Is the Cadillac ELR reliable?
The 2014-2016 Cadillac ELR has 11 known issues compiled from NHTSA recalls, manufacturer TSBs, and owner forum reports. 5 issues are rated critical: No-Charge or Service Charging Message Needs Charge-Receptacle Diagnosis and Low High-Voltage Cell Voltage Can Reduce or Remove Propulsion and Service High Voltage Charging System With P0DAA Needs Isolation Diagnosis and ESC Software May Not Warn When Stability Control Is Disabled (Recall 14V144) and Front-Seat Hook-Bracket Weld May Be Incomplete (Recall 14V446). Prospective buyers should inspect for these issues and factor potential repair costs into their purchase decision. Regular maintenance following the manufacturer's schedule helps prevent many common problems.
What is the 2014-2015 Cadillac ELR No-Charge or Service Charging Message Needs Charge-Receptacle Diagnosis?
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 unive… Severity: high.
What is the 2014-2016 Cadillac ELR Low High-Voltage Cell Voltage Can Reduce or Remove Propulsion?
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 capac… Severity: high.
What is the 2014 Cadillac ELR Service High Voltage Charging System With P0DAA Needs Isolation Diagnosis?
GM PIC5920B documents a 2014 ELR no-charge path with DTC P0DAA involving high-voltage isolation and possible heater, contactor, coolant-fill or internal isolation conditions. It does not support presuming a failed coolant-level sensor or simply topping off coolant and clearing th… Severity: high.
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 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 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 2014-2015 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 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 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.
