Try making a youtube video and/or talking to your local news. This and the excessive noise and vibration threads are the two most popular threads on the 4RX forum. Surprised it hasn't gotten Lexus' attention yet.

 

Well since there is a TSB for the hesitation and vibration it seems Lexus knows about the issues.

And why would local news be interested in something like drivability and noise/vibration. It's not faulty, it's a design issue for the vibration and the hesitation is purely the software written for fuel economy.

 

Do they though? Feels like half the posts say that the TSB doesn't work. Local news can at least shine a light on the issue. More attention doesn't hurt. Anyway it doesn't affect me either way, except when I drive the loaners.

 

"half the posts", I'd say some and many of them have come back on here and said what I did, that the dealer hadn't reset the system.
These issues only affect some cars, our Japanese made ones are very good, hesitation is there but that's by design, the vibration is only felt in mine when you think about it and know it's there...very mild.

 

Why do you keep saying that the hesitation is there by design? If you press the gas pedal, shouldn't the car respond?

 

The mapping software of the transmission is written for fuel economy, if you want more/better response you use Sport mode.

The TSB that was issued is only used on vehicles where the customer has complained about the apparent lack of power.

I notice the hesitation in busy conditions but in lower speed, less busy conditions where I'm happy to drive gently the hesitation is not apparent. Many people would drive like that all the time, it's a luxury SUV not a sports car, so may not even be aware of the hesitation.

 

If the same phenomenon exists on every unit, it's not an accident.

 

I should add that when I say by design I didn't mean Lexus wanted it to hesitate, I mean it's as a result of the software. It's not a fault, it's not broken it's just how Lexus has made it so fuel economy is better.

 

Yes it does respond...eventually. For instant response one has to put it in sport mode.
This pursuit of MPG is ruining all the driving pleasure that we used to get from our cars, aided and abetted by those looking for "connectivity" rather than road-holdinng capabilities is turning our cars into appliances.

 

Trading for a Volvo T6 is always an option. The T6 is turbocharged like the T5, and supercharged specifically to eliminate lag. Of course, then you have to live with the Volvo....

 

I've always wondered how long would THAT engine last.

 

I can speak for myself only, but i don't have alot of hesitation, but also the fuel economy is not good either. I drive in Eco mode most days.

If i want fun Sport+😀😀

 

And I bet you drive gently usually?
Is the area you drive around flat or hilly?

 

If I am reading this correctly, you are saying that Lexus unintentionally created hesitation as a result of pursuing MPG gains, therefore it is not a fault and it's not broken? If it was unintentional, how could it not be a fault?

With the 450h, there is no hesitation at all and the 450h was geared toward fuel economy.

 

This is like saying every security vulnerability found on any device is not an accident...

Just because it exists on every unit does not mean it is not a mistake.
