On the 2014-2015 Cadillac ELR, gM PIC6015A and PIC6076 cover bounded ELR no-charge and Service High Voltage Charging System paths. A cord, charging station, pilot-signal fault, cracked or water-affected receptacle, or an applicable HPCM2 calibration can produce the concern; the bulletins do not establish universal onboard-charger failure.

Common Symptoms

  • Vehicle will not charge
  • Service High Voltage Charging System message

How to Fix

Have a qualified technician record DTCs and freeze-frame data, rule out the cord and charging infrastructure, inspect the charge receptacle for cracks or water intrusion, and apply the current GM diagnostic or HPCM2 programming path when its criteria are met. Do not order charging hardware from this card.

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.

Common Symptoms

  • Charge port door does not release when pressed
  • Charge port door opens but won't close flush
  • Clicking noise from charge port area but door stays locked
  • Charge port LED ring not illuminating
  • Door freezes shut in cold weather

How to Fix

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.

Typical repair cost:$150 - $600

On the 2015 Cadillac ELR, cadillac warranty information for the 2015 ELR states that gradual high-voltage battery capacity loss is expected with time and use and distinguishes it from a warranted defect. That policy does not support a fixed range, age, balancing routine, individual-module repair, or unrelated 12-volt battery recommendation.

Common Symptoms

  • Gradual reduction in electric driving range

How to Fix

Track range under comparable temperature, route and climate-control conditions. Have abrupt range loss, warning messages, charging faults or reduced propulsion diagnosed separately. High-voltage battery inspection and service require qualified EV procedures; there is no owner-buyable repair on this card.

On the 2014-2016 Cadillac ELR, gM PIC6055B covers an 8-inch CUE integrated-center-stack display that bubbles or delaminates. The bulletin requires technicians to distinguish the condition from damage caused by cleaners or excessive force and does not establish a universal DIY digitizer repair or fixed replacement part number.

Common Symptoms

  • Bubbles beneath the CUE display surface
  • Display-layer delamination

How to Fix

Document the display condition and have a Cadillac technician apply PIC6055B. After excluding external damage, the bulletin directs replacement of the integrated center stack using the current VIN-correct service part and authorization path. Do not order a screen from this card.

On the 2014-2015 Cadillac ELR, a low ELR 12-volt battery can leave control modules unable to wake and prevent a normal start. GM also issued VIN-gated program 14395A for a bounded 2015 OnStar-module battery-drain condition; that program expired in 2017 and is not proof of a universal drain.

This issue also affects: Buick LaCrosse, Buick Regal, Chevrolet Cruze

Common Symptoms

  • Control modules do not wake
  • Vehicle will not enter Ready mode
  • Low 12-volt battery after parking

How to Fix

Test the AGM battery and charging state, preserve DTC and low-voltage history, and diagnose the source of discharge before replacement. For a 2015 vehicle, ask a Cadillac dealer to check VIN and program history. This card does not cover a sudden loss of power while driving and does not prescribe a battery or maintainer.

On the 2014-2016 Cadillac ELR, gM customer-satisfaction program N172130462 covered certain 2014-2016 ELR vehicles whose original HPCM2 calibration might not provide enough warning before a low high-voltage cell caused reduced or lost propulsion. The software adds warning time; it does not restore battery capacity. The program expired in 2021 and was not a recall.

Common Symptoms

  • Propulsion Power Reduced message
  • Loss of propulsion
  • Vehicle may not enter Ready mode

How to Fix

If reduced propulsion is active, stop in a safe location and arrange qualified EV service or towing. A Cadillac dealer should check the VIN, program and software history and perform the current high-voltage battery diagnosis. Do not assume current free coverage or order battery parts from this card.

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."
