I drove for about an hour at night, and the battery warning light came on. Then I stopped driving. The next day, when I drove again, the warning light was off. Can you tell me what's going on and if it's serious? Thanks.

I bought a second-hand 2014 Kia Sportage, and the exhaust smells really bad. I hadn't driven it on the highway before, but a few days ago I did, and the engine warning light came on. The check indicated an issue with the oxygen sensor. After replacing it, the error code was cleared, but a few days later it came on again. It seems fine when not driving on the highway, but as soon as I do, the light comes on and stays on. Can any experts advise on how to fix this issue?

It snowed last night and when I drove to work in the morning, the brakes made a crunching sound!

While driving normally and making a U-turn, the gears suddenly started jumping. The engine didn't stall, but there was no power. The engine malfunction light came on, and the ECO indicator disappeared. After restarting, the car drove normally again, but the malfunction light remained on.

I just got a 2011 Mazda 5 a couple of days ago. After only two days, the check engine light came on with the code P2177. Can anyone help explain this?

The car is a 2015 model and has run 99,000 kilometers. The warning light turned on, and you replaced 4 ignition coils and 4 spark plugs. After some time, the light came on again, and the engine shakes when starting, but it's still drivable, though the light remains on. What's causing this issue?

The dashboard reported low transmission performance, and then the car wouldn't accelerate. After restarting, the warning light went off and it drove normally. What could be the reason? (The onboard computer cleared the fault light, but it came back on before I got home.)

After cleaning the throttle body yourself, the engine warning light came on. It doesn't affect driving, but how can you resolve this?

After the light came on, I drove 20 kilometers and then refueled 65 liters. I'm starting to doubt if my fuel tank is actually 80 liters.

The car was fine when I parked it, but the next day when I started it, the engine fault yellow light came on. The car runs fine, but the yellow light stays on. It's been almost two years; does anyone know the reason? 😢
