Peugeot 308 (T7) Problems by Year

The Peugeot 308 (T7, 2007–2013) marked a notable improvement over its predecessor in terms of build quality and design, establishing itself as a popular family hatch and estate on UK roads. However, prospective buyers must navigate a complex reliability landscape, as this model generation is known for specific mechanical and electrical challenges. Success in ownership for this generation is heavily dependent on identifying which powertrain is fitted and ensuring a meticulous maintenance history. The most significant mechanical concerns are centered on the 1.6-litre petrol engines developed in partnership with BMW, particularly the turbocharged THP variant. These engines are known for issues with timing chain stretch—often manifesting as a noticeable "death rattle" on startup—and significant carbon buildup on the intake valves, which can lead to rough idling and power loss. Conversely, the 2.0-litre HDi diesel is widely considered the most reliable engine of the range, proving robust over high mileages, while the smaller 1.6 HDi requires regular oil changes to protect the turbocharger from carbon-related failure. Electrical gremlins are also a recurring theme, with owners frequently reporting phantom warning lights, often traced to faulty brake switches or sensors, and potential issues with window regulators. Furthermore, water ingress in the spare wheel well or rear footwells is a known weakness, often linked to poorly sealed rear light units or blocked scuttle drains. Given the age of these vehicles, thorough inspection of the cooling system, including the water pump and thermostat housing, is strongly advised. While the 308 T7 offers a comfortable and stylish package, it is not a "fit-and-forget" vehicle, and diligent preventative maintenance is the key to longevity.
