I often see mentions of Volvo's "12V battery severe charging fault, stop and repair immediately" warning. I would like to ask, if jump-starting is successful, does it not affect driving, just like a regular fuel car?

Is the maintenance cost for the 720s high? I've been looking into it for several days and I'm really tempted. Planning to buy one next year to drive to school for fun. But I've heard you guys say it has a lot of small issues. I don't plan to drive it often, so what's the approximate monthly maintenance cost? My family is kind of like "only pay for the purchase, not for the upkeep" [crying]. At the same time, I also need to maintain another four-seater car (not exceeding 500,000).

It seems like your car's brake pedal is hard to press in the morning when starting the engine, but it becomes lighter after the engine is on. This issue didn't exist before, and you're wondering if it's due to a vacuum pump leak. The dealership mentioned it doesn't affect driving. What should you do?

MG GS, with over 60,000 km, recently having trouble starting the car. It requires several attempts to start. Once started, five or six warning lights come on, and when pressing the accelerator, the car doesn't move, can't go over 10 km/h. It often needs to be turned off or re-shifted. Sometimes while driving, pressing the accelerator doesn't speed up the car, but the engine sounds like it's in neutral. It also jerks when moving. Local repair shops are hesitant to fix it, and the 4S shop is too far away. I'm worried the car won't accelerate on the road, which could lead to an accident. Seeking help.

If you're looking for a car with low fuel consumption and reliable performance, you might want to consider models known for their fuel economy and durability. Brands like Toyota, Honda, and BYD are often praised for their efficiency and reliability. Think about what features are most important to you and maybe even test drive a few models to see which feels right.

I'm considering getting an H7 because I like the spacious back seat and the solid appearance. I often drive on highways, so I'm okay with the fuel consumption. I'm wondering about the fault rate. How often does it break down? I usually have a few long trips of about a thousand kilometers each year, and I'm worried about getting stranded. Thanks, everyone! (*°∀°)=3

I've had my car for four and a half years and it's only done 36,000 km. It's a 2019 model with the 4J11 engine. Recently, when I start it cold, the engine struggles a lot. The RPM doesn't go up immediately, and the needle wobbles between 500 and 1000 for a few seconds, making it feel like it's about to stall. Then the RPM suddenly jumps to 2000-3000 before settling back to normal idle after a few seconds. There are no warning lights, and once it's running, everything seems normal. I've cleaned the carbon buildup and throttle, and checked the intake for leaks, but the issue persists. I'm not sure what to check next. What should I look into?

Here’s the situation: I just replaced the battery, but it's dead again. After starting the car, after a while, it reports a battery charging fault. Then the ABS and airbag lights also come on. When idling in place, after a while, the car will automatically shut off. When driving, it feels like it doesn't shift gears automatically, and I can't switch to manual mode either. Vehicle: Peugeot 207 1.6 Automatic. The battery wasn't great initially, and I didn't pay much attention to it, usually jump-starting the car. A few days ago, I replaced the battery. First, during driving, it started showing a battery charging fault. After a while, the ABS light came on, then the airbag light lit up as well. It's like a parade of warning lights. Now I'm wondering if it's worth repairing. What could be the issues?

I just went out for a drive, and it seems like there's a problem on the way back. Is there anyone who knows about cars that can listen and tell if it's an engine issue? It's the holiday season, how should I fix it? (Mainly worried about further driving damaging the engine.) The specific situation is that on the way back, there was a noise indicating a fault, but no warning light came on. Then during two turns, the steering suddenly locked and the car stalled. Since I wasn't far from home, I drove a bit more and parked at home.

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?

Is the Nissan X-Trail EP using a direct or indirect TPMS? If it's direct, after inflating the tires, it doesn't update the tire pressure immediately; it only shows the new pressure data after driving for a while, which seems a bit like the characteristics of ABS estimation. If it's indirect, it can still independently display the pressure of each tire, and the manual also mentions that the tire pressure display might be affected by wireless interference, which sounds more like the working principle of in-tire pressure sensors. So, I'm not quite sure why this TPMS needs to activate at speeds above 25 km/h.
