Transmission does not down shift appropriately when slowing or traveling a low speed and the need for fast acceleration is needed. There is about a 3 second delay before any throttle response or acceleration. Car is stuck in 5 or 6 gear and going 10-15 miles per hour and no acceleration despite gas peddle pressed to the floor. Highly dangerous delay in acceleration response like when cross traffic. This will get people killed. Dealer says is working as designed. But it a very dangerous design flaw then. I can slow from 40 mph to 10 mph and then apply full acceleration and there is no response from the vehicle for 3 second. Very repeatable. No acceleration despite gas peddle pressed to the floor.

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.

I reported an issue with my 2019 Acura Rdx, where if: Engine auto stop is enabled, and brake hold is enabled. On two occasions, the vehicle lurched forward while the brake hold is enabled this propelled me to the side of the intersection today, with a 2020 loaner, it happened again

Erratic display operation causes driver distraction problems and possible damage to car operation (transmission). As shown in attachments it displays system error. The infotainment system screen goes dark. Tire pressure displays false information. I have taken the vehicle to the dealer multiple times; each time the dealer says nothing wrong or they believe problem will be fix with the radio update. They constantly reset the vehicle and write on the report, no problems found. My opinion is that there is an incompatibility with the vehicle electronics and the display systems in the vehicle and the infotainment system that Acura is using to present vehicle data to the driver. Img_0807 shows the warning of low tire pressure when in fact all tires have correct pressure. Img_0802 shows system error when trying to access a radio station. Img_0801 shows the system requires an update but no dealer or service group has the update. I'm unable to show the blank or flickering display. This is dangerous because you can't tell if the vehicle is in comfort mode or sport or snow

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!

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.

Twice now under 5400 miles, while depressing gas peddle to pass on an interstate at around 70 mph, the car totally loses power and engine light comes on leaving us in a very unsafe position in the fast lane of travel. We barely avoided collisions making it to the shoulder. After restarting the car, the engine light is off and car appears to operated normally again. Acura could not find any codes in cpu and told us to bring it back if happens again. Opened a ticket on Acura's web site - no reply for nearly a week now.

While traveling cross country on the second day of travel I attempted to accelerate to pass a car at appx 75 mph and my car suddenly and rapidly started to decelerate. I noticed that the "check engine" light was on and I could only reach speeds of appx 40mph. Once I made it to the shoulder I turned the vehicle off and waited apprx 1 minute before restarting. After restarting, I preceded to complete the trip without further incident. I have not experienced this condition since the reported incident. I contacted my dealer and notified them of the event and they said they are not aware of this condition.

I know by now the public may realize all the issues surrounding the 2019 Rdx model. I purchased one three months ago. While there are a host of important issues/problems I have seen with the vehicle, all 'appear' to be software related, I would like to express my concern with one specific issue. The throttle is delayed when accelerating from a standstill up to 10 mph, but can also happen at higher speeds. This appears to be dependent on the RPM. This occurs in comfort and sport modes. The delay is one to two seconds. This delay is critical when say, taking a turn crossing traffic. Yes, there are many customers with the same problem. I see this as a safety issue, just as bad as, for example, brakes not actually being applied for 1 or two seconds after being physically applied, or maybe the clutch being delayed in a manual transmission by two seconds. This would never be acceptable in the marketplace, but yet somehow an automatic transmission is ok to be delayed. We Rdx owners have received a software update in February. I feel this is unacceptable. It appears the vehicle was not ready for production 2 years ago, and has yet to see critical problems fixed. I have been to the dealer where they did a clutch procedure and passed on results to Acura. This procedure did not fix the issue, and I have passed this info onto the dealer.

Vehicle loses almost all engine power under hard acceleration. This fault requires you to stop the vehicle and restart to continue. Engine light flashes yellow. The first time this occurred was at highway speed in a passing situation. The second time was during a freeway merge. Both instances could have ended badly as the freeways were busy and other vehicles around me were traveling at speed. The first incident was reported to the dealership and to Acura corporate. Nothing was noted as faulty or corrected.

The engine shut down in the middle of an intersection in traffic, while in motion. The car refused to start up again, indicating a transmission failure. The car also refused to shut down, and the electronics are confused. This is the third incident that I had with this vehicle.
