Camry :: Toyota 2007 Banging / Grunting Sound When Starting Engine
Mar 1, 2015
I've a 2007 Toyota Camry (LE 2.4 L 4-cylinder). Couple of days ago I tried to start the car and I heard this banging/grunting sound as I started the car. And, after the car started the engine is running much louder. Oddly enough when I got out of the car and opened the hood the noise didn't seem that loud. In other words, it sounds louder from inside the car than standing outside with the hood open.
Before all this, the engine ran very smoothly and very quite. Here is a link for two audio files that captures the sounds. Note that I recorded these two clips from inside the car.
First when is when I'm starting the engine (the sound can be heard at around 6-7 seconds): [URL] ....
Second is when the engine is running loud (I'm not driving the car...just sitting there letting the engine run): [URL] ....

A 2007 Toyota Camry 2.4 was brought into the shop I work at smoking badly and running terrible. The car had been run hot because the radiator was busted and it blew the head gasket. So I pulled the head and sent if off to the machine shop to have it checked. They said it was badly warped across three cylinder and they resurfaced it.
Now I have everything re assembled, but it simply will not start. All the timing marks on the timing chain line up where they should be. All four coils are firing. Injectors wires pulse noid lights. A few times it has hit and sputtered like it was trying to start but never successfully does.

I have a 2000 Toyota Camry LE with 106K miles. It?s getting a little clunky but works perfectly. I do regular maintenance like oil changes every 3 or 4 months, breaks, tires. Last year one day during very have down pour rain I noticed something banging/hitting under the seats while driving in this heavy rain & car losing power (slowing down). Something (I am guessing the exhaust pipe? hitting the body. The more gas I gave to gain speed the violent the banging. I slowed down to almost 15MPH but never stop & the car started to work normal. It happened 3 or 4 times before I got home. I check all fluids etc? All normal. Drove later in sunny, cloudy & even in light rain the car runs perfectly fine. Then it happened again in heavy rain.
I told my car mechanic & he checked all even tightened the main belts (not timing belt). No change. Now it?s so predictable when ever its rains heavy & even slushy snow/rain. Lately it started to not only lose power but sometime instead of banging I hear grinding noise when pressing the gas paddle. Some time banging followed by grinding but every time after slowing down the car recoups power and I drive normally. It never ever happens in dry day. My wife who drives ?Buick Century 2004? thinks my car is dyeing and should buy a new. When I describe this situation to any mechanic they points to transmission & want to perform brain surgery to diagnose.

I have 2007 Camry that makes a humming noise when A/C and audio are on at the same time. Pitch increases as I press on the gas pedal and decrease to a steady level as I depress on the gas pedal. What could be a cause of this phenomenon?

I was driving today and as I descended a steep hill the car made a horrible banging sound and the check engine light came on. I got home and the light has since gone out. What happened and is this bad?

2000 GMC Sierra 2500 6.0L gas engine 150K miles. After returning home from a 150 mile drive, I notice a very heavy sound of marbles banging around near the front of the engine at idle. The noise is a much like heavy detonation where timing is badly off kilter. Used my stethoscope to determine this is loudest at the water pump housing. The belt runs smoothly with no sign of unusual resistance. The engine does not overheat, and there is no sign of a coolant leak.Can a bad water pump shaft bearing make such a tremendous "cackling" noise? What else could it be?

I have a 1999 Toyota Camry 2.2 4cyl with 220K+ miles.
I was driving on the freeway when I heard a loud "POP" and rat-tat-tat cracking sound from my engine. I managed to pull over on the road where the car rolled to a stop. I tried to start up the car and the starter cranked, but the engine wouldn't start.
I thought it might be a broken timing belt since a similar situation happened to a family member (who was driving another Camry) a couple of years ago, and we were able to fix the car by changing the worn down timing belt. So today I spent all day taking things apart and finally got to the timing belt, but to my surprise, the belt looks completely fine.
I fear I might've actually blown the engine but don't know how to diagnose this.

We have a 2007 toyota camry 2.4l which had a engine problem so car needed a rebuilt engine. so we went to auto repair shop and they installed a rebuilt engine.But when we went to pickup the car the owner of the shop said our a/c is not working and he doesn't know why. he said its a/c compressor clutch is not working. the a/c was working fine before the engine installation. when I talk to other people (different mechanics) they all say that the repair shop who installed the engine caused the a/c problem. How can I prove that so I maybe can sue the guy in a small claims court? for a good gesture the owner of the shop offered us free labor on installation of a/c compressor but not on part which I can bring my own. I need detail argument. people say that in order to win in a small claims court we need many supporting explanation from experts. we just want the a/c to work again. car drives fine after new rebuilt engine.

