3 Front Suspension Control Arm problem

Failure Date: 03/30/2016

In 2016 I got a recall #8515g and that was performed by Mazda dealer on March 16 2016 (see doc attached) after the recall we have starting hearing a horrible noise, and mostly in winter, so I have took again to Mazda to inspect twice but they have hear that noise and have found anything. This past weekend they were more deeply on this inspection and what they found is the rf low control arm joint (ball joint) has play rf outer tie rod end has play too (see attached report from Mazda) the costs estimates to fix this problem is about $587 plus taxes. . What they say about the noise is probably comes from this issues which was supposed fixed by the recall but after 20000 miles this issues is coming again. . What they say this is not normal kind of this repairs could be longer than 10 years with not such a issues. . My concerns are the safety on my family, now my wife and my grandkids are driving this car everyday, and I'm putting them on a unsafety situation by this recall. . . .

4 Front Suspension Control Arm problem

Failure Date: 09/28/2015

I was dropping my children off to daycare turning into the parking lot and going over a bump when I heard a loud "pop" toward the front of the car - the car completely stopped dead - I got out to find the front right tire was cocked hard left and was off its control arm - some fluid was also leaking out of the axle area. This happened the Monday morning after I received the recall notice from Mazda this past weekend! I had the form in the car to call for service this week. I have called the service center but they have said they will not be able to look at the car until Thursday - now I will have towing and rental expenses connected with this defect. Fortunately no one in the car was hurt or that it didn't fail on the highway!.

6 Front Suspension Control Arm problem

Failure Date: 06/09/2015

We were coming home from our son's baseball game when this incident occurred. There were 2 adults and 3 children in the car at the time of incident. We were traveling in the middle lane of a 3 lane highway and were going about 65 mph, which is the speed limit on this highway. Out of nowhere, there was a very loud "pop" sound and you could feel the car shift a little bit. I was not able to control the vehicle at all. I put my foot on brake lightly to try and bring the car to a stop without slamming the brakes since we were on highway. The car briefly jerked to the left and then drifted to the right. It continued to drift to the right and I was able to bring to a complete stop about 2-3 feet from the edge of highway inside lane. The weather was clear and it was just starting to get dark. There were plenty of other vehicles traveling on highway at the time, but this happened at just the right time when there were no other vehicles to the left or right of us. If it would have happened 15 seconds earlier or later, it would have been impossible to avoid hitting another vehicle because I was unable to control where the car was going. It was definitely a very scary situation and we feel extremely lucky. Since the car was undriveable, I had to call aaa to come get vehicle and take to local auto shop. They told me the ball joint completely snapped/separated and I would need new tie rods, ball joint, control arm, axle, quick strut and tire on front driver side. This was the second time this happened within 5 month period. The same thing happened to front passenger side 5 months earlier at low speed in a parking lot. We had repaired and then it happened again to the other side in this situation, which was much more dangerous situation. In both cases, the ball joint completely separated.

7 Front Suspension Control Arm problem

Failure Date: 04/03/2015

Was driving my car with children in it when the wheel fell off and axel cracked. It caused front end damage I couldn't get out of the driver side door because it wouldn't open. Had to pay to get all of that fixed. I just receive recall 8515g. My issue with this is that the recall does not correct the issue. The reason for the recall is that water get leak into the suspension and cause corrosion. Replacing just the control arms and ball joints does not prevent this from happening again. Water can still leak into the suspension and the new parts could could corrode, become loose and cause the same thing to happen again but this time it could result in more dire consequences. We were lucky I was traveling at a low rate of speed the first time it happened. This is forcing us to buy a new car when we still owe $8000 on the Mazdaz we want to be reimbursed for this and the accident we had and the risk it out the lives of me and my children in. Furthermore Mazda said there is a shortage of parts which means they won't replace if there is no sign of looseness. This is rediculous as my crash occurred a few months after being inspected. They are endangering lives.

8 Front Suspension Control Arm problem

Failure Date: 01/08/2015

The contact owns a 2007 Mazda cx-9. While making a slight right turn at approximately 5 mph, an abnormal sound came from the front passenger side of the vehicle. The vehicle was towed to an independent mechanic where it was diagnosed that the inner and outer tie rod, ball joints, control arm, and axle needed to be replaced. The vehicle was repaired, but the failure recurred. The manufacturer was not notified of the failure. The failure mileage was 89,099.

9 Front Suspension Control Arm problem

Failure Date: 08/07/2014

The passenger front wheel disconnected from the lower control arm, resulting in immediate loss of control of the vehicle. Fortunately the vehicle was being driven thru a residential area at a low speed. Two months prior to the failure, the car had a front-wheel alignment, and the mechanic assured me that there was no detection of the imminent failure. I certainly do not wish to have this occur at highway speeds. I had both lower front ball joint/lower arm assemblies replaced. I still have the failed part in case you are interested.
