First my engine light came on and as I was in my way to the dealership I lost my brakes. It stayed at the shop for a week before I was contacted only for them to tell me that there was metal shaving in my engine oil and they recommend full replacement, meanwhile haven-??t even made it to my brakes. GM offered me 3K toward replacing the 13K+ engine. That-??s so unacceptable!

- Desoto, TX, USA

I am reporting a safety concern that I believe should be included in an existing or expanded recall for the Chevrolet Silverado. The issue involves engine replacement due to metal shaving being found in oil & brake failure, which occurred on 05/01/2025 The problem with the brakes occurred while I was in heavy traffic in Dallas, Texas multiple times, resulted in multiple near-accident experiences that day. The truck has been diagnosed by a mechanic, at the Chevy dealership and I believe this defect poses a serious safety risk and may be affecting other Silverado vehicles outside the current recall scope. I have driven the vehicle to Chevy and stayed in constant contact with the dealership, had diagnostics done, but the issue has not been resolved. am requesting that the NHTSA investigate whether this issue warrants inclusion in the current recall or a new safety campaign. I have on had this vehicle less than 2 years and I put less than 70K miles on it. I purchased it from vandergriff Chevrolet in Arlington,

Metal shavings were found in my oil after the check engine light came on a day before I took it in. The day that I took it in my brakes limited the speed of my truck to 43 mph due brake malfunction. The dealership called and told me that they recommend engine replacement due to the metal shavings found in the oil. I can give more in depth info as I receive it but I just wanted to alert Chevy that my vehicle is doing the same thing that the others are getting recalled for.

When putting vehicle in PARK and releasing the foot brake it rolls back an excessive amount of space sometimes it rolls back so much we begin to get scared thinking we are still in DRIVE and jump back in vehicle just to learn we are in PARK. We have had this issue since the day of getting truck in August of 2024 and how much it rolls back is never consistent on the length of the roll back. Sometimes it feels like it make even slip out of gear and just keeping rolling. It-??s very scary and we have almost knocked ourselves out when it happens trying to jump back in to stop it.

Mechanics said that they see this on all new chevy trucks that the bracket causes the rubber brake line to rub on the bracket holding it in place also causing it to stretch and tear. Resulting in a over 500 dollar fix. The brakes failed on the interstate causing them to lock up. Almost killing me and my daughter but was able to gain control of the vehicle and save it.

While leaving work I started the truck like normal and the dash lit up like a Christmas tree. Saying service ESC, service power steering, and service brake system. The ESC light was on as well as the check engine light. There was no forewarning about this.

- Phenix City, AL, USA

I took my car to the dealership four times because the engine light and the ESC light kept coming on. It kept saying there was a misfire so they changed the spark plugs and did a gas treatment after I left the dealership the light came back on so I returned the next day. They change one wire that-??s what they told me. The problem was so I left engine light came back on. I returned the next day then they changed the wires I left the facility again. The next day I got them started the car, the same problem, engine light, and the ESC light and now they have the car in the shop and they need to break the engine down to see what-??s causing the misfire and to find out if I need a new engine or not. Who is all that sh*t right now?

I was driving along about 45 mph and the truck was cruising in overdrive so about 1500 rmp on tachometer. I hit the gas to climb a hill as truck started to lose speed and when it tried to shift out of od to pick up speed the brakes seemed to slam on and I skidded to almost a stop. This has happened several times when climbing a hill or anytime I have to pass a vehicle or accelerate from out of overdrive. The dealer could never seem to get it to reproduce during test drive. They recently said there is a service bulletin for this exact issue and are waiting for a new valve body for transmission. My service records show I had a new valve body installed last year due to transmission pump bearing coming apart internally. The valve body is only a year old. But this is a very dangerous situation. I have to drive my truck for work and I have to be really cognizant of how hard I touch the gas and what gear I am in. If this happens to anyone while on the freeway and a semi or another vehicle is too close their truck will downshift and lock brakes and it could cost a life. It only happens under these circumstances but it has to be a recall. A service bulletin doesn't get it as someone has to have it happen for it to even be looked at. I have to drive my truck as I do not have a choice. But a service bulletin shows that GM I'd aware of the issue but they are unwilling to do a recall. A lotnof silverados are on the road and inwould hate for anything to happen. It could ruin a lot of lives.

