Maybe they scewed with it. I once took the car to the dealer to have the trx and the coolant fluids flushed. The steering was fine when I took it in. The next day, steering was off. Were talking off like steering wheel went from 12 o'clock to one o'clock just to keep straight. Explanation... Well it pulls to the side because the road is not flat, especially the road right here by our dealership! You need an alignment. Ka-ching. $95.00 Needless to say, I never went back there, nor did I get it aligned there. (It's not like I havn't been driving my car for last 125.000 miles, and don't know when the steering has been F$%@#ed with.
Finding an honest good tech are far and few between...
