I have a recall on my 2019 Acura MDX for a faulty fuel pump. I have called 2 different dealers in my area, the first said they wouldn't have the parts to fix the car until December 2024 at the earliest, the second just stated that they don't have the parts. It seems to me this is quite a bit of time to be driving with a suspected faulty fuel pump. It is April 30,2024.

I have three recalls on my vehicle. I am trying to get them serviced and the Acura dealership is stating that they do not know when they can service the fuel pump because they haven't created/issued any parts. They will not let me book to service/fix the connector rod bearing before August. I am concerned with the safety of my vehicle due to these recalls and not being able to get them fixed ASAP.

While driving the vehicle at highway speeds the accelerator pedal became unresponsive. Additional force on the pedal pushed it to the floor with no response from the engine. After letting off the pedal while trying to pull the vehicle over to a safe location along the road, a press on the pedal from fully released, caused the engine to rev up and propel the vehicle again. This has happened 3 times but is very random, and not easily reproducible. It is a very unsafe condition when it does happen as the vehicle loses speed, and the driver no longer has speed control!

I pulled up to a stop light at a busy intersection/highway exit and, after depressing the brake, the vehicle abruptly turned off and shifted to neutral. The brake became very difficult to depress and the parking brake enabled on its own. The entire dashboard lit up and the car would not shift or respond to any input. The vehicle would not turn off, turn back on, or shift for approximately 15 minutes. After this, I tried to turn the car off and it finally did, I started it again and was able to pull off the roadway. We just recently (within the past 2 weeks) had a recall done to update the auto-stop system. This occurred 1x prior to the recall and now this has happened again. My young children were in the car both times and this put us all in danger.

During Idle stop at red light car stops and goes into neutral and engine stalls. 2019 MDX won't move unless completely restart the car in the middle of busy intersection. High risk for accident and injury. There is few recall mention in Acura site for 2019 MDX, but when input vin number its claims no recall to this vehicle. Need urgent help.

I have had problems with the car stalling or shifting to neutral from drive after the auto stop feature is engaged. This typically happens when the engine tries to restart after having shutoff at the stop. It is difficult to replicate the problem and the dealer can't seem to replicated the problem but it has happened to me many times, particularly in hot weather or after long drives. Typically it happens after a long drive or a lot of around town driving (maybe when the engine is hot?). The dealer does not believe it is related to the fuel pump replacement but that is when it seemed to have started happening but this is entirely speculation. Very frustrating as I have been to the dealer 3 times with the problem and they cannot "replicate" it. They supposedly also replaced the battery and updated the software in the car but that has not solved it. I am growing concerned because it is very dangerous, particularly when stopped at a busy intersection. The last stall happened and it took a minute or so to get the car running again at a busy and large intersection. I am also worried about the happening when on an incline. It doesn't happen all of the time, sometimes there is just a hesitation but the car starts and lurches forward. I have a 2019 with about 35K miles on it and have used primarily for long distance trips and not much around town driving. I have attached the dealer work orders for the three visits but stopped bringing the car in because it has been a waste of time as they are unable to find the issue. Also, I have reported the issue twice to American Honda and they have sent me back to the dealer with no results. This is a dangerous situation and I noticed that there is a related recall for the Acura TLX model with the same engine. This problem is ongoing and has happened to me twice in the past 2 days if I forget to disable the auto shutoff feature. Thanks.

On several occasions when auto start/stop is engaged the vehicle will shift into neutral on its own upon restart. The engine will just rev and not go back into drive until you put it in park and then drive again. This has caused us to stall in front of a semi and 2 other vehicles. The dealer has replicated the issue on multiple occasions and is now there for a 3rd time. First 'fix' was charge the battery Second 'fix' was adjust exhaust and transmission valves Third 'fix' is replacing the fuel pump There was a 2019 recall for Acura MDX but this VIN does not show up for that.

I think this recall needs to be expanded: Honda and Acura have recalled 2019 and 2020 vehicles including the CR-V and Accord for fuel pumps which can malfunction and cause the engine to lose power. My wife recently had her 2019 MDX stall on her in an intersection and she had to turn off the car and turn it back on so it would work. It sounds exactly like the below: -??While driving, the vehicle shifts into Neutral, the transmission indicator comes and DTC P0657 (actuator supply voltage circuit/open) is stored. The driver will not be able to select any other gear until the vehicle is turned off and restarted. Update the PGM-FI [programmed fuel injection] software and the TCM software, clear any DTCs [diagnostic trouble codes], and do the PCM [powertrain control module] idle learn procedure.-?? - TSB 15-034 Additionally, May 23, 2021 we had an experience where the same MDX decelerated as we merged into traffic at I-30 and I-820 in Ft. Worth. I let off the accelerator going 60-70 MPH and then stepped on the accelerator to complete my merge and there was no power. Speed dropped to around 20 almost instantly. I had to completely let off the accelerator and depress it again to get going. Very scary situation considering how fast people drive on Texas freeways. These are two big issues Honda/Acura needs to address ASAP as both put consumers at risk of injury and possibly death.

The car caught fire spontaneously in the parking area. We called 911 and the fire brigade took about an hour to get the fire under control. We had gone to chickfila (about 6 miles total distance) and the car had been parked for maybe 5 minutes when we saw a fire engulf the front portion. I put water on it while waiting for 991 response.
