My Cobalt Experience, '07 LS
I bought it new in '07 and so far I've gotten 78000 miles. It's a stick and I've really liked it; it's both stylish and practical. The only problem is, the entire front end is horrible. I wasn't gonna whine about it, but the calipers were the last straw. Here's the list of items that broke/leaked/tore:
1) Original tires went bald at 25000 miles. That's understandable, can't expect an entry-level car to have great tires. Turned me off to the tire brand, though...
2) Front rotors warped almost right off the dealer lot. Didn't want to bother with dealer hassle so I replaced them with wagner thermoquiet rotors & pads and never had a problem since.
3) Struts & shocks went bad shortly thereafter. Replaced with KYB's and enjoy a very stiff ride since then, no leakage.
4) Lower control arm bushing. By now I figured everything else OEM on the front end will fail anyway, so the entire control arm was replaced with Moog problem solvers, greased the zerks and no problems since.
5) Steering wobbled a lot, probably shaken apart by the warped rotors but who knows. Replaced the entire rack & pinion with A1cardone refurb. and the outer tie rods with new Moog problem solvers. Greased the zerks and the steering became solid again.
6) Started getting paranoid about the front end, so I replaced the swaybar links and bushings with Moog. Again greased the zerks.
7) While bleeding the front brakes and replacing the front hydraulic hoses this month (damaged during one of the many previous repairs) both of the original caliper bleeder valves tore off, flush with the caliper. Figured the calipers were probably failing so I replaced them with Raybestos remanuf. Been great so far.
I guess my advice would be to get ready for front-end repairs if you've got an LS. I still like the car, the mileage is over 40mpg on the highway. The vast majority of driving was highway, too. Glad I could vent here, thanks.
