Prius (Gen 2) :: 2007 - Grinding Noise When Accelerate
I have noticed the past months (maybe for a while, probably picked it up just a few weeks ago) when I accelerate, I hear this grinding noise, but once I let go of the gas pedal, and slowly get back on it, the grinding noise goes away. To give a better example, when I step on the gas as I normally do, this grinding noise (it is coming from the front, I feel like it is coming from the passenger side, can't confirm 100%) but once I let go of the gas pedal, it goes away. The noise itself starts when I start picking up speed from a full stop, so when I am going at around 0-30 MPH I hear the noise, after that, I honestly can't tell (road noise may be blocking it off, not sure).
I went around the car and tires, and everything looks fine, I have no error codes thrown at me, thus, I am posting here as I really want to fix this issue as it is really bugging me. (It doesn't impact my drive, but that grinding noise is definitely not the normal sounds of a Prius).
Lexus GX 2004-09 :: 2007 GX470 - Noise Like A Slight Belt Slip When Engine Downshift To Accelerate
Few weeks ago I bought my first Lexus, an '07 GX 470. It has roughly 75,000 miles on it, 2 previous owners before me. Anyway, I hear a noise sometimes which either sounds like a slight belt slip or fuel being pumped into the injectors when I give it a good amount of gas and the engine downshifts to accelerate. I had the dealer replace the drive belt(serpentine belt) because of 2 reasons, it needed to be replaced and I thought that could be the problem(I did not have to pay for it since I have had some problems with the Lexus dealership I bought it from, they did it as a "goodwill" gesture, that's a story for another thread) and inspect the tensioner and pulleys, they said the pulleys and tensioner were in good working order.
I drove the GX home tonight after said replacement, and I still noticed the same noise. The best I can describe it is like I said above, a slight belt slipping noise or it could also be described I guess as fuel being injected under acceleration as soon as the trans downshifts to accelerate. I am just curious if this is normal for this engine or do I have a possible problem? It's covered under the Lexus used car warranty for another 5 months so if there is something wrong, obviously I would like it fixed under warranty if something is wrong. One thing I should probably mention is, the noise is semi quiet and I guess the average person might not even notice it.
Prius (2004-09) :: Won't Accelerate Uphill?
I just bought this car last night from a guy with a dealer license. The car was used, so he sold it with an "as-is" statement. I've read there is a 2 day law to return used cars, but he never gave me this option.
I test drove the car but nothing appeared wrong except the heater did not blow hot, thought the car wasn't warmed up. May be unrelated. Anyways, driving on the interstate I noticed he pulled the battery before selling it to clear the trip memory, and all of that information. So I asked him and he said it was for a small part he installed (he showed me, it looks like a thermostat of some kind with a hose coming off of it, he did not know the name).

Today, we got a flat tire, so went to put spare on. The jack bent when we jacket it up..so had to borrow jack from neighbor. Once we got the spare on, it made a funny noise..on the way home, it wouldn't drive over 22 MPH, and once we replaced the original tire (got a new one/fixed), the car started to accelerate and brake itself!! It was definitely not normal. And there was no resistance to the pedal or floor mat interference.
I believe it was a computer problem? Anyways, when you hit the brake (cause it was going so fast) you could hear the engine strain as it groaned to a stop. Got the car home and in the garage for the night..That was work in itself, not driving it through the wall! Arranged to get the Prius towed to Toyota in the morning..see what they can do. It's intermittent when it does this, and very weird.
Prius (Gen 2) :: 2004 Won't Accelerate And Shuts Down After One Hour Of Freeway Speed
After one hour of freeway speed (60-80) the car slows down to a stop and red !triangle! light comes on. After coasting to the shoulder and waiting 10 minutes, car restarts. This has happened 3 times in the last two months (very frightening, but luckily it was light traffic). Dealer says 'no codes' and that there is nothing to fix!!!! What now? I can't drive a car that could lose power at any moment. Big safety issue....

I may be worrying over nothing but lately when I brake or accelerate I hear a grinding noise on my radio. I listen to AM. With my other vehicle it usually meant there was a problem somewhere.

I got a problem this morning my car was juddering when I tried to accelerate my Toyota Prius 2004. When it's over 40MPH the car runs smoothly. After few hours it increased and now its jerking and juddering big time. Also when my car is moving the "Traction Control light" flashed even on dry tar roads. When I try to run from the battery the car runs smoothly at any speed. Also on neutral, the car idles fine and no juddering. Since few months I felt like the clutch plates are slipping and engine revs high than normal only when it's running on gas. Seems to be okay on battery.

