How we rated the best and worst Infiniti G35 years

We pulled together information from multiple angles to give you the full picture. NHTSA complaint logs showed us which years generated the most owner frustration, while official recall bulletins revealed systemic flaws Infiniti had to fix (cam/crank sensors, airbag wiring, brake light switches). Long-term owner reviews on CarComplaints and Edmunds added real-world context—what breaks at 80k miles versus 150k, what repairs cost, and which issues owners learned to live with versus the ones that forced them to sell.

We also combed through G35Driver and MyG37 forums, where enthusiasts document everything from timing chain tensioner replacement costs to which aftermarket bushings actually last. YouTube mechanic channels provided visual walkthroughs of common failures (Rev-Up engine teardowns, for instance). J.D. Power reliability scores and RepairPal cost data rounded out the research, giving us benchmarks to compare the G35 against rivals like the Acura TL and Lexus IS.

One pattern emerged clearly: oil consumption in manual “Rev-Up” engines and first-year build quality problems (especially on the 2003 model) dominate the complaint landscape. We cross-referenced transmission failure rates between coupe and sedan, automatic and manual, to see if certain configurations were safer bets. The answer? Yes—automatic G35s from the middle and late years tend to dodge the worst issues.

Most Common Infiniti G35 Problems

1. Engine Troubles You Should Know About

The VQ35DE engine is a workhorse that can easily crack 200,000 miles if you stay on top of oil changes and cooling system maintenance. But three recurring issues pop up often enough that you’ll want to inspect any used G35 carefully.

Cam and crank position sensor failures hit 2003–2006 models hard enough that Nissan issued a recall. When these sensors go bad, the car might stall at idle or refuse to start altogether. If you’re looking at an older G35, confirm the recall repair was done—it’s a straightforward sensor swap, but skipping it leaves you stranded.

Timing chain rattle shows up on 2003–2007 G35s, though not every car develops it. You’ll hear a tapping or rattling noise from the front of the engine, usually on cold starts. The culprit is premature wear of the chain guides and tensioners. If the chain gets too loose, it can jump a tooth or snap a guide, leading to expensive internal engine damage. Replacing the chain, guides, and tensioners before catastrophic failure costs $1,200–$1,800 in parts and labor—annoying, but far cheaper than a new engine.

Oil consumption in Rev-Up engines is the big one. Infiniti boosted power in 2005–2006 manual-transmission G35s (and the 2007 coupe) by revising the VQ35 internals and raising the redline. Great for performance, terrible for oil control. Many Rev-Up owners report burning a quart every 1,000–3,000 miles. The root problem lies in piston ring design; short of an engine rebuild or ring replacement, there’s no true fix. Some owners install oil catch cans or upgrade valve covers to reduce (but not eliminate) consumption. If you’re considering a 2005–06 manual or a 2007 coupe, bring a flashlight and check the oil level at your test drive—if it’s low and the seller seems surprised, walk away.

2. Transmission and Drivetrain Quirks

The 5-speed automatic and 6-speed manual transmissions are generally solid, but exceptions exist. Some 2007 sedans (the first year of the redesigned V36 chassis) experienced automatic transmission failures at surprisingly low mileage—one documented case involved a transmission dying around 35,000 miles. Harsh shifting or slipping gears usually point to valve body or solenoid problems; regular fluid changes help, but if an automatic G35 already has shifting issues, budget for a rebuild or replacement.

Manual transmissions face a different challenge: synchro wear, especially in third gear. High-mileage or hard-driven manual G35s often develop a grind when shifting into third. Double-clutching or switching to high-quality fluid (like Redline MT-90) can mask mild synchro wear, but once the grind is pronounced, you’re looking at a transmission rebuild. The AWD G35x adds another layer—monitor the transfer case fluid condition, because neglect there leads to costly repairs.

