Lexus RX 2010-15 :: Check AWD System Message / Hard Jerky Downshifting
Sep 9, 2014
So I just purchased my new-to-me, CPO 2010 RX 350 two weeks ago. It had 81,750 miles when I purchased it, and it now has about 83,000 miles. I just came back from a weekend vacation, having driving about 500 miles total. This morning when I turned on the car, I noticed a message saying "Check AWD System," the check engine light was on, the general warning light was on, and the traction control light was on. As I was driving, I realized that the car wasn't downshifting properly. I didn't drive faster than 40 mph on my morning commute. When the car did downshift, it was a hard, jerky shift.
I did some reading on the forum, and many people suggested all the warning lights could be fixed by taking off and retightening the gas cap (due to the vehicle not reading the emissions properly or something?). I also read that topping off and overfilling the gas tank can be cause for the warning lights to go on. I did fill up once on my way home from my vacation, and haven't filled up since.
Anyways, I just now tried to adjust the gas cap and then restart the car, but the warning lights are still on. What I should do or if I should drive it a bit to let the emissions build up again? My problem is is that I live about 6 hours from a Lexus dealership, so I'm trying to figure out if I can resolve this on my own or what I should tell a mechanic specifically if I need to take it in.

I have Lexus 460 LS L 2007. Few months back changed the battery and every thing was ok. 2 months after I had problem in the sound system ( radio and dvd ) which was on and off. One month back suddenly I had all the warning lights in the dashboard on with massage saying that that the brake system is malfunctioning and check the ABS system.
I took the car to LEXUS dealer and they reprogrammed the computer abd then every thing went back to normal and the problem fixed. Two days after I had these warning lights again with the same massege. I do not know what to do ??

Searched for threads about this error message, didn't find much substantive except 'check your gas cap'.

I cleaned out hybrid battery cooling fan today, not too bad after 160K . However, as I test drove prius the Triangle of death and "Check Hybrid System" message pops up.
Drove 13 miles back home, battery charged good. No power consumption data given on hud. Rechecked fan connection and looked over area. All looked good. I dont think ICE was running during drive home. Tested 12 volt=good. Disconnected 12 volt and orange plug. Reconnected. System reboots and seems Ice goes through warm up. Even put in power mode and it roars. Scratching head on this. Coincedence or maybe I should have disconnected 12volt before disconnecting cooling fan?

I have a 2003 GX with DVD & NAV. The DVD gives me a message on the rear screen that says "Disk Check" and then never plays the disk. I tried multiple disks and am pretty sure the DVD unit is toast. Looking forward to replace the DVD unit in the center console?

I Opened my 2011 Prius trunk to get the tire wrench to take my snow tires off, and install my main tires and rims. When I went to start up the car after it was done, I have a "Check Hybrid System" Message on the MFD. I wondered if I'd hit one of the 2 orange items on the Electric drive battery, that was exposed in the trunk, and I can't get rid of the message. The car is not drivable, the system doesn't read "READY" and the engine doesn't start.

I was driving down the road and suddenly the car stopped. The check hybrid system light came on, and it wouldn't go forward or backward. I had to have it towed. What has happened? Is it included in extended warranty?

1. I think my battery is getting weak.... when i cranked it, it didnt sound strong and the original battery eye says to add distilled water. I am thinking about getting a replacement battery at Costco.
2. so right after it started, the message of "Check Brake System" shows up. Tried to restart but no go. Drove about 15 miles and all seems fine but message is still there.
* is it OK to replace with a Costco brand battery (they have a great returns policy) and is there anything i need to do before or after replacement?
* could the Check Brake System be due to the weak battery? How can I reset it?
* Anything else that can cause this error message?

My new-to-me (bought in May this year) 2010 Prius last night suffered. Nearing home on my usual 21-mi commute from work and on a secondary road, I was stopped at a red light. As I normally do when at a red light when a rather spirited start isn't needed (no or few cars behind me, not uphill, etc) I pushed the "EV" button to take advantage of electric acceleration up to 25 mph. All seemed normal as the light turned green and I started off. I don't know if I reached 25 or not - must've been close - when all of a sudden the acceleration stopped as if I'd taken my foot off the pedal when indeed I'd not. Simultaneously, a circus of lights lit up on the dash along with the fairly ominous message of "Check Hybrid System."
As with all things electronic these days, I figured a good ol' fashioned reboot was in order. Turned it off and back on and...same thing of course. Being near an intersection and a very bad place to be stopped - and not knowing if the car would actually move - I pressed the accelerator anyway, despite the warning lights, and indeed the car started to move. It seemed to cap the speed at 12-13 mph, which immediately seemed like some kind of self-protective safe mode. Luckily, I was within spitting distance from home, so I limped the last 1/4 mile in this state - and at 12 mph.
There are probably 5-6 warning lights on in addition to the big "Check Hybrid System" message. Let's see, first and foremost, the yellow triangle of death, followed by what I think is the Slip indicator (car icon with wavy lines), the CEL, the encircled exclamation point which I think is the braking system, and I forget, a couple of more. I should've snapped a pic but I was in a hurry to troubleshoot.
So I used my Actron scanner to pull the P0A94 code. I didn't see that it's able to read the sub codes, or maybe that's a capability that only the expensive dealer scanners have. Anyway, I can't conclude what it is other than the generic "DC-DC Converter Performance". I know that here and elsewhere there's a list of all DTC codes, and I saw that this code has 17 sub-codes, many of which are related somehow to the inverter, which seems to have been the subject of a recall in Gen II models (acutally the inverter cooling pump IIRC) but not on Gen III.

