2007 Toyota Prius: transmission slipping

Filed Apr 30, 2019 · Brakes · 106,000 miles · MT

Front wheels loose all traction on icy patch! Traveling north on an old paved country road with a moderate crown and narrow lanes, I came upon a modest bluff that was just abrupt enough to keep me from seeing the road surface on the other side. Within 50' of the other side was blowing snow, some sticking and turning into ice. Air temp. 27 degrees. Don't know the surface temp, and it was sunny, nice. This patch was 500' or so and prompted me to remove my foot from accelerator. I was approaching 50 MPH, not fast for this road and was in no hurry. Within the time of a breath, my front end blew smoothly toward the ditch and me and the prius came to rest within 30' or so. Now this light to moderate cross wind took control of the front of the car, 'not the back'. The point being, rear wheels are free spinning, while front wheels have a rather aggressive breaking effect. Mind you, never considered touching the 'breaks'. In addition, I've learned that driving on snow covered town streets, that it is best to pop the car into neutral when approaching an intersection and applying the service brakes, this action would prevent the car slipping or sliding at all. (3 mo. Old michelin defender tires) not dedicated snow tires, but in my experience, very good. This town I live in has very steep grades, I'm able to negotiate all of it coming and going. I believe this incident (state farm claim #[xxx]) was caused by the overly aggressive regenerative breaking action when removing ones foot from the accelerator. Additionally, I would like point out that a hour earlier while driving to my destination, I'd driven over many drifting patches at varying speeds from 50 to 70 MPH with a stiffer cross wind. However I could see them far in advance. After a lengthy go-a-round with toyota over the phone, the response was, they will take no action on this car or in the future models. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

The vehicle traveled over an 18 inch snow bank and crashed into a tree. The front and rear bumpers were damaged. There were no injuries. The vehicle was driven to the dealer. A representative from the manufacturer performed a diagnostic test and found that the gear shift being placed in and out of park several times caused the gears to slip into neutral and then into reverse. The contact confirmed that the vehicle was in park. The contact was not offered any assistance with the repair. The failure mileage was 44,000.

When braking, the vehicle seems to momentarily accelerate when going over puddles, bumps, grooves or train tracks. This can happen repeatedly on wet or gravel roads... Vehicle has slid off a gravel road and sideways going over traintracks when the brake slipping occurs. The anti-slip regulator light goes on when this happens.

2007 toyota prius. I noticed brakes slipping or delayed engagement very soon after purchase. When the brake hesitates the slippery road icon always comes on. I took the car into the dealer 3 times within the first 12-18 mos. They kept it overnight and had the tech drive it without the problem occurring for him. Since the warranty expired I have decided to live with the problem. I since purchased new tires which has decreased the frequency of the brake hesitation. Now I fear serious brake failure. I called the dealer dave white of toledo, ohio today and was told by the service dept.to wait for a letter re. The brake and accelerator problems which should arrive in about a month. I am concerned about the safety of my car in the interim. Actions to date have done much to heighten awareness of problems but have done nothing to increase safety in the short term. I hope that the federal safety agency will address this issue.

2007 toyota prius - brakes if driving over a pot hole, bump, or any other non-flat surface, the brakes do not work, the car thrusts forward, & the "ABS" light flashes. This is likely the cause of an accident I had slipping off the road approximately a year and a half ago.

I had a 2007 toyota prius that seemed to have issues whenever I would hit the brakes on slick\wet roads or sometimes when I would hit a bump. It felt as if the brakes would not apply and the car would feel like it accelerated forward instead of stopping. Usually the brakes would kick in after a second or two of this kind of slipping. However, in early november of this year while taking my son to karate on a wet day we hit a spot of repaired road that caused this to occur again, instead of correcting itself it felt like I had no control of the car and the car veered off to the side of the road, went up an incline and flipped the car onto its side. Fortunately in this case no one was injured at all as I was going fairly slow and the car quickly came to a stop when it went on it side. I always thought the issue was with the anti-lock brake system but I recently saw an article about 2010 prius having this issue and I thought I should report that this happened to me on an older version of the prius as well.
