Steering: sudden loss of power steering. Dis display says check stable trak transmission: has a problem with request for downshift.
Power steering issue, internal torque sensor faulting, stabilitrak error, abs error.
Power steering assist is occasionally lost and makes vehicles hard to manuver. If the car is turned off and restarted the problem is momentarily fixed but happens again at random.
Sluggish or chattering, shaking transmission, at slow speeds.
The contact owns a 2015 Chevrolet Colorado. The contact stated that while driving at 35 mph the power steering became inoperable and the vehicle was difficulty to steer. The contact stated that he was able to safely drive the vehicle to his residence. The vehicle was taken to an independent mechanic where it was diagnosed with power steering unit failure and needed replaced, however the vehicle was not repaired. The contact stated that in 2016 the vehicle was serviced for a safety recall for the power steering unit and the failure had reoccurred. The manufacturer was made aware of the failure but provided no assistance. . The failure mileage was approximately 96,000.
Transmision in this vehicle is the worst,and could be dangerous for novice drivers. I've read plaged problems with these vehicles and transmissions after I purchased it. Transmision jerky,shutters. You go to take off and it switches in to low gears too soon and causes the vehicle to vibrate. Sometimes slips between 4th and 5th gear. Also when giving a little bit of throttle sometimes vehicle acts like your flooring it,in rainy or icy weather can cause back wheels to spin causing fish tailing. Had it happen couple times. I've read torque converter problems,and some under a campaign have been replaced. This vehicle has low mileage for a 2015 (83,000).
Transmission slippage, shudder at low rates and high rates of speed.
The contact owns a 2015 Chevrolet Colorado. The contact stated while driving approximately 40 mph, the vehicle would not shift correctly. The contact stated that there was no warning light illuminated. The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure and was awaiting a response. The failure mileage was approximately 51,400.
Transmission begins to buck at low speeds. It’s as if transmission does not know what gear to be placed in. Would have to give it gas from keeping it from shaking the hole car.
Key has been sticking in ignition, unable to remove. Ive kept the key in the ignition and the battery has needed jumped. Dealer tells me this is a very common problem on chevy Colorados from 2015 and 2016 as I have now discovered on multiple chevy forums.
Dash lights for abs, traction control, and stabilitrac go on and off I had it in to the dealership before they said it was nothing it back and I am bringing it in again . I read online that there was a recall but only for certain regions also read this is happening in other areas like with me. Seems dangerous with brakes and traction control and stability. It happens while I am on the road would hate to have myself or someone else hurt if there is something wrong.
Tl the contact owns a 2015 Chevrolet Colorado. After parking the vehicle, the key would not rotate completely to shut the vehicle off nor could the key be removed from the ignition switch. The driver had to jiggle or reposition the shift lever in order to remove the key from the ignition switch. The vehicle was taken to the local dealer (h & h Chevrolet, 730 e. King st. , shippensburg, PA) where it was diagnosed that the transmission control lever knob was not fully seated during manufacturing of the vehicle and needed to be repaired. The vehicle was repaired. The manufacturer was not notified. The failure mileage was 15,000.
Back in early 2018 prior to my bumper to bumper expiring, I had the check power steering and stabilitrak come on on dic. I took it to dealer but they stated could not find any issues. This keeps happening but everytime I turn truck off and then back on as stated in owner's manual, problem goes away. More recent past week, it has been happenings again but more frequent to which at times, turning off and waiting then turning back on, the problem persists. This problem happens various times (while driving city, highway, as I'm turning vehicle on for first time in the day, while backing up, while parking). I have mentioned and taken in to dealer or other places but no codes are found and problem cannot be duplicated.
Transmission not shifting correctly, hunts for gears and wont downshift under acceleration.
