On the 2014-2016 Cadillac ELR, the Cadillac ELR (based on the Chevrolet Volt platform) uses a 16.5 kWh lithium-ion battery pack rated for 37 miles of EV range. Owners report noticeable capacity degradation after 5-7 years, with usable EV range dropping to 25-30 miles. The battery management system restricts capacity as cells degrade. While GM's Voltec system is generally more reliable than pure EV batteries due to active thermal management, the ELR's limited production means replacement battery modules are scarce and expensive.
Battery capacity loss is gradual and the vehicle remains fully functional with the range-extending gasoline engine. GM warranty covers the battery for 8 years/100,000 miles. If battery modules need replacement, a Voltec-certified shop can replace individual cell groups rather than the entire pack. Maintaining the battery between 20-80% charge and avoiding extreme heat exposure slows degradation.

On the 2014-2016 Cadillac ELR, the ELR's motorized charge port door frequently fails to open or close properly. The electric actuator motor that operates the charge port door jams or the pivot hinge corrodes, preventing the door from releasing. In cold weather the door can freeze shut. If the door won't open, the vehicle cannot be plugged in for charging. The charge port light ring may also fail to illuminate or show incorrect colors.
Replace the charge port door actuator assembly (GM 22828424). If the door is frozen, gentle warming with a hair dryer (not heat gun) can free it. Lubricate the hinge and latch mechanism with silicone spray every 6 months as preventive maintenance. The LED light ring module can be replaced separately.

On the 2014-2016 Cadillac ELR, the 12V auxiliary battery is prone to parasitic drain, especially when the vehicle is left unplugged for extended periods. Unlike a conventional car, the ELR cannot start if the 12V battery is dead even if the main traction battery is fully charged. The vehicle's electronics draw from the 12V system even when off.
Replace the 12V battery with a quality AGM battery — the original battery often fails within 3-4 years. Keep the vehicle plugged in when parked for extended periods, as the Voltec system maintains the 12V battery when plugged in. A battery tender connected to the 12V battery is recommended for long-term storage.

On the 2014-2016 Cadillac ELR, the ELR, based on the Chevrolet Volt platform, experiences onboard charger failures and communication issues with Level 2 EVSEs. The charging module may fail to initiate charging, stop mid-charge, or throw fault codes. The 120V Level 1 EVSE included with the car is also known to have reliability issues.
Have the dealer diagnose the specific fault code. The onboard charger module may need replacement. Try different EVSEs to rule out charging station issues. Update the vehicle software to the latest calibration. The Voltec warranty may cover charging system components for 8 years/100,000 miles.

On the 2014-2016 Cadillac ELR, the ELR's regenerative braking system means the friction brakes are used very infrequently, especially in city driving. This causes the brake rotors to develop surface rust and corrosion that is not worn away by normal pad contact. The corroded rotors create pulsation, vibration, and reduced braking effectiveness. Brake pads can also seize in the caliper brackets from lack of use. This is a common issue across all plug-in hybrid and EV vehicles but is exacerbated on the ELR due to its aggressive regen-on-demand paddle.
Perform monthly highway-speed brake applications to clean rotor surfaces — 3-4 firm stops from 60 mph. Have brake pads removed, cleaned, and re-lubricated with ceramic brake grease at every tire rotation. If rotors are pitted from corrosion, they must be resurfaced or replaced. Use coated or ceramic-coated replacement rotors for better corrosion resistance.

ELECTRONIC STABILITY CONTROL (ESC)
General Motors LLC (GM) is recalling certain model year 2014 Cadillac ELR vehicles not equipped with adaptive cruise control and manufactured September 26, 2013, through February 14, 2014, and equipped without adaptive cruise control. In these vehicles, the electronic stability control (ESC) system software may inhibit certain ESC diagnostics, preventing the system from alerting the driver that the ESC system is partially or fully disabled. As such, these vehicles fail to conform with Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic Stability Control Systems."
SEATS
General Motors LLC (GM) is recalling certain model year 2013-2014 Buick Encore and Cadillac ATS; 2014 Cadillac CTS, ELR, Chevrolet Caprice and SS vehicles; and 2014-2015 Chevrolet Silverado and GMC Sierra Trucks. Due to an incomplete weld on the seat hook bracket assembly, the front seats in the affected vehicles may not stay secured in place during a high load condition such as a crash.
