Prius (2004-09) :: Noise When Driving On Freeway Noticeable At About 40mph
Sep 8, 2013
I've got a 2007 Touring with 40k miles on it. Never had any issues until about 2k miles ago, when we started noticing noise while driving on the freeway. The higher the speed, the louder the noise. It starts to be noticeable at about 40mph and gets really annoying at 65 - 75mph. It seemed to come from the RH-side, and the dealer was quick to blame it on out-of-alignment tires. Dealer 'investigation' was about 2k miles ago.
We've changed and aligned the tires this week; alignment on all four corners was almost within tolerances (off by a small amount). I've also changed the oil, since it was due.
Nevertheless, the noise is still there; now it seems to have 'moved' directly in front of the driver. What could it be?

I was sure it was a wheel bearing I'm at 198k miles. I replaced all the wheel bearings in the car and the noise still persists. The old bearings were definitely in need of replacement so I'm fine with that.
Neighbor mentioned my rotors looked warped and they may be vibrating the calipers but the they don't seem to vibrate harder under heavy braking. There's no vibration through the steering wheel.
When I did the front bearings the CV boots are still holding up. I kinda busted some of the dry and cracking boots around the tie rods and ball joints but that's for another day.
Anyways, I run winter tires all year round being in snow belt and they are cheaper. Wear is worse on the front tires outside edges from cornering and I'm gonna replace and go for an alignment soon.
It has to be something that is spinning on the car from the noise I'm getting. Worse at higher speeds, constant variable humming.

I was on my way to work this morning when the car just stopped accelerating (or so it felt), all the dash lights came on, I pulled over to the side of the freeway (I was very lucky). Radio and a/c were still working. Powered off, powered on too soon a couple of times - the red triangle and check engine both came on again. Cooled my jets and gave it a few minutes, powered on and the red triangle was gone, but the check engine was still on. Drives perfectly, no problems w/either gas or hybrid engine.

2011 Camry LE with what I would call a mushy or sloppy feel to the steering. It is most noticeable at freeway speeds and requires an almost constant driver input to maintain the car in my lane with slight corrections back and forth right and left. This is fatiguing on long drives. It feels like there is too much power steering assist at higher speeds, although an independent mechanic said he didn't think it has variable assist power steering. There is no pulling in one direction. Alignment has been checked and it's ok, and tires are balanced and properly inflated.
Strong wind or large trucks passing me cause me to struggle to maintain the car in it's lane. Toyota dealer mechanics and the Toyota rep checked it and gave me the "drives as designed" answer and that there is nothing wrong with it. I had an independent mechanic look it over and he said there is nothing wrong and that there is nothing that can be done to change the feel of the steering. It is hydraulic steering and not the electronic power steering. I have test driven other Camrys as well as Corollas and other makes of cars and they all drive with a more sure feel to the steering and I just want my Camry to drive like that.

I was driving on the freeway in houston yesterday and it was about 30 degrees. The low temperature light was on... Does it make a difference when it is cold? Why would there be a light to tell u that it is cold outside?
Anyways as I was driving on the freeway the red triangle with an exclamation mark came on and disappeared. Then a minute later it went on again and on the navi screen shows high coolant temperature symbol on it. But then it would turn off right away too so is this normal because I was kind of slowing down on the freeway and the book did say something but I don't think it was an excessive speed or anything.

I was driving on the freeway(70mph), when a loud pop noise (sound of a blown tire.) Felt like a wheel bearing seized up then felt rough on the road. Got off the freeway and everything looked normal from the outside. No smell/smoke. While driving home on the back roads, i was hearing a rattle from the trunk area.
Lifted the car and noticed a little bit of fluid on the front of the differential. Didn't find any leaks or puddles. Took the fuse out for the haldex, and drove it around, still feels the same but still hear the rattle. Hoping its not the differential but haven't drained any fluid yet.
Ok, well never mind. brake system locked up on me.

I recently replaced the front wheel well liner on the passenger side. The old one was shredded and I figured it had come loose. I put a new one in and made sure all fasteners are used (bought new fasteners). Still during some freeway driving the liner did not stay behind the lip of the front bumper and rubbed a small hole in it from the tire. Any way to prevent it?

