How do I detect 2008 Infiniti G35 catalytic converter problems?

I just took my 2008 Infiniti G35 to a repair shop because the car wasn’t accelerating as quickly as it usually does. They told me it would cost $1,800! Does the 2008 Infiniti G35 have ‘catalytic converter’ problems? And how do you tell if it does?

I’m sorry to hear about this costly repair bill. There’s nothing more frustrating than unexpectedly having nearly $2,000 in expenses to suddenly worry about!
Your
Infiniti G35’s
catalytic converter is a part of the exhaust system. It’s there to remove harmful gasses from the car’s exhaust before they leave the car as extremely dangerous for humans and the environment.
Catalytic converters usually last 80,000 to 100,000 miles. But no car part is indestructible. Catalytic converters can wear down, clog up, and get damaged while driving. When that happens, you’ll notice some of these symptoms:
  • The check engine light will come on to warn you of an issue.
  • The car’s acceleration dips. When exhaust has a hard time escaping the car, the engine won’t perform as it should.
  • The fuel economy takes a hit because the exhaust isn’t getting out of the car properly.
  • The car’s exhaust will get smelly, and that’s the one you need to worry about most. It means you’re breathing in dangerous gasses, and you should get this fixed pronto!
For a 2008 Infiniti G35, replacing the catalytic converter should cost around $1,600 to $1,700. If you’d like to find a lower rate, you best option is to get a second opinion and shop around.
