Filed Dec 11, 2018 · Acceleration, Electrical · 225,000 miles · CA

Combination meter intermittently not functioning. When turning the car on, sometimes the dash meter works, sometimes it's just black and continues the entire time the car is running. Then when trying to turn the car off, it will not turn off, which is a major safety concern. When this occurs, there are no dash lights at all to indicate fuel amount, odometer reading, door open signal, check engine, maintenance required and so on. The speed being driven is not showing either which is another major safety issue. Cruise control also does not function, the center touchscreen does not display hybrid motor information or mpg. The beeping when backing up does not function. Also the rear hatch will not open while car is running which is also a major safety issue in addition to all of the other functions not available. The odometer is not recording mileage during these times which makes it difficult to do proper maintenance that goes by mileage, such as oil changes.

Tl* the contact owns a 2005 toyota prius. The contact stated that while driving with the cruise control activated at 75 MPH, all of the warning indicators on the instrument panel illuminated in addition to the inverter cooling system warning message displaying. The contact shut off the engine but the failure was still present once restarted. The vehicle was included in the federal safety agency campaign id number 12v536000 (engine and engine cooling, hybrid propulsion system) however, the contact was not able to have the vehicle repaired because there was not a qualified technician to perform the repair at the local dealer. The contact received the recall notification six months prior and the dealer was unable to provide an expected date of when the vehicle could be serviced under the recall. The manufacturer was notified of the problem. The approximate failure mileage was 153,000.

Petition for an investigation into defect conditions in upper immediate steering extension shaft #2 manufacturing defect in the 2004-2009 toyota prius vehicles w/respect to recall 12v‑537. *smd an inspection revealed that the current loss of steering issue was caused by a catastrophic failure of the upper steering intermediate shaft. The upper steering intermediate shaft was decoupled from the electric- power- assist column output spline. A careful examination of the decoupled components revealed that for an extended period of time, the upper steering intermediate shaft had not been properly installed on the spline output of the power assist column. This allowed a metallurgical failure on the interior of the upper steering intermediate shaft, which consequently allowed separation of that shaft from the electrical steering power assist column. An examination of the shaft spline showed a long term deterioration of the upper intermediate shaft #2 inside spline as evidence by metallurgical shards of deteriorated spline metal still residing in the upper intermediate shaft cavity. Also, the cruise control would cancel and not re-engage, then there were times, where the cruise control would not dis-engage at all. The vehicle would drift off course whenever the consumer took his eyes off the road, for even a moment. The consumer would have to steer the vehicle constantly or it would drift into another lane. Apparently, it was due to a computer algorithm that would attempt to correct for wind and road surface anomalies.

Tl* the contact owns a 2005 toyota prius. The contact stated that while driving approximately 70 MPH with the cruise control activated, he applied the brake pedal in an attempt to deactivate the cruise control. The cruise control would not deactivate and the contact had to manually deactivate the cruise control system. The contact also stated that he heard a snapping sound coming from the steering wheel while attempting to park at 5 MPH. This failure occurred the day after the cruise control failure. The steering wheel then became loose and the contact completely unable to steer the vehicle. The vehicle was not taken to the dealer for a diagnostic test. The vehicle was not repaired. The approximate failure mileage was 27,773 updated 12/12/11 *bf the consumer stated the SRS and all the steering wheel mounted controls were disabled. Updated 05/31/12 the consumer contacted an automotive systems analysis company, who inspected the vehicle and determined the steering issue was caused by a catastrophic failure of the upper steering intermediate shaft.

When starting the vehicle up, no speedometer display is illuminated. The display for the vehicle environmental controls (miles per gallon/energy use) still works. Along with the speedometer display, the rear hatchback door does not work. I tried to adjust the inside light display to see if the light level was turned off. This was not problem. I turned the light adjustment knob in both directions, and still no speedometer display. Upon trying to turn off the engine, it will not turn off. I was able to shut the vehicle off by disconnecting the car battery in the passenger side rear hatch back area. Note that because the rear hatch back door does not work, all the vehicle parts which leads to the rear battery has to be taken out from the rear seat of the vehicle. One particular time I disconnected the car battery on the black portion of the battery,and the vehicle did not shut off. I brought the vehicle to the toyota dealership several times, and because this problem happens intermittently. Toyota was unable to duplicate it. However, one day when it was not working, I brought it in to them. They later claimed that it was a "cold start" problem to the computer that is responsible for the speedometer display (besides other things, rear hatch back door, cruise control, etc.). Toyota claimed they found the problem on the internet, and it was not a recalled part. This particular part (computer) normally happens only in the states that are very cold.

