Mid/rear Seats Assembly problems of the 1998 Chevrolet Blazer

At the time of purchase the dealer could not get both sides of the back seats to lay flat only the right side. Another complaint is I took my vehicle to the shop because it sounded like the right front tire was warped and when the mechanic did the diagnosis of the front the hub assembly had to be replaced. I was wondering if any complaints have been made or is there pending recalls for these.

Driver's rear seat adjustment broke 3 times, and caused seat to move to an uprigtht position. Therfore the driver is not able to adjust seat back for suitable driving position. Chevrolet cannot determine cause.
