Thanks for responding Tony. I have literally just sent a couple of emails making Toyota aware of this. It is an interesting one and I guess I will be about to experience what Toyota's customer service is like. As I mentioned in my post, it's the first time I've owned a Toyota, and after doing extensive research on options available, I specifically decided to purchase a Toyota based on drivetrain reliability and durability. I have owned other four-wheel-drive vehicles and SUVs and my main comparison (in terms of reliability and durability) is that I have been running more affordable Hyundais and Kias for the last 15 years (covering about 600,000kms) without missing a beat! And on top of that their customer service has been exceptional.
So whilst I am willing to endure the reality that some Toyota vehicles will inevitably have teething technical issues that will need to be resolved along the way, it will all come down to how Toyota deals with this issue. If they prove to be empathetic and willing to cooperate to try and find a solution then I'll be happy enough with that. If they adopt a stubborn, uncooperative approach then I guess I'll have a bit of an issue to deal with. For now I'll give them the benefit of the doubt.
Definitely have to agree with your consideration of reliability. Plenty of "high strung" performance vehicles that spend lots of time as "garage queens" waiting for replacement parts.
Only question that I feel confident to answer is that the supercharger uses the engine oil and does not have a dedicated supply. Based upon my readings, using quality engine oil with the correct oil viscosity is an absolute must. Also frequent oil changes because the high operating temperatures impact the longevity of the oil additives.
Excellent idea to thoroughly test what has been done particularly when you have had to do a fair bit of dismantling to get to the part to be checked/replaced.
Something that I do after an oil change is to recheck the oil level the next weekend or a few days later.
Just purchased a 2007 TRD Aurion 3500S, with approx 190000km on the clock. Car appears to be generally well kept and serviced. I've had a few older Camrys in the past, and always feel comforted by the Toyota reliability. I almost purchased a Renault Sport Megane 225 but the thought of reliability issues brought me back to sanity!
What should I be checking for in this Aurion to keep it running well? I've noticed on the forum about the oil sludge issues, so regular oil changes are a must. Does the supercharger feed off of engine oil or have its own dedicated supply? Thinking of a catch can from reading another thread on this forum.
What suspension mods would be a good idea for some occasional track work? Looking at Ultra Racing, they have some various braces. Which would be needed for the TRD model? What about poly bushes, are they needed, where could I get these? Ive also seen Titan coilovers for approx $1550, what are the quality of these like?
Also the centre console does not feel secure. It can shift laterally about 2cm left and right, which means it rattles around when driving. Have any other Aurions had this issue, and how have you guys fixed it?
Hi Tony, I understand your concern and frustration at having spent a lot of money and having to experience little niggles with it.
It's really difficult to say what it could be, unless someone here has actually experienced the same condition.
I tend to think it could be transmission related and not in a mechanical sense because everything is run by computers these days and when the software has a brain fart it can translate into a mechanical one.
I would definitely bring it to the attention of the dealership and perhaps take it back under a warranty claim. It's possible it may need a software update or something insignificant as that.
The old chestnut that seems to be the flavour of the day, is that people are saying that "I took it to Toyota and they could find nothing wrong". Don't accept it. If it's not driving as it should then they are responsible to offer a solution and fix it under the terms of the warranty agreement and consumer law.
Hopefully, it turns out to be nothing major. It's brand new, so I cannot imagine anything serious. Minor hiccups can occur with the high complicated electrical systems these modern cars have.
I'd hate to be a car technician these days to be honest. Issues like this can take you down a rabbit hole if you're not careful.
Let us know how you go.
My car does the same thing and it never bothers me to be honest. If there are no obvious leaks anywhere, usually checking when the engine is hot, then it's more likely it's just evaporation through the hoses.
It's not uncommon to have to top up the reservoir on the odd occasion. Water evaporates over time so the coolant level will never be constant.
Although they can look prettier, they don't perform as good as EPDM rubber. Sure they can handle higher temperatures, but when does your average car operate in that temperature range to warrant these anyway ??
High performance cars are usually fitted with silicon water hoses due to the higher temperatures produced. That's it. The major downside to silicon hoses is that they are much more porous than EPDM rubber. Why do you think they don't use silicon for fuel and oil ? You will lose more coolant over time a compared to stock rubber hoses. It's just dumb.
If the factory intended our cars to have silicon hoses, then they would've put them there.
At the end of the day, just stick to the original manufacturer recommended products and you can never go wrong.
Why would you want to introduce reliability issues in a reliable vehicle ?
