Prius (2004-09) :: Slow Acceleration / Battery Not Charging And Transaxle Slipping

I have a 2005 Prius with 110,000 mi. Sometimes when I accelerate the ICE (gas engine) simply spins (as if the clutch was slipping in a convention car) and there is little acceleration and the gas engine doesn't shut off when coasting or braking as it always has in the past. The battery screen shows it is not charging when this happens and is at 1 bar (purple). then sometimes the hybrid battery gauge will go from 1 bar to fully charged (green) in under a minute or 2 and then show discharging just as fast which isn't possible. It goes away after a restart sometimes but then happens again soon. Is it the TP sensor, Hybrid battery computer or ? I have gotten all kinds of codes including P0a93, P0a80, P1400, P040a.

Prius (2004-09) :: Slow Acceleration At A Dead Stop While Running Only On Battery

The prius stock battery is weak compared to my wifes Mercury Mariner battery. The Mariner acceleration on battery alone is excellent - she can get up to 30 mph in no time on just the battery. In my prius it has very slow acceleration at a dead stop while running only on battery. Is it possible to buy aftermarket (stronger) batteries for the prius so I can at least driver the car up to 30 mph only on battery?

Prius (2004-09) :: HV Battery Drop Discharge Level Running On ICE Only With Slow Acceleration

I have a 2005 with 165K on it. Just within the last 2 weeks, at start up, no matter what level the charge shows on the display, the HV battery will almost fully discharge and then come back up to full charge within a mile of driving. I just replaced the 12V battery thinking this could have been an issue, but it didn't change anything. The car never acted like this since I bought it in 05. When it drops to the discharge level, It running on ICE only, with the typical slower acceleration. What could be going on?

Ford F-150 (2004-2008) :: 2005 - Torque Converter Shudder Under Light Acceleration Going Up A Slight Grade

I am having a minor problem with my 05 F150 Lariat. Under light acceleration going up a slight grade the truck sometimes shudders (vibrates?). If I let off the gas or accelerate slightly it stops. At first I thought it was a feedback loop with the electronic throttle so I had the dealer reflash the computer but that didn't fix it. I've noticed that it happens right about the time the torque converter locks (looking at the tach) and I'm sure it has something to do with torque converter locking up and then disengaging continuously. Funny thing, it seems to happen frequently on the same hill at the same speed. What was done to fix it?

Elantra XD (2001-06) :: 2004 - Acceleration Is Slow

Girlfriend just bought a used Elantra. She told me about an issue shes been having with the car and how it feels as though its towing a trailer. I drove it for a day and noticed a few things. Vehicle has 110,000 miles

1. No CEL
2. Tranny seems to NOT be slipping (Revs climb just as slow as Speed)
3. Car feels VERY heavy at times. Especially on a start up-hill
4. No sputtering/misfires
5. Shifts up and down smooth

What I've tried so far:

1. Replaced Spark Plugs
2. Sea-Foam
3. Cleaned MAF/Checked Airfilter
4. Removed and Inspected BOTH Catalytic Converters and both seem to be intact. *plan on doing a back-pressure test as soon as I get the gauge from my buddy*
5. Checked timing marks

I put 1/4 can of seafoam in crank case and plan on letting it "run-in" for 25 miles or so. I plan on doing an oil change tonight as well as make sure the brakes are not hanging up (I should have checked this first, thinking back...but hind-sight is always 20/20 ) .

Prius (Gen 2) :: Slow Acceleration When Speeding Up To Get On The Highway

I'm a new 2007 Prius owner, and I know that the Prius is no sports car, but this acceleration is very slow. When I'm speeding up to get on the highway, it really sounds like the gasoline engine is working hard to get up to that speed. I've had cars in the past where the emergency brake gets stuck, can that be a probable cause, or is this type of slow, strenuous acceleration normal for the little Prius?

Toyota - Prius :: Slow Acceleration / Gas Mileage Down

My 2010 Prius since new, during cold Central IL weather, when I pull out onto the city street, it accelerates VERY SLOWLY no matter how I work the accelerator for 1-2 blocks. Then it takes off normally. When I forget to allow the extra time, it can be scary to have a car coming up fast and not be able to accelerate. I have left it at the dealership for 3 overnights now over 3 years. They went from "couldn't duplicate" to "there is a slight hesitation" that they attribute to normal shift from electric to gasoline. The next morning it took 2 blocks before it kicked in. My gas mileage has only been 35 this winter; I don't believe it has ever been consistently that low.

Prius (2010-12) :: Shuddering On Slow Acceleration

I have a 2010 Prius Pkg 5 with around 71xxx miles. I usually drive it like a regular car on eco mode and get around 38mpg average but recently I've changed my style of driving where I accelerate to the desired speed limit, let go of the gas, then reapply and keep the mpg meter in between the middle eco line and before the pwr band. I've been able to average 44mpg this way, which is great!

