When traveling forward,or turning, at highway speeds between 20 MPH and 40 MPH, this vehicle shudders ( 6 speed transmission)and acceleration pauses until a lot of extra effort is placed on the gas pedal.the transmission then downshifts with a sudden lurch. This leads to a safety hazard when instant acceleration is needed.this happens everyday at any time of the day and whether hot or cold.
2016 Chevrolet Colorado transmission complaints
Page 3 of 4: complaints 41 to 70 of 97, newest first, as owners wrote them.
Vehicle shudders does not downshift smoothly jerks when backing up at times, vehicle jumps when trying to shift to a lower gear. Brought to dealership, couldn't get the problem to occur, so nothing they can do and don't care to, vehicle has 36,000 miles
Driving my 2016 chevy colorado lt 4x4 down the highway and also on 2 lane roads in great weather conditions the service power steering and stabiltrak lights came on. Electric steering was disabled and I had extreme difficulty with turning left or right. This is the same recall as gm 15595. Turning the vehicle off and on resolves the issue temporarily. Now it is happening more and more and I do not feel safe with my family in the vehicle.
When driving in stop and go traffic, and through city and residential areas, the transmission seems to struggle finding the correct gear. The transmission hesitates and does not shift as smoothly as it should, and sometimes shifts hard upon reacceleration, or sudden braking. The transmission also struggles to find the correct gear while highway driving (70-75 MPH) with constant grade changes, and hills. (interstate 5 from los angeles to bakersfield ca. ) when starting the vehicle and placing it in reverse to back up, the transmission shutters slightly before engaging properly. This usually happens on a slight grade, as my street and driveway moderately sloped. I took the truck at the dealer for and unrelated issue, and ask them to check it. They said it was "normal". I have read about similar complaints on several forums, and its seems to be a very common complaint. This transmission seems to be junk! The time frame for this complaint is from 2/1/2019 (22,000 miles) to present. Others have complained with as little as 4,000 miles.
The transmission is extremely slow to downshift. As you continue to push the gas pedal, it will finally downshift, sometimes two gears, and suddenly accelerate. When on cruise control, you loose about four MPH before it finally downshifts, again sometimes downshifting two gears. In traffic, the car behind you doesn't anticipate the loss of speed and then you suddenly accelerate. It happens at all speeds, but is particularly unsafe at low speeds with the sudden acceleration. This is probably a software problem as the transmission shifts much more normally if you put it in 'tow/haul' mode. The dealer says this is 'normal' and gm calls it ' torque management '. It is especially unsafe in slick conditions or rainy roads. Btw, I have a 2017 impala with the same six speed and v-6, and it does not exhibit this reluctance to downshift. Thank you.
When I put the vehicle in park quite often when I turn the keys to the off position the keys don't go all the way off until I shift into gear a few times and back into park. I took in to the dealer and they said they cycled it many times and it was fine I brought it home and guess what the same thing. It is still happening
When pulling into traffic circle from low speed, no throttle response. Engine died or had no input to propel vehicle. Change of gear selector had no affect. Not until pushed to side of road, completely shut off and remove key did engine restart or have any response to throttle input.
The transmission (6spd automatic w/v6 engine) of this vehicle is known to have issues that will surprise you if you aren't already aware of them. The issue affecting safety the most, is the occasional engine acceleration while applying the brakes as the transmission downshifts to a lower gear. It causes the car to actually accelerate momentarily as you apply the brake even harder to arrest the increased speed. I was driving up a slight incline at about 35-40 MPH when all of a sudden the car in front of me came to a complete stop because the car in front of her had stopped completely. I had driven this road for more than 30 years and had never seen anyone come to a complete stop as the first car did in this area. Five(5) of us were all surprised. I was the third car. As I firmly applied my brakes, the car initially slowed down but then it felt as if it was trying to accelerate and unfortunately I was unable to stop in time, although I only lightly tapped the car in front of me, followed by 3 more cars in back of me. At first I was surprised that I wasn't able to stop in time and then it occurred to me that the strange feeling I felt as the vehicle slowed was as if the engine had accelerated as it downshifted causing the braking action to not be as good as it should have been. Since I knew the car occasionally did this I thought I should report this as possibly contributing to my problem and put it on record in case you had other reports like this.
While stationary I tried to switch from 4wd auto, to 2wd. The light flashed and failed to change, then a service 4wd system popped up. The vehicle is stuck in 4wd auto and now loses all power while trying to turn.
In 4 wheel drive turning left or right vehicle slides.skids,bounces and tires chirp from traction loss giving the sensation the drive train is falling out. Gm refuses to contact me. This occurs on city streets, highways while in motion. Not on a specific date but constantly. Rain or shine.
2016 chevy colorado with less then 10,000 miles. At low rpms on any incline truck will buck, sputter, and hesitate rather than automatically shift into lower gear. In city traffic, after slowing to make a turn then accelerating, truck will buck and sputter and drive train will make a hammer sound after engaging . I took it to dealer who said he could not duplicate problem, although this is a known problem.
