After coming to a complete stop, the transmission does not drop into 1st gear. When starting from a stop, the transmission kicks into gear very hard, causing a loud noise and causing the driver and passengers to have their necks jerked back, very hard. This problem was present from the time I pulled it off the lot with 4 miles on it. I have taken it back to the dealer, only to be told they can't find anything. This problem occurs every time the truck is driven at nearly ever stop I make. The rear brakes pads are wearing out 3 times faster, than the front pads. I have never had to change rear brakes in a vehicle, but the Chevy Colorado has an issue with rear brakes wearing very quickly.

Transmission does a slight kick before shifting at speeds between 20-45 mph on streets and highways. Girlfriends sister-in-law experienced same problem with her vehicle. Her paperwork when she got her car back referenced Chevy's bulletin# 18-na-091

Transmission is shuddering when accelerating. This shuddering event began around 9,000 miles and has progressively worsened. Service bulletin 18-na-355 has been published but with mixed results. Requesting government Agency continues to monitor this as the sudden lurching could potentially put drivers into a dangerous intersection or be unable to accelerate to avoid a hazard. This is a large safety concern and transmissions are expensive to fix/maintain and the cost should be absorbed by the manufacturer as reports of this issue grow and become more widespread.

The 2019 Colorado Z71 I have has been in the shop at the dealer 8 times since March. The transmission shutters while trying to maintain a consistent speed between 40-60 mph. The transmission also slips and jerks when slowing down and reaccelerating. Dealer continues to tell me they can not recreate the issues. It has become so that I do not feel safe allowing my wife to travel in this vehicle. I fear that she will be stranded on the side of the road or involved in an accident because of the issue at hand. This is her primary mode of transportation.

Hard shifting from 1st gear to 2nd gear specially when it is cold or on the first drive. The transmission seems to not engage the second gear and when it does it results in a hard jolt.

- Anaheimc, CA, USA

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.

In motion. 8 speed transmission fails to shift right. It shutters bad.

- Gansevoort, NY, USA

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.

- Park Ridge, IL, USA

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.

- Bardstown, KY, USA

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.

- Saint Charles, IL, USA

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

- Bentonville, VA, USA

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.

- Rolla, MO, USA

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.

- Merrillville, IN, USA

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.
