Prius (2001-03) :: Loud Sound When Engine Is Running - Shuts Off If Brakes Lights Came On
Oct 23, 2015
My 2001 Prius makes this sound when the engine is running. All the battery lights are on all the time, I think it needs a new HV battery but I'm not sure if it's worth it. Perhaps the other battery is faulty I really don't know. All the engine lights are on and if the brake light comes on it starts shaking or the power steering fails or it just completely shuts off on the road no lights no power steering nothing. When that happens I use a battery booster that I keep in my trunk to get it going again but it's really dangerous to drive now.

I have about 200k on my forester. Friday when I was leaving work I cranked it up and it made a loud knocking sort of sound. I drove it home (about 15 miles) and on the way the sound lessened. It was louder when the car was idling but she made it home ok. Next day, started the car and it happened again. Not more than 50 feet up the road we stopped at a stop sign and it sounded like a semi was starting up around the corner. Much to my dismay it was not a semi but my own car. Engine shut off. We pushed it back to the house and tried to check it out the next day. This time, we started it, didn't go anywhere, and within 30 seconds it turned off. Same loud knocking sort of sound. The confusing part is that all of this happened within two days. There was no gentle sound leading up to it for a few weeks or even a few days. Knocked on Friday, shut off on Saturday. What could be going on?

Recently my brother in laws truck started making a buzzing sound while running and a much louder sound after it shuts off. Trying to track down the sound. Listen to the whole video because the end is where it gets loud.

I'm the loudest Prius in CT right now. My brakes doing that loud scraping sound. Is it normal to need brakes this soon?

I have some check engine lights. And there is one light on my monitor screen in the top left. That one is a hybrid system warning light I think. I'm sure I need to connect it to something to read the codes.
It is running fine, but the engine doesn't seem to shut off and mpg in city is kind a like a normal car, and I think the battery drains too fast. No matter how slow I take off it won't use the electric motor alone. I wonder if that is the battery causing engine to have to stay on.
It keeps cycling off and on charging the battery, but engine never shuts off.

So I've got spongy brakes on my 2003 Prius. I've flushed the whole system twice. Replaced the hoses, pads, rotors, shoes, and drums. Still spongy. I'm not sure what to check next. No lights or codes. I'm leaning toward the master cylinder. You can pump the brakes up when they become spongy and they hold solid. If you practically stand on the brake pedal it will slowly bleed down. This tells me the fluid pressure must be escaping somewhere. I don't want to just blindly replace parts.

My 2004 Santy 3.5L (I am the original owner) just turned 91.4K miles and all of a sudden a VERY LOUD Engine Knocking sound came from the top of the engine. I have been changing my own oil since new with synthetic Mobil 1 and a new filter every time, and I never had any issues. I changed it last week at 90K prior a Spring Break trip (1350 miles).
Then yesterday after I let her rest for 1 day, I took the kids to school and within 10 miles of my house the ticking HARD loud noise started happening. I pulled over near a shop (within 1 block of where the noise started) and they said...don't drive it it sounds like a lifter collapsed, or a rod bearing or something big...
I had her towed to the dealer and the first thing they told me is to gather all the oil change receipts and a "manifesto" and they asked me how often I change the oil... I said every 5K miles. I change my own oil and have done since day 1.
BTW, Timing Belt, Water Pump, tensioners, belts, coolant, spark plugs and coils were changed last year at 77K miles.
The car should still be covered under the 10year/100K Powertrain and I believe they are trying to build a case so Hyundai can cover this or not...
They still need to tell me what's wrong... I change my own oil so I don't have receipts for "oil changes" and I have a log of when oil was changed...

