2016 Chevrolet Colorado: adaptive cruise control problems

Filed Oct 6, 2022 · Transmission · FL

The transmission sucks. It’s jerky, rough, and random. Downshifting from 5th to 4th and 2nd to 1st is rough. Stopping the vehicle can be a pain sometimes because it’s like the truck doesn’t want to stop. Acceleration is very poor, I shouldn’t have to go pedal to floor to accelerate 5+mph while at highway speeds. It shudders, chuggles, and creates a weird deep droning noise when getting up too speed While driving, the engine picks and chooses when to speed up. I press the gas peddle down and have to wait a few seconds before the vehicle responds. I have noticed the vehicle making sounds like it is sputtering almost to the point to seizing all together. Slow and go driving 20-40mph after coasting and trying to accelerate again the transmission bucks, hesitates trying to find a lower gear. It can’t decide which gear to go into and just sputters and chugs until I push the accelerator 1/2 way down or more and it the finds its gear and rockets off. This type of driving is not safe at all. This happens all the time. This is a known gm issue with Colorado/Canyons and GM changed transmissions following years and no support for 2015-16. It sucks at maintaining speeds; even with cruise control. I go up the slightest, and I mean like a 2% grade incline it loses its speed by 2-5 mph. And with cruise control it’ll down shift to get back to the set speed but I go nowhere. Then it’ll downshift again to a lower gear and climbs even higher in RPMs to get up to speed and then cruise control will shut off and I’ll have to manually accelerate.

The transmission is extremely slow to downshift. As you continue to push the gas pedal, it will finally downshift, sometimes two gears, and suddenly accelerate. When on cruise control, you loose about four MPH before it finally downshifts, again sometimes downshifting two gears. In traffic, the car behind you doesn't anticipate the loss of speed and then you suddenly accelerate. It happens at all speeds, but is particularly unsafe at low speeds with the sudden acceleration. This is probably a software problem as the transmission shifts much more normally if you put it in 'tow/haul' mode. The dealer says this is 'normal' and gm calls it ' torque management '. It is especially unsafe in slick conditions or rainy roads. Btw, I have a 2017 impala with the same six speed and v-6, and it does not exhibit this reluctance to downshift. Thank you.

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.

Vehicle has built in feature of hill assist that is overriding driver. Decides to stop or speed up on hills at will and lags and won't register what the driver is doing for quite some time. Hills are very dangerous with this vehicle and gm refuses to address the issue and debug the software to fix it. There are hundreds of complaints and still nothing. It's has created an issue to where I couldn't stop on multiple occasions, and luckily I was able to avoid and vehicles and pull off the road after placing the vehicle in neutral. The only way to override the feature is when you are in cruise control. I have had to shut the vehicle off to gets the engine to stop revving forward and have taken it to dealer multiple times. It is not safe for me or anyone near the truck.

At approx. 3500 miles started experiencing shifting issues. When slowing down transmission wanted to stay in 5th or 6th gear. Attempts to accelerate caused the truck to bog down until it shifted to a lower gear to accelerate again. When in cruise control problem was really bad. Would loose as much as 5-8 MPH before a lower gear was found to maintain speed in hilly conditions. I took vehicle in for its first service at approx. 6000 miles and had dealer check transmission. They remapped shift points to spec software. This was a temporary fix. Issue is slowly returning. I have watched on control panel at transmission oil temp ( truck has trailer towing package etc. This is a cluster feature available.) seems to shift properly until oil reaches 100 degrees plus then issue arrives. Dealer relayed there had only been a tech service bulletin has been to reset map/shift points. Recently pulled my boat with this truck and transmission shifted fine. Really would like this issue fixed because other then this problem really like the truck.

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.

I live in a rural area with moderate hills and many winding roads and tree obscured corners. While driving at a moderate speed (30-40 MPH), I experience problems with the vehicle's ability to downshift from overdrive to address the increasing incline. The vehicle will, despite normal increase in fuel pedal pressure, lose RPM's from approximately 2,000 to 1,000. As it approaches 1,000 RPM, the vehicle begins to "stutter" and "lurch" as the engine tries to cope with the higher gear. There are two "fixes" for this; pushing the gas pedal down firmly, which causes the vehicle to radically down shift and "leap" forward, or to drop the transmission lever to "manual" and manually change gears (without the "leap" seen in the first method). The end result of the non-manual approach is to cause the vehicle to accelerate radically in an environment of obscured corners and uphill driving. I believe this is a dangerous safety problem as the area is swarming with deer, bicyclists, pedestrians, etc. I have also had "stuttering" incidents when accelerating from low speed, to enter traffic, interstate, etc., although these have been intermittent in nature. I have noticed that the vehicle will also radically downshift going downhill without warning and seems to take a long time to up shift once it is on level ground - again an intermittent action. Fortunately no one has been "tailgating" me when this occurs (a common failing of drivers in this area). I have had the vehicle to the dealer twice for the failure to downshift for a hill and they tell me chevrolet does not recognize a problem with the transmission, shifting, etc. A side note: this problem does not exist in cruise control, but use of cruise control on these back roads would not be advisable.