This vehicle was purchased October 31, 2016 as a certified pre owned with 17,900 miles on the odometer. From day one, the transmission (automatic v6) has shifted poorly. It is sluggish on acceleration and requires pushing the pedal to the floor to get it to upshift. And when it finally does, it skips a gear and raises the rpms to over 4,000. When coasting down in incline, the tansmission will arbitrarily downshift itself and will occasionally skip a gear, again causing excessive rpms. Neither the dealer nor gm has a remedy for this problem, although the dealer has admitted that there have been several complaints for the same issue from other people who have purchased Colorados. It appears to have all the classic signs of a bad design! hopefully, gm will offer a fix to the problem before someone gets seriously hurt or worse!.
Similar to other complaints, the vehicle nearly stalls when taking off from a stop. The transmission is in the wrong gear and the acceleration is very limited unless the gas pedal is pushed down fully. This causes a very dangerous situation particularly when turning left at intersections as the vehicle will nearly stall or move at a very slow pace. This has been happening since day 1.
Hesitation when acelarating bad almost got in wreck took to chevy dealer they know about it would not do anything about it only has 9050 miles on it. In motion.
The contact owns a 2015 Chevrolet Colorado. While driving various speeds, the accelerator pedal was depressed but the vehicle hesitated before accelerating. The failure recurred on numerous occasions. The vehicle was taken to a dealer where it was diagnosed that the vehicle functioned as intended. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 6,000.
The contact owns a 2015 Chevrolet Colorado. While driving uphill, the vehicle began to jerk forward independently without warning. During the failure, the transmission jumped in and out of gear. The vehicle was taken to a dealer, but the cause of the failure could not be determined. The dealer stated that the vehicle could not be repaired because no failure codes were generated. The manufacturer was notified of the failure. Chevrolet assigned an investigator to diagnose the vehicle, but the failure could not be duplicated. The contact mentioned that the recurrence of the failure caused her extreme neck pain. The failure mileage was approximately 28,000.
When driving at low speeds, it feels like the transmission is in the wrong gear, because when you need a fast acceleration, the car bucks and almost feels like it's going to stall. It seems like it is searching for the right gear and therefore it takes time to react. I have been on a few close calls, almost got into an accident a couple of times because of this bucking and delay on reacting when you need to get the power from the engine.
Like many of the other complaints listed for this vehicle. This problem routinely and repeatedly occurs on both street and highway driving. After slowing down and depressing the accelerator, the automatic transmission will stumble and hesitate. Because the vehicle won't readily accelerate, the gas peddle is depressed further and then the automatic transmission will downshift too many gears and excessive acceleration and engine rpm follows. This problem causes excessive acceleration, which could place the vehicle and its occupants into an unsafe traffic situation and potentially cause accident and/or injury. The dealer service writer was asked about this situation and responded that "the transmission was seeking the best gear to maximize gasoline mileage performance", which really doesn't seem to make sense in this situation.
When slowing down and then accelerating afterward while in traffic the vehicle does not down shift to the correct gear. The vehicle will then sputter and will be very sluggish to accelerate. This happens while in motion as well as from a complete stop. I was nearly rear ended while making a right turn into traffic and the truck would not find the correct gear and thus would not accelerate enough to get out of the way from oncoming traffic. Several times I thought that the truck was going to kill because it was sputtering so much when in the incorrect gear. Truck also wobbles more than usual when turning and makes a popping sound in a turn. Also, radio acts like it has a mind of its own. Navigation will go haywire as if someone is touching the screen, but no one is touching it. Radio will change channels on its own and volume will increase and decrease without any driver input.
When driving my 2015 Colorado z71 4x4 with the v6, in city traffic, you try to speed up slightly so you depress the throttle and the truck doesn't go any faster, then the truck will downshift two gears, lurch forward at high rpm's nearly striking the vehicle in front of you. The engine also spark knocks when up shifting in all gears. Took it to dealership and was told, gm engineers were aware of the problem and working on it, it appears they fixed it with the 2017 Colorado as they put a different engine and 8 speed transmission in the new trucks. If there was nothing wrong with the original power plant and transmission why would they change especially since the new engine transmission doesn't get any better mileage. Also, when driving at highway speed, 75 mph the truck downshifts on it's own, the rpm's go almost to redline and if someones in back of you, you almost get rear ended. Gm says that the transmission is learning, really at 17000 miles its still learning. There is a significant problem with the shift pattern and timing with the engine on this truck. The spark knock and transmission issues have been going on since the truck was new.
