What are common problems with the 2018 911 Carrera 4S?

Question

Accepted Answer

The 2018 911 Carrera 4S is a solid car overall, but there are a few things to keep an eye on with the 991.2 generation:

**Coolant System** – This is the big one. The water pump and plastic coolant pipes are known weak points that can develop leaks over time. It's a fairly common issue across the 991 series, and replacement isn't cheap (often $2,000+ if the pump goes). Watch for "coolant system fault" warnings or any drips under the car.

**PDK Transmission** – Generally bulletproof, but some owners report rough shifting or hesitation, especially when cold. Usually fixed with a software update or a transmission service. Given this car only has 23k miles, it probably hasn't seen much wear yet.

**Fuel Injectors** – There are scattered reports of fuel injectors leaking slightly on cold starts (you might smell gas). Typically a warranty-era fix.

**General Rattles** – Trim and bodywork rattles are mentioned in buying guides—par for the course with a convertible that may have seen spirited driving!

**The Good News** – Unlike older 911s, the 9A2 twin-turbo engine in your 2018 *doesn't* suffer from IMS bearing or bore-scoring issues that plagued earlier generations. The turbos themselves are pretty robust too.

With just 23,655 miles and that "Original & Highly Original" condition, this particular car likely hasn't encountered many of these issues yet. Any questions about its service history, or would you like me to find some similar 911s for comparison?
