Ignition Module Problems of Toyota 4Runner

Warning lights began coming on around 60,000 miles or so. Started with the low tire pressure light & now has progressed to the vsc on, vsc off, abs warning lights being on all the time and the low tire pressure light is still on. I have taken this vehicle into 2 different dealers to be fixed for 40,000 miles or around 3 years which amounts to multiple trips to the dealer, waiting while they work on it or going without a vehicle for days at a time while they try to figure out what is wrong. They have replaced abs sensors, engine computers, brakes, speed sensor wires, reset computers, ordered new valve stems for the tires. I can get online & find thousands of complaints regarding the same issue in Toyotas & Lexus vehicles since at least 2001. The dealerships look at me like I am the very first & only person to ever mention these problems. The solutions online have ranged from defective master cylinder/brake booster assembly, faulty ignition coil, O2 sensors, vsc computers, catalytic converters & brake pedal switches. Also problems with the exhaust system & acceleration module under the console was listed as fixing these issues. Why has this issue not been addressed and/or fixed in 8 years ? there have been times when my brakes did not work, times when they barely worked, times when I put the brakes on & it abruptly pulls to the left or right & a couple of times when my vehicle would not accelerate as I was pulling across traffic. As I read of these "freak" accidents lately with Toyotas, I have to wonder if they really are "freak accidents". I do not want my family or myself to be one of the Toyota fatalities this year or anytime. When is something going to be done ? how many more innocent people have to die ?.

This truck (auto, 6 cyl, 2wd) sometimes stalls, but only when coming to a stop, always in motion, never at idle, just as if the key were turned off. Occurs very intermittently (7 times since sept 2003). . . Mechanic informed me that nothing has registered on the computer. Interstate battery is 8 months old. Every other time, I've put it in park and it starts right up, but this morning it wouldn't start for almost two minutes in a busy intersection. A friend also has 1998 4runner; says it's been happening to her over two years, but less often. This is very dangerous. This can't be a coincidence, and it can't just be the two of us. I spoke with Toyota today, but mine is the only complaint they have about this.

Engine failed while driving on the highway at normal speed. Dealer couldn't find anything wrong. Truck continued to fail and not start for another week until it was towed to dealer again. Second dealer claims ecu is rusted caused by a leak somewhere. Truck purchased 4 months ago and was a certified used veh. Toyota will not pay for the fix. Nlm.
