2020 Acura MDX driver assistance problems

Filed Sep 13, 2026 · Driver assistance · CA

LKAS, forward collision, high beam all alerts are going off and have been told it's a camera system that gets over heated. This is not a easy fix and needs to be recalled to clear up the codes and alerts.

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 replace the system.

While driving on a residential street under normal daylight conditions, the forward collision warning and automatic emergency braking system failed without warning. A dashboard message appeared instructing me to clean the windshield and stating that collision avoidance services were unavailable. The windshield was clean and unobstructed. There was no precipitation, glare, or debris. The failure occurred while the vehicle was in motion. I had no indication of whether the vehicle was safe to continue driving or whether I should stop immediately, and no way to know whether the fault was limited to the camera or whether other systems were affected. There was no prior warning, no gradual degradation, and no fault indication before this event. I purchased this vehicle in part for its advanced driver assistance systems and rely on forward collision prevention in daily driving. That protection is now unavailable, and I am driving without a crash avoidance system I was sold and expected to have. I took the vehicle to an authorized dealer for diagnosis. The dealer determined that the forward facing camera module must be replaced and recalibrated, and quoted $2,700. No recall or technical service bulletin was identified. I believe this constitutes a safety defect. A primary crash avoidance system failed spontaneously under normal operating conditions on a vehicle marketed on its safety technology. The repair cost is also high enough that many owners will defer or decline it, leaving vehicles on public roads with disabled collision avoidance. I request that the federal safety agency investigate the failure rate of this camera module and consider a safety recall.

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 happening way to often way too soon. my MDX does not even have 70k on it! after doing some research between Facebook, Reddit & many other Acura/Honda forums this appears to be all too common. when that camera shits the bed you lose many of the main safety features that may have brought you to purchase that vehicle. My local Acura dealer in Wilmington, NC told me he is replacing this part once a month and none of them are under warranty I'm not sure why he shared that with me but he did. that is an alarming number considering where i live and how few MDX's there probably are in my area. Where i live everyone drives either a full size pickup or suv and theyre all American brands. the dealer wants $1800 for the repair. I'm getting it done because i have the money to do it but I am not happy at all. normal wear and tear repairs i get, this one however i have a major issue with it. many people are not having the repair done because the car is driveable. any help with this would be greatly appreciated & thank you for your time.

My cruise control, automatic lane changing indicator light indicator, brake indicator light, high beam light indicator lights all keep coming off and on. Researching it on YouTube states that it’s the camera on my windshield getting too hot and it’s a known issue. It’s $1800 To fix but others have stated they get fixed and it doesn’t resolve the problem. Asking for your help.

Faulty forward facing camera affixed internally on windshield. Adaptive Cruise Control will not function. Lane Keeping Assist will not function. Collision Mitigation Braking may be unavailable. Vehicle detects oncoming traffic in opposing lane as a potential collision, causing braking system to engage and causing a risk of a collision or being struck from the rear despite no vehicle ahead except on the opposite side of the road. Acura can not find anything wrong with the vehicle. Recently all warning lights for high beams, braking system, LKAS, road departure, front end collision, etc flash on vehicle. Multiple people with Acura and Honda vehicles have reported the same issue with the front windshield sensor camera, yet no recall, instead they have paid thousands to replace a faulty camera system. Acura quoted $2000 for replacement of camera. Vehicle operationally runs fine. Why has nothing been done despite numerous, repetitive issues with this safety hazard?

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 would’ve caused that to occur.

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 online report identical problems without solutions. Please advise RE next steps for how to resolve.
