STRUCTURE:BODY
This complaint is about the automatic extending/retracting foot steps on my GMC Sierra. The step is supposed to extend outwards when the door is opened and retract back under the truck when the door is closed. Instead, when the door is opened the step extends and at random will retract back inwards. Aside from being annoying this is actually dangerous as the other day i was exiting my truck with one foot on the step and the other reaching down to the ground when the step started retracting. The foot on the step was pulled under the truck and got stuck in the step. This threw me off balance and the other foot hit the ground at an angle and twisted my ankle. I called a local gmc dealership about it and they said they have seen a lot of trucks come in lately with the same issue and would have to replace the entire step for $1800. I brought it to an independent shop and they cleaned and greased the hinges so it happens less often now but it is still a problem. There are no warning lights or messages on the vehicle. It will also extend and retract at random when the truck is parked and off. This began happening around March of this year.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL
Transmission shifts hard and seemingly late and early (sometimes to the extent where it feels like someone is slamming into the vehicle). This has happened since purchase in 2019 ( when I told them about it them about it they tried to tell me it was normal and acted like I was a fool), continues to get worse especially in stop and go traffic at lower speeds, but does it at all different speeds.

SUSPENSION
With out any warning my right wheel had broken when I tried to drive from my dive way to work. Looks like Excessive wear to the front-upper control arm ball joints resulted in ball joint failure and wheel separation. Reported to a dealer. Waiting for the appointment to do full investigation. Separation of a front wheel while the vehicle is in motion increases the risk of a crash. I drive in city and highway roads, nothing rough. Very high risk for lots of lives!!!!!! People can die!!! Need immediate attention!!!! Please see https://www.consumeraffairs.com/recalls/fox-factory-recalls-gmc-sierra-1500s-and-chevrolet-silverado-1500s-101321.html Concern DATED and published on 10/13/2021 Why nothing has been done to warn the owners? I smell lots of lawsuits.

As I was backing into my parking spot I heard a bag then the engine light came on, after that it wasn’t shifting correctly, had it checked out and was told the transmission has to be replaced the mechanic said that this transmission is known to be defective it’s only a 2016 I feel there should be a recall could have been a disaster on the road.

VEHICLE SPEED CONTROL, ENGINE, FUEL/PROPULSION SYSTEM
THE SPEED OF THE TRUCK WILL NOT INCREASE. THE RPMS GOES REALLY HIGH AND THE TRUCK WILL NOT MOVE INTO THE NEXT GEAR. THE REAR END OF TRUCK VIBRATES. I TOOK THIS TO THE DEALER AND WAS TOLD IT IS THE TRANSMISSION FLUID IS FAULTY. THE CHECK ENGINE LIGHT DOES COME ON. I DID NOT HAVE THE NEW TRANSMISSION FLUID CHANGED BECAUSE DEALER SAID IS COST $300 FOR THE FLUID AND $100 FOR THE LABOR AND $168 FOR THE DIAGNOSTICS. SO I STILL HAVE THE SAME PROBLEM. ALSO TOLD YOU CAN NOT PURCHASE THIS TRANSMISSION FLUID NO WHERE BUT GMC.

ENGINE
The issues started when I began to notice that I was not having a constant flow of heat coming out of the vents inside of the vehicle. I brought the vehicle over to a local service center and the mechanic there discovered that my antifreeze reservoir was completely empty, but I did not have a leak. After filling the truck back up with coolant, a few days later, while driving, suddenly the truck began to run rough as if the vehicle went into "limp mode". I noticed that the check engine light was flashing and the traction control light was on. At stops, the truck would rough idle, shake, and there was a large amount of smoke coming from the tailpipe. I was able to get the truck back to the same service center that ran some diagnostic tests. He told me that there is a fault in the number 7 cylinder which has no compression in it. I had the truck towed to a local GMC dealership who confirmed that there was no compression in the number 7 cylinder and said that there was a lifter issue in the engine requiring an expensive fix. GMC had the truck from the Friday after Thanksgiving (the Year 2021) to January 4, 2022, to make the repairs. Repairs were delayed due to the dealership not being able to get the necessary parts in a timely manner.

STEERING, ENGINE
1. Truck is equipped with AFM (auto fuel management) I found out thru some research models since 2014 having collapsed lifters because of this feature. GMC has not made any attempt to recall this problem and let customers face the repair like me at the cost in my case of 7K. This truck has only 58879 miles on it. Not surprising models as new as 2021 had the same issue with no action taken to correct. 2.My truck lost the steering assistant feature putting me in a potential accident while i was driving. Steering the truck is difficult, especially at low speed which I decided not to drive it. I'm 87 years old and I'm facing numerous repairs for a vehicle with only 58K miles on it in order to safety drive my vehicle

ENGINE
Vehicle has a cp4 fuel pump. This pump has a high failure rate. Upon failure the vehicle shuts down and cannot be restarted. This can happen at any time and anywhere. Can happen while on a highway or freeway. This vehicle is used to haul heave loads. This failure can ending up to $10,000 or more to repair. This failure has not happened on this vehicle yet. Am very concerned about me safety and the safety of others because of the high failure rate.

ELECTRICAL SYSTEM, STEERING
When turning off the road to the right or left and then again left or ight in a parking lot, vehicle loses power steering and electronic functions, resulting in no ability to steer away for other objects or pedestrians. This is a major safety concern and i have stopped driving it since it started doing this. So basically any low speed turning from Right to Left or Left to Right i lose the ability to steer. When it happened at night at eh grocery store parking lot i noticed the interior lights flickered out and then back on also.

I started the truck and did not have power steering. If this would have happened while driving it could have been very dangerous. Why is this not a factory recall?
