NHTSA Complaint #11681737 — 2019 MAZDA CX-9

I am reporting a serious safety issue involving a defective suspension part (lower control arm) manufactured by Dorman and purchased from an online auto parts retailer. On October 7, 2024, I ordered a Dorman lower control arm for my vehicle and had it professionally installed on November 7, 2024 at Johnston and Magwood Wheels & Tires. On November 8, 2024, at approximately 5:40 p.m., while I was driving and made a hard brake, I suddenly lost steering control and my front left wheel collapsed. Fortunately, I was the only one in the car and managed to avoid an accident. My vehicle had to be towed to a nearby shop (Kal Tire) and was later sent back to the original shop for further inspection. On November 12, technicians confirmed that the newly installed lower control arm had failed, which caused serious damage to the suspension. I paid $1,774.10 in repairs in order to make the car safe to drive again. This is extremely dangerous — if I had been driving on a highway or with passengers, it could have resulted in a major accident or injuries. When I contacted the retailer about the warranty, they only offered to refund the part itself and refused to take responsibility for the damages caused by this defective product. I believe this part should be investigated for safety defects. When I searched online, I noticed Dorman has had similar recalls on control arms, which makes me even more concerned. I am reporting this incident to NHTSA in hopes that you will look into this part to protect public safety.
