2020 Chevrolet Colorado — Known Issues & Recalls

Your transmission started shifting harshly and felt delayed when engaging, eventually losing power and struggling to move the vehicle forward reliably. This created a safety risk because you experienced unexpected loss of acceleration and unpredictable behavior while driving in traffic, with no warning lights alerting you beforehand. You maintained the vehicle according to Chevrolet's recommendations, and the problem worsened over time until the dealer confirmed it was a transmission defect. The transmission and its internal components will likely need to be rebuilt or replaced by a qualified technician.

Your truck shudders and makes loud noises when shifting into gear, and while driving it shudders hard and skips gears. You've had this issue since purchase at 47k miles and have maintained the truck regularly, but GM won't help because your warranty has expired. The transmission likely needs inspection or repair, which may involve transmission fluid service, filter replacement, or internal transmission work.

After having your transmission serviced, the shop told you the transmission was failing and quoted $8,000 for repair. You may want to get a second opinion from another transmission specialist before committing to this expensive repair, as diagnostic findings can vary between shops.

Your truck is making a grinding noise and vibration in the rear end at all speeds, and the transmission is jerking when shifting gears. Your mechanic says a Chevrolet service bulletin exists for this issue, though the truck is out of warranty and Chevrolet reportedly won't cover it. A Chevrolet dealer is currently inspecting the vehicle. If either component fails completely, it could cause loss of vehicle control.

Your truck's transmission shudders, likely due to a problem with the torque converter. Even after spending $800 on a dealer-recommended transmission fluid flush, the shuddering persists. This issue may worsen over time and could eventually require replacing the torque converter or performing more extensive transmission repairs.

Your vehicle vibrates and shakes when accelerating, feeling like you're driving over a rippled road surface. The dealer diagnosed that transmission fluid wasn't heating up properly, causing condensation buildup inside the transmission. The dealer added new transmission fluid and recommended driving 200-400 miles to clear out the moisture.

Your truck's torque converter (part of the transmission system that transfers power from the engine) failed at around 92,000 miles, even though you've kept up with all scheduled maintenance. The torque converter will likely need to be replaced or rebuilt to restore proper transmission operation.

Your transmission shudders and vibrates while accelerating, especially at highway speeds but also at speeds as low as 35 mph. The shaking happens consistently every time you drive, and occasionally it's severe enough to shake the entire truck. A transmission fluid change or transmission service may help resolve this issue.

Your transmission shudders and vibrates after the fluid heats up during normal driving. The dealer says a fluid flush is a temporary fix, but GM has no permanent solution available. You're concerned this could cause an accident, especially with inexperienced drivers, and worry about what happens when your warranty expires and the problem continues. Addressing this may require a transmission fluid flush and filter replacement, or potentially more extensive transmission service.

Your truck starts shaking noticeably between 45-60 MPH, feeling like you're driving on a rough washboard road. You also notice the transmission shifts hard and bogs down when moving from 1st to 2nd gear. The dealer initially performed a transmission flush based on a technical service bulletin, but the problem returned within months. After multiple visits where the dealer couldn't reproduce the issue, they determined the torque converter needs replacement. The repair will likely involve removing and replacing the torque converter inside the transmission.

Your transmission shudders and shakes, and the vehicle almost stalls while driving. This is happening at 60,292 miles. The issue may require transmission fluid replacement, a transmission filter change, or internal transmission repair depending on the root cause.

Your check engine light is on, and a mechanic diagnosed a faulty camshaft position sensor that needs to be replaced. You've notified the dealer and Chevrolet, but they won't help because your vehicle isn't covered under an extended warranty. The sensor replacement will involve removing engine covers and swapping out the failed sensor.

While driving at 70 MPH, your check engine light came on and your truck lost power. A mechanic diagnosed a failed exhaust camshaft position actuator. Your dealer confirmed this diagnosis but wouldn't repair it because there's no recall on file. The problem happened at about 67,000 miles. Fixing this will likely require replacing the camshaft position actuator and possibly related sensors.

Your check engine light came on due to a faulty camshaft position actuator. Your mechanic replaced the VVT solenoids and confirmed the actuator itself needs replacement. GM has issued a technical service bulletin for this exact problem on your truck's year and model, but your vehicle's VIN doesn't qualify for the recall. Fixing this will likely involve replacing the camshaft position actuator.

Your truck jumps or misses when it reaches certain speeds above 60 mph, feeling like the brakes are sticking and cutting power to the vehicle. The problem is getting worse over time. A technician has indicated this may be related to the transmission or torque converter failing. This will likely require a transmission inspection and possibly torque converter replacement or transmission service.

Your brake booster failed without warning while you were driving slowly in a parking lot, causing your brake pedal to go completely to the floor with no stopping power. You had to shift into park while moving to avoid hitting pedestrians. The fix will likely involve replacing the brake booster, a component that helps amplify your braking power.

While driving on the highway at 65-70 mph, your truck suddenly started slowing down on its own, and your brake pedal became hard and unresponsive. You had to use the emergency brake to get home safely. The dealer suspects a faulty vacuum pump may be causing the issue, which affects both your braking system and forward collision avoidance system.

Your airbag warning light has been flickering on and off intermittently for nearly 2 years. You've taken your truck to the dealer multiple times, but they couldn't reproduce the problem, and an independent mechanic was also unable to fix it. The fix will likely require diagnosing the airbag system's electrical connections or control module to find and repair the intermittent fault.

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.

Your third brake light (the one in the center of your rear window) has a faulty seal that's allowing water to seep in. This moisture is corroding the electrical connections inside, causing the light to stop working. The fix will likely involve replacing the brake light assembly and sealing it properly to prevent future water intrusion.
