2015 Chevrolet Colorado Owner Comments

problem #16

  • 100 miles


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.

Had dent repaired on drivers fender, picked up truck from dealer, drove 4 miles home to put in garage. Next morning at 5:30 am discovered truck fire in garage due to electrical wiring harnesses. Extensive damage to garage and garage floor. Extensive damage to truck's electrical and engine area. Dealer told me it is a GM problem. Now dealing with GM legal dept. But this could be a major problem with all 2015/2016 trucks, no warning what so ever prior to incident. Vehicle is a 2015 Colorado not 1 year old with 8300 miles.

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

Truck has 11K miles. When breaking at low speeds, I get a lot of break squeal. This happens driving forward or in reverse. Also, when driving the truck has a hard time shifting and makes a rattling/pinging noise when it is trying to find the correct gear. This happens sporadically when driving slow, fast, uphill, and mostly occurs during acceleration. The shifting issue happens on the freeway as well as city streets.

When I slow down or come to a stop at a red light. The truck starts stalling and doesnt want to go unless I stomp on the gas. I have taken it twice to a Chevrolet dealer near where I live. First time they said they had to do something to the computer. Second time they said nothing was wrong and I didnt even get any paperwork to show I had taken it to them. It is still doing it.

Turn turns off - truck idles low and feels like it is going to stall when in traffic on the freeway and at a red lights.- I was sitting at a red light and when it turned green and I pushed the gas peddle it did not move. It had turned off. I put it in park and was able to restart it but at least 2 times a day I have to put it in park and push the gas while waiting at a red light so it doesn't turn off.

Engine stalls intermittently when beginning to accelerate from red light/stop sign. Stalls occurred within 1 mile distance from where vehicle was started. First stall was at red light moving forward lightly. Sifted the vehicle to park, turned key, vehicle turned over and was able to drive once put in park. The vehicle was immediately taken to the Chevy service center. The service advisor was able to read an error code P0506 even though the check engine light was not illuminated. Chevy could not schedule an appointment for the vehicle until 5 days later; the error had cleared and they were unable to duplicate the problem. Service department declared vehicle safe to drive as it the issue couldn't be duplicated. Engine stalled a second time when beginning to cross road at a two-way stop with oncoming traffic. Shifted vehicle to park, turned truck back on, shifted to drive and was able to move from intersection without being hit.. the Colorado was taken to the dealership a few hours later and the error code had cleared already. Service advisor stated the car was safe to drive and there was no work to be done as their were no warning codes and the check engine light was not illuminated.

Engine intermittently idles rough and stalls. Engine stalled while stopped in intersection necessitating a restart. Placed car into neutral, restarted, and was able to exit the intersection but after light turned red. Dealer has not been able to duplicate or diagnose the problem despite two attempts.

Sluggish engine after slowing down and then trying to increase speed, engine jumps and hesitates for a few seconds then if you stomp on the gas pedal it downshifts and takes off after reving to about 5,000 rpms. This usually happens when slowing down to about 20-30 mph then starting to increase speed. It is truly embarrassing owning this $37,0000 truck. Dealership and GM customer service stated that the engine needs to learn how I drive and adapt. Really? the engine is remaining in too high of a gear and not downshifting and supplying the engine power that is required in traffic. This problem has existed since I purchased the vehicle 11/1/14, I've ignored the problem hoping it would go away but here I am.

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.

I wanted to reach out to you on Chevrolet"S claim that their engine achieves 305 horsepower. While it may be true that their engine achieves this figure it does so at a stated 6800 RPM. The 6800 figure is important to note because the trucks? red line indicating potential dangerous operating conditions start at 6500 RPM. So in essence in order for an owner to achieve 305 hp they would have to be operating their truck in a potentially dangerous manner. Even in the 2015 Colorado owner?S manual it indicates the danger of operating above the redline? ?do not operate the engine with the RPM?S in the warning area.? GM is stating that someone can achieve maximum hp only by operating the vehicle in a dangerous manner....really"! I believe it will only be fair for Chevrolet to re-evaluate their maximum horsepower prior to their engine hitting the redline.
