Please accept our most sincere and unreserved apologies for the immense frustration and anxiety this situation has caused you. For a well-maintained, 10-year-old Corolla that has run smoothly until now, a drop from 32 MPG to 26 MPG alongside unusual exhaust fumes is completely unacceptable, and we understand why you are furious.
Even though the multi-point inspection at Firestone didn't flag an active trouble code, a sharp decline in fuel efficiency and unexpected odors strongly point to an unburnt fuel mixture or a subtle heat-range/electrode gap discrepancy affecting your 2015 Corolla's combustion efficiency.
Your vehicle’s engine health is our absolute priority. To respect your time and garage schedule, our team has already bypassed our standard return protocols and issued a 100% full refund back to your original account. You do not need to incur any labor or hassle to pull these plugs out to ship them back to us. An escalated service manager has reached out to your email with the transaction details and further assistance. Thank you for holding us accountable.
