7 Common Infiniti Repair Issues and How to Fix Them

If you have an Infiniti car, you truly are living a luxurious life. They are beautiful, reliable, and perfect for any ride you want. However, like all cars, certain car repair issues pop up from time to time.

The more time you spend on the road, the more likely you are to face these concerns. So what are some common Infiniti repair issues to watch out for regularly? And how do you fix them?

Luckily, we’ve put together a guide to let you know exactly what to look out for. Let’s dive in!

Faulty Spark Plugs

Faulty spark plugs in an Infiniti are surprisingly common. Fortunately, this is a relatively easy and inexpensive repair. To do this, you can begin by identifying which spark plugs are faulty.

With the help of a tech manual and some knowledge about how engines work, you can replace the spark plugs yourself. Otherwise, you can take your vehicle to your local Infiniti mechanic.

Once you have identified which ones need to be replaced, you can purchase them from stores that sell auto parts and complete the replacement yourself. Next, insert the new spark plugs and reconnect them with the proper cables and fittings and you’re done!

However, you need to make sure that you’re using the correct type for your particular Infiniti models, as compatibility is key. 

Noisy Brake Pads

Noisy brake pads are another common issue with Infiniti vehicles. The source of the noise is usually caused by pads that have been worn down past their safe point and are now scraping against the rotor or caliper.

To fix the issue, you’ll need to replace your brake pads. This is a relatively easy process and can be done at home with the help of some basic tools. Start by removing the wheel, the corroded and worn-out caliper, and the brake pad.

Now insert the new brake pad and caliper when re-installing. Be sure to lubricate all the links so that the new brake pad will move freely.

Finally, retighten the connections and re-install the wheel. This should help reduce or eliminate the noise caused by the worn brake pads.

Catalytic Converter Failures

Catalytic converter failures are a common issue with Infiniti cars. This is typically caused by a malfunctioning oxygen sensor or an issue with the mass air flow sensor.

While oxygen and MAF sensor repairs can be more economical solutions, replacing the catalytic converter is the surest way to restore power and performance. To replace it, a reputable repair shop will need to have access to the vehicle.

They will then inspect the catalytic converter to make sure it is the problem. After verifying, they will:

  • Remove the old converter
  • Install the new one
  • Reset the O2 sensor

Once the restorations are made, the vehicle will need to be tested to ensure the repairs are up to standard. With proper care and maintenance, the new converter will restore power and fuel efficiency, and prevent future problems.

Worn Out Shocks and Struts

Worn-out shocks and struts are common issues with Infiniti repair. Signs of a worn shock and strut include poor handling, less precise steering, and uneven tire wear.

When replacing them, it’s crucial to select the correct replacement parts that are custom-fit for the vehicle. Having them professionally installed can also ensure a quality repair.

Additionally, air shocks and struts can also be replaced with specially formulated shock and strut oils which can be purchased from auto-parts stores. They can also be replaced by:

  • Inspecting and replacing the worn parts
  • Adjusting for proper alignment
  • Modifying the suspension for proper ride and quality

All of these will ensure safe driving and a comfortable ride for the driver and passengers.

Brake Lights Going Dim

If your Infiniti brake lights appear to be dimming, there are a few common causes that can be easily fixed. One issue that could be causing it may include:

  • Burned out or corroded bulbs
  • Loose bulb sockets or wiring
  • A damaged fuse
  • Poor grounded connections

Additionally, faulty relays and bad switch assemblies can also result in non-operational brake lights. To fix the issue, you can try to clean the connections or replace any loose parts to fix the problem.

If necessary, it may be best to replace the bulbs or switch assemblies. Lastly, checking the relays and ground links is also critical to ensure proper brake light operation.

Ultimately, a few minutes of time and careful attention to the repair job can have the brake lights back to a safe working order.

Catalytic Converter Failures

The first cause is that the bulbs need replacing, and can be easily bought at any auto parts store that your Infiniti model uses. 

Another common cause is that the brake light switch is not functioning properly. If this is the case, you can just replace it with a compatible one.

If neither of these solutions works, then the wiring system of your car needs to be inspected for any electrical issues. When in doubt, always seek the help of a professional mechanic to ensure that your Infiniti is repaired properly and safely.

Engine Coolant Leaks

The engine coolant leak is another usual Infiniti repair issue. This can be caused by several things ranging from:

  • A puncture in the coolant hose
  • A cracked radiator
  • A faulty water pump
  • A blown head gasket

Depending on the severity of the leak, the repair may be as simple as replacing a hose or as complicated as changing the head gasket. In some cases, it may be necessary to perform a chemical or pressure test to determine the source of the drip.

Furthermore, be sure to flush the system, fill it with fresh coolant, and check for leaks. Ultimately, be sure to replace the coolant every two years to ensure ongoing engine health.

If the engine continues to leak or overheat, it is recommended to bring the vehicle to an Infiniti-certified technician who can use specialized diagnostic machinery to accurately identify and remedy the problem.

Infiniti owners can take comfort that their vehicles are reliable and require minimal service. These issues can be fixed with relative ease, either on your own or by a certified Infiniti dealer.
