The lexus sc430 is nice but when I floor it , there is a 2-3 second delay until she kicks down and really takes off. Someone said there is actually an adjustment on the transmission to eliminate this delay. Never heard of such a thing.
View 3 RepliesI have a 02, sc430. Modded with blitz supercharged and straight exhaust all the way..( accept the 2 catalytic converter before the o2 sensor.) But I have slight delay or lag during the first gear. From (rpm) 1k to 4k its delay or lag.(not revving smooth). But when its reach 4k and above, the power just kicks in suddenly.
View 6 RepliesSituation: In automatic, coming off say a highway in the 30 to 50 km's (20 mph) range and then trying to accelerate quickly but there is a 1-2 second pause/delay/lag before it kicks in and launches.
It is not 100% consistent but it happens often enough to bother me.
Experience with this issue? What is the cause and is there a fix?
I have recently purchased a 2007 Lexus and just starting having a problem when trying to accelerate when I first start to car and try to move forward.
Basically I put the car in drive accelerate, the RPM is high but the car moves at a snails pace of at all.
I own a fully loaded 2014 Lexus IS350F and noticed the Enform/Radio/Nav has about a 2 minute delay of booting up when the car is first started. I literally can't change the audio source, make a call, etc for nearly 2 minutes. I never experienced this on any other car. My 2007 Acura TLS was instantaneous. What's the deal with Lexus?
Also I noticed the Nav system does voice commands over the radio rather than muting the music. Any way to change that? Some odd choices Lexus made here and I hope I can tweak.
The headlight stays on for about a minute after the car shuts down. What is this term called? I want to set the timer of this delay shorter. Right now it feels like a minute to turn off the head and tail lights.
View 3 Replies2006 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.

View 6 Repliesi have noticed ever since i got my 15 rx that on hot days when i get in, and start it up. there is a pretty long delay before the a/c starts blowing? kinda stinks when its hot out and the inside of the car is even hotter? all i know for sure is my 01, and 05`s used to come on almost instantly, so just curious if this is just the way its supposed to be on the 15.
View 8 RepliesI 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 need to replace the ECM in an 02 SC430 my question is.......?
If i get my hands on a used one will I still have to Reflash the ECM or will the car start run and drive plug and play?
New owner of a 2007 and 1st post. My antenna goes all the way up and then one of the sections retreats.
View 8 RepliesJust bought my sc and the top won't go down,when I press the button nothing happens no blinking lights or noise.if I open the windows and press the close button the Windows go up,but when I press the down button nothing happens.
I have the trunk cover close and I checked all the fuses in the trunk but they all seem fine nothing blown that I can see.i disconnected the battery overnight and still nothing. I also checked in the glove box and the button is pushed in like it is suppose to be.
Is it possible to turn off antenna when CD is on?
View 7 RepliesA few months my AC starting blowing hot air. When I was at the dealer, they claimed the compressor was bad and wanted over a 1000 to replace. I looked online when I was there and said the new denso compressor was about 300 online. They wanted double. I just left and didn't worry about it since it was about winter then. Now I need to get it fixed.
A guy noticed the other day when I cut the AC button on, the clutch engaged and cut back off. He didn't have time to fully check it that day and wants me to bring back if I can another day.
I did some searching on this board, but haven't seen compressor issues with the SC430. I have a 94 ES300 and a 2004 RX330 and neither have had compressor issues. So I am shocked at this anyway.
I bought a relay, but that did not work. I just read on the LS forum that a lot of people have had problems with the AC pressure switch.
I understand that switch could prevent the compressor from coming on when the switch goes bad. Do we have that switch on the 06 SC430? If so, where is it? I can't find a part number listed in All data. I would love to check it before spending a ton of money on compressor replacement.
By the way, I have plenty of refrigerant. They checked that at the dealer and added some then. And I did AC diagnostics and show no codes.
I thought my top used to go down in drive when I was at 0mph, but recently it only goes down when the car is in park. Maybe my memory is just bad but does everyone's sc430 top go down in park only ? Or can you also drop the top when you are in drive at 0mph? Maybe it never could drop the top in drive at 0mph and my mind is playing tricks on me!

View 7 RepliesThe top of my 2004 SC430 got stuck halfway open and I put it up manually. Now it does not work at all. The dealer told me it would cost $8,000 to fix! I love this car. How I can get the top fixed without going bankrupt?
View 3 RepliesI thought I'd post an update about my front end shakes that I've been working on eliminating since I bought my SC. They used to occur anywhere between 55-70 mph. The remaining shake occurs around 65-70 mph. I should mention that when I added H&R 25mm wheel spacers in the back and 20mm spacers in the front. I had the shakes both before and after adding the spacers though. The following list is what I've done over the past couple of years to try to eliminate my shakes:
1) New tires - Bridgestone Potenza's, nice tires, better ride.
2) Replacement, chrome, OEM wheels. Look nice.
3) Road force balancing.
4) Steering rack was replaced with a rebuilt unit because the old one was leaking. Came with inner tie rods and I put on new outer tie rods at the same time. No change in shaking.
5) Daizen polyurethane lower control arm #2 bushings.
6) Daizen upper control arm and lower control arm bushings.
7) Daizen steering rack polyurethane bushings. Still not perfect, but this made a huge difference.
I did the steering rack bushings today. I've really, really developed a dislike for Lexus steering bushings!
Some background: I had issues with my '01 LS430 steering bushings @ 85K miles. My only choice was to replace them with OEM. I should have replaced them at 50K. They were really, really awful. The interesting thing, though, is that they physically looked pretty good. The result is amazing; nice and tight.
The bushing design of the SC is essentially the same as the LS. But luckily we have more choices with our steering rack bushings than the LS crowd. I began to hang around the GS guys because their front end is quite similar. The '98-'05 GS430 uses the same steering rack and bushings as our SC. Sewell sells both OEM and an aftermarket polyurethane solution for around $30 complete.
At this point my SC tracks very, very well. The polyurethane suspension bushings probably add a bit of harshness to my ride but I don't find it objectionable and it's a reasonable tradeoff for the added precision in the front end. I don't believe that the polyurethane steering rack bushings have any tradeoffs at all. The remaining shake that I'm experiencing is pretty darn subtle but I'm not done. I'm going to rotate the tires tomorrow and see if anything changes. I'm also looking at toe in. My front tire wear tells me that I don't have enough. I've been running factory settings but I'm going to experiment with a bit more toe due to the additional road forces created by the wheel spacers. I don't give up easily!
I insert the key, turn it all the way to ignition, car starts, dash is lit up, everything seems to be working. Once I let the key snap back from IGN to anything else, the engine continues to run, but the car acts as if it is off (dash completely dead, wont come out of park).
If I remote start the vehicle using my luxlink (which I've had zero problems with since it's install about 4 years ago), car starts fine, dash lights up, everything is in working order. However, I have to put the key in to unlock the steering wheel, and once I depress the brake, again, car acts as though it's off (no dash/radio/nav, anything electrical, won't come out of park), but the engine continues to run.
My dash lights are very dim during daylight and marginally bright at night. This is for a 2002 Lexus SC430.
