Avalon 2005-12 :: Engine Knock - Strong Vibration Stinking Bad Sounds
Sep 17, 2012
This morning I went to start my avy and it ran poorly for about 30 sec (strong vibration stinking bad sounds) than started knocking loudly. It ran great when I parked it. I read that it could happen from poor quality gas, which I got gas the last time at a super run down gas station that still had rolling digits for the price I also used seafoam in the tank, could that be why? I took it to the dealer already which is about 30 miles after the car was warm it ran great.

So, I have my check engine light and the code is p0327 (knock sensor). Clear cose but it returns. Going on for 3 days now. I was suspicious that something else is going on. I also remembered I've been using a little more antifreeze in the reservoir. So, today I needed to watch the coolant. I ran the car for an hr and I found a lot. Red coolant on my belt, the back passenger side of my engine and it was caked on with coolant. I think the water pump is going up.
I was concerned that coolant was also leaking from the intake manifold but it's only the right side, so I'm pretty sure the coolant is being slung around from the belt. I rinsed the engine down and the knock sensor code went away. Temporarily, until more coolant got back there. Do you think I will need to replace the knock sensor along with the water pump or should the sensor work ok after some intense cleaning after the water pump replacement?

I have totally insulated my 2013 Avalon XLE with the sound deadening materials. Now, I can hardly hear or feel any engine noise or vibration at any speed unless I really accelerate the engine hard. I have also insulated my wife's 2012 Camry LE but I have not been able to eliminate the typical 4 cylinder engine buzzing sound and vibration intruding into the cabin. I am wondering if the Avalon Hybrid does the same once the 4 cylinder engine kicks in even though it is better insulated than the Camry.

I'm the original owner of a 2005 Mariner (3.0L V-6, 114K miles). We live in Central TX, so we are just starting to experience cooler weather (40's - 50's at night, 60's - 70's daytime). At this time of year and through the winter, this Mariner develops an annoying rough idle. It is more like a strong vibration when in Drive or Reverse, not really a miss in the engine. Increasing the idle speed with the accelerator pedal works, and it does get somewhat better as the engine gets to normal operating temp, however if the day is cold (30's or 40's) it doesn't get better.
I've changed the plugs, changed the IAC valve, and cleaned the MAF sensor a couple of times, with no improvement. We almost exclusively use Exxon or Chevron gas, which should have good fuel-injector cleaning additives, so I sort of doubt the injectors are at fault. I've had a local mechanic check to see if any codes exist, but nothing shows up. This has gone on for 2 or 3 years, but it was not like this when the car was newer.

We have gotten a record breaking amount of snow this winter and it has been tough on the smaller vehicles. The last couple days my car has developed an odd issue. When I start the car and it is not warmed up as in there is only one bar on the engine temp meter, I put the car into reverse but don't take my foot off the brakes and the car starts to vibrate strongly. Once it's warmed up to a few bars it operates normally. I know the brakes have some ice on them too but that is a different matter, also there is snow/ice packed into the underside due to the amount of snow on the roads here.
Car is currently parked in my garage with the heater heater on so hopefully it can melt some of the junk from the underside by tomorrow.

I am on my 4th Avalon and have loved everyone. This newest one, however is experiencing a slight steering wheel vibration intermittently at 70-75 mph. It also does not seem to "track well" at this speed. I have to work harder to drive this than my wife's Suburban.
Neither one of these problems is "severe", but aggravating and worrisome. The vehicle has about 2000 miles on it. I am taking it to the dealer tomorrow and my fear is all he will do is the balance the tires (and maybe that will do it), but I am afraid the "tracking" issue may be more involved. It almost seems like there is a slight amount of play in the steering wheel.

My 05' scion xa has always had a problem with vibration and some vibration sounds when stopped at a light or parked but both go away when i put the vehicle in neutral. It got so bad at one point the seats would shake, i took it to toyota and they replaced all the engine mounts. The vibration isn't as bad but very noticeable. Could it be the A/C? The problem exists with or w/out the A/C on including the heat.

My 2008 XLS has 172,000kms on it and has been having a vibration problem. Specifically, the gas pedal vibrates and the whole car shudders when it is between 55-80 km/h and in 6th gear. The shudder/vibration occurs when the car has to drop a gear to accelerate. After it downshifts, the vibration is gone. It has been happening for the past few months. The vibration did go away for a while after I changed the brakes. So, not sure what could be going on there!

I have a 2005 Limited and whenever I roll any of the windows down it does a quick rattle vibration like its trying to pull away from something that's sticking then it continues to roll. It would be 1 thing of it was just 1 window however its all 4 windows. I thought originally thought maybe some of the rubber molding I seen on the windows, (maybe from the days it was hot over the course of years) were the reason and wiped all the black stuff off the windows with goop. Didn't work. I didn't realize how bad it was until I moved my old 2001 Avalon I'm selling and they rolled down so smooth..

