Problem with engine power and gear shifting in a Dacia Sandero

Hi, I have a 2016 Dacia Sandero with a gasoline engine and 4000 km on the odometer. I have experienced several problems with the car, including loss of engine power, difficulty starting the ignition, jerking during acceleration, clicking/knocking sounds from the engine, and the gearbox slipping or shifting irregularly. Over the past few months, the car has become increasingly uneven in rpm and more erratic when shifting (automatic). Engine vibrations are felt throughout the car, and sometimes it feels like the engine is losing power. When I start the car and drive away, it vibrates strongly, almost as if it's trying to stall, but since it's an automatic, it doesn't. Now I've also noticed that a loud warning signal sometimes sounds while driving, but no lights come on to indicate what the fault is. The only light that's on is the tire pressure light, which came on after a tire change, but I've checked that the pressure is correct. What could be causing these problems and how should I proceed to solve them?

Start by checking the battery and alternator to ensure they are functioning properly, as electrical issues can cause multiple symptoms like power loss and erratic shifting. Inspect the battery terminals for corrosion and ensure they are tightly connected. If the battery and alternator are in good condition, consider having the vehicle's computer scanned for error codes, even if no warning lights are on, as this can provide clues to underlying issues. Please update on your progress or if you have further questions.
