problem #186

Jan 062017


  • 90,000 miles


My dashboard went darking including the speedometer and it appears to also disable the odometer when this happens. This happened after stopping to fill up for gas. After restarting the car the dashboard will no longer light up. It looks like you can temporally reset the faulty part by disconnecting it from the battery and reconnecting it. This issue is regarding a problem that is known to Toyota, they have extended the warranty for this part to 9 years/unlimited miles. My Prius was effected after 9 1/2 years putting me past the warranty they extended. The problem is with the "combination meter", it appears to be caused by a bad solder during the manufacturing process. Research shows me this effects 2004-2009 Prius models and it looks like most Prius will run into the issue at some point. I'm not sure why this hasn't been a recall as no speedometer is obviously a safety issue, the problem is widespread and Toyota seems to acknowledge the problem with their warranty extension. I imagine it took me more than nine years as we only have 90,000 miles after nearly 10 years of ownership. A google search on Toyota Prius combination meter problem will bring up a lot of information on this. Thank you for your time, mike holiday counsoul23@hotmail.com

The rubber cover of the rear lift gate switch has deteriorated to the point where the switch won't work any more. I am unable to access the spare tire and other important things in the back of the car.

While I was driving, the car suddenly made a very loud sound, that did not go away. Along with that, the lights on the dash lit up, the brake light, the red hazard exclamation triangle light, the ABS and vsc light. It felt the brakes were not working and I would need to press it down hard for it to slow down. This has happened three times! and each time I took it in to Toyota, their diagnostic tests showed nothing. They think it could be the battery but they did not suggest changing it. The three episodes that happened, luckily no injuries or crashes. But it is very concerning as I feel this will happen again and they have not figured out what the problem is.

This 07 Toyota Prius dash instrument lights will go out whether stationary or in motion and or not come on at the start of the vehicle. The car can be driven but there is no way to reference the speed or vital functions of the vehicle when this occurs. Also the vehicle will not turn off when the power button is pushed when the dash is inoperative unless you hold the power button down for an extended amount of time. Toyota knows about this issue but the time limit on the unpublished extended warranty that I was told has expired. We bought this vehicle new in 07.this vehicle started doing this recently. This should have been a recall item on this vehicle due to the potential safety issue.

As I was coming back from livermore to san jose down the sunol grande last weekend, my dash lights suddenly went out meaning I had no speedometer or wait to tell how much gas I had and the ABS and stability control went out while going 65 miles an hour down a steep hill.luckily I was able to get home and don't ask me how I figured out to get the car to turn off. I called the one 800 Toyota number and it turns out there was a problem with something called the combo meter on these cars and it had an extended warranty for a total of nine years. My warranty expired they said April 2016. This seems like a serious safety issue that Toyota should cover if they are concerned about their customers safety.

Driving on a rainy day, ABS and vsc lights on dash came on. My car violently fishtailed almost 180 degrees, back and forth 6 times on a curve getting off a freeway (about 45 mph) nearly crashed. I proceeded very slowly to side street. Car shimmied to right making a left turn. Felt like I was driving on ice. Called a tow truck. Dealership found rodent damage to wires to wheel speed sensor. I discovered manufacturers using soy oil on wiring. $1300 repair.

Takata recall. My car won't shut off. They say the instrument panel cluster needs replaced. It has been on back order for 13 days so my car is useless. I can't drive it. I paid either 23,000 or 28,000 for it and have kept it maintained. The Toyota place says they have another lady that's been waiting 3 days less than mine. I called California Toyota. They can't tell me anything - but today told me it might be on back order. This is a safety issue. A car that won't shut off is a danger. It could kick into gear. It could damage the motor. A car that you can't tell how much gas is in it can be a problem as well. I can't drive it. The speedometer won't work. This is a problem with safety as if you can't tell what speed you are going you risk tickets. The Toyota place in birmingham has replaced 30 of these instrument clusters. If that is representative nationwide there is a big problem and these cars should be recalled. I only have 150,000 miles approx. On my car. The salesman told me it would last at least 300,000 miles. I had to replace the $4800 battery at 103000 miles. My other gripe is they didn't tell me until 13 days later it was "probably" on back order. I wouldn't have rented a car for 13 days had I known it was "probably" on back order.

The trunk opener switch on my 2007 Prius no longer works reliably because it is made of a defective rubber which has at this point melted into a goopy mess. This means that the opener switch can become stuck in the closed position, rendering it impossible to open the trunk until the release mechanism of the switch overcomes the tensile strength of the goop. As a cursory google search shows, this is a common problem which Toyota routinely refuses to repair. It is a potential safety issue because a pet or child could be difficult to retrieve from the trunk area if the trunk cannot be opened. An unexpected hazard such as a leaking propane tank or a battery fire in the trunk area could similarly be difficult to mitigate.

The electronic dash (heads up instrument display) on our 2007 Prius has intermittently failed to light over the last year. Yesterday, it failed and also wouldn't turn off. We always use the remote (keyless) ignition system. But, after the failures yesterday I put the electronic key fob into the hole in the dash thinking that might help. Instead, I couldn't remove it. I tried every combination of pressing buttons (the park and power buttons) and other controls, brakes pedal, shifter and it still wouldn't shut off or light up the display. After holding the power button in for an extended amount of time, it turned off and ejected the key fob. But then the car wouldn't light up the instrument display or start. This morning, again, it would not start. I was told by an experienced Prius mechanic (also an owner) that these were classic symptoms of a failing power amplifier for the display and that it was a "secret warranty, " a voluntary repair to avoid a government recall, but that Toyota would only do it for 10 years. The dealer refused to do it under warranty even though the symptoms began before the car was 10 years old. They told me the recall was only good for nine years. They want $765 for the repair. It strikes me that this is a safety failure and should be covered, period. With no indication of speed or other functions (ABS function, traction control, etc.), or to turn the vehicle off, it is unsafe to operate the vehicle. The various failures, including loss of cruise control while in motion, took place when the car was cold and when it was warmed up. At rest and in motion.

The contact owns a 2007 Toyota Prius. Without warning, the instrument panel cluster failed and the gauges failed to properly function. The vehicle was taken to a dealer to be diagnosed. The manufacturer was notified of the failure and indicated that the time frame had expired for the contact to receive the warranty extension campaign and provided no remedy solution. The approximate failure mileage was 115,000.

The headlights on my Prius randomly go dark. Sometimes 1 headlight and other times both. Turning off the light switch and then back on is a temporary fix. The problem comes back minutes later. This is very unsafe for myself and other drivers on the road. This happened while I was on the interstate going 70 mph last night!

My wifes 2007 Prius headlights continue to flicker while driving at night. Then one side or the other will go out. The headlights have been inspected by 2 certified mechanics neither can find any faults in the headlights or bulbs even applying contact grease to assure electrical continuity. Attention NHTSA administrators ( this certainly could become a deadly problem.) we have had both lights go out simultaneously. The driver must immediately turn the light switch off then on to restore lighting. I hope they never fail to re-light!! of all the problems- attention surely must be given to these lights. Almost a thousand complaints here..how many people keep taking this problem to the dealers, only to have it repeat itself? immediate action is required by the NHTSA.
