Question About the ECO Light on Your Car

My girlfriend and I purchased a new Infinity M37S. The car has four automatic and a standard shift mode. In ‘ECO’ (economy) drive transmission gags or chokes down and barely picks up speed. Once, the car stalled at intersection after stoplight while in ECO drive. We were told to drive in standard mode and that works fine. To start our car you need to depress brake and often takes 3/4 minutes before engines turns over (engine won’t turn over as if batteries are dead). My battery was replaced after ten months but we still have the problem. I was told until they duplicate problem there is nothing they can do.

The ‘ECO’ button is common on cars that have been purchased in the past two years. The option gives the operator the ability to drive the car with more fuel efficiency. Usually this mode will run the car on less power, using less gas for more mileage. If we could get the vehicle to duplicate the problem, we could diagnose it. It may not be a transmission issue, it could be engine performance or a computer issue. We did a little research on this and it appears there is a re-mapping of the computer available. This has resulted in a 97% fix. The only place to have this type of work done is an Infinity dealership.
