2 Check Engine Light On problem of the 2020 Acura RDX

Failure Date: 11/25/2020

I was driving on a freeway at 4:30am when I suddenly lost all power from the engine and it went into limp mode. The check engine light was flashing and fortunately there was no traffic so I was able to pull off the road. I shut off the car and sat for a few minutes and when I restarted the car everything was working fine. I had a 12 hour drive ahead of me and I never stopped thinking of how that could have ended up so badly. Later that day as I was driving through atlanta I shuddered to think what could have happened if this lack of propulsion had occurred. My guess, quite bluntly, is that I probably would have been killed. I have read online of this problem happening to a significant number of other people. Acura needs to be held accountable before someone is killed!.

6 Check Engine Light On problem of the 2019 Acura RDX

Failure Date: 09/02/2020

This is the second complaint for this vehicle, the previous complaint was assigned NHTSA id number: 11277657. Similar to the incident that was previously reported, while driving on a highway at a high rate of speed, attempting to pass another vehicle, the car went into limp mode, lost acceleration, steering became difficult, and the check engine light came on. Luckily, we were able to safely get the car into the right hand lane and pull off into the shoulder. We turned the vehicle off and when we turned it back on the vehicle operated normally. As with the previous incident, this occurred in the rain. The car was brought to the dealership and, as with the previous incident, we were told they could not duplicate this issue and the vehicle was returned to us. We were told that if the issue occurs again to bring the vehicle back to the dealership. As stated in my previous complaint, this is an extremely dangerous malfunction that could result in a serious accident. This time my two children were in the car. What is it going to take for Acura to find an acceptable resolution to this problem? how many of these malfunctioning vehicles are on the road???.

7 Check Engine Light On problem of the 2019 Acura RDX

Failure Date: 08/26/2020

On two occasions, when driving in wet weather at 50-60 miles an hour on a 2 lane road, I accelerated to pass a vehicle and the engine suddenly lost power, went into "limp mode" and the vehicle was unable to complete the passing maneuver safely due to loss of acceleration. Check engine light flashed continually as the vehicle coasted to an eventual stop. Pulled off road, turned vehicle off, and then restarted it after a couple minutes and the engine light was no longer blinking, vehicle was operating normally. Sudden loss of acceleration is extremely dangerous at highway speeds and could easily result in a collision.

9 Check Engine Light On problem of the 2020 Acura RDX

Failure Date: 07/30/2020

While driving at a consistent rate of speed on a 65 mph highway the vehicle suddenly and without warning lost engine power. The vehicle began to rapidly drop speed and the check engine light would blink when the accelerator was depressed. I was forced to abandon the highway and pull over onto the shoulder - not in an emergency lane - in between north and south bound traffic because the vehicle would not accelerate over 20 mph or exceed 2,000 rpms. After 3 hours of waiting in this dangerous location Acura roadside assistance was unable to locate a tow truck. I turned the vehicle off and back on and noticed the check engine light ceased blinking. I then proceeded to return home and the problem returned a second time, this time accompanied with numerous indicator lights (e. G. , awd problem, abs problem, etc). The vehicle was towed to pohanka Acura in chantilly, virginia. I was told the first time they cleared the codes they returned, but after a second time they did not. They were not able to replicate the problem, did not fix anything, and said it was caused by fuel choice. This is significant problem and safety risk known to Acura. There is a patent history of Acura choosing to not identify the root cause, associate this anomaly with fuel choice, and return the vehicle to the owner. In my opinion this is a negligent business practice and Acura should be responsible for any injuries or damages associated with these unexpected, unannounced "limp mode" events.

10 Check Engine Light On problem of the 2020 Acura RDX

Failure Date: 07/10/2020

2020 Acura Rdx with approx 6,200 miles. Driving from pittsburgh, PA to new jersey. I reached new jersey after driving from pittsburgh. There was moderate to heavy rain showers during the drive. The rain ended prior to me entering new jersey. I exited the jersey turnpike for the on ramp to 195 east. I was going approximately 45 miles mph when I pressed the gas pedal to accelerate so I could safely enter traffic. I could feel the engine give way as I pressed the pedal. The car decelerated and the check engine light illuminated. I pulled off the highway to the side of the road and put on the flashers. I let the car run at idle. The check engine lite went off so I tried to accelerate the vehicle with no luck. The engine would rev a little but the car would only accelerate to approximately 25 mph. I tried this multiple times. I was near an exit and the vehicle was able to move at a slow speed so I drove approximately 2 miles to a friend's house. Again, the vehicle would not go over 25 miles an hour. After reaching my friend's house, I turned off the ignition. About 1 hour and 30 minutes later I turned on the vehicle. This seemed to fix the problem and I was able to continue home with no further issues. The check engine light remained off. Acura looked at the car but there was no record of the problem and they could not duplicate the issue. Not sure if it was an electrical issue or an engine issue.

