This has been an issue since acquiring this vehicle. The brakes are very soft, they will pump up but when a quicker slow down or stop is needed an individual doesn't have a lot of time to remember that. There have been no injuries or crashes as of this date. Master cylinder was replaced on mechanic's advice however this did not improve this issue. As well the vehicle seems to need the lower ball joints wear out quickly. Also please note that each time it rains there is water coming in from somewhere on the top driver's side of the windshield and post. It drips from that hand grip down to light switch and into vent on driver's side as well. There have been times where there is an electrical smell which causes concern of a vehicle fire possibility.
Parked vehicle at store and turned it off got out and went inside. Then someone came inside and said that a black SUV was on fire. Returned to car and hurried and opened the hood. Had a drink in the truck so got it and threw it on the fire got it put out and looked it had started at the master cylinder and cruise control sensor.
