2018 Chevrolet Silverado 1500 complaints

The plastic fuel pump module (GM part # 13510918) has cracked. The top flange that rests against the top of the fuel tank has an approximately 3 inch crack. The indications were a failed EVAP Check Engine Light PO442 (Small leak). The vehicle had less than 35K miles at the time. Contacted dealer who stated that it was a common problem. Also contacted GM but they provided no assistance. This crack could lead to fuel leaking from the top of the tank. The issue required the fuel pump module assembly to be replaced.

I have a 2018 chevy Silverado 1500 crew cab, I’ve been having problems where the truck warning light would come on saying “service stability control” and the truck would turn off when reversing and while driving on highway and the light flickers and the steer wheel would lock up as well, please help me out, I have searched over the web and have seen other people posting about it and having the same problems but yet Chevy has not done anything about it, this is a safety hazard

Torque converter failed resulting in failure of transmission. Requiring complete replacement of transmission at the cost of $7100 from dealership.

The component or system that failed or malfunctioned, FUEL PUMP ( METAL FLAKING IN FUEL SYSTEM ) has caused 1 or more CYLINDERS to FAIL. It is available for inspection upon request. My safety as well as the safety of many other motorists was put at high risk due to the fact that I had a 40ft. trailer hitched to the truck at the time the engine power was reduced. thus causing my vehicle to loose power while driving on a major highway. The 2018 Chevy Silverado was diagnosed by the Chevrolet Dealership doing-business-as ASCHENBACH CHEVROLET located at 925 East Main Street, Wytheville, VA 24382. The vehicle has not been inspected by the Manufacturer. When pressing down on the gas pedal, the truck would not accelerate as normal, then a message appeared on the dash-screen ENGINE LOOSING POWER.

At random the touch screen/radio will continuously switch through screens and apps while operating and will become extremely warm to the touch. The display screen on the instrument panel will also scroll through randomly. The heat will stay on continuously even though it is off.

Turned on rear window defrost and unit started smoking badly with a chemical smell while driving truck. I pushed button to turn rear defrost off so it wouldn't start on fire but the unit had heated up so badly it shattered the window it was touching.

UNKNOWN I had performed preventative maintenance this evening, fuel filter replacement and noticed after I pulled the fuel filter from the housing and tipped housing back upright, there was what appeared to be brass/gold metal shavings in the bottom of the housing in a little puddle of fuel. If there is metal shavings in the filter, that is a problem. Not sure if it would be fuel pump, or lift pump. Truck runs fine, I do get some hesitation from time to time, but not always. No warning lights/indicators, no water in fuel indicator, or presence of water in fuel. I am worried about safety if metal shavings contaminate entire fuel system, plugging injectors shutting down the truck on the interstate.

The GM 6L80 transmissions have a faulty torque converter. When it goes out it causes a horrible vibration and drive train failure. Which leaves you stranded in traffic or on the side of a busy highway. These transmissions have been installed by GM since 2013 knowing they fail prematurely as early as 60k miles. It’s a running joke that this transmission saved repair shops because of the sheer amount of failures. With the cost passed on to consumers. There are several in detail breakdowns of the defect in this part on various social media platforms and Internet forums. You can call any transmission shop across the nation they can confirm the defect. There where no warning lights prior to, during, or after the failure.

GM has produced millions of vehicles with the 5.3 motor with AFM,DOD,VVT issues. They are well aware of this issue. The factory defect causes the lifters to collapse causing catastrophic engine failure. This posses a hazard to consumers in traffic trying to navigate their stalled vehicles off the roadways. GM customer service is rude and dismissive, furthermore they offer no assistance to fix these problems. The issues with these motors is well documented and any repair shop/ dealership can confirm these issues. There is no indication from warning systems prior to this failure. However there are multiple Dash warning lights after the catastrophic failure occurs. The cost is passed to consumers to address these issues.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that the Stabili-trak warning light was illuminated. While driving approximately 60 MPH, the vehicle stalled. While making a turn at 40 MPH, the vehicle shut off. The contact used OnStar to perform a diagnostic test, and the result was a failure with the fuel pump. The vehicle was taken to the local dealer, where it was diagnosed that the fuel pump needed to be replaced. The vehicle was repaired, but the failure recurred. The vehicle was taken to another dealer, Chevrolet of West (225 T M W Pkwy, West, TX 76691) where it was diagnosed that the battery fuse box and ground cables needed to be replaced. The vehicle was repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 41,000.

