Prius (2010-12) :: 2011 - Rain Water Entering Into Engine Compartment?
Feb 17, 2011
i have a 2011 prius II, and i noticed that rain water is leaking into the engine compartment. after i look at the hood design and how it closes, it was very obvious to me that water will leak into the engine compartment by design. i found this prius V picture online (i think it is very similar if not identical to my prius II). the blue pointers indicate holes and gaps where water can leak in, and the read circle indicates where water end up.
i have owned 2 other cars before this one, and i have never had rain water leak into engine compartment. do i have to worry about this?

My 2011 Prius plus made a growling noise from the front right engine compartment area the other day. Yesterday as I drove it to work...it stopped growling and the A/C stopped blowing cool air. The volume of air from the vents is the same, just no A/C.

OK, I've been reading a lot about this problem occurring in the pre 2010 prius where there is a crack around the hatch that fills the 12V battery well with water. About a month ago, I started getting a whiff of something rotting. A mix of the dead smell and rotting fruit. I was certain one of my kids left some food in the car or something got in the HVAC vent. As time has gone by, the odor has changed to more of a rotting leaves kind of smell.
I got out my shopvac and a snake camera. I went through the HVAC system and found that the filter was pulled back a bit. I replaced it on the spot. I found a few leaves and dust and that was it. The air coming from the vents from the outside smells clean. There were lots of wet leaves in the engine bay, but it wasn't the problem.
I started tearing apart the trunk because sometimes stuff spills into the tire well. I found the spare tire had turned brown on the tread.
I opened the battery compartment and found about an inch of standing milky white water. The kicker here is that the water didn't seem to smell that bad! I dried it all up and bleached the metal to kill any mold that might be in the residue...but the odor remains. The car smells awful!
I have torn apart the back of the car but I cannot find the source of the leak. I actually think it was from the car wash or going through a puddle and water got in the rear vent. The battery fender vent vanes were flapping with gusts of wind today, but even after a heavy rainstorm no new water has gotten in.
The car was hit in the parking lot and the rear fender moved about an 1/8th of an inch from the bumper, but there are no obvious signs of water entry anywhere... in fact, I was even suspicious that it might have come from the battery itself, but I didn't touch it (used paper towels on a snake to dry it up under there). I didn't think to try baking soda to see if it was an acid, which makes bleach pretty stupid to use...but I didn't see any foaming.
TL;DR Found water in my 12V battery compartment. My car smells bad. Cleaning out water did not improve smell. Nothing in HVAC system, it is only clean air source in car. No signs of water ingress above 12v battery well. After rainstorm, no additional water found in battery well. Fender vent flaps in gusty wind, but still no new water.

I usually washed my previous car's engine compartments with a hand nozzle at a coin-op car wash. I would do it a couple times a year so dust and grease never built up to the point of ever needing deep degreasing.
I looked at the engine compartment of the GENIII Prius and see that there seem to be a lot of exposed orange (high voltage?) wires that would be better off covered with some kind of plastic engine cover near the driver's side. It looks naked and some of the orange wires look like they have bare wires exposed on the outside of the tubing where it connects with clamps nearer to the front of the car. I thought my car must be missing the engine cover, but I found pics online that are the same.

recently after an oil change from Toyota dealership, I notice a wire is unplugged behind the passenger’s side headlight! The headlight, the signal light and the high beam, everything works fine.
Is this wire supposed to be open for all 3rd Gen Prius? If yes, what is the purpose for this wire? Where does this connect too?

I was looking around under the hood and noticed a plastic T with two rubber hoses attached, and one end of the T open with no hose. This is on the drivers side in the engine compartment toward the fire wall. Why would this not have a hose on it or at least some type of filter?

I have a 2013 Prius II with 35,000 miles we bought certified used from a dealer 1 year ago. When I turn the AC on, there is sometimes a louder than normal noise from the front right of the engine compartment area. Not right near the surface - seems to be coming from a little deeper in the engine compartment. If it is present, it starts when AC is turned on and stops a half second after the AC is turned off. Can't get it to repeat for dealer service tech yet (of course). I recorded the sound and played it for the tech who told me to check pink coolant levels in both reservoirs and then bring in to dealer. Thought it could be a dry or malfunctioning pump of some kind? Today I smelled a slight burning smell when the AC was turned on. No check engine light, AC seems to be working fine. My wife thinks the noise may have also been there when the heat was turned on but I cannot verify.

I searched but did not find a post about entering diagnostic mode of Prius 2010. Is that possible at all?

Is it normal to have water on the door sill whenever it rains? Driver side. Passenger side haven't noticed any yet. Basically the black step cover which has Elantra on it is soaked whenever it rains.

To install my FLIR system I need a 12V power supply, ideally switched with my Gen III's ignition switch. Where in the engine compartment can I find that?

I got a braking issue today and I'm not able to drive my car anymore. I have a 2010 Prius with a continuous beeping sound, ABS and warning lights ON. I can hear a small sound (pulsing, cranking, vibrating) in the engine compartment after the hybrid system is started. I guess this is the actuator.

