2016 Chevrolet Colorado Engine Problems

Vacuum pump busted as shown in photos. Once that busted it sent metal shrapnel into the engine which broke a piece of the cam shaft into bits. There were metal fragments that had to be meticulously cleaned out of my engine block. The loss of vacuum seal caused me to lose brakes while driving in stop and go traffic on the highway.

COMPONENT: The piston in cylinder #1 cracked and created conditions for the fuel injector to bore a hole through it. SAFETY: This led to sudden loss of engine power and violent shaking of the vehicle at highway speeds. CONFIRMATION: Multiple reports of the exact same incident can be confirmed and researched at ColoradoFans.com, specifically on these threads https://www.coloradofans.com/threads/looks-like-my-number-finally-came-up-engine-failure.444376 https://www.coloradofans.com/threads/poll-how-many-blown-up-2-8-diesels-please-indicate-on-poll.396705/ https://www.coloradofans.com/threads/documented-2-8l-duramax-lwn-engine-catastrophic-failures-thread.427244 INSPECTION: Confirmed the crack and the hole in piston #1 with borescope. WARNINGS: Prior to catastrophic failure, there was an ongoing intermittent issue chasing down DTC P11CC - NOx1 Performance Low. Not sure if that was a harbinger or completely unrelated.

While making a left turn through an intersection, the vehicle's engine shut down without any warning. The electronics were still powered. My safety was put at risk, as other drivers were also going through the intersection. If this issue occurs again at another random time and I lose power while driving, this could easily result in an accident. I have not had it inspected by a mechanic, since it just happened, but have read online that others with Chevy Colorados have had this issue and could not find the cause.

The contact owns a 2016 Chevrolet Colorado. The contact stated while driving 45 MPH, upon reaching the top of an incline, the vehicle began to shudder before losing motive power. The contact pushed the vehicle to the shoulder of the roadway, where the vehicle failed to restart. The check warning light was illuminated. The vehicle was towed to the dealer, who diagnosed failures with the purge valve and mass air flow sensor. The vehicle was repaired, but the failure reoccurred. The dealer was made aware of the failure and informed the contact that there was a possible failure with the vent valve canister. After a visual inspection of the engine compartment, the contact discovered water within the vent valve canister. After investigating the failure, the contact related it to Emission Recall: N202313200. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was 96,000.

I have asthma and it is controlled by medication when needed. Recently I have had a lot more incidents of breathing difficulty since I purchased my vehicle. It was during one of these episodes that my wife noticed an odor associated with antifreeze. However, there is no moisture in the vehicle and no visible leaks or puddles on the ground. I have detected the same odor when standing near the back of the truck near the tailpipe. Also, I have had to refill the radiator with exactly five gallons of Antifreeze in less than 3000 miles of driving. It was my wife who alerted me to the odor being inside the vehicle and only during times when the heater was running. Since that time I have driven the vehicle only when I can safely leave the heater off, because I cannot be sure it is safe. If I need the heater to defrost, I leave the vehicle. Also, I noticed that when the engine coolant is low, the engine never seems to overheat, and the heater no longer blows hot air. Is this an issue involving only my vehicles and what other health risks are there? The most I have had to add to restore heat is a gallon of coolant.

One morning I started my truck to go to work and the engine started ticking when I arrived at work the engine was still ticking . Being a European Automotive Technician for 34 years I knew this was bad . I performed an extensive diagnosis of the engine and found metal particles in the oil and filter at that point I knew that something in the engine had failed . I removed the engine and removed the oil pan for further inspection and discovered that the # 2 cylinder piston was broken below the wrist pin.

THE TRUCK WILL RANDOMLY SHUT OFF WHILE DRIVING, SITTING STILL, AND THEN START BACK UP WITH NO PROBLEM. THE TRUCK ISN'T REPORTING ANY CODES BUT THE ENGINE HAS RANDOMLY CUT OFF DURING OPERATION ON SEVERAL OCCASIONS. I HAVE READ MANY FORUMS OF OTHERS HAVING THIS ISSUE. THIS HAS HAPPENED TO ME WHILE PULLING OUT INTO TRAFFIC ON A CITY STREET AND ALMOST CAUSING A MAJOR ACCIDENT. IT OCCURRED AT SEVERAL TRAFFIC LIGHTS AND ALSO MERGING ONTO A HIGHWAY EXIT. THIS IS A MAJOR PROBLEM WITH SERIOUS RISKS INVOLVED!

COMING OFF STEEP HILL AND TRANSMISSION DOWNSHIFTED TO LOW GEAR, THE ENGINE REVVED UP AND WOULD NOT SHIFT OUT. TRIED GIVING AND LETTING OFF GAS, FINALLY PUT IT IN NEUTRAL TO LET RPM'S GO DOWN AND PUT BACK IN DRIVE AND IT FINALLY SHIFTED ON OUT. TOOK TO DEALERSHIP WHERE I PURCHASED AND THEY TEST DROVE IT AND SAID THE HILL DESCENT FUNCTION WAS NOT WORKING PROPERLY BUT THERE WERE NO RECALLS OR SOFTWARE UPDATE ISSUE AT THIS TIME THAT WAS COVERED UNDER WARRANTY. ISSUED COMPLAINT TO CHEVROLET AND THEY SAID THERE WERE NOT ENOUGH COMPLAINTS TO ADDRESS THIS ISSUE AT THIS TIME. VERY FRUSTRATED.

I HAVE A 2016 CHEVY COLORADO 4 CYLINDER TRUCK AT THE DEALER AGAIN. HAD IT IN ABOUT 8-10 MONTHS AGO ON THE ENGINE REVIVING REAL HIGH WHEN COMING TO A STOP. THEY SAID IT WAS PROBABLY THE HILL ASSIST SYSTEM AND NOTHING THEY COULD DO. NOW IT'S CHRONIC. IT CAN REV TO 2200 RPMS AS I COME TO A STOP. I HAVE TO KICK IT IN NEUTRAL TO KEEP FROM HITTING A KID IN A CROSSWALK OR THE CAR IN FRONT OF THE. BOTH FEET ON THE BRAKES. AND, WHEN I PUT IT IN NEUTRAL, IT CAN REV UP TO 4000 RPM'S. IT'S BACK AT THE DEALER NOW AND THEY DON'T HAVE ANY SERVICE BULLETINS ON IT. I TEST DROVE A V-6 300 HP MODEL WHILE THERE AND IT DID THE SAME THING 2 TIMES AND THE SALESMAN DIDN'T NOTICE, BUT IT NEVER GOT OVER 1800 RPMS. SO,THEY HAVEN'T FIXED IT. BUT THEY'RE SINCERELY TRIED BUT I THINK IT'S THE SYSTEM NOT THE DEALER. THE HILL ASSIST SYSTEM DOESN'T PICK UP ON IF YOU'RE LEVEL OR GOING DOWN A HILL ANYMORE. JUST REVS UP, AND IT'S IN 1ST GEAR WHEN COMING TO A STOP.THE TORQUE IS TREMENDOUS ON THE BRAKES. IT'S AN ACCIDENT WAITING TO HAPPEN. I DON'T THINK THE DEALER IS NEGLIGENT IN ANYWAY, I THINK IT'S THE COMPUTER DESIGN ON THAT HILL ASSIST HAS GONE HAYWIRE ON US. *TR
