My 2006 is having acceleration/power issues. It won't go above 35mph while being very slow accelerating. Toyota diagnosed it as needing a new battery so a new $2K battery (not rebuilt one) was installed. It still has the same problem. It seems like a problem between the electric/gas power transfer.
View 19 RepliesI recently bought a 2006 prius used with 100,000 miles and have been hearing a very disconcerning sound coming from underneath the car. It is a screechy noise that is always there, but especially when i accelerate or break going up a hill. I have had it checked out by both a dealership and an independent mechanic neither party has info what it could be, even after hours of troubleshooting, as well as showing then a video in which you can hear this awful sound.
View 4 Repliesmy 05 is giving me these mini shakes when I accelerate and slow down. I also get a little bit at highway speeds. I was walking around the truck today and I noticed that the back right tire doesn't have a weight on it. I thought this was wierd. Could a weight have fallen off thus causing the vibrations, or is this normal for one wheel to not have a weight?
View 13 RepliesWhen I am accelerating heavy and then slow down as it is engine braking i get a strange vibration. It seems to come from the drive line i just looked over the car today there is nothing loose all suspension is tight drive shaft looks good and the rubber u joint looks good too. I noticed it after I put in the resonator delete but I didn't think that it could cause it.
View 2 RepliesI purchased a 2006 Ford F-150 XLT, 5.4 3V Triton. Last Thursday my check engine light came on, so I came to this forum and found out how to retrieve the code with out a OBD. It came up as a 0301 Misfire cylinder 1-10?
I went to the dealer and they said it was cylinder one, sold me a new plug and coil pack and they installed it for a nice $$$. On my way home it started to sputter again when you give it heavy throttle, I called they told me that I should change all the plugs and Coil packs, kinda makes sense but to have all 8 plugs and coils go at once it only has 83km on it.
Ok, I have a 2006 Ford f-150 5.4L engine. it has 88000 miles on it. Here recently it has started acting up on me. It starts shaking violently when I slightly accelerate going up hills at any speed. On level ground it doesn't do it. Going down hill it doesn't do it. When stopped it doesn't idle rough.
It does this shaking when I barely press the gas. When it starts I either let off the gas or I push the gas to the floor and it stops. What is going on? This is the first Ford I have ever known. I don't know anything about these vehicles. I have read it might be the coils and plugs but then people have told me it might be the torque converter.
I just bought a 2006 f150 exteneded cab w/ 5.4 V-8 and it vibrates when accelerating from a stopped position but not all the time---happens more when the wheel is turned. It definitely feels like the vib is coming from the left front side. I just got it back from the shop and the mechanic told me the vibration was stemming from the rear and that he exhchanged the fluid and added anti-friction additiver but that he expects the problem to continue.
View 4 RepliesI've had my 2006 XLT F150 (5.4L) for about a month now and have recently noticed what I can only describe as a 'smacking' sound under my truck when I accelerate quickly. It sounds as if I had something stuck to my drive shaft that is slapping the underside of my truck....except I don't. I don't think that its the timing chain because it seems to be coming from under the cab (between drivers/passenger seat maybe). I hear it most often if I try to quickly accelerate from a normal speed (50mph or so) to pass another vehicle. I do not hear it otherwise. Starts with a 'tink tink' then sounds like something hitting the underside. I'm perplexed at what this could be.
View 6 RepliesIt's a hot 110 degree day in my 08, we have 5 in the family. Parked for three hours and on return starts up normally. Noticed low torque and slow acceleration on take off. Got on the freeway and slowly got up to 65MPH with obviously only the ICE working.
View 1 RepliesThe other day we had a little rain, drove the car parked it left the wipers in the on position. Went to start the car again for another jaunt, and pressed the start button and brake pedal, the wipers came on very slow and the red triangle on the mfd came on. So I turned off the car and tried to start again, every thing was fine. So I am thinking my 5 yr aux battery is failing . Would I be correct in thinking that?
View 10 RepliesI have a 2006 f150 5.4l, and I have developed a problem. It seems the my truck has started to skip, or "pulsate" when I am accelerating. If I really get on the gas the "pulsate" goes away. This only seems to happen around 45-50 mph. Now this is where it gets weird. I have no check engine light on, and I have checked to make sure my light is working. I brought it to a garage and they told me something about Fords having a misfire issue that sometimes doesn't trigger a check engine light. . . . . now idk about that because every misfire I have seen triggers a check engine light, but I had them replace the spark plugs anyways. And it didn't fix my problem. At this point the only thing I can think of is possibly tranny.
View 11 RepliesI just bought a truck, it has a whining noise while accelerating, stops while letting on the gas, does not do it in neutral even if i rev up the engine. Only whines while there is some force on it, ie.. accelerating, or going up a hill at any angle, and does it from about 10-15mph- atleast 60mph.
View 2 Repliesi just picked up an 06 f150 with 5.4l 4x4 xlt package. Love the truck as it is my 1st Ford HOWEVER..... the truck is running super rough at idle and keep getting code for cylinder 5 misfire and bank 2 lean (which i am assuming is from cyl 5). here is what i have done so far...
New Coil packs
New spark plugs
New fuel module
New fuel injector on cyl 5
Still has a "stumble" when accelerating around 45 mph and shows code for cyl 5 misfire then will then throw code for bank 2 lean.
I have a 2016 Touareg Lux model with just 600 miles. On multiple occasions, when accelerating out of a slow rolling stop, the car bogs down and almost dies.....until I let off the pedal and gradually ease back on it. I was nearly rear ended recently as a result of the acceleration hesitation. It's almost as if the engine shuts down and is starved of fuel.