I have a '99 Frontier (3.3L V6) just had the radiator, hoses, fan clutch and 3 exterior belts replaced. Car's not overheating anymore, BUT, now I hear intermittently a "clack" (which sounds similar to a loud compressor when it shuts on and off). Car never made this sound before the repairs mentioned above were made.
I took pictures and could use finding out what the part is called that is making the noise. I see the 3 discs on the front side of one of the belt pulleys (i think?) spinning, then they will stop, making the clack sound. It seems to me that sometimes the sound is loud and then other times it is extra loud --are there two sets of these discs and the other set is somewhere I can't see?

Last year I purchased a 2001 Ford Ranger XLT 4x2 V6 3.0L 48,000 miles, in perfect shape. I haven't had any problems until the last 6 months I have noticed the check engine light was on. Ok, while at Valvoline, the checked it and said it was a EGR code and that it might have been just an O2 sensor problem, something minor. So they just shut it off. Well it popped back on and I just figured I'd leave it alone. Maybe a mistake.
6 months later. So driving today the dang thing just quit and shut off? No warning, just everything shut off. It happened 3 more times...Then tonight, driving down the highway it shut off again, no warning? Happened 3 more times, couldn't make it home, called and had it towed to my apartment. $30 bucks later, at least my truck is at home.
So the problem is it won't stay running, and it just shuts off all of a sudden? It starts fine, drives fine, but unbeknownst to me it will just shut off, 1 minute later, 5 minutes later, it doesn't keep a pattern...It could be a million things I guess, but I'm not really able to pin point any exact locations. It's not making any funny noises, nothing fishy, but won't stay running. It's doesn't seem to be hurting for gas, it has 1/2 tank, no gurgling noise...
It's Saturday night and my Girlfriend's and I only transportation....So we have no vehicle until we can get this fixed, given that sunday no one will be open...we're playing it by ear.

I own a 2001 Jetta 1.8t with Gti front end. So I was driving downtown the other day and I bottomed out really hard and cracked my oil pan. I didn't realize it was cracked and leaking so I drove it home, drove fine with no issues at all. When I got home I parked it and went inside and in the morning I came out and tuned it on for maybe ten seconds. It made a really loud ticking sound that was constant and oil pressure was almost all the way down. So I shut it off and looked and saw the oil pan. I fixed the oil pan yesterday and started it up and it sounded really good and drives fine. But I've been hearing a pretty decently loud ticking sound when everything's up to temp and warmed up. The ticking is only at an idle and it drives like it use to just sounds bad at an idle. Some people think it's my oil pump and tensioner, some people thing I ruined the turbo and possibly internals.

I own a 2012 Black Golf TDI, had it for about 3 months now and loving it.
Anyways, so I'm aware that when the car shuts off, the fan is still running until it finally cuts off. Last night I got home and when I exited the car, it was blowing pretty loud like the car was still on. I didn't think much of it and just went in the house for a few minutes. It was bugging me that it was louder than usual so I went out to pop the hood to see what's going on. Found nothing so I went ahead and started it up again and shut it off. The fan noise went away after that and shut off properly.
Is there any harm that the fan was blowing louder than usual? I know it's a little vague but just wanted to get an idea because this was the first time it happened.

I applied brakes while car was moving slowly, less than 10 mph, and heard loud grinding sound coming from left front as car stopped. Shifted to reverse and car barely moved, less than 1 foot, which was accompanied by the loud grinding sound, then stopped. I could find nothing interfering with the wheels but did find pieces of brake pad on the ground along the path the left front wheel had followed. The left front wheel appeared as if the calipers were holding whatever remained of the brake pad and/or backing tight against the rotor. brake pad fell apart on 2002 at 43,561 miles...

I recently had my oil changed at Toyota dealership at 11,700 miles. Picked it up after 2 days and upon starting heard a very loud rattling sound from engine; as if it were going to drop right out of the car. Shut it off and re-started ok, but very concerned. No repeat of incident until this morning. Same sound at start-up (now at 12,600 miles). My daughter who was inside the house could hear the noise. I used the car the previous day, parked outside in driveway as usual. Now very very concerned.

