2011 Infiniti G37: what breaks, and at what mileage
What breaks on the 2011 Infiniti G37
On the 2011 Infiniti G37, the failure owners report most often is airbag warning light or occupant sensor fault, and the reports cluster around 65,000 miles. The earliest to appear is other speed control problem, reported by a median of 10,000 miles. Overall it scores 71 out of 100, high risk for a 2011.
High risk for a 2011 — 146th riskiest of the 283 2011 vehicles we can rate. 130 owner reports; fleet size estimated from this year's own recall paperwork.
What owners report breaking
Owners have reported 24 named failure modes on the 2011 Infiniti G37, and the three most-reported carry 35% of everything filed.
Airbag warning light or occupant sensor fault leads with 27 reports, about 45 per 1,000 vehicles and with the middle half of reports between 58k to 75,000 miles.
Other body or interior problem follows with 10 reports, median 70,000 miles.
Sunroof failure or glass breakage follows with 9 reports, median 75,000 miles.
By system, the reports fall mostly into airbag (33), body (20) and adas (9).
When these failures get reported
81 of the reports on the 2011 Infiniti G37 came with an odometer reading, and half of those were filed before 57,500 miles.
Cumulatively, 42% by 50,000 miles, 94% by 100,000 miles and 99% by 150,000 miles of the dated reports had been filed.
The busiest stretch is between 60,000 and 70,000 miles, which alone holds 19% of the dated reports.
31% of the dated reports were filed below 36,000 miles.

What happens when these parts fail
Across the named modes, 8 mention a crash, 1 a fire and 3 an injury. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.
The average severity weight across every report on this year is 3.96, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.
What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: airbag warning light or occupant sensor fault at $300–$1,600, other body or interior problem at $200–$2,000, sunroof failure or glass breakage at $700–$4,500 and other speed control problem at $250–$2,000. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
8% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.

How often, against how many were built
Scaled by an estimate of how many of these cars exist, the 2011 Infiniti G37 draws about 218 per 1,000 vehicles, which puts it in the 99th percentile of complaint rates among 2011 vehicles we can rate.
That denominator is the weakest number on the page and it is fair to say so plainly. Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound.
The working figure is 596 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2011 vehicles, which is what the risk score uses, is far more robust than the rate itself.

