Coolant Leak

If your Cayenne is leaking coolant fluid, be sure to get it fixed right away. Coolant system leaks can lead to engine failure costing thousands of dollars to repair. A common cause of Cayenne coolant leak is a failed radiator hose.

Make sure the repair shop uses molded, Porsche specific replacement hoses. Universal hoses often become deformed and fail easier. Have the hose clamps replaced as well.

Cayenne radiator hose replacement typically costs around $120 – $160, parts and labor.

Brake Job

If you notice squeaking or grinding at low speeds, it’s probably your vehicle’s brakes. Replace worn pads promptly to avoid wear or damage to the brake rotors. Braking power might also diminish with worn out brake pads.

The cost of Porsche Cayenne brake pad and rotor replacement is between $300 – $400. Parts alone cost around $150 – $200.

Leaky Oil

If you notice oil under the engine it could be your Cayenne’s oil pan. The oil pan rests at the bottom of the engine so you won’t see any oil on top. In most cases, a leaky oil pan won’t cause any problems in short term vehicle performance. Still, get it fixed right away to avoid serious problems later.

Porsche Cayenne oil pan reseal is fairly expensive, costing between $1700 – $2300. Labor costs alone on this repair can be up to $1000 or more. If your Porsche factory warranty is still good, your expenses are covered. Some owners opt for an extended car warranty to cover repair costs after the factory warranty expires.


If your Cayenne engine begins to misfire or hesitate, it could be the fuel injectors. In most cases, the check engine light and other alerts might appear as well. Additionally, you might notice rough idling or even a strong gasoline smell.

Repair costs for a Porsche Cayenne fuel injector runs around $400 – $590. This is the price for one fuel injector replacement, but you may have to replace more than one.

Dead Alternator

If your Cayenne won’t start, check the battery first. When you take your vehicle to the shop, they’ll also test the alternator. If the battery is healthy, it could be the alternator doesn’t charge sufficiently. You may also notice dimming of the headlights or interior lights.

Porsche Cayenne alternator replacement costs range from $890 – $1460. The parts alone for this repair cost around $1200.
