My new LS460 AWD 2008 is jerking on 60-80KPH(37-50)MPH, when you driving without any acceleration.
I have only 900km on odometer. And it's started jerking from 0. I gave my to Lexus for a test. They tested it over 7 days, and now they are saying nothing is wrong with it. And it's normal for AWD version.( WHAT???? )
They have one more new AWD 2008 and it has the same jerking issue.
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.
View 14 RepliesMy LS 460 has a pulsing wheel/front end noise that seems to increase as the speed increases from 5 mph to about 30mph and then fades out. I brought it in for service and they test drove it twice with 1 and then 2 service techs. They could hear the noise and said to me that they think it is cupping on the tires. The tires are in great condition inside to outside.Tires have only 14000 K. I switched the back to the front. The same dut-dut-dut-dut sound increases as the speed increases to about 30mph.
I believe that the noise is something more serious. I noticed that when the suspension compresses over a high point in the road at say 20mph the sound will stop during the time the car is comming of the high point in the road. Could this be a bearing/suspention- or something with the breaking motor because I also have been using the break hold feature for several months and not sure if that could cause harm. Also I do hear more grind or grumbling when turning the wheel to the left at low speed then when turning to the right.
Since we purchased the car we've been having problems with the transmission or acceleration, when the car is shifting from park to drive engine speed RPM goes up and it is difficult to stop the car from driving. The dealer does not know what to do and the factory support is useless.
View 14 RepliesWhen I drive my car ls460 , ABS & VSC and traction light coming on the board, sometime disappear and after 3 or 5 days coming on the board again .
I check by the computer, I found this code C1253 which mean (pump motor relay). What is this code or the location in the car.
I used to have a GS300 and just recently traded in for an 07 CPO LS460 SWB, Mercury Metallic with light gray interior. Love the car, big difference in quality of material and build. Anyways, I noticed that the hood and front fenders get really hot to touch after driving. It seems to be hotter than all my other cars. The coolant gauge in the instrument panel stays in the middle and does not show over heating. The hood stays hot and takes quite a while to cool to ambient temperature. Is it attributed to the engine compartment covered both top and bottom (for aerodynamic reason), which may delay air flow and cooling?
Recently Car and Driver had an article regarding brake overheating in Nissan 370Z Nismo, under harsh repeated braking. The brake fluid would boil and loose vacuum. After analysis, the suspicion was that in the zeal to improve aerodynamics, the engineers did not design adequate brake cooling. I'm wondering if Lexus engineers, in pursuit of aerodynamics, may have compromised the cooling and airflow through the engine bay. Like I said, there are no indications of the engine overheating, just the hood getting pretty hot after even a short drive. Most likely, I'm just paranoid and my OCD is kicking in.
My 2009 LS460 AWD with air suspension now, at 56,000 miles, has this noise frequently during driving and sometimes at idle.
Like an air compressor for a few seconds. It's not loud, but you definitely hear the whine/air type noise. It's almost not even bothersome for me as I've gotten used to it. But when my wife or others are in the car they always ask "what is that"
Having problems with total car vibration, especially after the car sits for awhile? I am told this is normal, because of the type of tires on the car.After five returns to the dealer, Lexus replaced them and the car still shakes when driving?
View 14 RepliesI have a 2007 LS 460 with active cruise and lane keep assist (LKA). All works fine during daylight hours but if I drive at night I get the yellow Fault Triangle together with pcs warning and instruction to have system checked by the dealer. The dealer says that there are no fault codes showing on the diagnostic system.
View 6 RepliesMy problem is this: if I accelerate quickly (either flooring it or close to it), then once I reach about 55-65mph the car suddenly jerks horribly. Sometimes it's one big jerk, other times it's several small jerking movements. ECO transmission ...
It's not a problem at speeds under 50mph, but it seems once I cross that 50-55mph threshold, I can't put my foot all the way down or I will get the jerking. It will also occur if I'm going say, 60mph and need to quickly get to 75-80mph. The first time this happened, I was accelerating onto a highway and the car jerked so badly that I thought I had gotten rear-ended.
I have a 2007 2.0T and about two weeks ago the car started jerking while accelerating. It only does it when the engine is cold. Sometimes it does it more than others. Shortly after the engine reaches its normal operating temperature, it stops jerking.
I scanned the computer with my VAG-COM but there are not DTCs. I originally suspected the oxygen sensor but the jerking happens even before the oxygen sensor kicks in. So even when is running a fuel rich mixture prior to getting feedback from the O2 sensor it jerks sometimes.
I have just under 55K miles, so I am not sure about the spark plugs but I find it strange that once the car warms up it stops doing it. The cam follower got replaced about 12K miles ago. The air filter is due for change soon but I don't think that is the problem, last time I looked at it (about 3K miles ago, it didn't look that dirty). I need to check this one again...haven't had time lately.
The only thing that was done recently to the car was the replacement of the transmission valve body under the powertrain warranty. The first few days everything worked okay but then a few days after the repair the jerking started. Could this be a symptom of tranny issues?
I have a 2002 camry with 212000 miles on it and just lately when driving at a constant speed 60 mph or over it starts to buck or jerk a little bit and you can feel it in the seat. I've had the throttle body cleaned and put in a new mass air flow sensor and it hasn't fixed it yet. What might be causing this? It doesn't do it when accelerating or slowing down.
View 9 RepliesI just got a used GS350. At about 20-25mph, it can sometime hesitate/jerk when I am driving without much acceleration. If I press the accelerator hard, the car accelerates without much problem.
I tried searching through the forum but couldn't find same problem except maybe the LS460 [URL] ....
I have tried cleaning the MAF with CRC cleaner + resetting the ECU by unplugging the battery for 10minutes but I still have the problem. Strangely, I didn't have to recalibrate the windows after plugging out the battery, but the GPS did the long initial boot-up..
I drive 07'es350 and I have felt jerks while driving usually when accelerating or slowing down from speed. Did check with dealer before for transmission after analysis by technician he said it is perfect, recently read on internet and saw fuel filter can be an issue but when called the dealer he said filter is in gas tank and it is lifelong. Not sure what kind of diagnosis I should do to find the issue.

View 7 RepliesI 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 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.
View 14 RepliesOur 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??
