10 Common 2016 Buick Encore Problems (Causes & Simple Fixes)

The 2016 Buick Encore is a compact SUV that offers style and comfort, but like any vehicle, it comes with its share of issues. 

If you’re experiencing 2016 Buick Encore problems, you’re not alone. Many owners report similar concerns that can affect performance and reliability. 

Understanding these common issues, their causes, and how to fix them will help you keep your Encore running smoothly and avoid costly repairs down the road.

1. Transmission Shuddering and Hesitation

Cause

The shuddering usually stems from low or contaminated transmission fluid. 

Over time, the fluid breaks down and loses its ability to lubricate and cool the transmission properly. 

Worn torque converter clutches can also contribute to this issue.

Fixes

Start by checking your transmission fluid level and condition. 

If it’s low or dirty, perform a transmission fluid flush and refill with the manufacturer-recommended fluid. 

If the problem persists, the torque converter may need replacement, which requires professional service.

2. Engine Stalling at Idle

Cause

This issue often relates to a faulty throttle body that becomes clogged with carbon deposits. 

A malfunctioning idle air control valve or vacuum leaks can also cause stalling. 

These components regulate air intake when the engine is idling.

Fixes

Clean the throttle body using a throttle body cleaner spray and a soft cloth. 

Inspect vacuum hoses for cracks or disconnections and replace any damaged hoses. 

If cleaning doesn’t resolve the issue, the throttle body or idle air control valve may need replacement.

3. Excessive Oil Consumption

Cause

The 1.4L turbocharged engine in the Encore has a known issue with piston ring design that allows oil to seep into the combustion chamber. 

Worn valve seals and a malfunctioning PCV (positive crankcase ventilation) system can also contribute to oil consumption.

Fixes

Check your oil level regularly and top it off as needed to prevent engine damage. Replace the PCV valve if it’s clogged or faulty. 

For severe cases, piston rings or valve seals may need replacement, which is a major repair best handled by a qualified mechanic.

4. Water Pump Failure

Cause

The water pump can fail due to worn bearings, a damaged impeller, or seal deterioration. 

The placement of the water pump inside the engine makes it more prone to premature wear from heat and vibration.

Fixes

If you notice coolant leaking or your temperature gauge climbing, stop driving immediately to avoid engine damage. 

Replace the water pump along with the timing belt or chain, as they’re often serviced together. This repair typically costs between $500 and $800 at a repair shop.

5. Turbocharger Problems

Cause

Turbocharger failure typically occurs due to oil starvation, which happens when oil changes are delayed or the wrong oil is used. 

Carbon buildup in the turbo system and damaged seals can also cause problems.

Fixes

Follow the manufacturer’s recommended oil change intervals using the correct oil grade. 

If the turbocharger is damaged, it will likely need replacement. 

Regular maintenance and allowing the engine to cool down before shutting it off can help extend turbo life.

6. Electrical System Glitches

Cause

These electrical issues often trace back to software glitches in the vehicle’s computer systems. 

Corroded or loose battery connections, a weak battery, and faulty sensors can also trigger electrical problems.

Fixes

Start by checking your battery connections for corrosion and ensuring they’re tight. 

Have your battery tested, as a weak battery can cause multiple electrical issues. 

For software-related problems, visit your Buick dealer for a software update or system reset.

7. Suspension Noise and Wear

Cause

Worn stabilizer bar links and bushings are the most common culprits behind suspension noise. 

Strut mounts can also deteriorate over time, leading to noise and reduced handling performance.

Fixes

Have a mechanic inspect your suspension components for wear. Replacing worn stabilizer bar links and bushings is relatively affordable, typically costing $200 to $400 for parts and labor. If struts are worn, replacing them as a set will restore ride quality.

8. Timing Belt/Chain Issues

Cause

Timing chain stretch occurs due to inadequate lubrication, often caused by infrequent oil changes or low oil levels. 

The tensioner that keeps the chain tight can also weaken, allowing excess slack in the chain.

Fixes

Address timing chain issues promptly, as a broken chain can cause catastrophic engine damage. Replace the timing chain, tensioner, and guides as a complete set. 

This is a labor-intensive repair that typically costs between $800 and $1,500.

9. Brake System Problems

Cause

Brake problems can result from low-quality brake pads that wear quickly or accumulate excessive dust. 

Contaminated brake fluid that absorbs moisture over time reduces braking efficiency. 

Warped rotors from overheating can also cause vibration and noise.

Fixes

Replace brake pads with high-quality aftermarket or OEM parts to improve longevity. 

Flush and replace brake fluid every two years to maintain proper brake function. 

If rotors are warped, have them resurfaced or replaced depending on their condition.

10. Check Engine Light and Sensor Failures

Cause

Sensor failures typically occur due to contamination, electrical connection issues, or simply reaching the end of their service life. 

Vacuum leaks in the intake system can also trigger sensor-related codes.

Fixes

Use an OBD-II scanner to read the trouble codes and identify which sensor is causing the problem. 

Replace faulty sensors and clean or repair electrical connections.

After repairs, clear the codes and drive the vehicle to confirm the light stays off.
