My wife has said that yesterday morning (and also a couple of weeks ago), she started the car and a constant whine came from the engine area. It went a few minutes later while she was driving.
View 9 RepliesYesterday while on an 50 mile I had much more serious whine from the engine bay for about 10 minutes, that I think was from the serpentine belt. I wasn't driving, but my driver (my gf) called and I could certianly hear it on the phone. I could hear it in the cabin, then I could hear it from outside the car. She opened the hood and said it seemed to be coming from the passenger side down by the firewall, engine side. I could hear it while driving and while she was parked and idling.
I'm not familiar with the prius engine bay yet but that area is where the fan belt is i'm guessing if its like my other fwd cars.
It was cold out. She was driving about 55 mph. She had already driven 45 miles when it started. It continued to whine like that while parked and idling, and also while driving. She started and stopped the car and it would start when the car was started. I'm sure she had the heat on the whole time so i can't tell you if it quit when the engine cut out, but i bet it would have.
Then after about 10 minutes it stopped. It started a little bit at start up and then went away. She drove home 50 miles and didn't notice it anymore. I drove it last night in 12 degree city/suburban driving/ highway for 50 miles and never had it come back.
I have recently purchased a 2007 Gen 2 Prius and sometimes it emits a very annoying squeak. It occurs when the car is stationary, with the brake pedal fully depressed. When inside the vehicle it seems to be coming from behind the glove box. When on the outside and facing the car it seems to be coming from below / behind the electric motor. I have made a recording of it with the noise in question being audible for a couple of seconds at 0:13, and then again at 0:22 until the end. It could be nothing I guess, but this is my first hybrid and I am not too sure what is perfectly normal and what is not.
View 14 RepliesMy A/C will blow cold for about 3 min. and then stop for 10 min......then cold again for 3 min.....then warm for 10 min.......what is going on ? It does this when on climate control and on A/C . I had a compressor go out about 1 1/2 yrs. ago due to a fan failing...the compressor tore apart... This is not acting like that though .
View 9 Replies2013 Prius v (wagon) Level 3: When I pull into a rest stop (“Ready” on, in “Park”) for a few hours of snooze, and the traction battery is “full” (~6 bars), it will run the AC for 60-90 minutes before the ICE starts up (at 2 bars) to recharge the battery. It recharges to 3 bars (in ~3 min) and then shuts off.
After that the ICE cycles on every 15-20 min (which is annoying) and each time it runs just long enough to charge from 2 bars to 3 bars. All of that on/off is hard to sleep through. I bought this car because it can run the AC off the battery, which it will automatically charge when low. It’s brilliant – up to a point.
Question: How do I tell the ICE to charge the traction battery from 2 bars all the way up to 6 bars again (should take ~ 15 min or so) while parked, for another whole hour+ of quiet slumber?
My daughter's 2004 Camry V6 has been hesitating when starting from a stationary position or when accelerating after slowing down. Dealer has been having hard time identifying cause but thinks it is an oxygen sensor. Had one sensor replaced last fall when light came on. Tech Rep says there are four sensors. At least one is bad but the other two sensors may also be bad. Is there really four oxygen sensors in the 2004 Camry? Would this cause the hesitation when accelerating?
View 2 RepliesI've just collected my '07 from my local Toyota garage. It was in to check out a hum/whine type sound coming from the front of the car. Turns out that the front right hand side wheel bearing is on the way out. Now the question is, would it be prudent to change the left bearing as well, when I get the right bearing sorted?
View 7 RepliesI've got a 2006 Prius - yesterday afternoon my wife and I noticed a high pitched whine coming from the front (maybe right hand side) of the car - we don't hear it until we reach about 50mph. It gets louder as we increase speed and then trails off when you step off the accelerator and can't hear it all below 48-45mph.
We bought the car new and are familiar with the various noises the car makes, but this one is new - never heard it before yesterday.
My car has 155k miles and I haven't had any previous issues with it. I noticed probably 30k miles ago the beginning of a whine sound when the car accelerates. The noise has been getting louder (it's really not that loud) but I am wondering what this could be. I want to avoid anything happening to the car and want to find out what the problem is so I can fix it.
View 6 RepliesI have a 2006 F350 6.0L Powerstroke. While towing my RV this weekend in 96 degree weather, it appeared that my transmission started to whine after several minutes of pulling some large hills. I was in tow/haul mode. It did not appear that I was loosing power however the sound was very concerning. The sound went away after leveling off, or switching out of tow/haul mode. The sound coincidentally appeared as I approached the top of the hills which ranged from 1 to 3 miles in length.
View 11 RepliesI have a 2010 Prius and need to change the Transaxle fluid. I have the Haynes repair manual, but it only shows the drain and fill plugs for the Gen II. I have found what looks like the drain plugs but am not sure of it. Fill appears to be right next to the CV axle and the drain is straight down from the CV axle. Are these the correct fill and drain plugs?
Also, this transaxle seems to have a whine to it. Whines only at kind of a neutral throttle. Throttle pressure or backing off on the throttle reduces the whine. Is this normal or what?
About 3-4 months ago, I noticed a low-pitched "roar" or whine coming from the front of my 07, especially at 35mph and above. The pitch of the sound gets higher the faster I go, but its never a high-pitched squeal or anything, just a roaring whine that has gotten somewhat more noticeable as time has gone on. 184,500 miles on the car, Goodyear Assurance tires that will probably need to be replaced fairly soon but are certainly not bald, reasonable tread left. I bought the car with just under 160K, I've put about 25K miles on the tires, but don't know the car mileage when the tires were originally installed.
