I got a 2014 altima s and the trip meter resets itself every few weeks. Not my car and it isn't driven consistently so not sure when it happens. Any ideas?

Sounds like the battery is going low enough after sitting for the cluster to lose its memory. A healthy '14 will draw about 15 milliamps off the battery even in hibernation, so even with a new battery they can't sit more than a few weeks without significant voltage drop. If cranking then takes the battery below about 7V, the cluster will lose all of its "RAM-stored" data. See if the other info items like fuel mileage are also disappearing. If so, then it's probably a low-voltage issue. Other than a stronger battery, there isn't really a good fix for it besides keeping a float charger on the car whenever it will sit for awhile. For the dealer lot they provide us a "storage fuse" that limits unnecessary drain until the car is ready to be sold, but that won't solve your issue because the cluster backup is on the storage fuse. You'll simply make the problem happen every time you park it.
