Brake Sensor problems of the 2007 Toyota RAV4

The dealer said that the sensors behind my breaks were defective. My abs and cruise control does not work. This has been an ongoing problem since I purchased the car. Can you help. The deal said it is not a safety issue because I can use my brakes the old fashion way by pumping them. Abs does not work. What can I do. Toyota said this is a common problem with the rave4.

On March 21st the abs, vsc, traction and break warning lights came on while driving at 35 mph in dry weather condition. When the lights were on, the abs system was triggered making difficult to break to stop. Since then the warning lights have been on and off and so I've been having difficulties when slowing down at a higher speed rate 60 mph, slow speed 20 mph, and even stopping. On Tuesday, April 8 I brought the Rav4 to the dealer and they said that there is nothing wrong with the car and that the breaks were ok. Dealer said: it is just the a rear sensor that needs to be reset. So dealer technician reset the sensor the same day. On Wednesday, April 9, 2014 around 6:00 pm when turning left at a corner I heard a ticking noise then four warning lights appeared again and the breaks started to malfunction again. I'll bring the Rav4 to the dealer on April 12, 2014 and see what they have to say. The codes the dealer have initially were c0210 and c1223. My spouse and I don't want to drive the Rav4 without knowing that the sensor that the dealer talks about is either fixed or replaced. I don't want to be exposed nor expose my family to any possible accident due to the sensor/breaking system failure.

The contact owns a 2007 Toyota rav 4. The contact stated that while driving 45 mph, the check engine warning light illuminated. The vehicle was taken to the dealer who diagnosed that the posterior oxygen sensor was defective and needed to be replaced. Two days later, the check engine light was illuminated again and the contact experienced brake failure. The vehicle was taken back to the dealer who diagnosed that the brake booster needed to be replaced. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure and current mileage was 27,000. Updated 11/03/11.

Last night, my Rav4 battery died due presumably to the rear door light getting accidentally turned on. Upon jump starting the car, everything seemed fine. I drove it home without incident. Then, this morning, the battery was not quite up high enough to start the car, so I jump started it again. It started, but a few hundred feet away, I lost power steering and power brake assist. It required every ounce of force I could muster to turn the vehicle around and get it back to my house. Thankfully, this happened on city streets near my house and not on the highway last night or the chp would have been scraping me off a bridge post. The Rav4 cannot realistically be steered by an average person without the power steering assist because of the gearing ratio, making this a very serious design defect. If a vehicle cannot safely operate, the vehicle should not operate. The problem is that, because the battery plays an integral role in power smoothing, and because the power steering and power brake pumps are electrically operated, a low battery can result in failure of the power steering and brake pumps while the engine is still functional. This can easily result in an uncontrollable vehicle barreling down the highway at 80 mph. I believe that fixing this problem requires a fundamental redesign of the electrically operated pumps to add additional capacitors so that the battery is not playing such a crucial role in smoothing out the pulsating DC from the alternator along with the addition of sensor hardware to detect a low battery condition and activate an indicator light until the vehicle is safe to drive. Ideally, the steering gearbox should also be redesigned with a lower gear ratio so that it does not become undriveable. Without these fixes, the 2007 Rav4 is fundamentally unsafe. This design flaw probably also affects most other late models of Toyota.
