Vehicle goes into a "limp" mode during high speed freeway driving with little or no power during heavy rain. This has occurred 5 times in the 1st 20,000 miles and dealer cannot find problem after 3 attempts. This is a very dangerous and potentially catastrophic situation. This has rendered the vehicle not useable due to the safety concerns.

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.

Was driving down the highway when my car lost all acceleration and a whole bunch of warning lights went on, steering became hard etc. Got it over to the side of the highway barely. Car wouldn't restart, go into neutral or anything. Apparently the dealership says the radar was fault and killed the car while I was driving it and there was no way to disable the radar. If the radar is faulty it will kill all propulsion and also throw multiple errors in the car creating a hazard for the driver. It seems like this should be a recall.

Driving for 15 minutes engine stopped while going up a very busy bridge on I-10 - started shaking and flashing no brakes no steering contact dealer. Coasted to construction area on top of bridge as to not be hit by 18 wheelers. The vehicle was out of warranty by 1200 miles... that's ridiculous

- Sulphur, LA, USA

After a hard stop at a stoplight, when attempting to accelerate the car would not accerlate even when pushing hard and pumping on the gas pedal. Could hear the engine reving but would not go over 20 mph. Took it to the dealer the next day and they could find nothing wrong. Happened a 2nd time when attempting to pass a car. In that instance I recall speeding up to pass the car and once in front if it had to step on the brake due to a pending stop light. When attempting to accelerate again the car would not accelerate. Could hear the engine reving up, but the car would not go over 20 mph.

My 2019 Acura Rdx experienced a total, unexpected loss of engine power while attempting to pass a truck on a 2 lane highway. All propulsive power suddenly disappeared just as I expected the turbocharger to kick in for safe passing. I firmly depressed the accelerator a couple times with zero response from the engine. This was accompanied by a sense of the engine misfiring. My belief is that this propulsion failure is related to a turbocharger activation issue. Please note that while my dealer has found no ongoing engine problem in my car, the dealership has ordered turbocharger related parts and intends to install them next week. Also, while stranded, we searched online and found references to seemingly similar Acura failures that occurred in wet and rainy conditions. We were driving in cool and rainy conditions at the time of this failure. Fortunately, we avoided a crash and coasted to a stop on the left shoulder. Engine was still running and the car put itself into creep mode, which allowed movement to the right shoulder. A very dangerous and potentially fatal accident was luckily averted. The vehicle was hauled 130 miles to my local Acura dealership which reported an engine misfire indication from the car's computer but no further indication of prior or subsequent issues.

I was driving on a two-lane highway in rural Mississippi. Once on a straightaway and with plenty of space to pass, I attempted to do so. As soon as I accelerated, the pedal went to the floor, I lost all power, engine light flashed on, and I was trapped in the left lane with oncoming traffic racing at me. With less than two seconds to spare and with the help of downhill motion, I was able to squeeze ahead of the vehicle I was attempting to pass and into the right lane just as oncoming traffic whizzed by. I sat on the shoulder of the highway and literally shook for about an hour. The car was towed to Acura of jackson. While sitting at their dealership, I found all these similar complaints. Like all the others, no codes showed up and nothing could be done. They kept the car for three days and could not get it to replicate the situation. I drove it back to Texas and am just waiting for the issue to happen again...praying that if and when it does, it will not be a life-threatening situation this time. Why is this continuing to be reported and nothing is being done? others reported this happening in heavy rain. I was traveling at 70mph on a wet road at the time. It was cloudy, but it was not raining at the time. The car was in comfort mode at the time.

While driving my 2019 Acura Rdx I attempted to pass a slower moving vehicle. During acceleration my engine light started flashing and simultaneously the vehicle lost all power to the engine. This prevented me from passing and forced me to fall back in behind the vehicle I was passing. This was extremely dangerous and could have had catastrophic results if another vehicle was approaching. After falling back in behind the vehicle I pulled off onto the shoulder. I turned off the vehicle and waited about 2 minutes and upon turning it back on; it was back to normal. I paid nearly $50,000. To have a safe and reliable vehicle. This vehicle is so unsafe to drive with this issue it basically sits in the garage. Contacting Acura dealers / service departments they know about this but are waiting for the company Acura to come up with a solution. This vehicle is not safe and my life and family's life were put into jeopardy. Acura doesn't have the right to put their customers lives in jeopardy. They need to fix this issue or allow their customers to return this defected vehicle immediately.