3. Electrical Gremlins That Frustrate Owners

Early G35s, particularly 2003 models, earned a reputation for electrical headaches. The Bose radio/head unit would fail, taking the climate control system with it (both functions share the same unit). Owners suddenly found themselves unable to adjust cabin temperature or fan speed because the entire center console stack had died. Replacement units aren’t cheap, and you’ll need one from a G35 or 350Z (they’re interchangeable) to restore full functionality.

Dashboard gauges can flicker or display incorrect fuel readings due to bad solder joints on the circuit board. The clock spring in the steering column wears out around 120,000 miles, disabling steering wheel controls for audio and cruise. Infiniti also recalled 2003, 2004, and 2006 G35s for a brake light switch that wouldn’t illuminate the brake lamps when you pressed the pedal—a serious safety issue that also triggers VDC/Slip warning lights.

Power window regulators fail often enough that it’s almost expected on older G35s. Windows get stuck halfway down or move sluggishly. Door lock actuators malfunction with similar frequency. Some 2007–08 owners traced door lock problems back to a defective sunroof assembly; water leaking from clogged sunroof drains apparently seeped into lock circuits. Clearing those drains and sealing the sunroof properly prevented repeat failures.

4. Brakes and Suspension Complaints

Premature brake wear topped the complaint list for 2003 G35s. Original pads and rotors wore or warped so quickly that some owners needed full replacements around 10,000 miles. Infiniti upgraded brake components in later years, and the optional Brembo 4-piston calipers (standard on 2003–04 coupes) offered stronger stopping power—though Brembo pads still dust heavily and wear fast under aggressive driving. Budget for more frequent brake service if your G35 has Brembos; parts are pricier than standard brakes.

Front lower control arm bushings leak or crack surprisingly early—sometimes by 40,000–60,000 miles. Worn bushings cause clunking noises and throw off alignment. Many owners upgrade to polyurethane bushings, which last longer and improve handling feel.

Alignment-related tire wear plagued 2003–04 coupes. Inner tires would develop “feathering” (uneven tread wear) that created a roaring road noise. Nissan issued updated alignment specs and revised suspension parts mid-2004 to fix the issue. If you’re looking at an early coupe, confirm the alignment has been checked and consider adding an aftermarket camber kit if inner tire wear persists.

Steering rack leaks were common on 2003 models. If you see power steering fluid pooling under the car, inspect the rack or high-pressure hose. Replacement isn’t catastrophic, but it’s an added expense on an already aging car.

5. Interior and A/C Annoyances

Dashboard cracks appear on 2007–08 second-gen sedans, usually around the front passenger air vent. Heat and UV exposure accelerate the problem; using a sunshade helps, but once the dash cracks, it’s cosmetic damage you’ll live with (replacement dashes are expensive).

Some owners report a musty odor from the A/C vents. Water can pool in the evaporator housing if the drain tube clogs, leading to mildew growth and a foul smell. Clearing the drain tube and treating the HVAC system with an anti-mold cleaner usually solves it, but the smell can return if you don’t keep up with maintenance.

The DVD-based navigation system in 2003–07 models is outdated now—slow to boot, maps years out of date. No widespread failures are reported; it’s just old tech. The Bose audio system sounds good, but CD changers and speaker amps can fail on high-mileage cars. Burned-out bulbs in the radio/climate display and loose trim pieces are minor fixes you’ll encounter on any 15-year-old car.

Which G35 Years Should You Skip?

2003: The Debut-Year Headache

The 2003 G35 logs the highest number of owner complaints and earns the title of worst year for the model. First-year cars often carry teething problems, and the G35 was no exception. Leaking steering racks, rapidly wearing brakes and rotors, and failing interior electronics (especially the Bose/HVAC unit) plagued early adopters. Many 2003s are still on the road and running fine, but you’re rolling the dice buying one. If a deal on a 2003 looks too good to be true, it probably is—factor in immediate repair costs and proceed with caution.

2005–2006: The Rev-Up Oil Burners

Avoid 2005–06 G35s with the manual transmission unless you have rock-solid documentation that the oil consumption issue has been addressed. Nissan’s Rev-Up VQ35 engine (found in 6MT models) delivers 298 hp and a 7,000 rpm redline, but many burn oil at alarming rates. Adding a quart every 1,500 miles gets old fast, and engine rebuilds aren’t cheap.

