Lexus RX 2004-09 :: 2008 RX350 - Excessive Slipping Or Delay In Response In Transmission
Sep 15, 2007
I have a 2008 RX350 AWD with only 500 miles on it so far and I am starting to get concerned about what seems to be excessive slipping or a delay in response in the trans. Under normal forward driving the trans seems to shift very smooth. The problem occurs under situations where I am coming to a near stop, basically coasting, and then have to accelerate again to continue forward. This could be in a slow moving traffic type situation or when maneuvering through a parking lot. When I try to execute a small increase in speed the engine revs but the trans doesn't respond.
It's as though it's in neutral and unable to decide which gear it should be in. After a 2 to as long as a 5 second delay it finally engages and moves forward. The condition is even worse if I am heading into a slight incline. Once it is engaged everything is fine and the subsequent shifts are very smooth. When starting from a complete stop it works perfectly. I've never had a transmission slip this much in any vehicle. There was one situation where I was almost broadsided because the RX delayed in moving forward.
I realize this is a subjective call but I am trying to determine what level of slipping in the trans is considered normal under the conditions I've described. I have searched and read past threads about issues with the earlier model years but I thought they were resolved by now. I haven't taken the RX in for service yet but I fear I will get the standard - everything is working as designed - answer from my dealership.

I have a 2008 Accent (base model for the most part, no C/C), and my transmission seems to be slipping a bit. The symptoms are: slow acceleration, a delay in gear shifting, and after the 30MPH mark, it takes forever to get up to anything near 60. I just wanted to know if it's a simple solution such as topping off the transmission fluid, or if it's a bigger issue.

Experienced excessive road noise with RX350? I have a 2014 with Dunlop tires, and on certain types of asphalt roads the road noise is incredibly high --- on other types it is unnoticeable. I'm thinking it might be the tires, but I'm not certain.

2006 GX470, ~65k mi. When shifting from P to R, P to D, or R to D, the transmission often (but not always) seems to have to think about it a while. When it shifts fine it takes about 1sec for the transmission to change gears. When it's being cranky it takes ~4secs. There are no other symptoms.

My 2007 RX350 has 14500 mlles. After almost coming to a stop (5mph) and at times that I need to accelerate quickly while traveling at approx 30mph the transmission wants to hunt for the proper gear. ILO downshifting to the next lowest gear it does nothing but hunts for a second (seems like a minute with traffic approaching) then grabs a gear. Engine RPM revs naturally but too high. Dealer states this is normal for the hunting action. The vehicle is perfect other than this one small problem.

I have a 98 GS4 and a 04 RX330 and one major issue I have with the RX, is the poor downshift response when slowing down, to say 5-10 mph and give it gas, the transmission takes FOREVER to realize I want first gear. If I am giving it 50% throttle at 5-10 mph after slowing and needing to get a move on, the throttle seems like it is there, but the transmission takes an eternity to realize "oh, you want first? hang on while I think about it", then it grabs first and LURCHES forward, giving everyone a very uncomfortable jerk.
My GS however, when down to those speeds is always spot on the right gear. Yeah, I know its comparing a GS to a RX, but wouldn't you think that Lexus would figure that one out?
Is the 04 worse than 05 or 06? Can I use an 05 or 06 trans controller and get some improved transmission response?
You can tell by the lurch, the throttle is responding to the driver's throttle pedal input, but the transmission isn't figuring it out till way too late. I don't get the lurch like at slower speeds and higher throttle input, but it sure makes for a poorly driving car.
I see the same problem when taking slower corners, get it down to 10-20 mph for a corner and the transmission won't downshift till AFTER the apex of the corner, despite what throttle pedal is pressed.

Transmission won't go into drive until I give it gas and then hard shift between 1&2 then a little slipping when I get on it in higher speeds , fluid and filter brand new, threw a speed sensor so code I replaced with new but no change, don't know what to do and can't find out why speed sensor code went off changed but didn't fix? Can't drive truck!!!

I have a 2004 4x4 with 305K on it. Never changed the transmission fluid and I think its slipping a bit.
Beentold that I should not change the fluid because the new fluid would somehow damage something and to just not worry about it.
So OK to change the fluid or not?

I purchased this truck about 2 years ago, with about 70k miles. Previous owner had transmission work done, but I'm not sure if it was a rebuild, new, or refurbished. About 8 months ago I experienced hesitation, and frequent stalling when coming to a stop. Pulled the engine codes, and they said it was throttle body related. I thoroughly cleaned the throttle body assembly inside, with the battery disconnected, went through the idle re-learn process, and it drove fine for a few days. Took it into the shop, and they did a tune up and replaced several plugs and coils. Since then, it's run great.
A couple of weeks ago, a whining/buzzing noise was coming from the engine compartment, getting much louder as RPMs increased. Got the oil changed a week ago (it was overdue), and the tech at the quick lube shop said the noise was from the drive pulley(s), and that they should be replaced.
Today, I was waiting for the parking lot at work to open, sitting in park. I quickly switched to Drive, and the trans didn't seem to engage (Auto Trans). The engine revved, I let off the gas, and it then engaged and I scooted into a parking spot. After work, on the way home, there were similar issues at the beginning of the drive, mainly when slowing down/stopping/down-shifting. Most of the drive was on hwy, and I managed to get by okay going around 60 mph, with some spikes in RPM's occasionally when I would accelerate (no Tach, so I'm going by sound). Half way home on the high way, the O/D Off light starting quickly blinking, and the odometer screen read "TRANS FAULT". I managed to make it off of the highway, and stopped at the first red light, where the engine stalled. Turned it back on, put it in gear, and it drove fine for about 5-10 minutes on back roads, with no lights/notices. The last 2 miles home I experienced a lot of slipping, and high revs. When I backed into my parking spot, there was noticeable leaking... Trans fluid was leaking fairly quickly. I hadn't noticed any trans fluid leaking before today... I went out to run the engine and take a short trip to warm up the fluid to get a reading, but it wouldn't engage in Forward or Reverse at all. Pulled the dipstick out, while "cold", and there was nothing... I'm assuming that it's drained drastically, and is extremely low or gone.

