The transmission surges causing the truck to lunge forward when starting from a stop. The key will not turn completely off allowing the key to be removed. Both events occur occasionally so if the dealer says it did not happen to them then there is nothing they can do. Both things are being reported on the internet by numerous people. Both things are safety hazards.
2019 Chevrolet Colorado transmission complaints
Page 3 of 3: complaints 41 to 66 of 66, newest first, as owners wrote them.
In motion. 8 speed transmission fails to shift right . It shutters bad.
Shuttering/shaking when shifting gears while in motion speeds from 10mph to 80mph. More so in stop and go traffic on the highway or city street. Harsh down shift when coming to a stop.
The transmission causes the truck to shutter when on a slight incline or under slight pressure/strain. Occasionally the truck shift very hard. I'm concerned that the transmission wont last and it causes a terrible ride.
The transmission has a delayed downshift, causing the truck jump forward during a stop. When coming to a stop, it feels like the truck is being hit from behind, at the same time, making a loud mechanical noise. Sometimes it hits so hard, it will cause the truck to be thrown past my driveway, while preparing to turn into the driveway. It was recommended that the factory transmission fluid be replaced with a thicker fluid, so I took it to the dealership and had that done. Although it fixed the previous issue of vibration, caused from the transmission switching back and fourth between gears rapidly, but it did not fix the hard and delayed downshift. This has been an issue from the moment I pulled it off the lot, with only 4 miles on the odometer. The truck was immediately returned to the dealership, in which they said they could find nothing wrong with it.
Bought 6 months ago 7000 miles. When driving felt like I driving over rumble strips, I took if to the dealer and they claim that was normal. They changed the fluid and said drive it for 500 miles. Now I took it back again because every time I start it and there is a bang in the transmission, they wanted me to leave it and refused to give me a loaner vehicle. They told me don't worry about you have a 5 year warranty on you drive train. Told them me and my wife were going on vacation and they didn't seem to care. I am very disgusted with this purchase I made. Wouldn't recommend this vehicle to anyone.
2019 chevy colorado zr2- shutters or hesitates before shifting up at 5 / 45 / 65 MPH. Feels like you did not press the gas when accelerating. It is intermittent, so therefore very hard to duplicate for the dealership. Three times to the dealer. #1 tranny flush #2 reprogrammed the tranny #3 sorry ma'am we can't duplicate what you are experiencing. I live in michigan on those 0 degree mornings the truck barely wants to get going. Dealership says 'this is normal with an 8 speed transmission.' I told the dealership I have owned a lot of cars and none have had this problem. Occasionally it lunges forward when coming to a stop- this is so dangerous as I drive in the city everyday. Very expensive problem to have.
2019 chevrolet colorado z71 4x4 vehicle shutters noticeably when in motion on flat roads or uphill. Problem always occurs in all road and environment temps and appears most often in moving operation of 45 to 65 MPH.
The transmission slips, bangs into gear when cold. The dealer is telling me this is normal, based from a bulletin from gm. I bought the truck with a 112 miles on it, the trasmission has slipped from the very first day.
Chevrolet 2019 colorado - experiencing slipping on transmission - feels like driving on rumble strips all the time
Vehicle shutters between the speed of 15mph to 35mph shaking vehicle very bad. Leaking back sliding glass, no sealant around glass dealer had to replace back window new mounding and sealant. Carpet in back is soaked with possibility of mold. Dealer did not make any effort to clean carpet or headliner when rear window was repaired. The headliner had a bad stain and was superficially cleaned, leaving possibility of mold in the future. The carpet and floor mats were not cleaned leaving possibility of mold in the future. Poor service in this area.
Transmission jerks and jumps going up a grade, or when applying power during acceleration. It is like driving on a rumble strip, shudders and vibrates the cab. Have appointment with dealer next week, vehicle was purchased new and has 3600 miles.
I experience harsh shifts from 1-2 gear and when downshifting 2-1. It jolts the whole truck. It sometimes randomly downshifts for no reason when I driving on the highway I am afraid that something is going to fail in the drivetrain when I'm driving.
At highway speeds of about 60-65 MPH the transmission in my 2019 colorado zr2 v6 automatic (the truck has only 5700 miles on it) has a shudder or shaking problem which shakes the whole truck. It also causes a loud low frequency booming noise. When it started happening it was alarming.
Truck vibrates at highway speeds it's like driving on a gravel road
Vehicle lurches forward when rolling up hill to a stop or applying the brake on an uphill stop at low speed or when going uphill at low speed while off road & it lunges hard enough to spin both back wheels on gravel this happens when attempting to pull onto the highway from a gravel driveway
Transmission shudders when accelerating and decelerating. I bought this truck new 1 month ago!!!!
Late down shift ... Shifts hard ... Vehicle lurches forward on a stop
Eight speed transmission shutters and vibrates under normal acceleration. More noticeable on hills or under light load. Chevy dealers answer: they all do it!! After extensive online searcher, I found this problem has been ongoing for 3 to 4 years with numerous complaints and dissatisfied owners! They fail to tell you this when your buying vehicle. Chevy has a technical service bulletin # 16na175 on problem, but will not resolve problem. Of all the vehicles I've owned over the years, I have never had a driveability problem this serious.
. I was at the carwash vacuuming the truck while in drive when I got back to the passenger side to put the hose up, I reached in to remove my keys out of the ignition, and the truck rolled backwards, I ran to the driver side and the door knocked me to the ground and the 2019 colorada ran over my entire body from my feet to my face and head. I suffered a punctured lung and my pelvic bone is fractured in several places. All of this was caught on tape.
After replacing transmission fluid per tsb 19417577 truck occasionally does not come out of gear when slowing down to a point where engine goes under 500 RPM where gas is applied to keep from stalling. This surge while braking under 10 MPH then requires hard press on brake which does seem to drop transmission out of gear with hard clunk. Stopped just inches short at light from car in front of me stopped at light. Dealer can not immediately reproduce with short test drive, and will not even attempt to troubleshoot. Been told to bring back when it happens more often.
Transmission shutters around 25 to 35 miles a hour under load
Tl* the contact owns a 2019 chevrolet colorado. The contact stated that the vehicle was taken to the shop twice for transmission failure. While driving 50 MPH, the contact stated it felt like he was driving over a bunch of speed bumps. Camp chevrolet cadillac (101 e montgomery ave, spokane, wa 99207, (509) 381-2970) removed, inspected, and reinstalled the torque converter during the first visit. During the second visit, the dealer inspected the vehicle and only performed an oil change. The contact called the manufacturer and an inspection appointment was scheduled for april 23, 2019. The failure mileage was 1,100.
Truck began shuddering while driving at 600 miles on the odometer. When the vehicle is accelerating around 40 MPH and roughly 1200 RPM is when it is most noticeable, but can also feel it at hwy speeds 60-75 MPH. Feels like I am driving over speed grooves in the road (best way to describe the shudder when the truck is shifting between gears).
Vehicle transmission seems to late down shift when slowing, causing the vehicle to jump forward once shifting has completed.
While driving at different speeds I get a bad vibration. I have read where a lot of people have this problem with the colorado. Dealer says to wait for a recall. I would like to have it repaired now. I paid over 30,000 for this vehicle and can't drive it the way I would like to. It will loosen every bolt on the vehicle.