Started having a rubbing sound in rear end of vehicle. Took it to dealer. Brake calipers are a issue on this model and dealer says, -?? found updated rear brake calipers with deflectors to help with dirt in rear calipers/not covered under warranty customer pay expense-??, they are replacing rotors under warranty that got worn out. They want me to pay $2400 to purchase and have the -??updated brake calipers-?? installed. If brake calipers are updated then that means there is a known issue with them. Spoke with the manufacturer and they said too bad.

While parked I turned on the truck and got service sec warning and power steering failure. Brakes barely worked and wheel was locked. After restarting the car three times it went away and truck became driveable. Took it to a dealership and they said there-??s nothing they could do as a code didn-??t pop. Seems unacceptable as my family is consistently in the car and if it happens while driving could be extremely dangerous

While pulling out into traffic the vehicle will momentarily lose all electrical power and the engine shuts off causing loss of brakes and steering.

Loud growling. Breaks safety concern due to fail.

- Plattsburg, MO, USA

My safety system service warning comes on for about 30 seconds and then goes back off. This has happened about 4 times now. The transmission causes my truck to shake randomly. My pulley is going out and the local dealer said they wouldn't replace is under warranty(even though my warranty was still is effect) because they said it looked like someone sprayed tire cleaner under the hood(I bought it from the same dealership that I took it to for this service.) The brake seem to shake already when coming to a stop. They seem as if they are wearing prematurely.

ESC failed. The 2021 Chevy Silverado (39495 mi) began to shutter and a slight bouncing of the rear end. The ESC light came on the service ESC warning on the dashboard then the check engine light began to blink at the same time the parking brake light came on. The dash warning switched to have parking brake serviced. The truck as best as I could tell applied the parking brake several times for no reason while at highway speeds and traffic on all sides. All warnings stopped when Auto engine shut down at exit ramp light. Previously brought into dealership for -??Service ECS-?? and -??Service Power Steering Drive With Care-??. I was told -?? unable to replicate -?? (23194 mi). Vehicle was returned to me. They did confirm the dash warning was stored in the computer. I do not believe any warning (blinkers) or brake lights came on to warn vehicles behind me of the rear brakes being applied by the ESC.

So I have been having issues with my truck losing oil. My dealership told me that Walmart made an issue with the oil filter causing it to leak oil out. After the dealership corrected the issue. I was on my way to the store this morning it was damp so I was having a lot of traction issues. Got to the gas station checked tires, no issue with them. Temperature is above freezing. Just thought maybe it-??s in my head. Well I get about 2 miles from my house and low oil light comes on again. So this is an issue. It has happened 2 times to me. Had I not been cautious I could have slipped off the road or had a collision because the oil mixing with the water on the roadways. I will be reaching out to my dealership tomorrow to try and get them to correct this issue again. Seems there is a service bulletin on how to tighten the oil filter. Because of oil leaks.

Anytime the weather gets colder than 32degrees Fahrenheit the DEF system freezes, which even if the tank is full makes the truck go into limp mode until it thaws out. The engine light pops on and off with no codes associated with it. Now the breaks and break lines are freezing when it gets below freezing. These are just a few of the reoccurring problems we-??ve experienced since buying the truck less than a year ago.

2021 Silverado Trail Boss. Went to the store, came outside started the truck and it showed me ESC Warning and Power Steering Failure Drive with Care notice on the dash. The Steering was very hard to turn. I tried multiple times, and it did not work. I started reading information on line and found out that there are multiple truck owners who had same issue. I saw some information to leave the truck off for 20 - 30 min and try again. I left it off for 30 min and started again. At that time it started fine. I am going to the Chevy dealer because this can also happen while I am driving and it can cause an accident. My truck has only 12k miles.
