Brake boost vacuum pump failure. While approaching a traffic light that was red, I applied the brakes. The pedal was very hard to press and required me using both feet to bring the vehicle to a stop. Stopping distance was much longer than normal. I removed the vacuum pump and found it had seized and broke apart.

The contact owns a 2025 Chevrolet Equinox. The contact stated that while driving approximately 15 MPH or below and coming to a stop, the brake pedal was depressed, but the vehicle failed to respond as intended, and the brake pedal was pumped several times until the vehicle responded. The contact stated that the failure mostly occurred while driving on wet, gravel, and snowy roadways. The contact stated that on one occasion the vehicle drove through an intersection. The vehicle was taken to a dealer twice; however, the failure was not reproduced on the first visit. During the second visit, the contact was informed that the failure might be related to a cruise control recall, and a software update was completed; however, the failure persisted. The failure mileage was approximately 2,000.

While coming to a stop, a snap ring came off the brake master cylinder. Vehicle top speed was 40mph, with the parking brake automatically engaged. ***Note from mechanic: Vehicle has several brake faults, C05CC and C05CF master cylinder piston position sensor performance, C2A17 hydraulic brake sponginess, and C0277 brake pedal position sensor fault. Tech recommends Hydraulic Brake Unit replacement***

We changed the external fuel pump, we changed the oil cap to the vented oil cap, We changed the oil 2x within 2 days, once trying to get it by until we could get the new fuel pump on,and once directly after and still had issues. Losing power and getting stranded while trying to cross a busy highway is terrifying, 100% —it is an extreme, life-threatening safety risk.I returned the vehicle and took a heavy financial loss, The fact that this dangerous car is back with a seller means someone else is going to buy it, This report could prevent a fatal accident. We have seen multiple of these same vehicles all over places like facebook marketplace and on the side of the road. They are dangerous vehicles and I've heard multiple accounts in which even your dealerships dont know how to fix it. I believe you have a responsibility to consumers to pull these cars from use and make it right to all who have not gotten what they paid you for buying this car from you.

The contact owns a 2025 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, there was an abnormal odor inside the vehicle.

Additionally, the steering wheel was jerking while the lane assist feature was activated; however, the vehicle was not veering to the left or right side of the lane. No warning light was illuminated.

The vehicle was repaired; however, while the contact's husband was driving at an undisclosed speed, there was an abnormal sound coming from the vehicle. The driver pulled over to the shoulder of the road, and after selecting the 2WD feature, the 4WD feature was disengaging, even though the 4WD warning light was not illuminated.

The vehicle will not allow the truck to be turned off everytime, it states the truck must be in park to be turned off, and the truck is in park. The engine lost power and staleld twice, and loses accelerator power multiple times. The transmission has dis-engaged 3 times. All of this since July 2026. The truck has 54,000 miles on it.

While driving my 2020 Chevrolet Colorado through [XXX], the truck began having difficulty accelerating. As I exited the highway and turned into a gas station, the truck suddenly lost power. The steering became extremely difficult, and I lost normal brake assist. The brake pedal became extremely hard, and I had to apply extreme force to stop the truck and avoid crashing into a wall at the gas station. Fortunately, no collision occurred. The truck was towed to Ed Corley Ford in [XXX] because I was stranded in a remote area with very limited options. They diagnosed a failed/broken vacuum pump and told me replacing it should make the truck operable so I could drive it home to [XXX]. I authorized the repair. After replacing the vacuum pump, they told me they started the truck and heard an abnormal sound. They shut it off, and when they tried to restart it, the truck would not start. They wanted to perform additional diagnosis, but I declined and had the truck transported back to [XXX] for evaluation by a Chevrolet dealership. Huffines Chevrolet Lewisville inspected the truck. Their technician removed the camshaft position sensor and used a borescope to inspect the camshaft. They documented that the camshaft is damaged at the end where it connects to the vacuum pump and stated the actuator pin was most likely bent due to the vacuum-pump failure, damaging the camshaft and causing it to be slightly out of time. I have also been informed of engine damage. The truck remains inoperable and is currently available for inspection. I am concerned this is a safety defect because the vacuum-pump failure resulted in a sudden loss of normal brake assist while I was driving and was followed by camshaft/engine damage. I am asking NHTSA to investigate this failure and similar Chevrolet Colorado complaints. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
