I work in the Auto industry, and yep, the amount of code in a typical car is enormous.
Just do a simple, back of a envelope style calculation. A typical car has about 25 electronic modules, ranging from simple seat beat controllers and complex controllers like engine management units and instrument clusters. Assuming that each modules have about 250K line of code, that would take it up to 6.25M line of code. That goes up if we start to consider high end cars like BMWs and Mercs.
Let's not forget about the development infrastructure around the code development, that is another story..
