Do Porsche Cayennes Have A Lot Of Problems?

The 2004 Cayenne Turbo 4.5L owners all have the same issue. Plastic coolant lines that run down the middle of the engine blocks are employed in this model. The plastic cannot resist the tremendous temperature produced by the engine. The pipes frequently melt, causing coolant leaks and safety issues. Also impacted is the starter, which is situated underneath the coolant pipes.

Customers assert that despite knowing about the issue, Porsche has not yet issued a recall. Dealers for Porsche advise replacing the plastic with an aluminum pipe kit. The manufacturer does not cover the estimated $3,500 cost of fixing this issue.

It seems that this issue with the coolant lines is not specific to the 2004 model. A class-action lawsuit was brought against Porsche in February 2020. Owners of every Porsche Cayenne V8 from model years 2011 to 2019 are the plaintiffs.

Concerns about the epoxy used to bond the plastic coolant pipes are addressed in the lawsuit. Even under normal driving conditions, the adhesive tends to deteriorate over time. When the pipes separate, the engine fails, leaving the user without power right away. Unexpectedly, the vehicle stops moving. Additionally, when coolant leaks onto the tires, a dangerous traffic hazard is produced. These claims are being looked upon by the NHTSA.

Issues with Porsche Communication Management (PCM)

Symptoms include the Cayenne PCM unit restarting every two to three minutes, a map that won’t load and that loads only the Porsche logo screen in the wrong language.

Numerous Cayenne owners have complained about a variety of strange and erratic PCM system behavior, with PCM3.1 appearing to be the biggest offender. Many people are certain that unstable working circumstances were caused by a software upgrade. For a sizable number of owners, it does appear that the reported difficulties started at roughly the same time. Nobody is entirely certain of the precise etiology, yet a totally healthy PCM might suddenly display the most bizarre behavior, as shown in the symptoms above.

First, the device itself may malfunction electrically or physically, just like anything else. Instead of the loss of a specific feature or odd behavior of the PCM unit, this usually results in the complete loss of functionality of the entire PCM unit. Although there are some third parties all around the world who have started to fix the unit, replacing the PCM is typically the only option in this situation. Dealers have no choice but to replace because the expense is rather expensive.

An old-fashioned Ctrl Alt Del tends to cure the majority of issues for the second group of Cayenne PCM problems, which typically belong into the weird behavior category. Some may recall the days when it was essential to perform this action several times daily on a Windows PC, but in this case, the PCM typically recovers nicely to a starting point and then continues to work normally.

You should be aware that what you are doing here is returning the system to its initial factory settings, which were set before Cayenne was given to its first customer. All of your custom settings will be lost, but this is a tiny price to pay compared to the expense of replacement, which incidentally will also mean losing all of your custom settings!

Epoxy or Plastic Coolant Line Failure

Porsche decided to use plastic coolant pipes in the Cayenne engines for some unknown reason. There is a lawsuit filed against Porsche specifically for all V8 958 Cayenne models from 2011 to 2019. Coolant pipes transport coolant from the radiator to the engine’s hotter area and back to the radiator to cool off before repeating the procedure.

The area below the intake manifold, where the coolant lines are located, is not the coldest location for plastic parts. Due of the prolonged exposure to heat, epoxy and pipes frequently fail. If either of them fails—the epoxy or the pipes—steam will probably start to come out of the engine, and the engine may then shut off.

Why do Porsches lose so much value?

The Cayenne SUV is possibly Porsche’s most innovative vehicle—aside from the 911. Porsche’s desire to extend its production line led to the Cayenne, which was released to much fanfare.

The company’s decision to develop an SUV was criticized by Porsche purists, and detractors watched to see if the Cayenne would be a commercial failure.

To the dismay of Porsche enthusiasts, many people found the Cayenne to be appealing due to the model’s luxury, comfort, and performance. Since then, the Cayenne has surpassed the Macan as one of Porsche’s second-best-selling vehicles.

Despite its strengths, the Cayenne is the second-worst-selling Porsche model. One of the Porsche models with the fastest depreciation rates on the market, with a three-year depreciation rate of 44.84%.

Many explanations have been put forth by experts for the Cayenne’s appalling depreciation rate. One is that there are now more used models available to purchasers as a result of the model’s popularity. Used car values decline and the rate of depreciation on new models rises as supply outpaces demand.

The Cayenne’s status as a luxury SUV is another possible explanation for its significant depreciation.

German luxury vehicles [sedans, SUVs, etc.] frequently depreciate more quickly than the majority of cars, which has an impact on resale value.

Because there is less demand for the Cayenne because it is more expensive to maintain, new versions depreciate more quickly than usual. Additionally, used car purchasers do not want to spend money on dated luxury cars, thus there is still a minimal market for these automobiles. Increased depreciation on new vehicles and decreased resale values for used models result from this.

Even though it is the lowest for a Porsche, the Cayenne’s depreciation rate is among the best in the luxury SUV market. In fact, the Cayenne was named the finest midsize two-row SUV with the highest resale value in the 2020 KBB Best Resale Value Awards.
