In owners' own words
The vehicle will lose power to the brakes while driving intermittently. When problem occurs you will lose power steering and pressure to braking system. Also the driver hid headlamp gets moisture in it whenever it rains. I have had to replace the hid bulb about 6 times in the past year. Also there seems to be an electrical issue with the onboard computer that causes the tachometer to not work or read correctly. Service brakes · reported at 155,000 miles
While driving my 2005 Infiniti QX56 I noticed I have to press down harder on my brakes to come to a stop. At one point the brakes go all the way to the floor and the brake light illuminates. I know I don't need brake pads because they were replaced 2 months ago. I have also had my brake booster assembly replaced so I know it is not that. I don't know what to do because I keep having issues with this vehicle. Service brakes
While driving ,I pressed on the brakes and the pedal dropped down and started making a weird noise kind of like loose metal parts and the truck wouldn't stop. The abs light turned on. It felt like the brakes locked up . I managed to pull to the side of the road and shut the truck off. I turned it back on and it seemed to reset the system. Brake petal raised back up and the check engine light shut off. Service brakes · reported at 92,000 miles
