Brand new 2018 midnight edition chevy Colorado less than 24hrs on the engine and had less than 900 miles on it. Went to go to work one morning and it wouldn't do anything. No revere. No power steering. All lights and gauges were flickering and going crazy. Engine was chugging and making odd noises. It would not move from my garage/driveway. Had it towed it to nearest dealership. Over 2 weeks of diagnostics it's either a steering module or a wiring harness part. Dealership tells us its faulty wiring/steering module. It is an intermittent issue and it's hard to diagnose. I really feel that this could cause many safety issues since power steering was completely out and it wanted to shut off on us. This could have been bad if it happened while we were driving it to work. The dealership we purchased it from had done some electrical work but did not disclose what was done until it quit working and was brought to a different dealership. They brought it to our attention when it was towed in. The wiring that was done before purchase is what's causing all issues electronically. Truck is currently in the shop waiting for a part that is on backorder. Waiting for paperwork after repairs are completed. If they can be completed. They're still trying to fully understand the electrical issues since it is so random. It has been in their shop for over 2 weeks now. I just want someone to be aware of these issues incase it needs to be recalled. This could be a scary issue if it happens while driving.

Tl the contact owns a 2015 Chevrolet Colorado. While driving at unknown speeds, the power steering failed and there was an abnormal buzzing noise emerging from the dashboard. In addition, the vehicle lighting spontaneously turned off and on. The vehicle was taken to the local dealer (modern Chevrolet, 800 w 4th st, winston salem, nc 27101, (336) 722-4191) where it was diagnosed that the wiring harness was chaffed. The vehicle was not repaired. The manufacturer was contacted and provided case number: 8-4441944761. The failure mileage was 63,000. The VIN was not available.

I purchased a brand new 2016 Chevrolet Colorado duromax diesel in September of 2016. At 9,638 miles the check engine light came on for the nox sensor. The dealership replaced them but it did not fix anything. As it turns out the issue was a recall which reprogrammed the ecu. They decided to make the tolerances looser on the sensors. At 10,647 miles there was a loud wining coming from the rear of the vehicle. The race to the pinion bearing in the rear differential was pitted and causing the bearing to fail. The rear differential needed to be rebuilt. At 22715 miles the truck would go into reduced power mode which is 25 miles per hour in the middle of the freeway causing other motorists to swerve to avoid a collision. When the truck was turned off and turned back on the error would clear and the vehicle was drivable again. The dealership could not replicate the issue so it took many visits before they replaced the accelerator pedal position sensor. After this did not fix the issue and almost caused another accident the vehicle was taken in and the complete wiring harness was replace. The technician stated that the connectors were improperly crimped at the factory. The truck is now at the dealership again at 26,000 miles to replace the diesel exhaust fluid pump. This fault also causes the vehicle to go into reduced power mode which almost caused an accident again. This vehicle is not reliable, dangerous, and I do not feel safe driving it, especially when my family is with me. I contacted Chevrolet customer assistance team concentrix on behalf of Chevrolet to seek a solution on a brand new vehicle that had major problems. The representative did not care and told me to pursue a resolution on my own.

Idle control via electronic throttle body raises rpm very high when the accelerator pedal is not depressed, causing uncontrolled acceleration of vehicle during coasting or when brake pedal is applied. Turning the vehicle off with the key is the only action that has resulted in a cessation of extremely high idle. After restarting the vehicle, the symptom is gone and the vehicle operates normally. This behavior is erratic and inconsistent, the problem has been difficult to duplicate during diagnosis. All testing and inspection of the electronic throttle body, wiring harness, connectors, and functions within the engine computer has shown no defect or indication that a wiring fault, dirty throttle body, or other "wear and tear" item is the cause of this intermittent revving at idle. The most recent event occurred on August 9th 2017. This has been occuring for at least 6 months, on average once a month in frequency.

Problem # 1: had to replace the hvac resistor and its wiring harness. Resistor plug and the harness plug was burned and melted. . . Fire hazard! this safety hazard could have burned up my vehicle. Problem #2: the abs warning light keeps coming on and when this happens (every day or so) the brakes do not work properly. This seems to happen when the vehicle is not parked on a level surface. The fault occurs once the vehicle moves forward from the parked position.

