general problems of the 2007 Toyota FJ Cruiser - part 2

I experienced braking failure while driving in wet conditions with melting snow in town at speeds from 0 to 30 mph. Brakes felt extremely mushy and vehicle only slowed by applying extraordinary pressure to brake pedal. At stop, pedal continued to depress all the way to floor and despite standing on brake, vehicle continued to creep forward. I am 6' 1" tall and over 190 pounds, depressing the pedal as hard as I could, completely standing on pedal, I could not keep this vehicle from moving ahead. I believe if this vehicle had been being driven by a shorter, lighter person, the potential for a serious accident would have been greatly increased. Vehicle exhibited same failure two or three more times while driving home (total of 5 mile trip). Next day inspected fluid reservoir, lines and hubs for any fluid. Reservoir was at proper level and no sign of any leakage. Since that isolated incident vehicle brakes have performed appropriately.

The first incidence occurred in December 2009. There were patches of icy snow along our street. I was approaching a stop sign (the speed limit is 25 mph) and applied the brakes. I applied the brakes sooner than what I would have normally due to the road conditions. As I applied the brakes, the front right wheel made contact with a patch of icy snow. Much to my surprise, it was as if I had not applied any brakes at all, and my Fj Cruiser continued through the intersection which entered onto a main thoroughfare. There was no braking action and it was as if I had never put my foot on the brake. I really thought I was going to go through the intersection and be hit broadside and started to prepare for an accident. Fortunately, I released and reapplied brake pressure, and my Fj Cruiser came to a stop. Since this was the first braking incident I passed it off due to the snowy conditions of the road. The second incident happened again in December 2009. I was on a street that was under heavy construction and there was a lot of loose gravel on the road. I was driving approximately 25 to 30 mph. This time when I applied the brakes, I experienced the opposite effect. The brakes locked up and actually skidded to a stop as if I had applied the brakes in a panic situation (like I was going to rear-end the car in front of me). The third braking incident happened in January 2010. While driving in our neighborhood (the speed limit is 25 mph), I approached the stop sign and applied the brakes. As I applied the brakes the front right wheel contacted a patch of icy snow. Again, it was as if I had not applied the brakes at all, and my Fj Cruiser continued through the intersection as if I had never put my foot on the brake. Fortunately, there was not any traffic as I slid through the intersection. I released and reapplied brake pressure and my Fj Cruiser came to a stop.

1. The 'unresponsive' issue - this seems to happen when braking at low speeds (under 40mph) and one side of the vehicle hits a pothole, uneven pavement, or loose gravel. The result is that the brakes become momentarily unresponsive until you release and pump the brake pedal again. It definitely feels like the brake electronics/software are confused and get caught in a momentary glitch as it figures out what to do. 2. The 'overresponsive' issue - this seems to happen under very similar conditions to the other issue - I. E. , low speed braking over uneven or broken pavement. The result is that the brakes become super sensitive to the point that normal braking flings you and your passengers hard into to your seatbelt restraints, as if you are slamming on your brakes. The brake pedal gets a little mushy and then wham. . . The brakes kick in big time. I am pretty sure that this condition is created by the brake assist function.

After reading that this department was "opening a formal investigation of the Toyota prius hybrid model year 2010 to look into allegations of momentary loss of braking capability while traveling over an uneven road surface, pothole or bump", I realized that this exactly describes my experience on several occasions with my 2007 Toyota Fj Cruiser. I did not report this to the dealership. I thought it was my fault for my speed when hitting the uneven surface. I don't know really why I didn't ask about this but this definitely happened on more than one occasion.

While operating a 2007 Toyota fj (59,956 miles) all the instrument panel indicator lights came on and the brake pedal felt as if it went to the floor. You would practically have to stand on the brake pedal to get the brakes to function. For some drivers, it would be easy to assume that the brakes went out completely. This loss of brakes could have led to an accident. Fortunately, it did not. Taking the vehicle to the Toyota dealer for service, it was determined that the abs hydraulic booster, part number 4705035052, had malfunctioned. Obviously, this is a critical component. It is also a costly part at $2,145. 99, plus labor.

Unresponsive brakes when going over potholes . Overly sensitive brakes at low speed .

My 2007 Toyota Fj Cruiser has a definite and very serious brake problem! on at least 6 to 8 occasions brakes have locked up and caused temporary loss of control of the vehicle! on some occasions, I feel that a less-experienced driver could have crashed!! one occasion was at 55 mph while passing another vehicle. This occasional scary experience has been reported by numerous owners of this vehicle on the Fj Cruiser forum, but this dangerous condition is not being addressed by Toyota!!! help!!!!!.

The 2007 Toyota Fj Cruiser has a similar if not the same braking issue as the prius. If the vehicle hits a bump, pothole etc while actively braking the brakes stop working until the brake pedal is completely let off and reapplied. Almost caused several accidents in my case.

The contact owns a 2007 Toyota Fj Cruiser. The contact stated that whenever he is driving in reverse downhill, the brakes release. Both the dealer and the manufacturer stated that the braking system was within the necessary parameter regulations. The failure has not been diagnosed. The VIN and speed were unknown. The current mileage was 9,090 and failure mileage was 1,000. Updated 05/05/08 updated 05/05/08.

The contact owns a 2007 Toyota Fj Cruiser. When coming to stop the contact drove over a pot hole and when applying the brakes the vehicle did not stop and began to lunge forward. The brake pedal extended to the floor and the contact had to release her foot so that the pedal will release; otherwise, she had to pull it up manually. The vehicle was taken to the dealer where they stated that there was nothing wrong with the vehicle and they could not duplicate the problem. The failure occurred five additional times and was taken to the dealer five times as well. The contact replaced the brake pad and rotors which did not resolve the failure. The failure mileage was 29000 and the current mileage was 75000.
