Lexus LS 2007+ :: Loss Of Power On Acceleration - 2009 LS460
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 owned this car for six months. The car now has 39K. The problem is getting worse.
Re: Lexus 2011 LS460 AWD
Subject: Hesitation / momentary loss of power when accelerating after turn.
When accelerating after a sharp turn with light to moderate acceleration, the car will have a momentary loss of power for about 1, 2, or even 3 seconds. This does not happen often, but perhaps once every two weeks and I cannot replicate the problem despite attempting to do so.
In all cases, I am talking about DRY pavement. It always happens after a sharp turn usually to the right. (Probably because most sharp turns are to the right actually it only happened once on a left turn that I will describe below.) Acceleration is light to moderate NOT hard acceleration.
In one case it caused a serious situation. I had just purchased gas and was entering a busy freeway. When accelerating, the engine had a total loss of power for a couple seconds as a large semi truck bore down on me with its air horns blaring.
I have a strong clue that may debug this problem. Once, when turning left, the car suffered a total loss of power. There was no traffic and I kept my foot lightly on the throttle. The car remained unresponsive. The engine did not stop, but it did not respond and remained this way for at least 5 seconds until I took my foot off the accelerator and then back on to the accelerator. During this period of suspended throttle, I noticed that on the right side of the dash an orange alert symbol was flashing I think it was a swerving car? I assume this indicated that the car was losing traction and the computer decided to cut power until traction was regained. But the pavement was dry, and the acceleration was normal. In no case did I ever sense that one of the wheels was slipping.
Lexus LS 2007+ :: Engine Dies / Intermittent Electrical Loss And Then Power Resumes
I have a 2007 LS460 L. It has recently started losing electrical power in fraction of a second intervals. The map data sometimes works or displays an error on the screen. The radio has been functioning but now is also starting to flash off intermittently. Now when this happens it feels like the engine dies and ALL electrical is off and then power resumes. This affects steering, engine power and brakes. My wife drives this car and loved it until now.

RX350 AWD 2007 ...
I recently starting hearing a beeping noise coming from the inside of my car and then i noticed the traction control symbol on my dash. I looked up the symbol in my manual and found it to be the traction control. However, I am not sliding when this is happening. I am just going around a corner, or in 1 case just merging on the highway. I have had this car for several years and it didn't operate this way, so something is definitely wrong.
One additional piece of information - My rack and pinion steering just got replaced in the last couple weeks. However, I called that shop and they told me the two are not related. I'm not sure, so I just thought I would add that piece of information in case it matters.
Lexus LS 2007+ :: Driver Seat Memory Does Not Work - Beep When Moved Back
So this morning, I pressed memory seat #1, and it did not move my chair to the position that I set it for. I had to adjust the chair manually. Every time, I move the chair back or recline the back, in intermittently beeped every 1-2 seconds. It does not beep if I move the chair forward. Could it be the fuse? or what could be wrong?

I own a 2000 7.3 6 speed with 175,000 miles. I just bought it less than a month ago and it is my first diesel.
About a week ago I stepped on the gas and it just had nothing. I have a TS 6 position chip that I unplugged as soon as I noticed the loss in power. When I first bought the truck it was incredibly fast and now it has nothing to it at all. I have to have it higher in the RPM's to go up hills (especially when its not warmed up). If I push the pedal down it will sound the same, boost will get to about 14 (without chip) and the truck doesn't let out any smoke but it just doesnt have any power at all. I recently towed another vehicle on a trailer and it really struggled with it, more than I thought a diesel should.
When the chip was in, the truck would let out black smoke even after I noticed the loss in power. That made me think that the engine was getting enough fuel. I thought there could be a boost leak somewhere but it still builds 14 psi. However, I do not feel boost kick in at all! When I first got the truck it would only build around 14-15 stock but it felt a hell of a lot faster and I could feel when boost would really kick in. I took off my intake and looked at the turbo and the fins are in great shape and there is little to no play.
What the problem could be? I don't have very much money to start dumping parts into the truck and Im not sure what to do. I guess my questions would be:
1) Is it a boost leak, fuel problem, or something else?
2) Could a gelled filter give me these problems?
3) What should I do and where should I start?
Lexus RX 2010-15 :: Power Hatch Not Working - Won't Open Or Close Just One Long Beep
Power hatch stop working? I get a long beep and nothing. Won't open or close, it has to be done manually. My next oil change is in 1-2 months so I was going to have it looked at then by Lexus under warranty. Nothing seems stuck in the latch.

