On the freeway , a 'power steering 'signal turned on . suddenly steering wheel became locked . tires pushed car to the left . brakes , gas , entire truck stalled.vert dangerous and came with no warning.
As i was driving my vehicle home from work, my vehicle lost acceleration and the stabiltrax warning came on. i had to pull off of the highway as fast as i could due to the fact that the speed was 75 and my vehicle was decelerating very quickly. i turned my car off momentarily and it magically became normal other then the check engine light staying on. i only have 41000 miles on my truck, so there is no reason why it should be messing up already! from the looks of the research i have done, this is a common occurrence on this yea,r make, and model of this truck. it runs great some days and causes me to have to pull over multiple times other days. very frustrating!
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.
When driving about 35 mph, and then pressing the gas pedal to accelerate / pass another vehicle, the engine revs up to 4000 ' 5000 rpms, but does not downshift. it then takes a few seconds to go back to 1200-1500 rpm range. it may downshift at that point, and the truck will jerk violently. i took it to the dealer where i bought it new. they said gm is aware of the problem and referred to tsb #pip5547. i took it in again in dec. 2019 before the warranty expired. they had the vehicle for 18 days. they agree there is a problem, but gm has no fix for it. this is a repeatable problem, happen consistently in the 30 to 40 mph range. the manual states that when trying to pass at less than 35 mph, press the accelerator halfway down, as i have done. that is when the engine revs up but does not downshift like it normally should. but then the downshift does occurs while the rpms are coming back down, and the truck jerks violently. this is dangerous because i am unable to reliably pass another vehicle at this speed. also, the same behavior will occur in the 50 to 60 mph range. this is very dangerous when using an on ramp to get on an expressway.

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 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 14,500 miles on it. this condition has been present since the truck was new and the severity varies with truck speed and road inclination.
Tl* the contact owns a 2016 chevrolet colorado. while driving various speeds, the vehicle suddenly hesitated when attempting to accelerate. the vehicle was taken to the dealer (ferman chevrolet of tarbon springs) on several occasions, but the failure could not be duplicated. the manufacturer was not notified of the failure. the failure mileage was 100. updated 08/03/07*lj *tr
I started my colorado to head home, the weather was clear and cool. the "driver information center" in the instrument cluster flashed that the airbag, anti-theft system, and the traction control system (tcs)/stabilitrak were inoperable. the airbag, tcs, and one other lights were illuminated. i turned the vehicle off. waited a few seconds and turned it back on. the same thing happened again. i cleared the warning messages and started to drive to take it in and get it looked at by a certified chevrolet mechanic. i left the parking lot and after entering the nearby street i noticed that the driver information center was not displaying any vehicle information (showing zeros or blanks for all diagnostic information including mileage, fuel, oil pressure, speed etc). also, the needles for the speedometer, tachometer, fuel gauge, and engine coolant temperature gauge were lifeless and reading zeros. only the odometer and "infotainment" system were working correctly. i estimated my speed to be above 30 mph at this point. i immediately pulled off the road, put the vehicle in park and turned it off. i waited a few minutes and scanned the wiring under the hood and steering wheel but could not identify any issues. when i started the vehicle again, all the issues were gone as if nothing happened. seemed kinda like restarting a computer to clear software issues. not sure what could've caused it. my vehicle is a 2016 chevrolet colorado z71 with 27,000 miles on it. it was purchased october 2015.

Tl-contact owns a 2016 chevy colorado... contact stated that hood came open while driving going 5mph pulling out of parking lot.. vehicle shut off five times on five different days. vehicle shuts off going from a complete stop after pressing on gas pedal . vehicle shut off turning onto main highway and would not start back up. hood latch does not stay shut. vehicle was towed to dealership and hood latch was fixed. vehicle was at dealership again a few days ago and dealership stated no recalls on vehicle. dealership also stated vehicle was never in shop for shut off reason. contact advised to contact chevy at 800-222-1020
Engine revs high coming to a stop. required both feet pressed hard on the bakes to emergency stop. speed control quits working then service-stability control comes on, car starts to handle ackwardly, pulls to left then. cut engine off and it resets, but the cruise control stops working and then that service stability control comes back on.if i don't put on the cruise control, i don't get that stability control message so far. braking problem happens when comes to a stop. cruise control happens at highway speeds but sometimes going 45 mph.
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.
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.
