Safety Recall# AOT 2014-20 MDX REAR SUBFRAME REPAIR SAFETY RECALL June 2026 we were made aware that our 2017 Acura MDX SH – AWD had a recall for the rear subframe Safety repair. We immediately contacted Acura Joe Rizza Orland Park, Illinois at the time they said they did not have the Safety recall parts available for the rear subframe but they were on order so they scheduled us to bring the vehicle in on July 1, 2026 to complete the safety recall. invoice included. Just prior to this in May 2026 we were experiencing safety issues with our vehicle, vibrating very severely and pulling when we brought it in they told us it was the drive propeller shaft which, as you will see in the enclosed documents that when the rear subframe prematurely rusts it causes key suspension problems, especially with the drivetrain and propeller shaft . As this was a safety issue, and we felt very concerned about this because the car was NOT safe to drive. We had it repaired prior to receiving this safety recall soon after rear subframe which all makes vehicle unsafe. There’s direct correlation that safety recall the premature rust on the rear subframe which caused structural integrity to degrade and caused severe vibration and pulling on our propeller shaft. Due to the severity and safety as we felt very concerned for our safety with this severe vibration we Paid to have the propeller shaft replaced, then found out a couple of weeks later that the actual rear subframe that has a direct correlation to the propeller shaft get recalled for safety issues. Our vehicle vehicle is a certified vehicle always serviced at Acura dealerships as shown on a car fax .Due to these Safety reasons and the paperwork provided along with the invoices we are asking for a refund in the amount that we paid in total $1313.37 for repair of the propeller shaft which the safety recall the rear subframe caused it to misalign cause abnormal noises severe vibrations SEVERE safety issues for Our family vehicle.

The forward facing camera in the windshield went out causing all these systems to stop working and dash light up like a christmas tree. I cant even use normal cruise control. Dealer wants $1700 to replace it. From what I am reading online this is a very common problem and Acura even superseeded the part. Was that due to failures? I have yet to get this repaired as it is so expensive but i would really like these safety features. 36160-TZ6-A36

FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: WARNING, ELECTRICAL SYSTEM
Various warning lights appear randomly for collision system, lane departure system and brake system and the radio power glitches on/off while driving on highway. I tested the battery and it's good. At one point I was just about to enter a car wash and the radio power glitched off and then a transmission warning appeared and the car shifted to N and I couldn't shift to Drive. I pushed the P button and the dash just showed a blinking P with the transmission warning. With a whole line of cars behind me for the car wash I was in a panic of course. I turned the car off for about a minute and restarted and was able to get it back to normal but had this issue happened while driving then It would've been dangerous.

My 2016 Acura Max sha awd has 124 k on it and the other day I was driving down the road and my engine light went on than I lost power down to 20 mph and heard a knocking noise from the engine like the rod bearing broke or something I’ve noticed the recall on the engine for some Acura 2016-2025 3.5v6 engines but Acura is saying my model car was not in the recall list which I can’t understand why if it has the same engine 3.5 v6 with the same rod barring issue as the ones on the list being recalled . The issue is with all 2016-2025 Acura Mdx models that have the 3.5 v6 in it .

On June 9, 2026, my 2025 Acura MDX, with only 9,139 miles, stalled at a red traffic light after the Auto Idle Stop feature activated. The engine would not restart, leaving the vehicle disabled in an active traffic lane. I was unable to shift the vehicle out of Park and was stranded for approximately 5 to 10 minutes with my two young children in the back seat. The dashboard instructed me to fully depress the brake pedal and press the ENGINE START/STOP button to restart the vehicle, but repeatedly following those instructions did not restart the engine. There were no warning lights or other symptoms before the incident. I feared another vehicle would rear-end us because I could not move the vehicle out of the travel lane. After multiple attempts to turn the vehicle off and back on, it eventually restarted, allowing me to drive home. The vehicle was towed to the Acura dealership on June 10, 2026. The dealership inspected the vehicle, diagnosed a failed starter, and told me the failure was caused by the Auto Idle Stop feature. The starter was replaced, and I was instructed to disable the Auto Idle Stop feature every time I start the vehicle to help prevent the problem from happening again. The dealership has records of the repair, and the vehicle is available for inspection upon request.

Idle stop not functioning properly. Will get to a stop, and numerous times it will not start back up until you put it in park and restart it several times. Sometimes, it will not start on the 1st try from a cold start, or the starter will grind really slow. We have taken this to Acura several times, and they tell us it is a known problem, but just to turn the idle stop off each time.

