Prius (2004-09) :: 2006 - Intermittent Popping Sound And Reduced Gas Mileage
Jul 2, 2012
She was driving and she turned onto another road this morning and the Prius started making a popping noise which lasted about 30 seconds. She normally averages about 42/43 mpg but it is down to 37 mpg. She said she has noticed since yesterday the Prius did not drive the same (I am assuming she means the power). The Prius is a 2006 with about 105,000 miles on it. Nothing has ever been done to it since we purchased it new in 2006 except oil and tires.

I bought a used 2008 Sonata GLS with 65K miles 2 years ago. It's been a great car so far. For the first 25K miles that I drove it, it had good pickup and got ~30 MPG for my highway driving. In the last ~5K miles, the fuel mileage has dropped to 25MPG highway and it has some hesitation when accelerating, especially on lower RPM's. I changed the spark plugs with NGK Iridium, but it is still having the issue. What to check?
Some possibilities: ignition coils, sensors, timing belt, etc?

After air filter change our 2004 Honda Pilot mileage was reduced by 50% (got about 11 mpg on interstate and we used to get 24 mpg). I checked tire pressure and they were low, so I inflated them. I have a code reader, and the car is showing no error codes.

My headlights on my 2006 are hazy and yellow and the light output is reduced. I tried some plastic headlight cleaner stuff but it was clear for like a month, and now it looks even worse than before.

We gave the Prius a good workout in the rain for the first time today. Central Florida has been having serious amounts of heavy rain, creating water covered roads in our area. Normally the digital fuel mileage display shows around 55 MPG for most of our driving. However today it dropped to the upper forties very quickly.
We were running the wipers on continuous (low and med speeds), the AC (defrost) was running to keep the condensation off the windows, and the headlights were on. I wonder if the extra resistance of the water on the road also had an effect on the fuel mileage.
Even though we hit some fairly deep water and created large amounts of splash, the car tracked straight, the brakes worked well, and the power was totally uninterrupted. Other than the poor fuel milage we were impressed.

I have an 06 Prius that I have had for about a year or more now. When I bought it, it needed a transaxle. I replaced that and have been driving it since. I have this problem that seems to be getting worse. When I push the brakes the car will make a popping noise, and it seems to be getting more frequent. I do not get any noticeable noises when turning or just driving normally.
The noise is quite noticeable, when I am in a parking lot and hit the brakes next to someone, people will give me the look like "what's wrong with your car". I am not positive where this noise is coming from, but my best guess is that it is coming from the right side. The popping seems like something is bound up and then releasing. I can also replicate the noise some times when I initially accelerate. My best guess is that it is being caused from the engine/trans weight shifting, but I am not sure a motor mount can make the popping noise I am getting.

About a year and a half ago I moved from Chicago (500 feet above sea level) to Morelia, Mexico (6,200 feet above sea level). My gas mileage on my 2000 Ford Focus has plummeted, I used to get anywhere from 22 to 26 miles to the gallon around town in Chicago but I am lucky to get 14 or 15 here. Is it simply a function of altitude? I have a good mechanic, keep everything tuned up and in good shape.

I am a relatively new owner of a 2007 Prius and am curious about a sound I hear quite often while driving.
The sound is similar to a cd changer changing disks my package doesn't have the disk changer). It seems to happen when braking but I haven't pinned it down to one catalyst.
It seems to be a normal sound and I am not worried about it since riding in my roommates '07 Prius and heard the same sound.

In my 2006 Prius, I just started noticing this recently, but whenever I turn my steering wheel, it makes a weird noise and I can feel something going on through the steering wheel. It doesn't impede my steering, the car steers just fine... It's just an add sound, I don't want to say a cracking sound... but it kind of is? I don't know. I'll have to put a video of it up. & it doesn't matter which way I turn it, it still makes the weird sound and the intermittent vibration... I know it has E-steering and occasionally you can here the motor whirring when you turn it but this is different, it's a loud... popping noise is the word for it! Popping, and I can feel it when it pops through the steering wheel. Again, it doesn't impede the steering ability at all, but something isn't right I'm sure... Or maybe it's normal.

