Your best bet , have it checked for DTC'S - diagnostic trouble codes first ! Electronic control modules involved ! Can't check with a OBD 2 code reader , need advanced scan tool . No codes , check B+ voltage and ground to the module .
Power Seat Inoperative (With Memory A45)
Memory Seat Feature Inoperative
Circuit/System Description
Battery voltage is supplied at all times to the memory seat module (MSM) from the MDL-MEM 10A fuse located in the rear fuse block. This voltage is used by the MSM for logic power and to supply battery reference voltage to the seat and lumbar adjuster switches. Battery positive voltage is also supplied at all times to the MSM from the PWR SEAT 25A circuit breaker. This voltage is connected to a power rail internal to the MSM and is used to drive the power seat motors, lumbar motors, and seat heater elements on vehicles equipped with heated seats. Each seat and lumbar adjuster motor is controlled by the MSM through 2 motor control circuits. The MSM connects all motor control circuits on the power rail to a common reference point whenever they are not in operation. This reference point is biased to approximately 2.5 volts. The MSM checks to see if the reference voltage is shorted to ground or battery before enabling any of the seat or lumbar motors.

Circuit/System Description
Reference voltage is supplied to the memory switch from the driver door module (DDM). When a memory switch is pressed, reference voltage is applied through the switch contacts, a series of resistors and thorough the memory switch signal circuit to the DDM. The door module then sends a serial data message to the memory seat module (MSM) indicating the memory recall request. The MSM then commands the appropriate seat motors to move to the pre-recorded seat positions stored in memory in response to the switch input.

Probably a blown fuse, this is how to replace it.

It seems to me you may need to replace the low pressure sensor located inside the rim.

You must remove the coils that cover and go over the spark plugs.

There is no asstton* on the 2008 ES350 to switch off the traction control (( pain in the *** when it snows+slippery )).

From forums online, and I\'ve personally tested/used this...

Keep the hand brake on (( its near the left leg )) when u switch on the car... And in the next few seconds, hit and release the brake twice, then
keeping your leg on the brake pedal, release the hand brake, and put it on again (( twice, your right leg on the brake all this while )), and then when the hand brake is on, hit and release the brake twice...

You will need to do this only immediately after the car starts, and it needs to be done in under 30 seconds (( from forums, never needed more than 10 seconds to do the whole thing ))..

They do not recommend it cause apparently, the torque generated can cause the wheels to spin so much that it causes tires to burn out soon... Good luck!

I wonder if you dont have a bad switch. I had a similar problem on my car except that it was the heated seats that would not engage... the power seat buttons all worked just fine. I changed the switch and it fixed the problem...

Note: this was on a BMW not a Murano

I'm thinking of buying a 2008 ES 350 and have read the transmission flare discussions on different websites. I wouldn't want to venture a guess as to what the chance is of getting a new ES 350 with a flare problem: 0.1%, 1%, 10%, 50%? If the ES 350 has a flare problem, what is the chance of it being a severe problem vs. a minor nuisance: 0.01%, 1%, 10%, 90%? I've read about other problems afflicting the ES 350 such as engine knocks, interior rattling noises, and wind noise. I'm sure the ES 350 has some minor problems too but those are the major ones I can recall. The easy answer for the potential buyer is to cross off Lexus from the list. Why take the chance? The ES 350 was easily my #1 choice in terms of features and value. I was attracted to the Lexus brand because my impression was that Toyota and Honda generally make the highest-quality under-$40K cars in the world. What would make more sense than buying from Toyota's "luxury" division? Car magazine journalists regularly write about "legendary Lexus quality." That leads to a contradiction: Why does Toyota have such a stellar quality reputation even though it has had ongoing FWD transaxle problems since 1999? Why can't Toyota figure this out? Shouldn't Toyota thoroughly test pre-production models instead of making its customers responsible for quality assurance? Replaced transmissions, buybacks, amazing. It's hard to figure out the precise truth and a manufacturer is probably going to avoid transparency in this kind of situation, so I think I should move on to other makes and models. Any suggestions for FWD alternatives to the 2008 ES 350?
