This car has been nothing but problems in the last year. This is the latest, most serious and most expensive problem thus far. I will fill you in about the AC, Rear struts/shocks, Taillights and transmission issues on another complaint. Unfortunately, this issue happened at the worse time while taking my son to JFK. The Yukon was running fine and then all at once there was shuttering, rough idle and a small knocking noise. Which then kicked on the check engine light. Pulled over instantly didn't sound good but I didn't have time to tow to shop, had to make a flight. I had to push car over to another parking lot because gas station I stopped at wanted to charge me $200 just to leave for a couple hours until tow came. After an uber and renting a car to continue to JFK. I had to call a tow truck. Uber $45, Car rental $240, Tow $500 (didn't have AAA at the time).

While at mechanic shop they found roller in lifter stuck and destroyed camshaft. Had to pull engine to replace camshaft, lifters, de-activation solenoid. I ended up getting lifters on both sides done didn't want to ever be stuck in this situation again. The worst part is that I still have payments on this stupid car because I overpaid during COVID car shortage days. I'm having total trust issues with this vehicle since it was well maintained and only has 67K on it now. I can't believe the headaches with this car. The money spent to fix all the issues and time without a car for the repairs. My husband refuses to let me buy another Chevy product after this I can't say I blame him. Had a 2008 Tahoe LTZ before the lifters went bad at 120-130k but besides that never any major issue with it. The deactivation technology AFM & DFM is a downfall of the once reliable engine the Chevy once had. Unfortunately, Chevy doesn't own up to the issue or even recall or reimburse which is sad to say as a long-time consumer of Chevy.

After keeping up as scheduled with normal maintenance on my Yukon, after my last oil change I starting hearing a loud ticking sound when I started it up one day. I took it in and had it looked at and the facility gave me a quote of almost $15000. I had to rent a car for them to take the time to look at it. This quote was way to high as they wanted to install whole new motor so as I continued to look for another shop, the sound grew quieter but my truck had a noticeable reduction in power. My check engine light began to blink and I took it to the shop for repair, it is in the shop now with estimated repairs near $7000. After reading all the other vehicle owners with this issue it is astonishing how there has not been a recall. This is a very expensive fix for a vehicle I still owe $20000 on and trading it in is not an option due to amount I am upside down. The 3 mechanics I had look at it said this is becoming a increasing issue they are seeing with the active fuel management system motors.

$7042 was the cost charged by the dealer to fix the lifter problem. When I brought it in, there was just a small noise that had just started. The service rep made it sound like the car wasn't going to be drivable for long. They made it sound like I would be totally irresponsible if I didn't get it fixed right away. Then they told me once the lifters break, they will do the same thing again.

They charged me almost half the value of the vehicle to fix it! If this happens to a whole list of vehicles (according to the dealer) why didn't GMC recall the vehicles and fix it? Well, I was told they do not have a permanent fix which is why it will happen again and they can't recall the vehicles and fix them permanently.

This is crazy! How do we know the newer models will work properly? My vehicle was maintained - never missing a scheduled service - by the dealer. Now I heard from another dealer that the problem is caused by poor maintenance running bad/dirty oil etc. They really just don't seem to know.

SOOOOOO, to keep my vehicle, I paid $7042j once - and do I just WAIT to do it again? SO FRUSTTRATNG!!!!
