#16 of 104 Re: Huge repairs needed [bbart]
Apr 21, 2005 (7:30 am)
I have a '95 with 165k, bought with 82k in 2001. I have not had any problems with the power steering, other than a little stickiness at startup when very cold. Check the fluid level monthly, have yet to add a drop in >80k miles.
Same goes for the engine - no problems with gasket leaks or usage at all. I use Amsoil 0W-30 and Amsoil filters - change the filters at 12.5k miles or 6 months, and filter/ oil at 12 months, per Amsoil instructions. Oil lab analysis has shown this to be perfectly acceptable and in fact I could probably go up to 15k miles on the filter change. Other than top-off at filter change, the engine doesn't use a drop of oil. (Wish I could say the same for my Infiniti I30 engine - great performer but uses about a quart between filter changes - same oil and filters as in Avalon).
I have also drained the trans pan once, and refilled with Amsoil ATF (as I recall was about 5 quarts), and had the filter changed/ pan cleaned/ refilled one other time - was around the same amount of lube, maybe a little more. So most of the trans lube should be synth at this point. Even at the initial drain (90k miles), the fluid looked to be in fine shape, no discoloration or burned smell. However, I have no idea if it was original fluid/ filter or not. Never have to add ATF either.
Needed a cv boot when I bought the car (replaced whole axle at Toyota dealer, paid for by used car dealer) - but this looked to be due to a tear from road debris as opposed to a failure - other unit is original and in fine shape. Did the tie rod ends and ball joints 20k ago - but I blame this wear as much on the crappy roads around Detroit as any fault of Toyota. Just did the right side wheel hub/ bearing - ditto on the crappy roads. Neither of these repairs seem to be chronic issues with Avalon.
BTW my friend used to be a field engineer for Toyota, he said 250k miles should be easy, if general maintenance is followed and the timing belt replaced every 100k miles.
I put 16" 2004 Camry wheels and Kuhmo ASX tires (215-55/16) on last year - a nice combination although the tires are overkill for this car. Have 35k miles and still about 60% tread - not bad for a $75 (Sears) W-rated tire.
I will drive this car until the wheels fall off~ has been a great runner for me overall. 27mpg with mostly highway miles (500+ miles per week) at 70-80mph.
#17 of 104 Power train problem?
Mar 09, 2005 (2:42 pm)
Nowhere have I seen mentioned (with anyone else's car) a slight yet annoying (to me, at least) trait my 1999 Avalon has had since I bought it two years ago with 40,000 miles. When I touch the petal at moderate speed, or let off, there seems to be some slack somewhere in the drivetrain, slight though it is. Is this normal for an Avalon? Am I being picky?
Thanks for any feedback.

Interesting. My '99 XL did that sometimes. Not always, just every now and then. The car was flawless and drove as new at 92k when traded for an '03 XL. I never figured it out but it was noticeable when it happened. The '03 has never done it. Not much help here, except to say "you are not alone." There was a discussion about this long ago but it is not a current event so no one mentions it. And not all Avalons of the '95 to '99 model years did it. Try several tanks of premium fuel. (I did. No difference.) Some say it helps.

re slack, i remember reading a consumer's reports test on a 98 avalon and they mentioned the same "jerkiness" in the drivetrain, i have a 98 with the same problem but it hasn't gotten worse over the years so i live with it...petras
#20 of 104 Accelerator Problem
Mar 20, 2005 (11:52 am)
I have a 96 Avalon with 173,000 miles on it. It has been virtually trouble free. I am the original owner, and I have kept the vehicle maintained. However, I have noticed in the last few days that the accelerator appears to be hesistating at take off. It feels as if it does not want to go down, as if it is sticking somewhat. Has anyone experienced a similar problem or have any ideas what the problem may be?

Missy1, I have the same car with 162K miles on it but I haven't had that problem. You might try a shot of wd-40 at the throttle body where the cable attaches to the half-moon looking wheel. I did this to the cruise control cable and it helped.

I had a similar problem w/ my 99 Avalon. It was a lease vehicle and was fixed once at purchase (50 K ago) by the dealership. It has just reoccurred a few months back. I have not looked under the hood of a 96, but I would bet it is very similar to my 99. Progressing from the airfilter to the intake manifold: 1. airfilter 2. rubber boot 3. massflow sensor 4. rubber boot 5. throttle plate or butterfly valve. This is where my problem occurred. This is what the throttle cable works and gets gummed up from time to time. A $3 can of carb cleaner, a phillips screw driver and 10 minutes remedied my problem. You loosen the rubber boot just in front of the throttle plate. Be careful as you pull it back and usually you will have room to push it down below the throttle body to expose the throttle plate which will be tannish-brown. You may have to remove several other lines and perhaps an electrical connector. Use the carb cleaner and a rag spraying and working the throttle plate back and forth cleaning this area. Pay close attention to clean where the throttle plate meets the body - the valve is in a closed position. This is where the hesitation that you speak of is occurring. Let it stand for a few minutes allowing the carb cleaner to evaporate. Re-install the boot and any lines or electrical connectors that you unplugged to gain access. Start the car, you will have to run it at high idle - give it a little gas for the first minute or so, but the idle will clean-up quickly. If you are not comfortable with doing this, tell your technician at the next service interval that you would like to have the throttle body cleaned.
I hoped this helped - it may not be the solution, but it would be the first/least expensive area I would look at.

I had the same problem on my 98 Avalon. Before you purchase any carb cleaner, make sure the bottle specifically says, "Throttle Body Cleaner". I cleaned with Valvoline Synpower Carb Choke & Throttle Body Cleaner. I did this once and about 2k miles later it started to act up again. So I decided to remove the throttle body from the engine and clean it really good. When I remove the throttle body from the engine, I noticed that there are two butterflies, one by the rubber boot as mentioned above and the second is on the opposite side of the throttle body. You can access this by removing a plate. I cleaned and cleaned, make sure you purchase as small brush (toothbrush will work) to clean out thoroughly. I reinstalled and the car drove like new. About 5k miles later, the car started to hesitate again while driving, especially bad at idle. I did some research and had to replace the Exhaust Gas Recirculation (EGR valve). At a cost of $380 dollars, I did it my self. Three screws and a wire harness. 8k miles and no problems. If I was in your situation, I would recommend the following, if you haven't done so. Replace spark plugs with OEM parts, DO NOT PURCHASE BOSCH PLATINUM PLUGS, plug wires, PCV, and fuel filter. This is what you call a car's spring cleaning schedule.
#24 of 104 98 Avalon Transmission Shifting Hard
Mar 21, 2005 (6:21 am)
I have 72k miles on my Avalon. I had the trany fluid changed around 65k and noticed it is shifting hard from 2nd to third. When it is cold outside, the trany lags in 2nd gear until the thermostat temp is at its warmed up point. The fluid level is the correct level. Any suggestions??
#25 of 104 Checking the transmission fluid
May 13, 2005 (8:13 pm)
Does anyone know whether you need to keep the car running to check the transmission fluid on an '03 Avalon? This information is usually found on the dip stick, but mine doesn't specify whether you need to keep the car running or not.
