2015 Chevrolet Suburban

The defect

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.

The 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.

The 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.

the brakes, the hydraulic brakes

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.

When coming to a stop or backing from my inclined driveway the foot brake requires a hard push because it seems to lock up. I couldn't stop when braking. The problem is recurring. It has not been inspected for this recurring problem and no lights or warning signal appears on the dashboard.

Fuel line leak caused by design flaw in which line plastic fuel feed line (GM part #84200271) is installed too close to the undercarriage, causing it to rub against the frame due to vibration and wear a pinhole. This is known by gm in service bulletin Service Bulletin 17-NA-304. This is a fuel leak, that can causes significant fire danger to people, property, and nature. Eventually putting first responders at risk. Also the environmental risk of continuous leaking fuel. Luckily, I could smell it before anything bad happened. But if GM knows about this issue, it’s big enough they should do something about it and so should the NHTSA.

When our new mechanic was checking over the car, he and his other mechanic both noticed that there was an increased brake pedal effort even though the brakes were in ok condition. Every time I’ve had the car serviced I have them check the brakes because they feel off. The car stops and the brakes check out with previous mechanics but something doesn’t feel right. Our new mechanic then gave me a recall bulletin from GM N192268490 and said he thinks our car is experiencing this issue. The recall was attached to our VIN when the mechanic pulled it up but when we called the dealer and checked the NHTSA website, my VIN number was apparently not part of the recall. I am writing to state that I …
