Recalls and investigations

2 recalls on the brakes cover the 2015 model year. A recall on the same system isn't always the same failure, so read the defect text.

19V-761Oct 24, 2019
Service Brakes, Hydraulic:Antilock/Traction Control/Electronic Limited Slip:Wheel Speed Sensor/Tone Ring

General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.

Risk and remedy
Risk: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.
19V-645Sep 6, 2019
Service Brakes, Hydraulic:Power Assist:Vacuum

General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.

Risk and remedy
Risk: As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192268490.

NHTSA investigations into the brakes on the Tahoe

Brakes · model years 2015 to 2016

Brake vacuum pump failure. Closed apr 10, 2022, led to recall 19V-645.

NHTSA summary
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 w

What owners wrote

““Trailer Break System” warning keeps popping and makes it very difficult to drive safely!”

Filed Feb 7, 2022

“The trailer brake system alert is going off twice in a row every 45 seconds to one minute. The chiming is highly distracting while driving and seems to be a wiring issue.”

Filed Dec 31, 2021

“Brake assist problems. When stopping/slow braking while being in heavy traffic, or drive thru, the brakes will vibrate and will not come to a complete stop without it rolling, almost into another vehicle. The brake petal will be stiff and the vehicle will continue to roll. This happens a lot, but seems to only happen during stop/start, bumper to bumper situations.”

“I bought the tahoe from a buy here pay here Its a salvage car from the action The guy who sold it to me said he would fix and never did I took it in to a shop because i almost recked and the transmission i think messed up because of the brakes and steering There is also another car he sold that my friend bought for me to fix because the guy sold it with out airbags”

Should you keep driving it?

This page can't tell you that. 16 of 196 reports involved a crash and 5 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
