2023 Chevrolet Silverado 1500: grinding or squealing brakes

Filed Jun 8, 2026 · Engine, Transmission · TX

At approximately 24,000 miles the engine had catastrophic failure under normal street/highway driving conditions. The engine is the 6.2L V8. The issue began with a high pitch squeal or chirping sound and noticeable power loss. I parked the truck over night and then drove it to the dealer first thing the next morning. While on the way to the dealership, which was less than 20 miles away, the engine began having much bigger issues. A loud knocking noise was apparent and the rear end began locking up causing the tires to also lock up. Once at the dealership the engine completely failed and locked up. The engine did have the newly recommended 0W-40 oil installed prior to the failure.

The vehicle has been exhibiting occasional hard shifts over the last 2-3 months. Over the last 2-3 weeks the frequency has increased. While operating the vehicle at approximately 30 mph the rear wheels temporarily locked during one of these events while my wife was operating the vehicle. There was no indication that this was going to happen and no indication after the event. We took the vehicle to the dealership where they performed a diagnostic but found nothing wrong. In the week since picking up the vehicle I have been operating it. I experienced two occasions where upon trying to accelerate at approximately 30 mph there was a severe jolt that caused the traction control warning light to flash. This was under minor acceleration just to maintain speed when going uphill. There was no indication prior to the event and once it had concluded the lights went off. I also experienced an occurrence of the rear wheels locking temporarily. I was traveling at approximately 40 mph on flat ground and gently stepped on the accelerator to maintain my speed in traffic. The rear tires locked for 1-2 seconds to the point the tires were squealing and you could smell burning rubber. There was no indication prior to the event that it was coming. Given my necessary reaction I was unable to see if there were any indicators or warnings present. Following the event there were no indicators illuminated. Outside of these events the vehicle seems to operate normally. It runs well and generally shifts smooth. However, the rear wheels locking up unexpectedly presents an unacceptable hazard that is not resulting in any evidence that the dealer can use to troubleshoot.

We were driving our truck with our family on vacation. We were going slowly entering the parking lot to our hotel when a sudden loud grinding noise caused our truck to shudder and shake. We stopped and got out and didn’t see that we ran over anything. We started to proceed and the sound was the same. We parked in a stall and left the vehicle overnight. No check engine lights were on. No warnings at all. It was Memorial Day weekend 2023. There were no dealerships open where we were vacationing, 3 hours from home. Very inconvenient. Later when the dealer looked at it, the thrust bearing was bad and the engine was shot. Needed a full replacement at 10,600 miles.

At approximately 9k mi the engine performance (2.7L MAX Turbo) started to become intermittent. I always record the fuel milage, and always drive the same way, to/from work. NOTE: Displayed mpg calculates within 1% of actual. We can assume the driving habits are identical each time. While driving on the same tank of fuel for a week at a time: one day heading to work the indicated mpg might be 17 mpg. Driving home, about 10 minutes into the drive, it might increase 25 mpg. The following day it could be the same 17/25 mpg or it might be 25/17. The weather is somewhat dependent, whereas around = 3/4 to the floor. There is also no downshifting from the transmission whatsoever. To make the engine respond to change, the accelerator must be fully pressed to the floor, forcing the transmission into a lower gear and causing the engine to 'wake up'. When the mpg is above 20 or 21 mpg, (and temperatures >50F) the engine performs normally, where gradual accelerations to the pedal increase the engine speeds and down shift as expected. I have contacted GM through the 'MyCheverlot' app a couple of times, and have taken the truck to the dealer twice for this. Both times from the dealer it was stated that since the engine light was not on and no codes were stored, there was nothing that could be done. The dealer installed a software update and sent me on my way. Lastly, the 4WD is now making a grinding/rubbing noise, since the software update and overcomes the engine power while making turns from a stopped position. If no acceleration is applied, the truck will come to a rapid complete stop if rolling <10 mph. Truck is a LEMON!!
