2007 Infiniti M35 Problems

What owners report

Owners of this model year most often describe the driver's seat track and weld breaking, a steering wander on grooved or uneven pavement that many call tramlining, and the passenger airbag inflator recall. Seat and airbag complaints tend to appear at higher mileage, while the steering complaints are often filed at lower mileage.

1. 1
   Seats

   Driver's seat track or weld breaks, seat leans or drops

   • 37 complaints (24%)
   • median 99,000 mi at 7.8 yrs old (34 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $1,200 (median of 9 quotes)
   • filed 2011–2026

   Owners describe the driver's seat sliding slightly forward and back under braking and acceleration, then progressively leaning toward the center console or dropping on one side. Several say a dealer diagnosed a broken seat track or adjuster weld and quoted a full seat base or adjuster assembly replacement. Some report the seat no longer moves with the power controls, or that it is loose enough to shift by hand. Mostly reported between about 50,000 and 130,000 miles, often after a period of small sliding movements.

   What to check: Sit in the driver's seat and push it side to side and fore-aft; check for a gap between the seat and center console and ask whether the seat base or adjuster has ever been replaced.

   2 excerpts from owner complaints in NHTSA records

   “While braking I feel the seat slides forward. Then when accelerated the seat slides back. I contacted the dealer, they are aware of the issue, but will not repair it because it is out of warranty. This is a safety issue, as it could cause the driver to engage the brake or gas peddle greater than anticipated due to the movement of the seat.”

   NHTSA complaint #10597830, filed 2014-06, 98,000 miles

   “While driving to work and proceeding to a stop light my seat just feel on one side and took a dip. When this happened it definitely startled me. I didn't know what to do and could barely drive. I was able to safely get to my destination, which happened to be 2 minutes away at that point and look at the seat and it turned out to be nothing I can do. Now the seat lifts and drops on its own.”

   Steering

   Steering wanders or jerks on grooved or uneven roads

   • 19 complaints (12%)
   • median 48,909 mi at 4.2 yrs old (18 state mileage)
   • filed 2008–2015

   Complaints describe the car pulling or jerking left and right when crossing grooves, ruts, or small road imperfections, sometimes abruptly enough to leave the lane. Many owners call it tramlining and report that new tires, balancing, and alignments did not resolve it. Some say a dealer attributed it to the tires or found no fault, while others were told the steering rack was involved. Reported from very low mileage up to about 100,000 miles, typically at highway speeds on grooved or rough pavement.

   What to check: Drive the car at highway speed on a grooved or patched section of road and see whether the wheel pulls; ask whether tires, alignment, or steering rack work has been done.

   “2007 Infiniti m35x, has a tramlining issue with the steering rack system. Today while driving it forced me out of my lane and I nearly struck the adjacent vehicle. This is a severe safety issue and I'm concerned for the safety of my children. This needs to be corrected before someone is killed.”

   NHTSA complaint #10553286, filed 2013-11, 105,000 miles

   “I have a 2007 Infiniti m35x which has a terrible problem with the steering when I am driving over a rutted or bumpy road. The steering will pull hard to one side or the other and one time almost took me off the road. The dealer says it's the tires, which are goodyear rsa original equipment on the car. However, I have driven their other cars with the same tires without any problems at all. I've owned many cars, including infinitis, without this problem and fear this is a very dangerous car as is.”

   Body and structure

   Cracked or sticky dashboard

   • 16 complaints (10%)
   • median 71,000 mi at 9.3 yrs old (7 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2014–2021

   Owners report hairline cracks spreading across the dashboard, often after the surface began to feel sticky or tacky. Several note the car was garaged and cleaned only with water, and that a dealer or the manufacturer declined to replace the dashboard because of the vehicle's age or warranty status. Typically reported between about 47,000 and 100,000 miles, several years into ownership.

   What to check: Inspect the top of the dashboard in daylight for hairline cracks and feel for a tacky surface, especially near the defroster vents.

   “In late 2012, I noticed hairline cracks beginning to form in various areas of my vehicle's leather dashboard. In approximately may-june of 2013, I notified Infiniti corporate customer service of this event. I was advised to bring the vehicle to my Infiniti dealer so they could create an incident report and gather photos. Then a review committee would decide whether Infiniti would replace the dash or provide some compensation toward replacement. …”

I had complained about several cracks on my dashboard in my 2007 Infiniti M35. My vehicle of low mileage and well maintained and kept in the garage.

   Takata passenger airbag inflator recall

   Mentioned in 4 of 60 sampled complaints

   Owners describe learning about the passenger airbag inflator recall on their own or waiting on parts, with some saying the vehicle sat at a dealer for an extended period awaiting the repair. A few complaints describe airbag deployment in a collision with injuries, and others note they were never notified. The recalls on this model year cover the front passenger inflator module. Reported across a wide mileage range, mostly above 100,000 miles, in vehicles that had not yet had the recall completed.

   “Takata recall I was never notified by Infiniti that there was a recall for a passenger airbag on my vehicle. I found out on my own that a recall existed. I purchased and financed my used Infiniti M35 through the dealer and financed through Infiniti finance. Now I have been told that the parts on back order until 2017.”

   NHTSA complaint #10920243, filed 2016-10, 146,000 miles

   “Takata recall my vehicle has been in the service dept since 10/31/2016 I was issued a rental car but I would like nothing more than to get the vehicle back that I am currently paying for. This is an inconvenience for myself and my family. Driving a rental is like walking on pins and needles. Being extra careful.”

   • median 78,000 mi at 6.9 yrs old (5 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2013–2022

   Complaints describe the engine stalling or dropping into a reduced-power mode while driving, sometimes with the service engine and VDC lights on, and one owner reports a pedal that failed to respond before a collision. Some reference the accelerator pedal sensor recall and describe replacing the pedal themselves before the recall notice arrived. Reported between roughly 70,000 and 105,000 miles while driving at moderate speeds.

   Recall 13V430000

   What to check: Ask whether the accelerator pedal sensor recall was performed, and note any stored codes or intermittent reduced-power warnings during a test drive.

   2 excerpts from owner complaints in NHTSA records

   “My pedal stopped working, then it cut completely off while I was driving on a major hwy doing 60mph. I just received a recall notice in the email yesterday 11.12.2013, NHTSA recall 13v-430, now, I spoke with a rep stating I will receive another notice. This action has already happened to me and I have replaced it out of my own pocket. I do not see why I should have to wait on a second notice. …”

   NHTSA complaint #10552039, filed 2013-11, 66,000 miles

   “The contact owns a 2007 Infiniti M35. The contact stated that while driving approximately 25 MPH, the vehicle stalled without warning. The vehicle was able to be restarted. The contact had not taken the vehicle to the dealer for inspection or the failure or repairs. The contact referenced NHTSA campaign id number: 13v430000 (vehicle speed control) but did not confirm if the vehicle was included in the recall. The manufacturer was not made aware of the failure. The approximate failure mileage was 100,004.”

   NHTSA complaint #10553706, filed 2013-11, 100,004 miles

Buying note. Check the driver's seat base and steering behavior on rough pavement during a test drive, and confirm by VIN that the airbag inflator and accelerator pedal recalls were completed. A pre-purchase inspection that includes the seat tracks and steering components is worthwhile on this model year.
