2014 Buick Encore Problems (Explain Cause & Simple Fixes)

The 2014 Buick Encore is a great compact SUV, but like any vehicle, it’s not without its issues.

Common 2014 Buick Encore problems include engine trouble, transmission glitches, and electrical quirks.

This guide will explain the causes behind these issues and provide simple fixes, helping you keep your car running smoothly without unnecessary hassle.

1. Transmission Problems

Cause

The 2014 Buick Encore’s six-speed automatic transmission often experiences issues due to faulty valve body components and worn transmission fluid.

Poor shifting patterns and delayed engagement typically result from inadequate lubrication and overheating.

Manufacturing defects in the transmission control module can also contribute to erratic behavior during gear changes.

Fixes

Replace the transmission fluid with GM-approved ATF and check for leaks regularly.

Have the transmission control module reprogrammed or replaced if diagnostic codes indicate electronic failures.

For severe cases involving internal damage, a complete transmission rebuild or replacement may be necessary to restore proper function.

2. Engine Stalling and Power Loss

Cause

Sudden engine stalling often stems from a faulty throttle body or malfunctioning mass airflow sensor.

Carbon buildup on intake valves restricts proper airflow, while contaminated fuel injectors disrupt the fuel delivery system.

The engine control unit may also develop software glitches that cause unexpected power interruptions during normal driving conditions.

Fixes

Clean the throttle body and replace the air filter to improve airflow efficiency.

Have the fuel injectors professionally cleaned or replaced if they’re severely clogged with deposits.

Update the engine control unit software through a dealership service to address known programming issues that cause stalling problems.

3. Electrical System Malfunctions

Cause

The 2014 Encore’s electrical problems often trace back to corroded wiring harnesses and failing alternator components.

Moisture infiltration through damaged seals causes short circuits in various electrical systems.

The body control module can also malfunction due to voltage fluctuations, leading to intermittent failures in lights, windows, and other electronic features.

Fixes

Inspect and replace any corroded wiring connections, especially in areas exposed to moisture and road salt.

Test the alternator output and replace it if charging voltage falls below specifications.

Have the body control module reprogrammed or replaced if diagnostic scans reveal internal component failures affecting system communication.

4. Cooling System Issues

Cause

Coolant leaks commonly develop from cracked radiator hoses and failing water pump seals in the 2014 Encore.

The plastic radiator end tanks become brittle over time and crack under pressure changes.

A malfunctioning thermostat can also cause overheating by restricting coolant flow, while air pockets in the system prevent proper heat transfer.

Fixes

Replace damaged radiator hoses and inspect all cooling system connections for leaks or wear signs.

Install a new water pump if seepage appears around the pump housing or pulley area.

Flush the cooling system completely and bleed out air pockets to ensure proper circulation and temperature regulation throughout the engine.

5. Brake System Problems

Cause

Premature brake pad wear occurs due to aggressive driving habits and poor-quality friction materials in some 2014 Encore models.

Brake rotors often warp from excessive heat buildup during heavy braking situations.

The brake fluid can also become contaminated with moisture over time, reducing stopping effectiveness and causing corrosion in hydraulic components.

Fixes

Replace worn brake pads with high-quality aftermarket or OEM parts for better longevity and performance.

Resurface or replace warped rotors to eliminate pedal pulsation and ensure smooth braking action.

Flush the brake fluid every two years to remove moisture contamination and maintain proper hydraulic system operation.

6. Air Conditioning Failures

Cause

AC compressor failures in the 2014 Encore typically result from refrigerant leaks and contaminated system oil.

Blocked expansion valves prevent proper refrigerant flow, while damaged condenser fins reduce heat exchange efficiency.

Electrical issues with the AC clutch relay can also cause intermittent cooling problems during hot weather conditions.

Fixes

Locate and repair refrigerant leaks using UV dye detection methods and specialized equipment.

Replace the AC compressor if internal damage is detected during pressure testing procedures.

Clean debris from the condenser fins and check electrical connections to ensure proper AC clutch engagement and system operation.

7. Fuel System Complications

Cause

Clogged fuel filters restrict gasoline flow to the engine, causing hesitation and reduced power output.

The fuel pump can fail prematurely due to contaminated gasoline and electrical connection problems.

Carbon deposits on fuel injector tips disrupt spray patterns, leading to poor combustion efficiency and increased emissions from the exhaust system.

Fixes

Replace the fuel filter according to maintenance schedules and use high-quality gasoline from reputable stations.

Test fuel pump pressure and replace the unit if output falls below manufacturer specifications.

Have fuel injectors professionally cleaned or replaced to restore proper spray patterns and combustion efficiency in all cylinders.

8. Suspension Component Wear

Cause

Front strut assemblies wear out quickly due to poor road conditions and aggressive driving over potholes.

Worn control arm bushings create excessive play in the suspension system, affecting wheel alignment and tire wear patterns.

Ball joints can also deteriorate from contamination and lack of lubrication, causing steering instability and noise during turns.

Fixes

Replace worn strut assemblies with quality aftermarket or OEM parts to restore ride comfort and handling.

Inspect control arm bushings regularly and replace them when cracking or separation becomes visible.

Lubricate ball joints according to service intervals and replace them if excessive play develops in the steering components.

9. Window Regulator Malfunctions

Cause

Power window motors fail due to worn brushes and overheating from frequent use in extreme temperatures.

The window regulator tracks become misaligned when mounting bolts loosen over time.

Damaged window switches can also prevent proper operation, while corroded wiring connections interrupt electrical signals to the motor assemblies.

Fixes

Replace faulty window motors and lubricate regulator tracks to ensure smooth glass movement.

Tighten loose mounting hardware and realign tracks if windows bind or move unevenly.

Clean electrical connections and replace damaged switches to restore full power window functionality in all door positions.

10. Ignition System Problems

Cause

Spark plug fouling occurs from carbon buildup and improper fuel mixtures in the 2014 Encore’s engine.

Ignition coils can fail due to heat stress and electrical overload conditions during extended driving periods.

The ignition control module may also develop internal faults that cause misfiring and rough idle conditions at various engine speeds.

Fixes

Replace spark plugs with the correct heat range and gap specifications for optimal combustion performance.

Test ignition coils individually and replace any units showing weak or inconsistent spark output.

Have the ignition control module diagnosed and reprogrammed or replaced if diagnostic codes indicate electronic component failures affecting engine operation.
