2021 ACURA RDX Vehicle Speed Control Problems

Drove into parking lot and as I was pulling into the parking spot next to the building, the vehicle started to surge forward as if I had my foot on the gas instead of the brake. The sudden surge caused the vehicle to plow into a brick building causing about $10K damage to the vehicle and $5K to the building. This was not the first time this sudden surging occurred. It happened at least 3 times previously, and one time since. Fortunately, the other occurrences did not lead to any damages, but just some anxious moments. I took the vehicle to the dealership to get checked out after the last occurrence, but they said they couldn't duplicate it. I thought it might be some sort of "unknown" problem, until I started reading on Facebook and other internet websites of other people having the same scary "surging" engine issues. I believe...

On 2-10-2024 I was driving the 2021 RDX SH-AWD on I-40W in TN with my daughter in the passenger's seat. It was raining. After about 2 hours of driving, at about 3:00 pm, I took a break at a Rest Area near Buffalo Valley. After ~20-min rest, I restarted the car and tried to merge back onto I-40W. I was accelerating towards the speed limit of 70 m/h, but suddenly, at about 65m/h, I felt the car losing power. I could not speed up anymore: the car did not respond to the gas pedal and the speed dropped to about 40m/h. The orange engine light started to flash on the dashboard. A truck nearly piled on me from behind. Cars and trucks from behind had to switch lanes quickly to avoid collision. I was able to pull over to the shoulder and stopped with my emergency light on. I turned...

On 12/22/22, I was driving in a 2021 RDX SH-AWD with my pregnant wife and 2 year old son from Media PA to Pittsburgh PA . It was rainy and 35-40 degrees F the whole drive. Approximately 4 hours into the drive we stopped at a rest stop on the PA turnpike to get gas. While attempting to merge back onto the turnpike from the service road to the right of the turnpike, a truck was coming up behind me in the right hand lane of the turnpike. I was traveling approximately 40mph on the service road, so I went to accelerate to safely complete the merge in front of the truck. Near the end of my acceleration sequence (I estimate I had gotten to approx 65mph) my car went into “limp mode”. I felt an unexpected and immediate loss of power and my check engine light/“MIL” began flashing yellow....

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...

I own a 2021 Acura RDX that was purchased new in February 2021. In the 11,500 miles I have driven it, there have been zero problems until yesterday. However, yesterday, when driving on an Interstate highway at 70 mph, in the rain, while passing a semi truck, my Acura RDX suddenly went into limp mode and the check engine light began flashing. After pulling over to the berm, and driving in the limp mode to the next exit, I turned the engine off. When I turned the engine back on it functioned normally and the check engine light went out. The engine has functioned normally for the approximately 100 miles I have driven since that time. Since there is no problem now, I have not taken the vehicle to the dealer to be checked since I felt that they would find nothing. When looking up this problem I found that...
