Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2017 Acura MDX owners, lightly cleaned up (personal details are redacted by NHTSA).
Brake system, Cruise control, lane keeping system get malfunction erratically (ever since 2022, and has been like this), and one of the two sets of brakes never wears off (More than 100 K mileage now (Oct. 2026) , one set of brake pads still is still have sufficient life and does not seem to require replacement. Additiionally, recently (August 2026) the electronic system has gone very bad, the dashboard automatically restarts, headlight turns on, and trying to engaging something, then turned off automatically, then a new cycle starts, and even I turned off again, the cycle will restart until battery is drained and dead, if I do not lock the car (and I had to replace a new battery that was used for less than 1.5 year. If I lock the car, the car will start the same cycle and will honk, and honk, until the surrounding people had to remove the car.
My 2017 Acura MDX has many issues with both the transmission and electrical. It has an issue shifting between gears, makes a loud sound like metal on wash board, then loses power for 3-5 seconds. I went to put the car in drive and it would not go in drive recently. I've now had to replace the transmission at 79,006 miles. The electrical system lights up when driving telling me my electronic parking brake has been engaged and also that there is emission system issues. My daughter was terrified and crying since i had a loss of power at the same time my dash lit up and I had to get across 5 lanes of traffic to the shoulder of road. The towing company had to remove battery cable to get my electric parking break to release. This is a dangerous and scary automobile
I was stopped, my vehicle brake stopped working after being stopped on a road at a traffic light behind a semi truck. My vehicle crawled slowly forward, it would not stop (like the car wash pace). My brake would not work, I tried putting car in park to stop it moving. It proceeded to ram into the semi in front of me and keep trying to go forward until the light turned green and the semi drove away at that point I was able to drive my car and pull off the road and my brake began to work when I pulled off. It completely stopped working when I was on a busy road and caused the accident. It could have been much worse if I was not stopped already.
This morning I read that you were investigating the automatic braking for certain Honda models. I have had this same thing happen with my 2017 Acura MDX several times over the past few years. I would be driving (not following another car), and my car would suddenly brake and flash "Brake" on the screen, without my doing anything. Both times, I attributed the issue to driving into a bright sun, but I am not sure. It did not cause an accident and it was not a big deal, but the last time (about 3 months ago) I remember braking and being nervous about someone else read ending me...when I tried to accelerate I was unable to do so.
While driving the car started to loose momentum and began stuttering until finally stopping abruptly and applying the electronic braking system. All warning alarms were illuminated on the dash. I was not even able to pull over completely off the road either putting me and my family in danger from not being off the road. Acura dealership service center informed me it was a bad high pressure fuel pump located on the engine block itself. There are recalls for this exact part neginnibg from 2018 on the acura MDX model. My model is a 2017 making me wonder if the recall should include earlier year models of acura mdx.
While driving suddenly all error warnings came up. It included Check Engine Light, Error messages included: Electronic Braking System error, Emission System error. The light indicative of parking P! kept blinking also the (P) came up on the dashboard. Interestingly after some time this all cleared on its own. Then came back again only this time it stayed on. I don't know if this has compromised the safety features of the vehicle including emergency braking (crash avoidance/vehicle proximity)
There is an active recall on the brake calipers and fuel pump for Acura Mdx 2017, and Hondas. My Acura Mdx 2017 has the same issues with a code of p07e4, which is the brake calipers. When looking up the recall of my car, there is no recall on it when inserting the VIN. My car is an Acura Mdx 2017; I do not understand why it is not included in the recall when it should.
The vehicle put emission system and electronic parking brake warning lights on panel, allowed vehicle to be placed in drive "D", then suddenly switched to a flashing "P," stalled in parking lot, and would not allow the vehicle to be changed to any other gear.
Driving in rain and multiple systems failed at once without any reason. Car indicates brake systems, lane assistance, power steering, collision mitigation, stability control, etc all indicate problems. No reason for it to all go out at once.
We were traveling on a three-lane road (center turn lane) in our 2017 Acura MDX going approximately 35 MPH and following the vehicle in front of us at the normal 4-car length distance. The car in front of us signaled for a right turn off the main road and began to slow. I applied our brakes to slow as well. We were still at least 3 car lengths behind when the car in front of us turned off the main road. I moved my foot off the brake to accelerate back to the normal speed. The collision mitigation braking system activated, bringing our vehicle to a sudden stop in traffic. The vehicle that had made the right turn was completely off the main road when our brake system activated. We were rear-ended by a Jeep wrangler traveling at or near the speed limit. Our vehicle was totaled. I want to note that this was not a case of us following too closely or approaching too fast! …
