Colorado Z71 V6

  • Automatic transmission
  • 3,535 miles


I was about a half a mile away from my house when all of a sudden I lost all forward gears. I could go in reverse but nothing forward. The dealership had the truck for 29 days. After having back for 4 days the truck started to make another noise when you would drive the truck for the first time. When you put the truck into drive and start to give the truck gas you would get a grinding noise for about 2 to 3 seconds and then it would go away. I am waiting to hear back from the engineer team they are sending down to try and figure out the problem this time. This was the first time I have bought something brand new and will most likely be my last. I love the look of the truck but it has been a major pain in my butt.

Colorado Z71 3.6L V6

  • Automatic transmission
  • 2,500 miles

Bought the Colorado in March to tow a fishing boat. I'm a first time truck and GM owner. Really like the truck. Not fond of the dealership, sales team blunders and communication issues, and their responses for corrective action. So to the problem.... While on a fishing trip, with a 3 hour commute in tow mode to and from the site in Upstate New York, I parked the boat. It sat for an hour. I then went to launch the boat, when put into drive the truck would not move. Felt like it was in neutral. Put it in reverse and backed up. Worked fine. Back to drive, nothing but rev's. Turned truck off, then back on put it in tow mode and I then have forward drive. Very odd. 2500 miles!!! The boat weighs in at 1500 lbs, light for a truck that supposed to be able to tow 7000 lbs. That was just the start of my problems with the transmission. See other post for shifting nightmare. I believe the transmission is a very poor design and not thoroughly tested (under load) by folks at GM. Its shifting while towing is extremely poor with very high rev's until shift point and then once it does shift there a huge lag in power, resulting in a very jerky towing platform, which constantly shifts. In my opinion if you are going to design a transmission that shifts a lot, then it needs to be built with high quality gears and clutching mechanisms. This truck won Motor Trend truck of the year!!! Clearly the criteria was looks versus raw performance (but then again we live in a society that rewards how good something looks on the outside). My buddies, GM owners themselves, had a good laugh on how GM just can't seem to get it right anymore, except for recalls. One buddy was going to recommend his son by a Colorado, he has changed his mind. Will add to post once we find problem. Might be a while.

Colorado Z71 V6

  • Automatic transmission
  • 935 miles

At about 935 miles on April 2nd, I lost all forward gears in my 2015 Z71 Chevy Colorado. As of a week later the Dealer still has it, they found as of yesterday a snap ring came off inside the transmission and took out pistons and clutches in the forward gears. Now they are seeing about getting the parts and getting it back to me.

I loved the truck, and knew nothing was wrong and had no other problems, other then one morning the truck vibrated for a couple minutes. Then the night I lost the forward gears it made a sound like you ran over a plastic soda bottle, then no forward gears. I wondered if the vibration was the start of the transmission problem?

no forward gears

I was driving my 2 year old daughter to daycare when at a very busy intersection I had no forward gears. Now everyone is honking and shooting me the bird. I nice gentleman tows me into a parking lot and another nice lady helps me get my daughter to where she needs to go. OnStar gets a tow truck on its way. Get to the dealer and no one is really that apologetic about the 2015 Motor Trend Truck of the Year leaving me stranded with 4,100 miles on it. It's a Friday and they say they'll look at it Monday and set me up with a rental car. Follow-up the next week, a clutch piston is losing pressure so they will have to disassemble the transmission. Get call the next day, they are replacing the piston and clutch just to be safe. So now I am going to have a truck with 4,100 miles on it and have no confidence driving it more that 50 miles from my house. We'll see how it all works out in the end, but right now I wish I had bought a Tacoma. I have loved the truck to this point.
