2020 Chevrolet Colorado Other Problems

You heard an unusual humming noise coming from the back of your truck that sounded like a spaceship. When you took it to a mechanic, they found metal shavings in the differential fluid and determined the gears were damaged, requiring a complete differential replacement. This is an uncommon failure for vehicles.

IGNITION LOCKED UP. This situation is the same as another complaint posted earlier this year by another owner. Ignition key will not turn in the igntion switch. Tried all the internet fixes. Turning steering wheel, bumping transmission lever, tried spare key, etc. Nothing worked. $225 to tow to the dealer. Still waiting to hear from back from dealer.

GM had sent a letter regarding recall on 2020 Chevy Colorado's Cam shaft in 2/2024. In 11/2023, I had my check engine light on and had the cam shaft issue fixed by my mechanic, before it was a known recall. By law, GM should pay me for the work done on the truck, but GM for the last 2 months have been, what I feel, playing with me and have not paid me. I have sent the required paperwork several times, been on the phone to confirm receipt of the paperwork, and how it looks; each time the customer service representative told me it looks great. Now, for the 3rd time, I had gotten email saying "we never received your paperwork". This is not right for a car manufacture to treat their customers this way and illegally not pay for their recalls.

Ignition Switch/Steering/Transmission??? When I went to start my truck the key would not turn. I tried to jiggle the steering wheel but it was locked up tight. I checked to make sure that it was fully in park and it was. As a last resort I kicked the front tire as the wheel was turned slightly. I tried again to jiggle wheel and turn key, after several attempts key finally turned and started. I moved truck forward straightening wheels then shut truck off and went inside to gather my things to run errands. When I came back out the ignition once again locked up on me. After numerous attempts I was finally able to get the key to engage. When I ran my errands I left the keys in the ignition and in the accessory position instead of fully shutting the engine off. THIS IS MY SAFETY CONCERN 1) My battery could run down leaving me stranded, 2) My truck could be stolen 3) I could have removed the keys and taken the chance that I MAY or MAY NOT have gotten the key to engage again, potentially leaving me stranded with groceries, etc. Dealership cannot get me in for more than a week from now, 9 days actually. It will be a Friday... who knows if they will even get it repaired in one day.

Radio will suddenly stop responding to the controls in the vehicle. Volume will not adjust up or down. Power button will not work. While talking on the phone, the phone will disconnect from the speakers while in use and plugged in. This will require me to retrieve my phone while I'm driving and put it on speaker to continue my conversations.

The backup camera on the vehicle continually gets moisture in it resulting in a very blurry image on the display to the point of the backup camera being unusable at times, especially when it is dark. This creates a safety risk and an increased risk of hitting a moving vehicle or pedestrian when backing up as the vehicle is a pickup truck and has a very large blind spot behind it. We have run over toys in the driveway due to not being able to see them, fortunately no one has been injured as of the time of this writing. I have contacted Cheverolet extensively about the issue since July 2020 and they have been of no assistance. They acknowledged the issue and merely extended my warranty to 2025. A local dealership has replaced the camera a number of times and the issue remains unresolved; it has been replaced by the dealership nine times since 09/30/2020. The issue was first observed in July 2020 and the vehicle was purchased new from Cheverolet in May 2020. The vehicle does not go off-road, is parked in a garage, and replacing the camera has not corrected it. The vehicle was dropped off at the local dealership for approximately one week in May 2023 and the dealer reported that they were unable to replicate the issue. I subsequently reached out to the local dealership again in July and August with photos and videos showing the moisture on the inside of the camera lens and have yet to receive a response.

2020 Chevrolet Colorado: Purchased truck in February 2023 w/25000 miles. Since purchasing truck, key would get stuck in ignition. Key gets stuck in ignition frequently and would take several minutes to release, very frustrating. Was told I was not pushing key in to release. After several months and repeated key release issues, I called dealership and was told problem was due to shifter assembly(connection issue). Appointment made(August 12,2023) and issue confirmed and replacement of shifter assembly done. Was told the Chevrolet Colorado has issues with this problem. GM/Chevrolet should warrant this consistent issue. Out of pocket $471.00... mileage at time of replacement 39,859....

Nov 2021 I took my truck to the dealership with complaints of a high pitch hum coming from the reared- drivetrain. They found metal shavings in the rear end fluid and said they had to rebuild the rear end 11/3/21. Last Thursday I took it back for the same reason. They found alot of metal shavings again 1/19/23.

1)The exhaust system has leaked into the vehicles interior on at least two occasions May 7 2021 and July 24 2021. Arrangements can be made for vehicle inspection. We will be happy to help by any means we can. 2) There were both large amounts of exhaust fumes to the extent that I had to turn off the truck and exit the vehicle iimmediately. I might have died. Fortunately I was already parked so I did not need exit the roadway. It had been a long hot day in the mid to upper 90s I was about to take a brief nap in the vehicle and could have potentially died if I had fallen asleep as I was waiting in the parking lot on my partner to Complete a couple purchases and was anticipating about a 30 to 45 minute wait. The other time happen on May 7 2021 while my partner was driving on the highway by them self. The exhaust fumes were bad enough that all windows had to be rolled down and needed to exit hhhighway for the enext exit to park and exit the vehicle as soon as possible. Partner notes that they saw exhaust smoke/fumes coming iin from the vents with the air conditioner running . 3) The dealer has not been able to reproduce the problem. Vehicle has not been to a independent repair facility for the issue 4) No other inspections have been performed outside of dealership staff. 5) No warning lamps or messeges came on. The amount of exhaust fumes coming into the vechle was not a gradual ooccurrence but a sudden large amount of fumes. We will most likely be driving with the windows down partially, in addition to carrying a home carbon monoxide detector in the vehicle to assist in saving our lives and others on the road and to help document the problem.

WHILE DRIVING THE RADIO WILL GO SUDDENLY TO FULL BLAST WITHOUT REASON. AFTER ABOUT 2-3 SECONDS IT WILL RETURN TO NORMAL VOLUME

WHILE STARTING TO DRIVE THE VEHICLE A GUSHING WATER SOUND IS COMING FROM BEHING THE DASH.

WHILE BEGINNING TO ACCELERATE AFTER STARTING THE VEHICLE, I NOTICEABLE SOUND THAT IS BEST DESCRIBED AS 'WATER RUSHING' IS HEARD FROM BEHIND THE PASSENGER-SIDE DASH AREA. AFTER CONDUCTING SOME RESEARCH I HAVE NARROWED IT DOWN TO THE ISSUE OF AIR TRAPPED IN THE COOLANT SYSTEM. ISSUE IS ISOLATED TO THE AREA OF THE HEATER CORE. HAVE ALSO SEEN MENTIONS OF SERVICE BULLETINS WHERE, IF THE VEHICLE IS UNDER WARRANTY, IT CAN BE BROUGHT IN AND THE TANK CAN BE DRAINED AND REFILLED PROPERLY.
