Why does the engine light keep coming on in my 2017 Kia Pegas automatic? After resetting, it lights up again after driving for a while. I've already replaced the oxygen sensor, but the problem remains.

Has anyone modified the LED headlights on a Kia Pegas? I'm thinking of replacing them because the halogen lights don't seem bright enough.

My 2021 Kia Pegas has a problem when I start driving on the highway—the tire pressure warning light comes on. But when I press the reset, it goes off. This happens every time I drive on the highway. Do any fellow drivers have the same issue?

Which type of LED light is better for the Kia Pegas, and which brand? I've tried several LEDs but none seem to provide a good result.

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?

The check engine light on my Nissan Sunny came on, showing fault code P0705-00, which indicates an issue with the transmission range sensor A. The car suddenly jerked, and then the gear indicator on the dashboard disappeared. After turning off the engine and restarting, the gear indicator reappeared, but after a while, the check engine light came on again. I went to a repair shop to clear the fault code, and it seemed fine while driving, but the issue occurred again after some time. This has happened several times. Could it be a problem with the right tail light base?

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.

How did you deal with the issue of the water temperature sensor malfunctioning and the temperature light constantly flashing? I replaced the temperature sensor, but it started flashing again after two months. Did you replace the thermostat assembly? 2017 model.

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?

Does a transmission remain durable after being repaired once? If it breaks again, how long did it take before you had to repair it again? [facepalm]
