asked by on

How do I keep ECON on? It reverts to SPORT shortly after I choose it.

My car has 16000 miles.
My car has an automatic transmission.

Hello there, if your 2016 Acura TLX will not stay in ECON mode there is a problem. If the ECON mode will not stay engaged the most common fault are a wiring harness fault, mode selector switch failure, or a failing IDS module. A qualified Technician such as one from YourMechanic will be able to diagnose your ECON mode fault and make any repairs required.
