My vehicle produced a check engine light then it started to be hard to start . Then I started to smell fuel in the cab and strong smell of fuel under the hood . I cannot see the leak so it has to be the HPFP located under the intake manifold and the fuel is being absorbed by the insulation located under the intake. In January 2014 the GM corporation issued a voluntary or bulletin for this year truck and the 5.3,engine for having installed the wrong fuel regulator in these pumps. Bulletin number 13370A states this exact problem. This vehicle was produced in a Canadian plant therefore fell through the cracks in there recall/bulletin . This is a safety problem that I cannot get repaired under warranty or anything. This vehicle is prone to start on fire that’s why they issued the bulletin but since it was Canada born they really do not want to help me and say it isn’t on their recall list even though it is the EXACT problem they list . And since it isn’t on their recall list they won’t even look at the bulletin to see about goodwill warranty either to cover the repair. Why is this vehicle with the same year and same make and same engine excluded , because it’s made in Canada it doesn’t make the list of recalls in the GM world.

This in addition to complaint form number:11699917 I have found the two forms issued by the GM global corp. One is a recall the other a bulletin about the HPFP fuel regulator to be replaced because it was known to fail. The first actual recall (13370 ) states that 25,000 vehicles were involved. The symptoms they stated are all the same that the vehicle I own are having including fuel fumes in the cab and under the hood . In 13370 right at the top it states urgent so this problem is definitely a safety concern for fire or explosion. In 13370A they eliminated a lot of these details including the words urgent and the amount of vehicles that were involved in this recall. And at the bottom of 13370A it also states that the following two paragraphs does not pertain to Canada , THIS is important because my vehicle was born in Canada 🇨🇦. So everything stated above that involves Canada manufacturing also. So this means my vehicle should be included in this recall also like I stated in my complaint to this safety commission 11699917 . My vehicle has the 5.3 , it’s a 1500 Silverado and it’s a 2014. Recalls don’t expire for safety as far as I heard. There is no reasonable explanation as to why this vehicle was excluded except it was manufactured in Canada and fell through the cracks of their recall . Without a recall they will not look at any bulletin for this safety issue on my vehicle. This is a very expensive repair to be done and GM knows this also.

Vehicle purchased December 2020 Flashing check engine light that stays on- light did not stay on long enough for dealer to see, said they couldn't find any issues. The first time we had it towed and when they looked at it the light was no longer on. They were able to tell us what was going on with the vehicle when the light came on but said there were no problems. Flashing check engine light that turns off- "no light = no problem" dealer says. Eventually they printed pages showing engine misfires which we were initially told was no big deal. Later I was told I should get spark plugs changed, which I did. So far, flashing light has not reoccurred. Burns 3 or more quarts of oil between oil changes which I was assured by more than one rep that that was normal (on numerous occasions). Air conditioning quit working. Heater not working well and not at all on idle. The only setting I can really use to defrost and keep my feet warm is the "floor only" option. Mixed doesn't work, defrost only will freeze feet. Gas smell while vehicle at idle. Initially noticed when using auto start but have since noticed it does it with regular start as well. All issues have been brought to dealership, I will have to contact them for all the exact dates.
