Front and rear brake lines failed leaving me with no brakes. I was driving at low speed. The rear brake line was the first to go. The front burst and about 4 weeks later the cause was rust and corrosion. Both times the pedal went to the floor.
Brake line failed on rear brakes. Lost all fluid in motion on highway rust on brake lines
When driving my car over 5 miles it will choke and not let me accelerate and the speedometer goes to 0. Can you tell me what the problem could be?
The multi function switch does not work properly. When going around curves and corners you can't dim the headlights. Because the steering wheel doesn't allow the lever to go far enough to catch. Now my headlights will not turn on when the they are suppose to. My cruise control doesn't work. My A/C stops cooling when the speed reaches 60 MPH but if I move the m.f.s. (aka turn signal) it gets cool again for a few minutes. The other night my lights went off when I was meeting a car with its headlights on bright. It was a dark stretch of road. I almost ran in the ditch.
Headlights went off while driving on interstate at night. ( I may have flashed my high beams to signal a truck that it was safe to change lanes before this happened. Interior lights still working when this happened. Nothing I did would bring headlights back on. Very dangerous problem!! Car mileage approximately 62,000. 12/21/2017 date.
While in motion the high beam will go out and low beam with it - no lights at all. You must push or pull the turn signal lever to turn the lights on again.
Car stopped for no apparent reason while driving down the highway but started up immediately and continued driving home. Next week stopped again while driving as I pulled into the gas station but started up again and continued home. Next time driving no problems then stopped again while turning into the grocery store and again on way home while slowing down for a curve. Can't be trusted. Stops at 55 MPH on the highway. Very dangerous! One mechanic thinks it needs new engine computer because he pulled all sensors for testing and car continued to run.however, he is only guessing and won't guarantee a fix if I have new computer installed.