Just changed out my 12v battery in my 2008 Prius, I found water in the battery compartment. There have been heavy rains this past weekend but it should not have entered the car.

I currently own a 2002 Hyundai sonata that was purchased brand new I have mostly kept up with the general maintenance spark plugs, air filters, oil changes, etc. but have been lenient on some of the less noticeable things such as belts background history: my car's alternator has tested fine at multiple places (Walmart and advance auto parts) but when I had tested it, it had only produced around 30 amps when it was built to producing about 90, i assume this is because of a bad diode.
I thought i could just use it until it completely died (despite the fact that it could harm my battery) because I'm still in school and cant afford a lot at the moment, but last night when I was driving home (it was wet out with deep puddles) and I drove through a rather deep puddle with a lot of water getting into the engine compartment. (i have driven this car through many puddles some making a much larger splash, with no problems what so ever.) shortly after I left for work and my batter light was on, I tried different things like turning the AC on high to see if they worked better at high revaluations to find out whether it was the battery or the alternator, as it turns out the fan maintained a constant speed and after work my car started.
I got about 20 feet and it died, my Friend came to charge my car but when he jumped me, the alternator started working again even though not 30 minutes ago it was not, the same thing happened to me today (same puddle same rout) the alternator didn't work going to work and it miraculously did when i went home my alternator is obviously bad and needs to be changed, but is it the alternator causing this problem, or something else?

I have a 2011 RX350 and recently noticed rattling sound coming from inside the glove compartment.
I think it comes from the plastic cover of the aircon filter at the back of the glove compartment. This cover seems bit loose even when installed back properly and the vibration (especially when driving over uneven roads) is causing the rattling sound.
I know it's a minor problem but the rattling sound can get irritating at times. My temporary fix is to push back the heavy owner's manual on that cover to prevent vibration.

I bought a 2011 VW golf TDI back in August. I current have 12,000 miles. I got my 10k oil change at the beginning of Dec. I ask them to look at the injector recall as well. Everything seem good so far. Until today..... I was out with my girl today getting the rest of our Xmas shopping done. As we were waiting for the light to change the car started surging. Not like a sensor surging but a little surging. I thought it was doing just its thing and it would stop. We pulled in to where we shop and did our thing and headed back out.
Again it started to surge. 5 mins later we pulled into our driveway and started to smell a bad odor coming from the engine compartment. Really bad that she could smell it from inside her side of the car. I can't describe the smell. Maybe electrical not sure. We let it cool down and now I'm about to check out. I have to go to work tomorrow and I'm not if I should drive it or not. I drive 158 miles a day for work.

I have a 2011 RAV4 with 122,000 miles. For the last few months I have heard a fluttering noise coming from the engine compartment, usually at in-town speeds when I step on the accelerator gently, for example to maintain speed on an incline.What could this be?

I purchased a brand new 2014 Sonata Limited 2 months ago and took it to the local dealer last night for two issues.
The first issue was small rust spots on the sillplate and the second is a very slight clicking noise I hear from the engine compartment now when I turn the temperature dial.
The dealer just called and said that the clicking is "normal". The car didn't do it for the first two months.

For the last couple of days I have noticed that I have water dripping from the engine area of my after I park or stop. The dripping appears to stop after some duration (usually don't wait to how long it persists) but I don't recall seeing this the earlier in my ownership (first 12 months of owning 2010 Prius). It clearly appears to be water as it has no color or scent and when it dries, it leaves nothing behind. The only change that comes to mind is that I have been using the front defroster which I did not use before. It is not due to using the air conditioning, as I don't use it during the AC during the winter months at all.

It's been snowing for a couple hours now and on the way home I stopped to get gas. When I popped the hood to add some windshield washer, I noticed that there was quite a bit of snow in the engine compartment, especially in the battery area and on the other side of the engine bay as well...When I arrived home, I checked my girlfriend's 2012 Accent that hasn't been moving today and there is snow as well... Is this normal that the snow gets in there so easily???

Looking for some input on a recent "hissing" noise coming from eng compartment. It's only noticeable during initial acceleration, and sometimes at the beginning of gear changes. I am assuming its tubo and/or exhaust related, as I've noticed a strong exhaust odor in the cab as well. I wasn't under load when the problem started but i was under rapid acceleration. Not noticing any fluids or oils leaking. No warning lights have tripped, as of yet.

So I just took my 2010 Camry xle-4 in today for brakes and a squealing noise coming from the engine compartment, 76,000 on the odometer. Thought they were going to tell me one of the two belts needed to be replaced and to my surprise they tell me it is the transmission. If you put it in park the noise is gone. I have the 100,000 Toyota backed extended warranty. the tech stated what I did not know until today - sealed transmission. They had to requested an adjuster (warranty requirement) to come out and look at the vehicle prior to ordering a new transmission - no repair option. Vehicle shifts with no issues, drives fine.
