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.

After apple's ios update for iphone, apple carplay has become unstable and crashes for no apparent reason resulting in active navigation services while driving, becoming unusable without warning. Restarting the Acura technology and/or the iphone results in continued sporadic but unuseable operation. This can result in severe driver distraction and lead to collisions resulting in injury or death to the vehicle occupants. Acura has indicated to me that they have received a number of complaints of this nature and is looking into it. Calls to apple support have resulted in an attitude of indifference and attempts to attribute the issue to Acura & google. Apple's current response is to send an email to feedback@apple.com. The response I am seeking is to require apple/Acura to inform Acura customers that carplay is currently experiences issue and may unexpectedly cease operation while in use and advise customers to refrain from using it until the issue is remedied in order to avoid driver distraction resulting in possible collisions. Additionally I would like to see apple & Acura setup special email addresses for owners to report carplay and technology anomalies, with a tracking system in place to research, address the issues, and expedite the resolution of them.

Voice recognition with apple carplay and 3rd party apps fails to function which can lead to driver distraction resulting in collisions. This is an apple issue, not an Acura issue. Third party apps for apple carplay have been released several weeks ago from this date but voice recognition will not work with them, at least in the 2019 Acura Rdx (listed as compatible) and most likely all vehicles that do not have touchscreens. I have done exhaustive testing on this issue and reported it to the highest levels of apple that applecare will allow me to go but I get 'stonewalled' about this with apple claiming it is a problem with google maps and waze, not carplay. However both apps use the the same gui which sends me a message that it is an issue with the carplay software library, not the 3rd party apps. However apple refuses to acknowledge this or give a high priority to resolving it. I am of the opinion it is a serious safety issue as it can lead to driver distraction resulting in accidents and possible injury or death. I have suggested to apple, and google that the apps be disabled in carplay until this issue is resolved but have failed to receive any acknowledgement to this suggestion. Extensive documentation of apple's refusal to acknowledge this issue is available upon request. This has been an issue for many weeks now. With the latest attempt on the date below. Google, creator of the current 3rd party apps has also been informed with no response.

The electronics on the vehicle - the phone, navigation system, radio - freeze up and won't function. The navigation system's keypad doesn't work. Apparently this is now a frequent problem on 2019 Acura Rdx's
