Lexus RC 2015+ :: Transmission Sound Particularly Noticeable On RC350
Jan 12, 2016
So ever since I got my RC 350 my transmission wind has been particularly noticeable. I got the luxury package btw. Wondering if this is normal or if I should contact the dealer about it.

I noticed that the RC was blowing out a lot of white smoke from the exhaust. I peeked underneath the car and i hear what it sounds like droplets of water falling down. and then i go inside the car and i see an engine light(yellow triangle). I honestly don't know what it could be wrong right now.
The car only has 12k Miles.
Here is the video......

Have problems getting window tinted? Just got my RC 350 and i took it to one of the most referred places in town for tints. (small town)
Anyways, they are having trouble with the drivers side window bc that little autoroll down feature when you open the door keeps on messing up the bottom edge of the tint. I've already taken it back to the shop for them to fix it and now I have to take it back on Monday to get it fixed again.
Any way to disable this auto roll down feature on the rc 350?

I've been trying to trace a whirring sound since purchasing my 2010 RX350 this summer. I've tried two sets of Michelin tires, Primacy and Latitude HP, which I thought was the source of my sound.
But what are the chances of two sets of tires making the exact same sound
The sound is most noticeable between 30 and 40 mph on smooth roads and is like a "playing card against bicycle spokes' only much softer (if you are old enough to remember that).
Currently I'm thinking gear mesh noise from the front transfer case or maybe there is a sensor for the anti-lock brakes or traction control that reads a toothed 'gear' for measuring tire speeds that may be mis-adjusted.

Our temps have hit into the -18 to -25 Celsius... I have noticed that on 3 different occasions now that the truck feels like its locked in 4wd when I reverse out of my drive way.My Truck is an F250 Crewcab with 4800 miles
This all started with the cold weather. At first I thought my 2 yr old was turning switches on while he was up front one time, but it happended again the following morning taking my 5yr old to school...
I back up up about 20 feet and then make a fairly sharp 90 degree turn and then all the way down the driveway to the street...its really noticeably on the 90 degree turn..once I turn to go forward it still seems jerky...same as having 4wd engaged on dry surface while turning..
After a little bit of driving it seems to go away...also keep in my mind that the 4wd switch has never been touched at anytime at all...we have a lightly snow packed driveway but my traction is still fine to where 2 wd is all that's needed
Could it be something in the rear diff "catching and releasing" for lack of a better term ?
Locker issues, clutchpacks...?
As I am typing I also remembered making a right hand turn on dry pavement and it felt like the rear end slipped a bit and then caught again, much the same way it would fell as if you hat one tire on a small patch of ice and slipped as ya took off and then caught as it hit the dry pavement...

I have had JoeZ/PTS catback exhaust on my rc f for a few months. I recently put PPE headers on and when I rapidly accelerate in park/neutral I get a whistling sound especially when backing of the accelerator. What it is?

Several times it would have been nice just to pull the plastic grills off and clean out the bugs. What are the details on how you can do this?
Using a tube to vacuum tube through the grill holes can result in bending the fins. Attached is an example hack at a coin op on a road trip. Need a better way.

Having a fan like sound apparently coming from the gas tank, but different than what everybody is saying is the fuel pump- its not a whirring sound under the drivers seat and not while the engine is running. I have heard this a couple of times after the engine has been off a few hours of sitting in my garage, and then after a few minutes it goes away. The last time, I opened the fuel filler cap and the fan sound stopped immediately.

Not sure if this is a normal characteristics of our Fsport brakes, but when I am in reverse and I apply the brakes I hear a squealing sound. Is that normal? By the way my car just hit 20k miles

I have 2015 IS350 F sport. At 400 miles I started hearing this static sound which seems to come from the center or the driver side dashboard. I don't hear it if the car is not moving but as soon as I hit 5-10 mph and above, it becomes audible. I tried pressing the dashboard to see if there are loose areas but couldn't find one. Also, I thought they may be coming from the center speaker but the sound doesn't change whether the stereo is on or off. Of note, it is more audible along bumpy roads.

I bought a 2015 ES350 in August and have a couple of weird noises.
First is what sounds like either door rubber seal on body rubber seal or window on rubber seal noise over certain types of bumps. Is this common? I can live with this until I bring it in for its first service, but it might be a simple fix I can do.
The second is more of a concern. When I'm moving slowly over an angled surface like a driveway that might cause some "twist" of the car, there can be a loud pop sound. Since it does not happen very often, it is very difficult to locate, and I'm sure its one of those things the dealer service department will never hear. When it happened over the weekend, it almost sounded like it was coming from the roof. This morning, it sounded like it might have come from the rear driver side door, but it is hard to tell.