Vibration in steering started in January soon after full brake job, new rotors, etc. on my 05AvyXLS. Pronounced between 60 and 70 mph where steering wheel shakes in my hands. Had tires balanced and rotated 3 or 4 times, alignment, checked tires/treadwear, in 3 diff stores (incl dealer)...same problem. Just bought new set of tires today, thought prob would go away since all pros thought was a tire prob...negative. Same prob, only even more pronounced!
I'm thinking I have a tie rod, wheel bearing, strut/shock, or some kinda suspension prob? I've spent considerable dough with exactly the same prob. And could there have been something related to the brake/rotor job? My pro says no, unless there is vibration when I brake, which there is not! Vibration occurs b/t 60 and 70, whether I'm in the gas or not, and does not happen when braking! What can this be??

Recently we purchased a 2011 Avalon Limited. 2 weeks later while driving locally, I noticed a vibration in the car. The vibration appears approx 37-38 mph, and continues up to 60mph. At 70 mph the ride is vibration free. Our car is still under warranty, while at the local dealership, questioning the vibration, they notice a "code" for the transmission. They replaced the transmission. We still have the vibration.
The following week they "force balanced" the wheels. We still have the vibration, now it is stronger. I am almost ill with the vibration. I actually feel it, not just a visual issue. There is a Tech report on the issue, with another Avalon experiencing the same issues. What the issue could be? Michelin Tires. This is our 4th Avalon. We have owned a 96 XL, 2001 XLS (the best!!), 2006 XLS, and now, after waiting many years, I was able to purchase the loaded Avalon Limited. Only to have issues that make me sick when I drive it!

I know that if the shifter/transmission is set to "S" then it tends to use the engine as a braking system sort of like a manual transmission. My problem is that it does this while in "D" (drive) for about 5 seconds and then it back to normal as in it's like it's put back into neutral. I read the manual and it states that when you place it in "S" mode and then back to "D" mode it retains some of the "S" features such as engine braking, but in our 09 Avalon XLS, it does this all the time while in "D".
Question: Is this normal for engine braking for about 5 seconds while in drive mode?
If so is there any way to get it back to a normal automatic drive mode where as when you release the gas pedal it coasts without engine braking?

I have a 2005 Avalon with a 2GR-FEV6 engine with approx. 130,000 miles on it that ticks or chatters for about 2 seconds at startup. The sound is coming from the #2 bank directly below & forward of the oil filler cap (forward most bank, right side). The sound is only present after the car has been sitting for 2-3 hours or more and relatively cool right before startup. There is no other drivability issues such as reduced performance, power or gas mileage. It's not throwing a fault code and the symptoms began within 5000 miles of changing to Royal Purple synthetic oil at 110,000 miles. I don't know if that is a coincidence or the reason for the ticking.
My initial thought was a faulty VVT-i oil control solenoid/valve but I pulled it out, put 12 volts to it and it worked fine. My second thought was a possible clogged VVT oil screen or filter. give me the possible symptoms of what a clogged screen would do? Would it cause the VVT-i actuator to lag just long enough to cause this noise since the oil needs to get through the screen to flow through the oil control valve to affect the operation of the VVT-i actuator and if so what is actually making the noise? It sounds like rocker arms slapping but just in that one spot.

I am driving a 2007 Avalon XLS with about 71,000 miles. These lights came on together yesterday. After consulting this forum, I checked the gas cap and found it was indeed loose (or at least had not been engaged with any of the "required" three clicks.) I closed the gas cap tightly and restarted the car. The lights promptly came back on.
I drove to AutoZone where someone pulled the codes: P0306 and P0356. They gave me a printout suggesting the number 6 cylinder was misfiring (P0306) and an ignition coil circuit fault (P0356).

I have a 2009 Avalon that is displaying a Check Engine Light and a VSC light. Is it possible it is doing so because I have two different brand tires on the front hankook and the back Michelin?

I have a 2008 with a tapping sound from engine - Sounds kinda like a diesel engine when cold. Not real loud.
It stops once the engine is warmed up. Is that most likely a tappet?
88,000 miles... I bought it two months ago with an extended warranty.

I have a 2005 Limited and when I start there's a slight hesitation then the power comes on. Also, when I let off the gas and the car slow's to about 20 and below there's a little "reverse surge." The power starting out and decel'ing isn't linear. It's got a little hiccup.

I did a search but found nothing on a coolant leak. My 07 (57K) has developed a leak on the passengers side of the engine. Not sure if its the water pump (not making noise) or the themostat housing as a mechanic who took a very quick look at it suggested. How hard it is to get to the thermostat housing? Anything else have to come off? I don't have a FSM.
