What owners say
650S
Overall
Sentiment is mixed, with a clear divide between the driving experience and ownership experience. The vehicle is widely praised by owners and enthusiasts for its exceptional performance, engaging driving dynamics, and significant technological advancements over its predecessor, the MP4-12C. It is described as a "peak" model in the brand's evolution, offering a carbon monocoque chassis, potent twin-turbo V8 engine, and involving handling that makes it feel "glued to the road." However, this positive perception is heavily tempered by recurrent and severe criticism regarding long-term reliability, build quality, and the manufacturer's customer service.
Best version to buy
Insufficient owner data available to declare a consensus "best" version (e.g., Coupe vs. Spider, standard vs. optional packages).
Known issues
- ⚠General reliability and build quality concerns: encompassing electronic gremlins, component failures, and fit-and-finish issues, noted as a brand-wide problem. Frequency: very frequent.
- ⚠Hydraulic system accumulator failure: a consumable part that fails every 3-4 years, causing PCC errors and preventing suspension mode changes. Frequency: recurrent.
- ⚠IRIS infotainment touchscreen failure: screen becomes unresponsive, no aftermarket alternative, costly OEM replacement ($2,000-$4,000). Frequency: recurrent.

However, there is a strong, recurrent recommendation to seek out later-production examples (e.g., 2013-2014) and cars with higher annual mileage (2,000-5,000 miles per year) as they are believed to have had early gremlins addressed under warranty and suffer fewer issues from sitting idle.
Known issues
- ⚠Electronic system malfunctions: Infotainment (IRIS) screen touch failures, system freezes requiring reboots, climate control LCD screen failures, "key not found" errors, various warning lights. Frequency: very frequent.
- ⚠Hydraulic system accumulator failure: PCC (Pneumatic Control Circuit) errors, suspension mode change failures; consumable items needing replacement every 2-4 years at a cost of approximately $1,400-$5,000. Frequency: very frequent.
- ⚠Transmission concerns: Reports of complete transmission failures requiring replacement (costing ~$30,000), though some owner discussions suggest this reputation may be overstated and linked to warranty repair practices rather than inherent…
