Our MDX has about 70,000 miles on it, and the battery has been replaced once about 3 years ago. Randomly, the nav will start cycling through various commands on it's own, seat Memory will no longer works. And worse, the transmission will start shifting abruptly and harshly--or not shifiing at all. Once you turn the car off and restart, everything will be fine for a while. Has anyone else had this problem? What could it be? Is it battery related?

Sometimes a bad ground cable can cause a lot of issues and since there is only 1 to the battery might as well check it out.

Implying that the ground to check is the main ground from the battery? Or should I check grounds/shorts around specific equipment?

Yep its a common issue it seems.. Its odd that this gen only used 1 single ground, bad hindsight if you ask me.. There should be at least 2 grounds to the battery (1 for chassis, 1 for trans).
