What owners report
I am filing a complaint regarding a safety-related failure of the driver's seat bracket in my vehicle. The bracket has broken, causing the driver's seat to rock back and forth while the vehicle is in motion. I took the vehicle to an authorized dealer for inspection, and they confirmed that the seat bracket has failed. I was also informed that the replacement part is no longer in production and is unavailable. This condition poses a significant safety risk. A loose or unstable driver's seat can impair vehicle control, increase driver distraction, and reduce the effectiveness of seatbelt and airbag systems in the event of a crash. As a result, this defect substantially increases the likelihood of an accident and the risk of serious injury. I am aware that there have been numerous similar complaints regarding this issue, yet no recall has been issued. …
I was driving home recently and the back of my seat near the base gave out on me, the lower back/bottom raising motor was working but the seat was not going up. Upon inspection I found that the welds on the seat bracket had broken, going online and searching found me countless forums of seat brackets breaking during driving. Two main issues with this 1. I almost lost control due to the sudden drop 2. If I was to get into a collision the seat is not secure whatsoever. This is not an uncommon issue and I am astonished no recall has been given Sources of similarity [redacted]
Tl* the contact owns a 2006 Infiniti M35. The contact stated that the driver's seat was turned towards the right and the right back side of the seat was twisted. The dealer and manufacturer were not contacted. The vehicle was not diagnosed or repaired. The failure mileage was 83,000. * consumer stated two days after I filed my complaint with nhsta, the other side of the drivers seat frame broke. Luckily I had just sat down in the drivers seat. If I was driving when this occureed I could have been involved in an accident. When the seat frame suddenly broke this would have put me into a bad position if the airbag deployed that could have caused further injury. I purchased a new seat frame with motors for my car from the Infiniti dealer and had the seat repaired by the valley upholstery shop. See attached parts and repair receipts. Updated 11/01/18
