2015 GMC Sierra 1500 transmission complaints
Page 3 of 4: complaints 41 to 70 of 99, newest first, as owners wrote them.
I was driving my GMC Sierra upon entering the highway, I was at a stop sign waited for clear traffic when it became safe to do so, I entered the highway and upon excelling up a small incline the vehicle transmission just completely stopped working so as I depressed the accelerator the engine would would wind the RPMs up but the vehicle wasn't going anywhere. I pulled the car over to the side of the road and placed the car in park. Put my emergency lights on and couldn't get the truck to the to go to the area to be free and clear of traffic to transmission engage. I put the car into reverse this is the second time this has happened and this is what my husband recommend I do. When I called him is to place the vehicle in reverse reverse a little bit and then place the car into park and then turn it off. Start the car up again and see if it would engage the gear, it took placing the vehicle in park. After adjusting the steering column and trying it again, the transmission engaged but would not reach the full acceleration. I was on a hill so I put the brakes on and the car brakes would not stop the vehicle. It would bounce and skid a bit as I was on an incline. The transmission was not engaging in reverse either. After resting then it didn't get any speed. There are RPMs just kept whining out. I wasn't able to at first get the car to go into gear after wiggling or adjusting the steering column then it seemed to go in gear but it would only go a few feet and then it the process would start over. this was dangerous as I was on a highway with an incline which means I had no break ability so I was rolling without control. I was able to get the car home and parked in my driveway but as this is the second event that has happened since we purchased the truck I'm making this report. Feel free to contact me if needed
At 101,000 miles I experienced my check engine light and Stabilitrak dash lights coming on and the engine spuddering. I replaced the fuel injectors, spark plugs, spark plug wires, coil packs. I’ve taken it to two mechanics one told me that number eight cylinder was low on compression and the other mechanic told me that he has seen very many of the same motor that I have, with the problems associated with the lifter recall. I don’t know what to do. I’ve heard that the fix is the same part so it’s just going happen again. This is horrible, from a consumer standpoint Especially since GM has known about this since 2007 with their AFM/DFM motors. I would love to hear back from you pertaining to what my options would be for repair and payment. Thank you for your time and have a good day.
The transmission has a HORRIBLE VIBRATION when driving. Either going slow or fast.
The 8-speed transmission in 2 and 3 gear exhibits a hard shift...no slippage. When slowing down to a stop you hear what sounds like two steel barbell weights slamming together. You feel like the transmission will break and leave you in the middle of an intersection. I have visited the dealer and they state this is normal. My vehicle only has 41000 miles on it. This has been an issue for me for the last 3 years.
The transmission is lurching forward when initially put into "D" then when driving it seems to be confused on which gear to go into especially between 40- 50. The other problem is the truck will make a shudder like driving over a washboard but only on smooth pavement, then shift into allow gear and the engine will rev up. is this something that the dealer will repair. I'm concerned to drive it.
The same exact vehicle my sister has and it has the same problems. But mine not on the recall , its the same model and the same year
Everything is horrible in the truck

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.
Coolant is leaking. Smoke comes from the front of the vehicle when it's cold out. Temperature is fluctuating.
Will not come out of 4 wheel drive from the auto select position ..stuck in 4hi will not release. Service 4 wheel light on
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...
Transmission went out in 5 years and would not work any more.
Aa soon as the warranty expired on my truck it start having problems with the transmission 🥴
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.
Tl* 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!
Torque converter. Me and along with 4 other people are having problems with it. Upon start up and driving it starts to get sluggish and then just comes almost to a complete stop only building RPM's accrodding to the gm dealership it's normal. With all the gmc trucks I've owned it has never done this. And is only starting to do it over the past couple of months. I've talked to a guy who just had 2 replaced in his truck and is continuing to have the problem. To avoid any vehicle damage for anyone else I'm considering if you can check and see if anyone else is having the issue. I take very good care of my truck I don't mud in it or drive it crazy(wreck less). Dealership is also pretty much refusing to look into the problem or diagnosing it considering that it's 'normal' for the truck do that. Which I strongly disagree.
Tl* the contact owns a 2015 gmc sierra 1500. The vehicle failed to shift and remained stuck in gear. Also, while driving various speeds, the vehicle accelerated without warning. The vehicle was taken four times to laroche chevrolet buick gmc cadillac (900 us-290, brenham, tx 77833, (979) 836-6666) where it was diagnosed that the transmission fluid and torque converter needed to be replaced, and reprogramming was needed. The vehicle was repaired, but the failures recurred. The vehicle was taken to mac haik chevrolet (11711 katy fwy, houston, tx 77079, (281) 497-6600) where it was diagnosed that the vehicle was working as designed. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but did not assist. The failure mileage was 7,000.*dt
When putting the truck into gear with the foot firmly on the brakes the truck will slam into gear causing the truck to jump forwards or backwards.
When I'm cruising highway speeds the truck get a violent vibration and makes the vehicle uncomfortable to drive.
