Lexus RX 2004-09 :: RX400H Not Starting With All Lights Coming On
Feb 28, 2015
My 2008 RX400H will not start, with all lights coming on: VSC, Check Engine, Check Hybrid, etc. Computer notes all coils are faulting P0351 - P0356 - although this is not likely the case. Battery at 12V. Engine will chug to turn over, then fault codes appear and will cease to attempt to start, with check system appearing. Tried, jumping, changing out 3 of the 6 ignition coils. Any thoughts? Started battery charged and reading 12 volts .. but could this still be the issue?

One of the bulbs went out on our RX400H and I wanted to see if there is a way to access the fog light bulbs to change them without taking off the front bumper? Also, I heard that the fog lights are a H11 but other sources say its a 9006.

I have a 2006 RX400h with about 110k miles on it. Recently, I noticed a rattling noise coming from what sounds like underneath the car when I'm going up hill (at or around 15-25 mph).

I bought a RX400h 2008 (from my dad) last week. I checked the rear fog light today, it does not work. Have some questions:
1) How many rear fog lights on 400h, only on the left side or both left and right sides?
2) My dad had never turn on the rear fog light, still it does not work, bulb or fuse problem?
3) Is it common that the rear fog light does not work?
4) Where is the fuse for the rear fog light located on the 400h?

how the bottom of the radiator of a 2008 Rx400h is attached? I have the radiator all disassembled except for whatever is holding its bottom to the car. I have a detailed pdf of how to remove a 2006's radiator, but the method of mounting shown for that year doesn't match my 2008.

Between about 20-30mph, on light throttle the engine/transmission of my 2006 RX400h makes a low groaning sound, sending a vibration through to the cabin. The engine just seems to be very rough at this speeds, like the engine is labouring. After exactly 30mph, everything is very smooth. It is also very smooth when running in EV mode at any speed.
The harshness/vibration only comes on when accelerating, so have ruled out tyres etc. The mileage is 85,000, and it has had a recent major service at a Lexus dealer. I use premium fuel.
The Lexus dealer had a look at the car for 1 hour and inspected the exhaust, engine mountings etc. but could find no faults. I went on a test drive with the service technician and he did notice the vibration.

My wife said that her keys stopped locking/unlocking doors. I checked the keys and replaced the battery just to be sure. No change. Older keys also couldn't unlock/lock the car.
Both keys can start the car and has blinking red LED flushing when any buttons pushed. Is there a "Remote" button somewhere in a car to allow remote operation?

I just purchased the car a few weeks ago. Horn doesn't work till I press about a dozen times and "get lucky".. Once it hits once I can usually beep about 4 times before losing it. I checked the fuse, looks fine. Haven't found the relay yet.
I suspect it is something in the switching/contacts/ground in the steering column. What I may need to replace in steering column?

It all started after I refueled at Mobil after a rainstorm a month ago. Could be coincidence, but right after that the car started jerking wildly and making a howling wind noise from the front. Thought it was the transmission. Brought to Lexus dealership, they told me nothing was wrong as I had low mileage on the car. There are NO Check Engine lights on the dashboard. Car "quieted down" after that, but the noise remains EXCEPT at high speed when it's quiet.
In addition to that, the jerking / misfiring continues at stops, reversing, and slower speeds on occasion only.
I tried Techron FI cleaner, but it has not made a difference. Filled up several times since then.
What's wrong?

Recently when starting RX350 the check engine light and Check AWD lights went on. Driving the car for a short distance it idled very roughly and had no power (could not exceed 50mph). Drove home, shut car off, and restarted within 5 minutes. All lights went out, and car performed well. No problems since....what could have caused this problem?

What the warning lights mean (red triangle with exclamation mark inside, and yellow icon upper left of display, 2005 Gen II)? It comes on after starting the ICE, used to come on intermittently, now it's all the time... my hunch is the suspension because the ride has been getting worse, with unusually loud sound from the wheels over potholes!

I'm having an intermittent problem with my radio. I have an '05 GX with Nav and I have installed the VAIS tech SLS. Everything works fine with the radio, but sometimes when I start the car the radio is turned off, even though the radio was left on when the truck was turned off. This is an intermittent problem and is possibly related to the VAIS unit. Is this a sign of a larger future problem with the Nav unit?

2004 Lexus GX470, for the last month experienced intermittent starting problems. Turn the key, one slight click first try,nothing after. Disconnect battery cable and reconnect, starts every time.
Then while driving a week ago the vehicle died, all electrical seemed fine, more like fuel cutoff. Now every attempt to start is the same sequence of events, first try one click. Second car turns over and won't start or if it does runs rough for a few minutes and dies.
Third try, the starter won't disengage until key is turned to off position.
Possibly the ECM? Immobilizer? It's obviously not a starter problem as disconnecting the battery caused it to start and now when it does start it runs rough and then dies.

I smell gas in the garage when first starting the truck. It's 2007 with 88k miles. I didn't do any general maintenance as bought it from the dealer and it shows oil change and other checks in the Lexus driver website.

Just today this happened out of the blue. I parked the car, turned it off, came back to the car, started it with the key, and the engine was cranking and making the proper noise, but it wouldn't start. It just kept trying to start but wouldn't.
Eventually I had it towed, but it turns out after a while it did manage to start.I don't want this problem to arise in the future, but I don't know what it is. Maybe a spark plug?

From time to time, and always unpredictably, the transmission acts up. When starting from a stop the car will not accelerate normally, putting me in jeopardy. Also, shifting automatically is a problem.
I tried shifting through the gears and got mixed and unacceptable shifting. Depressing the accelerator only increases the RPM, the speed hardly at all.
Is this a problem in the transmission or in some electrical control of the transmission?

I've been hearing a loud screech on occasion when starting the engine. For a while, I was not able to isolate it and thought it may have been the HVAC fan bearing or something, because it sounded internal. It hasn't happened overtime, but often enough. The other day, the door was open when I hit the starter and it's loud as H3!!. It'd without a doubt external and seems to taper of rather quickly after the engine starts. At this time, I'm pretty sure it's the starter, but may be belt tensioner.

Last week Wed my vehicle was not starting. Some lights would start to come on and then die out. I read the forums here and replaced the traditional battery. Perfect, started right up and no issues. Today, went to bring the kids to school and it did not start up. No messages, a few lights like before and it went dark. Is this an engine issue. I have not tried to jump the new battery yet as it is pulled forward in my garage. (Today being Tuesday and not even a week into my new battery). I looked around, nothing was left on so what is happening. It has just short of 80,000 miles on it.
