general problems of the 2016 Chevrolet Colorado - part 2

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.

Poor shifting, engine bogging down going up hills, shudder. I have had vehicle in to at least 3 different chevy dealerships complaining of shudder, slipping and they claim they can't reproduce. It's getting much worse now. Started around 60k miles.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Vehicle has erratic downshifting and upshifting of the automatic transmission causes abrupt changes in acceleration and deceleration that sets up sequences that force the driver to continually press down on, or let up, on the break and or accelerator to attempt to blend in with stop-and-go traffic. Only getting 15-16. 5 mpg city driving.

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.

This vehicle's erratic downshifting and upshifting of the automatic transmission causes abrupt changes in acceleration and deceleration that sets up sequences that force the driver to continually press down on, or let up, on the break and or accelerator to attempt to blend in with stop-and-go traffic. In very heavy traffic, present when entering or leaving large cities, the onset and continuance of this vehicle's performance worsens resulting in driver fatigue and extreme stress, brought on by the ever present necessity to be extra watchful and to maneuver to avoid hitting the vehicle in front, or being rear-ended. When driving through mountainous terrain at today's interstate speeds, there is recurring "bumping" that sets up when ascending long grades. It creates the feeling that either the transmission is attempting to downshift but then changes its mind, or the engine's rpm are about to increase but don't. This adds to fear of imminent failure and being left stranded. This behavior was present from the very first time the vehicle was driven. It's getting worse. This driver believes the unsafe operating performance of this vehicle as described above, is exacerbated by the combination of the small, 4 cylinder engine coupled to the 6 speed transmission, that requires the engine to rapidly downshift or upshift to provide the needed performance required in today's driving environments. Further, it is evident the software controlling the transmission's operating behavior was neither fully developed nor tested throughout its anticipated full operating range and as such creates a vehicle that is dangerous to operate on public roads attempts to have these issues addressed with the dealer resulted in being told. . . " nothing can be done. . . The problems you are encountering are being are being experienced by many customers. Chevrolet is not providing any solutions".

Since purchase of vehicle, it had a bucking at speed of 25-40 mph, this was very noticeable in city driving, this issue was couple with uncontrolled surges in the engine. The vehicle was purchase oct 28 or 30, 2016. I turned in the vehicle for service on Dec 19, 2016, dealer service rep confirm there was an issue and keep the truck for repairs. Vehicle was in the service department for over 40 consecutive days to fix issue, dealership techs, as well as gm field reps have looked at the vehicle and have tried to fix it to no avail. On Feb 8, the gm rep said there is nothing wrong with the vehicle and the issue was a software problem with this specific type vehicle and that the software this vehicle has is a new software. When I asked if this issue is being worked by the software engineers for solution the rep said he has no idea and that I should take the vehicle back. This issue is a safety problem especially when suddenly surges without control, particularly while driving in a city center a driver can cause an accident or potentially hit a person while loosing control. Gm costumer assistant was contacted, but there was not help and gm refuses to let me know when the fixes for this issue will be out. Therefore I have refuse to take possession of vehicle until if fixed correctly!! this issue will affect all 2016 and up Colorado with duramax engine and new software version installed on them.

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.

In motion, when driving speed limit and then you let off accerlerator to slow down and then you press gas again it hesitates and does not want to accelerate. I took to dealership and they said they fixed by programming something in computer and it ran fine for 3 days and started doing same thing again. And also, when you accelerate and it will not respond you give it a lot of gas and it makes rpms go to like 5000, but the rpm do not match the speed, its very strange. I see other complaints aboy the same thing on forums.

Transmission down shift slow to respond. Feels like it is out of gear, or like a engine hesitation, steeping down on accelerator hard makes it shift but the shift is hard. Concerned about this happening on ice causing a possible spin out.

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.

Transmission does not downshift properly under any type of acceleration (slow or sudden) especially between 20 mph and 40 mph in normal street traffic and on the highway. It also hunt for gears especially between gears 4 through 6. It hesitates for approximately 2 to 3 seconds, finds a gear, hesitates again, and then drops to an even lower gear and over accelerates. What I have observed is that the vehicle is too eager to upshift and sometimes goes into 5th or 6th gear and drops the engine below 1000 rpm. It stays in that gear when slowing down and when accelerated it stays in the high gear on bogs down and on two occasions stalled. This is dangerous especially in highway traffic and is especially dangerous when accelerating to pass or accelerating on an highway onramp to merge with traffic. I have take the truck to dealer at around 2000 miles. Was told that they couldn't find any problems and they "reset" the transmission. It ran fine for one day and began the problems again. I have operated the truck now to 6000 miles to see if the transmission can "learn" its way out of this and it has not. I am going to dealer again and if they tell me again that there is no problem, I am going to force the service manager to drive with me for a day to experience the problem.

