Breakdown of the Porsche Cayenne’s Reliability Ratings

With a reliability rating of 1.5 out of 5, the Porsche Cayenne is ranked 14th among premium midsize SUVs. Poor ownership expenses are indicated by the $1,231 average yearly repair cost. You may anticipate more significant repairs for the Cayenne because both the frequency and severity of repairs are substantially higher than those for the normal vehicle.

Overall Reliability Scores: How Reliable Is the Porsche Cayenne?

The Porsche Cayenne’s overall reliability rating is 42, which indicates that it is not very reliable. The exact rankings of this car in relation to various other cars are shown in the chart below, however as a point of reference, the average overall rating is 57.

This information is based on a combination of looking at the cost and frequency of maintenance, warranty coverage, and long-term reliability by looking at how long these vehicles are normally kept on the road. Remember that the Porsche Cayenne is in the same class as other compact or subcompact vehicles, not only those in this comparison.

You may notice that these numbers differ significantly from those in J.D. Power or Consumer Reports. Most publications look at complaints made to the dealership within the first few months of ownership (like JD Power) or solicit biased feedback from owners regarding longer-term cycles of their new cars. Instead, this study examines data from wholesale auctions and repair businesses on actual repair prices and frequency.

Engine Reliability of the Porsche Cayenne

Base editions of the Cayenne were powered by 3.2-liter V6 engines created by Volkswagen beginning in 2003 and continuing until 2010. These lumps featured two cylinder banks sharing a single cylinder head, however they mostly consisted of VW parts despite the fact that the intake manifolds were exclusive to Porsche. They are referred to as VR6 engines, and a wide range of applications relied on them. The main known challenges for these power plants are timing chain and water pump troubles, but with routine maintenance, they can approach or surpass the 200,000-mile mark.

Plastic coolant pipes that were fractured in early Cayenne Turbo models with the 4.5-liter twin-turbo V8 engine caused coolant to flow onto the engine and cause it to overheat. These plastic pipes have mostly been replaced by metal versions. If you come across a model that still has the plastic coolant pipes, you should immediately replace them. The 4.8-liter engine that the Cayenne’s S, GTS, and Turbo acquired in 2008 did not have these difficulties, leaving only the coolant piping troubles.

The air/oil separator on the 4.8-liter engine is one item to watch out for (also known as the PVC valve). This is a component of the Porsche Cayenne’s emissions system, and when it malfunctions, it can cause anything from a slight inconvenience to a significant problem that needs to be fixed. You should keep an eye out for oil consumption, smoke coming from the exhaust pipes, a rough idle, and a corresponding check engine light when it begins to fail. If this component needs to be replaced, it won’t cost too much—it costs around $200.

Overall reliability for the first-generation Cayenne was evaluated at 3.5 out of 5 stars by U.S. News & World Report.

basis of the second generation Although they were larger at 3.6 liters, Cayenne models had V6 engines that were comparable to those in the first-gen cars. They had a comparable reputation for reliability with few issues and higher horsepower—296 as opposed to the 3.2-liter’s 250—thanks to the virtually identical architecture. Apart from the obvious increase in displacement, the main distinction between these two engines was the installation of direct injection.

For the Cayenne S, a twin-turbo 3.6-liter V6 was released in 2015. Porsche kept developing turbo technology, further optimizing the engines, and making them both incredibly dependable and powerful in the process.

According to WhatCar, certain automatic transmission faults were recorded for early second-gen cars, so it’s crucial to take one for a test drive before signing any paperwork. You should be on the lookout for harsh shifts, usually in second and third gear, as well as the gearbox occasionally briefly shifting out of gear when moving. Given that the Warner Aisin transmission was utilized, these gearbox problems are not specific to the Cayenne. These are notorious for having valve body failures that necessitate rebuilt units being changed, which usually comes with a heavy price tag of $1500-$2500 for parts and labor.

Finally, the 2019 model year marked the beginning of the third and current generation. Starting with the base 3.0 liter V6, all of the Cayenne’s engines are now turbocharged. Even after three years in production, this unit, which is shared by several Volkswagen models, appears to be holding up well. The same holds true for Porsche’s more potent models, such as the 2.9-liter twin-turbo V6 in the Cayenne GTS and the 4.0-liter twin-turbo V8 in the Turbo.

Typical Porsche Cayenne Issues

The Porsche Cayenne had a reliability rating of 1.5 out of 5.0 on RepairPal, placing it lowest among 14 high-end midsize SUVs. The following problems should be looked out for when purchasing a used Cayenne:

Engine issues – According to owners, the Cayenne’s engine is one of its worst flaws. The check engine light will typically illuminate, there will be loud noises, and the engine will typically cut off suddenly while moving through traffic. The standard solution is to completely replace the engine.
Drivetrain problems – When the drivetrain has troubles, the car may become unpredictable and difficult to handle. Many drivers have claimed that the drivetrain transfer case in their SUV has suddenly failed. Other sources described how the driveshaft eventually failed after losing its center bearings.
Problems with the coolant system were reported by several first-generation Cayenne owners, who mostly blamed the system’s plastic coolant pipes. The plastic coolant pipes apparently can’t withstand the extreme temperatures and will crack or spill. Other crucial components could be harmed by the coolant leak.
Owners who experienced a failed startup stated that the Cayenne’s gasoline pump was prone to malfunction. A damaged fuel pump could cause a no-start or stalling situation and need to be replaced.

One of the best purchases you can make is a used or CPO luxury car since you can get a lot of car for not a lot of money. A three-year-old premium car may be found for around half of what it would cost new. To get the greatest offers, look through this list of the top used luxury vehicles.

Volkswagen Cayenne

Acceleration is strong with the base 3.0-liter V6 turbo engine once it gets going, but the Cayenne exhibits some initial lag off the line and the harsh engine stop/start feature detracts from smoothness.

There are also two hybrid models, a coupe body style, and the Turbo S E-Hybrid, which offers a combined 670 horsepower from a 4.0-liter twin-turbo V8 engine and an electric motor.

The updated Cayenne features new entertainment and driving assistance systems with new linked technologies based on cloud computing, sharing fundamental components with the majority of new Audi cars.

Blind spot warning is an option, however forward collision warning and automatic emergency braking are both standard.

The Cayenne became one of the sportiest, most nimble SUVs available after a thorough overhaul in 2011.

All variants, including the hybrid, V6, V8, turbo V8, and V8 versions, have a smooth eight-speed automatic transmission.

Be aware, though, that the diesel was under investigation in 2016 for potential cheating on emissions testing. Before you buy, make sure it passes smog.

At slower speeds, the ride is a little stiff, but as you accelerate up, it becomes smooth and controllable.

Outstanding steering, handling, and braking help the over-the-road dynamics to remain among the best in the class.

Some people may find the controls to be too confusing, but the Cayenne appears to be just as opulent as it is powerful.

Locks on the center, rear, and low range differentials improve off-road capability.
