IS F (2008-2014) :: Slight Hesitation When Start To Accelerate From A Stop
My isf for couple months now and love the car. I have an 08 which only 7k miles on it. Lets say at a stop I start to accelerate, I notice a slight hesitation before it picks up around 1-1.5 rpms. Under hard acceleration I don't notice it, but with nice and easy acceleration that slight hesitation is kinda annoying. Not sure since car has such low miles on it if I need to run fuel injection cleaner or something, of if something else could be wrong. I kinda mention it to the lexus service manager and he said something that next time I bring the car in that he'll let the mechanic do a tranny ecu update of some sort? I didn't know that there was such a thing.

RX 350 (mine is 2013) produce a slight bump in revs as you decelerate moderately going from 2nd gear to 1st? It goes away after the tranny is warmed up. Wondering if it's just a result of the cold weather.

IS F (2008-2014) :: Metallic Vibration Noise On Cold Start
Had my JoeZ exhaust installed at my first oil change at the dealership about a month ago.
Anyway, late last week I noticed on cold start in the morning I'm getting a metallic vibration noise. This is on gentle acceleration out of my subdivision. It disappears within a minute or less and doesn't re-occur until the next morning. Best way I can describe the sound is a cell phone set to vibrate sitting on an aluminum cookie sheet.
Any hints on what I can check that might be the culprit? I already checked to see if the muffler tips are hitting the exhaust diffusers but they're clearing and I can reach up around the canisters and fit my hand up around them so they're not touching that silver heat shield material.
IS F (2008-2014) :: Belt Slip Noise In Manual Mode Shifting Above 5.5k Rpm?
Car is:
1) Warmed up
2) At a standstill
3) In manual mode, 1st gear
4) Traction control is on/normal
5) Sport mode is on/off (doesn't seem to matter for this example)
How to verify:
1) Hit gas, more than 3/4 down
2) Shift above 5500rpm
3) As transmission up-shifts a drive belt squeal is heard.
4) Car otherwise accelerates normally.
This happens on two IS-Fs I've driven, a 2009 and a 2010, with or without the AC on. Is this a common issue? If so, what belt is slipping?
Ford F-150 (2004-2008) :: 2005 - Slip Or Grinding Noise When Go Up A Hill And It Downshifts Into 3rd Gear
Ok I have been trying to find out what is going on with my truck and I cant seem to find anything on here that points to all the symptoms I am having. I have a 05 xlt 4x4 with 5.4. For the last 5 months or so I have been noticing a slip or grinding noise when I go up a hill and it downshifts into I believe 3rd gear. It sounds like going over rumble strips on the road but only lasts a second. It also does it sometimes when I pull out from a stop.Also when I let off gas or brake to a stop it seems to shudder a bit.
Maybe its my imagination since I keep hearing for the grinding sound, I don't know anymore.Its driving me nuts(er). It doesn't do it all the time either.It has only 65,000 miles on it and never towed. I know I am due for a total tranny flush since it never had one. Could this be the whole problem? Iv been reading other stories that sound close to mine but they never mentioned about the noise when pulling out. Could it be the rear end? I am totally lost on this one.Other then that problem it runs great. Shifts nice.
Ford F-150 (2009-2014) :: 2009 - 4th Gear Intermittent Slip At 88K Miles
Started a while back and comes and goes. Only commonality I have found is the truck needs to be warmed up for it to happen and usually after a few hours of driving. The downshift from 5th or 6th into fourth, at times, produces anywhere from a light to violent clunk, feels like a typical tranny slip. It will do it while in cruise and it will do it if I don't have the cruise on. Can't figure out if it is going to be a tune issue or hardware.
It does it only downshifting into 4th from 5th or 6th, no other downshifting is a problem and usually the 6th to 4th produces the worst results. At highway speeds that is usually a shift from around 2Krpm to just over 3K rpm (6th to 4th) if it is from 5th it is about 2500 to 3K. Start from a stop and go WOT and there are no issues.
Having it in Tow/Haul or not makes no difference as far as I can tell. IT can do it on one hill and the next time be just fine or do it 2-3 hills in a row. After this last trip it will do it at 9K feet or at 60 feet elevation, didn't make a difference there either.
Another issue that may be hurting the computer is the truck originally came with the 235 tires, it now has 285's and the rear is only 3.31. I plan on going with 265's and maybe still a gear change to 3.73's in the future. I usually only notice this on long trips, first was a 1500mile hauling an ATV, second was last week during a 2500 mile empty. Although I have had it do it a few times locally. I figure those bigger tires can't be good especially with that high of a rear for the management system.
IS F (2008-2014) :: Burning Smell When Accelerate
I get this burning smell when i accelerate all the way and it does not smell like gas, I don't know what it is. When I drive normally it's fine. When I stop flooring it, it stops to smell burnt. There's no engine light or anything either. I went to the dealer and asked around some mechanics and they can't find anything wrong.Its a 2008 with 133k miles and i just got it.

