When I start the GX in the morning, the under hood has a sort of clicking noise almost like a roulette wheel after the car has been started and running. It then goes away after about a minute of driving.
You can't really hear it inside the vehicle, only if you're outside. The serpentine belt is relatively new and OEM.
Two weeks ago my car would not start, so I had a friend try and jump the battery. This battery wouldn't hold a charge, I took it into O'Reilly Auto Parts and they said the battery was shot. I put the new battery they recommended, the car ran fine for about 5 days. I took the battery back to O'Reilly and had them test the battery, it was too low to start the car, so they charged it and sent me on my way. The car ran fine for the rest of the day. The next morning the car would not start again, so I called the auto parts store and they recommended switching out my alternator. We switched out the alternator and the car fired right up, it ran perfectly (lights, heater, radio, etc) until yesterday.
While driving down the street, I noticed the radio head unit flicker, then it shut off. The car kept driving for about 2-3 city blocks, then all the lights shut off (dash lights, headlights, tail lights, brake lights). I turned onto a side street and the car couldn't go above 10-15 mph, it seemed. The speedometer and other gauges started going berserk, followed by a ton of dash lights coming on. The car basically rolled to a stop. I put it in park, turned the key to off and had it towed to my house. When I turn the key to accessory, all the lights work, as well as the heater and radio. But when I turn the key to start the car, a rapid-clicking sound comes from under the hood.
I've had my 2010 Prius for about 3.5 years now and this is the 3rd maybe 4th time happening. This morning I started the car and the car started to vibrate/rattle from the engine bay. It almost sounded like the wheel of fortune being spun but louder.
View 5 RepliesSo recently, my car started making whining noises upon turning the steering wheel during cold starts. Now, it does it when the car is warmed up too. From what I can hear, its only during slow speeds. Can't take my car to the dealership anymore cause they will charge me $140 diagnostic fee for whatever issues I'm having due to my car being "tampered" with previously. (It's all stock now).
View 4 RepliesCan't exactly pinpoint this yet but for sure it's very consistent. Every morning when the car is cold (and been sitting for 12 hours), when I get in the car and start, within the first 5-10 seconds, there will be a long buzzing noise coming from behind the radio or cup holder area. I don't feel anything is vibrating though. It goes on for like 2-3 seconds, then off, and usually another few seconds there will be another one or two short ones. after that everything is fine
when I leave work (warmer), I don't seem to hear anything at all.
My awesome 1990 Toyota Pickup (6 cyl., supercab), fondly named Ol' Rusty, has a measly 245,000 miles on it and still running strong. The one problem is that when it is very cold out such as this morning (-10F), I get a terrible noise coming from under the hood just in front of the steering column. It sounds like a belt rubbing, but I can't find it. It happens when I start going faster than 20 mph and goes away once the engine is completely warm. When it's happening, the speedometer jumps a bit. Interestingly, if I warm the truck up for 10 minutes or more so that the engine is completely warm, it still happens when I first drive the truck. Is this something I need to worry about or can I continue to ignore it like I have been for the last 3 years?

On cold weather conditions, doing a cold start, I allow the engine to run and warm up for a minimum of 5 minutes before driving. In this time frame the engine goes thru the whining sound and then the engine noise is quiet (normal).
What do other owners allow for engine warm up time before driving.
there's a noise that sounds like a seagull coming from under the hood near the steering wheel. Turns out it's the vacuum brake accumulator & there was a recall on this. Unfortunately I had the part replaced back in 02, so Montero won't fix it a second time. I only use the vehicle on the weekends & didn't see any reduction in the brake performance so I put the repair off. That was over a year ago. How important is it to fix this? Other than the really odd noise there doesn't seem to be an issue.... I'm just trying to decide the future of my truck since the transfer case is gone & I can't use 4wd or AWD and more. That's been broken & flashing about a year too.. On top of that the AC is broken & now there's a light tapping noise whenever the car is in gear, but not in park.. I really love my truck but am losing hope. Everyone says it's not worth fixing. 140,000 miles.
View 19 RepliesSo I finally went and put the exhaust I had been wanting on my truck. Pretty simple set-up. I had the factory muffler cut off and a flowmaster 40 series on it previously. I liked the sound under load and at cold start but normal driving I could not tell a difference from a factory muffler. So I had the flowmaster removed. I still have 4 cats so it's not crazy but it is loud. The only time I have cackle is on initial start-up not even at WOT which was a pleasant surprise. I just like the look of a single exhaust but still want some sound. I have been gone awhile as I needed a little break from starting and also being drawn in to arguments.
View 7 RepliesI'm experiencing vibration somewhere under the hood during start. I recently replaced the serp. belt and think it could be over-tensioned.
Possible?
Dangerous?
Or just the new belt needs to stretch?

