Truck transmission was good until about 2,000 miles. truck has delays when putting in gear after it sits overnight. truck has harsh low speed downshifts. problems are real bad when vehicle is cold. when you come to a complete stop and let off the brake the truck will sometimes lunge forward. took truck back to the dealer where i bought it and they said nothing was wrong so i made an appointment for a week later with another dealership. they did a "timing" test and felt the delay and did 16na364 update. it seemed to help for a couple of days and problem returned. both dealerships are aware of the problem but gm is not providing a fix. i now warm the truck up a few minutes before driving to help with delayed gear engagement. harsh downshifts continue with the lunging and slow response at times when applying gas petal. you have to be very careful when driving this truck because of the transmission problems. there are many complaints for this not to be a major problem. this vehicle sticker price was $64,000 dollars. i wish i had my old truck back because it was reliable and not potentially dangerous to drive. general motors need fix this problem or at least give an free extended warranty. the dealers will fix the transmission if gm will tell them how.
6.2l engine with 8 speed transmission. erratic transmission shifting including downshifts so hard on the highway the rear wheels will lock up momentarily and throw occupants forward. taking off from stoplight will intermittently experience delayed engagement and engine will rev to almost 1500rpms before the transmission engages. tires bark, scares the heck out of driver who them immediatley slams on brakes in traffic thinking something broke. dealership cites normal operation with no fixes available from gm. lots of similar stories online and the first class action suit against gm for these 8 speed transmissions has been filed.
Transmission downshifts rough.
A rough clunk noise occurs when trying to stop, and car actually revs to accelerate speed when applying breaking and trying to stop. (in . motion) this is a dangerous issue. transmission does not appear to smoothly enter into subsequent gears. a jerk occurs in between shifting of gears. (moving) i have been completely stopped on a flat street, and relax my foot off the break, and the car wants to leap jump forward. this is not safe. (stopped) there are several reports of this issue found in online forums from other owners with the same 2017 chevy silverado. just purchased vehicle in november.
The pickup shakes at speeds typically between 30-45 and 55-75. it shakes hard enough and long enough at times where at higher speeds becomes dangerous because it compromises the steering where the truck can come off its line and become unstable. it will also shake randomly and for unknown periods of time. when it starts i have no control over it and no control over when it starts or stops. i have brought it into the dealer a couple times now. the first time they said i needed to rebalance the wheels and put on new tires so i did both. the second time they said it was a problem with the engine/drivetrain when it deactivates 4 cylinders. they told me there is nothing they can do for this problem. i have researched this and it seems that it is a problem with this specific engine and gm is claiming there is not a safety issue. this is completely false as the truck becomes unstable and steering is compromised. at highway speeds this is a huge issue especially if this continues into winter months where road conditions are not the best.
6.2l engine had faulty injectors and had to be replaced. gm said my truck had a warranty block so i had to contact the bbb and go to mediation to get injectors replaced. now i'm noticing a shudder (vibration) while driving with a fluttering of the rpm's. all my research has led me to believe it is a faulty torque converter. my wife has a 2017 camaro that is having the same issue. dealership stated that they are replacing the faulty torque converters in vehicles with 8 speed transmission, but will not replace mine because gm has put a block on my warranty. gm cannot provide any evidence giving them reason to block my warranty on my vehicle.
8 speed transmission harsh jerks between 1st and 2 gears and 2nd and 1st gears typically occurring on slight downhill grade harsh jerk and knock/hammer noise common to occur after vehicle has been sitting and in stop and go traffic such as school drop off with children around and rush hour traffic
The truck has a hard time accelerating and randomly upshifts and downshifts. when coming to a stop it has a hard time downshifting which makes it hard to stop. when on the interstate in rush hour traffic it is very dangerous to drive because i have no idea if the truck will accelerate or not and since it has a hard time stopping i am afraid i am going to rear end someone. another issue the truck has is with the four wheel drive. it works good but it makes a really loud grinding noise when engaged. i am taking it to the dealer today as i have before. i am hoping they take a serious look at it and fix the issues.
