NHTSA Complaint #11613936 — 2015 GMC YUKON

My vehicle is currently in the shop getting the motor worked on for a bad lifter. From the information the mechanic provided me this is a common issue with the vehicles that have the Active Fuel Management system. They are seeing many of these vehicles have to come in and have very expensive repairs. My first quote I received was $16, 000, they told me I needed a whole new motor and this assessment cost me $365 and a rental car while they looked at the truck. Now it is in the shop again and the estimate is $6000 to machine the cams as there are metal shavings in my oil. I had to again rent a rental vehicle and have not had my truck for a week. This is the third mechanic that has seen multiple of these motors have to be replaced or repaired due to this issue. I kept up on my oil changes and other recommended car maintenance and so did the owner before me. I had my last oil change approx. a week before the loud ticking noise began, then my vehicle began to have a noticeable loss of power when driving and eventually began shuttering and my check engine light began to blink and I took it to the shop. A year ago I had to replace my tail lights. I was able to find where others were recalled by my VIN for some reason was not included in the recall. They started shorting out and working only part of the time which is very dangerous when stopping, especially at night. I had them replaced and paid almost $700 for the two back lights.