However, what I've begin to notice now is that say if I'm traveling at say around 45mph and let go of the gas and re-apply, the engine starts to shudder as if it's not getting enough gas. Why this is happening? I also need new tires (215/45/17) but that doesn't have anything to do with this. I've owned this car since 30xxx miles and haven't done anything other than put gas and change the oil at the dealerships. Could putting 87 octane gas with up to10% ethanol have any effect on this?

Prius (Gen 3) :: Angular Torque Method Is More Accurate Than Standard Torque Wrench

During my 35 years of experience as a production line and service engineer in the aerospace industry, it was my job to determine the least expensive and easiest foolproof way to perform any production and service operation.

Many readers here have related their experience with the oil filter housing and their difficulty with its removal and reinstallation with the need of a torque wrench to correctly tighten it. Most all technical tightening of screw systems have gone to the "angular torque method," as it is more accurate than the standard torque wrench.

Prius (Gen 3) :: Slow Acceleration - No Error Code Found

My prius 2010 (III) accelerate much slower than before. I started noticing this after I picking up my car from the airport. Parked the car there for a week. I have the dealer checked the computer but no error codes found. My car has almost 250k KM on it. I have not replaced the spark plugs the last three years. Could it be the spark plugs?

Santa FE SM (2001-06) :: 2004 - Slow Acceleration Which Is Worse After A Stop Sign Or Red Light

I have a Hyundai Santa fe 2004 6cyl 2.7 L , AWD. I am having problem of slow acceleration which is worse after a stop sign or red light. Sometimes while taking turns I feels like that I will not move and I was lucky to be not hit by a Car coming from opposite direction while taking a left turn today.

The Truck’s exhaust pipe broke recently and a auto garage welded it. But I am facing the above problem immediately after the repair of exhaust pipe. If I put more pressure on gas pedal then a mal function indicator comes and today I took it to another mechanic and he gets the error code of P0303 –engine misfire and wants to charge me ~ $600 $ to replace spark plugs and wires. The malfunction indicator goes off also while I am driving and can comes back after a while or a day. With the indicator on, the car drives erratic (minor jolts ) for few meters and then its fine. Since when I am driving on highways then I can go higher speeds without any problem. Is it still misfire issue???

Ford - Explorer :: 2004 - Acceleration Responding Slow / Tick Or Tap Coming From Behind The Dash

We have an 04' Ford Explorer NBX 4x4 (auto). We are not the original owners. It has a several issues.

1. Acceleration seems to be responding a little slow when I depress the accelerator pedal. Like a lag of some kind. Engine appears to idle and run fine. Just that subtle lag from gas pedal to engine response. No trouble codes

2. There is a tick or tap coming from behind the dash. This morning as soon as a put the key in the ignition the ticking started but went away after a few minutes on the road. But comes back when I come around turns (like a rounding off ramp from the HWY). Cannot figure out what it is. No trouble codes.

3. My transmission (4x4 Auto) when cold is fine, but when it warms up it seems to go into 4x4 mode and wont come out. All I have to do start going up a subtle hill (or incline) and it engages the 4x4 (at least that's what it feels like). I can hear the sound of gearing. When the transmission shifts it thumps really hard. At low speeds when I let off the gas it thumps really hard. We took it to the tranny shop and they said it was the rear end.

So we had that rebuilt. It was ok for a couple of months (rarely drive it). But it is doing it again, but seems to be getting worse. When in this mode it seems to feel like its dragging. We recently serviced the transmission filter. Replaced fluid. We reset the computer to relearn daily driving. But didn't work.

I was thinking of replacing the 4x4 module and or solenoids in tranny, or 4x4 motor on transfer case, but I don't want to spend money if it doesn't fix the problem. No trouble codes. Are all these issues related to one another? Is one issue causing the other problem to exist?

Prius (2004-09) :: 2006 Won't Go Above 35 Mph While Being Very Slow Accelerating

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.

Prius (2004-09) :: Wipers Going Slow And Red Triangle Came Up

The 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?

Prius (2004-09) :: Red Triangle / Slow When Driving On Uphill

I'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 ?) ?

Prius (2004-09) :: All Warning / Error Lights Went On When Suddenly Slow Down

2005 Gen2 with 216k miles

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.

Passat (B7) :: 2012 - Acceleration A Bit Slow On Takeoff

I recently picked up a 2012 Passat. I love it. Comfortable ride compared to my Volvo, looks amazing from the outside and, well, its a VW - always loved them.

So, my only question is about the acceleration. It tends to be a bit slow on takeoff. Its hard to explain, really, but it creeps a bit and then I find that I need to push relatively hard to get the RPMs up to get the car to accelerate. Ive never had this type of issue in a car before so I thought I would ask to see if this is normal. At first I thought it was maybe a gas saving feature. When I use Sport Mode or Sports Shift it accelerates fine with no issue.

Passat (B5) :: 2002 - Acceleration Is Very Slow At Times

I recently bought a 2002 VW Passat 2 weeks ago. I love the car and the drive, but the acceleration is excellent at times, and very slow at times. Also the car gives me a stutter step every once in a while while at low speeds....I bought the car in Mass so I have 13 days left for the dealer warranty. What it is?
