Prius (2004-09) :: New 2007 - Faint Pop When Reaching About 70 MPH
Jun 8, 2013
I got into a situation on the expressway last night where I had to floor it from a dead stop and keep it floored. I was reaching about 70 MPH when I heard a faint "pop". The exclamation point came on, the check engine light came on and the car immediately started slowing down. I switched to the screen where it shows if the motor is running and it wasn't. I thought I blew the engine. I got to an exit on battery only and shut it down. Opened the hood and couldn't see anything out of the ordinary and no oil under the car either. Also checked the oil and it was fine.
I got back in, tried it and the motor started but the exclamation point and check engine light are still on. Now I'm scared of it.
It's got 110,000 miles on it and bought it used.

Our 07 RX350 has 47,000 miles and I just starting to hear (I think from the front) a faint rattling noise while driving. It's hard to describe but it sort of sounds like what you might expect if an empty plastic bottle was slowly bumping around in a plastic box. It is not a metal on metal type of noise. The shocks/struts appears to pass the old bounce test and the car does not seem to display any of the handling issues you get when you have worn shocks/struts.
I also checked the upper engine compartment to see if any plastic shrouds or covers were loose - they weren't.

In my 2009 standard prius, the back up camera often, maybe 50% of the time, is just black. It has some scrolling look, and sometimes i can see a faint image of whats there. The warning text on the screen is still there, and I am positive the is plenty of light, and nothing blocking the camera.
Its almost as if the TV rabbit ears need some adjustment. Flickery images, images literally scrolling left to right, etc. Other times, its perfect. Where do i start? loose wires somewhere?

I first noted a very faint jack hammer type sound from center of bottom of car last week-noticed it once or twice while driving, but then it continued, a little louder, and even continued when I turned the car off for about 5 minutes. Same thing happened when I drove to work the next day, and when I went to get in my car after work, it was still doing it-I think the noise must have lasted all day. Took it to the dealer and he heard it the night I dropped it off but nothing the next day when warranty inspector came out. The service guy did tell me he captured it on the computer read out and it had something to do with the brakes or ?ABS system. Service said they would drive car home and check it out-he got nothing on his long ride home but the next morning when the car was cold, it reproduced the problem. Inspector was due to come back out next day when car was cold, but came later when it had warmed up and did not reproduce, so will not fix it. They tell me is is safe to drive...is it?? And what the heck could this be?

I have determined that I most likely have a bad CV joint - a faint clicking sound while braking that varies with speed that happens with the car in drive, but not in neutral.
I've also found instructions here on how to remove/replace the axle, but I'm wondering if it can be done without separating the tie rod end and removing the ball joint. On other cars I've managed to do this by unbolting the strut, which allowed the hub assembly to flop out enough to be able to slide the axle out of it. Is this possible on the Prius? I have to replace my struts anyway so I was hoping to do it all at once and avoid dealing with potentially frozen suspension components.

I disabled the backup beeper in my 07. Now I have an ever so slight horn chirp that I hear. There is no consistency to the chirp, but it is a bit bothersome.

But I've noticed my cars ICE runs a lot more when parked now the temperatures are reaching 100 degrees. I would think with the engine and coolant warm it wouldn't. Even without using the AC, or set at the lowest fan speed with a high temp like 78 deg., and the battery with half or more charge.

At about 20k on my 07 I started hearing a faint whup whup whup between 35 and 50 mph's on the front driver's side area. At 60+ pretty quiet. It has gotten real loud at the present 30K. I suspected the tirers as I know the Integrities are complete junk but as a test I did a rotation and exact same noise.
I thought thats not good but found it hard to believe something else was bad as I had no vibration and no pull whatsoever in steering. Long story short I bought a new set of tires Kumho KR21's at stock size and oh crap exact same noise.

My wife's 2004 Mercury Sable broke down on the highway last night. We had it towed to the nearest Ford Dealership and are awaiting the official diagnosis. I am 99% sure it is transmission, as the engine didn't die, but zero of engines power is reaching tires in any gear.

Several times my 6 month old Prius v Three refuses to start. I've taken it to the dealer 5 times now for an array of electrical issues. I was told the keyfob wireless signal isn't reaching the Power pushbutton on the dashboard & to not ever put the keyfob near my cell phone & to put the keyfob as close to the Power pushbutton as possible.

