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.

Heavy smell of gasoline in the cab and the bed of my truck as well as outside of the truck began on February 23, 2023. The truck is also harder to turn over or start since the smell has begun. Due to the gasoline smell, it is causing a nauseous feeling, severe headaches, coughing and a red flush over my wife’s face when she is in the truck. The transmission line leak has been leaking for quite some time and I have to replace the transmission fluid a least a quart of fluid every two weeks. I was not notified of the Safety Recalls for the Fuel pump pressure regulator and the Transmission oil cooler line leak/ fire danger on my 2014 Chevrolet Silverado 1500. I have taken my truck to be assessed by the Chevrolet Dealer on 03/13/2023, and they determined that my truck does indeed have both of these Safety Recall problems but that they will not repair them. They stated it is a closed recall and my 95k+ miles were too high. The Safety Recall Bulletin #14121 and #13370A both state no mileage limitation and declare my make and model affected by these Safety Failures. I have paid off the loan to my truck early only to be unable to drive it safely or enjoy it. I have never been late on any of my payments and was proud to pay it off early. This model truck has had several Recalls including an incident with the front wheel falling off due to a mechanical failure, that was shocking and frightening when it happened after only owning it for approx. 2 years. With the Fuel leaking and carbon monoxide, and the transmission fluid leaking, the Dealer should take responsibility and repair these problems that they know are a Safety and Fire issue as stated in the Recall Bulletins and make my vehicle operable again. I am only asking that the Dealership provide me with the Repairs they said are needed to the Failures caused by improper installations and or Faulty equipment from the manufacturer as stated in the Safety Bulletin Recalls.

2014 Chevy Silverado. Drove the truck 0.9 miles from my residence to bank to withdraw money from ATM. Noticed a strong fuel odor when I exited the vehicle. Verified fuel leak while the truck was running. Had the vehicle towed to local Chevrolet dealership where they inspected and confirmed Fuel Leak under the manifold. Removed intake and found low pressure line, at the high pressure is blown off. All 4 retaining tabs were broken and secondary latch was laying off to the side. No warning lamps and no other symptoms were noticed prior to failure. No tampering or previous repairs in area. This is a major safety/fire risk, l am lucky no one was hurt.

My 2014 Silverado had a hose leak in 2018. Three years later I have the exact same issue. It’s a refrigerant leak. It has not been inspected this time around because it’s clear that this will be an ongoing expensive problem that I cannot afford. It’s in the 100’s out here and even hotter in a vehicle. My family and are getting sick from heat exhaustion I need immediate relief, please.

I CHOSE A USED 2014 CHEVY SILVERADO WITH 180K MILES. I MET MY SALESPERSON, BERNARD, ON SITE AT PUGMIRE FORD, IN CARROLLTON, GA. WHEN I TEST DROVE THE VEHICLE, THE TRUCK HAD OFF ROAD TIRES, SO I REQUESTED THAT PUGMIRE PUT REGULAR TIRES ON THE TRUCK BEFORE TAKING POSSESSION. THEY AGREED AND THE TRUCK WAS DELIVERED A FEW DAYS LATER. SOON AFTER DELIVERY, I NOTICED A SOFT NOISE SEEMINGLY COMING FROM THE ENGINE. I INFORMED MY SALESPERSON BERNARD OF THE ISSUE. HE ASKED ME TO BRING THE TRUCK BACK FOR REVIEW. I DID & BERNARD TOLD ME 'IT HAD SOMETHING TO DO WITH THE EXHAUST SO DON'T WORRY ABOUT IT. IT WILL GO AWAY AFTER A FEW DRIVECYCLES'. I DIDN'T BELIEVE HIM SO I HAD THE OBD CHECKED, THAT INDICATED THAT THE CATALYTIC CONVERTER HAD FAILED. I SENT THE DOCUMENT TO BERNARD, THEN I ASKED IF THE VEHICLE HAD A RECENT EMISSIONS INSPECTION, HE SAID HE DIDN'T KNOW. HE APOLOGIZED, BUT STATED THAT THEY WOULD NOT BE RESPONSIBLE FOR ANY REPAIRS TO THE VEHICLE. AT THIS POINT, I REMINDED BERNARD 1. IT IS ILLEGAL TO SELL A VEHICLE THAT CANNOT PASS EMISSIONS 2. THAT MY BANK HAD NOT YET MAILED THE CHECK. WITH THAT MIND, PUGMIRE FORD FINALLY AGREED TO PAY FOR THE REPLACEMENT OF THE CATALYTIC CONVERTER. SO I AGREED TO AUTHORIZE MY BANK TO SEND THE CHECK. PUGMIRE HAD ARRANGED FOR THE TRUCK TO BE FIXED AT G&S AUTO AND THEY PAID FOR THE WORK. BUT AFTER REPAIR, THE CHECK ENGINE LIGHT RETURNED. SO I TOOK IT BACK TO G&S TO ASK WHY. THAT'S WHEN THEY DETERMINED THE CATALYTIC CONVERTER HAD FAILED DUE TO INTERNAL ENGINE DAMAGE. THEY RECOMMENDED ANOTHER SHOP FOR A 2ND OPINION. THAT SHOP IS CALLED ALL PRO AUTOMOTIVE. ALL PRO CONFIRMED THE DAMAGE AND PROVIDED A QUOTE FOR THE REPAIRS. PUGMIRE FORD VOIDED ALL CLAIMS OF THE VEHICLE BEING AN AN 'AS-IS' PURCHASE WHEN THEY PAID TO REPLACE THE CATALYTIC CONVERTERS. THEY TOOK OWNERSHIP OF IT, AND OPTED OUT AFTER THEY RECEIVED THE CHECK FROM MY BANK.
