Lexus LS 2007+ :: Power Steering Feels Hard On LS460
May 11, 2014
I have purchased LS 460, 2010 with 21000 miles on it. Dealer said he put new Kumho tires on it. But the power steering feels hard, and is not even as soft as my Honda Pilot 2009. I have made an appointment with Lexus dealership for this concern ( I had the vehicle checked by Lexus store before purchasing.) I have read good reviews about Michelin tires, am wondering perhaps I need better quality tires. Do not know what the dealer is going to recommend.

Got in my 2007 LS460 and it wouldn't start. No power, no clicking, nothing. I checked the battery terminals and noticed they has some corrosion so I cleaned them and reattached. Nothing. I found that if I jiggled the positive cable the power would light up my dashboard with every light / radio, but it still wouldn't start....and I had to disconnect the cable in order to turn the power off. I had the car towed to a trusted Toyota/Lexus repair shop I've used for 15 years. They connected the cables to the battery and it started right up....but the power steering is out. They tried multiple things to get it working with no success. The only option now is to replace the electronic power steering unit.

So I recently purchased a 2007 LS460 with 115k on it. I've noticed that about a month ago the car started driving pretty weird. The transmission would shift hard and jerky almost through the first 3 gears, like driving a manual.
Also, when I tried to floor the car from maybe 40-50mph, the rpm would shoot up only 500 then downshift and accelerate causing a violent jerk. It feels like if I was driving at 50mph on 8th gear, when I floored it the car would feel like it downshifted to 7th gear for merely less than a second and downshifted again to 4th gear causing the car to jerk hard.
This is the car's history:
- Reset the ECU by disconnecting the battery (no luck)
- Auto transmission software has been updated at the dealer
- Valve springs recall has been completed
- Head covers has been changed
- Engine module has been reprogrammed by the dealer at 70k miles
- Trans fluid has been changed at 70k miles according to lexus.com service record
So at this point I really don't know what could cause this problem anymore, maybe it could be the transmission fluid?

Today my car came back from service, now when I reverse park I get this display where when you move the steering wheel you can choose the spot you park in. Before I was just happy reverse parking my car myself and get a different display showing me the back view with with green and red lines I think where the car is moving towards etc. I can't figure out how to disable this steering wheel park assist.

In the last two days I've noticed that my steering wheel would suddenly have intermittent episodes of being hard to turn for a second or so. It has gotten progressively worse over the last 24 hours or so where when trying to make a right turn the steering wheel feels noticeably "heavy" during the turn. And in some cases after I make a turn onto a side street I let go of the steering wheel for it to straighten itself out so I can continue straight down the street I just turned on but the steering wheel doesn't straighten itself out quickly enough like it used to and I have to physically turn it back myself otherwise I'd start making a u-turn motion and careen into a parked car. Weird.
I can only conclude that there's something wrong with my power steering rack.
FYI, I have a 2009 460 SWB AWD with about 78k miles on it.

2009 LS460 I have had my car at the dealer a few times for loss of power on acceleration. The last visit which lasted three weeks finally gave a diagnoses. The problem was confirmed by the dealer and the factory reps, a knock sensor picks up a signal that retards the timing resulting in no power, I was nearly run over by a semi the last time it happened. They tried to give me my car back on 7/24/14 with the knowledge that the problem is not fixable at this time but I should drive the car and they will tell me when there is a fix. I left the car at the dealer. I was also told that they had a few others with the same problem that could not be fixed.

I have a 2007 LS 460 with about 50,000 miles. Some 18 months ago, at about 35,000 miles,right after a service, I began to experience hesitation/lack of power when accelerating from a stop. Lexus fixed this by doing a software update to the transmission.
All was well till last month, when again right after a service, the car hesitated and totally lacked power , most noticeable from a rolling stop. Revs would very gradually climb to 5,000, with foot flat on accelerator, yet car barely moving. Once speed built up to highway speeds, car reacted normally. Took it back to Park Place Lexus who held the car for 10 days and did a major job changing the cylinder head, I think per L-SB-0033-08.
A month later, the hesitation/lack of power is even worse then before! I suspect the issue is the transmission, and the big surgery on the engine done last month was not required. After nearly being hit trying to merge with traffic today, the vehicle is back at the dealership, and I took their head tech for a drive. He experienced the problem, but did not venture a solution. He told me they take instructions on what to do directly from Lexus.

I have a 2010 Lexus Es350, and I am having this issue:
When accelerating hard, the car will aggressively drift to the right. During normal driving it is otherwise fine.
When braking from 60-70mph, I will also get a significant vibration in the steering wheel.
What can be the issue here? I've read possible brake rotor, tire out of balance, alignment?
Are these 2 issues connected?

