Service Brakes 6

“I own a 2020 Tahoe, 160,000 miles. While driving, the vehicle experienced a sudden loss of brake assist due to a failure of the vacuum brake pump. The brake pedal became extremely hard, and the vehicle would not slow or stop as expected, requiring me to put vehicle in neutral and frantically find a way to the shoulder to force a stop (pulling the emergency brake). This created a dangerous condition and significantly increased stopping distance, posing a serious safety risk to myself, and others on the road. There was little to no warning prior to the failure. This issue appears to be consis…”

“Tahoe transmission failed with 103,000 miles… took to Chevrolet they confirmed, took to a transmission specialist they confirmed failure but they said the computer was throwing weird codes and they believe this has a factor in transmission issue. On the way home the brake system alert went off and the car would not go above 35 miles an hour … I get this is a safety feature but it was dangerous in the location this occurred ans this car was not that old and does not have high miles to justify this type of issues”
NHTSA complaint #11737487, 2025

“While driving toward intersection, light changed to red. Applied pressure to brake pedal and pedal became extremely difficult to press. Vehicle was not slowing as expected with pedal pressure becoming very hard to press to slow vehicle. Warning on dash "Brake Assist" and Chevrolet app displays "Antilock Braking System" and text that states Schedule service now. If my wife would have been driving, this would have caused an accident. This is extremely dangerous condition that must be addressed with a corrective action taken by the manufacturer.”

“When I make turns/curves my Tahoe will periodically lock the wheels on the opposite side and pull our vehicle to the other lane of travel. I’ve noticed previous recalls on other Tahoes for the same thing and the delearship claims they can’t replicate the problem and our vehicle is not included in that recall. I have had the vehicle in Auto and 2wd and it continues to happen. I can disengage the 2wd to auto and vice versa and it sometimes feels to help the problem. I have also disengaged traction control and that will seem to help as well. This has been happening on and off for over a year.”

Fuel/Propulsion System 3

“Driving long distance from Florida to New York and in VA, experienced a check engine light after fueling. Vehicle started, stalled and trembling excessively. It was taken to the Chevrolet dealership across from the gas station (total luck).

“Check engine light illuminated then went off and came back on after another drive cycle. Vehicle began to idle rough and experienced hard shifting and acceleration hesitation. I checked the oil and noticed a fuel odor smell on the dip stick and the oil appeared thin. Upon mechanic inspection they found a malfunctioning high pressure fuel pump. This part was recalled on other vehicles of the same model year due to bad welds. This could have resulted in fire if left unchecked.”

“My engine light keeps coming on randomly. When this occurs, the dashboard lights blinks and I get a " steering assist" error message. Once this happens it is really hard for me to steer AND I lose acceleration as well. Imagine losing acceleration in the middle of an intersection. Also, I noticed my temperature gauge moves up & down as well. I have taken it to the dealership each time it happens and they are saying they haven't been able to replicate the issue. The engine light only stays on for a few hours or days and the problem goes away once the engine light is off. From my research, this…”
