There are 4 owner-reported fuel system complaints for the 2022 Porsche 911in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Metallic Fuel line located on top of the engine suddenly started leaking. Previous time I drove the car there was no indication of a gasoline leak or odor. There were no warnings or indications of an impending leak until gasoline was emitted from the line. Fortunately when the leak started I was only driving locally and upon returning to my house a raw gasoline odor was apparent at the back of the car. Had I been driving up to Monterey which is a 6 hr. drive I’ve done several times before a gasoline leak over the engine would of likely caused a fire that would have been extremely hazardous. The car was towed into the dealer as it was not even safe for a 5 mile drive. The dealer reported they are seeing many cars with the safe defect. Also this issue has been reported on [XXX] a Porsche enthusiast car forum. [XXX] The dealer corrected the problem and the manufactured is aware. Fortunately for me it occurred before the warranty expires in a few months otherwise the repair cost would of been $12,000 as they must drop the entire engine to access and replace this line.

String gas odor while driving. Upon inspection it was determined that a fuel line was leaking on top of the engine which requires an engine out repair. There are several other people discussing the same issue of Rennlist.com a Porsche enthusiast site. Seems to be a problem.
A leak in a high pressure fuel line was releasing gas on top of the motor. I smelled gas, and had vehicle towed to the dealership where I purchased the car. The dealership has confirmed the cause of the fuel leak and ordered the replacement fuel line. Since it’s a leak in this fuel line, NO check engine lights or other warnings flagged the problem. In my opinion, this is a significant safety problem that could lead to a fire and potential injury.
Massive fuel leak. Appears to be fairly common amongst other owners. Required engine out to repair.
