Prius (2010-12) :: TPMS Warning When Headlights On
Oct 10, 2010
Okay, this is a weird situation that I can't figure out. I haven't gone to the dealer yet, but I will have to before I hit 30,000 miles. (I'm at about 22,000 now) I thought I would pose this to the forum, for the interest, if nothing else.
A couple months ago, I replaced every lightbulb in the car (except for low and high beams) with LEDs from superbrightleds.com. They have worked wonderfully. I didn't install the new flasher module, however, because it's too hard to get to and I have no problem with the lights blinking fast.

TPMS warning light is sometimes on, sometimes flashes, sometimes off. Only 2800 miles. Checked your pressures @ 38 psi. Have had no tire issues, nails. Etc. Took to dealer today. Service advisor said too much air in tires. Lowered to 35 psi. I have doubts about their"fix". Time will tell.

With the temps at a all time low in the U.S. this week, my TPMS warning light has come on in my 2012 RX350. It will stay very cold for most of the week, so is it ok to drive with my warning light on.
I don't want to check my psi in the tires with a tire gauge because I was told a valve stem can freeze open in extreme cold letting the tire to go completely flat.

After setting TPs to 41F/40R and resetting the TPMS via the under-dash button, and driving the v5 around, I still get the intermittent then constant TPMS warning indicator. It's not the TPs. Perhaps it's the TPMS sensors?

I don't see the tire icon warning at startup. I have a 2014 Prius C-3. Does this model have TPMS?

I have a bad sensor in a tire that just had a flat. I have ordered the sensor for the wheel and I am wondering after I install the sensor in the tire will the 'reader' pick it up and reset itself or do I need to go through the programming of the new sensor? At this time the TPMS warning light comes on and flashes for a minute or so before staying on constantly. This tells me it's trying to read the tire sensors but there is a fault, which is the tire sensor where I just had the flat. Costco tells me that sensor reads 78psi, which is incorrect. The fact that the reader is trying to read all the sensors and getting an error makes me think that it might reset itself when the new sensor transmitter is put in the tire? Any chance of this resetting itself or will I need to reprogram the receiver unit?

I recently had new tires installed on my 2008 Prius and after the tires were installed she drove better than ever and I drove about 150 miles across Florida with no issues what so ever. But when I went for a drive this evening, after about 30 minutes of driving my TPMS light blinked for about a minute then stayed solid for about 3 minutes but then went out. When I got out of the car all the tires looked okay, I didn't have a gauge on me and I will check the pressures tomorrow.

So naturally I thought a nail had punctured a tire leading to a slow leak. When I got home I found no nail and the tire pressure on all four tires even but down to about 36psi.
I refilled to my normal of 40/38 and reset the TPMS with the button below the steering wheel. The light stayed on for a minute or two of driving then turned off and stayed off for my commute to work.
What I think probably happened is that I reduced from 42/40 to 40/38 recently without a TPMS reset. Then this morning the temperature outside was 55F and about 65F in my garage. When I left the garage at 5:20AM the TPMS light was off. I drive about 2 mile to the gym each morning and park my C for about an hour. This morning, when I got back in the car the tires had cooled to 55F and I guess that was enough to reduce the pressure far enough to trip my warning light.

My 2010 Lexus RX350 doesn't perform the complementary dinging warning when the lights are left on. Every car I've ever had, and even the Lexus loaners I get, dinging if I leave the lights on. This car? No.
The dealer is saying this is "by design" because it has auto off lights. That doesn't make sense, since the loaners all ding when I leave the lights on (yes, I checked).
What do I tell them to turn on to make this work the way "all other" vehicles work? I found something called "Light Remind" in "C Best Settings"
Warning LIGHT REMIND ON/OFF of headlight reminder buzzer ON/OFF ... Is this applicable to the 3rd Gen 2010 Lexus RX350? Also, is there some way I can do it myself?
This is in reference to having a warning when lights are in the "On" position. In the "Auto" position, it would seem reasonable that there is no warning. But in the "On" position, it seems reasonable to have the alert.

