It will also prevent you from entering the vehicle without a second set of keys or other methods of unlocking the door (onstar, locksmith). This could put occupants in danger and exposed to the elements unexpectedly and also place inside children in danger. Diagnosis - Keyfob - If battery in keyfob is low, the programming of the vehicle is set to automatically lock even if vehicle is in the ignition and running. when unlocking vehicle with the defective fob, vehicle will unlock, then immediately lock preventing entry. Remedy - Replace battery in key fob and truck works as normal. | Crash: No Fire: No | Unknown |
| May 2025 | ENGINE | On 4/18/25 I was driving to work and was about 2 miles from work when I started to get all kinds of faults displaying on my screen. The engine started to run rough; it sounded like it was not running on all cylinders. After work I drove it straight to the maintenance shop I have been using. They informed me that a lifter failed and went into the cam shaft and created all kinds of metal. I was informed that this was the second Chevrolet Silverado they have had this problem and replaced the engine. | Crash: No Fire: No | Unknown |
| May 2025 | AIR BAGS,FORWARD COLLISION AVOIDANCE | The airbag module is not connecting to the rest of the modules. There is a recall on this module in other VINs but not mine. | Crash: No Fire: No | Unknown |
| May 2025 | POWER TRAIN,SERVICE BRAKES | Brakes sometimes require more pressure to stop or slow down. Transmission shutters and makes a clunking noise between shifting points. Kind of a sound bad u-joints make. Air Conditioning leaked all freon out in 2024 with 70k miles just 2mos. after service at a GM Dealership. Still not repaired. | Crash: No Fire: No | Unknown |
| May 2025 | SUSPENSION,ENGINE | Both upper control arms have broken off at the ball joints. Also the cam and Lifters are failing and this vehicle has been maintained in accordance with the manufacturer guidelines. | Crash: No Fire: No | Unknown |
| May 2025 | POWER TRAIN,ENGINE | My vehicle has had transmission and engine problems that should not have been an issue until after at least 100,000 miles. At 11,577 miles I reported hard down shifting as well as a hard shift / kick when going from reverse to drive when the transmission would feel like it would slip and then kick when shifting from 1st to 2nd gear on automatic transmission. There were no codes and dealership said they couldn't duplicate problem. At 58517 miles the service 4x4 warning light came on as well as a shifting problem was continuing. A transmission valve body was replaced and a transmission service / fluid replacement was done under warranty or extended warranty. The shifting problem has continued. It has come to my understanding that Chevrolet put out a bulletin about changing the transmission fluid should solve the problem and to tell customers that some hard shift could be normal and not a problem. And I have heard about some class action lawsuits that have been filed. A second and more major issue was the 5.3 liter engine failure that occured at 62,093 miles after having a tapping noise develop and some loss of power. But this issue began earlier at 40,125 miles when I had a fuel injection clean due to it running rough. Extended warranty replaced engine with a used motor and I was still charged $1158.93 for amounts extended warranty didn't cover. My Son's 2015 Silverado 1500 which I owned previously had to have the transmission rebuilt for just under $5,000 just out of extended or manufacturer's warranty. We don't pay $60,000-$70,000 to have engines and transmission fail before 100,000 miles and before the loans on vehicles are paid off. We shouldn't have to be paying a loan on a vehicle we can't even drive because it is in the shop for an extended period of time. At 62,298 miles after getting the truck back from the engine failure, the starter then failed and was replaced under extended warranty with $133.76 cost going to me. | Crash: No Fire: No | Unknown |
| May 2025 | POWER TRAIN,ELECTRICAL SYSTEM | The truck started shuttering one day it was like I was driving on the drunk bumps but I wasn't. Also it will drop gears when it shouldn't and at times it will kinda jump like it's losing power and don't want to go. I have taken it to my step dad who has been a transmission mechanic all his life and he said the transmission needs to be rebuilt but even rebuilding it won't solve the problem because it is a flaw in the way it was made so rebuilding it they use the same parts and everything so it will eventually do the same thing again it's all just a matter of when. He also had me go to another really good transmission guy and he said that we could replace the torch converter but still may need a rebuild l. I don't know if any that has to do with my passenger tire wear or my wheel bearing coming loose while driving only one bolt was holding it on when my husband checked it. The wheel bearing coming loose is pretty big safety problem. As for the transmission my step dad works at a transmission shop and he said they get probably 3 to 5 trucks a week having the same problem mine is having and I know they have been recalls on other trucks that have the same problem as mine just my one wasn't in the batch they recalled . | Crash: No Fire: No | Unknown |

