1. WHILE DRIVING STEERING WHEEL WAS MAKING A CLICKING NOISE WHEN TURNING. DEALER REPLACED UPPER STEERING COLUMN BEARING AND TURN SIGNAL. THREE MONTHS LATER DEALER REPLACED STEERING COLUMN AGAIN DUE TO SAME ISSUE. 2. ONE MONTH LATER BOTH FRONT COIL SPRINGS WERE REPLACED. 3. WHEN REPLACED SPRINGS, DEALER FOUND THAT LEFT FRONT UPPER BALL JOINT WAS LOOSE SO REPLACED UPPER BALL JOINT AND UPPER CONTROL ARM. 4. AFTER REPLACING ABOVE MENTIONED PARTS, NOISE WAS STILL PRESENT WHEN DRIVING SO DEALER REPLACED BOTH LEFT AND RIGHT FRONT STRUTS. 5. THE FOLLOWING MONTH RIGHT FRONT STRUT WAS REPLACED AGAIN DUE TO NOISE WHILE DRIVING. 6. ONE MONTH AFTER THAT SERVICE THE RADIATOR BEGAN LEAKING WHILE ON THE ROAD AND THE DEALER REPLACED THE RADIATOR. 7. 07/12/2017 LEFT FRONT STRUT WAS REPLACED AGAIN. THIS IS THE 4TH STRUT PUT IN THIS VEHICLE. 8. 07/12/2017 A/C STOPPED WORKING. DEALER SAID IT NEEDS NEW CONDENSER WHICH IS ON BACK ORDER INDEFINITELY AT THIS POINT SO NOT ABLE TO FIX AT THIS TIME. THESE ISSUES HAPPENED OVER A PERIOD OF 18 MONTHS. NOT AT A SPECIFIC TIME. THE STEERING COLUMN IS STILL MAKING A CLICKING NOISE WHILE TURNING. WE HAVE TAKEN THE VEHICLE BACK, HOWEVER THE DEALER SAYS THEY ARE UNABLE TO DUPLICATE THE NOISE. IF THEY END UP REPLACING THE STEERING COLUMN AGAIN IT WILL BE THE THIRD TIME. THIS VEHICLE IS NOT TRUST WORTHY TO DRIVE LONG DISTANCES OR CROSS COUNTRY. VERY DISAPPOINTING FOR A $70,000 NEW VEHICLE.

1PE18012 · Brake Vacuum Pump Failure
Opened Nov 20, 2018 · Closed Apr 10, 2022
Status: closed (inferred from source dates) · Service Brakes; Service Brakes, Hydraulic; Service Brakes, Hydraulic:power Assist:vacuum
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.
