Just brought my Lucern home from the dealer. Needs a new lane departure module. This would be the second one. First one was done under warranty. At $700.00 they can shove this technology where the sun don't shine. Why does GM keep making this crap that does not work. Oh by the way, at the same time have been diagnosed with an oil leak at the valve covers. That is only $585.00 to fix. Another common North Star engine problem. Just out of warranty at 70,000 miles.
