at first my brakes began locking up on the vehicle, almost as if they were pumped full and not able to press down any longer, shortly after that the stabilitrack light came on and white smoke began to come out of the exhaust as well as a slight shake in the engine, i immediately turned the vehicle off and parked it, mind you i bought the vehicle 1 day ago and it is already broke down, the issue is with gmc and these sensors they are using they are faulty engine reduces speed and it is not safe to say the least.not only that but had the exact same problems with my Gmc Acadia which i finally got the light to stop going off after replacing transmission, brake pedal position censor, as well as gas pedal position censor, also had the throttle body replaced, Do you all make products that are worth anything, nothing was ever done about the Acadia, the Gmc sierra is a 2015 with 70,000 miles on it this car should not be acting like this please contact me at [XXX] thank you so much for your time, also there are 14 recalls on this year truck yet mine shows that there are 0 recalls to be fixed I am wondering about this as well.

I bought my 2015 gmc sierra 1500 certified and since then it has had vibrations when driving and hard shifts. The dealer has looked it over many times and said it's normal. Last month they said they sent gmc the readings and I haven't heard back. They have lied to me before about other vehicles and I'm tired of dealing with them not fixing it.
While operation my 2015 GMC 1500 DENALI Pickup at normal conditions my vehicle produced a engine light. I was three blocks from my office so I proceeded there immediately to have my vehicle scanned for codes. This is where I found out that cylinder #7 had an issue. This cylinder is part of the AFM system. I had the vehicle towed to Galles Chevrolet for diagnostic services and an estimate for repairs. Up receiving the results (which) I will attach. Bank 1 and possibly Bank 2 lifters and springs have failed. Thus possibly cause damage to the cam shaft. While I am aware that my vehicle is out of powertrain warranty (5 years / 100,000 mile), my vehicle only has 52,000 miles on it and very very well taken care of at all times. I am also aware of a class action law suite that pertained to the same exact issue on gm products from 2004-2014. Also service bulletins were produced by GM pertaining to this issue. Now I have been out of service of my vehicle for 3 1/2 weeks not to mention a potential $7000 repair, that should have never been in the picture! Poor quality control on products for potential profit gains have cost many many customers pain, anguish, and money.
The contact owns a 2015 GMC Sierra 1500. The contact stated that while driving at various speeds, the transmission failed to operate as designed causing the vehicle to sputter and not properly accelerate. Also, the digital speedometer display would not display properly due to a faulty radio. Additionally, the driver-??s side headlight failed to properly illuminate due to moisture build-up inside the headlight assembly. The vehicle was taken to the local dealer who was unable to duplicate the failure. There was no service performed on the vehicle. The manufacturer was not notified of the failure. The approximate failure mileage was 1,000.
Vehicle has roughly 52,000 miles on it. Noticed leak on passenger side, front. Opened hood, noticed fluid dripping down radiator. Took to garage, dealer identified radiator and ac system had leaks. Not covered under warranty.
Violent and erratic shifting during acceleration and deceleration... a simultaneous pop and jerk happens... also when accelerating and hitting passing gear the truck seems to stall out and then quickly engages to apply more power than expected... this can be dangerous for a driver attempting to merge onto highways/highways! the jerking occurs on a regular basis and at various speeds on various highways...
The vehicle is stuck in 4WD hi even though the indicator is set to 2wd. When turning at low speedfs the vehicle applies the rear brakes. The brakes do not apply when driving straight, only when turning at low speeds. It is dangerous when attempting to make turns from stops or parking.
The contact owns a 2015 GMC Sierra 1500. The contact stated that while driving approximately 35-50 mph, the contact noticed a minor shaking coming from the vehicle. The contact took the vehicle to love Buick GMC (736 Saturn pkwy, columbia, SC 29212; (803) 732-6500) who flushed and refilled the transmission fluid however, the failure recurred. The contact returned the vehicle to the same dealer who performed another transmission flush however, the failure persisted. The contact stated that the vehicle drove rough and that the check engine warning light illuminated. The contact used a dtc scanner and retrieved a code related to the transmission control module and temperature sensor. The vehicle was then taken stokes trainor Chevrolet Cadillac Buick GMC (2004 wilson rd, newberry, SC 29108; (803) 792-4763) and the contact was informed that the internal wiring harness needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the issue and informed the contact that the VIN was included in a special coverage program. The approximate failure mileage was 75,000.
While driving the transmission slipped while attempting to change gears. This caused the vehicle to be unresponsive and indicate a problem accelerating. This has been getting worse over the past several months and ended up leaving me in a very dangerous situation yesterday while driving.
My 2015 GMC Sierra has the 8 speed transmission which has been an issue since I have owned the vehicle. I bought the vehicle used in the fall of 2018 and the truck/tranny ran good for about 10 months. Then in late summer and early fall of 2019, the truck jerking hard shifts started to appear. In October of 2019 I brought my truck into my dealer to have them look at my tranny due to the really hard shifts from 1st to 2nd or 2nd to 3rd and vice versa 3rd to 2nd and 2nd to 1st. I had to pay a $80 diagnosis fee and they reprogrammed my tranny and the ECU to smooth out the shifts and not make the shifts so hard. In all the software reprogram did get rid of the hard shifts, but in return now my vehicle drove like it has a 6 speed transmission instead of an 8 speed. In June of 2020 I brought my truck back into my dealer to look at my tranny again! now my tranny felt like it was always "hunting" for a different gear. When driving on the interstate at 75 mph 1600 RPM, if there was a little bit of head wind or I started to drive up a hill, the tranny would downshift and RPM's jump up to 2200 RPM to make up for the difference in road grade, same as when driving in town up a hillat 35mph. A 8 speed transmission should not be doing that! at interstate speeds (75 mph) my passenger side seat will sit there and just wiggle and shake back and forth. I have changed out ball joints and struts with brand new ones thinking that was the problem and the seat still wiggles back and forth. When driving my vehicle it feels like I am driving with a 6 speed transmission than an 8 speed. I have read that this seems to be a common problem in these model year GM vehicles and I feel GM needs to finally address this issue once and for all and keep their GM customers satisfied. I didn't plan on buying a 3 year old used vehicle for it to have the issues it has had since I have owned it.
A few months ago I was accelerating from a stop light the truck suddenly and violently jumped forward it had felt as if I was struck from behind. However no one was there! I did take it to the dealer and they said they could not replicate the condition and no codes were stored. Yesterday this happend once again! I would have sworn some one hit me, the truck shook and jumped forward so hard it felt as if a buss hit me. Once again no one there! I am making this complaint because I see more people are having theses issues and GM calls them "normal" sorry but I have driven trucks for years and have never had one do this! this is a potential hazard because if at any time a car was in front of me I would have most likely hit the car! please fix this issue!
