I've had this car for over three months, and after driving more than 4,000 kilometers, it feels really sluggish below 3000 RPM, like it's lacking power. Can any experts help me out? Thanks. It's a 2.7.

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?

When driving the 2014 Foton Tunland 2.8S 4WD, there is a noticeable humming vibration in the cabin when the alternator speed is below 1600 RPM. However, once the engine speed reaches 2000 RPM, the humming sound disappears. Could any experts advise on what might be causing this issue?

Peugeot 206, 1.6L, automatic/manual transmission, 2006 model. The acceleration is very slow, and when you give it more gas, the RPM goes up, but the speed doesn't catch up. What's going on? Can any experts help explain this? Thanks!

When I was driving my Toyota Yizhi with the CVT in D gear and stepped on the gas to 4000 RPM for overtaking, I suddenly felt a lack of power and then it sped up. They say this is the steel belt slipping, and driving like this can damage the transmission. I'm frustrated. What happens when the steel belt slips? Can any experts explain this?

Brother, can I buy it with a monthly income of 3000? I feel like 3000 is more than I could ever spend in my lifetime.

The temperature is around minus three degrees, and suddenly today the gear shifting is very slow. It used to shift at around 2000 RPM, but today it goes up to 3000 RPM. The engine is making a humming noise. 😵‍💫 Do any other T-Cross owners experience this situation?

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?

As a new driver, I've only driven the 2019 2.0 model, and I find the acceleration quite sluggish. When I press the gas pedal deeply, the engine needs to reach around 1800-2000 RPM to speed up a bit, and the engine noise is quite loud. Is this normal for a naturally aspirated engine with a CVT? I tried using the DS mode, which seems to provide what I consider normal acceleration, but I noticed the RPM goes up to four or five thousand. My friend's 1.5T Geely doesn't make much noise and feels more powerful.

The front windows of the Jetour X70 cannot be opened, and the horn alarms when the car is locked with the remote. When the unlock button on the remote is pressed and held, only the rear windows open, while the front windows do not respond. I had this issue repaired at the 4S shop before, and they said it was related to the fuse. However, the problem has occurred again just two to three months after the repair.

I've had the Nissan X-Trail Hybrid for just half a month and took it on a long trip, about 3000 kilometers. Everything else is fine, but once the dual-zone climate control is turned on, it can't be turned off. Also, when the engine starts, there's a loud noise like an electric drill. Do any other owners have the same issues?