I've got a strange squeal sound coming from under the hood only when truck is cold? It sounds like a bearing and after it gets heated up the sound stops. I talked with a guy thats a cummins guy and he said he had a similar issue and he had to replace the bearing in the turbo? Also when truck is warm it will still do it, like for instance, if I run in a store and truck idles for 5-10 mins it will do it only if I romp on it for a short while like 2-3 mins then again goes away. And if I'm idling or in neutral, hot/cold, it does not do it, it seems to be only under a load. Pull a 26 foot boat no problems.
I have been noticing a noise from the driver side back wheel. Like a buzzing sound. Is this normal? The reason why I am asking is I received the car like that and I do not know if something is wrong or is just normal operation. The noise can be heard while the car is parked so i do not thing it has anything to do with breaks or such.
View 12 RepliesI have owned my 2008 Rx 400 h for just over two months now and at the risk of sounding dense, am I right in assuming that when you are coasting along without the engine running, the heater will start to blow cold air? Everything works fine until you lift your foot off the pedal. This is my first Lexus/Toyota and hybrid so I'm not totally au fait with how it should be working.

On some 'cold' starts (and I use that term very loosely, because it never really drops below 40 degrees here), when the engine has sat overnight, and when I shift into reverse (never Drive, just Reverse) and stand on the brake I get a knock. I don't hear it in Park. Not valve clatter like on my german cars while the oil gets routed to the lifters, but instead a loud, startling deep-down knock that sounds like BAMBAMBAMBAMBAM. Then it goes away. Put it in neutral and the revs rise and it's gone. Put it in Drive and nothing there. Just lasts for maybe 5-10 seconds, but is it loud. BAMBAMBAMBAM! Like someone hitting a 2x4 on the block or tranny housing.
Once I'm past that 5-10 seconds it won't do it again all day. Just after a "cold soak". And perhaps 5-10% of the time.
There is a lot of examples with this motor of what some call "piston slap". Don't know if I have it - and I suppose it might get worse (to the point where I hear it) when the engine is cold and under load (in gear), but I don't get it in Drive. Just Reverse.
On cold start or when the cars been cool down for a hour or so, a huge cloud of smoke will come out. it smells plastic burn than a rich gas smell.
So far this is what i did, a oil change, add a no smoke oil treatment, replaced with an oem pcv valve (this fix my rx300 smoking issue years ago)
Video 1, Friday at 3pm. the temperature is ~60 degrees, less smoke after a pcv changed
Video 2, Friday after noon at 6p.m. ~50 degrees
Video 3, Next day 10 a.m. ~48 degrees
In person it looks white smoke, but the camera captures it more blue smoke. I have been constantly monitoring my levels and oil and coolants are just normal.
My Lexus Rx350 (2007) having problem starting the car when the engine is cold or switch off more than 1-2 hours. I need to crank the car at least 2-3 times to get the engine run. Once the engine run, i have no problem restarting the car with a single crack.
View 5 Repliesyesterday I heard a faint rattle coming from under the hood while the a/c was on, when I had my son turn it off, it went away. Right now it's barely noticeable, but I don't want it to turn into something major. I own a '08 ES with 88,000 miles and all my service is done at the dealership.
View 1 RepliesI recently purchased an 08 ls 460 and started noticing the infamous clicking sound coming from the ABS brake actuator under the hood. A $3000plus fix that is not in the budget nor will it ever be!..After doing some research trying to figure out what the actuator does i stumble across this Lexus technician PDF ...
..It clearly states on page 2 that "If a Toyota ABS system malfuctions, normal braking will not be affected!...My worry has never been the sound it makes,.. but that of me not being able to brake when needed!!...

MY Ls460 2010 AWD is making annoying ticking noise since I bought it 2 months ago ( 76k milage ) , it seems that the sound is mainly coming under the hood on right front fender side .
View 6 RepliesI started getting this weird sound after 10K miles service. I noticed it when i parked my car in the garage and the engine was off. I get this sound with or without turning the AC.
It sounds like a very fast tapping/clicking under the hood. (it is like a cooling sound but much faster) ..I don't think i got this kind of sound before. I don't know how to describe it.. Here is the youtube link: [URL] .....
It usually last for 30 mins-ish... Is it normal?
I have added a set of 10" subwoofers and tapped into the rear speakers to get the signal. Everything worked fine for about a month, then it started to make a loud subwoofer sound during start up, regardless of if the stereo was on or not. The amp manufacturer and the place who sold me everything said that maybe it's a noise cancelling issue with the cabin mics. Could this be true? If so, where are they located to disconnect them, are there any ways to disable them, or, would that sound still occur if I used the signal into the amp from either the fronts or the factory sub instead of the rear speakers?