11 Check Engine Light On problem of the 2019 Acura RDX

Failure Date: 07/08/2020

6 hours into a cross country drive, my wife went to pass a line of slower moving cars in a designated passing area on us45 in ms. As she push down on the accelerator at 55 mph, the car dropped into a lower gear as it accelerated to 60 mph, then bucked and when into limp home mode. The check engine light started flashing, with speed dropping rapidly towards 20 mph. She was able to get safely towards the side of the road, where she switched off the engine. A minute later, she restarted the engine. The check engine light was out, and the car responded as if nothing happened for the remaining 2 hour. Drive home. I was able to pull 4 codes from the obdii system: p0300, p0301, p0304, and c1555. The first three are for misfire of the ignition system, while the last is for an incompatible scan tool. The car had half a tank of 93 octane gas, temp was around 90 with high humidity. The car has 25000 miles. This could have resulted in a serious mishap if there had been someone behind her attempting to pass also. There are several reports of the same thing happening to other 2019 Acura Rdx's on this reporting site, as well as on an Acura Rdx forum. Someone at the NHTSA needs to get Acura to get on the ball and fix this issue before someone gets killed.

12 Check Engine Light On problem of the 2020 Acura RDX

Failure Date: 05/23/2020

After driving on secondary roads for an hour, I entered a highway. I was accelerating on the entrance ramp and noticed a car going very slow in the slow lane. I put on my blinker, accelerated more and moved to the middle lane of the highway. The car immediately went into �limp mode�, losing all power and the check engine was blinking. I could not pass the car that was going about 30 mph and had to apply my brakes in the middle of a highway as trucks were bearing down on me. This was terrifying! I was able to pull off to the side and shut down the engine. After 30 seconds I restarted the car and all power was returned with no check engine light. The dealer could find no problem, but Honda needs to fix this before someone gets killed.

13 Check Engine Light On problem of the 2019 Acura RDX

Failure Date: 12/28/2019

We turned onto the on-ramp of i40 west in arkansas at exit 58 heading west. I accelerated to get up to speed to merge onto the highway. When I reached 70mph the car stopped acceleration and very rapidly slowed to 20mph in front of multiple cars and semi trucks. I was lucky to have been missed by the traffic behind us and was able to get to the right shoulder. The car would not accelerate past 10-20mph. We limped to the next exit and found a parking lot. I turned the car off and back on and it seemed to be working correctly again. My entire family could have easily been killed! during the incident the check engine light came on and remained on until turning the car off and back on.

14 Check Engine Light On problem of the 2020 Acura RDX

Failure Date: 11/23/2019

From the day I took delivery of my 2020 Rdx advance in August, I've been completely crazy about it. Now, however, I'm feeling sad and disillusioned, but more importantly, I don't feel 100% safe driving it. Recently, after spending a few weeks in georgia, we were driving back home to northern virginia on I-85n in north carolina. It was and had been raining steadily the entire trip. There was moderate/heavy traffic moving at speeds between 60-75/80 mph. Somewhere just south of charlotte, the car suddenly started slowing down, even though I was pressing the accelerator! it was barely moving in the middle of traffic. The check engine light was blinking and the engine was rattling and sputtering. I immediately turned on the hazards and started crossing the two far right lanes to get over to the narrow shoulder. Terrifying. Fortunately, we were only about a 1/4 mile from an exit. We slowly made it on the shoulder to one of gas stations there. After checking the support section in the app and calling a tech at my home dealership, I shut the car off and let it sit for about 15 minutes. It started and we were able to finish the trip without further incident. We made it home safely, but the remaining six hours of the trip were mentally excruciating. We drove as slowly as safely possible in the right lane. I couldn't get it out of my head that it could happen again at any moment. And, I can't say it hasn't crossed my mind that I won't be able to get over that extended feeling of uncertainty while driving it. At least, not for now. I took it to the dealer on 11/25/19. They said they could not duplicate the issue, and that there were neither error nor fault codes stored. I had been hoping they would give me some explanation and reassurance that everything is fine. I wanted to feel 100% that the car is still safe to drive, but I'm not feeling that now.

Failure Date: 07/29/2019

I was accelerating hard onto a highway on ramp when the check engine light turned on and the car went into "limp" mode.

The car returned to normal operation afterwards although special care was taken to minimize strong acceleration.

18 Check Engine Light On problem of the 2019 Acura RDX

Failure Date: 07/11/2019

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.

19 Check Engine Light On problem of the 2019 Acura RDX

Failure Date: 04/19/2019

A couple of days ago, on�April 19th, my wife and I were driving through�columbus, GA. It was around 7:00 am and raining. We had been driving about 1 1/2 hours and�we were only going around�30 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. � I�turned 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.

21 Check Engine Light On problem of the 2007 Acura RDX

Failure Date: 04/04/2017

I purchased the car in April and I never received my registration, and plates, they had never mentioned to me that the status of the car was salvage. I also wasn't informed they were out of business when I was in process of purchasing my car. Since I purchased the car the check engine light has always been on, and the back of the car is messed up.
