“Its a brand new pickup track when I got it after one year a issue came up with caramel looks like leaking under the truck, radiator coolant got mix with engine oil. No warning light , engine might overheat or engine might lockup. The dealer replaced the radiator and just flush the line. I heard so many complaint about this issue. But never heard any recalled.”
NHTSA complaint #11306902, filed 2020-02, 10,500 miles“Starter is bad, drags when cold or its drawn the battery down to where it won't start. Jumped it once, the dealership replaced the battery but that 650 cold cranking amp is not big enough for the starter. We need to go to a 1000 cold cranking amp plus a 200 amp alternator. Or we could just replace the starter with a good one.”
NHTSA complaint #11287705, filed 2019-12, 24,592 miles“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. …”
NHTSA complaint #11364563, filed 2020-10, 38,990 miles“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. …”
NHTSA complaint #11364076, filed 2020-10, 19,934 miles“Bulletin no pi1513f describes an issue with chevy silverados (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. …”
