On Wednesday, Oct 16, 2019, I was driving this Rdx for about 2 hours, and was going South on N Carolina rt #171 in a steady rain on a flat road. I drove behind a 18 wheel log truck for 10-15 minutes at 50-55mph before confirming there was no vehicles coming the other way. When it was clear for 1-2 miles, I floored the accelerator to pass the log truck. The Rdx leaped forward at first, but halfway past the log truck the vehicle lost power and slowed to 35-40 mph or so (maybe slower, as I am guessing--- I was not looking at the dash). I was scared that I could not complete my pass of the truck. Fortunately, after 5-10 seconds, the truck driver noticed something was amiss, and he slowed down to let me pass at my slower speed. I pulled off and was grateful for two things. First that no one was coming the other way, as a head on collision could have taken place. Second, that the truck slowed to permit me to pull off on the right shoulder. This took place about 220pm. After pulling to the shoulder, and leaving the Rdx running, I waited for several minutes, and tried to pull forward. The limited power condition remained. And the orange engine symbol continued to appear on the dash. I suspect the orange symbol appeared when I lost power, but I wasn't looking at the dash. After several more minutes, I turned the car off and waited for several more minutes. When the car restarted, the symbol was gone, and regular power had returned. I drove about 100 yards, and then re-entered rt#171 when there was no one coming behind me. The Rdx operated fine then and I completed a 3.5 hour drive to myrtle beach. I drove normal from there to naples fl over the next 5 days with no issues. But, I didn't try to accelerate by depressing the pedal to the floor in the rain. There was a clear safety incident at 220pm Oct 16th..

On October 6, 2019 I was traveling West on interstate 80 in western Pennsylvania at about 70 mph. Accelerated in the left lane to pass another vehicle when the engine lost power.. pulled over to the shoulder as maximum speed dropped to 40, then 20, then about 10. Check engine light was blinking an engine was running rough. Had car towed to dealer. It is currently being evaluated.

- Broadview Heights, OH, USA

Vehicle lost all engine power when accelerating to pass from approx 60 mph. Check engine light came on, pulled to the shoulder and power was still not present until the vehicle was shut off and restarted. Has happened on a few other occasions, very dangerous if passing on a 2 lane highway.

- Lee's Summit, MO, USA

While attempting to pass another vehicle on interstate at around 70 mph, car power fails losing most power and engine light blinking leaving us very unsafe! once getting to the shoulder and restarting car, it is normal again. This has happened 4 times now. Acura can't find any codes and does not have an answer for this saftety issue!

- Rogers, AR, USA

Engine stalls while vehicle is in motion. Vehicle is already in motion, 40 mph. We simply stepped on the gas paddle and the car stalled on the left lane.

- Southwest Ranches, FL, USA

Vehicle would not change gears, stuck in first gear going over 50 mph on the highway.

- Carpentersville, IL, USA

I was accelerating hard onto a highway on ramp when the check engine light turned on and the car went into "limp" mode. I drove at 40 miles per hour to the next exit and turned off the car as instructed on the manual. The car returned to normal operation afterwards although special care was taken to minimize strong acceleration.

I just brought a new 2019 Rdx, it only has 315 miles (it has been only two and half weeks).I was driving on the highway on my way to work. I lost acceleration on my vehicle. I tried pressing the accelerator no reponse. All the warning lights came on, the engine light, AWD, brake system, power steering, stability and traction. Luckily I was able to get on to the shoulder. As I am reading similar complaints I notice that some people were able to shut off and turning on back the vehicle, resetting the car and resolving the issues. Unfortunately for that did not work. I had to be towed back to the dealership.

I just bought a new 2019 Rdx aspec last Friday, and it only has about 500 miles on it. I was driving home tonight and went about 60mph to pass a car and my car completely lost power. I tried pressing the accelerator and I had absolutely no response. My check engine light started flashing. Fortunately, there was a police officer who was able to guide me to the shoulder. I restarted the car and the engine light was gone and I was able to drive off. However, the car still does not seem to have a full throttle response and the RPM is staying at about 3500 in normal mode. The auto-disable engine feature is also not working anymore. It had rained earlier in the day but it was not raining at this point but the roads were wet. I had been driving for about 30 minutes continuously before this at about 60mph.

- Woodbridge, VA, USA

I was driving on a major highway accelerating to enter a toll lane. The engine light started flashing and I lost acceleration ability immediately. I had to cross 6 lanes to get to shoulder across a major highway.. I had already been driving for 1.5 hours with no issues. The dealership says there is no record of the issue in the car logs and therefore nothing they can do. This was a very dangerous situation and I was lucky that fellow drivers allowed my limping vehicle access to the shoulder before the car completely stopped. Shutting off and turning back on the car reset the issue and I was able to drive normally. Engine idle stop no longer worked after this happened. I had passed through a major rainstorm prior to this issue - not sure if that was related.

After leaving work on May 16, 2019, I accelerated from a stop light onto highway 1 in san luis obispo. Immediately, the car stalled, lost all power, and a warning light illuminated stating "AWD malfunction, AWD not available." I pulled off the road, turned the car off. I re started a couple minutes later, and made it home. However, the car appeared to be operating on about 50% power, as it struggled to maintain highway speeds.

