Car experts, why is my front left radar giving false alarms? At first, I thought something was stuck on it. I got out and wiped it for a while, but it's still going off a lot, especially when waiting at traffic lights.

Hello everyone, I'd like to ask something. When I cold start my car, the idle speed is quite high and when I release the brake, the power is strong and it just surges forward. But after driving for a few minutes or waiting at a few traffic lights, it starts to lose power. When I release the brake, it moves very slowly, and it only gets a bit better if I press the accelerator. It's a 2007 model with an automatic transmission.

I can't charge my electric Lavida, thought it was a grounding issue (there's a grounding wire left by the developer in the electrical box), so I connected it to the ground as well, using two 60cm grounding rods and a 50cm grounding angle iron, but it still sometimes charges and sometimes doesn't. Even the portable charger doesn't work. It's driving me crazy. When I took it to the 4S dealership, it charged fine. They updated the car's system, but it still won't charge at home. I tried two neighbors' charging stations, but it still won't charge. What's going on? Has anyone experienced something similar? It's been over 3 years and 50,000 km.

Hello everyone, I have a question: My Mazda 6 had the engine light and oil light come on after shifting to neutral while waiting at a traffic light. The idle was normal, but there was no response when I pressed the gas pedal and shifted to drive. After restarting the car, everything went back to normal. I went to the dealership, but they couldn't find any error codes. Has anyone experienced something similar? How can I fix it?
