A harsh engagement of the automatic transmission may be noted after the engine auto stops. A software update for the powertrain control module (PCM) / constantly variable transmission (CVT) is available which may correct this issue.

Now at 106 K and having a/c compressor issues and strong transmission noises. I hadn't linked the latter to the auto stop, but I've had problems with lack of engagement, unpredictable engagement, stalling, etc. with auto stop for years (since car was young) with no appropriate response from Honda (at 2 dealer service centers). They could not recreate the issue, but after many attempts, a tech. found a bad sensor, but it was never repaired. I find this very dangerous, as there are times when I cannot get the engine to reengage and I have no power. Dealer stated that I didn't use the auto stop properly and implied I didn't understand how it worked. I'm surprised there haven't been serious injuries from this.
