My truck is just out of warranty, but after 3 years only 15,000 miles. Chk engine light comes on, dealer says 3 bad fuel injectors. Dealer has several other trucks with the same problem. Obviously a manufacture problem that I shouldn't have to pay for. Also is this an emission system problem?

On May 26, 2020, my 2017 truck's check engine light appeared. Vehicle is in original manufacturer's warranty with 25,000 miles, + or -. truck driven infrequently during "stay-at-home period. Took to GMC dealer immediately; read code; indicates all 8 fuel injectors out of tolerance.can't explain why or provide impact to vehicle if driven in this condition. Can't be driven; dealer provided loaner. Can't advise if vehicle's engine will cut-of if driven causing unknown issues. Fuel injectors are on back order-no estimate of receipt date! another 2017 GMC truck there with same issue-been there for longer period. GM will not advise dealer when fuel injectors will be received. Delay possibly associated with GM strike or virus. If two or more vehicles have problem, is pattern or practice-a systemic issue. GM customer assistance can not provide information. Difficult to contact GM corporate offices for assistance. Today is three weeks without my vehicle, which I need. GM is not providing adequate (any) information to its dealer. This out of tolerance fuel injector situation has been noted on GM owner websites; it is not unusual.
The same issue as GM service bulletin pi1513F (radiator leak) has happened on my 2017 GMC Sierra. This service bulletin currently covers 2014 - 2016 models and needs to be extended to cover 2017 models (and possibly 2018). This issue is a radiator that leaks on the passenger or drivers side on the wall between the cooling fins and the end of the radiator.
Our truck is less than three years old with approximately 69000 miles. The transmission just started slipping out of the blue while driving thru a neighborhood. While in drive it would move but once accelerating it would rev up and not change gears. This happened without warning, without an engine or warning light. We do all the necessary regular maintenance. In addition two years ago while the truck was a year old, the brakes went out while driving on the interstate. I guess it was the brake vacuum pump or whatever that didn't allow the brake peddle to be pressed which provided me with no brakes. Again with absolutely no warning! this later became recall issue but not before it had already happened to me! I understand there is a class action law suit against GMC for transmission problems and I would consider being a part of this. This is a 50;000$ and relatively new truck, this is unacceptable! the dealer now wants over 4000$ for repairs.
My radiator has developed a leak and coolant is escaping when engine is hot. The issue appears to be very similar to the incidents with the 2014-15 model year issue. The problem was diagnosed to be a leaking radiator near the top right side by an independent mechanic.
The vehicle was purchased in January 2017, since the purchase of the vehicle, I have had the truck in the shop on 6 occasions. The vehicle has had 5 injectors replaced and the upper oil pan gasket has been replaced twice. GMC is stalling me and not wanting to purchase the vehicle back under the buy back program commonly called the lemon law. The vehicle has an extended warranty and I have been charged a co-pay with the repairs on the vehicle. The issues started after the 30000 mile service.
1. the transmission shifts extremely rough from 1st to 2nd gear in parking lots at a slow speed and on normal highway or street driving and experiences the same thing while slowing down to stop 2. the engine has recently been having a awkward shake to it while in ideal after it has been running and warm 3. while backing up and turning the wheel, the front suspension will let out a loud clunk sound and the sound will return when turning the wheels back forward after putting it into drive.
The vehicle which has under seven hundred miles on it does the following: When I try to accelerate the vehicle starts to misfire, starts to chug and jerk, it starts to hesitate and becomes rough. When I called GMC service department I was told there was a code for this problem #pip5457B but that currently there is no known reason and no known repair and no known computer code to repair the problem. I tried to merge onto the interstate highway and needed to speed up but the truck started to lurch; I nearly got rear ended. I can't drive up a hill in the city or on the interstate and keep up with the flow of traffic because the transmission starts to sputter. My wife and I are afraid to drive this vehicle. We just paid nearly $49,000 for this GMC Sierra 2017 and only owned it for one week when this started to happen. It does this all the time. Very dangerous!
