General Motors LLC (GM) is recalling certain 2018 Cadillac Escalade, Chevrolet Silverado 1500 and Tahoe, GMC Sierra 1500 and Yukon vehicles equipped with either a 5.3L or 6.2L V8 engine. The output of the mechanical vacuum pump can decrease over time, decreasing the amount of vacuum/power brake assist.
A decrease in brake assist can increase the brake pedal effort and distance required to stop the vehicle, increasing the risk of a crash.
GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began November 11, 2020. Owners may contact GM customer service at 1-866-522-9559, Cadillac customer service at 1-800-458-8006 or Chevrolet customer service at 1-800-630-2438. GM's number for this recall is N202300860.

Service brakes, hydraulic, antilock/traction control/electronic limited slip, wheel speed sensor/tone ringOct 24, 2019
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.
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.
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.

Representative owner complaints: forward collision avoidance
4 reports, newest first. Show all
Visibility, Forward collision avoidance, Oct 8, 2025
The contact owns a 2018 Chevrolet Tahoe. The contact stated that in 2024 the front windshield was damaged, and the windshield was replaced. The Insurance Company was notified and requested that an aftermarket windshield be placed on the vehicle. In May of 2025 the contact noticed that the Chevrolet Assist Camera behind the rearview mirror had failed. The vehicle was taken to the dealer, who determined that since the windshield was not an OEM windshield replacement, the part caused the camera to fail. The camera was unable to be calibrated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 82,000.

Caliper became stuck which produced smoke coming from tire. Had the caliper replaced. Then months later my forward collision system activated because a car in front of me stopped abruptly. After the car automatically braked to slow my car down, the brake never released and became stuck and the ABS light came on. Replace the abs sensor and two days later the brake engaged on its own while doing 60 mph on the highway. Now whenever the hill assist, collision warning, or anything else is activated, the brake engages and gets stuck. In addition, at times on the highway my brake will engage on its own.

While driving home, the the FAC, forward automatic crash, indicator light came on, I applied the brakes and watched to my dismay as my vehicle slowed down but would not stop. I applied steady hard pressure until impact with another vehicle in front of me. The FAB, forward automatic braking system never kicked in. I will contact the dealer concerning the above issue.

My vehicle recently has had 2 issues that I have taken in to the Service Shop for 3 times and the problem has not been fixed. My most concerning issue is my brakes. My brakes are doing the exact problem indicated in this article: https://www.consumerreports.org/car-recalls-defects/gm-recalls-suvs-and-pickups-for-braking-issue/ When the brakes malfunction, I feel a vibrating brake pedal, feels like my vehicle is not going to stop on time, I hear a ticking noise from the engine and my Brake Assist Service light comes on. The issue continues until I can pull over and restart the vehicle. It is a very uneasy feeling having to drive a vehicle that you do not feel safe in. I called 800 Chevrolet's Customer Service number provided in the article and they are unaware of the recall mentioned in this article. I do not know where to go from here. I just want my vehicle fixed and to feel safe. My 2nd issue is regarding my Adaptive Cruise Control. I've had it in the shop 3 times for this also and they did replace a part but that did not fix this issue. I will be driving down the highway or interstate and out of the blue my alarm starts dinging, the seat vibrates, the cruise control gets kicked off and I get an alert on my dash stating that the Adaptive Cruise Control was disabled. Each time it has happened to me there is nothing around but it immediately starts reducing my speed. If someone were behind me it could cause a crash because of the unexpected speed limit reduction. When you go in to look at recalls on 2018 Chevrolet Tahoes it shoes that there is 3 of them that have been issued, yet my VIN is not included in any of them? What can I do from here? I've called Chevrolet's 800 # and they created a "High Urgency Case" but I have not heard back. Attached are my copies of service records and vehicle summary showing there has never been recalls on my VIN #.
