Lexus RX 2010-15 :: RX450h Running Sluggish - Car Doesn't Seem To Get Up To Speed Quickly
Jun 10, 2015
I noticed recently that my car has been running a little sluggish lately and can't figure out why. What I mean by sluggish is that when I press the gas the car is relatively slow to get up to speed. Getting onto the freeway for example, or just trying to take off "quickly" (it's a Hybrid so not trying to race anyone) just not noticing the car doesn't seem to get up to speed as quickly as before.
This is with ECO mode on or off, just more noticeable with it on. Just got the oil changed this morning, still noticing it.
The car has only about 35K on it so really puzzled as to what might be causing this problem.

My 2004 Touareg V10 TDI drives like something's not just quite right, although hard for me to put my finger on. Essentially it feels sluggish, like it doesn't downshift to accelerate as quickly as it should, and like the automatic shifting is slightly jerky. This stuff is all even more noticeable at slower speeds and going up hill, but I think it's true even on city streets.
It's happened a few times, going up a fairly steep hill, that it seems to lose power and I can't get it over 20 or 25 mph even flooring it. Then when I turn the vehicle off and then back on, it can go more or less like normal again. Still, "normal" feels to me like something less than it used to be. I've recently changed the oil and all the filters (air, oil, fuel).
The dealer's service department says they can't find anything and the computer is not giving any error codes, but I know that it's not driving right.

Just wondering if there is any difference between the RX350 and RX450h wheels. Given that the RX450h is a hybrid, the wheels should be lighter for better fuel performance.

I just bought a ceritifed pre-owned 2010 RX 450h. I love it, but a couple of questions as I get to know the car.
1) The rain sensor seems to not work. I set the wipers to what on another car would be "intermittent" but the wipers never come on. Am I missing something, am I a dummy? Or should I just get the dealer to replace the sensor?
2) Any way to turn off the seatbelt warning chime?

It almost sounds like somebody is taking a small hammer and banging at the plastic cover on top the engine when the vehicle is started new from cold. After about 8 or 9 knocks it goes away.
Taking it to a dealer soon to get it checked.
2010 Model year. 81k miles.

I just bought a certified 2011 RX 450h and my sirius keeps going back and forth to no signal for no reason. I've had sirius for 9 years in other cars and it's never had this bad of reception. It's at the dealer now but the loaner 2013 RX350 they gave me does the same thing. None of my other cars perform this way on these same roads. Had this poor reception problem, what has been done to remedy?

I dropped off my 2015 RX450h at the dealership yesterday because the rain sensing wipers no longer sensed rain. Late in the afternoon the service writer called and told me that they ordered a new windshield because the sensor is part of the windshield?
Sounds strange. I've heard that some aftermarket windshields were interfering with sensor's ability to sense but never an OEM windshield.

I test drove a 2013 RX450h this morning and almost decided to purchase it. The one problem I experienced was a dark area, about 1/3 of the nav screen on the driver's side with my sunglasses on. Taking the glasses off eliminated the problem. I tried a different pair of sunglasses and was able to duplicate the dark area. I am assuming this problem is caused by polarized lenses. I do not have the problem with my 2010 LS nor the 2013 GS350 I also tested.

My less than 7000 miles RX started making noise when I pushed the brake pedal. Evidently it sounded like the "LS brake squawk" according to service foreman. Not sure if the actuator is same in all RXs.

I brought our 2010 Rx450h to the dealership several months ago due to an occasional clicking noise in the upper steering column, behind the steering wheel area. The repetitive clicking was most noticeable at slower speeds while turning the steering wheel.
The dealership had the car for about 3 days saying it was a loose cable and then told me when I picked up the car, that sound was the way it was supposed to be, part of the electric assist steering. So the clicking noise continued.
Now the steering is getting stiffer. Some days much stiffer. This happens more when turning the wheel slowly.

I bought replacement blades for Drivers side and rear window.
I'm half-way mechanical... OK , maybe 1/4. It appears that the blades themselves are not replaceable; only the refill (squeegee) portion is. is this correct?
Front-drivers-side actually looks like the complete blade may come off, but it's not obvious how it releases.
The rear appears to have no way to easily remove the complete blade.

I have found that when I accelerate quickly, while entering the expressway or getting around a semi for example, a burning smell enters the car. I imagine it's oil but uncertain. The smell occurs shortly after the quick acceleration and it doesn't occur consistently.

I have a 2010 RX350. Using my iPhone 5 with the bluetooth in the car is a little hit and miss/sluggish. When hitting the button for Siri, the car seems to struggle with the process.
I am curious if the firmware for the car is current... and if not, does a more current firmware update the bluetooth for better functionality. I haven't had it updated for almost 2 years. I do have navigation.

In my current speedometer the speed needle doesn't work i did everything and changed all sensors and checked all related issues and all is fine turned out the issue was with the speed gauge it self. So i bought my self a used speedometer.
Now my question is, how to dismantle the speedometer cause I want to take out the speed gauge from my old one a replace it with the new one i know its much easy to change the whole thing but I don't want to play with the mileage I have on my car.

I drive a 2009 GS350 and I just noticed that when I start the car and decide to get out while it is running my Key FOB doesn't perform any of the functions suck as lock the doors or open the trunk. I wasn't sure if it was supposed to do this as when I leave my car running to warm up for a few minutes I kind of want to lock the doors.

2010 Lexus Rx450h... Rattles in the morning, only when really cold. (Around freezing?). Somewhere in or near the passenger side door, or the air vent by that door. It gets quiet(er) after warmup. Car has been at the dealer for a week... They can't find it; they want to pack in additional insulation. That hardly sounds like a sound solution.

So with the car cold or hot . I turn the ac on and the motor rpm drops quickly and compressor kicks on . Can confirm this with someone watching with hood open. Low speed on both fans not working
Of I let the car idle in the for about 15 min then both fans high speed will kick on and run for a short time. Temp guage will always stay around 190. Car never overheats even in 95deg weather.
I tested the fans by jumping the 3 pin connector off the radiator and according to that test it's just the resistors on the low speed. So I ordered the nime control module.

I have 2008 VR6 4 motion wagon with about 98K miles. It has been relatively trouble free and I love the car. To try and make it last I am trying to stay on top of maintenance. I had a VW warranty until 72K and got several things fixed along the way. But, I had asked about the one weird thing it does well before it went out of warranty to no avail ("no trouble found").
The weird thing is that sometimes it sort of stutters when I slow down from a high rate of speed quickly, like exiting a freeway. I described it to my new mechanic (no longer beholden to the dealership mechanics) when I was speculating a new transmission might be in order at some point and he said it was probably an issue with the program that tells the transmission when to downshift and to ask about a software update. I did; none available.
Is it firmware related, how to get it fixed?
