Common problems & what to inspect
Based on all 53 owner complaints filed with NHTSA for the 2021 Buick Encore GX, here are the most-reported problem areas — and what to check before you buy.
💥 2 involved a crash 🚑 4 reported injuries
🔍 Listen for knocks or ticking, check for leaks and blue/white exhaust smoke, and make sure it doesn't overheat. No check-engine light should be on.
🔍 Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
🔍 Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
🔍 Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
🔍 Check coolant level and color, look for leaks, and confirm the engine reaches normal temperature without overheating.
🔍 Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Pre-purchase checklist
- Match the VIN on the dash, door jamb and title — they must be identical.
- Cold-start the engine; listen for knocks and check for blue or white exhaust smoke.
- Test-drive through all gears at low and highway speed — no slipping, shudder or pulling.
- Confirm every warning light clears at startup (none should stay on).
- Check fluids — oil, coolant, transmission — for level, color and leaks.
- Look underneath for rust, fresh undercoating or signs of collision repair.
- Always get an independent pre-purchase inspection from a trusted mechanic.