Vehicle was parked in a shopping center parking lot after being driven for approximately 15 minutes. when returning to the vehicle 10 minutes after parking it, the vehicle starter was attempting to start the vehicle despite no remote start or onstar app being activated to start the vehicle. the vehicle continued to attempt to crank and start, even after i unlocked the vehicle with my key fob, inserted the key into the ignition, and attempting to start the vehicle and turn off the key. the vehicle continued to attempt to crank and start and i smelled a strong electrical burning smell. i then saw blue/greyish smoke coming from the passenger side where the hood meets the windshield. i then gathered my belongings from the truck and watched from a safe distance. after the smoke, the truck no longer attempted to crank or start itself and the smoke was gone within 5 minutes, although there were small instances of smoke over the next 15 minutes. the truck was put on a flatbed tow truck for further diagnosis at the local chevrolet dealership. initial diagnosis indicated that the "starter had consumed itself" and was the cause of the smoke i saw, but no further information was available. it was quite scary to have a truck attempt to start itself with a small electrical short/fire as a result without a key being needed.
Transmission abruptly shifting. feel like the truck is being hit by another vehicle. i don't know when it's gonna do it but when it does, its scary. the other day while trying to back up into my drive way, the would not move when i pushed on the pedal. then on it's own, the truck burned rubber backwards when i took my foot off of the gas pedal. i almost drove into my garage! this truck is not safe and needs to be removed from service! this is an ongoing problem that you never know when it's going to happen during you drive.
The transmission shifts hard in low gears (upshifting and downshifting), lunging forward and a hard knock in the transmission. chevrolet cannot fix it!
Purchased my 17 chevrolet silverado 1500 on 11/28/17 and returned it to the dealership on 12/1/17. this was due to a severe shuddering & shifting in the transmission & severe shake in the front end at 70-90mph. they balanced & rotated the tires, saying the issue was fixed, i picked the vehicle back up on 12/4/17 but the issue was not fixed & an electrical issue had also occurred. i took the vehicle back on 12/7/18 with the same complaints regarding the transmission & shaking in the front end, as well as the electrical issue. the problem electrically was while sitting at a stoplight the bright lights flashed & the radio/navigation screen went blank. the dealership called me on 12/8/17, told me they had been unable to duplicate the issues, finding nothing wrong. i left it over the weekend, went in monday morning & spoke to the service manager directly. he told me he had purchased the same vehicle with the same transmission issues. said there was a possible fix by exchanging the transmission fluid & they would use a new machine pico to check it out. they had to replace the torque converter due to malfunctioning & perform a programming module update on radio, i picked it up on 12/22/17, issue with the transmission was still not resolved. i took it to a different dealership for transmission shudder, shift & shake issue most noticeable at 70-90mph, & radio issue. they were advised to perform a module update on the transmission & given 2 options on the radio, they chose to replace the screen. i took it back to that same dealership, module update made transmission/front end issue worse, especially coming out of a curve. they've replaced my 2 back tires said they were bad & should fix the shaking issue in the front end. unable to duplicate transmission issues thus they cannot repair it. owners with the same issues are being told gm knows but can't fix transmission issue.
Unsafe characteristic!!!! inadvertent hard shift between 1st and 2nd gear or when driving less than 10 mph. the severity of the shift has nearly caused multiple accidents due to unpredictability. when this happens it is a very startling event that can make you increase throtle press and accelerate the vehicle, oversteer in low speedturns, abruptly apply the brakes to keep from running into objects including people and dizzyness from your head striking the headrest. each morning when i leave for work i have to make a u-turn. i never know when or how hard the transmission will kick. i've almost ran into a sign/pole if i hadn't quickly steered away from it. when looking for a parking place within a parking lot, the truck will sometime hard shift in and out of gear. i don't feel safe or confident in this truck. i'm scared to let my wife drive it in this condition. iwas told by local chevy service dept that is in a normal charataristic of the transmission. that gm is aware but will not correct the issue. this is my 5th chevy vehicle and my 3rd truck. none of the others had this issue. please advise...
8 speed transmission shift very rough from 1-2 and 2-1 gears, frequently hesitates, makes clunking sound. have taken it to gm dealer and am informed that yes, that's the way the 8 speeds are. this is a $50k + truck. this transmission issue causes and can cause hesitation when needing to accelerate, thus creating a safety hazard.
Transmission shifts hard and vehicle surges at low speed with accompaning "clunk". problem occurs in both upshift and down shift. dealer informs me that is a "learning" curve for vehicle to understand my driving habits. however i see on several automotive forums that this has been an issue for some time and has yet to be resolved.