Our '06 has 68K on it. Last weekend I changed the front bumper (just cracked from small accident last year) and changed the oil. Used Mobil 1 5/30 and a Fram Oil Filter.
After about 125 miles of driving intermittent Red T.O.D. Always when ICE is running.
Oil level is OK - not loosing any oil. Filter and bolt on the pan are fine - no leaks.

For several months now, my 2007 Prius has been making an intermittent buzzing sound from the engine bay. When I first heard it, I thought I had hit the little lines they cut into the road to let you know you've drifted over the center line - the sound is like that, a low-pitched buzzing noise. Today, the check engine light came on as it was making that noise. I put a code reader on the car and got P1121, a bad coolant flow control valve. Wondering if the sound and the faulty control valve are just coincidental or if the valve might make that noise when it fails? And if not the valve, what the sound might be?

Just replaced the front struts last week and the upper control arms this morning. After putting everything back together I drove her around the block and noticed a horrible popping and squeaking like something was loose. I quickly limped her home and double checked that everything went back on properly and was tight. Car is the V6 with eibach's and about 103,000 miles I have drain and filled the tranny every 30-40k.
What this sound might be? It goes away once I am above about 10-15 mph and sounds like it is coming from the center underside of the car. I will also try to get a video of the sound while I am driving.

I've had an issue with my 08' for a few weeks after returning from a 1 week vacation with the car sitting on the street in NYC. The symptoms are a noise associated with poor performance of the vehicle. It accelerates slower and requires more RPM. When you take your foot off the accelerator it feels as though there is a brake on or some additional drag somewhere in the front end. It's really evident that it doesn't actually glide, but it decelerates rapidly.

2002 ... I've been getting a soft engine fault all three lights on and reduced power. This usually occurs if I accelerate hard but also happens if I take a small pot hole in the front, a little bump seems to trigger it as well. Also engine resets to normal after removing key.
It's not logging the fault as had dealer read ECU and said was not logged.

I'm experiencing a really annoying issue with my 2007 3.3L sonata. Whenever I am making a right turn (with the breaks applied), I hear a knocking or "popping" sound from the driver's side front end. It's not a single "pop", but multiple "pop"..."pop"..."pop". The noise does not occur when making a right turn without the breaks applied, not does it happen when making left turns. Also, during a right turn, if I release the breaks, the sound will immediately stop. The car only has 64k KM (about 40k miles).

I replaced my right front axle a week ago because I was getting severe popping/clicking noises. The boot was torn on the axle and I had grease all over the inside of my rim etc...
The popping/clicking sound was gone immediately after replacing the axle. Now starting yesterday, exactly one week after I replaced it I noticed the popping/clicking sound coming back. It was faint at first but started getting louder. Now today it's almost as bad as it was before I replaced the axle. I still have to get underneath and see if I can hear where it's coming from? Think the axle is bad again? It is an after market Axle, ToughOne is the brand I believe.
Just for a quick history. All four wheel bearings were replaced about two years ago. All four ball joints about a year and a half ago. I replaced the outer tie rod ends about two weeks ago.

I have a 2005 FX4 with a 5.4L. I have noticed in the past 3 months that when I mash the go pedal hard the engine misses and there is a popping sound. My gas mileage has gone down 2-3 MPG.

I have an '07 Azera and the turn signal sound is intermittent. The signals flash normally, but sometime I hear the flasher sound inside the car and sometime it is dead silent. Cannot seem to correlate it to temperature or other factors. Any way, I assume as the lights flash with no sound that either the flash or the sound is electronically generated, but cannot be like an old school mechanical flasher. What makes the flasher sound in the Azera and where is it located?

I have an '04 Suzuki Aerio, and there is a loud popping or knocking sound coming from the front of the car when I drive it. I don't seem to hear it when the car is inert (i.e. idling or traveling in a straight at a constant speed). I hear it intermittently when I accelerate/decelerate or turn. I hear it in drive and reverse. The strange thing is that it seems to go away completely when it is raining, and then come back when it stops raining and things dry out. It has been happening for a month or two. I think it has been gradually getting a bit louder. What could cause this?
