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.

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.

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.

my truck has a issue when you are going down a hill it shifts into a lower gear. This is an automatic transmission. This can cause my truck to slide and spin in bad weather.

2016-2020 Chevy Colorado and GMC Canyon diesel models have faulty DPF and DEF systems that fail within <20-60K miles. They do not warranty it as powertrain, and it is a common problem. SAFETY ISSUE: While out of state, the vehicle regenerating exhaust cleaning cycle can not properly clean the system. It then goes into limp mode. 2 dealers have tried to fix it, with no avail. Limp mode limits speed from 65mph with no power on hills, to 55, then 4mph. See this thread for how many people are experiencing problems: https://www.coloradodiesel.org/threads/dpf-regeneration.1137/page-2 Thank you, Andrew R

During any type of moisture ie (fog, rain) vehicle goes into reduced engine power mode codes from the ECM P2122 and P2138 both relating to app. First time it happened was in rain storm in motion, app pedal was replaced with new oem part but the problem persists. I suspect water intrusion from wiper cowling affecting electric harness. This problem does not exist during dry season. After many hours of online research I have found that this is a widespread problem in Chevrolet vehicles.

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!

The check engine light came on it popped up engine power reduced wouldn't go over 35 miles and hr on the interstate is not a good thing. I pulled over turned car off. Turned key back on started it was fine. A couple weeks later pulling out in traffic check engine.light.comes on and loses power again almost get hit. Go to parts.store to plug machine for diagnosis. First it said unknown. So we do it again PA201 00 code. Computer said CO2 sensor. I was told a tsb bulletin came in for this software update but nobody wants to talk about it they just want to fix it then charge.U for it.but.I think it should be covered software issues shouldn't be absorbed at customers exspense. My truck is a turbo diesel its hard to find parts for it at part store and diagnostic machine just getting in oil filters. Anyway in response of software it should be covered by someone else besides me. Before it loses power and vet's me killed or I. a wreck need issue resolved

I was turning through a busy intersection and as I completed my turn and came to a stop the engine shut down. Prior to making the turn the engine felt like it was going to stall out and quit running. I have experienced the sluggish idle before but it never shut down like it did today. A google search revealed that Chevrolet has a technical sb, 16-na-284 that says a reprogram of the computer is required to correct the problem. In my opinion this is a safety issue. I was fortunate to have completed my turn before it quit running but someone else may not even be aware of the situation putting themselves at risk if it would happen to quit during the turn with oncoming traffic.
