My 2017 Acura MDX unexpectedly shifts into neutral while I am driving, specifically when slowing down approaching stop signs. When this happens, the vehicle loses power and will not accelerate, creating a dangerous situation in traffic. I have to manually press the Drive button to put the vehicle back into gear while still on the road. This has happened multiple times without warning and no recall exists for this issue. This is a serious safety hazard because the vehicle can lose power in traffic or intersections.

On 11.25.25, my MDX was involved in a multi-car hit and run on highway 101 SB at the Laurel Drive off ramp. The vehicle sustained two points of impact: (1) substantial front/driver side impact (2) rear-passenger side impact. Despite the severity, location of impact and speed of travel at the time of the collision, all airbags deployed except for the driver side curtain airbag. Importantly, at the time of the crash, the Lane Keeping Assist System (LKAS) and associated AcuraWatch driver assist systems were activated. The vehicle’s safety assistance technology was engaged and functioning immediately prior to impact. Considering the above mentioned facts, driver side airbag failing to deploy, raises serious concerns regarding Possible software or signal-processing malfunction or electronic communication between radar/camera systems and the SRS module. The nature and severity of the impact clearly met deployment criteria for the driver side airbag. This failure raises concern that there may be a defect in the SRS system, including but not limited to: Airbag inflator component or propellant issue. Supplemental Restraint System (SRS) crash sensor calibration. SRS control module deployment logic. Crash signal sensors. Event-trigger logic or interconnnect failure. Wiring harness or inflator defect. Whether the system registered steering correction or impact prediction, the failure to deploy increased my risk and resulting injury, as well as compromised the fundamental safety system designed to protect drivers in front-impact crashes.

2017 Acura Mdx. Earlier this year I suspected something was wrong with the car so we took it to Acura in weir canyon to get it checked out. They figured it was the throttle body so they replaced it and then about 2 weeks later the engine had a catastrophic failure. I was driving the car coming out of the freeway and right before I turned right the engine made a huge noise. We tried asking Acura for goodwill assistance but they did not offer anything at all because I bought the car used. I always took the car for its maintenance while the time I've had it. Acura then quoted me for around an 8 thousand dollar repair and then took it to a mechanic and they said its better to get the whole engine replaced at that point and so I did. I've always had Honda cars my whole life and they have been nothing but good but this was something different. I saw that there was a lawsuit going on and a lot of people has had the same problem with there engine specifically the connecting rod bearing which is the problem my car had.

Hi, I have a 2017 Acura MDX. My Transmission Shifts to Neutral Unexpectedly. It happens when I'm driving. Most of the time it shifts back to Drive. Therefore, it never bothered me, it happened since I bough the car. It didn't happen often so I didn't think anything of it. However, lately it started to happen more often. Now when it shifts to Neutral it doesn't want to shift back do Drive. My concern happened when I was on a highway driving in a middle lane. I had to pull over and when it shifts to Neutral. When it shifts to Neutral you can't add gas and the vehicle starts slowing down. I received warning on my dashboard ((P))! - Electric Parking Brake Problem and (transition picture)- Emission System Problem came on. I turned the car off and then on. After, I turned on and Press D or R the car doesn't want to go forward or reverse. I have to turn the car off for about 15 min and then when I turn the car on and press Drive it drives without a problem. Recently, it started to happen more often. I happened to me today. I was on 2 line road on a left lane. My car stated to slow down. I was lucky nobody was on right lane, so I was able to change lanes and then I had to pull over and turn the car off. I waited 5 min turned the car on and it drove. I'm scared that I might not be as lucky as I was and get in an accident when the transmission shifts to neutral. My VIN is not on recall but there is a recall on 2016-2020 Acura MDX with same problem. 16V640/KC2 recall. I already contacted my dealer with no luck. They told me to contact Acura. I made a case # [XXX] with Acura. I was told they can't do anything and the bounce the ball again this time to NHTSA. Here I'm looking for help. My dealer found a Par 573 Safety Recall Report on NHTSA site. I love the car. I was hoping you can help me with this problem or maybe you can tell me who can help me.

