Software Problems of Acura TLX

On the interstate going 75 mph, cars throws itself into neutral and completely loses power. Warning lights come on saying there is a problem with the transmission, electric brake, and emission system. Car coast to the side of the road and is completely dead, but dashboard lights are on. Car is locked in neutral and cannot be shifted. Sat waiting for a tow for 30 minutes, cars can now be turned off, then restarted and suddenly it can be driven again. Very dangerous and I was not happy with dealers explanation as to what caused problem. First they said it fuel pump, then a software issue. Since I brought it to dealer, transmission now does not seem to shift properly, its very jerky. The car is very dangerous to take on the interstate. This all happened when it was 90 degrees outside, a very hot day.

Again, while driving approximately 75 mph on interstate all error codes on dashboard (mil) lit up and the car began to feel as if the transmission was not engaged as if I was in neutral and the engine began loosing power. The speed began decreasing, but then would catch for a few seconds. The gear indicated that it was in drive. I pulled off the interstate & parked. I waited a few minutes & restarted and tried to re-engage in drive to see if it reset itself as it has done in the past just 7 weeks prior, however it just revved up. I called road side assistance and had it towed to nearest dealer an hour away as again the mechanical break down occurred while I was traveling in between cities. The next morning, the dealer was able to retrieve the error codes and said that the transmission needed another software update to repair the issue, the computer was reset . While driving home the transmission became jumpy again around 3rd gear. I contacted my local dealership and made them aware of my safety concerns for the car as again, my entire family (husband, kids and dogs) were in the car and felt as if this could have resulted in horrible accident had I not safely navigated off of the interstate while at such a high speed with heavy holiday traffic. This error has displayed for times and each time there was a different solution to the problem besides having 2 transmission updates, bad battery cell and replaced push button gear assembly. I have documented all incidents and reported to dealership as well as Acura corporate. I currently have appointment for next week so that their service adviser can try and replicate this intermittent problem to determine what the error is. I've made them aware that this is a dangerous mechanical issue that not only puts me and my passengers in danger but possibly other cars, but was assured I do not need a rental until it can be seen again.