2007 Camry, I4, 156000km ... For some time now, when i accelerate i hear this faint pinging/rattling sound which sounds like its a pulley rattling or some sort of chain that is loose. It mainly happens when i start from a complete stop and even sometimes when i press the accelerator while cruising. I hear the noise more when the windows are rolled down and it sounds like it coming from underneath/front of the car.
I have changed the accessory belt and checked all the pulleys for tightness and they seem pretty tight, no wobbliness. I have gotten a dealer to check it out, and they told me it was the flex pipe, i had it changed and still hear the noise, this was quite a while ago. Also no leaks from the water pump area.
The sound can only be heard when the car is in motion, and if i put it in park, or N and rev the car there is no sound. I have heard that it could be suspension related and i have had a mechanic check the suspension and he says he cannot see anything wrong. I even tried to run premium gas in the car to rule out engine pinging, and sure enough the noise persists with 91 octane gas.
Could it be related to transmission? I do a fluid drain and fill every 30,000km. And the fluid always looks new and does not smell burnt. How I can get to the bottom of this noise?

I have a 2010 LS 460 Sport and recently noticed that there is a faint water sound coming from behind the glove box every time I accelerate from standstill and sometimes when the car is idle and the A/C is on. My initial thinking was that it is some sort of a clog in the A/C drain, and that's what I told my service supervisor at the most recent service at a Lexus dealership. They said that they could not find anything except for a bit of debris in the A/C drain, which they blew out, however the noise is still there. The best way that I can describe the noise is that it's similar to a noise that a rainstick makes.

I first noticed this recently as my wife was pulling out of the driveway into the street... The car wasn't cold, as it had been running for a bit over 5 minutes, warming up. My driveway slopes a bit towards the street and also has a dip/hump at the end of it. As she pulled out in R from P, I heard a thump. I also hear a noise which sounds like the brakes engaging. So in order, brakes engaging, shift from P to R, the thump then as it backs up and turns into the street, there's a slight, faint grind noise.
As the car stops to go from R to D, it thumps again. But as it goes into drive and pulls away..smooth as butter and quiet. I've heard and read that it's possible motor mounts. I'm wondering if the light grinding is the actuator...or perhaps dried out bushings in the control arms... Also read the possibility of the trans going bad, which I highly doubt, but who knows. My plan is to call Lexus in the morning and see if I can be squeezed in.

yesterday I heard a faint rattle coming from under the hood while the a/c was on, when I had my son turn it off, it went away. Right now it's barely noticeable, but I don't want it to turn into something major. I own a '08 ES with 88,000 miles and all my service is done at the dealership.

I have some FAINT clicking noise at the rear of the 08 LS460 and I'm thinking it's rear bearing going out..but not sure...what exactly does bearing failure sounds like? I hear this SOFT clicking noise from (more likely) the right rear. The noise is very faint and I have to roll down the window to actually hear it.
If I move through the neighborhood at about 15-20 mph, I hear this clicking faint clicking sounds..and if I speed up a little, the clicking noise increases (in frequency, not loudness). When I go faster like on freeway or normal road, I can't hear it anymore. Probably clicking too fast or not as loud at that speed. With windows up, I can't hear it at all.
Is this has to do with rear bearing going out on me or possibly something else? Any recommendation where I can start looking at? Is it brake pads? The car is 35K miles but since it's 08, unfortunately it's out of basic warranty (time). Is this covered under powertrain?

I have been experiencing a slight issue with my 07 Sonata V6 lately. When I am accelerating, most commonly when already at speed around 80 to 90 km/h, I would hear this 2-3 ticks / clicks when I press lightly or moderately on the accelerator pedal. The car would accelerate fine without any further noises. When I release the pedal, the car slows down a bit, and I press on the pedal again, then the same sound re-appears.

My navigation map display is very faint and cannot be seen in daylight. I've fooled with brightness & contrast controls for the display, but none effect the map.

During around town driving I am experiencing a faint high pitch whine when braking. This sound is not mechanical, but more electrical coming from the dash-engine area. It is very noticeable when slowing between 40 mph to 20mph.

I had my Prius for almost 4 years and I'm used to all the hybrid noises: brake pump after opening the door, emission control pump hours after driving, high pitched inverter noise in EV, etc. This is different. Very faint and I only noticed it because I opened the hood right after driving. The car was completely off, but there was some small electric motor activated somewhere inside the engine. Is this electric coolant pump?

I've had my Prius 2012 3rd Gen Pckg 2 for about 1 month and love it. I've noticed that when it is quiet i can here a very light noise when turning the wheel and the power steering motor is working. It's a very faint sound resembling shhhhhh. The sound could just be the normal power steering sound but wanted to confirm.

I have a 2005 RX330, 90k miles on it. It's been running fine until last night.
Out to dinner last night, when I go back to the car, I turn the ignition key and get nothing.
So the car doesn't crank at all. No clicking either. There's a faint hum. All lights, radio, power windows, seat work. I tested the battery and it came in at 12.48v.
I'm thinking maybe the starter. But since it's a pia to get to it, i wanted to see if I should be checking something else first before i invest the time getting to it.
