Front CV should not be engaged in 2wd.
If it's an automatic transmission it very well could be the torque converter.
Take it to the dealer (if possible, the one you bought it from) tell them the issue and have they verify that the transmission fluid level is correct.
Make sure they document the issue.
If it happens again or happens during driving let the dealer know immediately, there has been SOME problems with the torque converter but usually occurs when accelerating. Could be related or could just be low fluid level.
