Cars are growing more and reliant on software for their basic functions, which, as cool as it is (see: the Tesla Model S), occasionally means bugs in the system.

General Motors is seeing that now with a recall of 33,700 of its 2013 Buick LaCrosse sedans and Cadillac SRX SUVs. Because of a glitch, the transmission may unintentionally shift from manual to automatic. Not the best thing to happen if you’re out on the road, although GM says no one’s been in a crash because of the problem.

About 27,000 were sold in the U.S., 1,300 in Canada, and the rest from Mexico, the Middle East, and China.

The good news about the problem, at least, is that it sounds like an easy fix: anyone driving one of these cars can stop by a dealership and get the software reprogrammed free of cost.