When starting up a hill, at a slow speed, the transmission, will hesitate, almost stop, until the gas pedal is pushed down to get the vehicle moving. This is an ongoing problem, I have been told by dealer, that the transmission is adapting to my driving style, and will soon improve.
When stopped or maintaining a low speed (e. G. In traffic) when the accelerator is slightly pressed the truck will hesitate and have a slight jerking motion. Will need to almost full press the accelerator to get the truck moving. Brought the truck to the dealer on 3 separate occasions just for them to say that there is nothing wrong and that hesitation & jerking is ¿normal¿. The ¿normal¿ diagnosis drove me to do some research on this issue and come to find out that other people with the same make, model, year are having the same issues. I have noticed this issue since I had purchased the vehicle back in August 2015.
Purchased 2015 Colorado in August. While driving it I have noticed there is a problem with the transmission and engine synchronization between down shifting and maintaining proper rpm's. When driving a steady speed in traffic and you need to speed up a little the transmission does not down shift. When you give it gas to speed up the engine the rpms are to low and the engine bucks and is lugging very badly. You are at a point it feels like it will stall. This lugging has to be bad for engine. If you press down harder on the accelerator the transmission will down shift suddenly and the truck will surge forward quickly. I have almost run into the rear of vehicles while in traffic and trying to maintain flow speed.
While stopped and trying to turn left on a busy highway I was hit from behind by a driver who did not see me until it was to late. I saw him in my rear view mirror, however, barreling down at me at a high rate of speed. I hit the gas to the floor trying to get away from him but my 2015 v6 Colorado hesitated for a 1/2 second or 1 second, I don't know. It seemed like forever. It then kicked in and we got about 100' before he slammed into the right rear bumper. The impact drove the Colorado forward about 10' and killed the engine. My wife and I both hit the back of our seats and bounced forward and the seat belts caught us. Just prior to the hit, I was leaning forward and thus bounced hard against the seat and then bounced hard against the seat belts; seemingly in a very small fraction of a second. It been a year now and I still have whiplash symptoms. My wife was already leaning back against her seat and apparently did not suffer any whiplash. The car that hit me was totaled but the 80 year old occupant was just shaken up. He left about 30' of skid marks and was trying to get around me to the right. If the Colorado had not hesitated, I am confident he would missed me. The hit was so hard because he hit the the Colorado's tow bar which did not bend much thus transmitting most of the force to the rest of the vehicle. For a fraction of a second, acceleration was intense. I complained to the local gm dealer but they told me the hesitation was designed into the vehicle and they would not "fix" it.
Truck transmission does not down shift when slowing down at times or when taking off from a stop light. Returned to dealer twice and second time they did a software update but still doing same problem. Dealer say's truck normal. Waiting for an accident because transmission will not shift correctly also not shifting correctly at times when passing other vehicles.
Purchased 2015 Colorado July 2015. We had it in for oil changes & a few times regarding hesitation of acceleration. Service techs did not type complaint when in for oil change only when brought in specifically for acceleration issue. They stated it was our fault we did not read the work order. It is not my job to read a work order it's the service techs job to enter every complaint or issue addressed by the customer. The last service was when I spoke to sales manager who set me up with service manager & I was assured me a tech would drive vehicle for a week to and from dealership approx 40 miles per day so they could diagnose the issues. I had advised issue is intermittent; the reason they could never duplicate while in for service. They made sure to state it was running to manufacturer specs. They drove it 10 miles not 40 miles a day for the 7 days they had it. Then said exactly that it was running to manufacturer specs. Of course it did, you did not do what you promised wasting my time & kept my vehicle for 7 days just to pacify me. I told the sales manager what happened who I purchased the 2015 Colorado & my 2014 camaro that I would never buy another chevy product as they would not stand by this issue, their customer or the lemon law. Today my husband is in austin texas with his truck in the shop again as truck now has a service engine light on; of course still has the acceleration issues as that was never addressed or fixed. We have to pay $800. 00 to fix engine issues on a 2015 vehicle, this time no warranty even though we thought we were given a 75k warranty when we purchased the vehicle. This is the only thing I can think of doing prior to retaining an attorney to fight for the lemon law for a vehicle we bought for 40k. We have had issues with this vehicle since purchase & I am hoping I will get a call from someone from the NHTSA regarding this complaint!.
