AIR BAGS: AIR BAG/RESTRAINT CONTROL MODULE
General Motors LLC (GM) is recalling certain 2019 Chevrolet Corvette ZR1 vehicles. Hard braking or acceleration may cause the sensing diagnostic module (SDM) to enter a fault state. As a result, the SDM will not provide crash sensing or deploy the necessary air bags in the event of a crash.
AIR BAGS:FRONTAL
General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. 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. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
AIR BAGS:FRONTAL
General Motors LLC (GM) is recalling certain model year 2015-2017 Chevrolet Silverado 2500 HD, 3500 HD, Tahoe, Suburban, GMC Sierra 2500 HD and 3500 HD, GMC Yukon, GMC Yukon XL, Cadillac Escalade and Cadillac Escalade ESV vehicles and 2014-2017 Chevrolet Corvette, Silverado 1500, Trax, Caprice Police Pursuit Vehicle, GMC Sierra 1500, Buick Encore, and 2014-2016 Buick Lacrosse, Chevrolet Spark EV and SS vehicles. In the affected vehicles, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
AIR BAGS
General Motors LLC (GM) is recalling certain model year 2015 Chevrolet Corvette vehicles manufactured August 20, 2014, to August 27, 2014. In the event of a driver frontal air bag deployment, the driver air bag module back plate may fracture, allowing the driver air bag to separate from the steering wheel.
PARKING BRAKE
General Motors LLC (GM) is recalling certain model year 2015 Chevrolet Corvette vehicles manufactured August 20, 2014, to September 4, 2014. In the affected vehicles, only one of the rear parking brake cables may be fully seated and engaged, resulting in the parking brake only operating on one of the rear park brake drums. Without the parking brake working on both rear wheels, the vehicle may roll away if parked on a steep gradient. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 135, "Light Vehicle Brake Systems."

The Active Fuel Management (cylinder deactivation) lifters in the 6.2L LT1 and LT4 mechanically collapse or stick in their bores, producing a persistent top-end tick and a misfire that sets P0300. GM's own bulletin identifies four failure paths: a mechanically collapsed or stuck… Repairs typically run $2,500-$7,500. Severity: high.
A damaged crankshaft thrust bearing allows excessive crankshaft endplay on both the LT1 and LT4. The symptom set differs by transmission, which is why it is often misdiagnosed. On manual cars owners report engine stalling, clutch chatter, and hard shifting into first gear or reve… Repairs typically run $3,500-$9,000. Severity: high.
The cast aluminum wheels fitted to the C7 Z06 (2015-2019) and Grand Sport (2017-2019) crack and deform under ordinary driving. Cracks initiate on the inner rim near the bead seat and propagate outward, producing a slow air leak that owners often first notice as a recurring low-ti… Repairs typically run $700-$4,000. Severity: high.
C7 Z06 models with the supercharged 6.2L LT4 overheat and enter a reduced-engine-power mode when driven at sustained high speed on a road course in warm ambient temperatures. The factory cooling package is undersized for the LT4's heat rejection: the supercharger uses only two in… Repairs typically run $0-$4,500. Severity: high.
On 2016-2019 LT1 and LT4 engines, coolant migrates into the combustion chambers from two casting defects: pinhole porosity at the cylinder liner-to-deck-face casting, and a compromised casting line inside the intake port of the cylinder head. Symptoms are white smoke and a sweet… Repairs typically run $3,000-$7,500. Severity: high.
C7 models with the 8L90 eight-speed automatic (RPO M5U) develop a torque converter clutch shudder that owners consistently describe as driving over rumble strips or rough pavement. It occurs under light throttle at a steady state between 25 and 80 mph while the transmission is no… Repairs typically run $300-$4,000. Severity: medium.
The C7 Corvette with the 7-speed manual or 8-speed automatic can develop an annoying driveline vibration/shudder at low speeds, particularly during gentle acceleration from a stop. The 7-speed manual uses a dual-mass flywheel that can develop chatter. The 8-speed automatic (8L90)… Repairs typically run $200-$2,500. Severity: low.