"the transmission does not downshift from a high gear (5 or 6) to a lower gear when slowing down from 45 mph to 20 mph (or lower). When the accelerator is depressed to accelerate the engine bucks, vibrates, and does not accelerate. The engine rpm drops to 1,000 rpm or lower. If the accelerator is quickly floored the transmission downshifts several gears lower and jerks forward. This condition happens primarily on secondary roads while driving along the road and when pulling from one road into traffic on another road. The situation when pulling into traffic is dangerous because the truck does not accelerate as it should. This truck was purchased new and has 1200 miles on it. This condition has been present since the truck was purchased and the severity varies with truck speed and road inclination. I reported the situation to the dealer and they attempted a fix (had the truck for three days) that supposedly involved a "new download" from Chevrolet, but it didn't change a thing. Dealer knows it didn't fix anything and says Chevrolet may have a "recall update", but reading all the other similar complaints, I'm suspicious. In the 1 month I have had the truck, I have almost been hit twice by approaching traffic because of hesitant acceleration. This is a dangerous problem and Chevrolet need to fix it immediately. I.

On numerous occasions while entering/exiting vehicle my knee lightly brushes the 4 wheel drive engage switch located on the dashboard. This activates the 4 wheel drive on the vehicle. This is happening without my knowledge. Since there is no obvious indicator on the dash the the vehicle is in 4 wheel drive, if I do not notice the brief "engaging 4 wheel drive message" there is no way of knowing that it is in 4 wheel drive until the vehicle starts "hopping" on dry pavement while turning. Should this happen at highway speed on a curve there is the strong risk on a rollover. I have found myself having to regularly check the knob in order to determine if the 4 wheel drive is inadvertently engaged by this light brushing of the knob.

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!.

While driving the 2016 Colorado, the transmission/engine seems to have trouble shifting and accelerating and the shift patterns are erratic it seems, maybe its the fuel efficient crap that shuts down cylinders, maybe its the trans? . Experienced it on highways and lower speeds, stop and go traffic, truck's transmission clunks, shifts hard at random and stutters allot . It's aggrivating. When trying to pass, seems to be zero acceleration felt when flooring it then suddenly kicks in (roughly). . Like OH hey-I need to go. . I could get in a wreck-ended because of this and I better not try to pass anyone. . I feel my safety could be at risk with as much hesitation then suddenly lurches as it has. I see quite a few complaints already concerning this and/or describing just about the same ordeal. Daily - but random - city and highway, turning, straight etc. Basically any situation but idle.

Vehicle hesitates and stumbles on acceleration during motion when acceleration is resumed while moving. It seems that the transmission is not shifting down. You have to get into the acceleration, which is a safety condition in traffic. At times it stumbles bad enough to slow speed dramatically, which is also a safety condition on interstate. Took the vehicle to dealership and they are dedicated to saying that there is no codes up and I am nearly at the point to seek help from lawyer on the situation.

Vehicle stalls sometimes when I stop. Se light is now on. Service brake assist comes on now. Truck surges and shutters and is annoyingly hunting for gears and can't find them. Sluggish throttle like I'm trying to pull a bull dozer out of the mud. This mostly happens between 15 and 40 mph back roads and highway stop-n-go. Not settling for the "OH that's normal" bsht. Should have bought a Ford f150. Time for a trade in. 10k miles and I am completely disgusted with chevy now. All I can say is good luck if you have a 2016 Colorado.

The contact owns a 2016 Chevrolet Colorado. While attempting to shift gears, the vehicle began to hesitate. 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.

When merging onto I-70 freeway from on-ramp, I applied throttle to move into the traffic flow. Engine "stumbled" as if in a dead spot. Truck did not accelerate and appeared to be lugging badly. Transmission was in too high a gear and seemed to be searching for correct gear. During this time oncoming traffic was forced to brake and there was a near miss of having a rear-end collision. All I could do was watch in the rear view mirror as traffic converged on me. This "dead throttle / wrong gear" issue has happened repeatedly on surface streets but luckily on surface streets I was not in such a critical situation. This is a problem that has been reported repeatedly and at many places on the internet. When will NHTSA force gm to address this issue? hopefully you will act before this results in serious injury or fatalities (if it already has not). Please act!.

Recurring problem. Intermittent problem. Engine hesitates between 1000 and 2500 rpm. Causes unexpectedly poor acceleration from a stop. Causes unresponsive throttle. Causes transmission overshifts (shifting 2-3 gears lower). Causes unsafe driving conditions when acceleration is less than anticipated.