Upon light acceleration of the vehicle, a rough gearshift occurred followed by a check engine light and the vehicle continued to shift roughly and idled roughly. After months of diagnostic work and attempts at repairs, it was determined the lifters were the issue. From independent research I understand this is a somewhat common (and pricey) issue. I’m not sure why there is not a recall for the cheap lifters, but I would like to pursue possible reparations for this fault of GM that has left me without a vehicle and left me with a great financial burden for over six months.

Brake caliper warped

Service Trailer brake light would ding and appear randomly while parked and driving with no trailer or load hooked. Radio jumps screens making phone calls disconnecting Bluetooth just spazes out. Truck is currently sitting at the dealer suggesting a TCM repair. Truck will be in Drive and roll backwards. Driving down the road vehicle just goes limp.. no power nothing. Absolutely disgusted with my purchase and what I’m going through with my 2018 Silverado

Without warning engine stalls

I FEEL THAT THIS IS A DEFECT IN THE WIRING SYSTEM AND NEED TO BE RECALLED ON THIS ISSUE. I SEE SEVERAL COMPLAINTS ABOUT THE SAME ISSUE ON THIS MAKE AND MODEL. TOOK TO DEALERSHIP WHERE I BOUGHT, AND WARRANTY OUT. 2018 MODEL AND KEPT BLINKING ON AND OFF WHILE DRIVING. FOR SAFETY REASIN I NEED THIS REPAIR TAKEN CARE OF. NEED A RECALL SO CAN BE REPAIRED AT KNOW COST.

Have had two different door actuator/locking mechanisms fail on both rear doors. This is an easy part to replace and is able to be replaced by the consumer. Both times it was replaced the actuator failed immediately in the locked position. Door could not be opened from the inside or the outside and had to have door panel cut off to reopen. After the second failure, the GM Dealer tech showed me a "trick" that was only known to GM techs and that if the consumer did not replace the latch with the undocumented "trick" and only used the standard repair manual the latch would fail as such. I approached GM for an answer on this and they stated that I am not a licensed GM technician and should not attempt to do anything on my vehicle other than put gas in it and drive it. While I do understand that at times it is necessary for a trained professional to be involved, but that should not be the case for a door latch. The lack of concern on GMs part as the door had to be cut off because of this is irresponsible. There are plenty of other stories of the same issue occurring with this same style of latch. Someone could easily be trapped in the vehicle with this issue and killed.

The truck excellerate when I stop at stop sign or red light, with my foot on brake pedal acts like it is going to take off without my foot on gas

The transmission caused a vibration and sometimes a surge when it would go into gear. I had to be very careful when initially driving forward, especially in heavy traffic making sure I had a safe distance ahead of me. The entire vehicle would shutter when accelerating almost at any speed.

My 2018 Chevy Silverado 1500 keeps stalling/dying when making turns. There is zero correlation to speed, stop and go, slow, fast, sharp or gradual turn, acceleration or slow rolling start, hard stop then start. It happens mostly when turning right, or left, mostly right. It 's happened 12 times from July '22 to January '23.Dash only shows mileage when it dies. (digital). Rest of console is black (similar to when remote started). It has happened when remote started (twice), other times when manually started with the key. I have tried to recreate stalling turning/starting fast/slow/sharp, etc in empty parking lots while videoing multiple times without success. I took it in to dealer's service center in January '23. They trouble shot it, determining that it was a faulty fuse box and changed that out. It has continued to occur despite this "fix." It has occurred 8 times since January, four of those times in the last 3 weeks, twice on one day. All of these times, except yesterday, I was lucky that no one was behind me. Yesterday, it happened when I turned left. I was able to place it in park restart, and continue. I stopped at stop sign, then turned right. It died again while a truck was behind me. Because it had happened so often, I shifted into neutral, restarted engine, shifted into drive and was able to get enough speed to avoid them hitting me from behind. I was luck the other driver noted that I had stopped and slowed down accordingly. Had I been in heavy traffic, that may n

The vehicle has just completely died on me at least twice while driving it, the power steering keeps cutting out, and the headlights will dim significantly upon pressing the brake pedal or using turn signals. This has been going on intermittently for months. Upon an internet search, this does not appear to be an uncommon issue.

