Replying to: wentgreenin06 (Aug 20, 2006 7:27 pm) Filling when there are still two bars lit is the way to go, according to many owners. Especially when travelling, not knowing where the next station is. Most owners are calling the fuel gauge a "guess gauge". If you keep records of fillups (always a good idea so you can watch for strange behavior), check back to see if the mileage suddenly dropped. The records I'm referring to is: odometer reading : miles since last fill : gal put in : mileage calculated : mileage indicated Only then can you figure out what happened. I suspect that either of two things: The bladder prevented you from properly filling the tank, or You were bucking a severe headwind, or there was a temporary fault in the system that impacted the mileage severely. I think the reason the car reacts like that is there is no special alarm subroutine in the program for running out of fuel. When you run out the ICE stops without being commanded to, and that triggers the warnings.

The car was fine before that other than the occasional check engine light after restarting the car after a long trip. After the reprogramming - now I get alot of the electrical type failures reported by others - radio cuts off, display disappears, climate screen says air conditioner is not connected, check engine light and problem warning come on all the time and I the problems get worse after restarting the car while it's hot. I haven't talked to the dealer yet but they better cover this. I lodged a complaint on the NTSB website. Replies to this message: midnightcowboy (Sep 08, 2006 5:42 am)

#751 of 752 press request by kirstie_h HOST Sep 08, 2006 (9:51 am)
A large national newspaper is doing a story on how cars increasingly are computers. The reporter is looking for people with cars that have had difficulty getting repaired because of the knowledge needed to fix them or the code requirements needed to fix are often not provided to non-dealers, or the cost to fix was outrageous. Please send an e-mail to ctalatiedmunds.com no later than Wednesday, September 13, 2006 by 2:30 PM PT/5:30 PM ET containing your daytime contact information and what car you currently own and the issue.
