    I was accelerating up a hill on a WV highway in a steady rain, the engine cut power, the check engine light flashed on and off, further throttle input did nothing, the car slowed on its own. I had to pull over from the left lane dangerously cutting in front of vehicles in the right lane as I could no longer maintain highway speed. Shut the car down and waited to rekey. Vehicle has operated fine ever since. The dealer has not been able to duplicated the issue (two weeks afterwards)

    What component or system failed or malfunctioned? Car automatically applied brakes on several occasions, despite no obstacles in front of the car. Incident 1: While driving through an 3-way intersection, the car slammed on the brakes automatically. There was a van in the opposite lane waiting to turn left. There was 2-3 feet of space so there was no risk of collision, but the car slammed on the brakes causing me to come to a sudden stop in the middle of the intersection. Incident 2: I was changing lanes to go past a stopped car in the left lane (It was waiting to make a left turn) The car automatically applied brakes, even though I would not have hit the car. Cars behind me had to slam on their brakes to avoid rear-ending my stopped car. Incident 3: While driving on a freeway at 65 mph with light traffic and no cars in front for at least 1000 ft the car flashed the automatic brake warning. It did not actually apply the brakes, but could have caused an accident considering the speed. Incident 4: While driving on a 2-lane road with cars parked on the sides of the road, the car displayed an automatic brake warning despite no collision being imminent. Incident 5: While driving down a suburban street with no trees or obstacles in sight, the automatic brake warning flashed. How was safety put at risk? Sudden stopping in a road, highway, or intersection could cause an accident. I am concerned for my safety, because if the car stops unexpectedly in the middle of the road, other cars may hit me. This is the same system used in some Hondas, so a recall of Honda vehicles may need to be extended to Acura vehicles. Has the problem been confirmed by dealer? Yes. The service advisor told me that his car has the same problem, but that it is normal and there is nothing they can do about it. Were there any warnings? Usually happens when there is a radar reflective object above or off to the side of the path of travel. The BRAKE warning appears when automatic braking is applied.

    All software systems failed, disabling the vehicle. Error messages included failure in braking, steering, and other vital systems. Acura roadside assistance determined that the car had to be towed to the nearest dealer. The dealer confirmed the issue was a "DTC P061B PCM internal malfunction" and performed a "PGM-FI software update to correct the issue." The vehicle was completely disabled, and we were 4 1/2 hours from the nearest dealership. There were no warnings or communications prior to the incident.

    My experience is in the attached file. My concern is Honda (Acura, same company) issued a service bulletin with VIN ranges (which my vehicle falls in) and yet there is no diagnostic error code to show it happened to the car, repair persons/dealerships can and have denied fixing anything because they can’t diagnose it and it’s in the owner’s manual directing the owner to take it to the dealer for repair. That’s a big disconnect. Luckily, I was able to dig to find the bulletin and provided it to my dealer with the description of what happened and they’re going to fix it. But that doesn’t help anyone else. You really should put pressure on American Honda Motor to issue a recall and do it right.

    One week ago 6-20-22, my car started to ‘chug’ and slow down as I was accelerating up a hill on a highway. It was almost as if my car was losing power. When this happened about 10 warnings signs came up on my dash. I drove it directly to the dealership. They replaced my oil saying the pressure was low. All was well for the day after 6-21 when driving it home from dealership. On 6-22 I went to merge onto a local highway from a stop sign with traffic coming at 55-65 mph. My car would not accelerate over 25 and I was unable to pull of. Thankfully I pulled off onto the next exit. I could have easily been rear ended and hurt. This issue since will go away if I shut off my car and turn it back on, but not every time. It is still chugging and losing power when I drive and all the errors on the dashboard are coming up randomly. I drive A LOT everyday for work and this problem is really scaring me knowing I or others could get hurt.

    Purchased my 2021 in November of 2020. Two weeks after, i was driving with adaptive cruise on at 65 mph on a freeway. 100 yds ahead i could see a diesel going slower than i, so i looked and saw no one coming at all, so i moved over to the passing lane. I got 5 feet into the lane and the car slammed on its brakes, on its own!!! Thank god no one was behind me or i might have died!! I reported this to Acura within 1 week, and then reported it to DOT the next week. I own one of the first 2021 s made, so i didn’t see a lot of feedback. Now after a year and a half i get on the DOT website and see many complaints like mine. This has happens to me maybe once every 3 weeks. Why has the DOT done nothing about this??!!! Also the DOT says there are no recalls on my car but if you go to the Acura website it says my car is under recall for a driveshaft problem, of which i never received a notice. Why does the DOT exist??
