2015 Chevrolet Tahoe

On November 20, 2018, the Office of Defects Investigations (ODI) opened PE18-012 to investigate instances of sudden onset of a hard brake pedal that could result in extended stopping distance due to an issue with the brake assist vacuum pump in model year (MY) 2014 through 2016 GMC Sierra 1500 and Chevrolet Silverado 1500 series pickup trucks and MY 2015 through 2016 Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe, and GMC Yukon SUVs.If the brake assist vacuum pump fails to operate as intended, the amount of brake power assist supplied to the driver can be significantly reduced, extending the subject vehicle stopping distance. GM stated that the root cause of pump failures was due to foreign debris such as oil sludge in the engine oil. GM stated that this debris can become trapped by the oil inlet filter screen. Under normal operation, this screen allows a small amount of oil into the brake vacuum pump. The foreign debris can, over time, clog the pump which can cause a loss of lubrication and a reduction in the amount of vacuum produced leading to a hard pedal and extended stopping distance.On December 13, 2018, GM issued a Special Coverage (N182202780) for the brake vacuum pump issue in MY 2014-2017 trucks and 2015-2017 SUVs on the K2XX platform for 6 years or 72,000 miles. Special Coverage repair includes the replacement of the vacuum pump and vacuum pump belt. Consumers received notification of the coverage via mail. On September 6, 2019, GM notified NHTSA that it was conducting safety recall 19V-645 which reprograms the electronic brake control module (EBCM) and included approximately 3.5 million trucks and SUVs. In October 2019, GM extended the terms of special coverage N182202780 to 10 years or 150,000 miles as well as now including the entire scope of recall 19V-645. In October 2020, GM expanded the scope of coverage N182202780 to include the MY 2018 Escalade and 2019 Tahoe.The remedy implemented in GM recall 19V-645 appears to be sufficient in addressing the safety-related concerns of this issue. Loss of vacuum assist now occurs at a progressive rate as well as there being a more timely warning of a brake problem to the driver through the driver information center (DIC). In view of the recall action and revision to the special coverage, this Preliminary Evaluation is closed. The agency reserves the right to take additional action if warranted by new circumstances. The ODI reports cited above are available for review online at NHTSA.gov under the identification numbers in the attached document.

I purchased this car previously owned. As I’ve had to drive it everyday. I notice the tires/wheels when turning left or right, when parking …the wheels tend to lock then I must put in muscle to turn and return to a straight position. This has gotten worse to the point I almost ended up on a curb last week. Someone needs to check this vehicle because something is wrong. I keep impuestos with the maintenance but this locking of tires/wheels and then the constant shudder afterwards is dangerous. I’m appalled there is no recall or at the very least a free diagnostic or inspection at a dealer. I already told my family to sue if I die or get hurt in this Tahoe. Totally unacceptable

Incident

May 25, 2026

The contact owned a 2015 Chevrolet Tahoe and stated that while driving, the vehicle's doors locked and unlocked randomly, the cabin lights flickered, and the doors failed to unlock properly during entry attempts, while the radio randomly selected its own options and the touchscreen occasionally stopped working despite the alternator and battery being replaced. Furthermore, the vehicle suddenly and randomly lost motive power and shut off on main roads, highways, and at stop signs, which caused the dashboard to flash on and off and the power steering to fail completely. When attempting to turn off the vehicle by twisting the key, it refused to shut down initially and triggered a large engine bay fan to kick on, though replacing the temperature gauges eventually resolved this specific shutdown issue. The vehicle has been taken to multiple dealers and independent mechanics, but was failed to be diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 250,000.

While driving, the vehicle experienced a total loss of power steering, accompanied by a 'Power Steering: Drive with Care' dashboard alert. The steering wheel became extremely heavy and difficult to maneuver. Simultaneously, the ABS and brake warning lights illuminated. Although I managed to bring the vehicle to a safe stop, a subsequent repair attempt failed to resolve the issue. The vehicle remains undriveable as the intermittent failure persists, creating a severe safety hazard.

The park assist enabled flashed and when I brake it studders or I have to slam on my brakes because my car won’t stop. I see this is a recall on other tahoes but not mine!

I am having power steering issues. I reached out to Chevrolet and they said in their system the recall was performed in 2019 prior to me purchasing the vehicle in 2021. I should not have to pay for an issue that was recalled. I’m unaware of what was done prior to my purchase of the vehicle in 2021