My back up camera is blue. It works intermittently. There is a recall on the exact same problem for 2019 but not for mine. https://static.nhtsa.gov/odi/tsbs/2019/MC-10160418-9999.pdf I don't understand that but it is what it is. I am not paying for it to be fixed since it is an issue in the following year. I don;t think I should have to pay for a software issue. I just thought I would report it. Maybe there will eventually be a recall.

Back in December of 2018 when I got my truck it only had a1000 miles on it and it has been down shifting hard it jerks hard I have reported it to the mechanic at the dealership at Mitch smith in Cullman Alabama and that said oh it’s supposed to do that well now it’s out of warranty and they said it needs this that and the other

Vehicle started to fill with smoke. I exited vehicle to look in the back seat when all of a sudden the rear window exploded causing glass to come flying at me. There was a recall for this exact same issue, however gm says this vehicle is not included in it. Obviously there are more vehicles that need to be recalled!

My vehicle has been properly maintained since new. At around 90,000 miles the transmission started making noise. I had trans filter changed and the noise abated. at 92,000 the car started shifting oddly. Several times on the highway the engine would rev and the car loses speed. Loud noises from the transmission and hard shifts. I most recently was unable to accelerate while getting on the highway. This is a truck, I have things I have to transport. I am unsure if I should continue to drive on the highway. I am going to my local dealer next week to explore repair options. I have learned that this problem is well-known to GM .

For about a month I heard a clunking sound in the steering wheel shaft when I initially started the vehicle and turned the steering wheel. After a few miles of driving it would go away. The vehicle then began to have a hesitation when I would try starting it. Diagnosed as two cells were dead in the battery. Replaced the battery and the steering improved. Two weeks after replacing the battery, I started the vehicle and started to turn out of a parking spot. At that time the steering wheel refused to turn and it sounding like a pump going out. The service steering warning came on. I got it to the dealer and they diagnosed the electric rack and pinion drive belt had broken and sheared the gears in the assembly. The vehicle is a 2018 Chevy 6.2L High Country with 71,000 miles. I was told by the dealer that if this would have happened while driving at highway speed it would have locked the steering wheel in the position at the time of component failure and would have more than likely resulted in a crash. Currently the vehicle is still at the dealer for the last month waiting on the rack and pinion to be shipped. Apparently there isn't any of these parts anywhere in the United States.

RECEIVING A PERSISTENT 'SERVICE - TRAILER BRAKE SYSTEM

While on the Interstate with cruise control on, my truck started to vibrate while on highway, then shakes so badly it becomes difficult to grip steering wheel firmly. Slowly came to a stop and checked all four wheels. Waited on side of road until engine cooled down somewhat and then got off highway at next exit and made my way back home on side streets NOT DRIVING OVER 40-45 MPH. Vehicle is currently at dealer Service Department. Said it is normal, but transmission would be checked.

:Service Trailer Brake" warning comes on on every start up with no trailer hooked up. The warning can usually be dismissed, but for 40 minutes one time ,it constantly came on and off constantly. Could not get it to stop. Very distracting and dangerous. An independent repair shop has confirmed the condition, but unable to diagnose problem.

My engine cooling lines are leaking and that can potentially cause a very bad problem to my engine itself imagine I'm driving and they pop off causing me to lose all my oil and then my engine can drown and sudden stop while I'm on the highway I was first aware of the problem when my veichle had to be taken in because the transmission was failing at around 55000 miles the dealership told me about this problem which said did not need to be addressed since it's a small leak on the lines but once I got down under my truck and took of the undercover it's more than a small leak now I'm facing having to spend money on a veichle that should not be giving me problems yet at the miles it's at I'm trying to get a hold of my extended warranty to see if it's covered because chevrolet said it's not there problem anymore yet I'm not the only one with this exact problem upon investigating the 2019 had a recall for this exact problem the engine cooling lines and I had notice I had to do more oil changes way faster but never thought it was that
