- 2013 Encore
Hello my Encore with 62k miles has been getting low MPG, and sluggish acceleration. Last year had a bad catalytic converter replaced under dealer warranty, and it seemed okay for a while but still only 23MPG and sluggish acceleration lately. I needed front flex hose replaced, resulting in slightly tighter acceleration but still reduced mpg down to 19mpg after re-setting on on the dash. Mechanic then recommended dry gas which I added. Very next day, the check engine light goes on and the diagnostic codes now says its catalytic converter. Ugh! Suggestions please? Should I take it back to the dealer to check the 9 mos old catalytic converter and/or have the flex hose repairman double-check all his work? Who do i trust? I already feel like a ping pong ball getting bounced back and forth. Do other 2013 Buick Encore owners have problems with the exhaust and catalytic converter low MPG Etc?
