The engine will never go into 9th gear! What's the point of GMC doing a 9 gear transmission to help with fuel, if it never actually goes into the 9th gear?

SERVICE BRAKES
We were in the driveway thru lane at a fast food restaurant and all of a sudden the car shut off and the brakes got hard to push in. The car was able to be started at this time but the engine wasn’t working well. We were able to make it home, slowly and carefully. We had the vehicle towed to a Mechanic and this is what was told to us: Possible increased brake pedal effort due to mechanical engine vacuum pump failure. We had it sent to David's Auto Service 219-861-0666. This could’ve been a very dangerous accident if we were driving on the expressway or on a regular street going the normal speed limit. Thankfully we were in a drive thru lane.

ENGINE
My vehicle had lack of engine excelleration, hesitated and was hard to drive. Took it to the GMC dealership and was told it was the timing chains. Because this was my only car and needed transportation for work I had it repaired. The amount was an expensive repair of $2,219.71 for what I researched was something that was happening in many of the 2015 GMC Terrains. People have been trying to get a recall notice to be sent to owners because it is so common and dangerous. I could be out on a busy highway and having the car die on me. Is there a way to receive some compensation for this seeming to be a normal problem for these cars. Why is there no recall especially since it has happened in many many of these 2015 GMC vehicles

SERVICE BRAKES
After driving down around 40 miles, the brakes failed when pulling into a parking spot. There was no indication that the brakes were having issues. No sounds or vibrations were felt. I stopped at a stoplight before turning into the parking lot. Then when attempting to spot in a parking spot, the brakes were very difficult to press. Luckily there was not a vehicle or person in front of me. Had the vehicle taken to a dealer and was told it was the vacuum booster that failed. Upon researching, this has been an issue in past GMC models, but I was told there was no current recall for the vehicle. The vacuum booster was replaced for $540 and I drove the vehicle home. The vehicle showed no issues for the first day. On the second day, I went to pull into a parking spot at a park and the same issue with the brakes occurred. I nearly struck a child that was walking in front of the parking spot. Luckily I was able to slam the pedal to the floor and come to a stop. Took the vehicle to the mechanic and was told the same part had broke. That part has been fixed again and has been fine for 2 days so far. I'm scared that it will happen again and I will not be able to stop in time before I hurt someone else or my family. This needs to be addressed. And I believe I am owed compensation from the manufacturer.

POWER TRAIN
Have a 2014 GMC Terrain SLT AWD. Just rolled 81,000 miles. Heard some catching in what I thought was front left tire while turning right. Almost sounded like wire wrapped up. Looked under car didn’t see anything. Continued to drive and began to hear really loud grinding noise. Could smell the car getting hot. Get it to body shop and they have identified the transfer case was blown out for unknown reason. No fluid and gears are just walking around. Caught it before it locked up. Needs new transfer case, when we can even get one. Looking at about $2500 in repairs. Of course just out of extended warranty. This appears to be a common problem and needs to be addressed by GM!
