tl* the contact owns a 2007 toyota prius. the contact received notification of nhtsa campaign number: 12v536000 (engine and engine cooling, hybrid propulsion system). the vehicle was taken to an independent mechanic where it was diagnosed that the water pump needed to be repaired. the contact stated that the water pump was repaired previously under a manufacturer's recall. the manufacturer was notified of the failure. the approximate failure mileage was 121,568.

Toyota has failed to recall the electric water pump in the second generation prius. toyota has recalled the first generation prius for a faulty electrical water pump, which is the same pump found in the second generation. while driving home from work, my check engine light turned on and i had to go to the toyota service to get it checked. after being told that it was recalled on the first generation, i looked up information online on if this was the same water pump. i then came across numerous articles and recalls on other toyota websites (in different countries) stating that the pump has been recalled. toyota however has not recalled any of these cars in the usa. *tr

I have recently moved to pennsylvania, a state with many hills, and have found that on icy hills, the traction control causes the engine to shut down entirely when the wheels slip. this creates a very dangerous situation where there is no power at all to the wheels, causing the car to slip backward on the ice. i live on a steep hill and my car has almost rolled off the hill three times due to the failure of the traction control / engine. the prius, unlike many other cars with traction control, has no traction control shutdown/override switch. in researching this online, many other owners report the same problem. toyota refuses to acknowledge that there is a problem. this is very dangerous.

I have a 2007 toyota prius that is approaching 36,000 miles soon. its brakes stutter when i try to come to a smooth stop. its engine also vibrates excessively as if its misfiring, when idling. the symptoms do not happen all the time, but they happen frequently. i have taken the car to the local dealership several times, but they have not been able to fix the problems permanently. after my most recent visit to the dealer, they claimed they could not replicate the brake stutter symptoms and that the car\'s computer had no record of it misfiring. if you do a google search on the internet about "2007 prius brake stutter problems", it appears to have happened to many other people. please help. i want the problem fixed, or the vehicle replaced. there has been no physical damage nor crashes nor injuries. however, i am concerned that such symptoms detract from the value of the automobile, or at worst may result in an actual crash and injuries later on. the symptoms are a distraction and annoyance while driving. *tr

Was driving at 30mph in residential area. no prior warnings of failure. 1. car turned off - not the power but the ability to drive or put in gear or run. car was non-drivable or movable in any way for next 3 hours. 2. never happened before, problem unknown as the car works perfectly. 3. dealer said they had no explanation toyota prius 2007 stalled and would not start - had car towed to dealer and problem disappeared after 12 hours. they had no explanation. *tr

Tl* the contact owns a 2007 toyota prius. the contact stated that while driving approximately 55 mph the vehicle started to overheat. the check engine light illuminated on the instrument panel prior to the failure. the vehicle was taken to a dealer nearby and they advised him that they needed to replace the inverter pump. the vehicle was repaired for the inverter and water pump. the failure mileage was approximately 96,400.

2007 prius (69k miles). driving on highway, all caution lights came on. towed to dealer and diagnosed with a 12-volt battery issue. $280 to replace the batter. three weeks later, same cautions lights. got most to clear with a restart with the exception of the "master caution" and the "engine check" lights. dealer showed code of "p0a93" and stated inverter coolant pump needed to be replaced for another $486. check online shows toyota knows about the pre-2006 issues and that many 2007 and beyond owners are running into the same issue at various miles. *tr

I own a 2007 prius with 35,000 miles on it. we have been a 2 prius family for 6 years, so i am highly familiar with driving one. i have had three very frightening incidents happen in about the last 4 months in my car. each has happened in exactly the same spot during a commute that i do several times a week. i have been exiting from a freeway, going 65 mph, down a gentle downslope. when i exit (continuing the downslope) the engine starts revving at a speed that i never have heard during any normal driving circumstance. this is while i am braking to stop at a light at the bottom of the exit. i have had a car next to me roll down the window and the driver ask if i needed help. over the last 15 years i had done this exact exit thousands of times, in many different vehicles, and have never experienced anything remotely like this. each of the three times i shifted the car into neutral, but the high rev continued. the only thing that stopped it was to pull over and to turn the car off and restart. i immediately checked the floor mat each time and it was mounted securely exactly in place hooked on the mounts. this has happened three times, completely randomly. i took the car in to be serviced at toyota of berkeley on 2/2/10 and was told that until the car did this on a "frequent" basis that there was nothing that toyota could do. he checked the log for warning lights and there were no entries (i checked the dash each time this has happened, and no lights warning lights were on.) *tr

Coolant system has air in it. service failed to diagnose the problem. service campaign issued for other vins, but not mine. *tr

