2018 Chevrolet Silverado Complaint Log

10 degrees outside starter motor will freeze up and not want to start the truck. had 3 mechanics not a deal all look at it, tested the battery and came to the starter motor is defective. to have the starter replaced at the dealer for its under warranty.

My vehicle came equipped from the Factory with 18” wheels and tires and a 17” wheel and tire. The vehicle is equipped with 4 wheel ABS which fails to operate properly when using the factory equipped spare tire. GM recall a number of 2018 and 2019 vehicles with this very issue but did not recall my vehicle for this identical issue. I contacted GM who said if my VIN is not listed in the recall it is not an issue and they cannot correct the problem.

While driving in the daytime voltage at the dash dropped almost 9 volts but when I turn the headlights on, it goes back up to 14 volts I’ve had this problem since I got the truck January 5, 2022

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving approximately 45 MPH, the "steering assist reduced" and "service trailer brake" messages were displayed, and the steering wheel experienced a slight resistance while turning in either direction. The cause of the failure was not yet determined. The local dealer and manufacturer were not yet contacted regarding the failure. The VIN was not available. The failure mileage was 75,000.

The contact owns a 2018 Chevrolet Silverado 1500. The contact stated while driving 10 MPH, the check engine warning light illuminated. The contact stated that the remote became inoperable. The vehicle was taken to the local dealer, and the contact was informed that the repair was not covered under a warranty or service bulletin. The vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic, who stated that the motor on the active grill shutter was defective. The contact communicated with a GM engineer regarding the Technical Service Bulletin: PIE0500. The manufacturer was not notified of the failure. The failure mileage was approximately 48,000.

The transmission stopped working randomly on the highway after being driven for 45 minutes perfectly fine. Thankfully this happened near a stoplight so the traffic on the highway was going slower than normal otherwise it could have been very bad. Local mechanic confirmed that the transmission was no good and has ordered a replacement. There was no indication of the issue prior to the failure. No lights came on to indicate that there was an issue.

While driving my transmission will shudder and the vehicle will lose power causing the vehicle to slow down abruptly. It also will shift very hard making a loud noise.

While coming to a stop at a traffic signal I experienced a sudden braking loss. The pedal began to vibrate and I noticed an extreme reduction in braking power. I then got a prompt on my dashboard saying “service brake assist.” I narrowly avoided the car in front of me while trying to stop. I contacted GM and they claim even though my year make and model are the same as vehicles being recalled my specific VIN# is not.

Driving on highway 70 mph with out prior warning the truck begins to shake, backfire, lunging, loss of power, all the lights on the dash starting going crazy, cars behind me trying to avoid hitting me ,it wouldn't speed up, having a hard time getting it off the road and out of the way of highway traffic before getting rear ended by traffic behind me. The truck only has a little over 60000 miles on it which is just beyond the 60000 mile warranty, The truck lost compression because of a lifter failure in the motor. After this I have no interest in ever buying another Chevy product, If they cant build a motor that will last more than 3 years maybe they should rethink their future in the auto industry.

Trailer Brake Service Warning

radiator crack. and also looks like previous years have the exact problem and have a special coverage done on them, Special Coverage Adjustment 15829 Radiator Leak #PI1513A Bulletin No.: PI1513F

Bought the truck new. Never towed a trailer till well after warranty. Service trailer brake light keeps coming on continuously. Then no trailer lights or trailer brakes. Found 2 blown fuses but now the same thing is happening again. After my research I found tons of information that lots of other people are having the same issues. I have not pulled my RV since because I'm worried about it not having brakes. It's quite large and without them this truck would not be able to stop in case of a quick emergency.

Started vehicle and engine diagnostic displayed that the anti-lock braking system needs to be service, the power steering system needs to be serviced, parking assist needs to be serviced. This issued occurred one other time and a module needed to be replaced. This is the second time this has occurred in a year.

The torque converter failed internally allowing the torque converter clutch to shudder. The fluid exchange has already been done on RO#587959. Vehicle had 40k when torque converter was replaced. Issue arouse after a road trip to Houston Tx and progressive more at various speeds. James Wood dealership replaced the torque converter since it was still under power train warranty. When I researched online, I realized that this is a common problem within the 2014-2018 Silverado models. I hope I that after the dealership replaced this defected part I don't experience additional mechanical issue related to this faulty part.

Trailer brake system failure we noticed the sudden drainage of power resulting in death of battery multiple times alert was present after we notice the loss in voltage in battery to battery drainage after research I found that it is usually a short or a bad wiring harness which causes this and could pose a danger considering how I at one point in time have trilled things this could be an issue and a danger to others on the road

The contact owns a 2018 Chevrolet Silverado 1500 equipped with Continental Tires, Tire Line: Cross Contact LX20, Tire Size: 275/55/R20, DOT Number: A32AWD402917. The contact stated that while the vehicle was parked, the contact inspected the front driver’s and passenger’s side tires and noticed the threads were coming off in chunks. The dealer was made aware of the failure and informed the contact that there was a recall, but the tires were outside the date of manufacturing for the recall. The manufacturer was made aware of the failure but informed the contact that the tires were beyond the three-year warranty and did not provide any assistance. The failure mileage was unknown.