I've got an 06 F150 5.4, and its making some noise. It has a constant tapping noise that can be more easily heard when I'm attempting to order my fries at the drive thru. The issue is, I'm having some difficulty identifying it. The tapping noise is very noticeable at idle, and becomes sickeningly loud at approximately 1000 rpm (in neutral) and almost disappears after 1200 rpm. i know for sure that it is not the normal noisy injectors, and it sounds too distinct to be a lash adjuster or lifter. I have not been around a truck with bad cam phasers to know what it sounds like. I don't want to start throwing parts at it until i know where to look.

Yesterday while traveling on the freeway and using cruise control my 2016 Prius beeped loudly, displayed the message "Cruise Control is Unavailable" and dropped me out of cruise. I turned cruise off and back on, and got the same message. There's also an orange indicator light blinking that looks like a car hitting another car, and the "Cruise Control is Unavailable" message now displays on the info panel every ten seconds*. Collision prevention is also unavailable.
Was this something I did wrong? Is there a way to get cruise control and collision prevention back?

It seems to me my Prius 2007 decelerates noticeably when I take my foot off the accelerator. It's noticeable but not even near the level of the engine braking in B mode. The change seems to have happened since my last service but the I won't swear to it, and the dealer says there hasn't been a software change.

I always apply my parking brake whether im parked on an incline or not. Sometimes if I disengage the parking brake, and set my car in Drive on a flat surface, my car does not advance (I'm not pressing the gas). This tells me that my parking brake is sticking! If I apply the gas slowly, I hear the brakes "clunk" off and I finally get going.

I have a 1990 Lincoln Mark VII, black on black, basically one owner, excellent condition... except one problem. While driving the car my speed dropped to 40mph, while my RPMs rose to 4000. Upon checking I found the plastic clip, which holds the linkage from the transmission to the accelerator had snapped. I replaced the part and still have the same problem...is my transmission smoked or is there an adjustment?

Yesterday while driving on the freeway in EV mode, my PIP (one of the first delivered to the states) flashed the "Check Hybrid System - Stop the vehicle in a safe place" message. I was near my house so I just went home. My SG2 showed code P0C3E, which is apparently an inverter over temperature code.
Took it to the dealer this morning and they just informed me that the car needs a new inverter, but no other details… "internal fault" is what he said.
While googling, i found this recall notice:
Green Car Congress: Toyota recalling about 701,000 Gen 3 Prius vehicles in US over software issue in inverter assembly
that doesn't talk specifically about the PIP and implies that it is a software problem, but goes on to say if the car is in a fault condition the inverter will be replaced. of course, it's possible that a software problem leads to hardware damage.

Right now I am seeing roughly 41 MPG and that is after changing the spark plugs with brand new NGK Iridium's, Air intake filter and did an oil change since it was due for one. I have driven the car roughly 2,500 miles since all of this stuff was done and it just seemed to continue to drop to the 41 MPG mark.
What I have noticed though is that when the motor turns off it shudders and the when it restarts while the car is in park the car will roll back and forth slightly. I have also noticed that the car seems to struggle to get up to the posted speed while climbing an incline and also while the car idles in park or at a complete stop there seems to be a bit of a miss fire. Could that be caused by a bad coil? Because I have tried everything short of taking it to the dealer which I really do not want to do again and be told there is nothing wrong with it when I know there is.

I just bought a 2007 Prius a couple of days ago and noticed on my drive home the first day after purchase that the A/C got hot when I was accelerating onto the freeway and remained hot for a couple of minutes after that. I turned it off then turned it back on, and it blew cold air for a couple of minutes, then settled on a "cool-but-not-cold" middle ground. When I test drove the vehicle, I ran the A/C, but since it wasn't overly warm, I didn't notice that the car struggles to reach "cold" and mostly blows only "cool" air.

I have a 2010 Prius no frills model with 5500 miles on it. I've started hearing a noise that sounds like loud burst of radio static. I hear it with the radio off or on. It's very intermittent, but seems to occur only at freeway speeds. Seems to be coming from underneath the shifter or underneath the dash in the same area.