The contact owns a 2016 Chevrolet Colorado. While the vehicle was at the dealer, the technician diagnosed that the wiring harness had fractured. As a result, there were various electrical failures, including illumination of the air bag and traction control warning indicators. The technician stated that the wiring harness needed to be shrink wrapped. The vehicle was repaired. While the vehicle was in park or while driving at various speeds, the vehicle vibrated. The vehicle was taken back to the dealer, but was unable to be diagnosed or repaired. The manufacturer was notified of the failure and stated that a technician would be sent out to inspect the vehicle. The failure mileage was 176.

Had dent repaired on drivers fender, picked up truck from dealer, drove 4 miles home to put in garage. Next morning at 5:30 am discovered truck fire in garage due to electrical wiring harnesses. Extensive damage to garage and garage floor. Extensive damage to truck's electrical and engine area. Dealer told me it is a gm problem. Now dealing with gm legal dept. But this could be a major problem with all 2015/2016 trucks, no warning what so ever prior to incident. Vehicle is a 2015 Colorado not 1 year old with 8300 miles.

Power windows loss power, including driver and passenger windows. Wiring problem exists. Ken dixon, the dealer in waldorf, MD repaired problem on January 21, 2013 at a cost of $300 under so # 243247. But the same problem reoccurred in early Feb 2016 and the dealer refused to repair the problem without costs to the customer. The vehicle was stationary. The problem mirrors recall of the same make and model under NHTSA's campaign #14v404.

Airbag warning light stays on when engine is running. Google searched and found dozens of repeated explanations of the cause on vehicle & model years on each side of mine. The wiring from the body to the small rear extended cab door is too short and breaks as the door is used. One of the wires is in the airbag circuit and the indicator illuminates when the wire breaks. Upon looking under the rubber wire protection boot between the body & the door, it clearly revealed insufficient wire length to accommodate the door actuation. Clearly a design error and should be corrected by the manufacturer. No campaign on it per the dealer service advisor.

The blower motor resistor and the wiring is broken for the third time. This time there were burn marks on the wires which worries me about a possible fire in my dashboard. This occurs while the vehicle is on. This overheating/burning of the resistor and wires causes the blower motor to not blow air which in phoenix, az is a must due to severe hot weather.

The ac fan only works on high (4). The ac fan switch has a known defect in the resistor switch for the fan. This can cause the wiring to overheat and start a fire. Gm has already recalled the hummer h3 for the same problem. The recall should be extended to the 1st generation chevy Colorado because it has the same fan switch resistor.

Driver side back door wiring harness between door and frame. 3 wires are broken inside boot. This is second time this has happened. Lasted 3 years. I have pictures. Part number 15214393 June 10 2012 air bag light on dash. Onstar told me that seat belt tensioner was not operating, and air bag will not deploy until it is corrected. Found that driver side back door that 2 wires were broken in the harness in the between door and body in boot. Gm part number 15214393. I have pictures. This is a problem and still no recall. No air bags till fixed.

Airbag light is on. My truck has never been in an accident. Through research I have found that the wiring in the door breaks.

The contact owns a 2011 Chevrolet Colorado. While driving, the air bag indicator remained illuminated. The failure recurred twice. The vehicle was taken to the dealer where the driver side rear door wiring harness was repaired. The vehicle was taken to the dealer a second time and the wiring harness was replaced; however, the failure recurred. The manufacturer was notified of the failure. The failure mileage was 47,270.

The wiring harness between the truck body and the rear driver side half-door (extended cab) passes through a flexible rubber housing. The pair of wires to the seat belt tensioner (part of the airbag system) were broken completely in half mid-way through the rubber housing from normal use of opening and closing the door. Airbag light on dash stayed on permanently which prompted me to locate the problem. Only found it because the radio speaker in that same door had stopped working as well. Found that it had broken wires in the same location along with the airbag system wires. This problem is well documented in online forums as many Colorado owners across many production years have had the same issue.

I own a 2006 chevy Colorado extended cab. The air bag readiness light stayed on after starting the vehicle. According to the manual, if the air bag readiness light stays on after you start the vehicle, it means the airbag is not in working order. The airbags may not inflate in a crash or they could inflate without a crash. This is a safety problem. I am concerned that the airbag would not deploy if involved in a crash. I am also concerned about having the air bag deploy under normal driving. There is a wiring harness that travels through the hinge of the rear door that appears to be a problem. The opening and closing of the rear doors has caused the wires to break. This rear door gets opened maybe 1 out of every 10 times the vehicle is entered/exited. Since the problem involves the airbags I thought it would be best to take it to the dealership for them to repair. Since there has not been an recall issued, I have had to pay for this myself.

