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.

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.

When my speed decreases to slow for a turn, traffic, red light,etc-I lose complete power in my entire vehicle. A too fast message pops up on dash about Stabilitrak. If I throw it in neutral fast enough it’s fine, but if I don’t, my truck loses all power and I have to open and close my door, restart my truck, the dash tells me to open and close my driver window, and it drives again but my time and date restarts on my dash screen like I disconnected the battery. It doesn’t happen every day. But when it does, it’s scary because I can’t get out of the road. This occurs unexpectedly several times a month for the past few months. I’ve checked for loose battery cables, etc

EVERYTHING, it started with spark plugs and boots which is normal, then all of a sudden one ignition coil after the other, then the transmission, now it's the valve cover gaskets, the ENGINE oil cooler lines, the rear main seal, the oil pan itself, like literally everything. The places I took it advised probably getting a whole new engine. Mind you I just financed this truck 2 years ago. The transmission cost me $6,700 dollars out of pocket because my power train warranty wouldn't cover it because some wire. I don't know but there is seriously big problems with this year make and model. Also, the catalytic converters are bad and the exhaust manifold. All these things can't be wrong all at the same time unless there was a major issue prior to me financing when Chevrolet spit these trucks out.

I was driving into a parking doing less than 10 mph trying to angle park my truck. Suddenly my truck accelerated violently hitting another vehicle in the parking lot in the right rear and turning it around. Was hitting the brakes to no avail. Truck continued to accelerate and I aimed for a sign support pole while depressing the brakes as hard as I could. Truck hit the pole and the air bag deployed. Front of my truck was caved in and the truck was ruled unrepairable by my insurance company. I could have been badly injured or killed but thankfully sign support pole stopped me. Have a police report but was unable to scan it to my PC so I said there was no report.

I have experienced engine failure in my 2014 Silverado 6.2L on 3 separate occasions. All caused by the AFM system. Rockers lock into the wrong position while transforming from 4 cylinder to 8 cylinder operation. The first two occurrences bent lifters and caused a failure to the catalytic converter. A certified GM service department at a local dealership replaced parts covered by warranty. On the third occasion the rockers locked into the wrong position, bent push rods, damaged the cam shaft and caused a failure in the catalytic converter. It was taken to the same GM service department at Lou Fusz Chevrolet. My 5 year warranty had expired and GM refused to cover the parts they had previously replaced a year prior. I was quoted approximately $10k for repairs and $16k for full engine replacement. After some back and forth with the service department manager I requested to speak with the lead mechanic. He informed me that it was an AFM system problem he was very familiar with. He stated to me that I would be better off taking it to a private shop and bypassing the AFM system as he was “working on” 10-15 vehicles a month with the same issue. At the time I had reached out to GM corporate about the issue and I did not receive a correspondence. I have all of the paperwork and receipts and all other service records dating back to my purchase of the vehicle in 2018.
