Common Porsche Cayenne Problems

Below are some common Porsche Cayenne issues that need attention to make an effective preventative maintenance routine to avoid costly repairs:

1. Cooling System Issues

Most Porsche Cayenne SUVs have cooling system problems, as their V8 engines have plastic cooling tubes.

The tubes melt when the engine overheats, causing coolant leaks, engine starter problems, and engine death.

Repairing the broken plastic coolant line can cost around $3500. However, you can prevent this problem by protecting the engine from overheating.

2. Engine Died

Most automobile problems eventually cause the engine to die. Though it takes time, ignoring the overheating engine is the key reason.

Porsche Cayenne’s engine may overheat due to an overflow of coolant, a coolant leak, a faulty radiator fan, or a failed thermostat.

The common symptoms include activating the check engine light, the engine shutting off abruptly and making a loud noise. Replacing the Porsche Cayenne’s dead engine may cost around $1100.

3. Malfunction of PCM

Porsche PCM is another major issue that hasn’t been resolved today. Porsche Cayenne, particularly the 2016 model, experiences the PCM random rebooting problem most. The user finds that the PCM reboots itself randomly after a few minutes of turning on the engine.

In other words, the music may stop suddenly and start again after 10 to 15 minutes, and it may keep repeating. This problem is common for both old and new Porsche Cayenne models.

The PCM reboot problem can occur after Sirius FM sends out an update. Using the incompatible aftermarket PCM can also cause this problem. 

To fix this problem, press and hold the PCM button for around 10 seconds or until the PCM starts rebooting.  Then follow these steps:

Select PCM CAR > OPTION > Set PCM System > Reset PCM > Vehicle Handover > Yes > Yes

If you need to replace the PCM to solve the issue, it’ll cost around $3,090.

4. Drivetrain Problem

The issue with the Porsche Cayenne’s drivetrain can make the SUV erratic and uncontrollable. Some users complain that its drivetrain transfer case fails without showing any warning sign. The drivetrain may also eventually lose its center bearing and die.

5. Transmission Problems

According to the user’s complaints, the Porsche Cayenne’s transmission experiences various issues, including gear problems, excessive vibrations and shakes, strange noise or odor, and fluid leaks. Each problem requires unique treatment.

For example, if you experience slower gear changing than usual or gear slippage, you’ll have to replace the gearbox, which will cost around $1,800 to $3,400.

But if your SUV shakes while shifting gears from neutral to other, you may need to top up transmission fluid or change the faulty transmission part.

You may also hear a grinding or humming noise when your Porsche is in neutral. It can also happen if the bearing becomes loose. The burning smell can result from frayed cables or overheating belts, which are cheaper to replace.

Lastly, the broken transmission may cause fluid leaks, and noticing a brown or red pool after parking the car indicates it. If so, you must repair the leak to restore the transmission’s functionality.

6. Brake System

Premature brake wear is another common Porsche Cayenne problem that can occur after driving only 20,000 miles. Replacing the brake system of a Porsche Cayenne can cost around $605 and $837.

However, you can avoid this expensive repair cost by routinely checking the brake pads’ condition. You should also check the brake fluid level regularly to avoid wear out.

7. Fuel Pump Issues

The newer Porsche Cayenne is designed with high-pressure fuel pumps, while older models have low-pressure ones.

The low-pressure fuel pump overheats over time and shuts off the fuel pump. The newer one can also fail due to the damaged pump valve.

It can cause reduced fuel economy, weaker engine performance, whining noise, engine stalling, or difficulty turning on the engine.

To fix this issue, you have to change the fuel tank, which will cost between $3,697 and $4,000.

Is the Porsche Cayenne a Good Car?

The Porsche Cayenne is a highly popular luxury sports car. However, it is a bit expensive to buy and maintain. The SUVs are well-engineered, run fast, and are efficient to handle.

The Porsche Cayenne also has excellent off-road capabilities. Many car enthusiasts consider the Porsche Cayenne a legit alternative to the Jeep SUV and Range Rover. 

Its 18-way adjustable seats are perfect for long legs and make long road trips comfortable. In terms of reliability, the Porsche Cayenne receives 81 out of 100 from J.D. Power. U.S. News and World Report rated this car 3.5 out of 5.

Though the Cayenne experiences some problems, its durable gearboxes and engines last a long time, making it highly dependable.

If you plan to buy an old Cayenne, remember to check the acceleration, oil, and braking system. Cayenne’s average annual maintenance cost is around $1,231, which is higher than most SUVs.

Are Porsche Cayennes Expensive To Run?

Yes, Porsche Cayennes are expensive to own for many reasons. First, they are high-end luxury SUVs, so their parts are expensive.

Second, they get only specific maintenance, so removing the oil is a complete oil change, which will cost from $200$ to $250$, not including the labor if you don’t do it yourself.

Third, there is regular maintenance, like fixing coolant leaks or replacing the transfer case, which can be expensive because they can cost more than $2000.
​
On top of that, older models can be plagued by engine and brake wear, which also raises operating expenses.

Cayennes aren’t thrifty in terms of fuel economy, either: the car needs premium gasoline to run efficiently, a cost that only increases over time.

Maintenance and repair costs ramp up as your Cayenne ages, especially for cars with complex electronics and air suspensions.
