What owners report
Owners of this model year most often report the passenger air bag warning light coming on or flashing, usually traced to the front passenger seat occupant sensor, along with stalling or shutting off at low speed and refueling that stops well before the tank is full. A sticky, melting dashboard and door lock actuators also come up repeatedly in the complaints.
- Air bags
Passenger air bag light on / occupant sensor fault
- 27 complaints (28%)
- median 79,193 mi at 7.3 yrs old (22 state mileage)
- 3 mention a crash, fire or injury
- owner-quoted repair $5,450 (median of 6 quotes)
- filed 2008–2026
Owners describe the air bag warning light illuminating or flashing and the passenger air bag indicator showing off even when an adult is seated. Several say a dealer or independent mechanic diagnosed a failed occupant classification sensor or seat cushion unit, and some were quoted replacing the seat bottom at high cost. Some note the vehicle was not covered by the occupant sensor recall despite similar symptoms, and some dealers reported they could not duplicate the light. Reported from very low mileage up past 130,000 miles, with many between about 40,000 and 120,000 miles.
Recall 08V5210002 related service bulletins
What to check: With the engine running, have an adult sit in the front passenger seat and confirm the air bag on indicator stays lit, then watch for a flashing air bag lamp. Ask whether the occupant sensor or the recall work was ever performed for that VIN.
2 excerpts from owner complaints in NHTSA records
“Infinity has a voluntary recall, nstsa #08v-521 for the passenger air bag occupant sensor (ocs) on 2008 infinity G35 with error code b1022. My car has error code b1018 with is the same issue and they will not replace the sensor. They want to charge me $7000 to replace the seat bottom. This should be covered under the recall.”
NHTSA complaint #11093953, filed 2018-05, 108,000 miles“Air bag light has been on for six months; local dealership said it would cost between $5,000 bs $6,000 to fix passenger seat airbag inflator -- because it required the replacement of the entire seat frame. Car has 21,000 miles on it. I bought it new. No accident; I find no record of a recall.”
NHTSA complaint #10992462, filed 2017-05, 20,000 miles - Engine
Engine stalls or shuts off at low speed
- 14 complaints (15%)
- median 103,000 mi at 6.6 yrs old (11 state mileage)
- 1 mention a crash, fire or injury
- filed 2009–2023
Complaints describe the engine quitting without warning at low speeds, often while slowing for traffic, turning, or leaving a parking lot, with the car restarting after shifting to park or neutral. Several mention battery, check engine, or slip lights appearing just before the shutdown. Owners report dealers and independent shops were often unable to find or duplicate a cause. Mostly reported between about 70,000 and 130,000 miles, typically in low-speed traffic or at intersections.
What to check: Test drive at low speed and at idle in traffic, watching for a stumble or drop in rpm. Ask whether any diagnostic codes were stored or any throttle or idle work was done.

“The car idles when taking off even after warming it up... While cars are passing me by. It acts like it wants to cut off while in traffic. It was raining on the passenger side. I can't even filled the car up with a full tank of gas. Only had the car for 3 weeks and the service engine soon light come on. Took it back multiple times and still not fixed”
NHTSA complaint #11292365, filed 2019-12, 155,000 miles“When driving slow, 5 to 15 MPH merging onto busy interstate 84 highway without warning the battery light, and brake light will come on and engine shuts off. The car lights, radio still work. Put the car in park start the engine and its starts up as normal. This car has gone to the dealer, and 2 other shops 800.00 later its still having a stalling issue. I have a 4 year old and this issue scares me.”
NHTSA complaint #10689808, filed 2015-02, 103,000 miles - Other or unknown
Sticky, melting or cracking dashboard
- 11 complaints (12%)
- median 67,400 mi at 8.4 yrs old (5 state mileage, few)
- filed 2014–2024
Owners describe the dashboard surface becoming tacky and shiny and then cracking, with the glare reflecting onto the windshield and making it harder to see. Some report sunroof drain tubes breaking apart and water reaching the interior. Owners who raised it with a dealer say they were told nothing could be done about the dash material. Reported from about 67,000 to 100,000 miles, typically on cars several years old in warm climates.
What to check: Feel the top of the dash for tackiness or shine and look for cracks, especially near the passenger air bag seam. Check the headliner and carpet for water stains that could point to drain tube leaks.

“The dashboard on my vehicle is starting to crack everywhere and near the air bags I looked up the problem and it seems a lot of Infiniti owners are getting the same thing on their dash together with some stick liquid”
NHTSA complaint #10779074, filed 2015-10, 100,000 miles“Two complaints. 1. The dashboard in my 2008 G35 is melting. It has a tacky feel and is easily damaged when touched. Many cracks in the dashboard. At times the shiny appearance of the dashboard reflects light on the windshield and makes it difficult to drive. 2. The sunroof has drain channels for draining off water that accumulates around the sunroof. The drain channels are plastic pipes that run through the a-pillar and spill onto the roadway underneath the vehicle. …”
NHTSA complaint #10863961, filed 2016-05, 67,400 miles
Buying note. Check the passenger air bag indicator with an adult seated in front and ask about any occupant sensor repair history, since that is the most frequent complaint and can be expensive. A low-speed test drive and a full tank of fuel will also reveal the stalling and refueling symptoms owners describe.
Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records.

Example complaints
Air bags: “Air bag warning light for the passenger seat remains on. I took it to the dealer but was told that I had to pay (nearly $4000) to test the problem and then to replace the seat. Dealer never told me that the car with this problem was subject to a recall, which started in november 2008.”
NHTSA complaint #10629955, filed 2014-09, 100,000 milesOther or unknown: “In my car, my radiator failed. That then made the transmission fluid and the coolant mix. My fluid in my radiator and transmission are like slime in there. My car doesn't function like it should.”
NHTSA complaint #11255739, filed 2019-09, 95,000 milesElectrical system: “My car has been stalling while driving at low speed. Several warning lights come up (check engine light, slip light, battery light) and then the engine shuts down completely. Upon placing the car in park, I am able to re-start it. This is a major safety issue. I believe my car is part of recall number 03v455000 - engine and engine cooling. However, my VIN is not part of the recall, but I am experiencing the same issues associated with this recall. This needs to be re-addressed. …”
NHTSA complaint #11317713, filed 2020-03, 167,000 milesEngine: “Almost daily stalling at low speeds. When coming to a slowdown, the vehicle will stall with no error codes or lights given except for power completely turning off. This has resulted in numerous near misses since steering is then not powered and at times in the middle of an intersection. Restart is possible by putting the car in neutral and restarting. I worry that this can cause a wreck when stalling in the middle of the intersection with traffic coming. At times, when coming to a slowdown, the car will stutter as if rpms drop very low but does not stall. …”
