What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Two days ago smelled strong raw gas smell and immediately took to Porsche Hawthorne and they confirmed leak in fuel line which as I am reading seem more common and very concerning due to risk of fire - appears a know thing amongst Porsche yet they donât do anything preventatively about it.
On XXX, less than 24 hours after an authorized Porsche dealer released this 2024 911 as a successfully completed repair with the diagnostic codes cleared and no root cause documented, the vehicle suddenly lost motive power while traveling at highway speed.
Woke up one morning and noticed a very strong gas smell coming from the car while driving with the windows down, even at low speed. Once I noticed the smell I stopped driving and exited the vehicle and again noted the very strong smell. I immediately took the car to the [dealer] Beverly Hills.
The glass sunroof exploded out while driving on the road, there were no other cars driving ahead of me as I was on a highway onramp. The car is current at the dealership pending repair. The glass exploded outward and could have hit a car following. The car has been inspected by the dealer and insurance company.
The contact received notification of NHTSA Campaign Number: 24V809000 (Wheels); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair.
Heard a ticking noise while driving. Pulled over, on freeway. It was not a safe situation parked on side of a major freeway. Turned off car to look around the engine and found nothing. Started the car again and it died within 5 seconds. The electric system completely died after and would not crank.
