Prius (2004-09) :: 2007 - Brake Seemed To Engage Then Disengage Causing Engine To Stutter And Surge
Aug 2, 2010
Is there a correlation between a Prius sitting in the hot sun and the computer malfunctioning? When I came out from a movie yesterday, the temps read 106 degrees outside the car. The emergency brake light was on, though the brake was off. I pumped the brake on/off a couple of times, but the light stayed on. As I pulled out, the brake seemed to engage, then disengage causing the engine to stutter and surge. The service tech today tells me the computer is not communicating and at 50,000 miles. Is it worth the money to get the new computer? Will the car be safe afterwards?

owner of a 2007 Passat 2.0T wagon, 6 spd manual, 32k km's. (leased) I'm having repeated persistent parking brake failures (won't engage, or won't disengage).
-About two months ago the parking brake would not disengage, error message on the MFD, yellow warning light and warning tone. Called roadside, finally got it disengaged by removing one terminal from the battery. Took it straight to the dealership, they "fixed" it by resetting the computer.
- The next day I have auto hold engaged, parking brake did not disengage when I turned the car back on. Had to turn engine on/off several times before it disengaged.
- Took it to the dealership again, had to get a rental car over a weekend while they diagnosed the problem. This time they changed some wiring and replaced the parking brake button.
- Next day the parking brake engaged ok but wouldn't disengage. Same routine on/off/on/off to get it to disengage.
- Back to the dealership again, they decided to replace the brake control module but didnt have stock.
- Last week I took the car back in (4th trip for this issue), they replaced the module and said it was fixed. Next day my wife got stuck in a parking lot with the parking brake stuck on.
- Called the dealership last friday and asked them to come pick it up this time, as my wife and I are sick of the inconvenience of this issue. (we share the car, both work, and also have a child's daycare to schedule around)
The problem is intermittent but not difficult to cause a fault. Can be caused when engaging, disengaging, or when the PB kicks in from auto hold when turning the car off. I try not to use it, but sometimes is necessary (parking on hills etc).
The dealership doesnt seem to know the problem and are just throwing parts at it. What recourse do I have for repeated problems? The manual recommends using this parking brake EVERY time the car is parked, so I don't think it's too much to ask to have it working properly.

I've recently started to have issues where when I get up over 55/60 mph the traction control will engage and limit the acceleration of my 2009 prius. I took the car into my local Toyota dealership and they claim it is because of the size tire I have.
I recently purchased a set of Hankook Optimo H727 replacement tires. After having done my research (mostly on these forums) I decided to go with the P195/60R15 tire size. Now I have several reasons to believe that the dealership has misdiagnosed the issue:
1. There are loads of people on this site who have installed 195 size tires (and larger) without issue as far as I can tell.
2. The issue did not begin immediately after installing the new tires, but rather a couple months later.
3. My brother installed the same exact tires on his 2005 Prius and does a lot more freeway driving than I do and has not had an issue.
4. My understanding from reading here is that in some other countries Priuses come with 195 size tires stock.

I have a 2006 Jetta with a 5 speed manual transmission and 35,000 miles. The engine randomly misfires causing it to stutter or stammer. The check engine light is on and has been for several weeks. Occasionally the check engine light flashes. I took it to a local mechanic who ran a series of diagnostic tests (no vacuum leaks) and they recommended having all the ignition coils replaced for all 4 cylinders. They also replaced the fuel filter. I did so but the problem soon returned to which they referred me to the dealer.
I decided to take it to a VW specialist in town and they replaced the spark plugs for all 4 cylinders. They noticed that some of the plugs were black with a buildup and some were clean. The problem soon returned. The VW specialist also recommended that I take it to the dealership as they too had no clear idea as to what the problem is.
The car did suffer rodent damage in 2007 but was still under warranty so all the wiring that had been chewed on was replaced. I experimented using premium gas and regular gas. Premium gas seems to make the problem worse. Also, the misfires seem to lessen as the weather gets warmer. I would like to fix the problem to avoid any catastrophic failure but am trying to avoid throwing money away on any more guess work.