I have an 07 6.0 with 400,000 miles. Has been a great truck with no major problems. Before I started the work I had 3 bad injectors, running rough and the oil/ coolant temp just outside of 15 degrees. So I tour her down and replaced head gaskets, installed arp studs,all new injectors,all new glow plugs and new oil cooler. Ran great for a couple days. Then when driving to work lost power on and off for a few miles then completely gone could only go 10 miles an hour. I checked codes and there was the under boost code witch has been on there for a while and I forget the other code but it was for the ipr valve so I replaced the valve and right after still the same but that code went away and the p0470 popped up. So I cleaned out the ep sensor tube and replaced the valve. After several miles she now runs great but now I'm getting a little puff of white smoke when I take off and not every time and mainly when I take off some what quick. All codes are gone expect the under boost. I have an egr delete already.

I have a 2007 F350 6.0 Diesel. Truck starts and runs great for about 10 miles and then loses power and slows down til it dies, it does this without any kind of warning and does not rattle or anything. If i let it sit for about 15 min it will start right up and drive fine for another 10 miles or so and do the same thing.
It did the same thing in December but would not restart at all and the ficm was the cause at that time so i went ahead and replaced the ficm just to eliminate it. I also replaced the fuel pump and the ipr and icp valves are good. The only engine code has to do with the fuel level sensor and that has been on for a year. The egr was recently replaced, the hpop is putting out the psi that it is supposed to and there are not any internal air leaks.
Lexus RX 2010-15 :: Tailgate Made Single Beep And Did Not Open When Push Power Button
I noticed yesterday that when I push the power tailgate button on the dash to open it, it made a single beep and didn't open. I could only get it to open the tailgate after I unlocked the doors. I also noticed that the key fob wouldn't open the tailgate from outside the vehicle while the doors were locked. I never noticed this before. Is this normal?

I have a 2010 LS460L AWD with the OEM wheels. Periodically, one or two of my tires experience slow PSI drops. The Firestone Auto Center attributes the tire pressure loss to wheel corrosion where the tire bead meets the wheel. After the Auto Center cleans the wheel, the tire pressure holds. However, the problem recurs periodically. It is not isolated to one wheel...

I'm not sure whether it's real or even possible. Starting this summer, when it's hot and I turn on AC, I feel loss of power from the engine. When need for speed, it's slow to accelerate. The engine is less powerful than when it's cool and no AC running. Is this possible? It's 2010 V6 AWD.