These years also fall under the airbag sensor recall—wiring under the passenger seat could wear and trigger airbag warning lights. Nissan fixed this for free, but confirm the recall service was completed. Unless you’re getting a screaming deal or the previous owner has meticulous service records proving the engine doesn’t burn oil, skip the 2005–06 manual G35s.

Automatic 2005–06 models don’t have the Rev-Up engine, so they dodge the oil consumption problem. If you like the first-gen body style and want a reliable G35, a 2005–06 automatic is actually a solid choice—just double-check that all recalls are done.

2007: First-Year New-Generation Wobbles

The 2007 G35 sedan introduced the V36 chassis with updated styling, more tech, and a nicer interior. J.D. Power gave it a 3 out of 5 reliability score—a noticeable drop from the 4.5/5 the 2008 received. Some 2007s experienced automatic transmission failures at low mileage, and various electronic bugs surfaced as Infiniti worked through first-year kinks.

The 2007 isn’t a disaster, and many owners never see a problem. But if you have the option between a 2007 and a 2008, the 2008 is the safer bet. Late-2007 builds (production dates toward the end of the model year) tend to be more reliable than early ones, so if you find a 2007 you like, check the door jamb sticker for the build date.

What About 2004?

The 2004 G35 doesn’t land on most “avoid” lists. Infiniti fixed several 2003 issues by then, and build quality improved. The 2004 still falls under the cam sensor and brake light switch recalls, so verify those were done. Some enthusiasts actually prefer 2004 because it offers factory Brembo brakes and the simpler first-gen design without the worst of the early bugs. It’s older now, but a well-maintained 2004 can be a reliable car—just inspect it carefully for typical age-related wear.

The Best G35 Years for Reliability

2005–2007 Automatics: The Sweet Spot

If you want a first-gen G35, a 2005–06 automatic sedan or coupe is your best bet. Infiniti had ironed out the 2003 quirks by then, electrical systems were more stable, and build quality improved. The 2005–06 automatics gained a bit more power (around 280 hp) without the Rev-Up’s oil consumption nightmare.

A 2007 sedan (second-gen) is also a strong choice if you want the updated interior and technology. It introduced new styling and more features while keeping the robust mechanical foundation. Just favor late-2007 builds or 2008 models if you want to minimize first-year-of-new-generation risk.

2008: The Most Refined G35

The 2008 G35 sedan is widely considered the best year overall. J.D. Power gave it a 4.5 out of 5 reliability rating, reflecting strong owner satisfaction and minimal issues. By 2008, Infiniti had been building the second-gen G35 for over a year, so early bugs were sorted. The 3.5L V6 had internal updates and showed no widespread oil consumption problems. Fit and finish peaked in this final year.

If you can find a clean, well-maintained 2008 G35, you’ll likely enjoy a very dependable car. The only catch: 2008 is sedan-only in the U.S. (the coupe became the G37 that year). But if you’re after a sporty luxury sedan that balances performance and reliability, the 2008 G35 is tough to beat.

Honorable Mentions

The 2004 G35 deserves recognition. Many enthusiasts favor it for the factory Brembo brake option and the simpler first-gen design with fewer electronics to fail. A clean 2004 with good service records can be very reliable—just account for typical early-year electrical quirks and ensure recalls are done.

If you’re open to stepping up a model generation, the 2009+ Infiniti G37 succeeded the G35 with a larger 3.7L engine (330 hp) and continued refinement. The 2010–2013 G37 models earned excellent reliability ratings. A 2010+ G37 gives you a similar driving experience with more power, newer tech, and potentially fewer miles—think of it as “the best G35 that’s not called a G35.”

