5 Signs Your Porsche 991 Needs a Repair

5 Most Common Porsche 991 Repairs

Porsche 991 owners understand (or will soon learn to understand) that these vehicles are not perfect. Whether you’re cruising along the scenic Niagara Parkway, exploring the charming towns of Stratford and Elora, or hitting the scenic route in the Thousand Islands, you want your Porsche to perform at its best. That’s why servicing your Porsche 991 is necessary.


Porsche repairs may be needed after a couple of months or years of ownership depending on the way you drive it. Here are X common Porsche 911 991 repairs you need to know, and how to prevent them from happening.


1. Oil Leaks

One of the most common issues that Porsche 991 owners face is oil leaks. Oil leaks can occur from various places:


  • valve cover gaskets

  • oil filter housing

  • oil pan gasket

  • rear main seal


Oil leaks can cause engine damage, performance issues, and environmental problems. For prevention, check your oil level regularly and look for signs of leaks under your car. You should also change your oil and filter every 16,000 km or once a year, whichever comes first. If you notice any oil leaks bring it to a specialist Porsche mechanic as soon as possible.


2. Water Pump Failure

Another common problem that can affect your Porsche 991 is water pump failure. The water pump is responsible for circulating coolant throughout the engine and keeping it from overheating. If the water pump fails, it can cause the engine to overheat.


Some signs of water pump failure include coolant leaks, engine overheating, steam coming from the hood, or whining noise from the engine. Get a Porsche specialist to check your coolant regularly for signs of leaks or corrosion. You should also replace your water pump every 100,000 km or as recommended by your Porsche mechanic. Chariots of Simcoe Porsche repairs for this issue are often due to the aluminum corrosion on the coolant hose.

3. Spark Plug and Ignition Coil Failure


Porsche spark plugs and ignition coils are essential for creating the spark that ignites the fuel-air mixture in the cylinders. If they fail, it can cause:


  • misfires

  • rough idling

  • poor acceleration

  • reduced fuel economy

  • increased emissions


Some signs of spark plug and ignition coil failure include:


  • check engine light

  • engine misfire codes

  • rough running

  • difficulty starting


To prevent spark plug and ignition coil failure, you should replace your spark plugs every 50,000 km, 3 years, or as recommended by your Porsche specialist.



4. Brake Pad and Rotor Wear

Some signs of brake pad and rotor wear include squeaking or grinding noises when braking, vibration, or pulsation when braking, longer stopping distances, or brake warning light. To prevent brake pad and rotor wear keep up with regularly scheduled maintenance at a Porsche mechanic shop near you like Chariots of Simcoe.


5. Air Filter Replacement

This is an honorable mention from the Porsche mechanics at Chariots of Simcoe. Replacing a Porsche air filter can sometimes cost upwards of $400 alone due to poor design choices made by Porsche. Replacing the housing and air filter units often involve dealing with rusted or damaged screws, and an insane number of bolts to unscrew and screw back on, and the air filters are not cheap!