Phone: [XXX] VIN: [XXX] Vehicle : 2017 Acura MDX Dealership: DCH Montclair Acura, Bloomfield NJ 07103 Warranty: Extended Warranty Active Previous Case No: [XXX] Subject : Formal Complaint-Dashboard Errors and Inadequate Warranty Support Dear Acura Client Relations, I am writing to formally file a complaint regarding ongoing dashboard error messages in my 2017 Acura MDX and the poor handling of the situation by both your Customer service and DCH Montclair Acura in Bloomfield, NJ. The errors occur intermittently during my work commute. When I contacted customer service, I was told by Case Manager (Andrew) on [XXX] @ [XXX] pm that nothing could be done unless I brought the vehicle in while the warning lights were actively on. This is unrealistic and dismissive. It is not always possible or safe to divert immediately to a dealership and I do not believe that Acura expects its customers to drive around hoping a warning light stays on long enough to be seen by a technician. I understand that modern vehicles like the MDX store fault codes even after warning lights disappear. That Is the purpose of diagnostic equipment. Denying a warranty repair based on whether a technician witnessed an error live undermines the value of the extended warranty i paid for raises serious concerns about safety and accountability. I plan to visit DCH Montclair and attempt to schedule an appointment in advance. I expect a full diagnostic scan to be performed, with no fee applied unless the issue is clearly outside of warranty. I am requesting the following: A complete diagnostic of stored fault codes, regardless of whether the dashboard errors are active at the time of service. Full written documentation of the findings and action taken A clear explanation of any charges and why they would apply under my extended warranty. If this matter is not resolved appropriately, I will escalate it through the BBB INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Opened Aug 20, 2025 · No close date supplied
Status: open (inferred from source dates) · Engine
The Office of Defects Investigation (ODI) has received 414 reports of connecting rod bearing failures in the 3.5L V6 engine used in the following vehicles: Model Years (MY) 2018-2020 Acura TLX, MY2016-2020 Acura MDX, MY2016-2020 Honda Pilot, MY2018-2020 Honda Odyssey, and MY2017-2019 Honda Ridgeline. The subject engine failures were analyzed as part of a Recall Query (RQ24013). It was determined that these engine failures are outside the scope of Honda Recall 23V-751. Further, evidence gathered in conjunction with RQ24013 does not suggest this failure is caused by the same crankshaft manufacturing defect that is addressed by Honda in Recall 23V-751. Based on analysis of data from RQ24013, NHTSA has closed that investigation. The significant number of reports of engine failure in vehicles outside the scope of RQ24013 presents a potential safety risk that warrants further investigation. ODI is opening this Preliminary Evaluation (PE) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update.

RQ24013 · Engine Failure
Opened Nov 8, 2024 · Closed Aug 20, 2025
Status: closed (inferred from source dates) · Engine
On November 8, 2024, the Office of Defects Investigation (ODI) opened Recall Query RQ24013 to assess the scope of Honda recall 23V-751 after receiving complaints that alleged connecting rod bearing failures in vehicles that were not within the scope of recall 23V-751. In November 2023, Honda recalled 248,999 various Model Year (MY)2016–2020 Honda and Acura vehicles equipped with the 3.5L V6 engine. Honda recalled these vehicles due to a crankshaft manufacturing defect that caused premature connecting rod bearing wear and engine seizure. While the out-of-scope failures involved in these complaints appear to have a very similar failure mechanism as the recalled engines, a thorough analysis of all available data from Honda has not indicated that the same manufacturing defect exists in the out-of-scope engines as the engines recalled by 23V-751. Based on this analysis ODI has determined that Honda has properly defined the scope of recall 23V-751. Consequently, ODI will close this RQ investigation. NHTSA will continue to investigate these complaints of engine failure as part of a new Preliminary Evaluation Investigation (PE25008). The Agency reserves the right to take additional action if warranted by new circumstances.