Tl* the contact owns a 2016 chevrolet colorado. The contact stated that a loud abnormal noise was heard when shifting into park or reverse, and the vehicle hesitated before shifting into gear. While driving 45 MPH, the vehicle lost power without warning. Also, when the vehicle was engaged in park, the key was unable to be removed from the ignition. The vehicle was taken to bellamy strickland chevrolet buick gmc (145 industrial blvd, mcdonough, ga 30253, 770‑954‑3000), but the cause of the failures could not be determined. The manufacturer was not notified of the failures. The failure mileage was approximately 35,000.
I purchased a brand new 2016 chevrolet colorado duromax diesel in september of 2016. At 9,638 miles the check engine light came on for the nox sensor. The dealership replaced them but it did not fix anything. As it turns out the issue was a recall which reprogrammed the ecu. They decided to make the tolerances looser on the sensors. At 10,647 miles there was a loud wining coming from the rear of the vehicle. The race to the pinion bearing in the rear differential was pitted and causing the bearing to fail. The rear differential needed to be rebuilt. At 22715 miles the truck would go into reduced power mode which is 25 miles per hour in the middle of the freeway causing other motorists to swerve to avoid a collision. When the truck was turned off and turned back on the error would clear and the vehicle was drivable again. The dealership could not replicate the issue so it took many visits before they replaced the accelerator pedal position sensor. After this did not fix the issue and almost caused another accident the vehicle was taken in and the complete wiring harness was replace. The technician stated that the connectors were improperly crimped at the factory. The truck is now at the dealership again at 26,000 miles to replace the diesel exhaust fluid pump. This fault also causes the vehicle to go into reduced power mode which almost caused an accident again. This vehicle is not reliable, dangerous, and I do not feel safe driving it, especially when my family is with me. I contacted chevrolet customer assistance team concentrix on behalf of chevrolet to seek a solution on a brand new vehicle that had major problems. The representative did not care and told me to pursue a resolution on my own.
Numerous times while driving, and going downhill the truck shifts to a much lower gear causing the RPM's to go up to 5500 and does not shift out. Twice I had the cruise control on and was on the highway (speed of 75) going down a hill and it shifted to a much lower gear. It has done this on other roads going down hill as well. In addition, numerous times when merging with traffic on a highway, I will try to tap the accelerator to safely merge with traffic and the truck has gotten "stuck" in a lower gear and would not shift out and I thought I was going to rear end a car so I had to ride my break to make sure it would not continue to accelerate into the back of a car. In addition to that, often when trying to accelerate out of a corner or after an off ramp, the truck will not accelerate at the same rate as the other vehicles around me. It will slowly accelerate as the vehicles around me pull away. In addition to that, when I am on the highway and I need to accelerate quickly to safely pass traffic, I have to push the pedal to the floor to ensure that the truck will actually accelerate. The dealer just tells me that the software is up to date and they could find no record of similar issues.
Rear differential making loud poping noices when engaged. Sounds like metallic metal to metal catching and grinding. Specially when switching from backing up to driving forwards again. Is could result in the differential locking up.
Key could not be fully shut off,removed.dealer determines a solonoid on shift assembly failed.solonoid could not be purchased so a new shift assembly was ordered.I was barely outside my warranty.chev refused to cover.this is a hazard because without shutting off,locking column and trans it become a fire risk,theft risk in that key cant be removed.04
Transmission has a "stutter" to it. Upshifts have a 'stutter" or lag to them at low RPM. Very dangerous driving around town when you have stop and go traffic. Downshifts automatically going down a steep grade ,the downshift is so bad it wants to throw you through the windshield.have had truck to dealership at least 3 x. Truck is dangerous to drive in traffic as this transmission is not working properly. Have contacted gm in dec. Of 2017 but got no reply (imagine that). Truck has about 18,500 miles on it bought in dec. Of 2016. Highway driving is fine, driving around town is terrible as I said transmission "bucks" or "stutters". For the time being truck will sit and will not be driven except to the dealer.
During ownership of my 2016 chevrolet colorado v6 gasoline engine vehicle it has had numerous sputtering situations when accelerating. There is no rhyme or reason as to why the truck sputters to almost stalling. Dealership claims that the fuel injectors are probably dirty / fouled. Had injector maintenance performed and truck has no better engine performance and sputtering continues. This is dangerous on highway when accelerating in traffic. This has been occurring since original purchase date in october 2015.
Tl* the contact owns a 2016 chevrolet colorado. While backing out of a parking lot and attempting to make a left turn, the vehicle "jumped and made an unusual noise". There were no warning indicators illuminated. The contact drove to his residence and parked the vehicle. The dealer was not contacted. The manufacturer was not made aware of the failure. The failure mileage was 33,026. The VIN was not provided.
Transmission erratic shifting at low speeds . Transmission acts like it is lost and does not know what gear to go too . Hundreds of internet complaints with no fix .
Transmission hesitation: vehicle doesn't accelerate when its supposed to. When going from a normal rate of speed to slowing down to make a turn, doesn't downshift properly, therefore when you make the turn and accelerate again it hesitates (nearly stalling) jerks and skips. Have had many close calls because of this. Nearly being rear ended on several of those occasions. Have tried contacting gm about the problem and got nowhere. Have been put on a waiting list at the dealership with no indication of when this will be fixed. It has even got to the point where my fuel economy has seriously diminished.