Yesterday I started my 2011 Prius, about 3 seconds later (Im guessing here) I pushed the A/C button, the engine started (at the same time), and I got this horrible grinding, clunking, bucking noise from under the hood. It lasted for about 5 seconds then stopped and everything was fine. Engine ran smooth, A/C was running. I turned off the A/C thinking that might be it and started it again, again everything ran smoothly. I pushed the start button the shut down the car, waited about 15 seconds, pushed it again, all normal, again with the A/C on. I put into drive and moved forward, allowed the engine to start, no problems. Smooth operation, everything normal.
I gather it'd be a good idea to take it in, but want to know how many "on-off cycles" until a problem is erased from memory. I did drive it last night (everything ran just fine) and went through 3 "cycles". What this could be? Bad fuel?? I have a 2011, with about 38k miles on it. This is the second Prius I've owned and have never had a problem before, let alone something like this.

Today my check engine light came on and the code is P0712. When I drove off from the parts store, the check engine light suddenly went off. What should I do at this point? What are the most likely problems/solutions.

I recently bought a 2007 toyota Camry le v6 with less than 38,000 miles it currently has 39,300 miles and my check engine light is on along with the VSC and a skid control light (car with squiggle lines behind it) we have a had lots of rain here where I live and I had to drive through a couple deep water puddles. I looked up online and it said The engine light may turn on if the VSC and skid control lights are on. Could this be that the sensors maybe got wet? I don't think anything should be wrong with this car considering it's a toyota with less than 40k miles

I am the original owner of a 2007 Camry SE V6 with 95K miles.The car has been meticulously maintained. About 2 weeks ago I started to notice a mysterious sound coming from the passenger side of the engine ONLY when the engine is idling. It has a higher, light pitch but when revving the engine slightly it goes away. Obviously when driving it can not be heard with all the other road noise etc. Also it makes this sound at different times, sometimes days with no noise, very irregularly. I checked that section of the engine bay and see no moisture, leakage or discoloration anywhere. Also serpentine belt shows no wear or wobble. Could it come from the water pump? I am very concerned that something will soon snap off, break and leave me stranded.

I am having camry 2007 with 100 k.miles running. When engine crosses 2000 rpm, I can hear a tik tik sound from engine. This sound is not coming when engine is cold, and also when the engine is on acceleration.
I have checked alternator and A/C bearing. It's OK. I have also replaced timing chain tensioner.

When the engine of my 2007 Camry LE V6 is cold, it makes a ticking/knocking sound. The engine has 100,000 kms on it (60k miles). The frequency of the sound varies with the speed of the engine, not with the speed of the car.
When engine is cold: The sound happens roughly twice a second when the engine idles (at 700-800 rpm).
When engine is warm: The noise is less audible. It can be heard when idled at a stop, but you have to listen for it. The noise cannot be heard on the highway.
The car doesn't burn oil, and the oil level is ok. I had the oil changed 3000 kms ago, and it is still very clean (clear). The was the same before and after the oil change.
I am wondering if it could be the lifters, bad plug, or maybe a timing issue.

I get a call from my mother saying their 1994 Toyota Camry 2.2L car won't start. I went over there today and the first thing I check was the spark. I hooked my spark tester and had my dad crank the engine over. No spark. So I removed the distributor cap and tested the resistance on the primary and secondary sides of the coil. The secondary side was low. So I went and got a new coil, installed it and it still wouldn't start. I checked the spark again and it had spark, but still wouldn't start. I then proceeded to check the fuel pressure. I hooked up my pressure tester to fuel filter, with the included adapter, and had my dad turn the ignition switch to ON position. No pressure. Then I had him try and start the engine, the pressure jumped up to 41 PSI. I then sprayed a little gas into the throttle and the engine would try to start. I'm stuck.

A month or two ago I noticed my car starting to turn over a bit slower. Then finally woke to car that would not start. I tapped on the starter and it turned over. I took the car to local AutoZone store, tested the electrical system while the car was running...Starter - Good, Alternator - Good, Battery had a few dead cells. I also took out the alternator and starter to have them bench tested. Both passed. So I put everything back and got a new battery. Seemed to have fixed the problem for a couple weeks. Then today go out to start the car and the same thing. Car won't turn over...pop the hood a little tap on the starter and it turns over just fine. Same cycle all day...Turn off car, then wont turn over unless I tap the starter. So I take it out again, and take it to the local auto store...Starter passes again.
It seems like it must be the Starter if the tap works, but I thought the bench tests were pretty accurate? All the cables and connectors look to be in really good shape and if it were the Starter Relay, Alternator, or Battery I wouldn't think that tapping the Starter would make any difference.

A couple of weeks ago there was a discussion about a car that smoked badly when it started. The boys recommended trying some oil additive that might avoid a ring job. What this product was?

I was trying to get my power windows on my 99 camry to work, so I tried switching some relays to see if this was the problem. I left the horn one out due to breaking it. The relays are not labeled other than the starter one. Anyway, my car will crank but not start. Acts like the timing is out. That belt was replaced 19000 miles ago...

My 2008 camry with 84000 miles is starting to use a quart of oil every 3,000 miles. Inam told that this is the beginning of the end. Can't I just keep adding oil? Or do I really need a new car/engine?
