I was told that if it needed done again that i would have to pay to have it done and would cost approximately $400- $500. On 12/13/2024 the truck is shuddering again at 48,700 miles.

• 12/13/2023· POWER TRAIN

  There is a known issue with my truck, where the Transmission will all of a sudden lock up and then it shutters. The truck shakes violently and happens randomly. There is no rhyme or reason why this happens. Of course I'm barely over my warranty and Chevy in Austin states that it will be 3-5 days before they can review my truck. They won't provide a rental car or any help with a rental, so I'm expected to not have a car or figure out something myself to even have my truck looked at. My friend has GMC Canyon (same transmission) and had to have a level two mechanic replace his fluids. There are no warning lights or anything, this is a constant thing that is getting worse. There is a lawsuit in Canada for this issue that Chevy has known about and they haven't done anything about it.

  Check engine light appeared when starting vehicle. Code read by local auto parts store. Thermostat failed at less than 50k miles, causing fan to run constantly and for an extended period time after turning engine off, despite outside temperature. Causes potential for overheating due to not reading temperature. Thermostats are rated to last 100k miles. Is not covered under Chevrolet's 5 years/100k miles powertrain warranty. Upon research, this has been an extremely common issue for Colorado trucks for many years and has not been addressed by Chevrolet. Many blogs are available online. This vehicle was a certified vehicle bought just over 1 years ago and would not be fixed by any warranty according to the dealership purchased from (Bob Fisher).

• 11/04/2024· STEERING

  Within the last 2 months, I have had momentary steering problems at low speed. They continue to become worse with time, no longer safe to drive. Dealer has vehicle now and informs me that it will cost $3000 for a known/existing corrosion of electrical connections in the power steering assembly. Via the internet, the steering gear torque sensor cover assembly needs to be replaced. Because this cover assembly has leaked, the wiring harness also has to be replaced. 7 hours of labor, front end alignment, etc! The loss of power steering in a turn has nearly caused several accidents till I got it home. Dealer confirms what I experienced in test drive, internet has many examples of same problem and solution. There are no warnings of impending loss of control, one minute everything is fine, the next you are fighting for control.

  The component that’s failing on my truck is the Apple car play and a check engine light (CODE P0024) which indicates Exhaust Camshaft Position, Bank 2. My safety and others safety is put at risk while having these issues: 1.) The Apple Car Play, having to take my focus off of driving to try and unplug my phone and plug it back in to HOPEFULLY fix the issue of using the navigation or phone calls while I’m driving during long road trips is extremely dangerous for myself, my loved ones and others on the road around me. 2.) This error code is extremely unsettling to experience while 500 miles away from home and has caused an incredible amount of stress on multiple occasions. The light constantly turns on and off, leaving me completely clueless as to if I’m going to be left stranded on the side of the road. Both issues have been looked at by an automotive repair shop. And I’ve been advised to seek information to if there are any recalls regarding this issue. Check engine lights display for the Exhaust Camshaft Position Bank 2.

  The Automatic 8-Speed Transmission completely deteriorated after 4 years/64,000 miles exactly after the Power Train Warranty. No warning lights or signals identified me of the problem, only a noticeable shuddering when driving at highway speeds. This vehicle is currently at the dealership where they have confirmed I will need a new transmission to replace the faulty original manufacturer's transmission. My safety and others' safety is/was affected by a faulty piece of equipment that was destroyed with regular use. This could potentially lead to my vehicle being unable to shift up/down during traffic leading to an injury or worse.

  Transmission shuttering mostly at interstate speeds but as slow as 35 mph. Under light to medium light pedal acceleration. Truck feels as if it's going over Road ripples. I'm disappointed to find out this is a common problem with Chevy 8-speed Transmissions. It happens every time I drive it. From time to time it'll shake the truck a little violently

• 09/09/2024· POWER TRAIN

  At about 58000 miles my vehicle began to shake violently as I drove it. I initially thought the wheels were out of balance or I had a leaf spring issue. Had both issues looked at and that was not it. Took it to a Chevy dealer who wanted 200 dollars just to look at it. By this time I was just over 60k miles. Did a lot of research online and found that if you had the transmission flushed that would resolve the issue. Had they done and problem solved. Now at 80k miles and it's doing it again. Called Chevrolet dealership who told me it would be 5 weeks, $500 and I should probably call another dealer to see if I could get it in and that is for them to just flush it again. Chevrolet has a well known issue with these transmissions and are not offering any assistance but to try and get you past the 60k mileage where they say not their problem.

• 09/06/2023· UNKNOWN OR OTHER

  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.

