2019 Acura Rdx

The contact owns a 2019 Acura RDX. The contact stated while driving approximately 35-40 MPH, the vehicle failed to exceed 40 MPH upon depressing the accelerator pedal. There was no warning light illuminated. The contact veered to the side of the road, where she turned off and restarted the vehicle, and the vehicle operated as needed; however, the failure recurred several times while driving. The contact stated that she veered to the side of the road, turned off and restarted the vehicle on each occasion, and the vehicle operated as needed. The contact stated that the failure had been occurring intermittently. The vehicle was taken to the dealer several times, but the dealer could not duplicate the failure. The contact stated that she had recorded the failure on video, which was sent to the manufacturer; however, the manufacturer provided no assistance and referred the contact to the dealer. The vehicle was not diagnosed nor repaired. The failure mileage was approximately 55,000.

My car has been shaking on acceleration but no engine light or any warning popped up. When I called an Acura dealership, they said they would have trouble diagnosing the problem without a light on. A few days later, while accelerating on the highway, my car started shaking violently and lost power. The engine light started flashing. I could have gotten into an accident because I could no longer accelerate on the highway. I had to slowly pull off to a safe stop. This could have been a dangerous and life-threatening situation. Someone could have crashed into me behind me and I could not quickly get into a safe area. I brought it to an Acura dealership and they could not find anything. The engine light had turned off. Though, when I took the car again, the car was still shaking on acceleration. I was afraid to drive at normal speeds since it is extremely safe. I took it to another personal mechanic and he was able to reproduce the problem. He saw there is a service bulletin out for just this problem. The possible cause is “humid air within the intake tract May condense and accumulate excessive moisture during steady driving.” I would have to replace the intercooler system and get the PGM-Fl software updated. This is a safety issue, and Acura has not released any recalls on this. The dealerships are also saying it will not be covered by warranty for me.

On July 24, 2022, while driving from Champaign-Urbana, Illinois back to our home in Lisle, IL, in a heavy rainstorm, our RDX suddenly started flashing the engine light and lost power on Interstate 57. We were fortunate to be able to maneuver it to the side of the road, and off the nearby ramp at Bradley, IL. We ‘googled’ the circumstances on our iphone, to learn that this is considered a serious, potentially life-threatening situation, and that Acura recommended immediate Service Bulletin 20-053, dated May 25, 2021, states the symptom as “The MIL is flashing with loss of power.” It indicates “Corrective Action” for the RDX as “Update the PGM-FI and replace the intercooler, the intercooler outlet pipe assembly and the intercooler outlet hose.” Affected vehicles include “ALL” 2019-2020 RDX models.” Despite the Service Bulletin that was issued, many RDX owners, noted the same response from their local Acura dealer. They note that the dealers “played dumb,” claim they could not locate a Service Code, nor “replicate the conditions and response” in the shop…. precisely my experience! In fact, the Service Receipt, indicates the car was driven less than one mile, hardly sufficient to replicate conditions. Acura Client Relations has refused to assist. I contacted the CEO Jon Ikeda but his office has not responded. I fear driving the car in wet conditions.

On 9/22/22 travelling on I-290 near Boylston, MA I was passing a large tractor trailer in the far left lane going up a hill. It was and had been raining very hard for at least the previous hour. When I stepped on the accelerator to increase speed, the car suddenly decelerated to about 20 mph and the check engine light began flashing. I was able cross all three lanes in very heavy traffic to the shoulder. I then slowly made my way off the interstate to a gas station right beyond the exit. My passengers and I were very concerned about the suddenness and the abrupt reduction in speed on an extremely busy roadway. A call to the nearest Acura dealer service department confirmed he had seen nearly the same symptoms the prior week under similar road conditions and the same model car as mine. He found no codes on the other car. I also notified Acura customer service who confirmed the existence of a Service Bulletin on precisely this issue (flashing light with loss of power).

Transmission was stuck in 1st gear. This situation happened to me while stopped at red light with auto idle stop engaged, when it restarted at green light, transmission got stuck in 1st gear, I drove for about 1/4 mile and still the vehicle would not shift gears. I pulled over safely to the curb, shut down the car, waited 10 seconds and restarted, vehicle drove normally back home I had it all recorded on my dash cam and took the car to the dealer, showed the video and there were ZERO findings, nothing was recorded on the car error logs according to the dealer.

The contact owns a 2019 Acura RDX. The contact stated that while at a stop light, the vehicle stalled. The vehicle failed to move or shift into neutral(N). The vehicle was towed to the local dealer where it was diagnosed that the fuel pump motor needed to be replaced. The vehicle was repaired. The manufacturer was notified but no additional assistance was provided. The contact stated that the failure was related to NHTSA Campaign Number: 21V215000 (Fuel System, Gasoline). The failure mileage was approximately 40,000.

on 2/3/22, after only 12 hours of owning the vehicle, I merged onto 287 South and upon speeding up and merging into the center lane, I lost all acceleration and my dash lit up like a Christmas Tree. An 18 wheeler was coming behind me in the middle lane at 65 mph while my car slowed down to 25 mph. I was thankfully able to get over to the side of the road without being hurt or even killed. Upon bringing it into the dealer, the codes showed that it was a bad engine coil and spark plug. This was repaired under warranty. Fast forward to 5/16/22, I exited the highway, came to a complete stop at a red light. Upon the light turning green, I went to accelerate and limp mode activated again. I have video of the incident and dealership is unable to find any issues with the vehicle. Both times it was either raining or had just stopped. I have asked that the Intercooler be replaced as part of Bulletin 20-053 however the dealership states my vehicle is not part of this bulletin although it lists the model and year. This is a serious problem that requires a recall. I hope Acura is not waiting for someone to get hurt before they take action!

I was driving for approx. 3 hours on the interstate and exited to return home. After stopping at the red light my car would not excel. The rpm where moving up to 4 plus but the car wouldn’t go over 20 miles an hour when pressing the excelerator. No warning lights came on but I pulled over and turned the car off trying to decide what to do. I couldn’t get back on the road driving 20 miles an hour because it wouldn’t be safe. I decided to restarted the car then I drove 2 miles home without incident. I will take the car to the dealer after the holidays because I’m scared to drive it. I bought the car with 25,000 miles and it now has 32,000 miles on it.

My 2019 Acura RDX suddenly lost power while accelerating on two occasions this year. Both times it occurred in clear weather with temperatures around 80 degrees. The first time it happened was on 7/15/2021 when I was accelerating onto a US Highway. The second time was on 10/4/2021 when accelerating from a stoplight. Both times I had to coast to the side of the road due to loss of power. I was able to restore power by restarting the engine. Please investigate since loss of acceleration can lead to crashes. For example, it can be deadly if it occurs while passing on a 2-lane road or making a left turn in front of oncoming traffic. Thanks.
