| Cheap thin black plastic engine cover for oil pan is defective with one edge cracked 100% after only 5 oil changes similar to aircraft aluminum metal fatigue. this plastic flap under oil drain plug is now dragging on the road hanging by a single bolt. ridiculous to fail after opening and closing oil drain pan cover 5 times. we view this as a defect covered under our bumper to bumper 7 year 100,000 mile platinum extended warranty contract for which we paid $1870 on 07-14-2009 for a new vehicle. minor scratches and dust are not proximate cause of failure. | |||

| Second occurrence of this problem iin three weeks. driving downhill on a residential street at 25 mph, slowing to a stop without applying the accelerator. suddenly lost engine power. applied accelerator, no response. continued to lose speed as i rolled silently downhilll toward the intersection. applied brakes and stopped. restarted the engine and it started up fine. the previous incident also occurred on a downhilll grade, on an exit ramp from an parking garage. fortunately both incidents happened at low speed and not in heavy traffic. i previously reported the first incident. toyota dealer checked vehicle after each incident and could not replicate the incident or find a computer code that would explain it. since this was the second occurrence and was familiar to me, and since i was not in traffic, i let it happen while observing my own actions, trying to check for driver error. my foot was not on the brake.the car was in drive. while the car was slowing, i tried pressing the accelerator deeply and then pumping the accelerator to see what would happen.. there was no response, and no sound. the same was true three weeks ago-no response to pushing the accelerator, eveb deeply, and no sound. three weeks ago, the first time it happened, i also tried cyclying through the modes (ev, prius, eco, power) with no effect. each time, i hit the power button to power off, and then i hit it again to restart. powering off and then restarting, both times, seemed like rebooting a computer. fortunately traffic conditions both times gave me ample time to reboot. will this happen again? | |||

| Exiting from a parking garage. after passing through the pay line, i headed down the exit ramp toward the street. the vehicle refused to accelerate as i pushed on the accelerator. . it did very slowly accelerate to 11 mph and then started to decelerate. i stopped the car on the ramp, turned the engine off and restarted it. after that, everything was fine, and i was able to drive home. . if this had happened while i was trying to merge into traffic. it would have been hazardous. | |||

| Access to the oil drain plug and oil filter is through a plastic doorway opening under the engine compartment. the doorway is a partial cutout from a larger plastic shield which encompasses the entire front portion of the car. i performed my 3rd oil change and during this preparation i found that the door portion of the shield is broken away from the larger piece of plastic due to bending/hinging the door. only after 2 oil changes this plastic door has broken off because the plastic is not designed to be repeatedly bent from open to close more than once. unless you change your own oil, you will never see this door break off... and after 2 oil changes. *tr | |||

| I travel quite a bit these days and on my way home from coachella music festival, my brakes gave out. i mean to say, pushing the pedal all the way down, no resistance, no slowing, a completely limp pedal....until i repeatedly stomped on it and the car locked and skidded to a stop, feet away from the car in front of me. the brakes returned intermittently, so i took the right hand lane at 40mph and tested the brakes regularly until i got to my dealership. scariest thing ive ever experienced. ive had the car since august 09' and currently have 43k miles on it. i know thats a lot, and its unfortunately outside of my warranty now, but i wanted to log it here, as soon as i could. it started one day before the freeway incident, whenever i would depress the pedal, a loud high pitched squeak would come out. i didnt think much of it outside of better get that looked at but didnt notice any brake failure. the next morning, i turned on the car and every dashboard light came on and a fast consistant beeping went on for about 5 minutes, during which time the brake pedal had zero resistance. i sat there with a serious wtf look on my face, when out of nowhere, the dash lights went away, as did the beeping, and the car drove as normal with full regular brake pressure (besides the squeak). i received a call back from the dealership. they say it's going to be $3k for a master cylinder replacement and that toyota corporate wouldn't aid in the cost, despite my hybrid warranty still covering the hybrid ecu (the master cylinder unit includes the ecu). margaret (my dealership service manager) said herself that it was not my fault and that the part is not repairable, it either works, or it does not. it must be replaced. this could have been catastrophic, had i been any closer to the car in front of me. the failure of one part (which failed through no fault of the customer) rendering the brakes nearly useless is too scary not to report here. thank you david del fonzo | |||

| After car sits for several days engine will idle very roughly upon starting for almost one minute. idle is so rough that i thought the engine mounts would break and creates a very very loud rattling sound. this has happened three times, two after sitting for several days and once after just sitting overnight. | |||

| 2010 toyota prius. the consumer stated he experienced two safety issues; loss of brake effectiveness and engine race *tgw when the consumer applied the brakes when going over bumps/rough roads, or in marginal conditions due to snow/ice when approaching a stop sign, he would lose braking effectiveness. the consumer took the vehicle to the dealer for a recall repair on march 24, 2010. however, he continued to experience loss of brake effectiveness. the consumer pulled into a neighbor's driveway after driving less than one mile from his home. after pushing the park button, but before pushing the power button, the engine began to race. it was not at an extreme high rpm and it was not for an extended period time, but it did last for several seconds. after the vehicle went down to normal rpm, after a s second or two, it began all over again. the consumer stated it was not a surge as the vehicle was not in gear at the time. *jb | |||

| 2010 prius ii - when in park, or just slightly on the brakes and the engine switches from electronic to gas motor, the car rocks forward 1-3 inches. very terrifying, but according to kendall toyota of eugene, oregon, this is normal. i don' t know of any world in which a car moving on its own while in park is normal. | |||
