Lexus GX 2004-09 :: 2003 GX470 Normal Drive At 2Krpm But Slow To Pick Up Speed
Apr 25, 2014
I would like to post this performance issue on my 2003 GX470_79Kmiles which happened on the freeway yesterday. The sequence:
1) During start and at idle/stationary, the rpm shoot to 1100rpm and stayed there for a while, i would think that it was normal since the engine was still cold.
2) Drove to the freeway, I noticed that speed is very slow to pick up. My normal driving experience was that at close/equal to 2000rpm, the speed usually at around 70-75mph. But there was a considerable reduction of speed at around 60mph at almost more than 2000rpm, plus a buzzing engine noise. I tried to really rev-up the engine but very sluggish to pick up the speed not even close to 70mph.
3) Drove the car to lexus shop this morning, top speed of 60 to 65mph and tried to rev it up to plus 2000rpm to pick up speed, but the engine noise is very abnormal.

I have had an issue with my GX470 almost since I bought it in 2008. It will sometimes not engage in drive after backing out of a parking space.
It usually happens when it is warm and the car has been driving for awhile then I park for lunch or an errand. I come back start up the car put it into reverse backout of the car space and nothing for a good 5-6 seconds. Seems a lot longer when cars are waiting to take your space and honking.
Anyway I have been reporting it to Lexus at every service and getting a no trouble found. Over time it is occurring more regularly and it even happened at the dealership but of course I was the only one in my car at the time.

New to my 2008 GX470. 100k miles. Love it so far. However I think I am hearing a intermittent rumbling as I drive down the road. It is like the rumble from a radio base sound. It could be normal road noise but I bet it is not.
I have replaced the left front axle (grease boot broken), replaced the rotors and pads, replaced all differential and transfer case fluids (not transmission yet) and inspected all the suspension parts.

I have a 2005 GX470 with 96,000 miles. Yesterday, while going on a 500 mile road trip the car stalled suddenly while traveling about 75mph on the interstate. It would start surging and then just stall completely. I pulled over.. Let the car sit for a minute and then it started right back up with no trouble. It did this to me 4 times on the trip about 80-100 miles between issues. The last time it was while accelerating hard up hill. All other electrical functions.. Radio, lights, etc... continued to work fine. I don't recall the cel ever coming on and even if it did it wasn't on when it restarts. It was 100 degrees out.
I'm on vacation so wanted to get it checked put before we head home but curious on thoughts of what it might be? I was thinking clogged fuel filter or MAS but the fact that it restarts right up after stalling makes me ink it might be more of an electrical issue.

Alright so pretty much every night my alarm on my 2003 lexus gx470 keeps going off i just want to unhook. Where I can unhook the alarm at so it stops going off is it under the dash or where?

Problem is noise that you can describe as clunk, not any harsh or sharp sound. It appears on road bumps or unevenness during slow speed up to about 40kph/25mph. The noise has not been heard over that speed even in bad bumpy roads.
List of thing I've done so far:
- Driven with empty rear compartments
- Driven with open rear door
- Checked the tightness of spare tyre
- Replaced rear stabilizer bar linkages
- Replaced rear stabilizer bar bushings
- Replaced rear axle carrier knuckle bushings
Could it be possible not coming from rear? Should I sit in the cargo space while somebody else driving, any success with this? What to do next?

When I started the vehicle this morning and shifted into reverse, nothing happened. I turned the car off and restarted it. It made a noise and I shifted back into park. The A/T P light came on.

My rear air suspension keeps dropping. Sometimes my suspension goes down all the way when parked, but not all the time. When I start the car it goes back up. It's a 2003 GX470.

Just purchased a 2003 GX470 with 160k and after the low brake fluid light came on I noticed the master cylinder had a leak. After removing the cover it appears the fluid has leaked for quite some time as the paint has started pealing from the frame. The brakes however appear to be working correctly. Upon purchase the front calipers were seized and I replaced both front calipers.
After having someone depress the brake pedal while I watched, the fluid leaks from the end of the master cylinder each time pedal is pressed in.
After doing some research it appears there is a rebuild kit for the master cylinder.

I bought a 2003 GX470 a couple of months ago and love it. It was a good upgrade from the 98 Land Cruiser I had a couple of years back and much better than my recent X5. Even though it runs great right now, I have one issue bugging me.
The Navigation unit hasn't ever really worked. Actually, it works, but since I bought it has used the secondary system which calculates location based off direction and speed which is only accurate if driving 50 yards or less - even after calibration
I found out how to get into the secret menu and looked through the settings. When I go to the screen which shows connected satellites, it says "Ensure nothing is blocking gps reception." I've tried a couple of resets, but nothing seems to work. I looked up where the antenna is to see if the connections is loose, but the only reference I found said it was on the rear glass. Unless integrated into something, I don't think it is, though.
The system still runs a factory 2003 disc for maps which is Gen 3. I tried a used 2007 map disc which upgraded the system, but didn't work. It gave disc errors so had to go back to the 2003 one. I haven't had a GPS signal since the day I bought it.

