    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

So after my car warms up, everything sounds fine and runs well. When I come to a complete stop, my red oil light comes on and goes off when I drive. I decided to get a code reader to see what is causing the light to come on. The code reader gave me p0116 which has to do with the engine coolant temperature circuit/range. Anyone else experience this??

Oil pressure is not monitored by the OBDII system. There will be no codes for it. It's the same oil light that cars had many years before computers.
There is a switch on the engine that is opened by oil pressure. The light tells you that the engine has little to no oil pressure. This can be because the oil pump is failing, the oil pickup is clogged, the engine bearings are worn out, or the pressure switch itself is failing. Fortunately, it seems that the switch failing is the most common problem.
 
I'd bring it in to get it checked. Joe hit all of the possible problem areas. You'll need to get the oil drained anyway, so have them drop the pan too.
 
Had the same issue with oil pressure light turning on when car was stopped. Took it to dealer and had the oil pressure sensor replaced under extended warranty (not covered by 10y/100k powertrain). I believe they billed parts/labor for around ~$800. It's not a fun job as the air intake / manifold have to come off, sensor is recessed in the top of the block and difficult to access:


The new sensor worked for a few days, but the light started coming off and on again, eventually just staying on and kicking on the check engine light too (which is not what you want to see with an oil pressure light lol). The code PO522 was for the OPS sending too low of voltage. Dealership managed to get me in and take the engine apart again, much to their confusion the new pressure sensor was faulty, apparently they've replaced a lot of them as it's a common issue, but first time they had a dud.

Canadian or American dollars??

Dealership says its the pump. 3500 Canadian for 15 man hours to fix. Goes in this monday

Hopefully, it did not starve the engine of oil long enough to do damage to the rest of the engine...

Yes!!! I am experiencing it with my 2016 Genesis.

Damn. You got to remove the upper and lower intake manifolds just to change an oil pressure sensor. I agree with the tech in the video that is too much effort for an oil pressure sensor. Most are easily accessible on an engine.

Lexus V8's require you to take the better part of the top of the engine to get at the starter (buried in the V). Over $1000 to do that.

That do sucks for a Lexus owner, but I am referring to the oil pressure sensor that the thread is about. Oil pressure sensors are usually fairly easy to get to without breaking an engine down to the valley. Some models may require the plastic upper intake manifold be removed, but not the lower intake manifold.

Plus, Lexus original starters usually last about 200k- 300k miles. So most original owners will never ever change one out. Genesis 3.8 owners are replacing these oil sensors with less than 100k miles, hopefully under warranty. The oil sensor repair can get expensive if paying out-of-pocket due to the labor cost of just breaking the top of engine down for a $40 sensor.

The more recent LS460's aren't built as well as their predecessors. I'm reading them going out between 60,000 and 80,000.
My statement was made in regards to poor placement of components on cars. If Hyundai/Genesis can do it, anyone can. Don't get me started on BMW. They make our cars look ultra reliable.

I do not know where you got your information about the Lexus 460 starter reliability, but from my research the 2013 and newer models are fairly reliable pass the 100k mile mark. The ABS units seem to the biggest issue on those cars since it cost nearly $5000 to replace; hence why I decided not to buy a used LS460 years ago. However, every car has it issues that makes owning them a pain; Lexus is no different. Replacing the starter on a Lexus V8 is nearly the same process as changing an oil pressure sensor on the Genesis. I would never ever consider buying a used BMW due to amount of work one of those will need by 100k miles.

It still does not change the fact that the Genesis 3.8 models has a defective oil pressure sensor located in the very hard to access valley of the engine that is a very common issue on these cars out of warranty. Not good.
 
As for years of use, I wouldn't anticipate an 8 to 9 year old car to have many issues. Lexus has had its issues. Including the melting dashboard and door cards. ABS modules. Front rotors and brakes (some going out as soon as 2,000mi). Starters. Air suspension.

I am truly thankful for the Genesis, as they kept the car as simple as they could. A very reserved interior, channeling the best of Lexus and Mercedes Benz.

Lexus models are not perfect and also have their fair share of problems for sure like any luxury car or any car in general.

Genesis models are nice cars hence why I own one, but Hyundai did not make changing the oil sensor simple as discussed.

Lets hope their latest generation of engines are better designed.

Yes this just started on my car and I have a 2019. Genesis g80
 
I’m having the same issue, my oil light is off and on. How much does it cost to replace the switch
