I signed the contract on November 3rd. There's a car available, and the certificate of conformity is ready, but as of today, the 28th, I still can't pick it up. They say it's because there's no release certificate, which is needed to take the car out of the warehouse. Is this normal? It's already been 28 working days.

Hello fellow car enthusiasts! I'm having an issue with my car and would like to seek your advice. The check engine light is on, and it's hard to start the car (it takes a while to start). Once it starts, the RPM is normal, but as soon as I shift gears, the RPM immediately jumps to over 1000, almost 2000. When I shift back to Park, the RPM slowly returns to normal. I've already replaced the throttle, and it worked fine for two days, but now the same problem is back. Has anyone else encountered this? What could be the issue?

On the day of the Mid-Autumn Festival, the reverse camera and 360 stopped working. I went to the 4S shop the next day for recalibration to fix it. Because the steering wheel was vibrating while driving on the highway, I did a wheel balancing and four-wheel alignment. Today, while driving on the highway, I noticed that the speed range at which the steering wheel vibrates has expanded, and now the seat also vibrates above 124 km/h. Can any expert provide some guidance?

I didn't drive for two days, and when I started the car today, I noticed the engine warning light was on. For the first ten minutes or so, pressing the accelerator only increased the RPM, and the speed stayed below 20. After driving for about ten minutes, when I pressed the accelerator, there was a humming noise, and the speed gradually picked up. However, the fuel consumption display kept changing even when the car was parked or just started and not moving (or maybe I hadn't noticed this before). Can anyone advise what's going on? Has anyone experienced this before?
