Toyota Sequoia Engine Questions



  • I've read on other forums the CEL is very common, especially with the 4.6 engine. Almost to a person everyone who had the oil changed has not had the issue return. Now as for the 5.7 engine doing the same thing, this is the first I've read about it.
  • I just noticed that on my 2010 SR5 5.7 the oil pressure increases significantly on acceleration. I've never seen this in a car before. Not sure if its related to your issue. I have 750 miles and no check engine light. Otherwise the truck is great!
  • emnem75 et. al.
    Just got a 2010 5.7L SR5, curious about any later followup after initial CEL?
  • fedflyguy, a follow up. After all the initial check engine lights, the oil was changed and the light has not come back on. We talked to a Toyota rep and he said that the new 2010 sequoia has a redesigned oil control valve and that it is not working properly in some vehicles. He also said that they probably would issue a recall but that they have to manufacture a new part for the engine before they do. They still are saying that it does not affect the driveability.
  • No light since the 200 mile mark. 3100 miles now. No oil change

    Hi all. I have been considering buying a 2010 Platinum and have been posting over in the Prices Paid board, and I just saw this discussion. If you are experiencing a Check Engine Light problem, then you need to read what I say here and keep good records. Back in 2003 when we bought a Pathfinder, we had an identical problem in the first few thousand miles that drove me crazy with multiple trips to the dealer, wasted time, and conflicting explanations. What you need to know here is HUGE: in most states, if you have to take a new car to the dealer 3 times (I think that's the right number) for the same problem, and they can't fix it, then you fall within the Lemon Law . . . and it does NOT matter if the car is driveable or not. Simply put, even if driveable (my Nissan was deemed driveable as well), you are entitled to invoke your state law rights. Trust me, the dealers will try to intimidate you, but read up on your rights. Once you give them the Official Lemon Law Notice letter, they have 15 days (at least in my state) to fix it 100%, or they must buy the vehicle back from you for full price, plus reimburse you for all sorts of other things. This applies to ANY sort of defect in the vehicle that diminishes its value, including a Check Engine Light problem.

    If they have attempted to repair your Check Engine Light problem twice without success, then one mention of "The Lemon Law" to the Consumer Affairs' folks will get their attention as they will probably send a regional repair expert in to make sure they fix it on the 3rd try. A Check Engine Light can be a major annoyance on a brand new vehicle, and don't let a dealer try to belittle it. I don't remember all the details of the Lemon Law, but I gave an enormous amount of detail in the Nissan Pathfinder Maintenance & Repair forum. See:
    The summary of my experience with the Lemon Law and Check Engine Light can be found at Posts 672-678 in that forum (and also a copy of the letter that I used threatening to give them the official notice). Knowledge is power, and believe me, if I shell out over $50K for a Platinum and have to go through a Check Engine light experience with Toyota, then I will not waste anytime in exercising my rights.

    In the end, Nissan resolved the pesky Check Engine Light problem, but I was able to get Nissan Corporate to give me (in exchange for not Lemon Lawing the vehicle) (1) a 5-year platinum gold total service contract (maintenance every 3 months, with free car rentals even at major oil changes) and (2) a 7-year extended warranty, both of them for FREE. The value of those two things was worth thousands, and it made living through the Check Engine Light problem much more "palatable." :)

    Check it out and Good Luck.
  • Thanks for the info. Unfortunately for us, we were told, by a toyota representative, that if you went through the arbitration with Toyota and lost you could still pursue the lemon law afterward. We opted to go through Toyota, naively figuring they would want to make this right, after all it was our 4th new Toyota purchase and our 6th Toyota vehicle in the last 16 years. , besides we could always do the lemon law after if we were not satisfied. We lost our arbitration and then found out that in order to invoke the lemon law in our state that we would have to have the check engine light come on an addditional 2 more times. Well, we now have 7700 miles and no check engine light but the whole experience has diminished the excitement and joy of owning this very nice vehicle. Believe me we will not be faithful, loyal Toyota customers after this.

    Sorry to hear that.

    Yes, over time, I have changed my approach with car manufacturers (and the dealers to some extent) from a trust & "kill them with kindness approach" to a no-nonsense, business, firm (but not rude) approach. As for loyalty, it got me nothing when I recently tried to have a steering wheel radio control replaced under my extended warranty with Nissan. Even being an attorney, there was no way I could get anyone at Corporate, or the 3rd-party company who backs the warranty, to cite any specific language in my actual contract excluding the repair (and the dealer even agreed with my interpretation). My option was small claims court, which I ruled out as a waste of time over a $300 repair.

    But points being: (1) these guys don't care about loyalty; (2) many of these extended warranties (after much legal review of the fine print) on average are not worth it IMHO (fortunately, I paid $0 for mine); and (3) I will never buy a Nissan again based simply on that experience with Nissan Corporate (and that is despite the fact that the vehicle has performed well over last 7 years). [Irony is I am no longer buying Nissan, so I am now looking at Toyota, while you are fed up with Toyota and may now be shopping elsewhere, perhaps Nissan. :) ]

    So, long story to my point: any time you have experienced at least 2 failed attempts to repair the same problem (no matter how small) on a brand new vehicle, I would recommend to all that they do their own independent check of their state's law (lots of stuff online, do not rely on dealer's or Toyota's representations) and then raise the Lemon Law threat immediately . . . in a professional and fair, but firm way. Until you get the attention of the right folks, and until they get the impression that you know what you are talking about vis-a-vis your state law rights, then you can easily get the run-around with a lot of wasted time and trips to the dealer with ever-changing explanations like I did (and perhaps you did).

    I will never go through that game again on a new car. Dealer gets 2 tries, and then its time to start standing up for my rights and tell these guys they are on the verge of buying the car back for full price, plus reimbursing me for lost time, wages, attorney fees, and even the cost of after-market accessories. And, like you, I have found loyalty counts for zip with these guys.

    I wish every merchant could be as fair and customer-friendly as, say, a Nordstrom's! :) But, that's not the case unfortunately.
  • 9 times out of 10, its the gas cap causing the CEL to come on. Next most frequent cause is over-filling the tank and flooding the carbon canister on cornering.

    Dont top off, and tighten the capp 3 clicks.

    My 05 toyota sequoia sr5 has an issue with rpm dropping during moderate acceleration,such as merging to hwy speeds. The drop is about 50 rpm for about a quarter of a second and repeats at a regular interval of about one second. It is not intermittent, but very regular. I have replace spark plugs and air filter with no change. Car runs great otherwise. A mechanic suggested it may be related to the magnetic accelerator system Toyota uses. Anyone have a similar experience or a solution?

    My ex wife was borrowing my 2003 Toyota Sequoia which has been running fine. Today she went to start the car and the security key light was flashing on the dash and the relay under the hood was cycling. It appears that the system is immobilized. I tried the spare key but still nothing. The light stops flashing when key is turned. Did flashing light drain the battery or is this a damaged key chip?
  • My 2003 Toyota Sequoia has an ignition problem after getting into a wreck. Everytime i turn the key to start the car, it will start but then it dies right after. Anyone know what could be causing this issue?
