Chevrolet Suburban owners have reported 2 problems related to engine overheat (under the engine and engine cooling category). The most recently reported issues are listed below.
The coolant level in the reservoir continued to drop, prompting me to refill it weekly. Service shop worked on this on and off for several months. After several engine overheating situations, we took it to a different shop. Turns out our heads are cracked. They were manufactured by castech and are known to be defective according to gm bulletin #06-06-01-019b (document id 1986750). There is now so much anti-freeze in our engine that the entire motor needs to be replaced due to the corrosive nature of the fluid. Gm said that they would pay nothing towards our repair. The engine only has 91k miles and now needs total replacement b/c of an issue that gm knew about since 6/12/07 but never contacted us about. Had the replaced the heads back in 2007, we most certainly wouldn't be facing total motor replacement at this time.
