2018 CHEVROLET SILVERADO 1500 Complaints

The following Recalls were found on Kelly bluebook, that matched the issues I have been having with my vehicle perfectly. When calling the recall center, they stated my vehicle year 2018 Chevy Silverado and serial number were not listed for this but it's the exact diagnosis of what I'm experiencing. The Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash. As the vacuum level drops, the brake assists decrease, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. A decrease in brake assist can increase the brake pedal effort and distance required to stop the vehicle, increasing the risk of a crash. What component or system failed or malfunctioned, and is it available for inspection upon request? The brakes inflate on their own as if someone is pressing them down while driving. The vehicle begins to jerk horribly causing the inability to steer or maintain control of the vehicle or the ability to stop. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes How was your safety or the safety of others put at risk? This is very dangerous. I have no control over the speed of the vehicle or if the brakes will fail, or if the brakes will burn up due to fighting with the accelerator while driving. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, the manufacturer inspected it and stated they could fix the issues, paid but then the same malfunction kept happening even after payment and supposedly being fixed. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None related to the issues, Stabilitrak warning and then random hill assist to inflate the brake vacuum

P1. On or about Feb 9, Power Train transmission, Modular’s. While traveling about 40mph the truck shifted suddenly to low gear, and the water pump blew resulting in steam or smoke from engine hood. Automatic shifting was not possible, after slowing to 5-10 mph check if mauls shifting was an option. All gears L1 L2…were replaced with ‘L’. P2 March 2023 to presented 2024, the vehicle will vibrate and shake. More like a shimming. This happens what seems to be every .5 to 1.0 mile. P3 March 2023 The Transmission issue listed in para 1 happen exactly as describe above. Except the water pump was fine. On or about June 2021 The Transmission issue listed in para 3 happen exactly as describe above. I TOOK TRUCK TO HENDERSON CHEVROLET in Henderson , NV and reported the transmission sudden shift to low AND how the truck slams into gear when leaving a stop sign light. It feels like someone hit the back of the truck. Jerks forward. Service RESULT: that’s normal for the truck. October 2019, took truck to back to Circle Chevy / Hyundai in Shrewsbury NJ regarding the slamming and jerky transmission. RESULT: it’s normal or it didn’t do it while in service road test. I just bought the truck 1 month earlier from CIRCLE CHEVY of SHREWSBURY NJ. Regarding the most recent trans issue of Feb 2024, the power train went out of warranty in August. The issues should have been fixed when odometer was between 000064 to 60000 or Aug 2024. This truck is unsafe and sudden shift to low gear can cause the truck to get into accident

The high pressure fuel pump has failed at only 60,000 miles. My Safety along with the safety of others has been put at risk from major loss of power... not safely stopping the vehicle due to fuel pressure malfunction. Certified Chevy Dealer diagnosed high pressure fuel pump Come to find out from the dealer... a warning sign was the electric start button not working. Engine light did NOT come on till after the truck had major power loss/ misfire/ stall.

Rear sliding window with defrost started sizzling sound than emit a bunch of smoke into the cab. Shut off rear defrost, preventing a fire. The window than shattered. There is a recall in Canada for this very issue. We live only a hour south of the Canadian border. GM says Canada get colder so that’s why the issue is up there.

Rear window defrogger overheated and caused the back electric sliding window to shatter and when door was closed the window blew out!

Vehicle wouldn't accelerate while in moving traffic. Rpm gauge would move but speed gauge would not and vehicle would not accelerate past 30-35. When I pulled over and put my vehicle in park then attempted to put in drive, it would not move. Transmission light turned on. Had it towed to a mechanic who after diagnostics, states it's definitely the transmission/torque converter.

Vacuum Pump is leaking oil and internal components are rattling indicating imminent failure and that is a safety hazard for the vehicle and passengers. Oil is being slung all over the front of the engine and multiple belts creating additional operating hazards for the vehicle and passengers. There was a recall concerning reprogramming software to reroute air pressure to the brake system and prevent total failures. Also, technical service bulletin addresses related issues to vacuum pump failures and other affected system components. My vehicle is available, no one has looked at it, we are in danger every time we ride in this condition, no indication of failure other than those already stated. My truck is going on 6 years old and 118K miles. Hardly the time for a brake system failure for a normal use vehicle. This is a safety hazard that GM has created by utilizing faulty components and should be treated as such with all vehicles affected recalled for replacement before vehicles and passengers are seriously injured.

While driving my 2018 Silverado, the 5.4L, 327c.i. engine began idling very rough, shaking and periodically stalling. The check engine light began blinking and it threw codes PO308 & PO301. After compression test & new plugs/wires, it was found that the injectors had open circuits on injector #'s 1 & 8. The only way to replace the injector is through the bank. In this case both banks 1 & 2 were affected. Cylinder #1 is through bank #1 & cylinder #8 is through bank # 2. After removing the intake manifolds and injectors, it was found that the injectors were not providing fuel to the engine causing a misfire on 2 random cylinders #1 & #8. Called the dealer to order parts and discovered they have already been superseded. Original part# is 12698484 and it has been superseded by part# 12710481. Then injectors were replaced & new intake manifold gasket installed w/ proper torque. After repair completed and engine tested, the problem was resolved. Repair shop's invoice will be attached for reference.

Last night the truck wouldn’t turn on. The battery had died 4 days after the car was serviced at a local Chevy dealership. I turned the truck on this morning, with what seemed like it didn’t want to turn on and now I’m getting an alert “trailer brake system” i will be contacting the dealership once it’s open