2019 Acura Rdx advance sh-AWD odometer 12,900 Tuesday 01/14/2020 14:20; lkas on, comfort mode, engine idle stop/start cancelled with the button, 60 deg F. on a 300+ mile road trip, the latter half under heavy rain. Nearing my home, the rain was almost stopped, and as I acceleratedup a long steep grade, the Rdx felt like it ran out of gas. It just sputtered along up the hill until I came to a driveway and turned in. I noticed the engine light was on. I turned off the engine, waited a fewminutes, then it restarted and has been ok since then. I did notice the next day that the idle start/stop function is "unavailable" and the car continues to run with the foot on the brake. I do quite a bit of 2 lane travel, and often must pass slower trafficunder full power. If this situation occurs during a passing maneuver with short site distance, it would be disastrous. Based on this fear, my driving ability is now severely limited until this problem is diagnosed and resolved.

My brand new 2019 Acura Rdx that had 9200 miles on it shut down on me on the freeway. It was raining and I pulled out to pass, going about 75 mph, and it went into what I now know is limp mode and the engine light flashed on and off and the engine was making a different sound than normal. I had someone tailgating me, so I am lucky it didnt cause an accident. Got pulled over and called the dealership and they said it needed to come in. They speculate raindrops got on the engine filter (forget the name) and the car thought it was malfunctioning and shut down. I hadnt turned the car off because I was afraid id be stranded, so I dont know if it would have reset itself. Still, I bought this car for dependability and ive lost all trust. I had had three Acura cars before this. Ive been told theres no fix and engineers are working on it but they couldnt recreate the situation and its working okay now. This is a safety issue. I could have been on a two-lane passing and couldnt get back in when it shut down before an oncoming car! so I cant drive it in the rain or pass now" the dealership had one other Rdx do the same thing and im reading several online. I feel like its russian roulette. Do I just have a lemon or is it a design flaw" im scared! the car is still at the dealership, but there's nothing that can be done because everything checks out. They don't honestly know what to do, so the possibility of being stranded or missing a flight or being injured or killed is not off the table! they know they have a problem but not making it public knowledge. It's a brand new design so there must be a flaw.

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 30, 2019, I was passing a dump truck on rt. 539 in New Jersey, I had just accelerated to complete the pass. As I was completing the pass, the engine lost power and the engine malfunction light began blinking, I've been told the vehicle went into limp mode. The car decelerated and would not go over 20 mph. I was quickly able to pull onto the shoulder to avoid being hit by the truck I just passed. Once in the shoulder, I turned the vehicle off. When I turned the vehicle back on, the engine malfunction light was no longer flashing and the car resumed normal operations. I contacted the local Acura dealership. The dealership kept the vehicle from October 30 until November 1, I was told that there were no stored codes on the vehicle. The vehicle was test driven for 60 miles, the dealer was unable to duplicate the issue. The vehicle was returned to me, I was informed if the issue occurs again to bring it back. This vehicle had approximately 10,500 miles on it at the time of the incident. This is a very dangerous problem, I narrowly avoided being in a car accident.

- Tuckerton, NJ, USA

Car goes into "limp mode" and loses all engine power at highway speeds. Has happened 4 times, twice putting my safety in jeopardy. The first time it happened I was accelerating onto the highway. I pulled over and restarted the vehicle, attributing it to a one time glitch. It happened the second time when I was attempting to pass another vehicle on the highway. I called the dealership and they advised me to restart the vehicle and drive into their shop. The third time it happened I was accelerating onto a highway from the on ramp. I called and left a message for the dealership. The fourth time it happened I was attempting to pass a semi truck in a construction zone. My Rdx lost all engine power and I was forced to turn on the flashing emergency lights and coast until I reached the end of the construction zone. Acura has repeatedly denied the existence of this problem and told me I was the only one experiencing this issue. The approximately 20 complaints filed with the NHTSA indicate otherwise. Acura has refused to resolve this issue, claiming they cannot duplicate it. A recall should be instituted before someone is injured or killed by this serious safety issue.

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.