I have had a problem with my 2009 Chevy Aveo since I purchased it last October 2010. Every once in a while the engine shuts off, not while I'm stopped, but usually after it's been running for 2-3 minutes. It doesn't happen more when it's cold or hot, and not necessarily in the morning or after it's been off for a long time.
It happens only once every few months, but when it does happen it's downright dangerous. Today I was pulling into traffic turning right at a red light and it shut down. I was up to about 15 miles an hour still in the turn, and it feels just like the power steering stopped working. Because it's happened before I knew what to do. If I throw it in to park and turn the key, the engine starts fine and it has never happened twice. In 15 months of owning the car it's probably happened 8 times.
I've brought it into the dealership 4-5 times and they've never been able to replicate the issue. They replaced the spark plugs etc. but it always happened again a few months later. When I went in recently they told me it was the battery and it wasn't covered under my warranty.
They also say because I didn't mention it last time I went in, it must be a new problem. I just didn't mention it because it happens rarely, and they can't find what's wrong, I don't want to seem like a problem customer.
My clock is resetting now and it's a different time every time I start the car so the battery may be an issue... but the engine has never had any trouble starting, not even a hesitation, and the radio stations haven't ever reset.
Can the battery cause a running car to shut off completely, and if so does that mean it had a bad battery when I bought it there used? I can't afford a new battery right now (well as long as it is still starting fine) and frankly I don't believe that's the problem.
Is this a computer issue in the car?

Today check lights came on for active suspension, brakes and engine. I lost regen braking but normal brakes worked fine. I switched the engine on and off and the lights cleared and regen brakes worked again. When I checked the codes with Scangauge it said 27 pending codes but only gave me P0001 (Fuel Volume) , B2600, and B2501.

My girlfriend has a 2010 prius with the navigation package. We go to the drive in movies quite frequently because it's cheaper and close to us. Every 30-45 minutes the prius will automatically shut off the battery. The interior lights turn on and the sound goes off.
We are kind of getting tired of getting dirty looks when this happens. So we're wondering if there is a way to take this setting off.

I have this light tapping sound that I don't believe is native to the otherwise healthy Prius II I'm currently driving. Mine is a 2007 Prius II with about 106,000 miles. The sound occurs persistently when the vehicle is ON but the engine is not running and the ventilation system is off. If I press down on the brake pedal I hear a light tapping similar to tappets in older cars.
But since the engine is not running at this point I don't think the problem is there. If I let up almost all the way on the brake the noise goes away. I bought this car with 103,000 so I know there may be things that I need to tend to. I'm not experiencing any braking problems. I'd rather have some idea of what's making this sound before I check with a mechanic and incur a few hundred dollars of expense.

My 2008 Prius has started making a noticeable soft whirring sound whenever the engine is running. You can hear it both inside and outside of the car. The sound lasts exactly 30 seconds, then pauses for 4 seconds, than repeats . When the car is turned off, the sound can be heard for about another 10 minutes before it shuts off entirely.

I decided to go for a stroll and about 10 minutes after heading out, sudden the Brake and ABS lights come on along with a screeching alarm sound from the cabin. I pulled over right away to check for leaks and my brake fluid. There were no leaks and brake fluid was full. I decided to head back home and when I turned the car back on, I lost most of my brake pedal and it became completely spongy and would sink down when depressed. I had to drive home with my emergency lights at about 15 miles per hr in hopes of being able to stop in time. I double checked when I came home, no leaks whatsoever.

My check engine light came on today and my fan has been running pretty loud for the last couple of days. Also when I start hitting the gas under 1500 rpm there is a little rattle that I can here but it goes away around 1500 rpms and you can also hear it if you let of the gas and let the rpms go down then hit the gas again pretty hard?? It is a 2000 lincoln ls with the v8 around 110k, and i have had numerous problems with it. About 6 months ago i replace about 5,000$ worth of parts including, head gaskets, coolant clutch pump, power steering pump, timing chains or belts, and other things because I was having overheating problems.
