Our known issues database covers the 2003-2025 Porsche Cayenne with 16 documented issues documented across 12,500+ owner reports.
The plastic coolant distribution pipes in the Cayenne V8 and VR6 engines crack and leak, particularly the pipes routed between the cylinder banks under the intake manifold. The plastic becomes brittle from heat exposure and can fail suddenly, causing rapid coolant loss and overhe… Repairs typically run $1,200-$3,000. Severity: high.
Cayenne models equipped with PASM air suspension suffer from compressor burnout and air strut bladder leaks. The compressor overworks to compensate for leaking struts, eventually overheating and failing. Air strut bladders crack from age, UV, and road debris, causing the vehicle… Repairs typically run $1,500-$4,500. Severity: high.
The timing chains on the Cayenne V8 and VR6 engines stretch over time, and the hydraulic tensioners lose effectiveness. On the V8, the timing system is at the rear of the engine, making repair extremely labor-intensive. Chain stretch leads to retarded timing, rough running, and e… Repairs typically run $4,000-$9,000. Severity: high.
The transfer case on the Cayenne is prone to output shaft seal leaks and internal bearing wear. Low fluid levels from undetected leaks accelerate internal damage, leading to grinding noises and eventual transfer case failure. The Turbo and GTS models with higher torque loads fail… Repairs typically run $2,000-$5,000. Severity: high.
A supplier used cracked raw material in the forging process for the driver's side front axle upper left control arm on a short run of 9YB Cayennes built 9 May to 19 June 2024. The arm can therefore leave the factory already cracked, and a break in service impairs wheel guidance a… Repairs typically run $0-$0. Severity: high.
Porsche AH10 / NHTSA 17V576 covers certain 2003–2006 Cayenne S/Turbo, 2004–2006 Cayenne and 2006 Cayenne S Titanium Edition vehicles, totaling 50,145 in the US filing.

Recall 16V169 / Porsche AG02 covers certain 2011–2016 Cayenne vehicles built April 28, 2010–January 11, 2016. A retaining circlip may have been pulled off during preassembly. The pivot pin can then move, reducing the pedal's lateral support; continued operation can damage the hin… Repairs typically run $0-$0. Severity: high.
Porsche AKB1 / NHTSA 19V446 addresses a selector-cable bushing whose material can deteriorate and detach. The selected lever position may then differ from the engaged transmission range. The lever can be placed in Park and the key removed while the transmission is not in Park, wi… Repairs typically run $0-$0. Severity: high.
US recall 21V493 / Porsche AMB4 concerns 27 specified 2021 Cayenne vehicles built May 23–June 23, 2021. A production-process error may leave the steering-column-to-steering-gear screw connection outside specification. It can separate and cause deterioration or loss of steering co… Repairs typically run $0-$0. Severity: high.
A batch of turbochargers was built with turbine wheels carrying a casting defect. The wheel can fracture in service; performance drops away first, and the turbine shaft can then fracture, at which point engine oil is drawn through the failed bearing into the exhaust system, produ… Repairs typically run $0-$0. Severity: high.
The catalytic converters on 958-generation Cayennes fail prematurely due to substrate breakdown and thermal degradation. The V8 models with four cats are especially expensive to repair. Failed converters trigger check engine lights and cause the vehicle to fail emissions testing. Repairs typically run $2,000-$6,000. Severity: medium.
The PDCC active anti-roll bar system uses high-pressure hydraulic fluid to control body roll. The hydraulic lines, actuators, and seals develop leaks over time, causing the system to lose pressure and trigger fault codes. Repair costs are extremely high due to the specialized com… Repairs typically run $2,000-$6,000. Severity: medium.
The coolant lines feeding the turbochargers on the Cayenne Turbo and Turbo S develop leaks at the crimped fittings and rubber sections. High underhood temperatures accelerate rubber degradation.
