The rear subframe is corroded with rust to the point of about to break into pieces. I did not have control of the vehicle and could not drive above 40mph, sudden pull to one side while braking, loose steering. I could have had a wreck if the subframe would have broke before taking the vehicle in to be inspected by an independent service center. I live over an hour to the nearest Mazda dealership and the car is not drivable. No warning lamps came on and I first noticed the problems around January 11,2023. The part looks completely tissue thin all over and the rest of the components look new bolted to it. I do have pictures from the independent service center. I think the car needs to be seen by a regional service manager like a Mazda engineer. This is not just rust this is a defective part that was to thin to begin with.

Crossmember rust from recall campaign 2818I is able to effect structural attachment despite recall work. The recall installed an "improved: cross member. This was not an actually replacement cross member, rather additional plate steel between the rear and front of the existing attachment points of the defective OE cross member. Improved cross member contains no provisions to support rapidly corroding lower control arm attachment point in original cross member. Added member for recall also does not appear to additionally support lateral stresses from control arm. Evaluation of original cross-member seemed inadequate to detect structural integrity based on condition of the cross member today. "improved" cross member does not support mounting points of the control arm. Based on recall documents, some "improved" cross members have supports for Lower Control Arm (LCA) mounts. This issued occurred with sudden change in steering and braking characteristics. Vehicle suddenly started pulling right. Issue further exacerbated after follow on braking. Passenger wheel suddenly lost alignment and camber is indicating lower attachment geometry change. I was able to control vehicle, but with significant effort.

My front sub frame was completely rotted, unsafe to drive and was repaired with Mazda's recall. It now appears that the REAR sub frame is rusting at an excessive rate. I have been reading several complaints where the same incidents are happening with the rear sub frame snapping while people are driving. Car is not safe. This needs to be addressed by Mazda. They are aware of front sub frame, but failed to include the REAR sub frame. Not sure what to do at this point, it will costs thousands to repair, yet is NOT SAFE to drive. Please look into this matter as this is a very serious issue and will result in serious injury or death.

While making a right turn, I hit the brakes to avoid colliding with someone who pulled in front of me and the passenger's side front wheel locked into a position turned to the right. I had it towed to a repair shop, where I was informed that the control arm had separated from the frame due to rust. It seems there was a recall for this issue in 2018 for certain states, and while I do not currently reside in one of the affected states, I used to and my car did for most of its life.

When maneuvering to or from parking when the steering wheel is turned and puts any pressure on the steering components the right front of the car makes a very loud clunking and popping and makes both steering and moving difficult. It has gotten progressively worse over the last 2 months so I did some research and found out about the possible corrosion issue of the front right subframe and recall "inspection". I will call my local dealer and schedule an appointment as it seems this car is under an open recall and was never looked at. I just bought it as a used car in mid October and mostly drive my truck all winter so it took awhile for this to surface.

- Meadville, PA, USA

I have the open and dangerous recall ( # 2818I ) still pending at this time. It was hard enough just to get the dealership, in order to inspect the car for corrosion in the concerning areas. I don't feel that the car is safe to drive at this time and prefer that no one rides with me when driving it, just for the safety of others. I'm very concerned that this fix will not come soon enough and the problem keep messing up my cars alignment. Causing all sorts of problems driving it, especially at high speeds. That's when a wheel wobble starts to happen in the affected areas of the front passenger side of the car. Please help!

While applying the brakes at approximately 30mph, there was sharp jolt, and the steering wheel jerked all the way to the right. The low-traction indicator light came on and the car was not able to be safely steered. Upon visual inspection, the front right tire was turned outward, while the front left remained straight. A mechanic confirmed that the issue was caused by a fully corroded sub-frame which had cracked in half.

My son was driving the car approximately 40mph on a state route in a rural area and experienced a sudden loss of steering control and sharp pull to the right when he was trying to brake. This nearly caused him to hit a truck. When he regained control he noticed the steering wheel was not aligned while going straight and the car continued to pull to the right. When he managed to make it home we jacked it up and removed the right front tire. I noticed that the cross member on the right side was completely rusted through. This was the only noticibly large area of rust on the car. The car is now undriveable.
