I purchased a 2017 GMC Yukon Denali brand new off the showroom floor. I have maintained the services thru GMC dealership. I had to replace the struts and rear and front shocks due to hydraulic system leaking and locking up my brakes and causing extra pressure on my braking system to stop my vehicle. This cost me over $5000 to replace out of my pocket and I saw there was a previous recall in 2019 for similar problem but i was told my issues were not covered under the recall. I have also had to replace both taillights within 2years of purchasing my brand new vehicle and now they are out again. This will be my second time having to replace the LED tail lights that cost over $375 light which were stated as never go out of lifetime guarantee. You cannot just replace the bulb you have to replace the whole tail light which takes weeks to come in and then additional labor costs. The previous

There is a known issue with the GMC strutts leaking. I contacted several GMC dealerships to purchase strutts so that a local mechanic could put fix my truck without the dealership pricing. GMC refuses to sell the parts to anyone other than a dealership. I was informed by several dealerships the part is a national back order for 6 months. The cost that GM is making for each person that purchased a 2017 Denali is between two to four thousand dollars!! While driving my truck myself and my daughter would come out of the seat! This should be a recall. I'm also reporting this to the consumer financial protection bureau. I phoned this in a month ago and have heard nothing.

Front magnetic shocks quickly failed, part no. SK3354. Part has been on backorder for over a month, which means it is failing on many vehicles. Part is known by repair shops to be defective, but they say the replacement part lasts longer. GM should pay something toward replacing this defective part, which is on many of their vehicles. Failure of this part causes vehicle to bounce excessively which makes the vehicle more difficult to control.
