Warning - this recall is a scam to drive dealership service revenue fees since new car sales have significantly slowed. The service department will produce a laundry list of issues, like ECM not working that the customer must pay for before they ever do the recall. If you pay this and let them get inside the engine, watch out. You will be held hostage for massive other internal engine repairs that will be "mandatory" for Nissan to put your car back together.

Never heard of this. I am curious where you are and how you got this fake notice? What model and year Nissan are we talking about?

The notice is real, came from the MVD during an emissions test. The fix used to be taking the engine apart and replacing the piston rings. The fix is now loading a program on the ECM that will put the car in "limp home mode" - limit the RPM to 1800 if the sensor reads a drop in oil pressure- sounds real safe for freeway driving.... If the EMC won't take the update, they want the consumer to pay for a new ECM - over $1,000

What year Sentras does this affect. All I can find is this
06V223000
Recall Date
06/21/2006
Component
ENGINE AND ENGINE COOLING
Summary
CERTAIN PASSENGER VEHICLES EQUIPPED WITH 2.5L ENGINES MAY EXPERIENCE EXCESSIVE ENGINE OIL CONSUMPTION AS A RESULT OF IMPROPER PERFORMANCE OF THE PISTON RINGS.
Consequence
IF THE OIL IS NOT MAINTAINED AT LEAST AT THE MINIMUM LEVEL, ENGINE DAMAGE CAN OCCUR AND IN EXTREME CASES RESULT IN AN ENGINE FIRE.
What Owners Should Do
DEALERS WILL REPROGRAM THE ELECTRONIC CONTROL MODULE (ECM OR ENGINE COMPUTER). YOUR VEHICLE WILL ALSO BE INSPECTED TO DETERMINE IF IT HAS BEEN CONSUMING ENGINE OIL AT A HIGHER THAN NORMAL RATE. IN A SMALL PERCENTAGE OF VEHICLES, ENGINE REPLACEMENT WILL BE NEEDED. ON JUNE 9, 2006, NISSAN NOTIFIED OWNERS OF THE POSSIBILITY OF EXCESSIVE OIL CONSUMPTION AND THE IMPORTANCE OF MAINTAINING THE OIL AT A PROPER LEVEL. FOLLOW-UP LETTER TO OWNERS ADVISING THEM OF THE STATUS OF THE RECALL WAS SENT DURING AUGUST 2006. FOLLOWUP LETTER TO OWNERS WAS SENT ON NOVEMBER 15, 2006. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

This is from 2006 we are now 2019.

Yeah, I remember that recall. It actually started before I left Nissan in late 2003. The QR25DE engine made its debut in the 2002 Altima and some of the Sentras. Not long afterwards, they were having issues with oil burning engines. The cause was said to be due to the ECM programming causing the engine to run in such a way that it caused the catalyst substrate in the upstream catalytic converter (which is integral with the exhaust manifold) to break up. This engine uses the variable valve timing to perform EGR by cracking open the exhaust valve during the intake stroke. When this occurred, small bits of substrate could get sucked past the exhaust valve, into the combustion chamber, where it would score the cylinder walls. The longer it went on, it would cause reduced sealing between the cylinder walls and piston rings, resulting in low compression and an oil burning engine.
When the recall came out, there were a number of things done. More heat shields were added to the upstream converter, the ECM was reprogrammed with updated software and a compression test was performed on the engine. If the compression test failed, then the engine had to be repaired under warranty. At first they were replacing the piston rings and honing the cylinder walls, but then it got changed to changing the engine long block w/ rotating assembly and finally they went to replacing the entire long block assembly.
This recall was terminated a long time ago, to my knowledge. Anything under a recall is at no cost to the consumer. After the warranty is terminated, which is based on a number of factors, the recall procedure could still be done but it would be done as customer pay. I believe the recall was on 2002-2004 models with the QR25DE engine.
