The fuel delivery system, specifically the fuel pump, has malfunctioned. This vehicle is subject to a fuel pump safety recall, which was reportedly repaired in 2022; however, the vehicle continues to experience the same failure symptoms and is available for inspection upon request. The vehicle has stalled multiple times at highway speeds, resulting in sudden loss of power while driving and creating an immediate risk of collision with surrounding traffic. My family was in the vehicle during these incidents, significantly increasing the risk of serious injury or death. The problem has been reproduced multiple times, including after the vehicle was taken to an authorized Acura dealership. During the most recent visit, diagnostic trouble codes were cleared, but the recalled fuel pump was not repaired or replaced. After being released by the dealership, the vehicle stalled again under similar driving conditions. The vehicle was inspected by the dealership, but no corrective repair was performed beyond clearing codes. The manufacturer has not yet properly remedied the recurring safety defect. Prior to stalling, the vehicle exhibited intermittent hesitation, loss of power, and engine shutdown. Warning indicators and fault codes were present at times and were cleared by the dealership without resolving the underlying issue. These symptoms have continued intermittently since the recall repair. This appears to be a failure to properly diagnose and correct a known safety defect, resulting in repeated dangerous highway stalls and placing occupants at serious risk.

Hi, I have had a couple instances where the engine revved up between gears. Both times, I remember it happening rather soon after starting off from a stop sign. I didn't pay it much mind, but noted it. Just today, I asked my wife ([XXX]) whether she had noticed anything with the car. I purposely didn't ask any leading questions. She said a few times it would jump instead of smoothly going to the next gear. In Seaside, OR, I started to pull out onto [XXX], planning to take a right and head south bound. There was a Southbound car approaching from the North, but I had plenty of time to pull out and get up to speed. Immediately after starting out, the car popped into neutral and the RPMs raced. I already had some momentum and was on the highway, so I couldn't brake, and because it went into neutral, I hadn't finalized my turn so I was still pointing SE. As the car quickly approached, all I could do was use what little momentum I had and continue into the Northbound lane so the oncoming car could pass. Because of the slight slope to the Northbound shoulder, I was able to slowly come to a stop. I put the car in Park, turned it off, then back on, and everything came back to normal. I cannot begin to express how scared I was. I have lost brakes before in a car, but I know to use the emergency brake. I was completely dumbfounded as to how to react. Had there been oncoming traffic, it would have been an awful accident. Why is there no recall on this? I researched on Google and found a recall on 2015 Acura TLX 6-cylinder transmission due to a bad wiring harness on their 9-Speed transmission. I know mine is an 8-speed, but would it not use the same wiring harness with slight modifications? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on the freeway/highway my vehicle went into limp mode and shifted into neutral. My vehicle would not allow me to shift gears and the car would not let me accelerate anymore. I had to think quickly and move out from upcoming traffic. With little speed I had on my vehicle I could only shut down the car and wait for a tow truck. This happened to me twice in 2020 and the mechanics could not find any issue or replicate what had happened. They said this was a software issue. I was still scared to drive my car thinking this would happen again. Then 2 years after ( 2024) again this happened and it was when I was on the freeway. Luckily I was on the left side and was able to stop on the shoulder but stressing out and still traumatized from what occurred 2 years ago. I took it to the dealer and same thing they could not replicate the issue and did re programmed the software. I believe this car is not safe to drive at all knowing this can happen again and again at random times. The attached document is what the dealer gave me stating this remedy was done to the vehicle. This need to be investigated.

The transmission is slow, hesitant and jerky in models with the v6 engine. I almost got into a major car crash due to the transmission’s very hesitant behavior. Other owners have experienced this slow and clunky transmission behavior, after looking in many online forums. The transmission has been way since the vehicle first came out but Honda still has not addressed the issue with the 9 speed transmission. This poses a huge safety risk to me and all other owners.

I took my car to an Acura dealer because there was a noticeable increase in engine noise upon starting and at lower engine rpms. The dealer identified that the problem was related to a recall - NHTSA # 23v-751. He also informed me that it may be 3-4 months before Acura is ready ro rectify this problem. The problem has serious consequences and I would like Acura to rectify it much sooner.

I recently got my rotors replaced and the car stutter while braking. Also, this happened before I replaced rotors.. the transmission is slow and won't shift to merge highways. I don't know if its the transmission or the brake lines.. I guess it's the transmission trying to drop gears for engine braking and it starts stuttering.

Upon braking, when coming to a full stop, the transmission (ZF 9-speed automatic) makes a very hard downshift into 1st gear and causes the car to lurch forward. This issue appears to be worsening over time. The car is becoming more and more difficult and dangerous to drive due to this issue. The car was very recently brought into an Acura dealership (DCH Montclair Acura) to address this issue. They replaced the transmission fluid and conducted a general software update, but this issue continues to persist as before.

My car shifts itself into neutral automatically at times while I am driving. It has even happened on the interstate. When this happens it also flashes lots of warning signals on the dash and will be stalled for 4-5 minutes, engine will not shut down, just cannot shift into reverse or drive. The Acura dealership had it all day and they were stumped so they did a software update. I have read this exact problem has happened with other Acura's this same year and model and it was crimped wiring harness of the transmission.

First item: vehicle keeps shutting off during idle while parked or while brake is depressed. It has happened multiple times. I've done some research and see there are several sites indicating issues with the fuel pump and vehicle stalling. Acura says there are no current recalls. I'm not the only person this is happening to. Second issue: vehicle has gone into neutral on its own while driving. At first I thought maybe I hit the neutral button by mistake and didn't think of anything but then the most recent was coming out if a gas station and pulled up to a stop sign and it went into neutral. I just bought this car on June 1st.

I was merging on to the freeway going about 60mph, with traffic right behind me. Car started decelerated and the dash board lit up. A car behind me had to swerve to avoid hitting me. I put on my hazard lights and tried to move to the shoulder the car was only going about 5mph at the time. I turned the car off and restarted to see if it would move, but it was still going about 5mph. After doing this a couple of times I was able to get the car the move at about 20 mph. The dash board is still lit up.

While driving at 60 mph in left lane of highway, without warning, the vehicle slowed and lost all acceleration and slowed, and then a series of warnings lit up on the screen including: electronic parking brake error, a transmission warning pertaining to the ZF 9 speed transmission that demanded driver to pull over to the side to avoid major damage, and emissions failure warning. Then numerous other warnings displayed indicating collision warning system issues, and warnings that other driver safety systems had disengaged or failed. The transmission automatically switched to neutral (which I could only figure out 10 seconds later) as the accelerator would rev the engine but provide no motive force, making changing lanes across 3 lanes of traffic on a busy highway very dangerous as my car decelerated relatively quickly to fast moving highway traffic. After I pulled over and stopped the car, I tried turning off the car and restarting the car, and the transmission error and emissions system error was immediately displayed and prevented the vehicle from being put into drive. I tried to get a hold of the Acura towing service but was stuck on hold for 20 minutes and hung up. I started the car once again, and no errors were shown. I was able to drive 1/2 a mile and the transmission once again disengaged into neutral and emissions system warning came up again and I pulled over once again. I once again waited 20 minutes and restarted the car and drove 3 miles to a shopping center parking lot and let the car sit for 1.5 hours. When I returned, I started the car and everything seemed fine, and I was able to drive 35 miles home with the emissions system warning and transmission system warning displaying but the car remained in gear. I took the car to the dealer the next day (with the car still covered under extended warranty), and Acura performed a software update (PGM-FI and TCM and PCM Idle Learn updates), for which they initially said I was responsible to pay for.
