Transmission mount bolts have fallen out at least 3 times even though replaced with the correct bolts and correct loc-tite. When they fall out the drivetrain drops onto my steering assembly causing it to pull one direction or another or sometimes it feels like it wants to go left and right at the same time. Now my steering is messy even with tranny mount bolts installed the steering ass seems to have been 'stretched' causing it to pull both left and right at the same time or sometimes really hard to the right (tires seam to wear evenly -though it is hard to believe). Tire shop first thought it was ball joints but decided no bad ball joints. Also many times when I put the car up on ramps or a jack to change to my summer wheels or change oil the e-brake doesn't want to hold. I push the pedal to the floor and comes back up almost all the way. Only once or twice in the 12 months that I have owned the car has the e-brake held. Sometimes it will hold for a second or two but then it releases or 'slips'. These problems bother me especially after seeing the corrosion recall for other gm cars for problems like my drivetrain mount bolt holes corrosion problems.