Experiencing hesitation/'chuggle'/convertor slip in 2nd-6th gear in v8 mode when rolling into the throttle and putting the engine under load on a highway. especially noticeable when in 4th 5th or 6th gear,1500-1850 rpm, loading the engine to accelerate 55-60mph, 60-70mph. or when accelerating on an incline at same speeds without downshifting. or when slowly applying throttle to maintain speed (65+) against a head wind or when trying to pass a car. all while maintaining current gear and no downshifting.
I bought my pickup brand new from a certified chevrolet dealer and have had an issue since i test drove it. when shifting under low throttle from 1st to 2nd gear and back down from 2nd to 1st, there is a terrible clunk. sometimes its barely noticeable, and other times if feels like i've been rear ended. there is an extremely noticeable hesitation when starting off from a complete stop, which could potentially put myself and other drivers in danger. i've brought my vehicle back to the dealer multiple times and have been told that there is no fix.
When coming to a stop hearing a clunk in the drive train had same issue with 2016 silverado chevrolet replaced control module and calibrated gears on 2016 but when i told them about the same issue with the 2017 i was told this is normal so why would they waste time and money trying to repair an issue in their words is not an issue is beyond me, this needs to be recall item befroe mechanical failures resut in injuries or loss of lives.
Front bumper sensors not working as designed, transmission hard shifting in low gears (city streets and highway), clock time changing on it's on by 15 min (stationary), speed display not functioning (on highway and city streets), windows going up and down on their own (stationary, in motion), gps will not complete trip directions (highway), blue tooth function losses calls or has static interference (city streets, stationary and highway)
Shortly after purchasing my truck, i began experiencing hard shifts, gear searching, clunking and hanging between gears. occasionally the shift would be so hard it would feel as though the truck was struck from behind by another vehicle or object. multiple trips to the dealer has resulted in numerous attempted fixes with no relief of the problem. currently the truck is back at the dealership having the entire transmission replaced. this is causing a depreciation of the value of the truck as well as an unsafe condition while driving.
When driving veh shifts hard causing a jump or unexpected acceleration. brouht it to huntington chevrolet they stated it was normal. i do not feel safe in this vehicle.
When going slow and the truck shifts from 1st gear to 2nd gear you can hear and feel a strong knock and it pulls the truck this also happens when going down in gears from 2nd to 1st at slow pace and it doesn't happen all the time but more often then not if your driving slow like in a parking lot it happens 6/10 times took it to the dealer stated no recall but they are aware of the issue but were instructed not to do anything to the truck verified google and a lot of other people are having the same issue
Tl* the contact owns a 2017 chevrolet silverado 1500. while driving 45 mph, the transmission failed to shift properly and made a clunking sound. the failure recurred multiple times. the vehicle was taken to a dealer where it was diagnosed that the transmission failed and needed to be reprogrammed. the vehicle was repaired, but the failure recurred. the manufacturer was made aware of the issue. the approximate failure mileage was 30.
Tl* the contact owns a 2017 chevrolet silverado 1500. while driving 25 mph, the vehicle shifted hard from first to second gear. the failure occurred everyday since the vehicle was purchased in april of 2017. the vehicle was taken to o'reilly chevrolet (6160 e broadway blvd, tucson, az 85711) where it was diagnosed that the transmission control module failed. the dealer reprogrammed the transmission, which failed to remedy the failure. the vehicle was brought back to the dealer and the valve body for the transmission was replaced and the transmission fluid was changed. the failure recurred. the manufacturer was notified of the failures. the failure mileage was 16,000. *tt
Transmission on my new 2016 z71 lt 4x4 jumps into low gear when slowing down. i took it to the dealership multiple times, but keep getting told it shifts fine. i took it again and had a manager drive the truck with me inside and agreed the transmission was not gettin into gear in a normal way. toon it back to get it fixed and was told transmission is fine. i need this fixed or i will be returning he truck as a lemon title.
Truck exhibits a rough idle after truck is driven and warm. idle causes teh truck to shake and feels like it will die at stops. rpm drops below 300 rpm then goes back to 490 rpm. in addition the truck will start to shake and vibrate at highway speeds of 75-80 mph. gmc service performed tsb changing our engine mounts but that has not fixed the issue. this is a known issue on silverados and no fix in site. concerned with seat vibration this is a safety issue due to potential drive train part failure.
