2014 Chevrolet Silverado 1500: gas smell in the cabin

Filed Nov 17, 2025 · Fuel system · MI

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.

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.

The air conditioning condensers are known to be defective by gm and several local dealerships as well as local mechanics who are constantly replacing these on vehicles equipped with the 5.3l v8. This applies to all gm vehicles with this motor. Owners are unable to get this fixed as oem parts are on national back-order with no eta. The back-order is due to gm having to re-manufacture the entire inventory while overwhelming demand for these replacement condensers grows. This is a $1,100 repair including parts and labor that should not be the burden of the consumer as gm has acknowledged this is due to a manufacturer defect. In the meanwhile we have to drive with our windows down which exposes us to exhaust fumes of other vehicles and debris being free to enter the vehicle. Nothing provoked this failed condenser as I was simply driving down the freeway at a normal speed and my air conditioner quickly became warmer as the refrigerant leaked out.

The truck has a raw fuel smell under hood and drawn in the cabin when the engine is running both while stationary and moving. Attached is len lyall chevrolet's diagnosis of leaking high pressure fuel lines under the intake manifold. This vehicle has been driven 40,866 miles. I was told this is not covered by powertrain warranty but by the 3 year 36,000 mile warranty. There is one (tsb #15-na-002) and two recall/ campaigns (#14858 and #13331) for this known failure. This is a safety, health and emissions concern due to possible fire, high/ failing evaporative emissions, and respiratory health problems. I feel this vehicle system failure should be covered by warranty or emissions warranty.
