2007 Infiniti M35 seats problems

Filed Mar 30, 2026 · Seats · CO

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. Given the safety implications and apparent frequency of this defect, I believe this matter warrants further investigation and corrective action.

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 [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The left front driver seat began moving slightly fwd/back when braking and accelerating at @ 75k miles. Then that assembly just broke (seat settled) as I got in the car one day and I can no longer move it back and forth or up/down at all. So rail broke and then the seat motor died. I have read of so many of these stories with this year vehicle. Upon research, I found they only used this assy from 5/2006 to 9/2007. I have to believe nissan/infiniti knew they had an issue with this design.

As I was driving on a normal city street in regular traffic, the driver seat suddenly started moving forward, powered by the seat control. I reached down to push the lever/seat control back, but the seat motor would not stop; it pushed the seat fully forward. I stopped the car to move it back and was unable to. The other seat functions worked: up, down, tilt, etc. This has happened on four separate occasions. The last three times the seat motor has started working again of its own accord. This time it is still stuck forward.

During normal operation, the seat has failed in it's original design intent. I believe that the a failure in some component under the seat caused stress on the pivot point for up-down movement in the seat and over an extended period of time the point finally sheared. I believe the extensive stress was caused because of the automatic seat movement that occurs when the driver enters and exits the vehicle the bracket which allows the seat to move up and down with the powered control has failed on both sides of the left front bucket seat. The seat now moves freely forward and back and poses a serious safety risk to myself and anyone else who might be driving the vehicle. This puts me in a terrible position because as a concerned consumer I have to worry about the fact that an accident could be fatal due to component failures. Should I move forward with getting rid of the vehicle, either by selling it to another person or trading in the vehicle, I put someone else in risk and/or will take a huge loss on the value of the vehicle because of the condition which was caused by poor design and/or quality testing. This is a serious issue and needs to be remedied by nissan USA immediately!

The driver seat rear bracket broke under normal use and has resulted in the seat not being securely attached to the frame. I was entering the parked vehicle when it broke. As a result the seat flips forward when stopping which is extremely unsafe. Judging by the hundreds (m/b thousands of complaints online) this is clearly a major manufacturing defect that nissan should repair at no cost to owners.

Tl* the contact owns a 2007 infiniti m35. The contact stated that driver side seat belt failed and the seat looked as if it were positioned incorrectly and unbalanced. When the contact attempted to adjust the seat, it failed to move without warning. The vehicle was taken to the local dealer (infiniti suitland, 4800 branch ave, suitland, md, 20746) where it was diagnosed that the frame /lever failed and that the entire seat needed to be replaced. The vehicle was not repaired. The manufacturer informed the contact that there was no recall and that the replacement would be an out of pocket expense. The failure mileage was approximately 130,000.

The two brackets that support the seat back on the drivers seat have snapped / sheared. The seat back is no longer supported and the seat base raising mechanism no longer works. The problem started on the right side and after a couple of weeks the left side failed.