The malfunction was both rear drains from the sunroof were clogged and possibly kinked. The dealership might still have the components but did not give us access to them. The clog caused the water to enter the vehicle and accumulate. In addition to wet carpeting, an electrical component shorted and failed damaging the Infotainment system. If this had happened during vehicle operation with water moving around, electrical systems could suddenly fail while driving. The vehicle was inspected by the insurance adjustor but was deemed a maintenance issue even though there exist no maintenance instructions or dealership directives for maintenance or inspections. Owner maintenance would not be possible as special tools would be needed without which damage to the drain lines might occur. There was no warning, messaging, or instructions that maintenance was necessary for this item or that it could fail. The first sign was the sound of sloshing water in the vehicle during driving and the failure of the infotainment system. As a remedy, the dealership insisted on replacing the drain lines rather than cleaning them out, which implies that either the dealership was creating extra work for themselves or the drain line could not easily be cleaned.

ELECTRICAL SYSTEM, POWER TRAIN
Monday, June 30th, 2025, while driving on highway trip out of state, the vehicle made severe explosion noise, and sounded like I was dragging something metal under the vehicle for approx 30 seconds. After slowing the vehicle, I confirmed there was nothing under the car and the car seemed to be driving fine. There was zero warning light displaying any type of part failure or warning light addressing anything needed attention. In hindsight, I realize that this is when the transmission transfer case malfunctioned. Entire time since I've had the brand new, premium vehicle the car has had routine, healthy maintence from the dealership and also Christian Brothers Automotive when the dealership service center was under construction. At no point, did the dealership bring this issue to my attention, despite a few multipoint inspections. Once my vehicle was out of warranty, the dealership brought the internal malfunction of the transmission transfer case to my knowledge on June 1, 2026. I am a high mileage driver, and this part malfunctioned (unbeknownst to me) while I was still under warranty, however without the warning light, I was ignorant to what actually occurred. Local acura dealership has briefly commented on this, suggesting we file a good will claim. I am reporting this, because I believe this part needs to be RECALLED. No one needs to deal with an internal part malfunction on a brand new vehicle 50-60k miles in. I have had the dealership, and Christian Brothers automotive both, look at the issue once it was brought to my attention, to confirm it is indeed no longer an AWD vehicle without the 13k repair. I am grateful that I was in a place that was flat, and not in need of the AWD when it went out, it was a very distrubing and distracting situation when it occurred, and with my living conditions I don't used AWD but a few times a year. Glad no one was injured when the part failed, it could have seriously ended differently if there was traffic around.

I was driving on the highway. All of a sudden, my engine started making knocking noises. Shortly after that, the car started to lose power, and immediately the low engine oil light came on. I pulled over immediately to check the engine oil level. Oil level was normal. I restarted the car, but the mechanical knocking noise was evident and did not sound right. Towed the car to the closest Acura Dealership. Diagnostics states that engine has ceased and would not crank. Replacements engine is required and would costs approx. $4200. Acura has a recall on some 2016-2020 MDX for similar engine issues, but my VIN did not qualified. The symptoms i exprienced is very similar to what was described in the recall. Acura representative denied any goodwill support/help.

The subject 2019 Acura MDX model includes the tech package which adds several safety features that function through a windshield mounted camara/radar. The system has malfunctioned and none of the safety features are working. The dash displays the following messages: Collision Mitigation System Problem Adaptive Cruise Control Problem Lane Keeping Asist Problem Road Departure Mitigation System Problem automatic headlight system problem At the bottom of the dash, I see Brake System, Crash Warning and Lane Departure lights on as well. Acura is charging $2,319 to replace this unit in addition to a $270 diagnostic fee. This issue is widely reported as a significant issue in several model years for the MDX and should be part of a safety recall. The Acura technician acknowledged this issue is common. I should add this is the second major electronic issue with this MDX within the last several months. The prior issue was multiple system failure warnings that Acura determined were caused by a faulty wiring harness at a $1,604 cost, plus a $255 diagnostic fee. Please note I am the original owner of the vehicle and it has never been in a collision. Additionally, the system has recently mistakenly activated the brakes at very low speed and warned against collisions with other vehicles traveling in the opposite direction while on a curve.

Noticed fluid was leaking from bottom of car. Took to dealership and they found the transmission output shaft was twisted leading to destruction of transmission seals leading to fluid leak. They recommend full replacement of the transmission and transfer case. It appears NHTSA is already investing this known problem for the 2022 mdx where the transfer case fails and the vehicle loses its AWD function and becomes a FWD car.
