| Suspension problems |
The ride height sensor on the right front suspension is mounted to the upper control arm via a plastic bolt and bracket. This plastic mounting component failed under normal driving conditions. The failure caused the ride height sensor to malfunction, which directly affects the vehicle's air suspension system and its ability to maintain proper ride height and handling characteristics. When driving, I received multiple chassis height warning messages stating that the chassis was too high or too low or malfunctioning. The ride height sensor is a critical component of the Porsche active suspension management (pasm) system. Its failure can result - incorrect suspension height, affecting vehicle stability and handling - suspension system faults that may trigger unexpected warning conditions while driving - potential loss of driver control in the event of sudden sensor failure at highway speeds this failure is not isolated to my vehicle. A review of Porsche owner forums including rennlist and 6speedonline reveals similar plastic mount failures on the ride height sensor across multiple Porsche platforms, including the cayenne, macan, and Panamera. The fact that Porsche has since revised the replacement hardware from plastic to metal strongly implies the manufacturer is aware the original design was inadequate. However, no recall or technical service bulletin has been issued to proactively notify owners or provide a remedy at no cost. When the plastic bolt and bracket failed on my vehicle, my dealership replaced it with the current Porsche-supplied metal replacement hardware because the plastic parts have been discontinued. However, the updated metal bolt and bracket are physically incompatible with the existing control arm, requiring the control arm to also be replaced. Owners who are unaware of this incompatibility may drive vehicles with an improperly secured or non-functional ride height sensor, increasing safety risk.
Coolant warning light on - seeing leak coolant warning light for coolant level comes on. Seeing a leak at a hose. Leaking at coolant bypass hose under intake. Coolant pipes in thermostat housing are coming loose at the epoxy joint. Chassis system failure, the car will stop abruptly on roads. And if here's that these problems that are reoccurring have been recalls before, that have not been addressed.
I purchased the above-referenced car in July 2020 almost immediately after purchase the indicator light came on with chasis failure and the car lowered to a safe distance to the ground. Unbeknownst to me the car had been declared unsafe to drive previously. The airbags had been deployed and placed backward the front sensors were painted over and not operable. I had to take legal action against four years later the dealer who ended up reselling the car in 2021 for more money. No reporting of these documented problems.
