2014 Chevrolet Ss

The 6L80 six-speed automatic transmission develops a torque converter shudder during light throttle at 35-55 mph, creating a vibration similar to driving over grooved pavement. The shudder is caused by the torque converter clutch slipping against the lockup friction surface. This is a widespread issue across GM vehicles using the 6L80/6L90 transmissions.

Perform a transmission fluid flush using Dexron HP ATF as the first-line treatment. If the shudder returns, the torque converter must be replaced. Reference GM TSB 18-NA-355 for torque converter shudder diagnosis. Some owners have had success with a complete fluid exchange followed by a torque converter clutch relearn procedure.

The rear differential pinion seal leaks gear oil, leaving a drip trail or puddle under the rear of the vehicle. The LS3 V8's torque output stresses the pinion seal over time. If the differential fluid level drops too low, the limited-slip differential clutch pack and ring-and-pinion gears can be damaged, resulting in an expensive repair.

Replace the rear differential pinion seal and inspect the pinion flange for wear grooves that would prevent a new seal from sealing properly. If the flange is grooved, install a speedi-sleeve over the wear mark or replace the flange. Refill with the correct 75W-90 synthetic gear oil and limited-slip additive.

The A/C system struggles to maintain cool cabin temperatures in ambient temperatures above 90 degrees F, particularly at idle or in slow-moving traffic. The condenser is undersized for the heat output of the LS3 V8 in a sedan platform. Owners report the A/C blowing lukewarm air and taking a long time to cool the cabin after sitting in the sun.

Ensure the A/C system is fully charged with the correct amount of R-134a refrigerant. Clean the condenser fins of bugs and debris that restrict airflow. Some owners install an auxiliary electric fan on the condenser for better low-speed cooling. Verify the A/C compressor clutch engages properly and the expansion valve is functioning.

The front and rear suspension bushings, particularly the rear cradle bushings and front lower control arm bushings, wear prematurely. Owners report clunking noises over bumps, an imprecise feeling in the steering, and degraded handling. The Chevy SS is based on the Holden Commodore platform, and Australian-sourced bushings are prone to faster wear on American road surfaces.

Replace the worn suspension bushings. Polyurethane aftermarket bushing kits (such as Nolathane or Whiteline) are popular upgrades that provide improved durability and tighter handling. A rear cradle bushing replacement addresses the most common clunking source. Perform a four-wheel alignment after any bushing replacement.

The power-folding side mirrors develop motor failures where the mirror vibrates or buzzes at highway speeds, fails to fold on command, or unfolds and refolds repeatedly. The mirror glass can also vibrate loose from the actuator plate, making it impossible to maintain a stable rearview image at speed. This is a common complaint specific to the Chevy SS and the Holden VF Commodore it is based on.

Replace the side mirror assembly or the internal mirror motor and actuator. GM parts for the SS are becoming scarce as the vehicle was produced in limited numbers (2014-2017). Some owners source replacement mirror assemblies from Holden VF Commodore parts suppliers in Australia. Aftermarket mirror motor rebuild kits are also available.

General Motors LLC (GM) is recalling certain 2014-2016 Chevrolet SS and Caprice Police Pursuit Vehicles (PPV) that were previously repaired under NHTSA recall number 16V-518. The repair may not have been performed properly. The driver's seat belt tensioner cable may be repeatedly bent over the seat side shield as the driver enters and exits the vehicle causing the cable to fatigue and separate.

If the tensioner cable separates, the driver may not be properly restrained in the event of a crash, increasing their risk of injury.

GM will notify owners, and dealers will inspect the vehicles to determine whether the new seat trim was installed and replace the trim as necessary. Dealers will also inspect and replace the pretensioner cable assembly, as necessary. Repairs will be performed free of charge. The recall began November 17, 2020. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N202312100

General Motors LLC (GM) is recalling certain 2014-2016 Chevrolet SS vehicles that previously received an inspect-only remedy under recall 17V-382.

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.

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.

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.
