Thank you for the feed back.

Hey David try yours with the passenger window down and let me know how you go.

Can anyone with a new Camry Hybrid 2012 answer this question.

Is anyone experiencing a high pitched noise from the left side new Camry Hybrid?

I have this noise on mine. Especially noticeable when driving past any objects on the left side of the car with the passengers side windows open. Its like a high pitched electrical noise. It just does not seem normal. I have been advised it is the inverter but its way too loud. You just can't drive with the passenger windows open. The noise will drive you nuts.

Any feed back is really appreciated.

I have a Camry Hybrid HL 2012 and I find the inverter is noisy. Does anyone else notice this? I observe the noise when driving under 40kms with the passenger side window open. The high pitched sound will bounce off any houses or walls I may be driving past. I also noticed it going down the freeway doing about 80ks and it was bouncing of the concrete barriers in the middle of the road. Its pretty obvious to pedestrians I drive past as they all look to see what the noise is.

Is this normal? Am I being too picky?

Any feed back is appreciated.

I purchased the 2012 HL Hybrid about 6 weeks ago, Done 2500 kms and getting a bit over 6LT/100Kms. I estimate getting just over 1000kms per tank of fuel. This is with 50/50 city highway driving.

Hello all

I have an Aurion V6 2007 which has a noisy engine on cold start. Details below show a possible solution.

Just dropping some info on some recent experiences I had in determining the cause of a noisy engine on cold start up and continues until "FULL" operating temp. I am sure there are many drivers that have had a similar experience. The engine sounds like a diesel for the first 10 minutes of driving and slowly the noise smooths out. Drives you nuts!!!!!

I spoke to Toyota technical division and they have confirmed there is a paper which details the reasons for the noise which is very likely piston slap. From what I can gather from the info, the noise may be piston slap due to a greater gap between the cylinder and the piston when cold. I was advised this is normal. Not happy to just listen to the noise, I tried some other solutions. You may notice the oil that some service places use is 5W-30. This is thin oil and I found did not help the noise at all so I tried using Penrite 20W-50. This rating is acceptable as per the owners manual.

The difference was amazing. So much quieter. Easily a 100% reduction on noise levels. Obviously this will differ depending on the mean temperature on where the car is being driven. I hope this may help any fellow Aurion drivers out there with similar frustrations...

Hello

I have the occasional noisy valve lash adjuster on a Toyota Aurion V6 with 32,000KMS. Sounds like a noisy lifter or tappit.

The noise will vary on the temp of the engine. Cold is worse. Is the cause of the noise to do with the faulty valve lash adjusters?

I know this is a source of annoyance for the odd Aurion V6.

Is it easy and or cheap to change these for a new item or a better model adjuster???

Does the HDT models use the same system?

Any ideas would be appreciated. :o

Sounds like messy engine building to me.....

Surely Toyota can build an engine that wont have issues such as these its not like Aurions are cheap

I agree. They should have done the research on this one.

I have a Honda Euro 2008 which is cheaper that the new Aurion I have and it just sings every time the motor starts.

Cold or hot its perfect. I drove professionally for 15 years and never came across this noise in a new car.

Maybe in a 20 year old Falcon...

My Aurion V6 engine has done 28,000 Kms with oil change very 5K and is just worn in...

I expect more from an engine.

Putting all the negative comments aside, the heavier oil has made the difference and hopefully for the long term.

I wasn't referring to the owners manual but the actual 2GR-FE service manual (which actually recommends 5W30, but in Aussie climate, 10W30 is no different). I apologise that I wasn't more specific there. As for the grade of oil, if you just wanted to solve the cold start issue, why not move to a 15W40 so that the oil is not too thin when cold and should fix the noise, and not too thick when hot so as to reduce economy?