Vehicle bucks and hesitates when pressing gas pedal riding in 6th gear at speeds up to 50mph. If you give it gas it gets worse and finally after 5 secs it will down shift 2 or 3 gears and go way to fast. I have taken it to dealer twice and they said transmition was still in learning mode and should clear up. Well its at 15,000 miles and still has problem. If I put it tow mode it does not happen. . . Shift point calibration is needed badly on this truck.
Colorado has a great deal of hesitation at low speed when acceleration is applied. Vehicle lurches, shrugs, spark knocks, has delayed throttle response. . . . Seems to "chug" until a heavy throttle is applied, then the vehicle "jumps" to a gear/rpm. Very dangerous when trying to accelerate normally and "get out of the way" of other traffic or just climb a slight incline. Chevrolet dealership says this is "normal". This may be normal for Chevrolet, but it certainly is not acceptable for the consumer that wants a responsive throttle when acceleration is required. . . . . . This has been an on-going issue with the truck since it was purchased new in April 2015.
The contact owns a 2015 Chevrolet Colorado. While driving 20 mph and downshifting in manual mode, the vehicle lunged forward. The vehicle was taken to the dealer to be diagnosed. The contact was informed that the vehicle was functioning as designed. The contact also stated that the access door sensors failed. The vehicle was not repaired. The manufacturer was notified of the failures. The approximate failure mileage was 90.
Transmission does not downshift when rpm's fall to 1000 due to slowing traffic, turning, etc. When trying to accelerate normally vehicle lugs and hesitates and will not accelerate. If throttle is significantly increased the transmission downshifts several gears and accelerates rapidly. The higher the load on the vehicle (ie. A/c or going uphill) and the higher the ambient temperature the worse the problem gets. When cruise control in engaged the vehicle will slow down as much as 4 mph before downshifting to maintain set speed. This is a safety hazard due to lack of acceleration when required and also sudden rapid acceleration when vehicle finally does downshift. General motors engineering states that this is due to design to increase fuel mileage and refuses to address the problem. This problem has been present since I purchased the vehicle new in April of 2015.
Similar to other complaints, the vehicle nearly stalls when taking off from a stop. The transmission is in the wrong gear and the acceleration is very limited unless the gas pedal is pushed down fully. This causes a very dangerous situation particularly when turning left at intersections as the vehicle will nearly stall or move at a very slow pace.
The transmission won't downshift while trying to accelerate after slowing down. The truck will start to very noticeably chug and jerk and not want to go from not downshifting when braking and then trying to accelerate. I have been close to getting rear ended when this happens and to avoid it I have to stomp on the gas pedal which then causes it to jerk erratically from downshifting too far and causing me to accelerate too fast and almost rear ending the vehicle in front of me. This happens every time I slow down to go around someone turning or slowing down to stopped traffic and then accelerating again. While driving with my wife at around the 200 mile mark it started chugging badly and she thought we were breaking down. It is very embarrassing when someone is riding with me because no vehicle should act like this. Gm should be ashamed of themselves. I have about 10,500 miles on my truck right now and this issue has been a serious issue since I drove it off the lot brand new. Took it to the dealer and they said it should take a couple seconds to shift from gear to gear. Its funny because I have driven a lot of vehicles and none of them have done that or took that long to shift. I know the transmission is supposed to adapt to your driving. . . Which seems very unnecessary to me but obviously it is not working out for the Colorados. Adaptive transmissions need to go and put a firm sporty shifting transmission in these trucks.
