Unfortunately ISG is not yet ready for prime time. I couldn't find a Rio5 on the lot without it, so I am stuck with it. It has some good points, but the bad outweigh the good. They must not have stop signs in South Korea because ISG shuts off the car at every one of them unless you "coast through" - I would think some law suits are already in the works regarding this issue. Who the hell thought of a system that shuts a car off at a stop sign!Yes, I've done that. A Kia engineer traveled across the country to look at my car and could not find a problem.
No - My ISG has never failed to restart. I have never had an error light or alarm come on. Marley Fan is right - this is definitely a dealer issue, but if it is intermittent they are going to have a difficult time diagnosing the problem.to Sdgc: I stop at a traffic light, sit during the light with my foot on the brake, take my foot off the brake and an alarm goes off and the car needs to be manually restarted.
to ELI 10: Has your ISG ever failed?
Eh? Driving 1 km in 1 minute is 60 km/h. Are you saying that idling is as thirsty as driving at 60 km/h?I agree about the ISG, not something I would consider (mind you I live out in the country) but having said that, each minute of idling is equivalent to driving 1 km.
The issue is fuel consumption at idle, not at acceleration. Both ISG cars and non ISG cars will accelerate the same and use the same fuel after the idle period.there is NO WAY its going to use the same as driving 1km, especially from a stop as you have to account for acceleration, which is the hardest on fuel consumption.
