CarComplaints.com Notes: Radiators are still cracking, leaking coolant and destroying transmissions. Which is a shame when you consider that otherwise, this would be a great small pickup truck.

On my way to work, 4/13/2014, Sunday a.M. sudden loss of power (no forward motion) I had to immediately pull over to the slow lane and stopped. There was no other option on alameda blvd. All lanes on both sides of the blvd. Had to tow to carson Nissan, they inspected the transmission and said it was bad due to the radiator...... I have noticed other complaints and I am wondering if this site is worthwhile I truly hope so, please and thank you.....
