I don't think there's a manufacturer out there who doesn't produce a problem gun from time to time.
Kimbers are popular, and so they get mentioned more often--for good or for bad. It's like Harley Davidson: they produce more motorcycles than BMW, and get criticized more often. Go to a BMW rally, though, and you'll hear tons of complaints.
I'd put thousands of rounds through my Pro Carry (bought in 1999) before I realized I had a problem. That was while taking a two-day course in July 2002 in 90-degree heat, with over 500 rounds fired. Gun oil isn't up to that task. Use something heavier, like Tetra Lube.
The slide stop got bunged up and I had the slide not locking back after the last round. I managed to get a Wilson "Bulletproof" slide stop on the first night, but it didn't do any better. In fact, I wound up going back to the Kimber slide stop and made a point to count my shots.
I dropped the pistol a couple of years ago and really messed up some internal parts.
Whether you buy a Kimber, a Springfield, a Colt, or even a Charles Daly, there's a few things you should do.
Make sure the extractor is working properly. 1911Tuner can tell you in more detail how to do this (or you can search for his posts). Basically, chamber a round, drop the magazine, then pull the slide back slowly. The extractor should be gripping the case and pulling it to the ejection port.
Keep it properly lubed. I really learned my lesson on that one.
Put hundreds and hundreds of rounds through it before you trust it.
If you choose to keep the factory MIM slide stop, inspect it with a magnifier every time you clean it, looking for any gouges.
Don't use the Kimber mags. Some say to use Wilson mags, others favor MecGar, Shooting Star, other mags. The Kimber mags are a crap shoot, and I don't understand why they still ship them. On the other hand, Colt mags don't work at all in my Pro Carry, so
for Colt.
Once the gunsmith finished repairing all the damage I'd done by dropping the pistol, it functioned 100%. I tried to get it to fail, but couldn't.
Or get yourself a good revolver. I shot thousands of rounds in IPSC competition years back, and only had one problem: a handloaded round (my handload) with no powder. Bullet stuck in the barrel. If it had been a defensive situation, I would have had a shiney blued club.
