2013 Buick Encore Owner Comments

problem #1

Oct 212021

Encore 1.4L

  • Automatic transmission
  • 76,000 miles

I've had catalytic convertor replaced and engine light came back on after 1 day. Then they replaced the O2 sensor.

Engine light is back on again. Replaced air hose.

Engine light back on again. Replaced spark plugs and coil pack.

Engine light didn't go off. By now it's July and time to have inspection. It won't pass inspection.

I am told this 1.4L turbo 4 cylinder has LOTS of Tech. service bulletins and I should get rid of it .