View 3 RepliesPrius (2004-09) :: 2007 - Total Loss Of Power?
I drive a 2007 Prius, I just purchased it about four months ago. Today after filling up with gas I drove about 60 miles and suddenly three lights on my dash came on. The all system light (the red triangle), the check engine light as well as the VSC or VCS what ever way it goes, my electric batter was also low on charge having only one bar(my car is not a plug in, the battery is recharged by the engine) then the car lost all boost and while pressing on the gas it was not accelerating. I pulled over and put it in park so the battery could charge. It charged to half way, however the lights stayed on.
My car then started running really rough, I am still in park at this time. I put some gas stabilizer in my tank because I thought maybe I got some bad gas. I left my car sit for about five minutes before turning it back on. All the lights were off except my check engine and my car started running normal. Then about three minutes later all the lights came back on and the car started running jerky again. When I push the gas to move I can, however I've only gone about four feet because it is running so rough.
Santa Fe (CM - 2007-12) :: 2009 - Momentary Power Loss While Driving
The car started rough idling and a few weeks ago while driving "lost power" momentarily. I went to take a look at it and even just idling it will randomly drop 1000 rpm, or when the gas is one in P it does the same thing. also the dash lights dim at the same time.
I pulled these codes (below). I cleared the codes and tried to replicate with no luck. The car had been sitting in a parking lot outside for a few days and it has been -15C. I asked if it seemed to only happen when it was warm (the week before it was +10C) and they said yes. It has been another week (still cold) and the codes have not returned.
Quick google of these codes suggests maybe a throttle position sensor and/or loose battery connection.
Santa Fe (CM - 2007-12) :: Power Loss Suddenly When Driving On Highway At About 80-90 Kms/hr
I am using a Hyundai Santa Fe (Petrol, 2011 Model) here in Saudi Arabia. On July 17 (11:30 pm), I was driving in a highway at about 80-90 kms/hr when suddenly my vehicle lost power (steering wheel, brake, etc).
Baed on the diagnosis of our company mechanic, it was an alternator problem. He said the alternator bearing got stuck up.
Prior to this incident, on July 7, the same vehicle got stalled twice while it's parked. In the first case, I was able to use it after jumpstarting. In the second case in the same day (4 hours after the first case), jump starting didn't work so they have to replace it with a temporary used battery. I noticed that I had a hard start (the engine responds only after 3-4 key ignition). After replacing the battery with new one, I was able to drive normally from July 9 to Jul 17, and then the incident happened as I described in the first paragraph.
Question: Is there a way to detect the alternator bearing problem before it actually breaks down? If there is, what procedure or predictive test is normally followed to identify potential problems in an alternator?
Sonata NF (2006-10) :: 2007 - Occasional Power Steering Loss
My daughter's 2007 Sonata 4 cyl (88k miles) has an occasional power steering loss. It has only been noticed right after slowing down from highway speed. Total loss for a few seconds then comes back. No dash lights or noises, just steers like an old classic without power steering - then can.
This is kind or a repeat post from another individual but he had a V6.
SBR711 recommended replacing the Harmonic balancer and I am inclined to do so but parts guy at Hyundai said that typically is not an issue in the 4 cyl model. So he does not keep item on hand.
Fluid is fine, clean and proper level. No screeching etc..
Santa Fe (CM - 2007-12) :: Oil Light Came On - Immediate Loss Of Power Braking And Steering
Driving 30 mph, oil light came on, immediate loss of power braking and steering. Engine did not stop, oil light disappeared yet still had loss of power steering and brakes. Still in D. Policeman had to stand on brake pedal to get into Park so that engine could be turned off. Towed to dealer in next state and dealer said cannot replicate so cannot fix.
Car is 2012 Santa Fe w/ less than 6,000 miles on it.
Santa Fe (CM - 2007-12) :: Loss Of Power/ Increased Fuel Consumption
What's happening with my Santa Fe (3.5L AWD). In the past couple of weeks I'm seeing poorer fuel economy (about 15% worse) and the vehicle feels like it is down on power, especially in fifth gear. I mean, the vehicle works and some might not notice, but... There are no warning lights. Engine oil is slightly high (1/4 inch or less) and transmission oil appears to be correctly filled. Don't see leaks from this vehicle on the driveway.
I had an oil change about 3 weeks ago, at a Hyundai dealership, where I switched from regular to synthetic. I was told that no special procedure was required in making that switch, so none was done. About two weeks ago, the stereo system was dead one day. Would not turn on at all. In trying to troubleshoot I pulled the Audio and Radio fuses (there seemed to be three in the dash area), but they were fine and after I reinstalled them the radio worked again. Those are the only maintenance and other issues I've seen in months.
The vehicle has pretty new rear brakes and I don't feel unusual heat there. Could the switch over in oil types or electrical issue with the radio be related? I've done many hundreds of miles since both events.
