WHEN DRIVING OVER A POTHOLE OR SMALL BUMP, THE SUSPENSION SEEMS TO LET GO AND THE CAR JUMPS VERY ABNORMALLY. WE ONLY HAD 30K MILES AND I BELIEVE THIS IS A SUSPENSION PROBLEM. THE SHOCKS MAKE A LOT OF NOISE WHEN WE GO TOWARDS A POTHOLE. WE WENT TO THE DEALERSHIP TO COMPLAIN ABOUT THE SHOCKS AND THEY SAID THERE WAS NO PROBLEM WITH THE SHOCKS. SOON AFTER, I HAD TO CHANGE THE FRONT LEFT SHOCK BECAUSE THE SERVICE DEPARTMENT SAID IT WAS LEAKING. THEY DID NOT NOTICE THIS IN THE BEGINNING AND SUDDENLY MADE ME PAY $650 TO CHANGE THE FRONT LEFT SHOCK. RECENTLY, I HAD TO GO CHANGE MY RIGHT SHOCKS AND PAY FOR THAT TOO, ANOTHER $700 DOLLAR SERVICE. IT IS UNACCEPTABLE TO HAVE BOTH OF MY FRONT SHOCKS CHANGED WITHIN 1 AND 1/2 YEAR. I AM NOT THE ONLY ONE WHO HAS BEEN HAVING THESE PROBLEMS, SEVERAL OF MY FRIENDS HAVE ALSO HAD THIS PROBLEM WITH THIS MODEL. WE HAVE ALL SENT FORWARD A COMPLAINT FOR THE NOISE AND SUSPENSION PROBLEMS. I BELIEVE IT CAN BE UNSAFE IN THE FUTURE IF IT IS NOT TAKEN CARE OF. THE STEERING WHEEL MAKES A LOT OF CLINKING NOISE WHEN TURNING. WE WENT TO THE DEALERSHIP AND HAD TO REPLACE THE STEERING WHEEL COLUMN WITHIN A MERE 20K MILES. THE DEALERSHIP DID NOT SEE ANY PROBLEM WITH THE SHOCKS OR STEERING WHEEL. WE CURRENTLY STILL HEAR A CLINKING NOISE, AS IF SOMETHING IS BROKEN ON THE INSIDE. MY WARRANTY IS OVER NOW AND THIS NEEDS TO BE FIXED. THIS SHOULD NOT BE A PROBLEM FOR A CAR THIS NEW AT ALL. IT IS UNACCEPTABLE AND I SHOULD NOT HAVE TO GO TO A DEALERSHIP AND WASTE TIME AND MONEY ON IT. THE SEAT ON THE RIGHT HAND SIDE HAS CRACKED TWO TIMES ALREADY. THE FRAME WAS CRACKED AND WE HAD TO HAVE IT REPLACED WITHIN THE WARRANTY TWO TIMES NOW. THIS IS RIDICULOUS AND THE SERVICEMEN HAVE ALSO NOTICED AND SAID THEY HAVE SEEN THIS PROBLEM AS WELL. MY WARRANTY IS NOW OVER AND I CANNOT GO BACK FOR A THIRD TIME TO FIX IT IF IT HAPPENS.

I FELT A SHUTTER TIME TO TIME AT START UP, AND WOULD FEEL LIKE THE WHEEL WOULD GRIP ON HARD TURNS BACKING UP, WAS LIKE THIS FOR A COUPLE OF DAYS. FILLED TANK & DROVE OUT OF TOWN, AT DESTINATION NOTICED LEAKAGE UNDER CAR, UNDER DRIVE SEAT. THOUGHT IT MIGHT BE CONDENSATION. VEHICLE SAT FOR 2 HRS., NO LEAKAGE VISIBLE AT START UP, AFTER STARTING VEHICLE NOTICE LEAKAGE BEGAN AGAIN AND THIS TIME AT A LARGER VOLUME, COULD SMELL THE FUEL. CALLED DEALERSHIP THEY PICKED IT UP ON TOW TRUCK, WHEN BACK END WAS LIFTED, A SIGNIFICANT AMOUNT POURED OUT FROM UNDER CAR. WAS TOLD THAT THE FUEL HOSE/FUEL PUMP HAS THE CAUSE DUE TO RUBBING. FIRST 3 WEEKS WAS TOLD PART WAS ON BACKORDER, THEN THAT IT WAS GOING TO BECOME A RECALL AND THAT THE PART NEEDED TO BE REDESIGNED AND THAT THERE WAS NO IMMEDIATE TIME FRAME FOR VEHICLE RETURN. I HAVE BEEN DRIVING A DEALERSHIP LOANER FOR 2 MONTHS NOW. DEALERSHIP ASKED IF THEY CAN "CRAFT" A PATCH TO GET MY VEHICLE OUT OF THE SHOP. I DENIED THIS, CONSIDERING I DON'T KNOW WHAT THE LEGALITIES WILL BE. VERY DISAPPOINTED IN CHEVY, THIS IS MY 3RD SUBURBAN/TAHOE AND I'M CONSIDERING FILING LEMON LAW.

BACK PASSENGER SIDE SEAT BELT(BENCH EXTREME BACK) WOULD NOT RETRACT. A CHILD WAS TRAPPED(12 YR OLD) IN THE BACK SEAT OF THIS NEW 2015 SUBURBAN SUV. THE SEAT BELT WAS SOMEHOW WRAPPED ALONG THE STOMACH AND HOOKED ON THE SEAT, WHILE TAKING OUT THE BELT, IT WAS STUCK AROUND THE STOMACH TIGHTLY AND WOULD NOT RETRACT BACK. IT WAS SO TIGHT AROUND THE STOMACH AND CHILD COULD NOT BREATH PROPERLY. I THINK THIS IS DESIGN MALFUNCTION WHERE THE SEAT BELTS WOULD NOT RETRACT. THERE WAS ANOTHER SEAT BELT IN THE SAME CAR WHICH WAS COMPLETELY OUT OF THE SEAT BELT WINDING SYSTEM, THIS WOULD NOT RETRACT AT ALL. THIS CAR WAS TAKEN FROM A NATIONAL RENT A CAR CENTER.

Oct 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.

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.

While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition.

During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.

Consequence & remedy

Consequence: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.

Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017.

PE18012 · 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.
