“I was rolling in bumper to bumper traffic and went to second gear doing maybe 15 MPH and heard a cluck. At first I thought it was reflectors on the road as that was what it seemed like. I made a turn , and as the thunk persisted, I immediatly stopped and popped the hood and observed the motor fell forward in the the radiatior. It was due to the driver's side transmission mount that came loose.”
NHTSA complaint #10187417, filed 2007-04, 8,063 miles“Have a 2007 Mazda speed 3 with 4224 miles 4 months of ownership. Reported a strange popping sound to the dealer on saturday and was told that it was not normal , and to drop off the car at the earliest convenience. While driving to a friend's house I turned left on a street and accelerated once into 2nd gear. I accellerated some more and heard a loud bang, and then several sequential pops and noises. I popped the hood to see that the driver's side of the motor had fallen down. …”
NHTSA complaint #10190646, filed 2007-05, 4,224 miles“There have been a few complaints of the driver's side motor mount bolt coming loose on Mazda speed3s. I had visually checked mine from the bottom several weeks ago, and it looked okay, but today I decided to physically check it. I put the front on ramps and removed the battery and box. I got underneath and removed the under tray, but couldn't locate the bottom of the bolt (or so I thought). Then I put the jack under the transaxle and jacked up a bit until the car started to lift. I didn't see the head of the bolt pop up, so I thought it was tight. …”
NHTSA complaint #10184612, filed 2007-03, 2,970 miles“Shifting from 1st to 2nd gear was rough sometimes. I checked the torque on bolt of driver's side engine mount and it was loose. It turned under 30 feet-lb. Bolt was supposed to be 70-80 feet-lb from the factory. After bolt was tightened to spec shifting became a lot smoother. I was convinced that if bolt was not tightened failure of driver' s-side engine mount bolt would have eventually resulted in a couple thousand more miles. Vehicle only had 3000 miles on it -engine would have dropped over left side driveshaft, causing loss of control of vehicle. Refer to investigation pe07015 .”
NHTSA complaint #10190851, filed 2007-05, 2,000 miles“2007 mazdaspeed 3 : transmission mount became loose and caused mis-shifts, loud clunking noises and stability degradation. Asked dealer to tighten bolt but was unable to get them too. On personal inspection bolt was loose and transmission was free to move around. After torquing bolt to spec all previous mentioned symptoms went away.”