I have the dreaded intermittent loss of headlights with no warning. My diagnosis has confirmed that I have failing HID lamps and that I am beyond coverage by Toyota or the dealer. I have bought replacement (Philips DR4) lamps and have tried to replace them.
The first time, I tried to replace the driver's side by removing the fuse panel cover and relays, but I could not get the round, rear cover off the headlight assembly.
The second time, I tried to un-attach the top of the bumper to remove the headlight assembly, but I was foiled because the two philips-head screws holding the rubber bumpers and the top of the airfoil to the radiator frame were frozen solid. I have tried to PB-Blast them, but no luck so far. I am considering cutting them off and drilling out the remaining screw body, but I am afraid I can't get replacements. Besides, I really don't don't want to make this a bigger job than it already is.

I purchased a set of Scion FRS wheels. I assume these have TPMS sensors installed. I found the reset button under the dash and followed the directions in the manual. The light still hasn't gone off.
Is there a different method to get the TPMS sensors to relearn? Or did I make the wrong assumption that stock FRS wheels have sensors.

I have a 2013 Prius with approximately 23000 miles on it. The TPMS randomly comes on flashes for a minute then goes Solid for about 10 minutes. On an average trip of about 100 miles or so it will go 3 or 4 times. I've taken it to Toyota to have them look at it, and they kept telling me that they couldn't find anything wrong and it has probably has something to do either with my tire pressure or my tire tread. I just did my 20K service appointment and they tried to tell me the same thing. after going back and forth with the maintenance tech, he finally admitted that the only hook up the car to the diagnostic machine when the light is actually on. After back and forth discussion I finally convince the maintenance tech to keep the car and drive it for a distance so they can see the light come on. The manual says if the TPMS starts flashing to have it looked at. But the problem is that the dealer won't work on it unless the light is actually on which is next to impossible since I'm always on the road when it happens. Has this TPMS issue ever happened to any other Prius owner?

So my understanding is that the Gen II does not have a warning light that you have left your headlights on because they lights have an auto off after 30 seconds? Well one night in a rush I left my lights on for about an hour (they did not turn off) and I came out to a dead battery. I guess my question is: Do I have a warning beep that is broke? Or is my auto off feature broke?

Last night the TPMS light came on on my month old 2010 Prius. I checked all the tire pressures and they we @ 38 rear and 40 front.
TPMS light went off after 4-5 times of turning the car on/off.
What might have been the problem? Is it something I need to be concerned about?

Just got a 2010 Prius model III and discovered that there is no warning system if you turn it off and get out forgetting to turn the headlights off.
Even my 1997 car chimed if I turned it off and opened the door with the lights still on.
Also, if only the parking lights are on there is no symbol on the dash indicating that.

I tried to reset my TPMS light using the procedure in the owner's manual after installing my snow tires on the OEM wheels. Now it looks like there is no effects as the lights will just keep blinking even if i am holding the button down. Does this mean the tire shop broke one of my sensor during the install?

The other night I was driving home and my tps light came on, Wasn't sure if it fluctuated because of the weather. So I waited until the morning, checked the light and it was still on. I checked the pressure of the tires (stock) and they were all around 36, I checked the door panel and it said they should be 41. I filled them up to 41, however the light did not go off. I held the reset button and it went off and hasn't come on. It didn't blink when it came on. It popped on and was solid.

So i got my new wheels in July, disabled all the TPMS stuff via vagcom and have had no issues or lights.
Well Saturday I start my car and i have a tire pressure low warning lit up in the MFD (no TMPS light lit up just the words in the MFD)
Due to laziness i didn't check anything till today, had the warning every time i started the car
We have just started having cold nights, so I figured i check the PS anyway today and im at 22 PSI all around. Odd that i was notified with no TPMS.
I added air to 32 PSI all around and the warning stayed on until i left the car for about 30 min then the warning was gone.

Having issues with headlights burning out in their 2010 Prius??? I had my bulbs replaced at 49,000 miles and they burned out again before 55,000 miles. They both burned out within two/three days of each other. I took it into the dealership and they weren't useful at all....

We are newer to hybrids. We purchased a used 2012 prius approximately 1 year ago. Within the past year, we have replaced the headlights approximately 6 times. Last month we replaced both front lights and tonight, out of nowhere 3 lights burnt out (both headlights and 1 bright light). It was dark outside and we live in a rural area so we had to drive 90 miles with 1 bright and the 2 day time lamps.
We maybe have changed bulbs in other vehicles once every couple of years and this is a monthly thing with our Prius. They aren't cheap so it's frustrating. My husband has been changing the bulbs and he does not touch the glass.
