Hesitates during acceleration. I have reviewed numerous complaints online with similar complaints. When accelerating from a stopped position the engine hesitates around 2000 RPM. It hesitates to a point where it is a safety issue. How many complaints have to be received before nhsta acts? It has been like this since I have owned it. Took it to the dealer - initially they said there was a computer patch. Still hesitating.

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 federal safety agency regarding this complaint!

On 2/9/17, I had the steering recall work performed. On my way home while making a right, steering completely locked. I crossed into the opposite lane until the steering freed up. I drove a few more days without issue but I did notice a knocking sound coming from the front. The following week there were a few times where the steering did not immediately respond. On 2/22/17, I went back to the dealer and they said that they could not duplicate, but they did secure a loose front fog light to fix the knocking. I picked up the trunk and initially did not hear any more knocking; however, the knocking was still there when on rough surfaces. I continued to experience the knocking and subtle issues where the steering did not immediately respond when corning. Around march 18th, I again started to experience the locking. On march 20th, it happened approximately 20 times or more. On 3/22/17, I was back at the dealer where they were able to reproduce the issue. I was told that there were no codes in the system and I saw no lights on the dash. This time the performed the following: "33967 steering assist motor binding, high effort 3.20 no dtc, scan data normal, circuit test normal, replaced steering gear, perform epscm set up, perform front end alignment. Verify repairs". On 3/23,17, I picked up my truck and it seemed as good as new. Even the knocking went away. On 4/2/17, I experienced 2 times back to back in a parking lot where the steering locked and I came close to hitting a parked car. On 4/3/17, on my way to the dealer, it again locked. Turning into the dealer parking lot, there was the subtle hesitation. The tech drove it and could not make it happen. I then went with the tech and I could not make it happen in the 15 minutes we were out. At this point, I'm not sure when it will happen again and I feel that this has been and is a safety issue.

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.

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.

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.

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.