I can't get an accurate reading on my dipstick of my '08 RX 350. I just tried after it sat all night and the oil is over the full marks. I just had the oil changed at Lexus and they used my 6 quarts of Mobil 1 and I told them not top it off to 6.5 quarts because I wanted to.
The tech said he did not add more than what I gave him. I just called Lexus and they said, yes it is difficult to get an accurate reading for some reason. He said check when the oil is warm and has sat for 5 minutes. Any others have trouble reading the oil dipstick accurately?

Have a 2008 RX350. It is our first Lexus product. The dashboard has begun to crack. Now has 4 cracks of various sizes. Contacted Lexus they said too bad. This should not happen to a Luxury vehicle. Sure makes the interior look like crap.

Was wondering, there is a crack in their shifter bezel?

How to disable the seat belt alarm on a 2008 Lexus RX 350? I tried the "reset odometer" method and that doesn't work. I also took the car to a Toyota dealer and a former Lexus technician could not disable it via computer. This alarm is annoying!

Bought our first Lexus, 2008 Rx350 in March of 2012. Was fed up with our 2010 Ford Escape. Bought the Lexus because of their quality reputation. Shortly after purchase cracks began to appear in the dash. Now have 5 cracks and chunks are beginning to fall off. Contacted Lexus. Even though they know that they have a problem with the dashes they will do nothing.

I just purchased my first Lexus (very exciting!) But one puzzling issue I've noticed and not sure what the problem is, if it's me or my vehicle. The back cargo cover wont' stay closed. It keeps popping out/up and opening. Quite annoying already and I only had it a few days. Subsequently, it's not hiding a thing in the back.

"VSC OFF" light came on the other day. I took my RX350 to the dealer. The dealer said Heater Element sensor is bad. They didnot have this part in stock. I googled this part. Nothing comes up under that search. I took it to Autozone and the code came up as Mass Air flow sensor. Are both of these same thing?

I just got my TMPS light on this morning, check pressure all 4 tires are good, 35 PSI each, did not check spare tire, does spare tire had TMPS sensor? what do you think? is one of my sensor is bad?

2008 RX350 with 52k mile .... It's getting cold even in Atlanta. So I thought the warning light was perfectly normal..
Checked the tire pressure and was around 31psi, so pumped to 35 ish after running 10 min or so thinking it should be good enough. After driving back home, the lights are still on.
I double checked tire pressures and they are between 35 and 35.5 psi still. So I reset the warning light, and it the light won't go away. I think the owner's manual said, if it blinks for one min and stays on, then there's a problem in the sensor.
When I start, it blinks once, then stays on.
If I reset it, it blinks three times and stays on.
What I should do next? I did replace tires about a year ago at the local tire shop, but I don't think it was their fault, as I think the warning light worked fine last winter.

I have a 2008 RX 350 and I am experiencing issues with turning the key ignition and having the steering wheel locked. It gets locked and after several attempts at jimmying the key it eventually starts. My concern is that if I keep this practice up I will damage my key. I have addressed this issue to the dealership and I was naive and trusted them with fixing the problem with my last maintenance visit. Thinking the the problem was solved I started to experience the same problem again. I was first told that it is possible the my key chains are too heavy which could of caused the problem but I lightened the load and still have this problem. I've read about this problem with other people but there doesn't seem to be a solution.
One thing I have noticed is that I tend to experience this problem during the cold weather. During warmer weathers I don't have issues with the key ignition being locked but now that it's cold I am having the problem again (not sure if this has to do with anything). Do I need to change a part out to fix this? I've also read that there can be dirt in the ignition which needs to be cleaned out. Will this work and if so how do I do clean it?

I've had my 2008 RX350 for 2.5 yrs now and just love it! However, over the last 8 months or so, I've been having a strange annoying problem. And a few times, the car has left me stranded. What happens is I turn the key and my first indicator is that the steering wheel doesn't adjust and I know the car is not going to start. However, the radio may work, dash lights work, steering wheel is not locked. It seems entirely dead as if the battery is dead. The car may start 15 min later or may take 3 hours then decide to start.
A strange thing is, is the windows don't work following these episodes which normally signify a battery failure, however the battery is not very old, otherwise performs perfectly and the dealership tested it and say it's good. Because this is so intermittent, they couldn't re-enact the problem so I'm stuck with being stranded again....usually 6 weeks later. The dealership has no answers. I was lucky last night because the car started after 15 min. 6 weeks ago, I was stranded 50 miles away from home where I had to leave the car overnight after trying for 3 hours to get is started.
The next morning, it promptly started. I am at a total loss and it makes me nervous to drive. My husband who works for a chevy dealer and knowledgeable with cars is stumped. He asks the question, could there be a computer malfunction after so many starts which would answer the 6 wk consistency for which this happens? Should we just replace the battery even though we have no reason to suspect?
