When at a complete stop at a stop light or stop sign and ready to press the gas to accelerate, there’s a delay for the car to even start moving. It doesn’t want to go when pressed on. Which can cause the person behind me to hit the back of the car. It nearly came to that. There’s sudden fast movement when accelerating to get the car to move forward. It’s been happening numerous times where the gas pedal isn’t recognizing the acceleration part. I’ve read plenty forums about this issue with this vehicle and still not enough complaints for a recall? Can we look into this as this is a safety issue. The car won’t accelerate when you want it to.
This is a complaint about the defective TPMS components in this vehicle. I sent a copy to Acura and Honda Client Relations and to the Dealer (Montano Acura). [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Electric Parking Brake light and Emissions System light popped up at the same time. Replaced the battery the lights gone immediately for weeks, but reappears again. Disconnected the battery and reconnected it the lights gone for one month and came back again. Search online there are a lot of similar situations. The dealer replaced parts but the issue stated. There must be some malfunctions of the ECU or something else.

Bought vehicle new in 2018. Starting in 2020, brought car to dealership complaining that car, at times, did not accelerate when prompted. Vehicle pauses, then lurches forward. Very dangerous when making left turns and when merging with traffic. My wife (who used to be primary driver of this vehicle), refused to continue to drive it ...and neither I nor my wife would allow our now age 21 daughter to drive it. So this vehicle (as unsafe as it was) became my back and forth to work vehicle. Vehicle was brought to the dealership on at least 4 or 5 times with this complaint - from 2020 through 2024...One time it was at dealership for almost 2 weeks Dealership would never fully admit to the issue - often times one service person, through test driving would notice the issue, only to then be told it was "normal driving" of this vehicle. On a regular basis, car would stop (pause) "in the face of oncoming traffic - my heart would skip a beat, only for the car to then resume accelerating On many occasions, I discussed with service team - always to be told that there were no known issues Fast forward to 2024 - when Acura notified me of a Recall regarding the Fuel Pump....I quickly scheduled an appointment, brought the car in this past week and had the Recall done. Speaking with the Serviceperson when checking the car in, I brought up the past issues that I have had and asked if this Recall was the likely reason.....the service person - without hesitation said "absolutely"......I then asked him, so was "Acura lying to me ll these past visits".....his response was "sounds like it to me" Since getting the car back - the hesitation has stopped. I have paperwork from all my previous visits - with responses from their technicians I am certain there was consumer fraud conducted by the dealership I bought and serviced this vehicle from (Open Road Acura - Wayne NJ). Add to it , the inconveniences I experienced and the fear that my wife and daughter had of the vehicle.
Contacted dealer to schedule a recall repair appointment in July 2024. The appointment was scheduled for November 11th. I showed up on November 11th and was told my appointment was not scheduled until December 11th. It’s been more than 4 months since I contacted them and the repair hasn’t been done.
I have been trying to get the two recalls fixed for several months with the dealership telling me they don't have the parts and they would contact me when they get the parts in. No one contacts me, I call to find out if they have received parts. Recall, 23V-858 and 23V-751.

My 2018 Acura MDX received an Auto Engine Software update a couple months ago. I took it in "Acura of Johnston" in Iowa due to a recall notice I received that indicated engine could stall when trying to accelerate or may not restart. After the the software update I was told this should fix the problem and they would only replace the mechanical parts if the software failed; Starter Motor Assembly along with the Power Relay Assembly. I left the dealership and later that day the message "Auto Engine Idle Stop System Problem" flashed periodically. I called the dealership and spoke to the Service Department. He explained that wasnt a problem, as it is probably due to outside temperature and the update now has 13 different variables and should be okay. (I didn't buy it) he told me to contact them if it continued. In the past 2 weeks starting towards the end of December 2023 the "Auto Engine Idle Stop System Problem" message flashes several times during driving with a chine. I called the dealership and they tried to explain away it was due to temperature. I pushed back and reminded him what he told me previously. He then put me on hold and came back and said to bring the car in. I did contact Acura customer care and explained what happened and told them I read the original technician guide that stated if the software didn't take they would need to replace the parts. I asked this is covered correct? The representative said no because my care has a "Rebuild Title" and it would be at your cost. I reminded them that their recall stated this as a Safety Issue. She stated they were only extending the warranty to non "Rebuild Title Owners". I again asked, "Despite this being a safety recall by your own company"? She said yes and parts to fix would be my expense. My VIN is [XXX] and has other recalls outstanding and when I asked about those I wasn't re-assured those would be covered INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This is my first luxury car. Ever since I bought the car in 2019, I noticed that sometimes when I press on the gas pedal, it takes a little time for the car to move. I just assumed it was normal. Never owned an Acura before. Two weeks ago and a week ago, I also got into a car accident. The first time was when I was entering the freeway. I see the cars on the freeway coming from my left side. They were far enough form me enter the freeway safely. I pressed the gas pedal to speed up so I could enter the freeway. I pressed on the gas pedal. Nothing happens. The car didn't respond. I pressed again and this time it moved. By the time my car moved and pick up speed, the oncoming cars were right behind my left side. I had to brake and moved to the right side to avoid an accident. The 2nd time, I was at a stop sign. I pressed the gas pedal. Again, the accelerator did not kick in. The car behind me honked at me. It took a couple of seconds for my car to pick up its speed.

3PE25008 · 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.

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. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.

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.
