A D V E R T I S E M E N T S

After exiting a freeway and decelerating and braking normally, I waited behind other traffic for the light to change, with my foot on the brake and the gear selector in drive. Suddenly, the engine rpms increased sharply and my car moved forward. I was unable to hold the car in place with the brake pedal. I depressed the brake so hard that I sensed the pulsing of the ABS system. This was completely unexpected, so by the time I shifted into neutral, my car had struck the rear of the one ahead. I then turned off the ignition. No damage was done, and the other driver and I agreed it was a "non-reportable" accident. After the incident, I waited about 30 seconds and restarted the car. I continued to drive home without incident. My car had operated normally under various traffic conditions for the previous two hours. I was not using the air conditioning at the time; I was running the ventilator fan system. It is highly unlikely that I had depressed both brake and accelerator together, as I had just braked normally and did not move my foot from the brake pedal. (I checked later to see if it was even possible to touch both pedals simultaneously. I could not, without putting my foot at an awkward, angled position.) I also checked for a jammed floor mat, but it was well clear of the pedals. This unexpected acceleration occurred at ca. 66,000 mi. There was one such previous incident, at ca. 14,000 mi. The Mazda dealer that regularly services the vehicle inspected the car and ran various electronic, throttle, and vacuum tests, with advice from Mazda's national service center. No defects were found. A senior service manager also drove the car for some seven miles under various traffic conditions, but the problem did not recur. A service advisor at the dealership suggested it might be an intermittent electronics problem; and also that my wife and I shift from drive to neutral each time we stop in traffic, and watch then for sudden RPM increases.

Brakes suddenly failed while driving barely avoiding a serious collision. Brakes were working fine before complete failure. Upon inspection by a mechanic at midas the left front brake line was rubbing against the axle boot resulting in a break in the line and tearing of the boot. This resulted in a complete loss of brake fluid. Previously the right front brake line had fallen off during pad inspection.

The contact owns a 2004 Mazda 6. the metal brake lines were rubbing against the cv boots. They have worn through both sides of the boots and resulted in holes forming in the brake lines itself per the mechanic. He also stated that this was a manufacturer's defect. The manufacturer has not been notified. The vehicle is currently in the repair shop. The failure and current mileage was 70,000. The VIN number and engine size are unavailable.

Car makes a noise from brakes when turining all the way to the left and applying pressure to the brakes. It's not a normal brake squeal, it's more of a moaning noise. It is definately coming from the driver's side front brake. It does not happen when it turns to the right. It also normally occurrs when the vehicle/brakes are hot. It has been occurring for the past 10 months. Two seperate Mazda dealerships say there is no problem and they "can't reproduce the sound." At pinnacle Mazda (renton, wa), the service manager said there was no problem. I had a mechanic ride with me to try and make the sound. During the ride, he stated that Mazda has been having a "ton of complaints about brakes, especially the rx-8, but also on the Mazda 6 and Mazda 3." he further stated, "it doesn't seem like Mazda can find a fix either." I thought this was interesting coming from a Mazda mechanic. Ultimately, my car still makes the noise. I have a co-worker who has the same car, and it too makes the same noise.
