#737 of 752 Re: car starts by itself [user777] by gagrice Aug 09, 2006 (5:53 pm)
Replying to: user777 (Aug 09, 2006 5:04 pm) Myself I would rather dump a car with defects on the dealer. Most cars it is easy for them to find the defects and fix them. That is not the case with these "GHOST" problems associated with the hybrids. So you know the dealer will cover his behind and let the customer pay the price. I agree with user777 it would be hard for me to dump that kind of problem on some poor unsuspecting soul. If you follow these threads as I have. You will remember several such cases where folks bought a used Prius only to find out it had expensive problems to repair. Replies to this message: user777 (Aug 10, 2006 12:41 am)

Replying to: gagrice (Aug 09, 2006 5:53 pm) agreed. i believe in full disclosure. i don't believe in leaving it up to someone else to discover an issue which needs resolution. when selling vehicles used, i like to price it according to condition, and i will get an estimate as to how much it is to get something fixed, and then let the purchaser decide if he/she wants that amount taken off the otherwise BB/NADA value. by disclosing, i'm also allowing them to confirm something with their mechanic. as for "ghostly" issues involving high-tech - i honestly don't know what i could do... sure i'd like to "dump" it on a dealer rather than on a parent looking to buy a reliable vehicle for a son or daughter, or a single parent, or someone just out of school with shallow pockets and lots of loan debt, since there's probably gonna be some serious time, effort and expense resolving those sorts of things. last vehicle i sold had a serious issue and i discussed it with two mechanics, selling it to one of the mechanics that was willing to take on a project. i'd rather take a loss and feel good about what i did. i'd hate to be on the receiving side of an issue like that.

Replying to: rakers (Feb 02, 2006 5:07 am) Any further news on this one from anybody? Same thing just happened to my 2004 Prius at 42,000 miles. Replies to this message: trilliumg (Aug 13, 2006 6:11 pm)

Replying to: carpian (Aug 13, 2006 7:20 am) Same thing happened to me today, 2006 Prius at 1700 miles. Scary and bizarre. Need more info! I also just posted this problem on priuschat.com.
#741 of 752 Final story on the brake issue? by larsb Aug 17, 2006 (12:46 pm)
A few months ago we were hotly discussing the few reported "brake failures" and were trying to decide if it was a software problem causing the brake problem. Did anyone ever get a definitive answer on that?
#742 of 752 Prius died on I-40 by wentgreenin06 Aug 19, 2006 (8:07 am)
Am posting this from Amarillo TX, en route from East Coast to West for a move. My 2006, 2 week old Prius did the first 1500 miles or so of the trip just fine, then experienced the same exact problem described by others on this site and at NHTSA website. Specifically, at highway speed, the gas guage started reading abnormally low , then flashing on the last box, then multiple warning lights came on all at once, including general woarning, engine check, brake failure, and VSC. The gas engine died. I was able to limp to the next offramp (in the middle of the prairie) on electric. Walked to a gas station and put a gallon of gas in to no avail. "Add fuel" prompt was still on, which really made no sense as the car easily gets over 400 miles a tank and there were less than 300 on the current tank. A tow quickly came, and when we unloaded the car at the local Toyota dealer (about 2 hours later), the car seemed fine except for the engine check light being on. This morning the service manager called to say they couldn't find anything. Engine check light was no longer on. The only diagnostic codes that read abnormal could be explained by running out of gas, and that the car worked fine on a 36 mile test run. Am going to pick up the car now, but will stock up on water for when we're stranded again!

Replying to: wentgreenin06 (Aug 19, 2006 8:07 am) someone should contact that dealer and have them call the manufacturer and ask how that code was thrown by the system without the tank being empty? it would be one thing if your unit was out of fuel, but it wasn't. possibly there is a fuel pump or pressure/flow measurement problem. this is why someone needs to do some deeper analysis on the code thrown. did they document the diagnostic code on the repair order?

Replying to: user777 (Aug 19, 2006 8:15 am) We'll make sure it is documented, thanks. This is seeming to me not to be a problem that is limited to a specific model year, as I see postings of the same problem for models from 2001 through 2006 (on this forum and there are 2 others from 2006 on the NHTSA ODI website). About 24,000 cars were recalled from 2004 and 5 by Toyota for the problem, but clearly others NOT LIMITED TO THOSE IN THE RECALL are affected. It is clear from the postings that the same problem recurs and recurs, without resolution, prior to the car being recalled. It may also recur AFTER the recall treatment, (which is EITHER reprogramming OR just reloading the same software for the ECM??) but that is not clear. It would help if there were a log of whether the problem resolved after the recall "treatment" so those of us who put our hard-earned cash down on this fabulous new technology would not have to risk breaking down again. In my opinion, the burden is on Toyota to a) solve this problem and b) unthil they do, notify potential buyers this may occur. Went Green in '06 but Was Green Ready for Us?

Replying to: wentgreenin06 (Aug 19, 2006 8:42 am) I hate to sound like Toyota or the dealer, but you may have actually run out of gas. The bladder may have prevented you from fully filling up the tank last time you got gas. I read that if you do run out, one gal. isn't enough to reach the pickup. It takes two gal. min. Several posting have reported that. Reason is when moving the fuel pump can still get fuel because it's sloshing around. Once it can't any more, and you stop, the level is way down. It appears the designers left some space at the bottom of the tank for water and other debris. Replies to this message: wentgreenin06 (Aug 20, 2006 7:27 pm) pathstar1 (Aug 21, 2006 6:29 am)

Replying to: pathstar1 (Aug 19, 2006 10:57 am) You may well be right. After summing up my 1 gallon, 2 added (less one burned) by the dealer, then 9 gallons upon leaving the dealership, the car would have been on fumes at the time it failed. Having all the lights come on may be the car's way of reacting to running out of fuel. (A general alert light and fuel light would have been sufficient to convey the message.) What is puzzling is WHY the car ran out of gas. For almost 2000 miles the average mileage was 37 MPG, with tank ranges allowing us to fill up at just under 400 miles with no problem. The last fill-up before the breakdown was 10.1 gallons, which tripped the pump turnoff. The INFO:Consumption panel was reading 36 + MPG avg, and there were only 290 miles on the tank when it broke down. Where did the other 100 miles go? Using the gas guage is no help - it reads full until about 160 miles have gone by, and when the gas got low, it dropped precipitously through the last 3 boxes, allowing inadequate time to stop for gas - in Texas, anyway. Since then we have made it to the Grand Canyon, and the car, very fully loaded, is getting 42 MPG at 7000 feet elevation. We are also filling it every 150-200 miles.
