I've had my RZ Camry since new (2017)
The "jarring ride" is due to this car having a "sports suspension"
This is part of the difference between the RZ and say the base model.
So whilst the turning circle is unchanged compared to the other Camry's and is still not great compared to say a Subaru Liberty of the same production period, it "hugs" the road better then other Camry's (of the same year model)
So it feels "less boaty", and more stable on the highway, especially at the higher speeds.... or so "I've heard" 😂
The SL is a completely different car, the last of the Australian built Camry's were in 2017,
They then "changed shape" a.k.a completely new car in 2017/2018 and these were built in Japan
The "SL" is part of the "new range" that is built in Japan
Changing tyres / having them inflated to the "correct" pressure may help, but on the whole and I'm not sure how else to put it....... but that's the "traits" of the car that you purchased.
As an aside, please ensure that you have been doing the "in-between" oil changes and using a full synthetic oil 🙂
So depending on your budget, it may be time to change "rides", which if this is the case, check what your car is "going for" to see if trade in value or selling the car privately is the best option.
I hope that this helps 🙂
I ordered a set of the pre-cat and post-cat sensors from an eBay seller located in Brisbane, QLD on 31st January and got delivery 1st February.
3 of these sensors were manufactured in Japan. As advertised, one of the post cat sensors was manufactured in the USA and branded DENSO First Fit.
I also located previously purchased pre-cat [air-fuel] sensors that were also branded DENSO First Fit. These were the ones that I fitted plus both of the post-cat sensors.
The replaced sensors have been retained and will get a good clean, eventually.
The problem I had with my 2009 200 series with it not changing up to 5th or 6th gear ended up being an easy fix late last year. To go back to beginning - 8 months prior to the start of the problem, I had the intake manifold cleaned by a diesel performance company and they talked me into having an EGR blank plate installed and adjust the ECU accordingly, which I agreed to while I was there. Then 8 months later it started to intermittently not go past 4th gear. The company said this issue had nothing at all to do with what they had done with the EGR. The problem got worse over a period of 12 months and it became a permanent 4 speed gearbox. After taking the car to numerous other places without success I ended up back at the original company who had by then come up with a solution. They said it was basically in a type of limp mode, so they did a minor remap of the ECU of some sort and I think they turned off the EGR valve. Probably not legal but anyway. If I hadn't done the blank plate 2 years ago it would've saved me a lot of trouble. It's all good now though.