I just purchased a used 2006 package 3 with 66500 miles on it. Drove it to work today and the car started sputtering/shuddering when i was accelerating onto the highway. The check engine line came on so I took it to the dealership. Turns out it was a bad sensor.
When they fixed the bad sensor, the mechanic told me that its normal to feel a slight stuttering when the gas engine kicks in or off which seems to be confirmed by other members here.
Prius (2004-09) :: Traction Control Warning Light Comes On And Car Will Barely Accelerate?
I have a 2008 with 81000 miles and new tires. On clean dry roads when I hit 60 mph the traction control warning light comes on and car will barely accelerate. Slow down a couple mph and car runs fine. What is wrong?
View 5 RepliesPrius (2004-09) :: VCS / ABS And Yellow Exclamation Sign Came On / Noise When Accelerate And Shaking
We bought yesterday a 2004 Prius with 73K miles. This was (unfortunately) a private sale. When my husband drove back home with the car, the VCS, ABS and ((!)) yellow came on when he reached 60mph and above. He also noticed a lot of noise when accelerating and the car was shaking. The noise is also there at low speed and when accelerating it is so bad and feels like something is rubbing?
This morning, we decided to try the tire pressure to see if this could be the issue. After correcting tire pressure (it was actually very bad), the lights went off and we decided to try it on the motorway. The car was noisy to start off but as soon as we hit the motorway, the sound was getting worse and worse. I could feel my passenger seat shaking under me and the 3 lights (VCS, ABS and ((!))) came back on and stayed on until we got home.
What was the issue in the end? We have spent all our savings in this car and can't really afford expensive repairs few days after buying it. We are just gutted. Oh and we have a 2011 Auris Hybrid with 15K that runs superb. My dad owns a Prius too and so I can tell the noise is just not normal- at the same time, perhaps a 10 yo Prius is supposed to do this noise?
Prius (2004-09) :: Hybrid Battery Runs Flat Every Morning - No Electric Power To Accelerate
It's been like that for a a while now. Every morning the hybrid battery would run down to last bar. When I start the car it would be 3/4 full and it would keep draining even though I'm on flat road.
The overall mileage has not changed much but its annoying with the battery goes to last bar and there's no electric power to accelerate.
Camry :: 2007 V6 SE - Wheel Hop When Accelerate Faster
I have a 07' V6 SE and have a nasty wheel hop. Went to the track and ran 15.0@95mph all night because I can't accelerate faster without the nasty wheel hop (temp was 90 with lot of humidity). I would like to go to the track again, but before start making some mods (intake & complete exhaust) I want to get rid of the excessive wheel hop.

I was installing a new engine mount the one on the tranny and one of my jack stands failed on me, luckily I wasn't under the car. I always put a tire under the car just in case and it worked for me, but now whenever I accelerate I have a humming/whining noise. Can this be the transmission? This is on the 07 Camry 4 Cylinder.

I have a 2007 Toyota Camry SE V6 with 201,000 miles on it. My problem is that when the vehicle is idling it is smooth as can be, but when I begin to accelerate or even floor the gas pedal, the car begins to violent shake and feels like it is about to fall apart. I just had new front and rear brake pads and rotors put on yesterday. The tires have about 6,000 miles on them and does not need to be aligned.

My 2007, Honda Accord, 6-speed manual, 6 cylinder EX Coupe vibrates when I accelerate between the speeds of approx. 50-65 mph and then smooths out above that speed. Slightly higher when going uphill.
It only happens when accelerating and not if I'm just cruising without applying the power. My wheels and tires have been checked for balance and are in good shape. No bent rims, tires are in balance.
Toyota - 4Runner :: 2007 - Shaking When Slowly Accelerate Between 30 And 40 Mph
In my 4 runner when I slowly accelerate between 30 and 40 mph just as I can hear the car about to shift gear the car begins to shake when I than accelerate the shaking stops. Brought it to a shop and they changed a spark plug and coil they say was mis firing, but I pick the car up and the problem is still there. Their diagnostic shows no problems, yet the shaking is still there when slowly accelerating between 30-40, no check engine light has ever come on. While it shakes if I shift the car from D to 4 the shaking stops, and if I speed hard through 30- 40 it doesn't shake, just when I slowly accelerate.
View 5 RepliesToyota - Camry :: 2007 Car Suddenly Would Not Accelerate Above 20 Mph Or 2000 Rpm
2007 Toyota Camry, 4 cyl, automatic transmission, 147k miles. Was driving ab 60mph and slowing down as I approached a red light. Light turned green but car suddenly would not accelerate above about 20mph or 2000 rpm - ran fine as long as I stayed under 20, but when I tried to accelerate beyond that it started lurching like crazy and wouldn't accelerate. Pulled into a gas station and let it idle for a few mins while I checked the transmission fluid (has had a slow leak but I have been staying pretty on top of the fluid levels). Color and smell of the fluid was fine, but level was just a little low so I added some more fluid and let it cycle thru for a few minutes. Managed to get it home by staying under 20mph. Turned it off and basically ignored it for about 10 days due to being swamped at work. Went to start it up last night and the engine cranks but won't turn over and start. Lights, etc. all work. What gives? Praying this is not a transmission issue.