| May 2025 | POWER TRAIN,SERVICE BRAKES | Sometimes when traveling higher speeds (55-70)and braking going downhill, a hard brake will come out of nowhere. Not enough lock up the brakes or anything but enough to scare the crap out of you!!! If it would happen to a elderly person or a less experienced driver, they could probably lose control or wrack. With the power train...sometimes when accelerating(from a stop or low speed)it seems as though it gets stuck in gear or skips a gear.

| May 2025 | SUSPENSION | Passenger side Upper control arm broke in two about to re-enter I75. Had been on I 75 and was going back on it when handling went wonky on Service road. You can see from the rust in the break this stamped part was cracked a while. Vehicle has not hit or run over anything since I have owned it. Had I been on I75 at highway speed it would have been deadly. | Crash: No Fire: No | Unknown |

| May 2025 | ENGINE | In May 2023, my 2018 Chevrolet Silverado 1500 with the 6.2L V8 engine experienced a catastrophic engine failure at 82,986 miles. The failure involved the camshaft, lifters, oil pump, and other internal components. I paid $7,319.63 out of pocket to have the engine disassembled and repaired by a certified mechanic. I recently learned GM issued a recall (NHTSA Recall No. 24V266) for 2021–2024 vehicles with the same engine due to internal engine failures caused by crankshaft and rod bearing defects. Although my 2018 model isn’t included, the failure I experienced closely mirrors the conditions cited in that recall. I believe the same defect may exist in earlier models like mine. I’m submitting this complaint to urge NHTSA to consider whether the recall should be expanded to include additional affected years. | Crash: No Fire: No | Unknown |
| May 2025 | ENGINE | This 2108 vehicle had 56174 miles on it in October 2023 when the starter went bad, then with 56382 miles on it in November 2023 the lifter failed and the engine had to be replaced and then with on 56838 miles on it in Dec 2023 the engine light came on and the dealership replaced the canister and solenoid. All in a 3 month time. Chevy says it happens. Then we start reading it is a problem with their 2019 to 2024 vehicles. Maybe it goes back more. | Crash: No Fire: No | Unknown |

| Apr 2025 | ENGINE | I well maintained my 2018 Chevrolet Silverado, and now the motoer is failing, loss of power and just started smoking from exhaust, my mechanic said that the motor is in the process of blowing up. I made every oil change, and maintained the vehicle because I wanted it to last and be the last vehicle I had to purchase.

| Apr 2025 | ENGINE | An independent service center confirmed that the water pump failed and fell apart. This water pump is a 4-groove pulley (part number 12685259) specific to my vehicle. Most other Silverados have a 6-groove pulley system. This 4-groove pulley water pump is unavailable from the dealer or any of the part stores, as they are on back order with no resolution or availability date. GM has notified some parts stores that this part has been discontinued and is no longer available. This truck is less than 10 years old. There are no other parts, either aftermarket or otherwise, to replace my water pump. The water pump is a vital engine component needed to prevent significant engine damage, and without it, the truck can not run independently without overheating. It is essentially the heart of the automotive cooling system, because the truck water pump function is to continuously circulate the engine coolant from the radiator to the engine and back to the radiator. I have had my truck in an independent service center since January 2025, waiting for this part, which is unavailable. I do have the original part at the shop available for inspection. There were no warning lamps, messages, or other symptoms of the problem before the failure; it just started making a clanking sound, and I immediately took it to a shop, and have been out of a vehicle for 5 months. | Crash: No Fire: No | Unknown |
