I left my McLaren 540C parked for three months, and now the battery is dead. I've replaced the battery, and it can start, but the RPM is stuck at 1500, and all the brake lights are on. What could be the issue?

The original battery in your Haima S5 from 2016, manual transmission, has been in use for six years. After being parked for half a month, you jump-started it with a power bank and have been driving it 50 kilometers daily for a week, but it still remains in a discharged state. If the car can't start after being off for more than an hour, it might be time to replace the battery.

I feel like the brakes on the McLaren GT are really stiff. Is it possible to modify them later to make them softer? [Facepalm] After being stuck in traffic for half an hour, my right leg is sore. Also, how do you judge the distance on both sides of such a wide car? Every time I drive on narrow roads, I'm terrified of scratching it...

When braking to a low speed, there's a metallic noise. Does anyone know what's going on??? The brake pads were just replaced two or three months ago.

I got the RDX Premium 2WD on June 16, 2022. After parking it in the garage for 45 days while I was on a business trip, the battery was dead when I returned. The RDX's battery is really frustrating!

Hey car enthusiasts, does your Eclipse Cross rev to 1500 RPM when in Park?

I've heard that HiPhi only has three months left for a revival period. Does anyone have any insights? Although HiPhi cars are average (or rather bad) and the pricing is quite ordinary, the design is really cool! [laughing]

What should I do if my ES300h's battery is dead after being parked for half a month?

I've had my 2021 Jeep Compass for three years now. Last year, it was parked for half a month during the New Year, and the battery died, so I replaced it. In March this year, it was parked for over 10 days, and the battery was dead again. I replaced it with a new battery, and in May this year, after being parked for 9 days, the battery died again. What's going on?

The car is over three years old, and recently the key isn't working well. Could it be that the battery is dead?
