2006 Toyota Prius Owner Comments

Twice in one week, on the highway, with one led segment remaining on the fuel gauge, the car quit dead and rolled out luckily to the side of the road. Out of fuel. Low level light came on each time. Genuine hassles getting to a gas station on foot on the interstate to get a container of gas to get running again. Two different Toyota service managers insisted nothing is wrong with the measuring system and that one should never trust a gauge or allow the level to get near zero. Not even one segment low! never, in all my years of driving have I had a car run out of gas with fuel indicated on the gauge. We additionally own another Prius (2005) which can run safely and not quit shortly after the low fuel warning comes on or all segments vanish. This is unsafe as one is forced to do emergency evasive action to the side of the road, then risk life walking on the interstate. Our solution the last few year is never do we let fuel level get below 2 led segments since.

2006 Prius was arriving at work and pulling into a parking space. My foot was removed from gas, but accelerator stuck open. The car bounced over the concrete curb, over a snow bank and over a second curb into the university driveway. Car sustained $3800+ in body damage and another $370 in service repairs for brakes, tires, suspension and dash warning systems that erupted. Vehicle was recently repaired. Local dealer would not accept any responsibility or acknowledge any problems with the car. Final repair invoice states the vehicle floor-mats, ABS and pedal stroke sensors were all working properly. Claim was made to our insurance company [erie insurance].

Passenger side hid headlight goes out every 3-4 months. At first it is intermittent, and difficult to say when failure occurs. Over time the period for failure gets shorter. Dealer says it is my problem. Cost of continual repair is over $300. Per light. Also, fuel gauge say add fuel when tank partially empty.

Hard time getting gas in the vehicle. For example, I was told by the dealership to let the gas gauge get down to 1/4 tank or less and fill the tank slowly as there may be air behind the bladder that is in the gas tank on the Prius. About 2 miles from the gas tank the "add fuel" warning came on in the vehicle. Upon pulling into the gas station and adding gas into the vehicle I was only able to get slightly over 4 gallons into the tank. The Prius had an 11.9 gallon gas tank. So if the gas was really below 1/4 tank, why am I only getting 4 gallons in the tank. Even if the 1/4 tank means there are 3 gallons left in the tank, those 3 plus the 4 that I got in the tank still only add up to 7 gallons. What happened to the other 4+ gallons that I should have been able to put in the tank" this happens every time I put gas in the vehicle. So far the dealership has told me its because its cold outside that this happens... well how do they explain it in summer" it was over 60 degrees when I got gas last Thursday. The have told me that I have to put the gas in slowly, and they have re-set the gas gauge.

On September 23, 2007, I was traveling on I-70 returning from bloomington Indiana to webster groves Missouri. As I was driving the add fuel light came on. Based on my previous experience, I knew I had at least 40 miles. All of a sudden, all of the warning lights came on and the car lost power. Luckily I was able to maneuver to the shoulder. I got the car to go a little further before it died on the ramp of the next exit. The total miles traveled from the time the add fuel light came on until the car completely died was 18 miles. I notified Toyota and their response was that I ran out of gas. They told me I should have 50 miles or so from when the add fuel light came on before running out of gas. They could not explain why I only got 18 miles. I told them that I believe there is something wrong with the fuel sensor and that this is a safety issue since my car died while traveling on an interstate. Toyota said it was not a safety issue since they have not had many complaints about this. For what it is worth, it was a very hot day and I had been traveling about 3 hours or so. My guess is that the fuel sensor is not accurate under these conditions. I asked Toyota why I only got 18 miles after the add fuel light came on. The representative could offer no explanation. At no time did Toyota check the fuel sensor.

A gasoline and or oil smell in the car that permeates everything in the car. My clothes, computer bag, papers, just everything that comes in contact with the inside of the car. I also get sick from the odor ie headaches, nausea, blurred vision, dizziness. I also have a burning taste in my mouth, throat and eyes. I have been to the doctors and they there is no other reason for me to be feeling the way I do and that it is the environment of my car that is producing this very serious irritant. The dealer service center said it is from the broken bearing that was replaced, broken and not my fault. This must also be a recall problem because they said it happens alot.

Gas tank gauge says its completely full no matter how much fuel is in the tank. As of this writing I have driven approx. 120 miles on this tank of gas and the gauge still shows the tank as full. It has not yet been fixed.
