ADVICE NEEDED! Anyone have same issues or technical, mechanical input. I put a call in Subaru America and taking to dealer today as recommended for diagnostic.
21 Crosstrek Sport - 44k miles
Just had CEL come on and downstream O2 Oxygen sensor failed and replaced by Subaru Dealer
Battery starting to fail trouble autostarting at stops
Now after last repair it is starting bucking again at cold starts. I am thinking it is possibly the upstream O2 sensor (still original) or another other issue
Gas mileage has always been below EPA Mpg
My Average 18-21 MPG (according to trip OD)
EPA at 27 mpg city/34 mpg highway/29 mpg combined
All service had been up kept by Subaru Dealer purchased new with warranty
New Gold Plus New Gold Plus 5yr/100,000-$100 deductible
Fortunately this covered O2 sensor with $100 deductible (I was going to buy OEM part and change myself)
