IMPORTANT SAFETY RECALL (Interim Notice)
2004-2005 Porsche Carrera GT
Porsche Recall APA3 / NHTSA ID 23V 241
Dea
This notice is sent to you in accordance with the National
Traffic and Motor Vehicle Safecy Act. Porsche has decided
that a defect, which relates to motor vehicle safety, exists
in certain 2004 to 2005 Model Year Porsche Carrera GT
Vehicles.
What is the issue?
On affected vehicles there is a possibility that the
spherical joints that connect the wishbone suspension on
the front and rear axles in the affected Carrera GT cars
may not meet Porsche’s service life durability
expectations. If these components are degraded, the
joints could break without warning, affecting vehicle
handling and increasing a risk of a crash.
What will Porsche do?
What should you do?
Porsche recommends, out of an abundance of
caution, to park your vehicle until the interim
inspection can be carried out.
If you need assistance arranging storage or
transporting your vehicle to the dealership for the
inspection, please contact customer support as
instructed below
To find your nearest authorized Porsche dealer, visit:
https:/ /www.porsche.com/usa/ dealersearch/
To help prevent this issue from occurring, Porsche is conducting a safety recall in two phases. In the first interim
phase, your Porsche dealer will inspect the subject suspension components. If any abnormalities are detected, you will
be advised not to drive the vehicle until the components can be replaced. If no abnormalities are detected, you can
continue to drive the vehicle until the components can be replaced. In the second phase your Porsche dealer will
replace the subject suspension components, free of charge.

APA3 Stop Use / Recall Campaign – Replacing Trailing
Arms on the front and rear axle
ID Number APA3
Models Carrera GT (980)
Model Years 2004-2005
VIN List Attached
Number of Affected VINs 479
Issue Description It was recently determined that the spherical joints
that connect the wishbone suspension components
on the front and rear axles in the affected Carrera GT
cars may not meet Porsche’s service life durability expectations.
What Dealers Should do PCNA intends to begin customer outreach as soon as
possible. Dealers should advise known Carrera GT
customers to have their vehicles inspected as soon as
the instruction are released. Towing should be encouraged.
What will Porsche do? The remedy will be conducted in two phases:
During the first phase (WPE0), the subject vehicles
will be inspected. If the inspection shows no abnormality
in the affected components, the vehicle can continue
to be used without restrictions until retrofit parts
are available. In rare instances, if abnormalities are
identified during the inspection, Porsche will advise
affected customers to discontinue driving their vehicle
until the part retrofit is completed.
APA3 Stop Use / Recall Campaign – Replacing Trailing Arms on the front and rear axle

During the second phase (APA3), all vehicles will be
retrofitted with new parts.
TI Number To be released at a later date.
Customer Letter To be posted at a later date.
Customer Reactive Statement We regularly monitor the quality of our products. As
part of this, we recently identified there is the potential,
in rare instances, that the spherical joints that
connect the wishbone suspension components on
the front and rear axles of the Carrera GT may be
susceptible to corrosion over prolonged periods of time.
Owners affected will be contacted in due course.
The remedial action – which will be carried out in
two phases, first an inspection, followed by later component
replacement will be carried out for free at the
owner’s convenience. This action is being taken with
an abundance of caution – no incidents attributed to
this concern have been reported.

Description of the Defect : It was recently determined that the spherical joints that connect the wishbone suspension components on the front and rear axles in the affected Carrera GT cars do not meet Porsche’s service life durability expectations.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : In the event of a wishbone or spherical joint breakage, vehicle controllability could be affected which could increase a risk of a crash.
Description of the Cause : The material used (X46Cr13) does not provide sufficient resistance to intergranular stress corrosion when exposed to salt and mechanical stress over service life. This could result in cracks or fractures in the spherical joints, and possible the wishbone. Identification of Any Warning
that can Occur : There is a possibility for perceptible noise and vibration due to loosening or failure of the connection, but component fracture could occur without sufficient warning.

Country : Germany Chronology :
In August 2019 the issue was presented for the first time due to an isolated case with one-sided broken spherical joints. The customer did not experience any abnormalities while driving the car. The damage was identified while the vehicles was in for unrelated service.
Further analyses were initiated to determine if this was a systemic issue or an isolated case. In October 2019 the remaining wishbones and spherical joints from the subject vehicle were analyzed. There were no further damages found in the car. During the following year, comparison vehicles were also obtained to analyze components on a vehicle without broken parts. These parts were difficult to procure due to the age and extremely limited production of the subject vehicle. The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-241
Page 3
The information contained in this report was submitted pursuant to 49 CFR §573
In October 22, 2020, a parts collection activity was undertaken to obtain exemplar parts from 20 in-service vehicles, to better understand the potential causes and the overall condition regarding potential (intergranular) corrosion.
The result was that no critical damage caused by corrosion to the examined components could be detected. No cracks or ruptures were detected. Markets with high use of road salt showed signs of increased normal surface corrosion, but all other analyses show unremarkable results.
Because the initial analysis was inconclusive, through all 2021 and the beginning of 2022 more parts were obtained and tested from other markets around the world.
Between November of 2022 and January 2023, material analyses results gave indications that the used material does not have enough corrosion resistance over the service life.
In February 2023 to March 2923, Porsche conducted additional driving tests / simulations in order to evaluate the potential driving behavior in case of a failure while driving. For this reason, a suitable simulation method and model had to be defined and validated.
On March 29, 2023, out of abundance of caution, Porsche decided to voluntarily recall the subject vehicles as described below.
Description of Remedy :
Description of Remedy Program : The campaign will be conducted in two phases. Due to unavailability of
parts, the subject components will first be inspected. If the inspection shows no abnormality in the affected components, the vehicle can continue to be used without restriction. Customers will be notified again when the remedy parts are available for retrofit. Should abnormalities be identified during the inspection, Porsche will advise customers not to use the vehicle until the retrofit is completed and will offer alternative transportation upon request.
The owner’s letter will advise that Porsche offers a reimbursement for pre- notification remedies in accordance with 49 CFR §573.13. How Remedy Component Differs from Recalled Component :
Identify How/When Recall Condition was Corrected in Production : The material of the recalled component is made of ‘X46Cr13”. The remedy component will be made of a more robust material (42CrMoS4).
Not applicable. Recall Schedule :
Description of Recall Schedule : Customers will be notified of the Recall within 60 days of the filing of this
report. If no remedy is available at 60 days an interim letter will be sent to customers, followed by a final notification when the remedy becomes available.
Planned Dealer Notification Date : APR 19, 2023 – APR 19, 2023
