1 Alternator/generator/regulator problem of the 2017 Chevrolet Colorado

Failure Date: 07/11/2020

I test drove the vehicle at or around 12 noon on 6july 2020 for the 15 maximum time allowed to test drive. The vehicle was delivered at 10 pm. . . The next morning I noticed the service theft deterrent system light was on and it would not turn off. After researching it was determined the dealership did not issue me a master fob and this could have caused the vehicle to shut down at any time (which it did 3 times in a 5 day period) . The very next day I was driving the vehicle and the vehicle stalled in traffic on the highway and just stopped. The stalling and vehicle cutting off in traffic happened 2 additional times in 5 days before I contacted the dealer. . . I thought maybe it was the battery because of lack of power in the vehicle but I was informed after a battery test it was the alternator . . . The alternator had an output of about 15. 8 which I was informed is a dangerous level the truck could catch on fire is not fixed. I contacted the dealer the night of the 10th and called on 11 July 2020 and spoke to service manager samantha she informed me she had passed the email to her manager. I did not receive a response via email or telephone. After a second email and call ricardo the salesman text me to inform me my key would be in the mail at my house on Monday the 13th which it was however I have to pay the dealer to get it programmed. The vehicle was sold as is (which I have no issue with) therefore my complaint is the dealer is selling vehicles that are dangerous and they had to know the vehicle had alternator issues and didn't fix it. Instead sold it as is risking the lives of anyone is the vehicle or around it. Ricardo text me as if I was complaining about $200 I paid $18000 cash $200 is my last concern however I am concerned about my life and those around me.

3 Alternator/generator/regulator problem of the 2017 Chevrolet Colorado

Failure Date: 11/18/2017

I own a 2017 chevy Colorado z71 4x4. Once back on the highway after off-roading on the beach, while forward driving at roughly 50 mph I ran over a chopped piece of fire wood in the road. The piece of wood contacted the skid plate, which then collapsed the hollow skid plate bracket welded to the front cross section/axle of the chassis, which then flattened into the plastic power steering module(s) connected to the electric power steering (eps) rack. This caused immediate loss of power steering, loss of abs vehicle control, loss of electrical charge from the alternator to the battery, loss of ability of the vehicle to show correct speed, random transmission shifting (into and out of gears, as well as throwing vehicle into neutral) as well as intermittent loss of all cabin electronics (including tachometer relaying speed and rpms, odometer, fuel gauge, battery voltage gauge, etc. ). Due to this being a road hazard incident, as well as poor manufacturer design/placement of a plastic electric power steering rack, I was forced to have the vehicle towed and file a claim with my insurance company. Repairs have been ongoing for 3 weeks and are still incomplete as the vehicle's computer cannot recognize the new oem part. Attached photos show damage with the skid plate removed. Mathematical measurements will prove the collapsible bracket, if flattened in a similar directional manner, will most definitely make contact with and impact the electric power steering rack. This plastic rack also includes other modules that impact the aforementioned performance issues. Gm has failed to acknowledge my concern of design after multiple attempts and conact with their.

5 Alternator/generator/regulator problem of the 2005 Chevrolet Colorado

Failure Date: 04/14/2012

On Saturday morning my truck would not start. I went to jump it, and with no keys in the ignition and not jumped yet the windshield wipers and interior light went on. This went on for over an hour. I replaced basically a new battery. The radio did not work and dash lights did not either. On Tuesday, April 17 after I picked up my son from school, the car started to make a loud scrunch noise and started to stall off and on. When I pulled into my drive way and shut off the engine I smelled something burning. I went to open the door and it would not open. I tried to open the windows and they would not go down. It was smelling really bad like something was on fire. About 25 seconds later, with no key in the ignition the interior lights went on. I put the key in the ignition but did not start it and tried the windows again and my drivers side went down and I got my son out through the window. It had to be towed to the dealership. They said it was my alternator which is getting fixed. Reading all the complaints I agree, why has this not been recalled. It's around 50k miles and the electrical goes. Luckily me and my son got out.

Could cause fire!!! ac speed regulator of my 2004 crew-cab Colorado overheated so much that the adapter burnt in the inside and cables overheated to the point that it couldn't be touched and started to smoke. This is located underneath the glovebox compartment. If this is left unattended could cause a fire inside the vehicle!.

7 Alternator/generator/regulator problem of the 2004 Chevrolet Colorado

Failure Date: 06/11/2009

Throughout the course of ownership, I've had several complaints to the dealership concerning the faulty electrical wiring in my vehicle. Since 2004, all repairs have been electrical problems. I have reason to believe that the faulty wiring in my vehicle was the cause of fire to my vehicle which resulted in a total loss. I was also made aware by local firemen at the scene that they've had the same type of fires with the same make and model vehicle just in my area alone. Here is a summary of service history since taking ownership in 2004: brake switch replacement: 11/19/2004, 1/23/2006, 1/26/2007, and 5/26/2008 r&r blower resistor replacement: 8/28/2007 rear window regulator replacement: 5/1/2006 speaker replacement: 5/1/2006 complained about various electrical wiring issues on 1-24-05, 9-1-05, and 1-26-07 .
