The key does not release when in park! I have to adjust the steering wheel and gear shift multiple times to get it to release. This has been going on for a while and the truck only has 27,000 miles. I've called multiple chevy dealers (including the one I bought it from) they all want a 250 diagnostic fee! This should be under warranty. This problem is dangerous. I have seen I am not the only one having this issue. This issue needs to be investigated and recalled!
Complete engine failure due to defective crankshaft malfunction, truck taken to certified repair shop and then dealer, deal not responding for 24 days. Engine failed traveling on the highway was fortunately able to pull over, stranded. Engine light came on and the engine failed completely 5-10 min after on a 2 hour return trip home. Certified repair shop informed me this is the exact same reason of the recall just that my vehicle wasn’t currently under the recall. Vehicle component has been recalled on other Chevrolet vehicles manufactured during the same time just not this one yet.
There was a catastrophic engine failure of a 2021 Colorado 3.6L V6 engine. The engine has been replaced by GM and the failed engine is in the dealers' possession. While driving on a congested street, the engine misfired and immediately stopped. The vehicle rolled to a stop in the middle of 3 lanes. Occupants had to flag down traffic while pushing vehicle to the side. There was no warning lamps, messages or other symptoms, such as knocking, prior to the failure; and the oil service was maintained per manufacturer. Two separate dealers found "piston to valve contact, top of piston severely damaged, and metalic debris in intake plenum." GM Service Bulletin 19-NA-256 has identified "Seized engine" caused by defective "crankshaft main or rod bearing failure" that can put the oil filter "in by-pass and distribute unfiltered oil with bearing debris throughout the engine." In addition to the rod bearings, designated inspection points are the cam caps and camshaft journals on the heads and the timing change idler sprocket for stiffness when turning. Since the vehicle was 15,000 miles over the 60K warranty, they would not perform the designated diagnostic steps in Service Bulletin. Owner waiting on independent oil analysis. Service department provided pictures of metallic debris and valve damage, as well as the damaged spark plug. After opening Case # 9-14977425869 with GM Customer Service and asking why Warranty has not been extended or a Recall issued for the known manufacturer defect in the TSB, the response was "it likely has not occurred enough times to warrant a recall". With a dealer discount, total towing, diagnostic and repair costs exceed $11,000. Results of Blackstone Labs oil analysis will be provided when completed, however, the oil was just changed 462 miles prior to the failure, so a sample of the previous oil that would have contributed the most to the failure was not available (6,948 mi on previous oil).
The contact owns a 2021 Chevrolet Colorado. The contact stated that while driving at unknown speeds, the check engine warning light illuminated. Additionally, the navigational system and radio continued to reboot, and volume increased to high levels without driver interaction. The contact replaced bank two and valve two and stated that the cam shaft exhaust was faulty. The vehicle was repaired, but the failure recurred. The vehicle was taken to an independent mechanic, who informed the contact that the failure was due to bank two, the cam shaft, and that the vehicle was idling roughly. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the local dealer. The failure mileage was approximately 46,000.
The engine is needing replaced. I was driving down [XXX] and the engine, electric control system, and stability lights all went off. The engine started shaking. The Chevrolet dealership says it's $6,500 before tax to diagnose or I can replace it for $10k before tax. I believe they know what the issue is, but not telling. The engine should not fail so.soon.

The brakes went out on the vehicle while my service technician was driving and he barely missed getting in an accident. We had it towed to the Chevy dealer and the brake Pump shattered causing damage to the exhaust clamp and they are telling me it’s not under warranty or recall but I see this is happened with millions of other Chevy vehicles?
Just prior to 8/1/22, check engine light came on. They found P0014 set, lack of power, rough idle. They found oil pushed through bank 1 cam solenoid actuator and had to replace on 8/1/22. Check engine light came on again in mid August 2023. Found P0024 code and had had to replace the cam actuator again. This time GM has part on backorder, like they are fixing systemic issue with part. They could only replace by getting from another dealer. Still charged me for part even though it was just replaced 12months ago. Would like to know if this is a systemic issue with GM.
I have 2021 Chevy Colorado pickup truck. Put the truck in park and unable to turn off and remove the key. This is the third time this has happened this week . The first two times I moved the shifter from park to drive and back and it released. The last time I had to sit in my drive way for twenty minutes with the truck running before I could turn the key to shut off the truck. This is a very dangerous situation if there was every an emergency and not being able the shut off the truck.
Gear shifter won't recognize the truck is in park. When attempting to turn off vehicle accessories stay on and key will not come out. Dealer replaced my shifter today and the third time parking after being fixed, the issue remains.
