted. Observation 2: when driving in light traffic or no traffic conditions the vehicle will occasionally brake aggressively. This was observed to occur on multiple occasions. Two situational examples which have been observed several times: (1) four lane roadway inside city limits; speed: 40mph; I was gently braking to stop behind a vehicle stopped at a traffic light; car applied brakes rapidly nearly causing a rear-end crash as the vehicle behind me did not anticipate the Acura's action. (judging from the hand signal I received I believe the driver of the vehicle behind me though I was administering a "brake test" -- a common precursor to "road rage. ") (2) driving on a two lane country road at 50-55mph; no other traffic within hundreds of feet in any direction; vehicle brakes rapidly for no apparent reason; my attempt to accelerate and over-ride the "safety feature" was unsuccessful -- eventually the Acura stopped this action and I was able to resume desired speed. Important to note: at no time during these incidents did braking occur to avoid a crash or minimize damage. These were uncommanded operations that actually increased the probability of a crash. These events occurred between 11/21 and 03/22.
