Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

My 2015 Colorado Z71is experiencing moderate to severe hesitation concerns. It's progressively getting worse. I first brought it back to the dealership to have it checked out around1000 miles, 6000 and now 20000. Each time they claimed they can't do anything because the diagnostics reveal no trouble codes, although, per aforementioned bulletin, there's proof that a problem exists. I inquired if it could be a mechanical issue, but they refused to because no diagnostics produced no codes/proof.

Engine stalls intermittently when beginning to accelerate from red light/stop sign. Stalls occurred within 1 mile distance from where vehicle was started. First stall was at red light moving forward lightly. Sifted the vehicle to park, turned key, vehicle turned over and was able to drive once put in park. The vehicle was immediately taken to the Chevy service center. The service advisor was able to read an error code P0506 even though the check engine light was not illuminated. Chevy could not schedule an appointment for the vehicle until 5 days later; the error had cleared and they were unable to duplicate the problem. Service department declared vehicle safe to drive as it the issue couldn't be duplicated. Engine stalled a second time when beginning to cross road at a two-way stop with oncoming traffic. Shifted vehicle to park, turned truck back on, shifted to drive and was able to move from intersection without being hit.. the Colorado was taken to the dealership a few hours later and the error code had cleared already. Service advisor stated the car was safe to drive and there was no work to be done as their were no warning codes and the check engine light was not illuminated.
