POWER TRAIN, VEHICLE SPEED CONTROL
There were several instances where my vehicle either accelerated or decelerated while I was driving. I first noticed the issue about a week after I purchased the car in May 2022. I took it back to Acura of Brookfield, and they said they couldn’t replicate the issue. I also took my car to Acura of Brookfield in September 2023 for the same jerking issue. They charged me for an update, but the issue did not change. I continued noticing the problem over the years, but it happened more frequently in 2025. In May 2025, I was driving down a hill in Brookfield, Wisconsin, when my car jerked aggressively and then accelerated on its own. Throughout the rest of the year, it would either accelerate or decelerate while I was on the highway. On January 20, while I was on my way to the gym, my car jerked and decelerated while I was on the highway. I was able to pick up speed again and continue driving to the gym. When I came back out, my car started, but it would not shift out of park. I had the car towed to Acura of Brookfield, and they said something about the hydraulics inside the transmission being bad, and that they had to replace the entire transmission.

Hello, I am writing to report that my 2017 vehicle is experiencing the same issue that was subject to a recall on the 2016 models. Despite the recall being associated with the 2016 year, my 2017 vehicle is showing identical symptoms and concerns. This raises serious questions about safety, reliability, and whether this issue extends beyond the originally recalled model year. I would like this concern formally documented and request a review of my vehicle to determine whether it qualifies for repair, inspection, or coverage related to the prior recall. Please advise on the next steps and whether this issue has been reported or addressed for 2017 models. Vehicle details: Year: 2017 I appreciate your prompt attention to this matter and look forward to your response. Sincerely, [XXX] If I get killed me or my [XXX] son, you all will be responsible. You made these faulty vehicles. [XXX] I'm have to get a lawyer involved if issues are not addressed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE
Our 2017 Acura MDX has developed a crank rod bearing knock. Fox Acura in Grand Rapids, Michigan, has advised that our vehicle’s VIN is not included in service bulletin 23 036 concerning connecting rod bearing failure, despite evidence that similar failures have occurred in Acura 3.5 liter engines outside the bulletin’s listed VIN range. I intend to submit a safety complaint to the NTSB regarding this issue. Fox Acura has recommended a full engine replacement. I respectfully request that Acura expand the scope of the service bulletin to include our vehicle and provide coverage for the recommended repair.

POWER TRAIN
Since 2020 the transmission does not shift properly from second to third gear. The power drops and the car shutters and makes noise like gear teeth are missing. This does not happen every time though. Sometimes multiple days will pass before the problem arises again. There have been a couple of times where I barely avoided a wreck because of the drop in power and underperformance of the transmission.

ENGINE
On my way home from work one evening, the car started making a loud knocking noise, then the car started losing power, the rpms jumping up and down and the dashboard lit up with warnings of all kinds. The traffic was somewhat heavy and and cars were speeding pass me, brakes screeching, horns blowing and my car steadily losing power. I was afraid, I didn't know what to do. I was trying to find a safe place to pull off the road. It was a traumatic experience as a large truck swerved into the other lane of traffic to avoid hitting me, almost causing an accident. Luckily I made it home safely. I had a mechanic look at it the next day and he said the engine needed to be replaced. Not convinced of the diagnosis, I had the car towed to another mechanic who confirmed the engine would have to be replaced. I had no issues with the car or the mechanics of the car prior to this. I could not for the life of me understand how my 2017 Acura MDX with only 74,000 miles on it, could possibly need a new engine unless it was defective. So I then towed the car to the Acura dealership where they confirmed, the engine needed to be replaced. However, when I asked about the engine recall, I was told my VIN is not included in the recall although it is the same exact issue. Acura did offer a one time goodwill assistance for 25% of the repair costs if performed at Acura. Admission of guilt knowing my car has a defective engine is what that says to me about Acura's offer of 25%! Since the car was useless without a engine, I have since had it repaired by an independent mechanic. I'm very disappointed in Acura.

LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Dear Acura, My MDX is showing many lights on the dashboard (LKAS, ACC, Break System, CMBS, RDM) associates with the code U3000-49 and all those features are deactivated due to the failure mentioned. I was searching on the website for this error and found many Acura MDX oweners experiencing the same issue which apparently the Windshield Lane Departure Camera. Honestly, Acura should take a look into this since this issue is getting worse and those are safety features on the vehicle. Regards,

ENGINE
Engine completely seized due to connecting rod bearing failure. This happened while driving, and I was stuck in traffic for almost an hour due to the vehicle being inoperable. vehicle was unable to be put in neutral due to a special tool being needed. Technicians from a third-party shop and Acura dealership stated this part does not break very often. The Vin does not fall in the parameters for the recall. The issue started the day prior with the engine, sounding like it needed a tuneup. After conducting the tuneup, the engine seized 20 miles after. The engine had to be completely replaced at the owners expense. Accurate did cover 50% of the replacement engine.

My 2017 Acura MDX has an engine failure due to connecting rod bearing seizure in the 3.5L V6 engine. Recall 23V-751 covered model year 2016-2020 Acura MDX vehicles and mine is a 2017. But, my VIN is not in Honda's recall range. The ODI had apparently received 414 reports of connecting rod bearing failures in the 3.5L V6 engine that are outside of 23V-751. There is now an ODI Resume with number PE25008. See the two linked PDF documents below. [XXX] [XXX] The Acura dealer said that this is definitely the same problem they have seen on vehicles under the recall range. In their computer system where it says "Cause" they wrote "Cylinder 6 spun causing the knocking noise. excessive material in oil pan. if under the rod recall, it would need a long block." I have a screenshot of this if you would like it. My service representative at the dealership texted me the following "The engineer from Acura was here today and our District Manager - the engineer said they will not be expanding the recall on the Acura side. Just thought I'd let you know." I have this text message if you would like a screenshot of it. So, it sounds like Acura will not voluntarily expand the recall. This is going to cost me about $12K to fix. Is the NHTSA ODI investigation still ongoing? When will I know if the VIN range will be expanded as I would like to get reimbursed by Acura for these repairs.

SERVICE BRAKES
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.

ENGINE, UNKNOWN OR OTHER
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.

ENGINE
I was driving my vehicle on the highway at 65 MPH when the engine light came on and began blinking- no other issues. I tried to pass a vehicle, and my vehicle would not accelerate, I was less than a mile from work. I called the dealership the same day and was able to take it in. When I called, I explained everything the dealership told me I could either tow it or try to drive it in. I went out to the car later and moved it from one parking lot to another and had no issues and no lights came on alerting something was wrong. Later in the day as I was driving 65 mph again on interstate, just as I was slowing down to get off all of the lights for everything came on and the engine was making a terrible knocking sound. I slowly pulled over and put my hazards on while driving 15/20 mph. I was near the dealership and was able to coast into the repair shop. Was informed the engine needed to be replaced due to a misfire on cylinder 2 and rod knock- most likely rod bearings and crank shaft issue with broken rod. We have an extended warranty so for a used engine found at a salvage yard won't cost much out of pocket with a similar amount of miles. Used engine will have 12K mile warranty/12months. The dealership has the engine- that info can be given upon request.