Transmission fails to downshift properly and shutters when coming back under acceleration after slowing (to yield for example) and sometimes shutters when coming to a stop. If I tap the accelerator to force it to downshift, it violently shifts to a too-low gear and the engine revs too high.
Noticed immediately after purchase with 18 miles. Noticed at slower speeds under 45 MPH the truck would up-shift to a higher gear when letting off the accelerator. Upon depressing the accelerator again the truck would hesitate, jerk,ping, or just plain not accelerate until excessive pressure was placed on the accelerator. At this point it would down-shift hard a couple of gears and cause unsafe acceleration in high traffic scenarios.
Tl* the contact owns a 2016 chevrolet colorado. The failure recurred numerous times. The vehicle was taken to a dealer where the cause of the failure was not determined. The manufacturer was notified of the failure. The failure mileage was approximately 102,000. Updated 06/23/17*lj
At approx. 3500 miles started experiencing shifting issues. When slowing down transmission wanted to stay in 5th or 6th gear. Attempts to accelerate caused the truck to bog down until it shifted to a lower gear to accelerate again. When in cruise control problem was really bad. Would loose as much as 5-8 MPH before a lower gear was found to maintain speed in hilly conditions. I took vehicle in for its first service at approx. 6000 miles and had dealer check transmission. They remapped shift points to spec software. This was a temporary fix. Issue is slowly returning. I have watched on control panel at transmission oil temp ( truck has trailer towing package etc. This is a cluster feature available.) seems to shift properly until oil reaches 100 degrees plus then issue arrives. Dealer relayed there had only been a tech service bulletin has been to reset map/shift points. Recently pulled my boat with this truck and transmission shifted fine. Really would like this issue fixed because other then this problem really like the truck.
The truck when slowing down to around 20mph and accelerating seems to lag or for lack of a better description seems to be "unable" to find the correct gear. Sometimes it acts as if the engine has a "miss". I took it to the dealer and was told this is "normal operation". When you google this complaint there is page after page of owners having the same problems with 2015 and 2016. It seems to me this is a programming issue with the transmission. It seems to have trouble finding the correct gear and will sometimes jerk or downshift too low. It happens at any time the vehicle slows down to around 20 and accelerates. It also happens at times when at a full stop and taking off in a normal manner.
When trying to accelerate from a low speed, maybe 20 MPH or less, the transmission often does not deliver any power to the drive wheels (the motor revs up but the vehicle does not accelerate). Also, when climbing a hill at normal road speeds the transmission often does not down shift, to the point where the motor almost stalls, and the few times that it does down shift there is an explosive increase in engine rpms resulting in an almost uncontrollable burst of vehicle speed. Chevrolet says this is the way it's designed to work. If it is, it's the first vehicle I've seen, or even heard about, that does these dangerous things.
Vehicle stalls. When navigating a corner transmission looses its gear and acts like it doesn't know what to do and bangs and stalls. Also trans acts confused stop and go situations(city) and bangs when it remembers. Also does this when coasting on highway and accelerating again. It may jump down several gears and take off. Vehicle also has stalled several times at red lights and has a rough idle most of the time like it wants to stall. Been in shop numerous times for same thing and advised chevy but they cant figure it out and it is still doing it. Also looked online for possible answers and there are a lot of these same problems reported with no answers.
Chevy 2016 colorado z71 v6 with a 6 speed automatic: the transmission does not shift under light acceleration or when under load going up a hill. The truck hesitates seems to miss and doesn't know what to do to get it so accelerate! It also has this issue when lifting my foot on the gas when rolling through a corner and then hitting the accelerator. Then I have to push the accelerator hard to make the transmission up shift 2 gears to make the truck accelerate! This is frustrating and dangerous as it could cause being hit from behind when the truck does not accelerate as it should. I took my truck back to the dealership three times and they said 'there are no codes, there seems to be nothing wrong the computer doesn't know whether to stay in that gear or up shift 1 gear or 2. All you have to do is to push down harder on the accelerator and learn to drive with a smart transmission.' my reply was 'I am not part of the vehicle sensor system and I should not have to learn how to drive to a poor shifting situation especially when I am paying this much for a new vehicle.' gm should be forced to fix this very common problem before something serious happens as a result of this!
Low to moderate speed gear shift hesitation, transmission not smoothly shifting,. Feels like a bad miss. Electronics and transmission/engine not in synch or synching. Hesitation, lack of responsiveness can be sever at times. Reboot of ECM helped, but issue has returned worse than ever. This has been a problem since day one of ownership. Hill decent control activates at al speeds including high end hiway speeds. 40, 50, 60, 70+ MPH engagement - tap the brake and it actives. Engine RPM's go through the roof. Disabling the control wit the button does not deactivate. Dealership has not and does not offer any solution. Sever loss of control of vehicle could occur in inclement weather or other conditions. Also, fast slow down with no warning to other drivers in the vicinity. Engine RPM's as high as 5k in my truck in mountainous pennsylvania december 2016.