Smart Alternatives If the G35 Isn’t Quite Right

Lexus IS 250/350 (2006–2013)

Lexus consistently tops reliability rankings, and the 2006–2013 IS is no exception. The IS350 matches the G35’s performance (306 hp V6) while offering Lexus build quality and lower long-term repair costs. The IS 250 is less powerful but efficient and upscale. These cars regularly exceed 100,000 miles with minimal issues. The rear seat is tighter than the G35’s, and AWD is available on the IS 250 if you need winter traction. If reliability matters more than raw power, the IS 250/350 is a top choice.

Acura TL (2004–2008)

The Acura TL delivers front-wheel-drive luxury with strong reliability. The 2004–08 TL (third generation) earned a 4.0 out of 5 reliability rating from RepairPal, ranking sixth out of 31 luxury cars. Owners routinely hit 150,000+ miles with few issues. The TL’s 3.2L or 3.5L V6 (270–286 hp in the Type-S) competes with the G35’s performance, and the interior is roomy and refined. While it’s FWD and handles differently than the RWD G35, it’s very dependable. The 2007–08 Type-S adds sportier suspension and Brembo brakes. If you want Japanese reliability and luxury without rear-wheel drive, the Acura TL is a smart pick—2006, 2007, and 2008 models are particularly solid.

BMW 3 Series (2006–2011 E90)

If driving dynamics matter most, the BMW 3 Series remains the class benchmark. The 2006–11 E90 generation (or earlier 2000–05 E46 models) delivers excellent handling, interior quality, and prestige. The 335i sedan (2007–11) offers twin-turbo power that outguns a G35.

Here’s the trade-off: BMWs cost more to maintain and tend to be less reliable as they age. The G35 is “cheaper to maintain than its German rivals.” Older 3 Series models often suffer cooling system failures, electronic issues, and high parts/labor costs. If you don’t mind the extra upkeep for a more engaging driving experience, a 3 Series can be very rewarding. Stick to well-maintained examples, and consider the naturally aspirated 328i/330i models for simpler reliability. BMW is a fun alternative, but not necessarily a better one unless driving feel is your top priority.

Infiniti G37 (2009–2013)

If you like the G35’s overall package but want something newer, the Infiniti G37 is the direct successor. It’s basically the G35’s evolution with a larger 3.7L engine (330 hp) and updated styling. The G37 maintained strong reliability—2010+ models are especially dependable. It keeps the G35’s strengths (sporty RWD/AWD option, strong engine, relatively low maintenance costs for a luxury car) while adding modern tech. A 2010–13 G37 could be considered “better” simply by virtue of being newer and slightly more refined while still offering solid used-car value.

Other Options

The Nissan 350Z/370Z shares the G35 coupe’s platform and engine but in a two-seat sports car form. It’s more raw and sporty but lacks rear seats and luxury touches. The Mercedes-Benz C-Class and Audi A4 from the mid-2000s offer smooth rides and prestige badges but tend to require more repairs as they age—stick to Japanese brands if reliability is paramount. For worry-free ownership without the sport sedan focus, a Toyota Camry or Honda Accord V6 from the late-2000s will be very reliable, though they’re family cars and don’t match the G35’s driving feel.

Final Thoughts: Picking the Right G35

The Infiniti G35 remains a compelling used car. It blends performance, luxury, and value in a way few rivals of its era matched. Focus on model years 2005–08 (automatics especially) and inspect common problem areas carefully: engine sensors, oil levels on Rev-Up models, timing chain condition, brake wear, and suspension bushings.

A well-maintained 2008 G35 often costs less to own over five years than buying a slightly cheaper 2005–06 Rev-Up car and dealing with engine repairs. Confirm all recalls are done (cam/crank sensors, airbag wiring, brake light switch), check maintenance records, and have a trusted mechanic inspect any used G35 before you buy.

If you’re considering alternatives, the Lexus IS and Acura TL offer better long-term reliability, while the BMW 3 Series delivers superior driving dynamics at the cost of higher maintenance. The G37 (2010–13) gives you the G35 experience with more power and newer tech.

Armed with this data, you’ll skip the hidden pitfalls and pick a G35 model year that delivers the power, luxury, and reliability you expect. Happy car hunting.