My drivers side seat is loose as in it rocks back and forward when I accelerate or brake. I have checked all 4 bolts they are all tight. I can't explain what i see (perhaps I can take a picture or video) but something under the seat looks irregular as in it's moving and shouldn't be. I have ECP but Lexus wants to charge $140 just to look and see if it's covered under warranty.

View 2 RepliesLexus GX 2004-09 :: 2007 GX470 - Noise Like A Slight Belt Slip When Engine Downshift To Accelerate
Few weeks ago I bought my first Lexus, an '07 GX 470. It has roughly 75,000 miles on it, 2 previous owners before me. Anyway, I hear a noise sometimes which either sounds like a slight belt slip or fuel being pumped into the injectors when I give it a good amount of gas and the engine downshifts to accelerate. I had the dealer replace the drive belt(serpentine belt) because of 2 reasons, it needed to be replaced and I thought that could be the problem(I did not have to pay for it since I have had some problems with the Lexus dealership I bought it from, they did it as a "goodwill" gesture, that's a story for another thread) and inspect the tensioner and pulleys, they said the pulleys and tensioner were in good working order.
I drove the GX home tonight after said replacement, and I still noticed the same noise. The best I can describe it is like I said above, a slight belt slipping noise or it could also be described I guess as fuel being injected under acceleration as soon as the trans downshifts to accelerate. I am just curious if this is normal for this engine or do I have a possible problem? It's covered under the Lexus used car warranty for another 5 months so if there is something wrong, obviously I would like it fixed under warranty if something is wrong. One thing I should probably mention is, the noise is semi quiet and I guess the average person might not even notice it.

I sometimes pulloff after a minute then Im off, but slowly until the engine temp gets to the middle. I won't go caveman on it until the oil temp is almost in the middle too (never quite gets to the middle for the engine oil temp)
Is this logic right? Lexus guy told me it'll warm up as you go. If it was like zero degrees out then yes Id let it idle for 10-15 minutes.

View 9 RepliesFord Super Duty (1999-2016) :: 2011 F250 - When Start To Accelerate In First Gear Truck Goes To Idle For About 2 - 3 Seconds
I have a 2011 F250 with the 6.2 gas engine. I have been having a problem that the dealership says there is nothing they can do and have never heard about.
After the truck sits all night I get in and drive it for 10-15 min. It gets warm and I get out turning it off. When I come back about 15-45 min later I start it up and go to leave. As I pull out and start to accelerate in first gear the truck goes to an idle for about 2-3 seconds. I push the gas pedal and get no response. After a couple of seconds it picks up wherever you have the gas pedal. If you have the pedal to the floor it jumps you forward. This is not putting on any lights and the computer is not throwing any codes. According to the dealership the computer is telling them there is nothing wrong.
This has happened 12 times in the past 6 months. It has happened since I bought the truck. I have just started documenting it as of 6 months ago. It is not something I can make it do on command. After it happens once it doesn't seem to do it again for a week or two. I have 31000 miles on the truck. The dealership has had it for 4 days now and can't seem to get it to happen for them.
IS F (2008-2014) :: Clunky Shifting From 1st To 2nd Gear
Ok, so in M mode shifts can be a little rough from 2nd to 3rd unless I give it enough gas. It's no big deal and my car has always been like that (owned it since 9/2013). But as of yesterday, shifts have completely changed from 1st to 2nd. It is clunky, extremely quick and lurches forward every time in M mode. It has NEVER done this before and it kinda sucks.
I've read all of the threads regarding tranny fluid, belt squeak, etc. and haven't specifically found anything like this. I haven't done anything to the car except the ELF recall and an oil change about a month ago.
IS F (2008-2014) :: CEL And VSC Light Both Lit And 1st Gear Is Locked Out
Starting here to ask first but I currently have the CEL and VSC light both lit and 1st gear is locked out. What is causing this without having the codes read yet? Is it common to get both of these lights simultaneously? Having 1st gear locked out seems very concerning from a mechanical aspect to me, should I have it parked till I get it serviced?