When I come to traffic and slow down, I have this jerky feeling when I'm coming to a stop. It's not from my brake or transition from gear changing. It's repetition of jerky feeling, not like one jerk from second to first gear.
For example, I'm in my first gear and stopped on the road. If I release the brake pedal and do NOT press gas, my car slowly moves forward with this jerky pulsation. It also makes noise (well.. I can hear it through my exhaust) while it moves. It feels like car is about to move, then stops, then moves, then stops.... I don't really get this when I apply gas.

My 03 GX470 has an issue where the windshield wipers will randomly stop working. It doesn't matter what setting they are on, auto, low, high, they work fine for a few minutes, then just stop mid stroke. They sometimes start back again on their own after a minute or so, but usually, I have to turn the switch to other settings a few times, to get it going again. Inevitably though, the wipers only work for a few minutes more, before stopping again. What could be causing this?

Changed the battery in my 2003 GX 470 today and all hell has broken loose. I have been able to reset my windows and moon roof but my Nav has a mind of its own.
MAP, DEST and MENU screens are all blank. However CLIMATE, AUDIO, DISPLAY works perfectly.

Like the subject says, I have been noticing over the last 2 months in my 03 GX470 that the interior lights and open door dash light come on when accelerating.
-The issue is exacerbated in cold weather. I have double checked all doors and rear hatch are closed.
-I have gone around and checked all door sensors are functioning, not sticky, etc.
-I climbed in the rear hatch and had my wife shut it. When I push on the plastic under the window, the lights come on. When I push on the glass itself (and push MUCH harder then on the plastic) the lights do not come on.
Clearly I have an issue in the rear hatch trim area.

I bought my first Lexus, great car. 2003 GX470 with 106k. I have had one problem with the fuse for the dome light. This issue has been on going since I bought the vehicle a couple months back and I can usually fix the problem by just replacing the fuse. Now when I try to replace the fuse, the fuse sparks and blows before I can even put it into the slot. Obviously there is something going on here that won't allow the fuse to be inserted before blowing. How to rectify this issue?

I recently bought a CPO 2007 GX 470 with 110k miles. At no charge dealer made repairs re the Bulletin about clunk in rear when I slowly drive over speed bumps. Had all front and rear shocks raced with OEM shocks, and four new Michellin MS2 tires installed. Rear end still feels like is is bottoming out sometimes during regular local and freeway driving when going over different times of road bumps.
My 'i89 a Dodge Ramdharger ( only car I ever bought brand new off the lot ) with 174k miles and old shocks and original springs drives better over bumps and speed bumps than the GX. One Lexus dealer said the reason is because the rear air bags ( that are not leaking )do not fill up fast enough when going move bumps and that can cause the bottoming out feeling. My mechanic is going to check it over again. What could be causing the bottoming out feeling?

2001 Santa Fe 2.7L 4wd ... In December I bought this vehicle it only has 95K on it. When I drove the car home I noticed it needed brakes so I put brand new pads and rotors on the whole way around. I changed the oil, air filter, wiper blades, and made sure all fluids were good. I had the front spring recall done and also put some new sway bar end links on the front. The car runs fine and I am rather impressed with it. It does have some rust but I'm not to worried about that. This isn't my everyday car just a winter/extra car. Recently I have been getting some clunking only when going from reverse to drive and going slow. You get a clunk..clunk pause clunk..clunk almost like you have a flat but once I get the car up to speed it is fine and you never hear it again until the car sits a day or so and then it will do it again. I don't know if I have a differential problem or a u joint or maybe something with the e brake or rear brakes? but it is -3 right now outside and I would rather know where to start so that when I can take a look at it I know some things to check or what it might be.

My daughter has a 2006 Jetta and has recently experienced issues with acceleration. Merging on expressways and all of a sudden she can't seem to pick up speed and has to get over in the right lane because she is going so slow.
Been to 2 different shops, A neighborhood shop couldn't find anything wrong and neither can the Volkswagen dealer. No Error codes on the computer accept Knock Sensor. She's afraid to drive the car!

I am in search of a SC430. I know that from 02-05 it has 5 speed trans. 06 and newer has 6 speed.
Is there a big different in the drive? I just want to justify the extra cost for the 06 and newer.

For the past month or so my 05 TDI Jetta has been having some acceleration issues. It starts good and when i start driving it goes ok (but not as good as it should) but when the car gets close to 3k rpm it doesn't pick up speed anymore. I recently had it taken into a shop where they fixed other issues but they didn't fix this one. also sometimes it will accelerate faster than it did before it had issues but then it just stops picking up seed. I have looked up this issue but haven't found a cause for it.

I own a 2002 Ford Explorer and I need diagnosing a problem. Whenever I start to pick up speed it starts to buckle and I always have the 4x4 on auto and it still buckles.
