Toyota Tundra Problems



  • So the fan coupling makes the truck exhaust sound differently? I cannot even imagine how this would change the tone of the engine inside the cab. Could you explain further?

    Sounds like piston slap to me.. ...just kiddin..

    I think the theory on the fan clutch is an interesting thought..

    What type of oil filter does the Tundra use? On Ford vehicles the oil filters have an anti-drainback valve to help hold
    the oil in the top end when the truck is sitting for a long time.. Without this, the engine will knock on startup for a second or 2 on the first startup after sitting 10 hours or so.

    Since the fan is viscously coupled it takes a few minutes in cold weather before the fan disengages. While it is engaged quite a bit more noise comes from the engine compartment. This may be mistaken for exhaust or engine noise. Open your hood right after you have started your engine. Have someone rev it to 2 - 3 thousand RPM. It will seem like a hurricane. Drive the truck a few minutes and repeat this test. All you will hear is the engine and exhaust.

    This does not explain the diesel noise that some people claim. Since neither my truck nor the other Tundra owners I know trucks do this - I cannot even attempt an explanation. I think it must be a very rare occurence.

    Duckcaller; a diesel like sound is the best analogy I can come up with. My Tundra does not make a diesel like sound while idling after a
    cold start. It's rather a clicking or tapping sound sort of like a sticking hydraulic valve liter. The hammering, diesel like sound only
    occurs after I back out and accelerate up to the
    25 mph speed limit on my street. In other words,
    the sound gets heavier in direct relation to the
    load on the engine.

    Man you drive a lot of miles! 63,500 in 8 months - what are you a cab driver Or do you have a 130 mile one way commute! (lol) You must burn almost a tank of gas per day.

    Bamma I thought the fan clutch was designed to disengage when engine was cold, and fully engage when engine gets hot. You could be right on the Toyota, but it seems backwards to me.

    I agree 100% with Dale #65 of 66.I have brought my truck in to have it checked out. And the service manager said it's a normal condition. I'm sorry but I don't believe that. this is my 4th toyota truck and they never sounded like this.
  • z71billz71bill Posts: 2,000
    I know the Tundra was designed to have low oil pressure at idle - when the engine is cold what PSI does the gauge show. Could these two problems be related? Maybe low oil pressure & cold engine combined make the engine sound.
  • I have a delivery service. No they didn't give me any idea of why the transmission went out. The axle was because they tried to convince me that the wheel bearing noise was just tire noise. When the seal went bad, it scored the axle.
    I previously owned a 96 Tacoma X.-cab that I put just under 300,000 miles on in under 3 years. It had a transmission replaced at 42,500 miles. I had NO further problems with it. I bought it used with 16,000 miles on it. My overall expense for maintence was 4.5 cents per mile. At about 200,000 miles, I did have to put a wheel bearing in the right rear. My mechanic said that those things happen from time to time, but are not really usual.

    I have a 2000 tundra with 18,000 miles. I've had
    it for 1yr 3 om. I live on long island and have
    experienced the diesel sound on really cold day
    during the warm up and driving.
    On another note. does any one have any problems
    with wheel alignment? I have sent the truck in twice and have a problem where the outside edge of the tire prematurely wears.
    Toyota claims that there is nothing wrong with the
    alignment. I have checked tire pressure and it is
    set to recommended lfs.

    I have been trying to locate a Tundra with AS brakes. None of the dealers in my area have any and they tell me that I have to place a special order to get one. Have any of you had the same problem? Is there a problem with Toyota AS? The dealers tell me there is no demand for the system. I don't understand how they no there is no demand when they don't have any trucks available with the option. Most buyers buy something available on the lot, they don't special order. Your comments would be appreciated.

    Anyway, when I got my Tundra, the majority of the Tundra on the lot had ABS. I didnt look at them all but the ones I looked at had ABS. I thought it was standard back then because of the stock the dealer had in the lot.

    There must be some geographical planning going on with Toyota to load up ABS equipped Tundra's here and you have to order it there.

    By the way, not a Tundra problem yes no? A dealership lot/stock issue?

    I'm buying my 1st Toyota truck I'm getting the 4dr Access Cab SR5 V8 2WD
    Since the dealer I went to didn't have the truck he searched for it and found one
    in the area and went and picked it up.Now he tells me the dealer who had it
    didn't replace the brake pads per some factory memo or something on
    replacing the pads and shoes the truck came with. So he says they will do it
    and turn my rotors at the same time to make sure everything is OK. Anybody
    heard of this happening to them?
  • ratboy3ratboy3 Posts: 324
    I would be weary of such thing. The vibration problem has been mentioned here before and I am guessing the dealer felt this vibration on that particular truck.

    I wouldnt take that particular truck myself. Problems exist, fortunately for me none so far.
  • rocker5rocker5 Posts: 1 " check engine " light just came on after 33200 miles.
    ..tundra is still running fine. Is this likely a service gimmick ?..
  • duckcallerduckcaller Posts: 107
    Whoa! "Check Engine" can be very, very bad - or just the emissions control system - or a defective sensor. Until you figure out which - I would be very careful. Check all the basics - air, fuel, oil filters looking for a stoppage or a line break. Truck may seem to be running fine... but you need to find out why that light is on.

    My wife's Dodge Caravan "check engine" came on one time and I found the fuel filler cap was loose. I refilled the tank and snugged the cap tight - and the "check engine" went out.

    "Check engine" came on once in my old 4Runner - but it had some kind of diagnostic thing that displayed codes through the radio face. My charcoal air canister thing needed to be replaced. Replaced it and the light went off.

    A bad tank of gas - I'm told - can also cause "check engine." Clogs the O2 sensor?