• 09/04/2026· SERVICE BRAKES

  On September 4, 2026, I experienced an extremely serious and frightening braking failure while driving my 2020 Chevrolet Colorado 2.5L. I was driving my granddaughter to school and was pulling into the school's carpool/drop-off area at approximately 20 mph. This was an especially dangerous location because children, parents, vehicles, and school personnel were in the immediate area. As I attempted to slow and stop the vehicle, the brake pedal suddenly became extremely hard and the vehicle would not stop normally. The dashboard displayed “Service Brake Assist,” and the check-engine light illuminated. I pressed the brake pedal, but the vehicle continued moving. Realizing that the normal brakes were not stopping the truck, I engaged the emergency/parking brake. The emergency brake slowed the vehicle somewhat, but even then the vehicle did not come to a complete stop. I ultimately had to place the vehicle in PARK to get it stopped. Fortunately, I was traveling at a low speed and was able to prevent the vehicle from striking a child, pedestrian, another vehicle, or other property. My granddaughter was also inside the vehicle at the time. This was an extremely frightening situation that could very easily have resulted in catastrophic injuries or death. The fact that this occurred in a school carpool/drop-off area surrounded by children makes the seriousness of this failure especially concerning. There was no reasonable warning that I was about to lose normal braking assistance. I am reporting this incident because I believe this vehicle may have experienced a serious safety-related defect involving the braking/brake-assist system. I am requesting that this incident be documented and that NHTSA investigate whether other owners of 2020 Chevrolet Colorado vehicles, particularly those equipped with the 2.5L four-cylinder engine, have experienced similar sudden losses of brake assist or braking ability.

  While driving my 2020 Chevrolet Colorado through [XXX], the truck began having difficulty accelerating. As I exited the highway and turned into a gas station, the truck suddenly lost power. The steering became extremely difficult, and I lost normal brake assist. The brake pedal became extremely hard, and I had to apply extreme force to stop the truck and avoid crashing into a wall at the gas station. Fortunately, no collision occurred. The truck was towed to Ed Corley Ford in [XXX] because I was stranded in a remote area with very limited options. They diagnosed a failed/broken vacuum pump and told me replacing it should make the truck operable so I could drive it home to [XXX]. I authorized the repair. After replacing the vacuum pump, they told me they started the truck and heard an abnormal sound. They shut it off, and when they tried to restart it, the truck would not start. They wanted to perform additional diagnosis, but I declined and had the truck transported back to [XXX] for evaluation by a Chevrolet dealership. Huffines Chevrolet Lewisville inspected the truck. Their technician removed the camshaft position sensor and used a borescope to inspect the camshaft. They documented that the camshaft is damaged at the end where it connects to the vacuum pump and stated the actuator pin was most likely bent due to the vacuum-pump failure, damaging the camshaft and causing it to be slightly out of time. I have also been informed of engine damage. The truck remains inoperable and is currently available for inspection. I am concerned this is a safety defect because the vacuum-pump failure resulted in a sudden loss of normal brake assist while I was driving and was followed by camshaft/engine damage. I am asking NHTSA to investigate this failure and similar Chevrolet Colorado complaints. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  The transmission on my 2020 Chevrolet Colorado often jerks when shifting and down shifting. This is especially true in colder temperatures where there is a significant hesitation and jerk when shifting from 1st gear to second gear. This is an automatic transmission. GM is aware of this issue and problem but are not resolving this problem as they indicated it should be acceptable. I have contacted both the dealer and GM. There have been no accidents related to this issue.

  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.

Totally unacceptable for a truck to that is 4 years old to be rotting out. One of the lines is a nightmare to replace because of where it is inserted into the motor.

  Vacuum pump seized, causing loss of power assist on brakes. This happened as I was approaching an intersection to make a right-hand turn. When I press down on the brake pedal it felt hard, like it was locked up. After pressing down on it with both feet, I was able to slow the vehicle down enough to turn out of the intersection. If this event happened when there was another vehicle in the intersection or approaching the intersection on the side street that I was turning onto, it would have led to a collision. Not being able to slow down adequately, I had to swing wide in the turn. This incident happened at a relatively slow speed. If it had happened at highway speeds it could have been catastrophic. There was no warning light prior to the incident the check engine light did not come on until after the incident. The Pump seizure caused the connecting coupling between the exhaust cam and pump to shatter. The damage was extended to the exhaust cam and valve cover and leaving metal fragments in the engine. The local Chevrolet dealer has given me an estimate for the repair of over $2400

  This vehicle suffers from a torque converter/transmission shudder after the transfer mission fluid heats up. My initial complaint to the selling dealer and they did not follow the GM posted procedure and initially charged me for the service. I’ve changed dealerships and I’ve been told it the temporary fix is to do a flush and there is no permanent fix by GM. I have had situations where and unexperienced driver would have definitely got into a car accident and I don’t let anybody drive my car because I believe it is unsafe. So far the dealer has been accommodating while under warranty but advised I reach out to GM who then advised to review my documents I file an NHTSA complaint.

  The ignition key can not be removed after putting the vehicle in park and shutting it off. Many attempts are required to jiggle the shifter switch/steering column/key before it will release on most occasions. This is a common issue, going back years, to 2015. How can it still not be resolved? The safety issue here is one of having your vehicle stolen because you are forced to leave the key in the ignition for all to see; or owners are choosing to disable the steering lock prevention altogether, which has its own set of dangers. GM needs to solve and fix this. So far it sounds like they don't even understand the real problem.