Tl*the contact owns a 2007 toyota prius. the contact stated that whenever the front wheels began to spin in icy or snowy conditions, the engine completely shut off. the failure occurred multiple times while trying to drive up a hill or an inclined driveway. the dealer inspected the fuel injection system on several occasions and was unable to find the cause of the failure. the manufacturer stated that the vehicle was designed in such a way that the engine would turn off to avoid damaging the stability control system. the vehicle has not been repaired. the current mileage was approximately 36,000. the failure mileage was approximately 2,000. updated 3/16/10 *cn updated 06/29/10

Tl*the contact owns a 2007 toyota prius. while driving at various speeds and making a left turn he could feel the tires slipping. the vehicle begin to stall intermittently including when the contact made a left turn. the contact has not driven the vehicle since the vehicle could stall and cause a crash to occur. the contact advised the dealer during a routine oil change on several occasions; however, he was advised that the malfunction is due to the design of the vehicle. the vehicle has not been repaired and has been inoperable for two months. the failure and current mileages were 3500.

date: 02/09/2010 time: 10:01:20 creation date: 02/09/2010 creation time: 09:58:43 i would like to report a braking/traction control/loss of engine power safety problem with my 2007 toyota prius. the problem happens while driving on snow covered flat road surfaces (1 inch of snow), snow covered hilly roads (1 inch of snow), and bumpy road surfaces. when the traction control system (trac) engages on these road surfaces, i lose the ability to brake and also lose power to the engine simultaneously. i have had four (4) near-accidents due to this safety problem. 1.snow covered (1 inch of snow) going downhill (slight hill)- lost brakes after trac traction control system engaged was unable to stop car - went through stop sign. car went onto busy highway (50 mph zone) and would not stop. luckily no cars were coming and i avoided a very serious accident. 2. snow covered (1 inch of snow) going downhill - lost brakes after trac traction control system engaged and almost crashed into cars that were slowing down ahead of me. 3. snow covered (1 inch of snow) going uphill - trac traction control system engaged and i lost all engine power as i was turning left up a steep hill. i almost crashed into large rocks at the roadside. i was able to avoid a crash. 4. snow covered (1 inch of snow) driving on flat road surface. i turned off of snow covered road into a parking lot area. trac traction control system engaged and i lost the ability to brake. my car went at least 15 feet in the parking lot area before stopping. luckily there were no parked cars there and i did not have an accident. a recurring problem with trac and loss of engine power also occurs on the hilly road leading up to my house. when the road is snow covered (1 inch of snow) or icy the trac traction control system engages and i lose all power to the engine. it makes it nearly impossible to get my car up the hill due to the loss of power when trac engages! *tr

My 2007 toyota prius stalled without warning in heavy freeway traffic on a bridge with no shoulder. the wa state d.o.t. pushed me to safety. again, my 2007 prius stalled without warning in freeway traffic!!!!!! *tr

Tl*the contact owns a 2007 toyota prius. when switching from cruise control to applying the brakes and back to cruise control, the engine revved for no apparent reason. the failure usually occurred when the contact applied the brakes rapidly and transitioned back to the cruise control while driving 25 mph. the vin, engine size, number of cylinders, and powertrain were unknown. the current mileage was 7,500 and failure mileage was 6,500.

Indicator lights flashed. malfunction indicator lamp stayed on. at 2,644 miles, 12 v. battery dead & replaced. i was told to keep the gas tank half or a quarter full or the reserve gas tank would cause the car to run on battery. the battery might have died because the car sat too long before it was sold/at 8,879 miles, i went in. after filling the gas tank & taking out the nozzle, gas spewed & bubbled out. the car stalled while driving slowly & while in park. indicator lights flashed. the malfunction indicator lamp and master warning lights stayed on. it took 5 min. to turn off the car. i started the car. those lights stayed on. i was told i left the "trunk door" open & ran down the battery. (not true.) there is a gasket around the access hole and if a person "is a little bit off," the gas will regurgitate. (i was not " off" & did not top off the tank.) they reprogrammed the computer. the gas tank had not been filled so i knew they did not fill the gas tank and try to recreate the situation as they said they would. i bought gas at a different pump. i stopped at a stop light. i could feel a loss of power in the car. when i pushed the gas pedal, the car would not move. i turned the car off and on 3 times before it would move. it crept slowly through the intersection as the traffic signal turned red. i took the car in at 8,936 miles. i was told if my problem is associated with the battery that was taken out of my car, it is not at repair person's responsibility because he did not touch my battery. when a battery is disconnected for a certain amount of time, if something is not reset, it could cause problems. then, he said no trouble found/my car stalled and/or had a loss of power. i took it in at 9,014 miles. no trouble found. i was told that my problems could have been caused by a faulty gas pump overfilling my tank. the gas station is new. the manager said the pumps were inspected. ...
