Brakes blew out comming down a very steep hill. I was lucky because I had a Toyota in font of me slowing down because of a squirrel crossing the street. I had also slowed down but then the Toyota stopped and I went to stop my brake lines both front and back blew out and my peddal went to the floor and I had no brakes at all. Thanks to the Toyota being there to stop me other wise I would had a very bad crash into crossing traffic or head on into a guard rail or trees. I had to pay for all new brakelines installed on my truck and the damage to the Toyota and my truck costing around 2000. 00 dollars plus the insurance over 2300. 00 for the Toyota and my front end. Now im afraid to drive my truck.
I previously had to have the power steering cooler replaced because of leaking corroded lines. Just recently had to have trans cooler replaced because of leaking corroded lines. Mechanic said all lines underneath (brake, steering, etc) are terribly corroded and we will definitely pay attention to all corroded lines, etc in future oil change visits. The undercarriage of my truck is a corroded disaster. The rocker panels are gone. Corroded railer hitch was replaced. Luckily nothing has totally failed yet to cause an accident.
Speedometer acts all erratic, sometimes will show I am going 30 mph more then I really am, may sometimes show the needle being buried and not going over 20 mph actually, sometimes doesn't register at all, needle is jumpy, and at other times it will go back to normal for a few days without any incidents. This all started happening once my vehicle hit 51k miles. The dealership stated it may be the instrument cluster and could cost upwards of $1300 to replace.