While driving on a 2 lane highway on May 25, 2019, I attempted to pass a slower moving vehicle by flooring the gas to overtake them, and crossing the hashed highway line. I was driving in an area where the road undulated, so passing was only legal in stretches where the road was flat with distant visibility. As I moved over and floored it to pass, the car hesitated and lost propulsion, and the engine light began flashing. I was forced to transition from an aggressive, but legal, passing maneuver, to swinging back into position behind the vehicle I was attempting pass, and in front of another vehicle tailing me, but now I was losing speed. The car behind me was forced to brake hard, and my mechanical failure put them and me at risk. As I slowed due to lost power while in limp mode, I moved to the shoulder, shut off my car, and waited a few minutes. I restarted and experienced no continuing issue. This issue is so far isolated in my experience, however I have researched it on the following site and see multiple reports of the same issue: Https://acurazine.com/forums/3G-Rdx-problems-fixes-458/limp-mode-2019-spec-971802/page3/.

My Acura has "stalled" twice now while passing (once at about 4800 miles and the other at about 5600 miles on odo). Both times the car was in cruise control and lane keep assist and traveling on a highway at about 60mph. Both times I was overtaking a large vehicle that was to the right of me. Both times, I put the pedal to the floor, the car accelerated for only a split second, then lost all power, the engine light started blinking and went into limp mode. I had to cut across several lanes of traffic with no engine power to get the shoulder. (very dangerous.) both times, when I shutdown and immediately restarted the car, it then ran normally. However, both times after this happened, the car's idle start/stop function stopped working (the engine never shut off at stops). So far, I have not been able to purposely recreate the problem when I try to do so in safe driving conditions. The first time I took it to the dealership, they didn't find any code or anything wrong with it. However, whatever they did caused the idle start/stop function to start working again. This time it has been 6 days and the idle start/stop function hasn't activated once (I have not returned to dealer yet). Acura client relations claims they will have a field technician test my car, but I may have to wait weeks or months for that to happen. Other owners are reporting near identical problems on https://www.carcomplaints.com/Acura/Rdx/2019/engine/engine.shtml this is going to result in a car crash at some point for some driver, so urgent attention is needed to resolve the problem.

A couple of days ago, onapril 19th, my wife and I were driving throughcolumbus, ga. It was around 7:00 am and raining. We had been driving about 1 1/2 hours andwe were only going around30 mph when I accelerated to pass a dump truck. The 2019 Rdx (6000 miles) started accelerating and then lost all power. I was able to limp over to the side of the road without getting run over by the dump truck but it a was very scary couple of minutes. Iturned the Rdx off for a minute, restated and then continued our trip. I took the Rdx to the Acura dealer in macon the following day and even though the check engine light came on no codes were stored. The service department did a hard reset of the system hoping to fix the problem. They seem to think that Acura is coming out with a software fix soon but that always seems to be the standard answer. I'm now afraid to let my wife drive the Rdx. Acura needs to fix this problem asap before someone gets killed.

I am submitting this ticket to document a hazardous scenario that I have experienced two times since purchasing my brand new 2019 Acura Rdx. Incidents occurred while driving in Ohio and Pennsylvania on cool days (ambient temperatures between 30 and 50 deg Fahrenheit), with and without rainfall. The following conditions were true for both occurrences. While driving on an interstate highway with adaptive cruise control [with low speed follow] and lane-keeping systems enabled, I decide to overtake a slower vehicle ahead of me. I depress the accelerator pedal without disabling the cruise control functions and change lanes to the faster lane. Just as I execute this maneuver, the engine simultaneously goes into limp mode -- the maximum power output decreases dramatically and the malfunction indication lamp (cel) is blinking. At this point I have to get across all lanes of the highway to pull onto the shoulder, and I have to do this while the vehicle is slowing down. Referencing my owner's guide, I see that the blinking cel indicates a misfire in the engine's cylinders is detected, and as instructed I turn off the engine in a "safe" place and wait for the engine to cool down. When I restart the engine, the cel is cleared and the vehicle resumes normal function. I took my vehicle in for its first service appointment yesterday. I provided this anecdote to my service advisor, and asked that we check error code logs and inspect component systems for damage. I was informed that there were no error codes logged, and that there should be such a log if, in fact, the cel was indicating. All component systems passed inspection/diagnosis. I am attaching a pdf containing the full description text of the ticket submission that I have made to Acura client services.

When driving above 65 mph and passing, my engine has stalled on three different occasions. Once at 1200 miles and the other twice in one day at 4,000 miles. The car obviously loses all power causing me to have to merge right in traffic to the shoulder to restart the car. Each time is was under full acceleration and in high traffic conditions.

- Lake In The Hills, IL, USA

Traveling on interstate highway, hit the gas to get past another car, and car lost power and the engine light started blinking. Pulled over to shoulder, shut it down, restarted, and it was fine after that. Weather conditions were very humid. Fortunately was not rear-ended but was a very dangerous situation. Took car to dealer, no codes were found. Other owners have reported similar experience with this vehicle at similar speeds and weather conditions.

- Schnecksville, PA, USA

After driving for an hour on the highway about 65 mph, the check engine light came on and I was unable to accelerate. I had to pull over on the highway, and shut my car off and turn the car back on. The car went into "limp mode"

- Chester, NJ, USA

After driving 100 miles between 70 and 75 miles an hour in left lane of 3 lane freeway, the engine quits and goes into limp mode producing almost no engine power. In limp mode the engine ran, but only produced enough power to for car to do 20 mph. Turned of engine, checked oil and coolant, both fine. Re-started car, ran normally, drove remaining 60 miles home at 60 mph with no further issues. Dealer had SUV 19 days and cannot find a problem. Very lucky not to have a serious accident as had to cut across 3 lanes of traffic to get to shoulder with no engine power.