2012 Chevrolet Colorado. Consumer writes in regards to transmission issues. The consumer stated the vehicle would not start. The vehicle was towed to the dealer. When the consumer called the dealer a couple of days later, he was informed the issue was the transmission. The next week, the consumer was informed, the parts replaced in the transmission were not issue, and after further investigation, the issue was a loose timing chain tensioner. Later in the week, he was informed that the engine was damaged and there may have been a spun bearing that caused the issues. The consumer was then informed the engine needed to replaced, but it would take couple of days to get an approval for the replacement. The authorization finally came through and the dealer proceeded to replace the engine the following week. The consumer was told he could pick the vehicle up on June 1st. However, they wanted to put some additional miles on the truck to confirm everything was in specification. When the consumer arrived at the dealer, he was informed the vehicle overheated and had to be towed back to the dealership. The dealer had the vehicle for two weeks. The consumer stated the vehicle continued to have problems. He stated the truck would idle in a rough manner , and the check engine light illuminated. The consumer stated he checked the codes on the vehicle, and determined they were transmission related. The consumer went to another dealer, who diagnosed the problem as a wiring harness issue and some crimped seals from the first dealerships workmanship. The vehicle was properly repaired and returned to the consumer.

Wiring for turnsignals melts down. There is a wire harness with a connector at the turn front signals, the wire gauge is in adeqaute and causea excessive heat build-up this causes the wires and connectors to the front turn signals to melt down and the turn signals become inoperable. I have replaced these components twice due to thia issue. The resistor pack for air conditioning blower fan speed control melts and catches fire. I have replaced this part twice and ultimately have bypassed the resistor pack leaving the ac blower with only the choice of high speed or off.

Heater fan does not work. It is wintertime and I have two children ages 4 1/2 years and 9 months. Faulty wiring for the fan.

The contact owns a 2005 Chevrolet Colorado. The contact stated that the air bag warning light remained illuminated. The vehicle was taken to the dealer who diagnose that the extended cab driver side rear door wiring harness that included the radio speaker, seat belt, and air bag wires was broken. The vehicle was repaired. The failure mileage was 79,300 and the current mileage was 79,400.

The vehicle fan control fails to function on settings 1, 2, or 3. Setting 4 functions properly. The connector plug at the fan housing and wiring harness shows signs of charring.

2005 chevy Colorado wiring harness on fan control burnt up at motor plug. Wires in harness started smoking and melted plastic. Harness and resistor had to be replaced.

Blower motor on my 2006 Chevrolet Colorado quit working except for the high position. Leaving the fan in the high position too long will cause the fan to quit working and then there is no a/c , heater or defogger that will work when needed. I took it to the dealer who told me that he knows what the problem may be, a relay or the wiring harness. At a cost of 328. 00. He told me off the record if I wiggle the wiring harness it may work for a while since the harness most likely was incorrectly routed. . I have talked to many Colorado and GMC canyon owners both in person and on internet forums who reported that they are having the same exact problem. This issue could be a safety issue especially in the winter time when the defogger is really needed to keep the windows clear for safe driving. I iknitially thought that it was just a simple burned out motor , and I would just need to replace it. But since what I was told from the dealer service writer, and what others have said in the forums, I would be wasting money especially is it is from a bad wiring harness. I think gm should look into this and make needed repairs.

2007 Chevrolet Colorado. Consumer states vehicle caught fire while parked according to the fire report, the fire was caused by a faulty wire in the driver's heated seat.

The cooling/heating blower fan speed resistor and wiring harness on the 2004-2009 chevy Colorado has a shorting problem which causes the truck to have a smoke smell and may lead to a fire if not checked on. I found mine after smelling smoke for a few months and started checking where it was coming from. I found the fan speed resistor connector and associated wiring harness burnt and slightly melted. I would have taken to the dealer but it was out of warranty and did not want to pay there high labor costs. This is the second time changing this out in the last year and I found that there is a common grounding point on the passenger side fender wall which over time becomes corroded and makes a bad ground most likely causing the shorting problem. If this is not worthy of a recall then I would like to at least have a warning notice sent to owners so they would know what to look for if this happens to them.