So I found an 03 gx one owner and only 56k Miles on it. Nice truck. I noticed right away that the rear suspension feels hard and bouncy. When I adjust the height it does work but seems to take a bit. In the Low setting feels like it is on the bump stops. Not sure where to start, sounds like the level sensors can be an issue, so I will have a look at them. Feels like it is just going to the top height to me thus making the ride really stiff. I climbed onto the rear bumper and tried to bounce the truck and it is like a rock. Like the bags are over inflated.

I have tested 07 UL package a while ago, really liked the car, how it drives, really quiet, very smooth, good acceleration, very comfy etc. the only concern for me is it spacious enough ? I'm driving around 90% in town, how is it on a long trips with 2 - 4 people.... ?
Immediately after I parked ES 350, I have tried LS460 07 AWD, somehow it felt under power for me, maybe cuz it's a awd.. ES was faster in my opinion. It had it 100k miles on it, the car felt really solid like a rock, safer, but slower. Maybe a RWD would feel differently.
My plan is keep the car for 5 years or so, I'm also concern about maintenance costs too. As today I'm pretty much can get a LS 460 07 or ES 350 UL 10-12' for the same price.

I took it in to Charles barker Lexus (our dealer here) and they said the water pump was leaking, the front struts were totally blown out, and the 2 belt tensioners had some free play.
Got the dealership I purchased from to pay for the water pump but they would not cover the struts because they said the car pass inspection so they don't believe they are damaged.
Got and independent shop to replace the front struts with kyb 551122 for $400 parts and labor. While they were under the car they said the upper and lower control arms looked newer as if they were replaced recently
Got all wheels balanced at a little small used tire shop small change. The vibration that started at 60mph now starts at 65. Question is are all tire balancers created equally?

I have an 07 Camry with a hard to turn steering wheel. I had to replace the high pressure hose from the rack due to a leak. After that I basically bled the system as one would do under normal circumstances. With the cars front wheels off the ground I turned the wheel hard left and right. The wheel did give a bit but not to the point of perfection. After many turns I put the vehicle on the ground and repeated the process. The fluid no longer leaked but the stiffness was still there.
The hose was replaced at 110,000 miles. It's currently at 112,000 miles

I purchased my first Lexus in October, a very clean 2009 ls460. In colder weather (for Tucson AZ) in the 30's to 40's I notice that the transmission slips while the car is accelerating between 2nd and third gear.
By slipping, I mean as the car shifts between 2nd and 3rd it feels like it goes into neutral for a half second, so rpms spike 500 rpm, the car stops accellerating, and then catches as the next gear is finally engaged.
It does this pretty much every day when the car has been sitting overnight on the first steady acceleration after backing out of the garage. It only does it once, subsequent shifts a re pretty much normal.
Every once in a while coming out of a parking lot after say grocery shopping, it will do it again, just once.
I dropped it at the dealer and they of course could not replicate it.
I made a youtube video which shows it sort of. besides the rise in engine rpm, you feel a lurch in the acceleration as it drops down into gear.
Service records showed the trans was serviced just before I bought it.

My wife has a 2007 LS460. Some dummy at a big box store tied down the trunk to get a chair home by threading rope through the latch mechanism. Needless to say, the trunk will not close. Not with the button or manually. I tried the disconnect battery thing. Nothing. The lid goes all the way down.

Our 2007 LS 460 (98k miles) drives like a dream except from about 75-85 mph we have a general vibration. Its most evident in the steering wheel but everything in the car has a general vibration. It may have been there for a few months now, but I felt it when I drove it yesterday. There is absolutely no vibration below 75 and none above 85 (I was cruising at 90 mph and the car was solid). I tried to do some investigating:
Tires: Appear to be fine in regards to wear and the tire pressure is about the same in all of them in the mid 30 s. Alignment is fine and the car does not pull to any side.
Brakes: New brake pads about 10k miles ago at dealership and work absolutely fine.
Transmission / engine (I hope not): The car is 7th gear at that speed but it usually is anytime above 50 mph so its quite odd. We don't lose power and no lights are set off.
Body work / damage: doesn't appear to be anything on the front or sides of the car that cause this.

I've been waiting for to trade in my 04 Acura TL and move up drastically to either a 2010 GS450H or 2010 LS460 Sport. Both are driving me crazy because I absolutely love the look of both cars and the more I keep looking at the wheel photos makes it even harder.
I have 3 kids but 2 of which are older so size doesn't matter. I do prefer the GS due to the super sleek looking and 20" are a win BUT the LS on 22" with the air ride and data controller is a super win!!! not to mention the 19 speakers are better then the 14.
I know that I have to drive each car and I have not yet. Also pricing is pretty close for each car and it looks like the gas mileage is also pretty darn close so I don't believe that is an issue either way unless I'm wrong??
