Vsa Warning Light On problems of the 2007 Toyota RAV4

2007 rav 4 had 3 lights turned on (check engine light, stability control light and 4 wheel drive light), shortly after the lights came on, the breaks failed. Rav4 was taken to Toyota delearship for repair and after the technicians being confused by the lights, they determined that the break booster had failed. This issue is similar to the recent highlinder recall and I feel people's safety is at stake with the breaks failing.

Check engine light, vehicle stability control (vsc) light & car slipping light on & off while driving. Toyota dealer replaced oxy sensor & vsc computer, but still happens. Toyota doesn't have an answer. Vsc seem to work when lights are off, but understand that won't work when lights are on. Seems to be a problem with these vehicles as I've seem many complaints & questions from other vehicle owners on internet. Not having vsc working is great cause for concern in an SUV as SUV may roll causing injuries/death. Thank you.

When driving for longs periods, and some short periods including coming home from the dealer when the vehicle was brand new, the check engine, stability control, and 4wd lights come on in the cluster. The cruise control, 4wd, and stability control do not function when this happens. The dealer claims they could not find any codes and cannot fix it. This has been going on since March of 2007, and the warranty has expired. I feel this is a huge safety concern, as I have heard of other Toyota vehicles doing the same thing, and stability control is a safety feature.
