The push button ignition switch was accidentally pushed, very briefly, while the car was still moving, with the gear shift in still in drive mode, the engine shut off. This could result in serious injuries or even death if the car abruptly changed speed, loss power to other safety control systems, loss power to the airbags, or loss power to the brakes.

The contact owns a 2014 Acura MDX. The contact stated the back-up camera intermittently remained activated while driving. The contact took the vehicle to the dealer, who was unable to provide a diagnosis. The dealer refereed the contact to the manufacturer, who offered to further investigate the failure and other alternatives. The vehicle was not repaired. The approximate failure mileage was 200.

Brake pedal gets really stiffen up and car won't start unless I depress the brake really really hard. Seems like faulty brake system. This happens when the vehicle has been left sitting for awhile. Happening frequently now.

The included infotainment system, which is now predominantly controlled by a touchscreen, is incredibly slow, laggy, and dangerous to operate. There are multiple, ongoing failures with this system - every time I enter the vehicle. As Honda/Acura has removed or replaced primary-operation buttons (32 out of 41, by their count), the mandate to use the other operational system (touchscreen and jog-dial) has increased the risk of safety incidents, exacerbated by a slow user interface response and often-failing voice control system. My vehicle has been in the dealer once, and has been waiting for a software update for five months. New vehicles have an updated software load, but Acura refuses to install it. Acura client relations has refused to provide updates or a solution.

My brand new MDX has had issues with multiple warning lights appearing on the vehicle when starting the engine. This includes check engine warning, lane departure warning failure, power steering issue and possibly additional warnings. The vehicle did this the first time when I took delivery of the vehicle and at that time, was resolved by fixing a loose plug. Then it did it again when I was supposed to pick up my vehicle for a couple minor trim repairs Saturday, December 7, 2014. The vehicle is still with service and they have yet to figure out what is causing the warning light issue. I was advised that they are in touch with Acura's tech line on this and they hope it will be resolved soon. Additionally, I completed further research on this and noted that other owners are experiencing similar problems with warning lights appearing on their 2014 MDX vehicles. Here is an online reference that I found where owners have posted comments on this: www.mdxers.org/forums/94-new-2014-Acura-MDX/63666-2014-MDX-issues.html.
