2023 Chevrolet Colorado Transmission Problems

Your truck is experiencing intermittent electrical failures affecting door locks, power windows, and four-wheel drive controls due to a suspected body control module (BCM) problem. These failures create a safety concern because door locks may not work during an emergency, and the 4WD display malfunction could affect traction control in mountain driving. The issues temporarily resolve when you disconnect and reconnect the battery, but they keep returning with increasing frequency, and your dealer has been unable to identify the root cause after multiple visits. The fix will likely require GM to reprogram or replace the body control module and perform comprehensive electrical system diagnostics.

Your upper radiator hose and gasket may fail prematurely, causing coolant leaks. You might notice rushing fluid sounds or see coolant pooling on the driver's side where the hose connects to the radiator. A leaking radiator hose can cause your engine to overheat and fail while driving. The fix will involve replacing the faulty radiator hose and gasket.

Your Check Engine Light keeps turning on and off, and you're getting a coolant flow warning (code P30C5). Even though the coolant pump was replaced under warranty about 9 months ago, the same problem has come back, along with an "Engine and Transmission System" alert in your myChevrolet app. This issue has required multiple repair attempts since you bought the vehicle, and you're concerned about reliability for your daily 100-mile commute.

i have a 2023 Colorado and its only got 69,000 miles. my Crank shaft seal went out with no warnings. No dash lights or oil lights. ive read online where is this has happened to a few colorados. I had 0 oil on my dipstick and didn't have one check engine light on.

Transmission shifts very hard from first to second and from second to first. This occurs on the first shift of the day. I have taken the vehicle to the dealer twice and was told that, according to Chevy, this is “normal” operation.

The transmission suddenly went out while driving on the freeway. The vehicle suddenly reduced speed while on busy freeway impeding the flow of traffic.

The contact owns a 2023 Chevrolet Colorado. The contact stated while driving 35 MPH, the vehicle seemed to operate in 4WD mode; however, the instrument cluster stated that the vehicle was operating in 2WD mode. Additionally, the check engine warning light illuminated. The vehicle was taken to the dealer, where the check engine warning light was cleared. The contact also stated that while at a complete stop, the Auto START/STOP feature turned off the engine; however, upon depressing the accelerator pedal, the vehicle failed to respond, and the engine made abnormal grinding sounds. The vehicle then accelerated to 40 MPH and then slammed on the brakes unintendedly, nearly causing a crash. The contact depressed the accelerator pedal, but the vehicle failed to respond. The contact continually depressed the accelerator pedal, and the vehicle lurched forward and jerked while responding. The contact was able to pull into a parking lot. The vehicle was towed to the second dealer, Malloy Chevrolet (2700 Valley Ave, Winchester, VA 22601) where the failure recurred. The vehicle was being diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 600. The VIN was unavailable.
