Check engine light came on, I plugged my code reader in and was given P0498 ERROR CODE. Upon doing research and calling around to 3 different Chevrolet service centers I was told that it is a know issue with the fuel pump control module on all gm trucks. I am part of a truck group of over 150 and 85 of us has had this issue and all are currently waiting for the part to come in which is back ordered over months. Why has there been no recall and service bulletins yet if all 3 of the service managers agreed of the known issue.

While driving the engine jumps/jerks then goes back to normal, it continuously happens every 3-5 minutes while driving. A friend had his exact issue with exact make model year vehicle and it ended up being the gas sensor. Please look into this issue for this vehicle. Our local dealer will not fix it because the sensor doesn-??t show the issue but that is the issue. The dealer knows it does it but won-??t fix it.

while driving i smelled what i thought was strong exhaust from a vehicle in front of us. It was actually gasoline fumes entering the cab from my truck's engine compartment. I pulled over and investigated the smell, we had to let down ALL the windows and turn off the AC. There were no warning lamps. There was, however, gasoline dripping from around the transmission area of the underside. It was dripping on the exhaust which was causing most of the stench. It wasn't a heavy drip but enough for me to skip any other planned errands. When we got to the house gasoline was dropping from six or seven places under the car. The next day we set an appointment for the dealership to look at it. When I drove into the dealer the car was still gushing gasoline and I told them about the recall for the High Pressure Fuel Pump. It turns out that's exactly what it was. However, although my RPO (L82) matched the designated recall, I was told my VIN was not included and I would have to pay...bummer. I don't think the recall cast a big enough web to catch all affected vehicles. I have a video but no photos.

Vehicle didn't start; got stranded. Tried to jump start with another vehicle. It turned, but didn't turn on. Had it towed to mechanic (closed on Sunday). Was lucky to be in an area I was familiar with during the day and not traveling over 250 miles the following day with family at night. Mechanic called Monday and stated fuel pump has to be replaced after a diagnostic test. 2020 Chevrolet Silverado @ 50,000 miles

My truck had been randomly misfiring but the dealership couldn-€™t resolve the issue because the check engine light would go away on the way there. They were able to pull codes showing a misfire taking place and told me to return if it continued. The truck started having misfire issues again periodically fir the next 2 weeks but once the check engine light stayed on I scheduled an appointment. On the way to the appointment to Hidiburg Chevrolet we were on the interstate the cruise control kicked off, the service parking brake indicator, misfire flashing of check engine light, an ESC warning, and the traction control light came on as the truck randomly pulled to the right real quick then it stopped. Once the indicators went off all warning indicators were off and cruise control would not work. The dealership pulled codes and saw every cylinder misfired and that the other issues that took place. They tested everything and could not find the source and said that they had to wait until the indicator stayed on so they could see the issue. I left with no resolution and concern that when the misfiring could damage parts and the computer. I also fear that the issue if someone isn-€™t aware of vehicles not fixed could lead to severe accidents and potential for death if not fixed.

High Pressure fuel pump failed external fuel leaking onto exhaust of truck. Lucky the truck didn't catch on fire. Would have if I kept driving. What component or system failed or malfunctioned, and is it available for inspection upon request? High Pressure fuel pump (external leak) under GM warranty they have the parts. Flannery Chevrolet Bad Axe MI How was your safety or the safety of others put at risk" Gas leaking on Hot catalytic converter and cross over pipe. Skid plate was full of fuel. A fire under the truck would have made it very difficult to get out of the vehicle once stopped. Has the problem been reproduced or confirmed by a dealer or independent service center? Towed vehicle to dealership and they diagnosed High Pressure fuel pump leaking. they replaced the pump and appears to he resolved now. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not that I know of. GM warranty covered repairs. Vehicle only has 13, 720 miles on it. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" Driving down the road started to notice a really bad fuel smell and after stopped you could hear the fuel hissing as it dripped on exhaust pipe. Vehicle sat for 10 mins and had puddle of gas under the front of the transmission. Start the engine again and it continued to drip. I Called towing to come get it.

I was stopped N the drive thru at in-N-out with my foot on the brake and the eco system had turned off the motor. It spontaneously turned back on without me lifting my foot off of the brake and the transmission engaged and the truck launched forward approximately 12-18 inches. This is the second time this has happened to me. It also happened one night about 2 months ago. This could have been very dangerous, I could have hit someone or their car or I could have even received whiplash myself.
