   Multiple errors Lane departure and advanced driver support, ACC LKAS, auto high beam, and braking system. Looking into this more i see lots of people with the same issue failing front facing camera and not a cheap fix. Is there any current investigations into this problem or a software upgrade? I clear the errors and they come back once car is turned off and back on. If no fix to the current system there should be a way to disable LKAS and ACC without spending $2000 to…

   Good morning, Out of nowhere my dashboard lit up after 5+ years of having no issues with the vehicle. I believe there are a total of 5 safety features that are linked to the ADAS camera in this MDX but i am not 100%, it may be 4 safety features. I am not here to whine about a repair on a 6 year old vehicle but this particular issue has become extremely common with this vehicle. I believe (along with all the other owners) that the ADAS issue with certain year Acura & Honda is…

   I was pulling up to our house to park in the open garage as I typically do and was in the driveway with my foot lifted off the gas pedal to allow the car to coast forward slowly. The car hesitated for a moment before it lunged/accelerated on its own with such force I had to slam on my brakes to avoid the car hitting the wall of our house. I did not have cruise control on. Took the car to Acura dealership for a multi-point inspection and they found nothing out of order that…

   Add Auto High Beam problem to the above Adaptive cruise control, lane keeping assist, and collision mitigation. Suddenly got several warning popups and persistent warning lights on related to the identified issues. We just replaced the battery a few months ago, and didn't have any of these problems until this week. Now, it happens every time we start the vehicle. We did the Recall software upgrade. I suspect these problems are related to that software upgrade. Many people…

    I was driving on a normal sunny day when every light on my dashboard came on. I initially panicked thinking my car was going to shutoff while I was driving it. This is in conjunction with the car stalling out when the auto shutoff feature malfunctions. After researching the issue, I realized the safety camera was no longer working and a major concern. A malfunctioning front camera can prevent the vehicle from automatically braking or maintaining lanes, hence increasing the…

    There was a couple times where the car stalled at a red light. Also, there are a lot of times when I press the push to start, it will not start, advising me to place the key fob near the push to start. I find this to be dangerous when driving and very annoying when attempting to start and it doesn't start.