The thing you need to remember here is that when it comes to a cold engine, the first number in the viscosity rating is all you need to worry about. The second number though is where you need to be concerned. The primary issue that you may come across is that you may experience less economy because the heavier oil will flow less easily. In addition to that though, the ticker oil has the potential to disrupt the oil flow characteristics of the engine and may even create higher than normal oil pressures.

But that said, this is my personal opinion from the way that I have learn't about it all working. If you are satisfied with the 20W50, then continue to use it then. I'm not going to stop you, I would just rather stay close to the engine recommendations.

Thank you for the feed back. I appreciate it. All good...

Come winter I may scale down to the 15W-40. With the high 30s we are having the 20W-50 works a treat.

Maybe Toyota will take note of the many annoyed drivers who put up with the rattle and clunk.

There has been so many denials and comments about it being "normal". Yes... Is it NORMAL based on a design fault with the engine?

Just like if I was blind. Would I will walk into walls.

You may notice the oil that some service places use is 5W-30. This is thin oil and I found did not help the noise at all so I tried using Penrite 20W-50. This rating is acceptable as per the owners manual.

Logically, yes that thicker oil will reduce that noise, but that oil is far from the recommended oil for the 2GR-FE. The recommended oil is 10W30 for most Australian conditions and I wouldn't want to go any thicker for the oil. You may be reducing the noise and having greater peace of mind, but you could also unknowingly be putting extra wear on your engine. Also, there has been some discussion over on the Aurion boards.

Piston Slap in Aurion

Rattle in start up

Hmmm Does not sounds right.

Your comment in relation to the 20S-50W and I quote "that oil is far from the recommended oil for the 2GR-FE" does not go along with what is "recommended" in the owners manual. I spoke to the technical division at Toyota and they confirm using 20W-50 can be used as per the manual. In the manual there is no reference of 10W-30 being the general recommended oil. Toyota technical division said to check the owners manual and based on the "mean temperature" that the vehicle drives in, then use the suggested oil accordingly. The 20W-50 lists as temps from -7C to 38C. Sounds like Australia to me.

I can not see how this 20W-50 oil could put extra wear on an engine? The fact that I am hearing piston slap, worries me more from an "Engine Wear" point of view. The idea of these metals behaving like this only brings up the thought of wearing in my mind! The clearances may be too big at cold. I have never seen this in a new car ever! The noise should NOT be there in the first place.

I have no doubt that my Aurion V6 engine runs like a dream since I put the Penrite 20W-50. Cold start noise is 80-90% less. The time taken for it to really smooth out is 2-3 minutes of driving instead of 10-15 minutes. I have gone from wanting to sell it to happy to keep it. (and by the way - I do not work for Penrite. They just make good oils)

Thank you for the suggestions and feedback.

I am getting Toyota to check the thermostat and valve lash adjuster assembly on Tuesday.

I will post the results for future reference...

Thank you for the reply...

My Aurion behaves a little weird. I do let mine idle 5-7 mins to get it to warm up. I did not know it should be driven.

I did try the driving to warm up method and found it was just so noisy. Whilst driving to warm up, I suspect it was either one or more of the valve lash adjusters was taking a long time to get going or the engine was pinging or a combination of both. It drove me nuts... The noise would continue for 10 mins of driving time and then slowly settle down. Once the car is hot is sounds relatively smooth.

Was it maybe the on board computer taking a long time to sort out the fuel mixture with prolonged pinging from the engine???

You mentioned yours gets to operating temperature quickly. How long does it take for the temp guage to get to the horizontal position?

I can only assume the thermostat and valve lash my be faulty?

We also have a Honda Euro and it is perfect. No excessive engine noise and heats up in a blink of an eye...

Can anyone confirm how long it should take for an Aurion V6 3.5L to warm up in cool weather of around 8 Deg C?

My engine is so noisy until it warms up. It sounds like one of the valve lash adjusters clatters until it gets really hot.

You have to wonder if is it a deisel engine!!!!

Has anyone had this problem?

I have a 2007 Presara with 18000 on the clock...