    It's not a dealer gimmick, though. Check your engine.
  • ryanbabryanbab Posts: 7,240
    Go to your dealer and they can do a diagnostic check on it. It wont cost you anything its still under warranty. They can tell you whats wrong. Something even if it is minor is wrong. Just like duck said some vehicles now have a thing where if the gas cap isnt on tight the light will come on.
  • toddstocktoddstock Posts: 268
    the fuel air mixture can be off and that can cause the light to come on also...

    good to have sooooo many "shadetree" mechanics on!
  • ratboy3ratboy3 Posts: 324
    hehe.. I watch that show.. they moved on to a more sophisticated shop I think..
  • ratboy3ratboy3 Posts: 324
    Truck has about 10,500 miles. I am now a member of the warped rotor club! wahoo! grr..

    Noticed the past few days now that on crawling speed. When I slightly apply the brakes to slow down even more, the brakes acts like it catches then let go.

    It's in the service dept right now. Took it there before it gets worse. Or maybe the numb nuts there will make it worse. I mentioned that I too have the warped rotors and he gave me the 'what you talking about Willis?' look.

    I just smiled and told him to just fix it.
  • ratboy3ratboy3 Posts: 324
    Dropped off the truck at 7 AM. I got it back at noon. Service guy followed whatever he needs to follow on the TSB.

    They put in new set of updated drums and rotors, and pads. The drums were warped for sure but the rotors were good. He said they replace all 4 assemblies and ship them back. Dunno where, I didnt ask.
  • In reading some of the previous posts on ABS problems with the Tundra, I was wondering if the screeching tires you heard in addition to the black marks were a result of emergency trailer brakes that kick in during emergency bracking.

    I know some trailers have one of two types of systems to increase stopping power. One system is pnuematic and is evenly applied as you step on the brakes.

    The other senses when the trailer tongue slams forward and sends an electrical charge to the trailer brakes. To use a bad analogy, like blocking your nards when your 4-year-old nephew has just "learned" karate. Ouch.

    Anyway, you may want to check the marks on the road. Are they consistent with your Tundra's tire width or your trailer tires???

  • duckcallerduckcaller Posts: 107
    That happened a long time ago... last summer. And I never looked back to see if I left any marks. Like I said, I believe the back tires locked, but the front did not. I maneuvered through the skid. I can't reproduce the rear lockup on wet pavement and I can't say I'm not pleased with how the system works otherwise. So it may be related to the trailering - I don't have trailer brakes.

    the 2001 tundra access cab 4x2 i recently purchased came with the rear axle shifted .25" to the right side. this is obvious as the right wheel sticks out .50" further than the left. when i took this matter to the dealer(who was very helpful) we measured almost every tundra in the lot, from the frame to a consistant groove in the tire. we found every silver(like mine) colored one to be also offset, while other colors were deadon...NO I AM NOT MAKING THIS UP!!! the service mgr. call toyota, and the reply was "only a quarter inch? a half inch is normal". well, if toyota thinks this is within their tolerance, it sucks. i would not want a vehicle with this kind of defect if i were looking to buy, can u say dogtracking. buyers of tundras arm your self with a tape measure and do NOT accept defective products.

    I have a 1985 Toyota pickup. I used to use cheap gas in it, and the check engine light would come on about once a month. It would stay on about 5 seconds, then go out. Checking the reason for it coming on is a lot simpler that in the newer cars, and it turned out to be the O2 sensor. I replaced the sensor and switched to Texaco 87 octane gas and it hasn't come on since (over 10 years). We now use nothing but Texaco gas in our 3 vehicles. BTW, I don't work for Texaco.
  • duckcallerduckcaller Posts: 107
    Not sure about Texaco products... I fill up at the "mpg" station down the street because it's the cheapest gas I can find. I've heard that tankers will go from station to station pumping 87 octane and that, short of the "boutique" gas with higher octane, it's all the same. It is possible, I've heard, to get just ONE bad tank (and this can come from any gas station) that will screw up your O2 sensor. Water leakage, etc, could be the culprit. I just am not an expert on the gas front. When I lived in Toledo, OH, I used to tank up at the Sunoco station next to the East Toledo refinery - they advertised "refinery fresh" gas. It was more expensive, but I always felt like I was taking good care of my car by tanking up there.
  • cub4cub4 Posts: 11
    I used to believe that Texaco gas was the "Star" in my road. I would go out of my way to find a Texaco station. For years I used abslutely nothing but Texaco until I started having problems with my fuel injection, throttle body gunk, and O2 sensor problems. The mechanic said my problems were due to using cheap gas. What nerve! When I sent a letter to Texaco explaining to them my problem they basically said I was SOL and that they couldn't do anything for me. I now use the cheapest gas I can find and add a bottle of STP every once in a while. Never had problems since. Also, it is true that the same tanker will deliver the same gas to different brand gas stations. What I've been told is that each station then adds their own additives to the gas. Bottomline, don't trust them. Buy the cheapest gas you can get and use third party additives like STP once a month or so. That's just my opinion. Also, a big NO NO, never ever fill up when a tanker is dumping gas. It stirs up the sludge in the storage tanks and ends up in your engine. Find another station.

    I have noticed that it states to have the front tires at 27 psi and the back at 35 psi.... What do you all run your Tundra's at... I don't tow as of yet... Getting a boat this summer, but no towing as of now... TIA
  • ryanbabryanbab Posts: 7,240
    dont you think it would make sense to have more air in the front tires? There is more weight acting on the front end than the rear. Unless loaded (stuff in the bed) down the front should have more or the same amount as the rear tires
