2021 Acura Rdx

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 off the engine for about 10 minutes, then I restarted the car again and got back on the road. This time, everything seemed normal, but I was so scared and worried the car might suddenly not respond again. Fortunately, I was able to get home eventually without any additional problems.

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. I was luckily able to barely avoid a collision with the truck that was approaching. After the light started flashing I was unable to turn the knob to switch drive modes (it was in snow mode at the time this all happened). I was unable to do anything but attempt to drive to safety with severe power loss. I was able to coast my car with minimal accelerator response to the next exit off the turnpike and into a motel parking lot. I shut down the car and then turned it back on. When I turned it back on, the MIL light was no longer flashing and I had normal power restored to the vehicle, but interestingly the auto stop/start feature no longer worked. I was able to drive the remainder of the way to Pittsburgh without any further loss in power, though I was anxious the entire drive considering the major malfunction I had just experienced while attempting a merge at highway speeds. The vehicle only had approx 10,500 miles on it at the time of the incident. The vehicle is currently at the dealership being diagnosed. A case has also been opened directly with Acura/Honda.

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.