View 1 RepliesI've bought a second handed European Prius 2en Gen from year 2006, the car is wonderful and I simply love it ! I wouldn't change it for anything, but yet I have some problems with it.
When I start the car I get the Red Triangle on the front panel, and exclamation symbol, a VSC symbol and an engine (?) symbol on. On the Display I always have a black bar on the top with a car and an exclamation point on it. Both can be seen int the pictures below....
At this point the car runs normally, the only things I notice are :
1 - When I stop the car (without shutting him down) I notice that the consumption of fuel is at 99.9/L because it is charging the battery, which is already full.
2 - The back-right ventilation fan of the car (on the passenger seat) is ON even when the Air Conditioner is OFF.
After a few miles (I don't know exactly when it happens, sometimes it happens when stopped, sometimes when on the road), the car beeps and then it shows a, on the same black bar on the display, a message saying "Problem", after a few seconds I get a Battery symbol on the right of the car with an exclamation point symbol.
At this point the car starts having the following problems :
1 - The motor begins to speed like if I was at full speed on the highway.
2 - I simply can't do an uphill, the car won't pass the 20Km/h speed, if I gain balance before arriving at the uphill, it will start losing speed until reaching the 18-20Km/h.
At this point I really don't know how to solve this. I only know that, the Toyota Representative here where I live (in Portugal), ask me for 2,975Euros (almost 3,263USD) saying that it is a problem in the Hybrid System. But yet it seems strange because from what I know, if the Hybrid System was compromised, the car wouldn't start at all.
Does changing the 12V Battery on the back would solve this (even knowing that the Display shows a fully charged battery ?) ?
2006 Prius ...
Symptoms: The shudder feels like going over a "washboard" dirt road. It mimics the normal "cough / hesitation" that occasionally happens when the MG2 switches to the ICE while accelerating, or vice versa at a stop light. However, unlike the normal switching, this is continuous. It ONLY happens when accelerating; as soon as I lift my foot from the gas, the shudder quits. Although it is worse in stop-and-go, it is also noticeable on a clear freeway. It is worse with a cold engine, but continues from speeds of 10 mph all the way up to 80 mph (and probably higher.) The shudder is slower at lower speeds, and faster at higher speeds. It is most dramatic when making a left turn from a dead stop - the whole vehicle shakes. Weather conditions vary, but usually it happens on dry, paved roads, anywhere from 30-degrees to 75-degrees (F).
Frequency: first noticed a few months ago, gradually becoming more frequent. Now, it is almost every time the car is started. (Sometimes it accelerates without any problem at all.)
Diagnostics: The "Check Engine" light has been on for about 5 years (dealerships couldn't find anything wrong and it turned out to be the MG1 battery.) But when this new shuddering happens, the "Check Engine" light blinks continuously until the shuddering quits (i.e. let off the gas or brake.) There are no other indicator lights on (no triangle of death). And the diagnostics mode tells me nothing.
Other Info: The MG2 battery has not been replaced in the entire life of the vehicle. The MG1 battery was replaced, however, about 2 years ago. Regular oil changes have been kept up, along with air filter replacements, brake pad replacements, tire rotations, and all the other standard maintenance. It has had one owner, and is at 255,000 miles. MPG is currently at about 44.4 and has not changed since this problem started.
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.
View 2 RepliesMy Avalon tranny slips a bit sometimes when going slow around corners and then accelerating. Also, it seems to downshift itself when going down an incline at 45 or 50 mph. When entering traffic on a freeway ramp and getting into passing gear, it seems to slip quite a bit before catching and taking off. Is all this normal? 55,000 on the car so soon to go out of warranty. BTW, can the dealer check this out with diagnostic equipment as I would bet they couldn't recreate the problem test driving....never fails!

Driving on highway and accelerated to pass a vehicle, sudden slow down and all warning/error lights went on. Pulled to side of road and used Autel 539 to get codes P0A78 + P0A90. Scan code reader does NOT display the INF codes, so I can not get them.
Turned off vehicle and restarted. Put into drive and it appeared that I could move forward (and reverse) and was apparently running strictly on the ICE - no power coming from the DC motor for assist. HV battery would charge as driving down road.
It was slow moving, but as long as I was accelerating (very sluggish!) was able to move forward. If I took foot off gas pedal then ICE stopped running and would not restart when pressing on gas pedal.
So after doing some troubleshooting and researching in trying to find out on my 87K 2008 Prius Std "Noise in the engine while accelerating", "Approximately 10% reduction in fuel efficiency, due to lack of power from engine" & "Glide seems to be degrading over time", here is what I have observed.
1) When I push the gas when the car is parked the engine does not seem to rev in a stream, it goes up for about 3 seconds then goes down for 1 second, then again goes up and then down and this keeps happening until the gas pedal is kept press. In conventional cars the rev should be streaming continuously and proportionately to the pressure applied on gas pedal. This almost seems like a misfire, but from the drivers seat I do not hear any blasts, I have never tried this before so I don't know if Prius's are suppose to be like this. Also no Alarms on the MFD.
2) After using the 5.25 oz fuel injector cleaner in back to back half tanks I saw the engine regaining power and hence bettering the fuel efficiency. Does that mean I should get a Fuel Injector cleaning done by Toyota?
I have 2008 Prius with 80K and I will try my best to give all the information that I can. The past few days during about 10-15 MPH driving, my car started to shake a little bit when I try to accelerate. It doesn't want to go no more than 5-10 MPH and I feel like I was driving on the small bumps. It went away after 10 seconds. Again, I can't duplicate the issue. It happend only twice.
Could this be related to 12 V battery issue, tires issues, transmission, fuel injection, spark plugs?
