Purchased 1st Titan in Nov 2010 with 30,000 miles, it's an 08. I have a vibration around 45 mph. Tried balancing wheels/tires - even changed wheels and tires. Dealership said it was an inherent problem with the torque converter on 08 Titans and could not be fixed. Anybody else with this problem? If so, what did you do? I am at a loss. I like the vehicle and cannot accept that every 08 Titan has this issue.
