“The clutch pedal (already a known problem by Mazda, but no recall has yet been announced) cracked while I was driving last year. I was on hwy 13 in minnesota and barely got control of my speed (was barely able to maintain use of the clutch) it sat until I could get it repaired, the same pedal is now craking in another spot, working on getting it repaired before it breaks again, this time will reinforce it.”

NHTSA complaint #10908280, filed 2016-09, 102,000 miles

“Was driving normal conditions down a 35 MPH road when I went to upshift gears and depressed the clutch pedal, I heard a loud pop and the pedal went to the floor. The clutch pedal bracket cracked and popped off due to poor quality and bad engineering, in my opinion. This could have caused the transmission to lock up and cause an accident through loss of control. I was not abusing the vehicle/ have not abused the vehicle.. This item should not break in the manner it did.”

NHTSA complaint #10538614, filed 2013-09, 91,000 miles

“1. Clutch pedal felt about a 1/2 low (as if hydraulic fluid had an air pocket and needed bleeding) about two blocks before failure. 2. I was stopped at a light behind 3 cars in the right hand lane, shifted into first when the light turned green; accelerated very slowly and tried shifting to second gear but the pedal made a snapping sound and went to the floor, the engine stalled and the transmission was stuck in first until I let the car roll back a little and got it in neutral. …”

NHTSA complaint #10289927, filed 2009-10, 63,000 miles

“Failure of the clutch petal as it attaches to the firewall under emergency deceleration. The metal attaching the petal to the fire wall sheared on the vertical attachments. Caused a near accident, dangerous conditions of a vehicle stranded in a travel lane, and subsequent towing on the vehicle.”

NHTSA complaint #10425269, filed 2011-09, 145,000 miles

“1. Clutch pedal assembly would make pop noise when being depressed and released. 2. Clutch pedal bracket to firewall snapped causing clutch pedal to not return. Could not change gears or stop with car on. 3.had to replace with factory pedal (the same pedal that caused the problem).”
