Control Arm Fell Out...
Recently, I had noticed something wrong (other than clunking over bumps/ sometimes when the clutch is engaged/disengaged, which I've been procrastinating on getting fixed, think it's a motor mount) with the car (a 2010 XFE coupe); it was wandering all over the road and eating the front tires (assumed it was a toasted tie rod end, as a friend's car behaved in a similar manner with that problem), was going to get the car into the dealership (it's still under warranty, 30K miles) this week, as soon as I had the clutch replaced on my junker Honda (I deliver pizza, so I have to have a car to work.) and get it back on the road. At work today, while pulling out of the parking lot, I heard a particularly nasty clunk; the left lower control arm fell out of the hub, ball joint and all, immobilizing the car. I'm lucky this didn't happen while I was on the road, hate to imagine what would've happened had it failed while I was on the interstate (just finished quite a bit of holiday travel).
Anyone have an idea as to why this would happen/what broke in particular? I didn't hit a curb or anything that would have me expecting such a catastrophic failure (it broke while making a right turn).
Also, the tow truck sent by GM roadside assistance was straight out of Deliverance (and took three hours to arrive). The idiot driver managed to rip the CV axle out of the transmission and break heaven knows what else getting the car onto the truck, dragging the broken wheel on the ground rather than jacking it up and putting it on a dolly (which he didn't have, seems captain obvious to me). Who's going to wind up footing the bill for that?
I know that GM can make decent vehicles. The Trailblazer traded in on this vehicle was quite reliable (other than eating fan clutches like clockwork every 36K miles). I've not had good luck with this car, however. The lock cylinder failed at 5K miles (not a huge deal, was replaced under warranty), the clutch master cylinder at 21K (after being replaced, the slave failed on the dealer, soaking the clutch disc with oil, so I wound up getting a new clutch, more or less; this is also when the clunking began, though it was barely noticeable at the time), and now this. I'm probably not the kindest owner, as I deliver pizza with the car (when the Honda is unavailable/out of commission), but I don't beat on the car, race it or the like, and the thing seems to be falling apart on me. This is the second time in 4 months I've been stranded and forced to have it towed (both times at work, to boot), something that never happened in three years of driving a beater, whose only expensive failure has been the clutch, which is understandable at 267K miles. Additionally, my mother/stepfather purchased the car (I didn't ask for it, didn't want a new car, but I appreciate their generosity.), so I get screamed at every time something goes wrong. Needless to say, this is rather stressful. So, any ideas as to how to avoid having the suspension fall apart?
