Greetings,

Im new here, just bought my 17 ES 350 @ 9K miles for $28k

Within 3 days of ownership and less than 100 miles, the car threw the P0335. Took it to Lexus of Riverside ( where I purchased it from) and they said due to vehicle sitting there for while, the battery voltage dropped and wasn't able to properly supply enough voltage to the sensors. Their remedy was to drive the vehicle more to allow battery to charge and problems will not arise again....? Thoughts...?

 

Well take it on Highway for couple mins.
And if it still shows next time...Just go to Dealer....Stair at them and demand a NEW BATTERY or Fix the problem.

 

yep, I agree..

 

Even though the car has low mileage the battery is 3 years old and on the downside of its life expectancy. As others have said I would take it on a longer drive and then have the dealer do another voltage check. Another low voltage reading and hopefully they give you a new battery.

 

Note that, if the car was sitting on the dealer's lot long enough for the battery to be completely discharged, it is likely that the battery has been permanently damaged. It may be the case that it can be charged now to a level that allows you to be able to start the car, but the battery's ability to hold a charge or to be able to provide its full original power may be significantly reduced. It would be a good idea to have someone other than the dealer do a check of the battery's current health. If there has been permanent damage to the battery, you should ask the dealer for a battery replacement.

 

>Their remedy was to drive the vehicle
WTF?? Why didn't they put it on a charger for a couple of hours and then do a battery check.

I'd tear the Service Writer a new one based on that shoddy customer relations. They deserve many Yelp negatives.

The dealership did the absolutely right thing. P0335 is highly unusual and most likely a glitch - possibly caused by undervoltage condition. The first step in fixing it is to reset the light and see if it ever comes back.

 

>reset the light and see if it ever comes back.

But he didn't say that they did that, only that he was supposed to: drive the vehicle more to allow battery to charge

I believe this implies the light was reset

 

So the dealer pretty much just cleared all the codes and called it a day. My thoughts are since the crankshaft sensor only works when the car is turned on, the alternator is the source providing 13-14V at all times to the sensor...

On day 2 of driving, so far for nothing. Oh and they said no to a new battery....

 

This sensor also needs to work during cranking - it tells the computer when to inject fuel and generate a spark.

 

Not an uncommon situation for a car that sits, or has poor battery terminal connections. In my friends shop it is common to see codes come in when a battery is low, no matter what make it is. He clears the codes, makes sure water level is good in non sealed batteries, checks terminals are clean and secure, and recommends to either drive the car awhile or put the battery on a charger. System is checked to verify alternator is charging properly and give the battery a load test. The battery is only replaced if it fails the load test.

 

I see.
Lexus Website will have all the service record. So if anything happen you can always tell them that you SAID it before but ignored lol
