I have a 2018 Chevy Silverado 1500 that I bought in June of 2018, brand new from integrity Chevy in Chattanooga tn.. One ago ago I was driving home and the check engine light came in and starting running poorly and you could hear a knocking noise coming from the engine. I took it back to integrity Chevrolet in Chattanooga, the employee at the auto service counter got inside and started the truck and he new at once what the issue was, he didn-€™t even take it back to the shop so the mechanic could look at it. He told me it was the lifters knocking. I left the truck with them. The next day he called me and told that the lifters where bad and had bent push rods. They had to replace everything on both sides, told me how much it would cost. It was out of warranty as I had 74,000 miles on it. The total cost that I had to pay was $5,468 dollars. The truck is less then 4 years old. The employee at the desk when I paid for it said that I just paid for a new engine! Again the truck was less then 4 years old.

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.

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"

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

Bulletin no pi1513F describes an issue with Chevy Silverado (amongst other models) and the radiators leaking due to over cycling of the thermostat. I have a 2018 that is barely 2 years old, and a leaking radiator! GM is doing nothing to own up to this issue, and they are expecting me to pay the entirety for a replacement, and I don't even have confidence it won't happen again. This bulletin should be extended to cover all years until GM proves they have a solution in place. It is completely unethical for GM to not address this issue and expect me to put this much money into a brand new truck. I slowly began to notice the coolant reservoir going down. I eventually brought it to my dealership (twice), and on the second visit they found the leak, although mileage was over the bumper to bumper warranty during the second visit. It is a very slow leak.

Coolant water keeps spilling from water pump. As I was driving on the freeway, the pump blew and spilled all the coolant and had to pull over to the side. Had to get it replaced paid $150 for the part and than labor another $150. Truck has less than 30K miles and the water pump already breaking down. New vehicles are now designed to break on you easily so us customers spend more on parts and labor.

I started my vehicle and put the truck in reverse to back out of a parking spot. Gave the truck gas and it wouldn't accelerate. Put the truck back in park and looked at the guages and there were no RPM's showing on the cluster and the oil pressure was at zero. There was a message that said trailer brake system on the screen. I turned the truck off and on again and the same thing happened. I put the truck in drive and it would move forward but the motor ran very rough and there was no power steering. I dismissed the first message and another message popped up that said "steering assist is reduced, drive with care." I pulled into another parking spot, turned the truck off, and waited for a ride. I started the truck when my ride showed up to make sure it was still not working and it was as if nothing happened before. The truck had no issues on the 16 mile drive home. Got home and turned the truck off and started it again and the message came back up and the issues came back. I have a video of the trailer brake system and me shifting the truck and the guage cluster. I have a picture of the steering assist message.

Truck will lose all power, everything will shut off, and then come right back on. It has happened while accelerating into traffic, slowing down turning right and turning left, and while moving straight ahead. It has been in the shop once for this same issue and they tell me they cannot find anything wrong with it. The stabilitrac warning will come on and go off and have had stall warning flash in traffic at stop lights. This has been going on for the last 12,000 miles and I have 20,083 miles on truck now. The clock and radio reset. It shutdown pulling into traffic on a busy highway and was a very dangerous situation. Been trying to get it into dealership since 3 weeks ago and no luck. This is not the only issues with this truck.

While driving on interstate towing empty 12' trailer, the engine stopped and received stabilitrack message and transmission too hot. This happened again after letting engine cool down. Had the tramission fluid changed two days later. Dealer just stated their was a loss of communication with the engine. One week later received transmission hot, idle engine message on the interstate while hauling the same trailer with only a riding lawnmower. Pulled over for 30 minutes and drove the rest of the way home at a reduced speed. Highway speed was 70 mph until it overheated, then drove 50-55 mph to get to my destination trying not to let transmission temperature over 220.

  • 59,700 miles
The plastic radiator has cracked and is leaking coolant heavily. Truck still under powertrain warranty by GM is only offering to cover 20% of the $1,823 repair cost. I noticed it when stopped to get gas, the vehicle leaking approximately 1.5 gallons of coolant while stopped for approximately 3 minutes. This caused the vehicle to overheat and needed to add coolant just to drive to shop.