Been having loads of fun with my Excursion. I've completely gone through the rear axle, new Yukon 4.30 ring and pinion and "ALL" new Timken bearings. I set the pinion at 30 inch pounds preload. Back lash is 13 thousands. But now I have a gear whine during acceleration. Slight at first but more noticeable near 50mph. Coasting or decel is quite. But just barely touch the gas pedal and it starts to whine.
I know that the backlash spec is published as 6-10 but other sources state 12-15 thousands. So that's why it's set at 13. Gear pattern looked great to me. In fact most changes I tried had little effect. So is it just normal for a gear set to whine until broken in?? Should I reset the backlash down. I only have about 40 miles on it. But would like to fix before it's wrecks something.

2003 xle v6 auto... 105,000 approx... Seems to be developing a noise, which I hope is not the transaxle. It is a bit like a "whine" or "growling" sound, can't quite place it. Driving around at slower speeds with windows open, cannot really hear anything.
Up at 50 MPH or more it is noticeable and, unfortunately, seems to be getting louder. Does not seem to vary with speed. Don't think it is some weird wind noise.
I did do the poor man's trans flush about 6 months ago (drain pan, fill + 1 quart, disconnect hose, run a quart out, add quart, repeat until clean comes out) and it has been happy. Also did timing belt/idlers/wp a couple months ago. Did not see a way to change the diff. Seem to be a drain, but no fill, so I left it.
My suspects are - wheel bearing(s), cv/axle, transaxle. oh, tires, I guess.

The subject: F150, 2007, 5.4L, FX4 version. It has only 80K miles and was very light used by my sister. It seems to me come with a 4R75E ....
Recently I notice a strange vibration every time tranny downshift from 4 to 3, specially noticeable going uphill. Some times can be feel when tranny shift from 3 to 4th...
A friend in my town comment to us, this is a very common condition here because there are just small streets and avenues so that truck shift very frequently betwen 4 to 3 and then back to 4th...
Sounds like a excessive wear on a bearing thrust ??

I have 124,000 miles on my 2002 subaru impreza outback sport and this car runs very well and has been maintained well however the last couple weeks I have noticed a slight rattling sound toward the right front side of the car almost as if there were pebbles inside the wheel covers when the car is driven at low speed and I begin to accelerate. It also sounds as if the rattling could also be coming from the exhaust also as if it were loose fitting but the tailpipe is on the left looking from the rear of the car. Another possibility I thought of was the fender was loose or the tire was rubbing against the wheel well or something. It is one of those small annoying sounds that does not seem to warrant bringing in to a mechanic yet but I am curious about what that is.

I have the '03 Lincoln Aviator 4.6 DOHC. It has a noticeable knock/ping/chatter and somewhat sluggish acceleration. I notice the pcv hose was collapsed and shredded. I replaced the hose and valve, didn't change idle or acceleration and I still hear the hissing noise in the same region. I unplugged the egr valve and started the truck, the idle was the same as before I unplugged the valve. could a bad egr valve give a vacuum leak that is hard to detect? I tried testing for leaks by squirting starter fluid near the suspect areas, and I couldn't detect anything. Could a bad pcv valve be caused by a bad egr valve and/or vise versa?

I have a 2000 Suburban with about 170,000 miles on it. I'm getting an audible clicking sound at slow speeds which increases as the vehicle speeds up and also a fairly severe vibration which becomes noticeable at about 20 mph and becomes worse as the speed increases. I thought maybe driveshaft but things seem fairly tight. Also, this has gotten gradually worse over time.
Ok I figured out where the vibration was coming from...U joints in the front driveshaft are shot. Now I have another problem...I've removed the fwd u joint straps and according to the book, the driveshaft should simply slide to the rear into the transfer case so I can lower the fwd u joint but the problem is that the part of the shaft (which slides into and out of the transfer case) seems to be frozen/stuck. Do I simply beat on it with a hammer to break it loose or am I doing something wrong?

I have a chirping/ squeaking sound in the engine extremely noticeable on idle. It's not the actual belt because it continues the noise much after the car is heated up. Have no clue what it is, I have 145000 miles. Also when running the engine hard notice a hissing sound sort of like turbo at high rpms especially with ac on high.

have 2002 Explorer with 4.6l that stalled at a stop light and upon restart, there was noticeable ticking and a sucking sound. The exhaust regularly sucks your hand against the pipe. Ticking is from all around the engine. Exhaust smells like rotten eggs.
Son was driving and we just got it back to house so I do not know much more than that. Where to start to diagnose.
