While driving my 2020 Chevrolet Colorado through [XXX], the truck began having difficulty accelerating. As I exited the highway and turned into a gas station, the truck suddenly lost power. The steering became extremely difficult, and I lost normal brake assist. The brake pedal became extremely hard, and I had to apply extreme force to stop the truck and avoid crashing into a wall at the gas station. Fortunately, no collision occurred. The truck was towed to Ed Corley Ford in [XXX] because I was stranded in a remote area with very limited options. They diagnosed a failed/broken vacuum pump and told me replacing it should make the truck operable so I could drive it home to [XXX]. I authorized the repair. After replacing the vacuum pump, they told me they started the truck and heard an abnormal sound. They shut it off, and when they tried to restart it, the truck would not start. They wanted to perform additional diagnosis, but I declined and had the truck transported back to [XXX] for evaluation by a Chevrolet dealership. Huffines Chevrolet Lewisville inspected the truck. Their technician removed the camshaft position sensor and used a borescope to inspect the camshaft. They documented that the camshaft is damaged at the end where it connects to the vacuum pump and stated the actuator pin was most likely bent due to the vacuum-pump failure, damaging the camshaft and causing it to be slightly out of time. I have also been informed of engine damage. The truck remains inoperable and is currently available for inspection. I am concerned this is a safety defect because the vacuum-pump failure resulted in a sudden loss of normal brake assist while I was driving and was followed by camshaft/engine damage. I am asking the federal safety agency to investigate this failure and similar Chevrolet Colorado complaints.

Highlighting a materials defect with the rear crankshaft reluctor ring on the 2.8 LWN Duramax, installed in the Army Infantry Squad Vehicle and the 2015-2023 Chevrolet Colorado, from which it is based. When the ring delaminates, due to age, the vehicle engine shuts off and no start, rendered dead lined, as the ECU can no longer "see" the crank position. Requiring the transmission to be removed to rectify the issue.  I was pulling a trailer up a hill on the freeway when my truck down shifted, in an effort to slow down for a bus that was merging unexpectedly and the truck died at speed. The increase in RPM initiated an unplanned, instant disassembly of the ring due to cracking on the material and increased centrifugal force, shutting off the engine without warning, at speed. Again, just dead stick to the shoulder, towing a trailer, on the freeway. That could have been bad... Had truck towed to GM dealer, for a month-long repair.

Pass lock. Sometimes vehicle doesn't start

Filed Nov 15, 2024 · Electrical, Engine · CA

07-01-23 Vehicle died out, wouldn't start, got jumped, still wouldn't start. No indicator lights or warnings. Towed vehicle to the dealership, where it was for 11 1/2 months with the determination it was the ECM and Harness. Which it took that long to get. The vehicle was given back 06-14-24, even though it was in running condition, it was discovered parts were missing. Dealership put on order, received by end of July and installed. November 13, 2024, vehicle died out while driving on the freeway. Dashboard lit up everything, had to get the vehicle towed back to dealership. I have the Onstar diagnostics indicating the same components as the original reason the vehicle was held for an approximate year. Dealership now has vehicle and we have to wait for them to do a diagnostic.

I was driving to lunch and without warning, my brakes failed when I approached a 4-way stop. With ABS, I was able to stop my vehicle safely in a parking lot. However, the when I turned the vehicle off, it would not start again. The vacuum pump seized and since it is driven by the exhaust camshaft, it destroyed the exhaust camshaft. It's been two weeks and I have been unable to acquire that part. I have been notified by GM parts distributors that the part is on a national supply delay with no firm ETA from GM. It seems to be a very common failure. I have been out of a vehicle for over two weeks because of this failure. I also could have been in a terrible accident since the vacuum pump failed without warning. I have checked chevy forums and several others reported the same issue.

3 different issues 1. Automatic emergency braking: Was driving and truck slammed brakes twice at 55 mph to 15mph There was no cars or people anywhere around truck when it happened. The jolt was so bad my neck and my wrist hurt for 3 to 4 days, If there was it would have caused an accident. Took truck in twice once to for recall and 2nd for the brakes slamming. Chevy said they couldnt make it happen again so they cant fix it. I explained it didnt happen for over 11,000 miles so how I just have to wait until it happens again. The light and sound still goes off randomly but brakes haven't slammed yet. Very dangerous this really puts mine and others at risk. 2. Windows don't always go down Part has been on order may still waiting Aug 11, 2024 3. Recently truck won't start battery dead. Going to take in tomorrow. I reached out to gm due to chevy dealer said they are the only ones that can fix issue. That didn't work either. I still have a brand new deg Effective truck. Don't know what else to do. Lawyer says to take it in 2 more times then they can start a case. All I want is it fixed specially when I bought it new.

The vehicle has an electronic issue where it does not recognize the original key to the car. It does not let you start the vehicle. There is a bad sensor in the ignition lock housing unit located where the key is inserted into the vehicle. This issue will nit let the driver start the car and the problem happens at random. For me it is 1 out of 20 times i try to start my vehicle it does not start due to this issue. This is a dangerous situation for me, as I live in a cold weather state in the US. I have been left stranded dozens of times because the car doesn’t recognize the key. If you search “chevy colorado passlock” hundreds of videos will come up, each video with thousands of views (from users like myself). GM charges hundreds to fix the issue. It is a well known issue with this vehicle. I fixed the issue myself. I replaced the faulty sensor and the issue is gone.

Ignition safety module known as pass lock security. This causes my vehicle not to start and give a code and a light on the dash for the Pass Lock security. The vehicle was fine then I went into a store came out and put the key in the ignition, the lights on the dash came on but it would not crank. This is very hazardous cause It could happen while you’re driving anytime, which could cause the vehicle to go into security mode and turn vehicle off making it very dangerous for passengers in vehicle. This is a problem with other Chevy Colorado's when I research this problem.
