I bought my Cobalt with 100,000 miles on it, so I was expecting it to need some work at sometime or another, and maybe have a leak here or there, but it simply hasn't been the case. I change my own oil and always do a look around underneath the car to check for issues, and I almost always come up empty handed. I now have 157,000 miles on the car, and all I've had to change are the brakes, tires, and a couple control arm bushings. The reliability has been phenomenal. About the only gripe I have is that the interior is very basic and cheap looking
I have to say my Cobalt has been a pretty good car in terms of reliability. There's been a few problems but I've had most of them were fixed by my local dealership. At 23,000 miles my power steering pump quit while merging on the interstate, lol wonderful right? (Replaced under warranty) At 51,000 miles my radio would randomly turn off and start working again when it wanted to. (Replaced by GM under warranty) And my door speakers would only work when it's warm outside. (I just had new ones installed from Best Buy.) But besides these things the car has been great. It's fun to drive and has a lot of pep for a 4 cylinder. It's great on trips and I plan to have it for many years to come.
Third review from me on my '08 Cobalt base LS w/automatic. Most owners probably either sell or trade 2 yr old cars nowadays. Which is my reason for a 3rd review. Since buying this in Jan of '08, we've seen Toyota go through their inevitable fall from grace, and Honda's numbers are down as well - no doubt due to lack of interest from generation X, Y, or is it Z by now? Either way, once we have all small cars starting to look like Scions or Mazdas, I'd swear it's starting to look like a science fiction movie version of The Stepford Wives - only done in a small car theme! ;~0 . Anyway, I still have my '08 white Cobalt with nifty round red taillights and it still purrs along nicely!
I bought this car back in September w/ 40,000miles. Every month starting a week after I bought it, it flashed "low engine power," I went from going 70mph on the free way with my speed dropping dramatically when I was in front of a semi truck. I've taken it in about 8x for this problem, 5 different part have been put in yet low engine power keeps coming up at the worst times. I'm scared to even drive my car. My car keeps telling me to check my air bags yet when I take it in there fine. Three different shops and the chevy dealer to looked at my car. Its a money pit. I'm now having to trade it in take a loss and buy a new car. But I feel karma will come back at me when someone else buys it.
We bought our Cobalt new in 2008. Got a great deal & are very happy. We had one thing wrong with the mirrors when we first got it but taken care of quick and easy. Our cobalt is a manual & we get about 34-37 mpg on the highway, 30-33 in city. (depending on who is driving). Overall a good car, just not a lot of room in the back seat.