On 7/31/11 I noticed my cruise control would not set. The light came on indicating the cruise was on, but I could not get the speed to hold. The next day, the cruise control worked. Midday on 8/1/11 while parked, I shifted to the d position, but the light indicated I was in n. I shifted back and forth between r and d several times, but the light indicated n. I took my foot off the brake and the car moved backward. The light indicated n and the knob was in the d position. It did this several times. I turned the car off and back on and everything worked like it is supposed to. On 8/1/11 at approximately 10:30 p.m. I was driving home on a narrow, two-lane rural highway. On a blind curve, both of my headlights went out. I could not see anything. I tried cycling my headlights off and on and nothing happened. I applied my brakes and stopped. I opened my door to see where I was in the roadway and determined I was on the fog line on the opposite side of the road and there was a hillside less than 5' from me. I was able to drive to the shoulder on the right side of the road by using the light from my door. I was extremely lucky no cars passed by while my lights were out. I could have been killed or caused a catastrophe. I turned the car off and back on and both headlights came back on. A motorist stopped to assist. I was able to follow him to a store where a friend met me and I followed him home. During the drive home one of my headlights kept turning off. Both did not go off together again. I took the car to the dealer on 8/3/11 and was told I need a new auxiliary battery and two new headlights. Cost is going to be around $700. I read about a class action suit regarding 2006-2009 prius' headlights and that toyota knows there is a problem with them. I believe there should be a recall because of my harrowing experience and those of many others.

Yesterday on a long trip through the mountains, lights came on my dash on my 2005 toyota prius that indicated a hybrid problem. Hoping to get to a place where I could get service I continued on. (I also noted that the cruise control light would not come on.) then the brake light and ABS came on the dashboard with an auditory alarm. I tested the brakes and they seemed okay and there was no berm to pull off. Then I hit the brakes on a curve and the peddle went down low. I pressed hard and got it off the road on a wide spot that by the grace of god appeared. I had it towed to the nearest dealer. Today, the dealer said they checked all codes and inspected the braking system and can find nothing wrong and all codes have left. They said the hybrid battery seemed to be low but they find the battery and charging system to be ok. (they said brakes do not work when the battery is low and the battery is charged by braking which I was doing plenty of in the mountains.) they also said the computer is ok. They drive it and nothing is wrong.

I drove a 2005 toyota prius VIN#[xxx] until 5/13/2010. At around 10am I was driving on the hwy in the lft lane. With cruise control on going 75mph. I had a GPS on and navigating. And I had my blue tooth earpiece on. Then all at the same time my blue tooth shut down. My GPS shut down. And every warning lite came up in the car. Even the display that usually shows how the hybrid systems works was blinking problem!! Problem!! So I let off the gas and started to move to the rt side of the road. Thats when I realized that I had no power steering. There was an exit coming up so I let the car slow down to about 50mph. As I started to exit I put my ft on the brakes. Thats when I noticed that the pedal was very stiff and vibrating. I was coming to a blind intersection and I had the red lite. So I pushed on my brakes. Instantly I could hear screaching tires. So I looked in my side mirror. And to my suprise im looking at a large amount of smoke coming from me! My rear tires had locked up and my front tires werent doing anything. So I started fishtail back and forth like I had my ebrake on. I put all my wt on the pedal cause the intersection was really getting close. And without power steering it was very hard to keep the car from crashing. I came to a stop just before the light. Then drove my car to the nearest dealer at in berkeley ca at 10mph. I told them everything. Even about my blue tooth and garmin. They got me a rental car then 4day later they said if I give them $2000 for a part and $1000 in labor it might fix it but there not sure cause they never saw this problem before. And they werent going to pay for my rental cause the part was out of warrenty after 36000miles. I have had every svc done at toyota. And if theres a computer pt that toyota knows can brake easily. Which they do. Thats why its only warrenty to 36000miles. It shouldnt result in the loss of your brakes and power steering. Very dangerous!! I could of died.

While on a 3 hour trip across rt 40 from nashville to knoxville, my 2005 toyota prius unexpectedly accelerated three times. The first time it happened, it lasted a few seconds and then returned to normal. The second time it happened, I tapped the brakes to make it stop. The third time it happened, I applied the brakes but the car continued to accelerate to about 84 MPH (probably about 3 seconds) so I held down the power button and pulled off the highway. I do not use cruise control (because I don't like my car driving itself!!!). There were some scattered rain showers but the road was mostly dry. The car goes to the dealer tomorrow to replace an $818 heasdlight so they are going to check out the sudden accleration problem while it's there.
