Is the 2017 Porsche 911 recalled in the UK or Europe?
Recalls issued by the UK's DVSA and through the EU's Safety Gate system that cover this model and build period. European models can differ from U.S. ones, and "years estimated" means the recall gave no build dates, so confirm your own car with your registration or VIN.
UK DVSAThe airbag sensors in the side members on the vehicle may not be screwed tightly enough
Risk: There is a possibility that the side airbag sensors are not tightened to specification.
Fix: Check both side airbag sensors and rework the fixing where necessary.
UK DVSAIncorrect detonators fitted to front passenger airbags
Risk: Incorrect passenger air bag detonators were installed during manufacturer. this may adversely affect the airbag's deployment in the event of an impact.
Fix: On affected vehicles replace the passenger's air bag module.
UK DVSABonding on windscreen is insufficient
Risk: On 911 Cabriolet and Targa models only the windscreen may have been fitted with insufficient bonding product. There is a possibility that the windscreen could detach from the vehicle in the event of an accident.
Fix: Recall the likely affected vehicles and rebond the windscreen.
UK DVSAFuel injection pipes may become insecure
Risk: The screws retaining the fuel collection pipe(s) may shear under stress. This may allow the pipe(s) to separate from the injector(s) and cause fuel to leak.
Fix: On affected vehicle replace the collection pipes' securing screws
UK DVSAFuel may leak
Risk: The high fuel pressure that builds up in the injection system when the engine is running can cause cracking and ultimately press the relevant fuel collection pipe off the injectors. This can cause a fuel leak in the engine compartment.
Fix: Recall the vehicles that are likely to be affected and replace the fastening screws for the fuel collection pipes with different screws.
UK DVSAFront side airbags may be impaired
Risk: It has been identified that the front side airbags may have been fitted with the incorrect detonators. If the vehicle is involved in a collision then the airbags may not operate as intended.
Fix: Recall all affected vehicles to replace the front side airbags with a quality assured replacement.
UK DVSAReduced brake performance
Risk: A vacuum supply line for the brake booster may not have been fitted correctly. The vacuum supply line could become loose resulting in reduced braking assistance. The brakes will still work but the driver will have to supply additional input for the required brake effort.
Fix: Recall the vehicles that are likely to be affected where the connection points of the vacuum supply line will be checked/adjusted/replaced as necessary.

On the day of delivery of this Porsche Approved Certified Pre-Owned vehicle (purchased May 24, 2022, from Porsche Nashua, Nashua, NH), traction control and all-wheel-drive warnings appeared on the drive home from the dealership. The valve lift solenoid/actuator was replaced under warranty; the vehicle spent 7 days in the shop. Within four months (September 2022), the engine fault light returned and the engine had to be dropped for repair (fuel tank breather pipe replacement and DME reprogramming) — 13 more days in the shop. A certified vehicle should not suffer stability/drivetrain faults on…
Check left rear light warning light came up. Took car to mechanic when the light housing was removed it broke into pieces. Mechanic stated 2 others in the past month had the same issue. Issue comes from heat and improper shielding makes the housing britle. Car has 19k miles only. Over $1500 to repair.
While driving 40 miles per hour a sudden explosion happened with no warning. Thought it was the engine due to the smoke coming out of rear of the vehicle but realized that engine was still on and steam was coming out. All coolant drained out of vehicle and on road. Vehicle was towed to a Porsche dealership in Duluth Ga. The coolant tank exploded causing minor body damage and sudden loss of all coolant. The dealer replaced the shattered coolant tank but found no cause as to why the pressure got so high to cause the tank to explode. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT…
The rear window seal is severely breaking apart, severely cracked and others are melting. This may affect condensation inside the vehicle and potentially be a safety hazard. Several reports on this problem can be seen at porsche forums. I believe this is a manufacturing defect and is a potential safety hazard on many porsche vehicles.
My air conditioner/heater fan does not come on after car has been sitting for a few days in a humid climate. This problem is documented with a temporary fix on the static.nhsta.gov site. https://static.nhtsa.gov/odi/tsbs/2021/MC-10186302-0001.pdf The problem is it happens to me every week or so. There is no permanent fix. This is a safety issue because without the fan motor the defroster doesn't work and the windows can fog up creating a dangerous situation.
