“VEHICLES BRAKES SUDDENLY STOPPED WORKING CAUSING A LOW SPEED COLLISION. I HAD THE BRAKES INSPECTED, AND WAS TOLD THIS WAS A KNOWN ISSUE WITH MY CAR, BUT MAZDA DID NOT INITIATE A RECALL. I THEN DISCOVERED THAT THE NHTSA HAD STRUCK A DEAL WITH MAZDA, AGREEING TO AN EXTENDED WARRANTY WITH NO CUSTOMER NOTIFICATION. THIS IS A CLEAR CASE OF A GOVERNMENT AGENCY THAT IS SUPPOSED TO PROTECT CONSUMERS, SHIRKING THEIR DUTY. NHTSA AND MAZDA YOU SHOULD BE ASHAMED OF YOURSELVES!”
