Passlock system this has been going on over the last three years and now getting worse and is intermittent, when I insert and turn the key something happens making the theft system activate and keeps the vehicle from starting for exactly 10 minutes. Recently I turned the truck off to save gas while I was in construction traffic at a stand still with a concrete barrier on both sides and the truck would not start and the police were going to have me towed, luckily at started at 10 minutes before the tow truck came. In my opinion this can be unsafe in emergency situations if the vehicle is needed for any type of emergency. Below I am pasting something from the web, but it is basically the problem that I and people all over the country are having. "thousands of people are being led in circles by any vehicle with a passlock II system and it is an unsafe problem with these cars that needs to be fixed. It prevents vehicles from restarting in potentially dangerous areas while the vehicle resets and can permanently disable the car if not addressed. The problem lies in a design oversight and cutting a material cost by putting in a cheap component that any basic chemist could tell you would go bad within a year or two. Change your ignition switch contact from nickel to gold plated connectors and oxidation will not cause faulty readings to trick your vehicles into thinking that they are being stolen and shutting off the fuel pumps. Remuneration for individuals impacted by this financial burden for the purchase of your vehicles is also a request as this problem is a gold mine for car mechanics, both GM certified and freelance, to troubleshoot numerous systems before identifying the problem proper."

[xxx] [xxx] wichita Kansas 67203 retired [xxx]@yahoo.com [xxx] highway message: Anything on General Motors use of the pass2 security system, it randomly will not "read the key", at which point you must wait 15 min. To try again. Have talked to 2 other people with the same issue in the last month in my area. Talked with my local dealer and all they would offer is to replace the ignition switch, at my expense of course. Dealer stated that they were aware (GM) of it as they are now on security system pass4. This could become a safety issue if the vehicle would not start and was in a suddenly hazardous area. Dealer offered to assess my vehicle, problem it may not happen again for another month or more, although it happened to me on the 9th of November 2015 and again on the 11th. Can't really afford to be without my vehicle for that long. My vehicle is a 2008 GMC Canyon. The vehicle was stationary, it has happened a total of 6 times.

About 3-4 days per week the truck will not start. We have to take the key out of the ignition and let the truck sit for around 10 min. And then the truck will start, or if it does start the components on the dash and the radio does not work and we have to wiggle the switch to get it to work.

About three to four times a week my vehicle will not start and I have to remove the key wait ten to thirty minutes reinsert the key then the truck will start. Several times a week I must shake the key to get the dash board and radio to work therefore allowing the vehicle to operate, tho the vehicle switch has not been recalled, although several other GMC vehicles have.
