2021 CHEVROLET COLORADO

ENGINE

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!

I own a 2021 Chevrolet Colorado Lt Extended Cab 2WD. The rear differential has failed prematurely at 70000 miles. the failure caused loud whining/grinding noises, vibration, and unsafe driving conditions. After researching online, i found many other 2021 Colorado owners reporting the same issue with rear differential failure, often at relatively low mileage. This indicates a widespread defect in the differential assembly. There are existing GM Technical Service Bulletins (20-NA-034, 20-NA-156) related to axle/differential noise and machining defects, but GM has not issued a recall or extended warranty coverage. Differential failure can lead to loss of power to the wheels or lockup while driving, which poses a serious safety risk. I request that NHTSA investigate this issue and require GM to issue a recall or Special coverage adjustment for the affected vehicles.

UNKNOWN OR OTHER

Backup camera has failed at 38,000 miles. Backed into a tree damaging the rear bumper.

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.

The contact owns a 2021 Chevrolet Colorado. The contact stated that while driving 45 MPH, the vehicle lost automotive power. No warning light was illuminated. The contact pulled over to the shoulder and the started and fuel pump fuse were replaced as a temporary repair. The vehicle was towed to a local dealer, where it was diagnosed and determined that the starter and fuel pump fuse needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the same local dealer; however, after the second attempt to repair the vehicle, the failure persisted. The vehicle was taken to Stingray Chevrolet (2002 N Frontage Rd, Plant City, FL 33563); where the vehicle was purchased, and the contact requested a second opinion. The contact stated that the vehicle was repaired; however, the failure reoccurred. The manufacturer was made aware of the failure. The failure mileage was approximately 27,000.

ENGINE

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).

SERVICE BRAKES

The vacuum pump brake booster on my Chevy Colorado went out with no warning first the camshaft went out then once the cam shaft was fixed the brakes didnt work luckily I made it home but the risk was there as the brakes became incredibly stiff and hard to press with me using all my weight to stop the truck I had a mechanic look at it and confirm the pump/booster as the readings show it’s getting power and that it has air but the pump is not working there was no warning no lights no nothing one day it was working the next it wasn’t same with the camshaft both things happened with zero warning

SERVICE BRAKES

Brakes make an intermittent grinding sound when cold but make no abnormal sounds when it is warm out. As far as the suspension goes..... The truck sits higher on the passenger side than the driver side by almost 1 inch.

When truck is put into park the key will not turn to the unlocked position, the key only goes as far as the accessories position. Not sure that the truck actually goes into park since I can not remove the key without playing with the shifter. This is a continuous problem with the truck
