The tire loses air slowly, needing to refill every three to four days, but the tire isn't damaged. What could be the reason?

If I leave my car unused for three days, the battery dies. How long can your cars sit without losing charge? I'm thinking of getting an emergency jump starter. Could you recommend a good brand? Thanks!

The air conditioning in the 2011 Kia Sportage has cool air but isn't cooling effectively. What could be the reason?

When the air conditioning blows cold air for a while and then switches to hot air, and after being turned off for a bit, it works again before reverting to hot air, it's puzzling. Interestingly, this issue doesn't occur on rainy days or when the weather isn't too hot. What could be the cause of this situation?

Has anyone experienced starting issues with their car? This problem has been going on for over a year. I've replaced the battery, cleaned the fuel lines, changed the spark plugs, and replaced the fuel pump, but still can't find the issue. The dealership is also at a loss. Every time I try to start the car, it takes three attempts to get it running. It feels like the fuel isn't reaching the engine when starting. I'm now afraid to drive, because if the engine stalls, it'll take three attempts to start it again. 😢😢😢 Does anyone know the reason?

Have you ever experienced driving 10 kilometers every day and suddenly noticing a time difference of exactly one hour, without any minute discrepancy? What could be the reason for this?

Why does the 2022 GA6 luxury version always prompt that the battery is low every three to four days?

I accidentally hit the curb with my left rear wheel and the tire got damaged. During the four-wheel alignment, they said it couldn't be fully adjusted. If the tire is damaged, does it really require changing the shock absorber? Is it really that serious?

I've got a 2009 Peugeot 307, and the air conditioning isn't cooling very well. I had it recharged with refrigerant, but it still doesn't get cold enough, especially on hot days. Any idea what might be wrong?

Hey everyone, the AC isn't blowing any air, and there's no air coming out on internal circulation, only natural airflow. Have you encountered this before? Is it the blower that's broken? I saw online that there could be many reasons. Is it necessary to replace the blower with an original one?

Why do my Ariya tires need to be inflated every week? All four tires are losing air. I inflated them to 270 kPa, but after a week, they're only at 250-260 kPa.
