Check engine light.
I've had a few Blazers. The "check engine light" comes on on all years and models, and has to do with the oil. If you notice that when the engine is at more than "idle", it will turn off. In that case, there is no problem but a minor design flaw.
I've never had a problem in over 420,000 miles on 2 Blazers. Just keep the maintenance up.
Would you buy another car from this manufacturer? Don't Know
