2015 Buick Encore: engine and transmission complaints
HIGH COMPLAINT SIGNAL
41%
42 of 103 relevant owner complaints are about the engine, transmission or fuel system
41% of relevant owner complaints filed with NHTSA on the 2015 Buick Encore are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Better than 52% of the 1,230 model years we track (2010–2023).
Excludes 21 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 34%).
The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2015 Buick Encore
Ask the seller whether the engine has ever been repaired or replaced, and whether the car has shown stalling, loss of power, rough idle, oil consumption or a check-engine light.
Drive it from a cold start and long enough to warm up. Many engine faults hide once the car is warm.
Get an independent pre-purchase inspection from a mechanic you choose, and tell them to focus on the engine.
4 recall campaigns on this model year. Whether a specific car still has one open depends on the VIN; the report checks that.
Ask for service records. A engine already replaced under warranty is a different car from one that was not.
Have the VIN?Paste it and get the full report for that car. First report free, then a 30-day pass covers a whole car search.
Experimental model-level information. This is not a vehicle inspection, vehicle-history
report, financial advice or purchase recommendation. It describes patterns across a model year, not the condition
of any individual vehicle.
