The Start-Stop system of the Peugeot 5008 frequently exhibits malfunctions, which can manifest themselves in various symptoms. The function does not start even though all conditions are met, or the engine switches off and on again irregularly. These problems occur particularly frequently with the 1.2 PureTech and 1.6 THP engines, often accompanied by error messages in the display. The reliability of the system is significantly impaired if there are defective sensors or software errors. Breakdowns due to complete system failure are not uncommon, especially in models from 2011 and newer variants.
A systematic check is essential for the Start-Stop system to function properly. The sensitive Peugeot 5008 battery sensors require regular calibration and checking of the voltage values, as even the smallest deviations can lead to malfunctions. In addition, the engine control units should be checked for the latest software updates and reprogrammed if necessary. The service life of the system can be significantly extended by regularly maintaining the battery and checking all electrical connections.
The head-up display of the Peugeot 5008 develops mechanical defects, which become noticeable through incomplete or complete failure of the exit process. The display gets stuck in the dashboard or only moves jerkily and does not reach the intended position. These faults occur more frequently in the GT versions and higher equipment lines, as the system is installed here as standard. The symptoms often worsen in extreme temperatures, both in winter and summer. The motor and gearbox of the extension mechanism show signs of wear, which can lead to permanent functional failure.
Professional maintenance is required to check the complex mechanical components. The precise Peugeot 5008 Head-Up Display mechanisms require special lubrication and regular cleaning of the guide rails every 30,000 km. At the first sign of problems, the electric motors and gears of the extension system should be checked. Preventive treatment with suitable lubricants and the timely replacement of worn components prevent costly complete failures of the entire display system.
The electric tailgate of the Peugeot 5008 does not open or reacts unreliably to attempts to operate it via the remote control or interior button. The problem manifests itself in two typical "waves": initially at low mileages of around 15,000 km due to software errors and later at 80,000-100,000 km due to mechanical wear. The automatic tailgate does not switch properly, which can lead to safety problems when loading and unloading. The diesel versions 2.0 HDI and 1.6 HDI also have problems with the power supply. The key is not recognized when the tailgate is opened using the remote control, which indicates defective sensors.
Regular maintenance is essential for the longevity of the electric tailgate. The complex Peugeot 5008 tailgate actuators require a check of the mechanical components and lubrication of the joints every 20,000 km. The control units should be read for error codes and reprogrammed if necessary. Particular attention should be paid to the microswitches and sensors responsible for position detection, as their failure can lead to complete system failure.

The air conditioning system of the Peugeot 5008 does not cool sufficiently or continuously loses power, which is particularly noticeable in the summer months. These complaints occur more frequently with the 2.0 HDI 150 and 1.5 BlueHDI 130 engines, often accompanied by unusual noises from the engine compartment. The system is not working properly if there are refrigerant leaks or defective compressors. The heating does not work properly if the heat exchanger is also affected. Symptoms such as misted-up windows or musty odors from the air vents indicate other problems in the air conditioning system. Reliability is severely impaired, especially in vehicles with high mileages over 60,000 km.
A professional inspection is required to check the various components of the air conditioning system. The sensitive Peugeot 5008 air conditioning compressors require regular checks of the refrigerant level and the seals every 15,000 km. The cabin filter should be changed annually to ensure optimum air quality. Professional maintenance with air conditioning cleaning and disinfection every 30,000 km prevents bacterial contamination and maintains the full cooling capacity of the system.
The timing belt and timing chain of the Peugeot 5008 show different problem patterns depending on the engine variant. In the 1.6 THP and THP 165 engines, timing chain wear occurs from 60,000 km, recognizable by rattling noises during cold starts. The 3-cylinder engines such as the 1.2 PureTech often develop problems with the timing chain between 80,000-120,000 km. The engine does not start or runs unevenly if the timing chain is skipped. In the 1.6 HDI and 2.0 HDI diesel variants, timing belt ruptures are possible after 100,000-150,000 km, although the replacement intervals provide for longer running times. The service life is significantly reduced by frequent short journeys and irregular maintenance.
A systematic check is essential to avoid costly engine damage. The critical Peugeot 5008 timing chains require regular checks of tension and wear condition every 20,000 km, especially on the direct injection gasoline engines. An immediate inspection should be carried out at the first sign of noise or uneven engine running. The preventive replacement of timing belts and timing chains in accordance with the manufacturer's specifications prevents serious consequential damage to valves and pistons.
The heating in the Peugeot 5008 does not work or only works inadequately, which is noticeable through cold air from the air vents or uneven temperature distribution in the interior. At the same time, there are often problems with the radio, which cannot be switched on or fails while driving. These complaints are often linked, as both systems are supplied via common control units and fuses. In the 1.6 petrol engines and the newer 2019 models, electronic faults in the climate control system are particularly common. The radio does not work if the heating control fails at the same time, which indicates defective control units or wiring harness problems. The symptoms often worsen in damp conditions or extreme temperatures.
Professional maintenance is required to check the electrical connections and control units. The complex Peugeot 5008 climate control systems require regular diagnosis of the electronic components and checking of the cable connections every 25,000 km. Software updates for the radio and climate control system should be installed promptly to eliminate known compatibility problems. Systematic fault diagnosis with professional diagnostic equipment identifies defective modules and enables targeted replacement of the affected components.
