Our engine started making a loud knocking noise that was clearly not good. We had a friend who is a mechanic come put it on the computer and he diagnosed that the rocker arm took out some valves or lifters.

Our engine started making a loud knocking noise that was clearly not good. We had a friend who is a mechanic come put it on the computer and he diagnosed that the rocker arm took out some valves or lifters. He looked up the car and found a recall for our make and model (2017 MDX with the 3.5L engine) that matches our exact issue. But the VIN does not appear in the search so our car is not covered by the recall despite it clearly being caused by the defect. I understand that there is an investigation into this that the NHTSA opened and Honda has been pushing for extensions. I was encouraged to add our car to this list to help you all see that the problem is much larger than originally thought. We are in a very tough spot and do not have the $5-10k to replace the engine. If the recall is not expanded soon, our only hope is that we get a goodwill repair. We have requested this, but are waiting to hear back from the dealer. Thank you for looking into this. I’m sure we are not the only people in a tough financial spot being affected by this. We appreciate your efforts to protect consumers!

I reported these issues to Acura corporate and to Jackson Acura, dealership I purchased the vehicle from in February 2024. Beginning in July 2024 the vehicle would stall, de-accelerate then the automatic brake would engage, and the vehicle would go into "N" mode, Neutral and lock up. I was able to press the gas pedal a few times, and the vehicle would come back online and drive. This issue happens about every 100 miles driven. On [XXX] the vehicle suddenly de-accelerated, went into auto brake mode and then shifted into neutral. On this date the vehicle locked up suddenly to an abrupt stop, we were almost impacted in the rear with two other vehicles having to take evasive action to avoid hitting us. My wife and I were lucky not to injured by the sudden brake, or transmission lock up. There were no other issues with the vehicle until this date, other than the stall issue. It seems the system had a sudden catastrophic failure. the car has been maintained with oil changes, new battery and transmission service. The car was shutdown then restarted. All the lights on the dash were on and the vehicle was unable to shift to any gear. The vehicle had to be towed to my home address. I was advised to have the vehicle towed to a dealer for diagnostics at my expense. It is currently at Nalley Acura, Marietta, Ga being diagnosed for the issues. The vehicle has 74,000 miles currently. It was purchased with 57,700 miles from Jacson Acura as a certified Acura used vehicle. The Acura dealer and Acura corporate both stated my VIN # was not included in the recalls. It should be included in the recalls as it has the same issues as other Acura models.

The transmission failed. It is not able to be inspected unless retrieved by the dealer. While driving the vehicle the transmission would disengage. There were no warning lights or failures picked up by the CAN bus. This would happen during normal driving on the highway, potentially leaving the vehicle stranded in the middle of the highway. When issue occurred the transmission would make a whining noise. I was able to replicate the issue with the dealer. I am unaware if the part was inspected. I contacted Acura of America to report the problem. The issue mimicked the reported recall that Acura issue on a portion of MDX of the same year. They offered no assistance to the issue. There were no warning lights or indicators to let me know of a transmission issue.

Ive brought my MDX to the dealership service department 6 times for this issue, my car has been with the service department this last time since Nov 28th consecutively. In September I brought it in because my car would shift to park when the auto start/stop engaged, I would have to hit the brakes, shift back in to drive before I could take off. I was told there were 2 recalls that we remedied at that time. I brought my car back in a couple weeks later because the issue was persisting, I also started to get transmission and blind spot monitoring system alerts in those 2 weeks. I was told by the service department that the recall update wasn't "completed" when I brought it the previous time. The shift to park still was not fixed. At the 3rd time to the service department they replaced my starter. After this was done the issues with the car got worse, the car would give me transmission alerts, emission system alerts, power brake, blind spot, etc. & the "D" for drive on the dash would blink. Park would also blink. On the 4th trip they replaced my shifter assembly. After this the issues with the car further worsened and I would get all of the previously mentioned alerts, then my car would shift to neutral and another alert would pop up saying "pull over and park when safe to do so". Thankfully I was never on the interstate when this happened. I have to coast until I can pull off the road. After turning the car off then back on I was still not able to shift in to gear. I had the car towed to Acura, this (5th trip) time they replaced my transmission computer module. The car did the same thing the day after I picked it up. I had it towed back to them again, this latest trip they replaced my powertrain computer module, it did not fix the issue. My MDX has been at the dealership since Nov 28th because they do not know what to attempt to fix next. Im not being given any recourse. There are class-action lawsuits regarding this issue on the internet, so it is not unique to me

I was driving on the interstate yesterday ([XXX]) and the transmission suddenly downshifted gears and also went to neutral. I managed to pull to the shoulder, but the sudden loss of power could easily have been life threatening at a more crowded time of day or in poor weather. The car was towed to McDaniel Acura in Columbia, SC (I was out of town) and problem confirmed. I also called my regular mechanic (a Honda specialist) and he said this was a known problem and referenced Acura service bulletin [XXX] which says to reload new software. Codes were: Transmission code P0716 Parking Brake System U0401-68 Parking brake warning light on Blind spot warning light on Why hasn't there been a recall on this??? It's a known problem and I could easily have been killed and hurt others. If not a recall, at least at least do something to alert owners so they can get it fixed proactively if they want, as opposed to breaking down on the side of an interstate for hours.

In October I noticed my engine knocking. It has always made a ticking sound so how long it might have knocked before we noticed I don’t know however in October it was clearly noticeable. The first thing I did was check my oil level and it was full. Over the several days it became more noticeable and one morning while driving my check engine light came on and the vehicle lost most(maybe 80%) of it’s power although it did continue running and I managed to make it home and immediately scheduled an appointment with Pecheles Honda to have it looked at. When I started the car the next morning the engine light was off and I drove it to the Honda dealership where I was told I would need a new engine. We regularly had the oil changed using synthetic oil and it never burned one drop of oil so I didn’t have any idea how or why it could have happened because it is very common for issues like this to occur due to low engine oil. Last week I learned of a recall on multiple Honda and Acura vehicles the same year and model as mine due to faulty rod bearings with symptoms exactly like I experienced only to find out that mine is not included in the recall. Right now it is sitting in my yard because I don’t have $10,000 to get the motor replaced. The Honda service manager and their best mechanic were at a loss at how the motor could have went so pre maturely. Something faulty had to have been put in that motor because I took great care of that car and never drove it hard. Before this car we had a 2003 Honda Pilot we owned for nearly 15 years with 300,000 miles on it that never had one issue the whole time we had it and this issue should not happen to 6 year old Acura’s. I wanted to document this issue and hope anyone else going through the same misfortune with these vehicles does the same.

PE25008 · Engine Failure

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.

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.