I have a 2010 Prius, currently at around 69,000 miles. Back in Feb 2015 (when it was just under 60,000) I was driving on a city street and hit the accelerator once a stoplight turned green - immediately as I took off (at a normal rate of acceleration) my 2010 Prius made a loud noise and I got the red triangle of death, with a "Check Hybrid System" message. The car quickly shifted into "limp home" mode and I was able to make it back home as I was only about a mile away.
Got towed to the nearest dealer the next morning and after tons of testing and going back and forth, they replaced the transmission and inverter (was able to get it covered under powertrain warranty), and I was on my merry way. No issues until last night.
Yesterday evening, I am on a city street and get a warning beep. I look at my dashboard and this time I have a yellow exclamation mark with the "Check Hybrid System" message yet AGAIN. Towed the car to the nearest dealer and am now waiting on next steps. Only update I've gotten so far is that they are still trying to diagnose the issue, and are getting 4 error codes in this process, 2 of which are new. I am waiting on the technician to tell me what the actual codes are - hopefully should get them tomorrow.
I would hope if it's another issue with transmission or inverter, it's covered under warranty given I replaced both less than a year ago. However I'm not sure and am worried that it's going to be $$$ in case it's something else that failed. Plus I'm getting serious doubts as to the safety of my car - what if I had been moving at a high speed on the highway during either of these situations?

Went to start the car up this morning - foot on brake and pressed the Power button. The car went through its checks but when it finished the 'Welcome to Prius' graphic it did a continuous beeep and displayed 'Check Hybrid System' and didn't start.
I turned it off and tried again and on the third or fourth attempt the car eventually fired up, the error message was gone and there were no warning lights on the dash. The car did smell like it was running rich though.
I turned it off and called the dealers. They said if no warning lights are now on it should be ok to drive the 6 miles to see them and they'll check it on their computer. As I drove to see them the car was running OK but the fuel economy was shocking. I was getting about 40 mpg UK (30 US mpg) as a trip average.

My Prius yesterday while driving slowly (under 10 mph) all the dash warning lights came on(triangle, cel, trac control, brake). the gas engine started and the message came on that says: "check hybrid system". Today when I went out to check there only two warning lights on (triangle and cel) with the same message displayed. My question is can the vehicle operate without damaging anything if I drive it as is? I have read on several threads that the engine will not start if the hybrid motor(s) are not working. Since my engine starts and runs I have to believe the motor(s) are working.

So with all of the snow we've been having in the north east this is usually an error message I get almost every week. Normally this is due to the front sonar sensors being covered in ice or snow and will go away once it melts when I'm parked in the garage or is washed off.
However the past few days, I've had the car washed a few times to make sure the salt is off of the sonar on the front bumper but I'm still getting the error message stating to check the front sonar. If I leave the park assist on it works for the sides but not the front and the error message still stays on the screen. I've hand-washed the sonar sensors several times and 'massaged' them in place to maybe break up some ice behind the bumper or get the sensor to work but I've gotten nothing. Upon further inspection, one of the sensors has a deep scratch in it to where you can see past the paint of the car slightly.
I'm really not looking forward to taking the car to the dealer to have them look at the sensor because they will most likely charge me a ton. I saw a few other posts on the forums about the LS400 from '99-'00 having a similar issue and it cost them $550 to get it fixed. Obviously it's not the same car but I'm expecting a similar quote. I'm assuming the paint scratch is what is causing the issue as another post for the LS mentioned the same thing and said they had to scratch all the paint off of the sensor to make it work again.

I have a 2006 RX400h. On 3 occasions I've been stranded. The car won't start and I get an error/message Shift to P when Starting. However I am in Park. It's coupled with a Check VSC System warning. Service department says I have just drained the accessory battery, however nothing is being used other than standard equip such as lights, dash etc. I've had all batteries changed in the car over the 4 years I've owned it. Is this usual?

The "Check Hybrid System" message came up on my dashboard. I took it to the dealer, and they said the temperature sensor on the transaxle was giving erratic readings. Unfortunately, they said that the only way to fix it is to replace the entire transaxle. They said I could keep driving it and that it would probably go into disabled mode before it caused any more damage. What I should do? It's a rebuilt 2012 Prius with 25k miles.

Is it common to have significantly harder downshifts in S-mode versus regular D? In D-mode the car very much feels like an "auto" through and through. However, when I am in Sport the downshifts are much, much rougher...very "jerky". I'm assuming this has something to do with rev-matching but...even when I'm just crusing in S-mode and coming to a slow stop it jerks between the gears.

I have a 2010 rx 350 and my wife was in a little bump with the garage. There is a small crack in the right headlight and I sealed it but some dirt has now entered and now the light comes on to "Check AFS System" It is costly at the dealer so I am looking for replacement light. In the meantime, is there a way to shut that off the main cluster as it's terribly annoying...