The blower module wire harness continually goes out. I have replaced it twice and the same thing happens. Appears to me that there is some sort of short in the wiring. If you take off the bad harness and look down in the connectors one of them is always burnt up. I worry that it could cause a potential fire hazard. I know that I am not the only person that is happening to. I continually check internet blogs and it seems to happen more often than not.

2005 Chevrolet Colorado 5 cylinder 4 wheel drive automatic 68,000 mi engine misfire 7 times taken to garage $1,300 paid and no one could fix problem. Finally took vehicle to dealer who charged $325 to change spark plugs and then admitted that there was a problem with this engine. Intake valve seals are defective. Now vehicle needs a $500 repair of front transaxle seal. All electrical connectors on this vehicle are of inferior quality, I have experienced 3 failures of stoplamp wiring,4 failures of signal light wiring, and 2 failures of a/c blower motor, all due to poor electrical connectors. My concern is that in case of an accident the air bags would not deploy because of a similar problem. This is a potential safety issue, and should be evaluated.

Blower motor fan speeds work intermittently. Fault was found in blower motor wiring harness where harness runs adjacent to glove box. Jostle the harness manually below the glove box and the blower motor speeds will go from off to only a few speeds to normal. This could definitely be a fire hazard.

Went to turn on the cabin fan on speeds 1-3 and the fan would not turn on. Speed 4 (the fan has 4 speeds), the fan would come on. After giving the truck time to warm up, sometimes the fan would then turn run on the lower speeds. This happened a many times during the summer. Sometimes, even given 20 minutes of running the vehicle, the fan would not run on lower speeds. After a month or so without doing anything, the fan worked as expected. Lately the problem started to reappear, again, the fan would only run on high. Just like before, even given 20 minutes of run time, the fan would not run on lower speeds. The fix was two fold. The root cause of the issue was a bad grounding block, that then would cause a short in a wiring harness. The grounding connection for the fan, was secured. Second the wiring harness for the fan control along with a resistor had to be replaced. . Read more...

The dashboard lights will stop working if your driving at night and turn the car off and then turn it back on. They will not work until the car sits for a long period of time. This started soon after buying the car brand new, but the dealership couldn't find anything wrong. Second complaint, the heater/air conditioner fan had an electrical fire at where the harness plugs into the fan motor. The fan will only work on high. When I looked online at other complaints about the same problem, I unplugged the fan and noticed the plug was burnt. I have photos that I can send. It appeared the electrical fire continued down the plastic plug to where the wires are exposed. This could have been a major incident if I didn't notice it. There are a lot of complaints about this with Colorado trucks online. Also when driving at night, my dash lights and instrument lights flicker as if there is another electrical short somewhere in the wiring harness.

The contact owns a 2007 Chevrolet Colorado. While driving 30 mph, the vehicle lost acceleration, began smoking, and finally stalled. The dealer only offered a warranty on the parts and made three attempts to repair the vehicle within the last three months. The dealer is not repairing the failure by replacing the wiring that melted and burned. The repair receipt states that the cause of the failure was an electric continuity through negative cable. The parts were replaced under warranty. The current mileage was 39,000 miles and failure mileage was 31,000.

Blower fan works intermittently. Finally stopped working on settings 1,2 and 3, will only work on setting 4. Replaced resister 1st from dealer, the climate switch panel. Finally the fan wouldn't run @ all, took to local mechanic replaced wiring harness & fan motor. Took about a year to get truck fully repaired.

The contact owns a 2007 Chevrolet Colorado. While driving 70 mph with the cruise control activated, the engine shut off completely. The dealer could not find any failure. A week later, the vehicle lost power again and was returned to the dealer. The dealer placed a recorder in the vehicle. The vehicle lost power twice afterwards and the recorder was able to receive two snapshots of the system. The dealers then acknowledged the failure. From the data that was received, the vehicle then began to shut off while the cruise control was deactivated with the engine running. The contact notified the state attorney general's office to file a lemon law claim. He was advised to call NHTSA. Presently, the vehicle has been at the dealer for over two weeks. The failure mileage was 6,796 and current mileage was 12,647. Updated.

The chevy Colorado extended cab model has a history of the wire breaking in the same location causing the air bag (srs) light to remain on. I believe this manufacturing defect may not activate the srs in the event of a side impact. The wire in question is located inside a rubber boot between the rear doors and the main cab body. It seems if you use the rear doors it will develop a broken wire.
