Carrier/rack problems of the 2015 GMC Yukon

On July 13 of 2018 ac in my vehicle started to blow hot air, I was with my 3 year old, during this day it was 98 degrees out, my husband took the car to repair shop and they found a leak in the condenser, apperantly this is a known problem for many gm vehicle with 5. 3 l v8 engine from 2014 and up, when we called local gm dealers they were aware of the ac problems on these cars, we were told that ac lines develop a crack and freon leaks or ac condenser starts leaking freon and in our case it's a condenser, after doing a research on the internet and reading on the gm forums many owners have these leaks due to bad design of ac components, it's obvious that gm should issue s recall because too many vehicles have same issue, and since our warranty has expired 6,000 miles ago we have to pay over $1000 for a repair, I hope your organization will do something about this problem, this should be a call for a recall.

Vehicle has a terrible vibration. Has been to dealer 7 times, for a total of 4 weeks. A gm engineer has looked at it twice. They have replaced ring/pinion, driveshaft, axle . . Tried it with 4 sets of tires/wheels. Last idea was to replace shocks, struts, sway bars with hand built parts, cut brackets off car and weld new brackets on. When liability was brought up, they changed their story. There is a larger issue as was relayed by engineer to service manager at dealership. Issue is with all 2015 tahoe, Yukon, escalades. In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board. According to engineer, gm is keeping an eye on how many units they have to buy back, or trade for . . . If number is low enough, they will not make any changes to design. I would like to schedule a meeting next week to discuss this issue and the larger issue in person. Since they are refusing to buy back my vehicle, I am turning matter over to attorney.
