Suspension Problems of Buick Park Avenue

Driving down the hiway, had just passed a semi; thank goodness it was after that that my driver's side tire blew making the car quite difficult to steer. Took it to firestone; had to have both front tires replaced and instructed to bring it back the week after for an alignment. At that time I discovered that both new front tires were already ruined due to the cradle/frame assembly which was rusted out. This cost me $863. Yesterday - 08/12/2015 the fuel pressure regulator went out. Upon my investigation I discovered this was a recall issue. I was told it had been fixed. . Altho there wasn't any concrete proof given to me that it had as the dealership I called was not the dealership that said the issue was resolved. Now I have a car that is completely inoperable just weeks after spending $863 to have one issue resolved. I find it particularly appalling that no one seems to want to help resolve any of these issues.

My issue is constant vibration of the vehicle at highway speeds. I have replaced all tires, all struts, balanced numerous times. Buick people tell me its the tires. Tire people tell me its the drive train. Meanwhile, nothing gets done except I keep spending money. I don't mind a problem now and then as long as someone responds to it. But in this case, based on my own experience and reading accounts of other owners, this issue never goes away. My guess is now that I'm out of warranty, gm will be more than happy to stick it on the rack at the going labor rate and maybe get to the bottom of it. I see TSB 833004, which I just discovered, was published in 9/98, long before I went into sun Buick with this issue, but they never mentioned or did any of the remediation called for in that TSB. What other buttons are there for a consumer to push?.
