I have already replaced both the driver and passenger front door pull handles. According to my mechanic, it's a VERY common problem with the Tahoe/Yukon model. I want to say it was like $300 each door!!
We have had our Yukon Denali now for two and a half years and we're already on our second broken door handle. First one we had to have fixed at the dealership for $250 this next one will cost us about the same if we have it professionally fixed. Pretty obvious that the plastic door seal is very bad quality. The dealer told us that this is a common problem as well but that it was not covered by GM. Sounds like a defect to me!
Drivers door inside handle broke today 10/19/15 after it started acting up back in July of this year by not opening when pulled from inside.It would take about Two-Three tries before it would work & open the door!
We have had 2 handles break and we have had this car about 2 years now it is very evident that the quality of this car is in the engine and not the equipment ie the door handles and the buttons as well as the power running boards