Airbag warning light or occupant sensor fault
Passenger airbag light came on (april 5, 2017)while on highway. Had dealer diagnose and the results came out as the sensor has failed.the whole seat needed to be replaced. Costing over 6k usd, sensor cant be replaced by itself is absurd. Extended warranty did not cover it either even with premier care from all state.I tried getting it taken care of because lives are at stake but what can you do if you cant afford to fix it. It costs a seat or a down payment towards a new car. They should issue a recall for this. Ive seen online that im not the only one whose having this issue especially from nissan/infiniti
The airbag light flashes red on the dash panel indicating the passenger airbag is not on. It also shows on the panel under the air conditioner controls that the passenger air bag is off. This is a safety issue and it is due to a faulty safety restraint system sensor the in the passenger bottom seat. Infiniti has had recalls and issues with this SRS system in the passenger seat while they did not recall the 2011 infiniti g37. My g37 has approximately 23,500 miles and they want over $5,000.00 to replace the whole seat bottom. This is a defective product and someone needs to be held accountable. To top things off, my dash is melting and I know they had a class action lawsuit in florida with nissan melting dashboards in 2008. I guess this could also be a safety issue since the dash is sticky and hot and if a child were to touch it they could possibly get burned not to mention the mess. Infiniti consumer affairs said they would not remedy either issue. What a quality product......I will never buy another nissan/infiniti vehicle and have owned 5.
Other body or interior problem
This is a hardtop convertible car whose roof folds into the trunk space when the top is down. Unlike a previous hardtop convertible I owned (volkswagen eos), the roof on the infiniti goes down even when there is an obstruction in the trunk space (such as a book). [the roof of the eos would not go down until the obstruction was removed]. This has happened twice with the infiniti, causing thousands of dollars of damage to my car. My concern is that if a child were to climb into the trunk (god forbid) and the top were to be engaged, there would be nothing to stop the roof from crushing the child. This seems like a serious safety shortcoming. I called infiniti motors and expressed my concern; they created a file and basically said there was nothing they could do. *tr
Tl* the contact owns a 2011 infiniti g37 convertible. While attempted to close the hard top, the top became stuck. The vehicle was taken to napleton infiniti of tallahassee (located at 3355 capital cir ne, tallahassee, fl 32308, (850) 297-1488) where it was diagnosed that the shelf fractured and the hard top needed to be replaced. The vehicle was not repaired. The contact stated that the hard top was previously repaired three times by the previous owner. The manufacturer was notified of the failure and stated that the vehicle was sold as is. The contact was provided case number: 28153425. The failure mileage was 85,873.
Recalls on the 2011 model year
NHTSA has issued 1 recall campaign covering the 2011 Infiniti G37, affecting an estimated 596 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.
The campaigns cover visibility:power window devices and controls. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.
Recalls also distort complaint counts. Publicity about a campaign reminds owners that complaining is possible, so reports for a recalled component often spike after the recall rather than before it.
VISIBILITY:POWER WINDOW DEVICES AND CONTROLS
1,788 vehicles 2011-11-04- Defect
- Nissan is recalling certain model year 2011 and 2012 infiniti g37 coupe vehicles and certain model year 2011 nissan 370z vehicles manufactured from july 2, 2011, through august 29, 2011. Due to a programming error, the power window switch controller in the subject vehicles was manufactured out of specification.
- Consequence
- The threshold for auto reverse activation is higher than the nissan specification. Should a body part become trapped by a closing window, a pinch injury may result.
- Remedy
- Nissan will notify owners, and dealers will replace the power window switches with new ones free of charge. The safety recall began on december 5, 2011. Owners may contact nissan at 1800-647-7261 or infiniti at 1-800-662-6200.
Recall work is free at a franchised dealer regardless of the car's age. Check the VIN at nhtsa.gov/recalls before assuming it was done.
How it ranks in the 2011 field
The score at the top of the page, placed among its peers. The zones are the same thresholds the scorer applies, read out of the scorer itself, so the picture and the band word cannot disagree.
Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.
- Left fewer and less serious reports
- Right more, or worse

How 2011 compares with the other years
High risk for a 2011 — 146th riskiest of the 283 2011 vehicles we can rate. Every score on this site is a rank inside its own model year, which is what makes a 2004 and a 2019 comparable at all.
Across the 6 model years of this car that carry enough reports to score, 2008 comes out best at 64 and 2012 worst at 76, with 2011 itself at 71.
If the model year is negotiable, 2008 scores lower than 2011 by a margin worth acting on. Same body, same engines, different luck — usually a supplier change or a mid-cycle fix, which the complaint data can show but never explain.
Within the 2007–2013 generation specifically, 2008 is the strongest year at 64 and 2012 the weakest at 76.
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.
Within the 2007-2013 generation, 2008 Infiniti G37 scores best at 64 and 2012 Infiniti G37 worst at 76.
What to look at before buying one
The mileages below are where the first quarter of reports for each mode had already been filed, which makes them the point at which a fault is worth looking for rather than the point at which it happens: other speed control problem from about 2k and airbag warning light or occupant sensor fault from about 58k.
On a 2011 Infiniti G37 with more miles than that on it, the useful question to put to a seller or a mechanic is whether other speed control problem has been dealt with, and if so with what parts and at whose expense. A car that has already had the repair is in a different position from one that has not.
None of this is a diagnosis. It is a list of what other owners of the same model year reported, ordered by when they reported it, which is a good place to point an inspection and a poor place to stop.
The limits of complaint data
130 owner reports; fleet size estimated from this year's own recall paperwork. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.
Of those 130 reports, 81 carried an odometer reading, so the mileages here describe 62% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".
Named failure modes come from matching phrases in the complaint text, so a badly worded complaint can land in the wrong bucket. The effect washes out across hundreds of reports and does not wash out across five.
And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.
