Oil light and battery light on.
My car has 160000 miles.
My car has an automatic transmission.
The oil pressure light will usually come on when a few things could be happening. Either the motor is in fact low on oil, the oil pump could be failing or the oil pressure sending unit is not working properly and may be producing a faulty reading. If the engine is in fact low on oil, you may notice the temperature gauge reading above normal temperatures as a result of the lack of sufficient oil in the motor. I would recommend checking the actual oil level in the motor by using the dipstick. Be sure the oil level reaches the "full" mark. If this registers as "full" then you likely have a faulty oil pressure sending unit. Many vehicles also have a safety feature built into the vehicle’s computer system which will shut the engine down completely or trigger a “safe mode” of some kind which will drastically limit the vehicle’s engine power to avoid further engine damage until the oil pressure problem is corrected.
Your battery light will generally come on when there is a fault detected with your charging system or in the event you have a weak battery. As you may know, the alternator is responsible for charging the battery while the engine runs by generating amperage and recharging the battery while the engine turns the alternator. The voltage regulator is a unit that regulates the charging of the battery by the alternator and maintaining a certain amperage while the engine runs. When the alternator is not working properly, this may result in the battery quickly losing charge and the car losing all power as you have described. You may also notice a whining sound as a result of the bearings inside the alternator begin to fail. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
How to Identify and Fix Common car Problems ?

If the cranking of the engine is sluggish, like your vehicle is harder to start on cold mornings, it starts inconsistently, or there`s no sound and interior lights when you try to start, suspect a failing battery, a loose or corroded connection or electrical draw.
If you find that the level is good, but you hear loud grinding or ticking noises coming from the engine, this could mean that your oil pump isn`t working, and you should not start the engine back up until it`s fixed.

As you may know, these lights are designed to come on at specific mileage intervals that are preset by the factory. When your mileage exceeds a certain amount relative to the last oil change, this will trigger the lights to come on. Typically this will include the oil light and the check engine light as there are also other basic service items that are checked during oil changes. I would recommend obtaining an owner’s manual for your car if you do not already have one. This will usually indicate the specific service intervals and recommended maintenance items for your vehicle at the various mileage intervals.
The tire pressure monitor will also come on when the air pressure in the tires has reached a specific threshold relative to the tire design specification. Tire pressure is also impacted by the outside air temperature. For every 10° drop in air temperature outside your tires will lose about 1% in PSI or inflation. As you may know, as the temperature of the air changes the density of the air changes as well causing the tire pressure to be impacted by this. When this happens, the sensors in the wheels will detect this change in tire pressure and cause the tire pressure light to come on. Aside from replacing faulty tire pressure sensors, another way to help prevent this type of fluctuation in tire pressure is by the use of Nitrogen in your tires rather than regular air. As you may know, air is approximately 78% Nitrogen, 21% Oxygen and the rest is water vapor and some other small concentrations of gases. Nitrogen is much less likely to migrate through tire rubber than oxygen. This will maintain your tire pressure much more consistently during large temperature fluctuations.
If you’d like, a YourMechanic certified mechanic can come to your home or place of business to inspect the vehicle and perform an oil pressure light is on inspection to diagnose the vehicle and suggest potential repairs.
I suggest you have a certified technician, such as one from YourMechanic, come to your location to determine why the Battery Light is on and suggest the necessary repairs.
If you want to have this electrical issue checked out, consider having a certified mechanic, such as one from YourMechanic, come to your home or office to inspect the electrical system and suggest any necessary repairs.
