When the speed is around 43, the headlights noticeably get brighter than before. What feature is this, and which lights are getting brighter?

I upgraded to high-end headlights on my Pathfinder, and they flicker when I use the start-stop feature. Is there a solution for this?

Why does the right front wheel of my 2019 GA6 get about ten degrees hotter than the other three wheels after driving for a while? When I touch the hub, the temperature difference is quite noticeable.

What could be the reason for the headlights and brake lights turning on by themselves at night?

Have you noticed water droplets inside some car headlights? What's going on with that?

When I start the car, the idle speed is around 2000 RPM, but after a while, it drops to 1500 RPM. It takes quite a long time to go down to around 1000 RPM. Does anyone know what's going on?

Hello everyone, does anyone know how to modify the daytime running lights to stay on all the time? Originally, the DRLs are on during the day when the headlights are off, but they turn off when the headlights are on at night. I want them to stay on regardless of whether the headlights are on or off.

When slowly accelerating at low speeds, the V60 B4 2024 model experiences noticeable jerking and dragging.

When lightly pressing the accelerator at low speeds, there's a slight jerk, and when the RPM drops below around 1100, there's a dragging feeling. What could be the problem?

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?

Can the new Jetta's headlight cover, which is higher than the grille, be adjusted to be level? Any car enthusiasts who know about this, please give some guidance.
