“Brakes turned to sponge on at least three separate occasions in fall 2009, again in feb 2010,summer 2010 and again 12/ 22/ 2010. At first occurrence winter of 2009 I assumed I had hit ice and was unable to brake for that reason. However, every incident after that confirmed that road condition was not a contributing factor. During first event the brakes were not functioning,car continued to move forward at red traffic light. Brake failure recurred twice at 4 way stop and again on residential street as I am preparing to park. …”

NHTSA complaint #10372244, filed 2010-12, 57,000 miles

“Hydraulic master cylinder in the clutch malfunctioned causing the clutch to stay engaged. I did not have a collision but was forced to leave the roadway to avoid having a truck strike me from the rear. When I took the vehicle to a dealer they refused to look at the vehicle unless I prepaid them, and they would later determine if I would reimbursed. Note that the car had only four years and 27k miles of a 10 year/100k warranty. This defect is extremely dangerous and someone not having multiple defensive driving courses and training may not have known how to respond. …”