On 10/03/21 at approximately 1251 hours, I was driving my 2018 Chevrolet Silverado which is the vehicle with the above mentioned VIN. As I was traveling towards a heavily traveled intersection in my current city, I approached a steady red signal on the traffic light. It should be noted that this particular part of the roadway is a slight decline towards the intersection and traffic control signal. It should also be noted that on this particular day, there were no inclement weather or roadway conditions that would affect the vehicle to deviate from normal maneuvering. As I applied the brakes at a reasonable distance from the stop light, almost all pressure and power towards braking was lost. As a result, I was forced to apply extensive pressure to the brake pedal as the vehicle failed to slow and stop in a timely fashion. After gaining some braking power, the vehicle and brakes began to shake and produce a clunking sound. This was troublesome because had I failed to stop in a timely manner, I or other motorists could have suffered serious injury or death as a result of a crash at a heavily traveled intersection. Prior to this incident, there were no warnings or alerts provided by the vehicle, dealer, or manufacturer about this issue. As the event occurred, an alert flashed on my dashboard that read “Service Brake Assist.” Following the incident, my vehicle was inspected by a certified mechanic. Said mechanic deemed that the problem with the braking was a result of a failure of the brake booster vacuum system. After doing some research, it is apparent that other years, makes, and models of GMC products suffered the same issue with the braking system. Said issues were remediated with a recall by the manufacturer. This defect also caused numerous vehicle crashes with reported injuries.

When driving the brake pedal goes soft. In parking lots, areas of low speeds, making u-turns the brake pedal goes all the way to the floor and doesn’t stop. The brakes completely stop working until you release and pump the brakes again quickly before hitting something or someone.

My 2018 chevy silverado started making weird squeaky/popping sounds it almost sounds like something is rubbing against something else when stepping on the break pedal. When driving at any rate of speed the pedal seems to not make the squeaking noise but when I make a complete stop for example at a traffic light and let go of the break pedal and press again I can hear that noise loud and clear even passengers can hear it, Another example would be going in a drive thru of a restaurant that pretty much break pedal is used every 3 seconds as you pulling forward there the noise becomes constant every time stepping and letting go of the break pedal. My silverado has about 80,000 miles on it

Truck loses power driving down the road. The service trailer brake system warning comes on the dash. The battery dies because of this also.

The engine gave out at 60k miles. Only covered buy the extended warranty I bought. the transmission thunks on downshifts. The exhaust adaptive valve started making a terrible noise at 40k miles. I took it to the dealership for them to tell me my extended warranty doesn't cover it and to buy an aftermarket exhaust because it would be too expensive to replace it. I think they quoted me at $1200

Brake pedal gets hard and you will need to step on the brake hard in order to brake.

Twice now GM has recalled the block heater for my truck. The first remedy did not fix the issue and had to be recalled again. This was back in July 2021. It is now the end of November 2021 and nothing more has been done. My truck requires a block heater in order to start in the upcoming cold months. This will make two years in a row I cannot use my truck when the temperatures fall below freezing. It directly affects my livelihood because I need a truck for work. What more can I do to speed this process up? How is it GM can still sell new diesel pickups with working block heaters, but are not required to fix the older diesel pickups?

I was on highway 65 coming out of Rocklin Ca going back to Yuba City Ca. The Chvey Silverado with out any warning it just lost power and I had to pull over. I am glad I was on the slow lane. If I was on fast lane with a big rig behind me. It would have been bad. After pulling over the Eng Light when on for the first time since I have owned the truck. Not any time before. I thought if a family with children was in the fast lane and this happened it would not be a good out come. I had it towed to my home the chevy dealer was close. On July 18 I had it towed to the dealer I had the truck towed to Wheeler Chevrolet In Yuba City They replace the engine computer and the tranny computer . And to day Aug 1 , 2021 they said they would fix the tranny. I am wondering if they know what they are doing ? This is very disturbing I am very apprehensive about the safety of the truck if this were to happen again !!

The drivers seat moves while turning. It feels like the seat is sliding when turning then there is a "catch" and a sudden stop in movement. While driving and making a turn the feeling the seat will come unbolted from the floor is a unnerving feeling to say the least

Radiator developed a leak as described in General Motor's Service Bulletin PI1513F dated January, 2019. Safety was put at risk due to having a vehicle which could have a sudden radiator failure and permanently damage the vehicle. The Dealership I had my radiator replaced at would not state if they have had this issue occur often. No warning lamps or messages prior to the radiator losing 1.5 gallons of coolant. My first symptom was the engine overheating.

3 of the 4 tires on this particular vehicle (ALL 3 HAD SAME DOT#) had APEX SEPARATION @ the bead. 4th tire was removed for having the same DOT as the 3 failing tires. The tire size is LT265/60R20 FALKEN WILDPEAK H/T02 HD. Tires were installed on 12/17/2020 and the incident occured in June 2021 @ 11,500 tire miles.

While driving or idling Transmission temp was around and staying at 240.

Consistent failure with AC condensor for 2014 thru 2019 Chevrolet trucks. So common, should have been fixed or replaced.

The trailer brake control module stopped working on the interstate while pulling a 37' fifth wheel camper. This defective part caused the truck to not have any electric brakes on the camper. A warning message appeared on the dash. A new trailer brake control module fixed the problem. Since the vehicle was out of warranty (37,878 miles) the part was not covered by the dealer. The dealership where the part was purchased informed me that it was a common problem. This problem occurred while traveling at 65 miles per hour. There was only the truck brakes to stop the camper without the trailer brakes working. This is a serious problem and should be addressed.
