What is the 2014 Cadillac ELR ESC Software May Not Warn When Stability Control Is Disabled (Recall 14V144)?

Certain 2014 ELR vehicles without adaptive cruise control were built with software that can inhibit some electronic-stability-control diagnostics. An ESC fault may therefore disable or degrade the system without illuminating the required malfunction warning, increasing crash risk… Severity: high.

What is the 2014 Cadillac ELR Front-Seat Hook-Bracket Weld May Be Incomplete (Recall 14V446)?

Certain 2014 ELR vehicles may have an incomplete weld on either front-seat hook-bracket assembly. Under a high load such as a crash, the hook can separate from the seat track and increase occupant-injury risk. Severity: high.

What is the 2014-2016 Cadillac ELR Sudden Total Loss of Electrical Power While Driving (Often With No Stored Codes)?

Multiple ELR owners report a frightening intermittent failure in which the car loses ALL electrical power without warning while driving - sometimes preceded by a loud 'pop' - taking out power steering, power brake assist, lights, hazard flashers, gauges and even door locks, forci… Repairs typically run $200-$4,000. Severity: high.

What is the 2014-2016 Cadillac ELR Charge Port Door Actuator Failure and Charging Issues?

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,… Repairs typically run $150-$600. Severity: medium.

What is the 2014 Cadillac ELR Brake-Rotor Corrosion or Thickness Variation Can Cause Pulsation?

GM bulletin 00-05-22-002N applies to 2014 and prior GM passenger cars and distinguishes cosmetic corrosion, lot rot, lateral runout, thickness variation and flaking. Applying it to the 2014 ELR is a scope inference; the bulletin does not establish regenerative braking as the caus… Severity: medium.

What is the 2014-2015 Cadillac ELR Low 12-Volt Battery Can Prevent Module Wake-Up; Diagnose the Cause First?

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. Severity: medium.

What is the 2015 Cadillac ELR Gradual High-Voltage Battery Capacity Loss Is Not the Same as a Fault?

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 unrel… Severity: medium.

What is the 2014-2016 Cadillac ELR CUE 8-Inch Display Bubbling or Delamination Needs ICS Inspection?

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 replacem… Severity: medium.

What is the 2014-2016 Cadillac ELR "Shift to Park" False Warning from Failing Electronic Shifter Park Switch?

The ELR uses an electronic precision shift lever that springs back to a center rest position and relies on an internal park-detent microswitch to confirm the transmission is in Park. On the ELR this internal park switch degrades and intermittently fails to send the 'in Park' sign… Repairs typically run $300-$600. Severity: medium.

What is the 2014-2016 Cadillac ELR Engine and Fuel Maintenance Modes Can Run the Engine With Charge Remaining?

The ELR can start its gasoline engine during documented Engine Maintenance Mode or Fuel Maintenance Mode even when battery charge remains. These modes keep the engine operable and consume aging fuel; they are normal operating behaviors, not proof of a propulsion-battery fault. Severity: low.

What is the 2014-2016 Cadillac ELR The Gas Engine Can Start With EV Range Remaining Under Normal Conditions?

Cadillac documents several normal reasons the ELR gasoline engine may start while battery charge remains, including low or high battery temperature, low high-voltage state of charge, an open hood and engine or fuel maintenance mode. That behavior alone does not establish battery… Severity: low.
