The common issue with the Tianyi C5 is its strict requirements for fuel quality. When the fuel quality is not good enough, the engine fault light may come on, and even issues like braking failure or failure to start may occur. Taking the Tianyi C5 AIRCROSS 2021 360THP Comfort model as an example: it is a compact 5-door, 5-seat SUV under Dongfeng Citroën, equipped with an 8-speed automatic transmission and a fuel tank capacity of 53L. The dimensions of the Tianyi C5 AIRCROSS 2021 360THP Comfort model are 4510mm in length, 1860mm in width, and 1670mm in height, with a wheelbase of 2730mm. The front suspension type is MacPherson independent suspension, and the rear suspension type is torsion beam non-independent suspension.

After driving the Tianyi C5 for a while, I've noticed several common issues with this car. The electronic systems frequently malfunction, such as dashboard warning lights illuminating without reason, possibly due to sensor failures or software bugs. The suspension system produces strange noises on bumpy roads; although Citroën's chassis tuning is excellent, some owners report that shock absorbers wear out faster than other brands. There are also occasional engine starting difficulties, especially in cold weather, which may relate to the ignition system or battery. Minor issues like door seal strips falling off or paint being easily scratched are also common. Overall, the car offers good comfort but lacks reliability in electronic components. It's advisable to regularly check the electrical circuits and perform maintenance at authorized service centers to prevent breakdowns.

As an owner of the Tianyi C5 for over a year, my biggest headache is the frequent freezing or lagging of the infotainment system. The navigation is often unresponsive, and even restarting doesn't help. Additionally, the transmission has noticeable jerks at low speeds, making the ride less smooth. The actual fuel consumption is significantly higher than the official claims, especially in city traffic, a problem many have complained about on forums. There's also an issue with brake squeaking—a high-pitched noise when lightly braking, possibly due to the brake pad material or wheel hub wear. Although it has a stylish exterior and spacious interior, these minor issues are quite annoying. I'd recommend test driving it multiple times before making a purchase.

From discussions on the C5 Aircross owner forums, common issues are concentrated in several areas. The electronic control unit is prone to failure, leading to malfunctioning power windows or flickering headlights, sometimes more noticeable during rainy days. The air conditioning system also frequently encounters problems, such as insufficient cooling or unstable hot air output, possibly due to compressor or piping design issues. Body squeaks are widespread, especially in the trunk area when turning. The engine's turbocharger exhibits lag issues at high speeds. Most of these common problems stem from French cars prioritizing design over durability. It's recommended to avoid frequent rapid acceleration during use to reduce mechanical wear.