2nd gear runs fine, but occasionally, when in first i have a real bad stutter in the engine and it continues from the moment the clutch begins to engage on up. The car just seems to jump or skip along rather than run smooth.. It occasionally will work itself out but other times will continue for 5 seconds at which i switch into second gear and everything is gravy from there. What the main root cause of this is? I don't want to get the wrong thing fixed which I've been trending on lately.

When engaging the engine braking ( B ) function on the Prius IV, do the brake lights come on to warn the driver behind me that I'm slowing down?

Replaced my coil packs/sparks, and just got around to changing my N75 valve today. The rough idle issue is gone but now when I go WOT it boosts but goes from 15psi-12-13-12-14-12...etc. I've checked and there are no boost leaks. I do have a CEL saying I need a new bank 1 sensor 1 Oxygen sensor. If it is that, why did this problem arise as soon as I changed the N75 valve and wasn't present earlier?

I have a 2007 Toyota Prius. When I press the brake pedal and press the start button the engine does not start or the wheels are not powered by the battery. It gives me the following errors:
The indicator in the Start button lights in Amber Color.
0 kmph mark is not activated in the dash board pannel.
When I shift the gears it only shifts to neutral ("N") gear.
I cant move the car forward or backward. An error message is displayed in the MFD in Japanese language. It is in Japanese and I cant read the error message.

I have an 02' 2.0 Jetta Wagon, and the A/C is having some issues. Since I know close to nothing about A/C systems, I took it in to a few places to have it looked at. I've had the whole system Evac'd and recharged, and have had the low pressure fitting replaced (apparently there was a slight leak there), and the system is still not working.
The A/C worked fine when I first purchased the car a few months ago. Shortly after my 800 mile trek from Oregon, back to home, the A/C started to only work intermittently. The compressor would engage, then disengage, repeat...It seemed like a bad idea to keep trying to use it in its sad state so I stopped using it altogether. As I said, I had the system emptied and recharged, but it still only works intermittently. It sort of follows a pattern where upon start up it works longer, and switches on and off at shorter intervals, until it doesn't engage at all.
There are no strange noises from the compressor, and when it was hooked up to the machine, it proved to be performing its function well.

I recently bought a 1997 f150 4x4 with shift on the fly. I bought the truck from an old man who parked it outside his house. I love the truck, but the 4x4 has been finiky. I have done a ton of research and i have done a bunch of testing. The vacuum system is working correctly. I have tested the solenoids and the front axle actuator is working properly.
There is some kind of electrical issue. It might be the GEM (i really hope not), but it might be the shift on fly switch itself.
The 4x4 will engage, but when i turn the switch to 2h nothing seems to happen. Driving in reverse doesn't work. But sometimes it switch from 4h to 2h, just by turning the truck off and restarting it. If restarting doesn't work, then i have to pull the 5 fuse, let it sit, then put it back in. I read that this resets the GEM. (Number 5 fuse, middle row, 5th from the top).
Resetting the GEM usually does it, but not all the time. Sometimes it will still be in 4x4 again after resetting the gem. And then what is really weird, after driving it in 2h (after the gem reset) then turned it off and restarting it, it will go back into 4x4. All this happens with the switch set to 2h. So I have been having to reset the GEM, each time i restart it. (This was going on for a day or so.)
Any easy testing i can do? Do you think it could be the switch on the dash, or more likely to be the gem? I hope it isn't the gem. I don't want to have to pull a fuse each time to drive my truck.

The A/C in my truck stopped working last year, and this year I intend to fix it. I believe the problem is with the compressor clutch because it was making noise as it would engage or disengage. It was making this noise for a good year or so, and then one day the noise stopped and I have no A/C. So I am only assuming its the clutch.

I think this is just poor dealer service, but I need a sanity check.
I have 93k miles on my Corolla. My clutch creaks like an old school bus when I engage and disengage. It's done this pretty much all along and I think I had another dealer successfully lube the linkage to quiet it down -- it was miles and years ago so I may be misremembering that.
My current dealer says all they can do for it now is REPLACE THE WHOLE FREAKING CLUTCH assembly to the tune of $1,300. Clearly, I'm not doing this. As long as it works, I ain't replacin' the clutch, but, REALLY?

