Filed Feb 5, 2019 · Body, Brakes · MA

Truck has 25,000 miles. I do not drive it often because fuel economy has never been as advertised, no better than 15 mpg. When it worked, it was fun to drive. Now fails inspection because the frame is severely rusted, my truck is now unsafe. Not cost effective to repair, I have to sell as scrap. Radio replaced once. Blower works but very noisy. Abs sensors were replaced after 10,000 miles and need replacement again. I have replaced inner and outer tie rods after 21k miles. I have replaced gas tank gasket and exterior cab brake light. Also replaced transmission shifter cable due to rust. Tube on rack and pinion rusted and replaced. Tiny coolant leak that I cant find. All I can remember. Most faulty vehicle I have ever owned. Never buy a first year model of any vehicle.

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.

Everyday now when I try to start the truck it turns over but will not start, wait 15 minutes then it will start. Today when I tried it the first time it turned over but would not start so when I turned it off at the key it stopped then tried to start again on its own for about 8 to 10 secs. The starter turned the engine over without touching the ignition switch it then stopped for about 3 or 4 secs then tried to start on its own again without touching the key, it did this start sequence 3 times in a row. The gm passlock system is terribly defective as reported by all the reports online and I believe my problems are a result of this system.

I recently took my chevrolet colorado in to a chevrolet dealership because my "check engine" light was on. It was diagnosed that a sensor on the gas tank was rusted and needed to be replaced. The service manager admitted this was common for a colorado. Parts were ordered and I was told it would cost about $800 to fix. I brought my truck in a few days later to have the work done. Later that day I was called and asked to come in because they found another problem with my truck that I needed to see. Upon arrival, I was taken out to see my truck on a lift and shown a frame that was completely rusted out. The service manager poked a screwdriver into the frame causing pieces of rust to fall to the floor exposing a hole in the frame. I was also shown where the frame was cracked right under the gas tank. They offered no explanation when I asked why they had not found this problem when they diagnosed the problem with the gas tank. All in this past year a the same dealership, I have had my truck in for new tires and shocks with no mention about my rusted frame. They blamed the rusted frame on the salt brine used on maine roads during the winter months. I was told my truck was pretty much worthless. When I asked why chevrolet didn't built frames to better resist the salt brine they offered no answer. I have taken my truck to multiple car shops where they reported they see this frequently and the only thing I can do is either sell my truck for parts or replace the frame which would cost in excess of $15,000. I can't imagine that my truck is an anomaly and wonder how many other people might be driving a vehicle that looks almost new like my truck does but has a rotted frame. Toyota recalled their tokoma trucks due to this same problem. I am hopeful something can be done. Other than the rotted frame on my truck the rest of the under carriage is pretty much pristine.

The ignition will not start at first. It takes multiple times in order to get the engine to turn over. Once the ignition does cause the engine to turn over, the vehicle will suddenly lose power while driving as the vehicle shuts itself off (as if the ignition has been turned off although it has not been). This has happened on multiple occasions in the course of normal driving activities, several times while crossing busy intersections which luckily has not resulted in any crashes to date, but may very well result in a potentially fatal one should it continue to occur. Engine has been tested and all systems check out, except for the ignition switch which -will- have to be replaced.

With the revelation of the gm ignition recall problem, there are much more ignition problems that were not included in the recall. The problem is in the ignition cylinder and alignment with the passlock or passkey sensor. My problem started shortly after the vehicle went out of warranty and I was told by the dealer that it was a $1000.00 repair. I can not afford $1000. So I have lived with it. Because of the misalignment it causes the ignition to think that the vehicle is stolen and disables the fuel injectors, it has left me stranded quite a few times along the road waiting for the computer to manually reset after 10 minutes, it has also cost me several towing bills until I did an internet search and found out how widespread this issue is. If the misalignment is causing this to happen what will it affect as the problem worsens. This issue is not covered by the current recall but deserves investigating .
