Check Engine Light On problems of the 2019 Acura RDX

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???.

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.

Driving at hwy speed, raining and accelerated past slow semi trucks, check engine light came on and vehicle went in to limp mode almost causing an accident.

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.

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.

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.

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.

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 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.

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.

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".