I had the tires rotated during an oil change about 6 weeks ago, which made little if any difference in the sound. I asked a mechanic I know (and trust) at the non-dealer where the oil change and tire rotation was done, he said to turn slightly left and right while driving to see if the pitch changes, which may indicate a front bearing problem. There was maybe a slight pitch change in the whine when I did that, if any. He said it might be the start of a bearing problem. I also don't notice any change in the pitch or unusual behavior when making turns.
So is this a tire problem or front/rear bearing issue? I'm going to take it to the mechanic for him to test drive, would I be better served going to a dealer? Given the car mileage, it could very well be a bearing problem, it would certainly be due.
Have a moderate pitch whine in front end only when steering or turning to right. Gets louder w higher speeds but pitch is about the same. Thought it was a left front wheeling bearing. Also needed new pads and rotor. While doing the job noticed grease all over the lower ball jt. Discovered a tear in the outer axle boot. Net net replaced pads, rotor, axle hub assembly and axle complete. To my chagrin the noise has changed one bit. The noise also doesn't change when I put the car in neutral while traveling downhill. With the hope that I replaced the wrong bearing I have ordered a new one for the right passenger side. When I tried the 6-12 wheel rocking test on the right there did not appear to be any looseness.
View 5 RepliesThis evening I had an interesting hiccup happen. Out of the blue the car would not recognize any function of the key fobs (both) inside or out. Recently changed batteries in the fobs and the red LED was coming on with button presses so those weren't the issue. But as I mentioned, the car wouldn't recognize the fob for any button press or proximity for unlocking/ignition.
There have been a few times where the fob right next to my phone would throw the car off, along with a few random scenarios where I had to be right next to the car for remote lock/unlock to work. I figured this was some type of interference as all the occurrences seemed random.
Anyway, after nothing working I tried the fobs again and they worked as if nothing happened before. So, where the car possibly resets or in some way refuses to acknowledge the key fobs for a short time.
I didn't know how else to word this, but I know that the Prius has a few "stages" it goes through as it heats up to a certain temperature and whatnot...
Here's why I'm posting, in summary: I have a 2006 with 115K. When I was driving a 150 mile trip, for the first 30-45 minutes on cruise at 72mph, my mileage was very poor, much lower than average (40-42mpg). But after about 45 minutes, I slowed down for some construction area, then resumed cruising at 72mph, it jumped to about 48-49 mpg for the rest of the trip.
For the first 45 mins, it felt like it was struggling, because I could feel like the ICE rpm's were higher than normal for that speed. I even tried to gun it to 80+ and coast down, but it still felt like it was working hard. Finally, when I slowed down to 60-ish, then sped back up, it started operating normally.
My wife has recently been complaining that the AC will work for a while, but then it stops working after running for about 30 minutes. She also reports that, at that time, the air flow (blower speed?) seems to drop tremendously. I have observed the former but not the latter, so I can't say for sure that if it really drops in air flow or if it's just a matter of perception. I put my AC gauges on it and it reports the following:
Static reading is 70/100 PSI
Reading system on is 17/145 PSI
Ambient temperature is ~92 degrees humidity is 65%
Vent reading is ~77 degrees
I can see movement in the sight glass while the vehicle is running. I'd like to add a little refrigerant (if that's what it looks like it needs) just to see if we can make it through the summer. Prior to the AC problems popping up.
Yesterday my 2008 Prius with 95,000+ developed a new noise after turning it off and it has me a bit worried. I took an audio sample? Last night it occurred for like 5-10 minutes. Now today I went to turn it on and before I even pressed the power button it made another noise that I've never heard before which I didn't get on audio. It turned on fine, I let it run for a few minutes and then shut it off and the noise I got on audio occurred for several minutes. The noise comes from the driver's side by the electric motor. The clip should play in iTunes or Winamp, took it on my iPhone so its kind of low in volume.

View 2 RepliesOK, I finally resolved the bad skid control ECU, so I have no more codes relating to ABS sensors or pump actuator. Still get a C1310 when travelling at speeds over 60 for 10 minutes or so. After the car sits for a while, the idiot lights, triangle, ABS and brake lights disappear and the car runs fine. Except it has been whining at acceleration and deceleration a bit more than I remember. When I hooked up Tech stream, I got a P0A2B which is - Drive motor "A" temperature sensor circuit range/performance. Please tell me it isn't transaxle. Why does it only happen at high speeds? I can drive for 20-30 minutes around town without it triggering the dreaded red triangle.
View 4 RepliesPrius a/c start to blow hot air after driving the car for 30 min. In the next day when i start the car, it blowing cold air.
A/C starts to blow warm air if i drive the car more than 30min. look like once the engine heats up its start to blow hot air. What will be the issue?
Only twice i got the VSC and Engine Check light. but it went off after 2 days. i Took it to the auto shop and did a scan, they said its giving lots of code (codes like: C1241, U0073, U0123,U0124, U0126, U0293, U0111) and they have reset the codes. and told if you get warning lights again then they can try.
After starting the car, MFD doesn't repond to touches anywhere, the side buttons work but the touch screen doesn't respond to touches. Is this normal?
