2017 GMC Yukon

First problem started back in May.. it’s went downhill ever since. Hard shifting was happening. GM dealer said I needed a new transmission. Found out from local repair shop that I needed a torque converter ($600) multiple transmission fluid changes (apparently many issues for A Lot of people) changed that. Then had to change Valve Body & TCM. ($540) everything started working but not 100% did a full tune up having multiple misfires constantly then shuttering when idle. Also replaced ECM ($200+)After changing all spark plugs, wires, oil, etc. the AC was having issues had been having issues for months. Kept adding Freon had to replace AC Condenser (works great now, was told by repair shop that’s also very common in these year models. Condensers are all weak in the same spot) just recently October 2022, my instrument cluster started going haywire. Gauges going off and on screens going blank. Had Alternator and battery tested both test fine. No loss of power but when hitting the start/stop vehicle would continue to run and lock and unlock when it wanted. Husband took the alternator out to have it tested again. They tested 3x 1st. Good, 2nd Error, 3rd Bad ( it was overcharging at 16.5V) replaced Alternator ($290) gauges still going haywire, like before it is only sometimes, when they do it’s bad bad.. but I can also drive to town and back 20-30 miles and not the first issue. Just left GM with a new Battery Distribution Fuse Block ($153) because of course it can’t just be a regular ($8-10) mega fuse, hopefully this will fix my issue. We pay too much money for this vehicle to have all of these issues & none be under warranty. I’ve been having the TAILLIGHT ISSUES as well ever since I purchased the car in 2018. When I received the recall on the taillight it was 6 years up to 72,000 & of course my vehicle had 79k miles on it at that time so that’s wasn’t covered.

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

My vehicle began shuddering during acceleration and would violently jerk forward after gas pedal was engaged with decreased power in forward acceleration and increase in rpm. This last a couple of weeks. Now, my vehicle is completely broke down and at a GM certified service center. The Service manager states torque converter completely went out and the transmission is burnt up. The mileage is at $61,000, so GM warranty won’t cover it and the company that holds the extended warranty I purchased hasn’t been able to be successfully contacted. There is a “service” bulletin but no recalls and a class action lawsuit (that I’m not a part of) but no recall. My vehicle completely lost power going 50mph on a busy road without warning. This needs to be a recall due to this dangerous circumstance.