I went driving today and for a moment I could engage/disengage the clutch pedal with little to no effort. It goes back to the normal force after 3-4 shifts.
It's the exact opposite of what's happening in this thread. [URL] ....

This past monday morning I got in my 05 Legacy GT w/ 82,000 miles. When I turned the key it acted as if the starter engaged for a second then disengaged and made the typical motor winding sound. I tried it several more times with the same result. So I reluctantly called my local repair shop and had it hauled over for what I thought was possibly a bad starter. The mechanic went out to check it to see what it was doing and when he did, it started right up…..!! He said that when it started it ran as if it had been flooded for a minute or two then cleared up. Throughout the day he drove it around and started it about 20 times and said it “appears” to be ok. It’s a small shop that I trust with my other cars but they don’t have the tech to pull codes on a subaru. So my question is, what was the cause of this issue? Neutral Switch? Cam Sensor? or a Fluke?

So I just had my entire clutch replaced while another repair was taking place. What I've noticed is the "clutch engagement" has changed. Where as I would have the clutch start to engage/disengage at the 1/2 way point on the pedal travel is now the last 1/4 of the pedal. Is this a "normal reaction to a new clutch that just takes getting used to or is there an adjustment I can fine turn it with? Do I just have to wait for it to "break in"? When I replaced the clutch on my dearly departed 94 ranger, I replaced the bearings & disc only reusing the pressure plate and did not have this issue.

I just bought a 2007 f150 4x4 5.4 triton with 69 thousand miles less than a month ago. Since then the transmission has been rebuild but come to find out a misfire will cause overdrive to act up, and it just recently started misfiring badly. It was throwing a code. 2 coils were replaced and still misfiring. It's not throwing a code anymore. No check engine light flashing or nothing.

I have just recently bought a 2006 prius (T Spirit model in the UK) with 46k miles on the clock.
Anyway i took it into a local garage today for its full service, as part of the process they disassembled the brakes to inspect them. unfortunately when they put it all back together, all the brake related lights have come on (VSC, ABS, anti skid, handbrake) and despite the mechanics efforts to reset them, could not turn them off. When the car is turned off the brake pedal now feels loose and makes a funny twang noise as if it has come off its spring. there are also dull noises coming from the brakes when i am driving the car and turn the steering wheel full lock to the right or left.
What has really annoyed and scared me is that when i now drive the car and brake, on releasing the brake pedal i get the feeling the brakes do not disengage immediately, instead there is some lag with the brakes disengaging a second after i have removed my foot from the brake pedal and makes the car jerk a little before coming to a stop. the car also feels sluggish to drive and on the drive back home only managed to achieve 45 mpg (heart breaking!). the mechanic has promised to take a look at the car next tuesday (we have a long public holiday this weekend so most stores will be closed) leaving me to suffer 4 days of anxiety and non use of my car.

I've noticed that when accelerating from a stop and turning onto an adjacent street to the left or right, there seems to be stuttering or shaking coming from the engine. I'm usually in ECO and only 1/3 of the way into the "engine half" zone on the HSI. It's not consistent but has become a bit of an annoyance.

98k miles and if the car is on a slight incline and your backing up or creeping forward it feels like you are going over a rumble strip. that slight stuttering feeling. no codes have tripped. I've asked the toyota dealership and they don't know what could be the problem. The trans axle fluid was changed at 88k and from what i was told there were no metal shavings in the fluid. it was a little dark but after going 88k miles i assume it would be.

I bought a 2008 5.4l xlt about a year ago now. For the first time I took it on a trail that had a little mud. With my incredible wisdom, I decided to park the truck rather than wash it off. The next day the engine started making weird noises when I turned the steering wheel. After washing the truck it still made noises so I opened the hood. THE ENTIRE engine compartment is covered in a serious amount of mud. I feel that this has to be what started the noises when I turn. Mud dried in the wrong place? The noise sounds like a whine and its pitch matches the engine rpm until over 2500 where I don't really hear it anymore. Is there a way to flush the engine compartment?
