On february 21, 2017 while making a right turn, my 2016 chevrolet colorado 4wd crew cab turned itself off. On february 22, 2017 richard lucas chevrolet looked at the vehicle for 5 hours an drove the vehicle around several times and were "unable to duplicate concern." I was told to call back if the issue ever popped up again, but it was believed to be unlikely. March 28, 2017 while driving home from work, my colorado ignition made a click noise, and the ignition key turned itself off yet again. This time around was much different than the first occurrence as I had no brakes to stop the vehicle. To stop the vehicle I had to shift into park which I was able to do. Vehicle will be returning to the richard lucas auto center to be reevaluated. On the first occurrence the vehicle was in motion on a county road while completing a turn and the second time it happened while going straight on a residential street.
2016 Chevrolet Colorado engine complaints
Page 3 of 3: complaints 41 to 50 of 50, newest first, as owners wrote them.
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.
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.
Tl* the contact owns a 2016 chevrolet colorado. The contact stated that while driving approximately 70 MPH, a loud popping noise came from the engine area before the speed suddenly decreased to 40 MPH. During the failure, the steering assist, stabilitrak, four wheel drive and trailer braking system warning lights illuminated. The failure had occurred on multiple occasions. The vehicle was taken to the dealer but the failure was unable to be duplicated. The vehicle was not repaired. The manufacturer was notified. The failure mileage was 5,700. Updated 02/03/17
2,400 miles and this vehicle has been back to the dealer four times for "chugging and shuttering" in heavy traffic. Driving though an intersection with heavy traffic it will not keep up with traffic but tends to bog down almost getting rear ended from behind. If you try to smoothly accelerate it will rapidly downshift and jump forward almost rear ending any vehicle in front. Very unsafe to drive. Trying to drive with the flow of traffic at 35-40 MPH the truck shutters as if the spark plugs are worn out. Also trying to accelerate into on coming traffic it will sometimes chug to where you wonder if it's going make make the merge. Very frustrating to drive for a brand new truck, the dealer replaced the torque converter at 500 miles, then has preformed service bulletin #pip5342b three times with absolutely no improvement. Gm states in the bulletin "note: preforming this calibration update may not totally address the shudder or chugging concerns" how can new vehicles continue to be sold with this known problem? Not only is it frustrating trying to drive smoothly, but it is also a safety concern. Due to the poor performance the mileage is about 13 mpg in city traffic, not even close to the mileage rating of 17 mpg.
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.
--- "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 1,500 miles on it. This condition has been present since the truck was new and the severity varies with truck speed and road inclination. The situation has been reported to the dealer and to chevrolet customer service. No corrective actions have yet to be made."
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 the federal safety agency 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!
Engine seems to lag under quick acceleration. Problem occurs most often when accelerating from a turn or when changing lanes under acceleration. Speeds of occurrence mostly approximately 20-25 MPH. Requested checks and service at a dealership only to be given a service bulletin from gm stating this was a normal part of the traction management system. My previous vehicle (2014 silverado) was also listed on the bulletin, but the problem was never noticed on this vehicle. I see this issue as an increased risk of a collision with the highest risk being a rear end collision. This needs to be addressed and fixed.
Driving at about 60 miles a hour and lost all power engine was running but going no were all light were lite on dash like you turn key on before starting thank god no one was coming the other way or the car behind me would have hit me. He was a good driver. Shut it off and restarted it then it would run with all light on dash even brake light and anti skid light and it said on infro. Running at reduced speed. Drove to my home a slow speed it let me. Shut it down let it sit a few min. Restarted it still the same. Shut it down for about ten mim. Restarted it. Seem to run ok but check engine light is till on now I afraid the will just reset it and say it is ok. And next time I won't be so lucky. It has 5500 miles on it. I did see my life before my eyes hopping it dose not happen to others. Taking dealer tomorrow it happen at about 5pm 3/24/2016
