Is the Porsche 911 GT3 reliable?
Overall, the 991.2-generation GT3 is a reliable car and far more durable than the pre-facelift model it replaced.
Early 991 GT3s were at risk of catching fire due to an issue relating to the engine's connecting rods, and after a number of incidents, Porsche recalled all cars to rectify the problems that afflicted the 3.8-litre unit.
While the 4.0-litre engine isn't totally free of faults, it is much more robust thanks to its use of stronger materials – many owners have covered big miles without fault.
Considering how highly strung the engine is, we'd recommend a full Porsche warranty for peace of mind.
Engine: The 4.0-litre is far more robust than the 3.8-litre unit, but there have been a few cases of engine failure, variously attributed to causes such as oil starvation or low cylinder compression. Porsche often covers engines under warranty, but be sure to check the service history.
Gearbox: Issues with both the manual and PDK ’boxes are rare but make sure gearshifts are smooth because a replacement for either is obscenely expensive.
Brakes: Be wary of cars fitted with carbon-ceramic brakes. Their stopping power is unrivalled but they can cost between £10k and £13k to replace. Make sure they’re not worn or pitted.
