2025 Acura MDX will turn off with the auto on/off feature at red light but has had issue several times with turning back on. The car turns completely off and have to push start button to turn back on. On one occasion the same issue happened but would not immediately start with the push start again.

Brakes are too soft . Hard to bring the car to a halt without crashing unless you are at very long distance . Brakes engage at a very low level . Dealer says everything is OK and can't do anything about it . Car is dangerous to drive.

The dealer and Acura has refused to repair since they have not been able to duplicate the issue. They wanted me to lend my new $60,000 car to their service technician to drive back and forth from home/work to see if they can duplicate the issue. The dealer has tested the battery, however it passes. They refuse to do anything with the starter or other components of the system whether it be replace or inspect them. As the car ages (now approx. 1.5 years) it seems to occur increasingly often. I am concerned that the Auto Star/Stop system is doing irreparable damage to the engine & transmission. Additionally, sometimes the engine gets cut off and...

My Vehicle is having an issue with the idle stop feature. Multiple times when stopped at a red light or when idle the car stops and will not turn back on. I have to turn the car off completely open the door to simulate leaving the car, wait a minute then start the car again to be able to move.
