Infiniti Ex35: Overview And Common Issues
The Infiniti EX35 entered the market in 2008, offering drivers strong V6 power, advanced tech, and a smooth ride. But luxury doesn’t always mean trouble-free ownership. Some model years, trims, and production runs suffer from repeated mechanical or electrical problems. These can range from minor annoyances to major engine failures.
Owners and experts have flagged several recurring issues:
- Transmission failure in some years
- Electrical glitches affecting navigation and sensors
- Timing chain problems leading to engine damage
- Interior wear that’s unusual for a luxury car
Let’s break down the 35 years and trims you should be cautious about, with specific reasons for each.

What Most Buyers Miss
- Early production months matter. The first half of each model year often has more problems. Look for a build date on the driver’s door sticker—later is often safer.
- Tech-heavy trims break more. Models with more gadgets (Premium, Deluxe, Tech) tend to have more electrical issues, which are harder to diagnose and fix.
- AWD adds complexity. All-wheel drive is great for snow, but more moving parts mean higher risk and cost if previous owners neglected maintenance.
Practical Tips For Avoiding Problem Ex35s
When hunting for a used EX35, go beyond the year and trim. Here’s what to check:
- Service Records: Ask for detailed records. A well-documented car, even from a riskier year, is usually a safer bet.
- VIN Check: Run the VIN through a service like Carfax or AutoCheck. Look for accident, flood, or salvage history.
- Recall Completion: Infiniti’s official website lets you check for open recalls by VIN. Make sure all critical repairs are done.
- Test Electronics Thoroughly: Spend time checking every button, sensor, and tech feature. Many issues don’t show up until you test them.
- Get a Pre-Purchase Inspection: An independent mechanic can spot hidden problems, especially with the transmission, timing chain, and AWD system.

The EX35’s early years are riskier than the Lexus or Acura, especially with transmission and tech issues.
Non-obvious Insights For Savvy Buyers
- Mileage matters less than maintenance. Some 2008 EX35s with 140,000 miles and perfect records are more reliable than 2012s with spotty service.
- Sunroof leaks are more than an annoyance. Water can drip onto critical airbag sensors in the headliner, disabling safety systems.
- Rust isn’t just a cosmetic issue. On AWD models, underbody rust can damage transfer cases and suspension—repairs can exceed the car’s value.

Should You Ever Buy A Risk Year?
It’s possible to find a good deal on a “problem” year if:
- The maintenance history is perfect
- All major repairs and recalls are documented
- The price reflects the extra risk and you budget for repairs
But it’s usually smarter to focus on the 2011–2012 EX35, especially later production units with fewer tech features.
