Lexus RX 2010-15 :: Loud Knocking Appeared With Check Engine Light
Started up our 2010 RX 350 and there was loud knocking. This smoothed out after several seconds. I stopped engine and started it again. This time the knocking was less severe, but now the Check Engine light is on. Engine seems to be running a little rough as well. I have a feeling I have a bad plug or wire maybe.

So my 2012 plugin was parked for about 3 days, and when I turned it on, heard loud knocking and the check engine light came and stayed on.
When switching the car on or off, I'll hear two taps/ticks that were not there before. Loud knocking is not there now.
What can the issue be? It was very cold and snowing.

I know all Hyundai's 1.8L Nu engines have that quiet ticking noise. But is there a slight knocking sound on the left side of the engine (around the belt area)? Could this be just the timing chain noise? It does this on idle but when on a constant speed/rpm, the engine is quiet.

View 4 RepliesPrius (Gen 3) :: 2010 Engine Clatter And Check Engine Light Came On
Started my 2010 gen 3 Prius 3 the other day and got a bunch of what I thought was engine clatter and the check engine light came on.
The next time I started it, no noise. Anyways brought it to dealer and they diagnosed it and ordered a new manifold.
The next day when the part arrived, I brought in the car. Talked to the mechanic, a great guy, and he explained what happened. Apparently, the clatter is actually the springs rattling in the clutch mechanism of the starter motor/electric motor and not the valves like I thought.
Volvo :: 2007 - Rattle Sound / Check Engine Light Came On
I have a 2007 XC90 3.2 RWD with around 112,800 miles.
On acceleration, there is a rattle (not a valve knocking) that gets quieter once a steady cruise is achieved. At idle in gear, a very quiet rattle can be heard. When transmission is slipped into neutral, the rattle goes away. The engine shifts normally, accelerates normally and gas mileage is steady at around 20.5 mpg (mixed city and highway). I am using 93 octane gas. This week the check engine light came on.
Silverado :: Check Engine Light On / Sound Skips On The Radio
First of all, its 5.7L V8, it's been very well maintained, I've had my fair share of problems but nothing that has been that serious, except for the "check engine" light for the O2 sensor.
For about the last 4 months i've had the problem of the truck sometimes jerking while on the road. Once i started to speed up it seemed to not speed up which when it did, it jerked a bit. That was in the beginning.
AS OF NOW, the jerking has stopped but every now and then when i pull out of the garage and start to turn onto road it turns off, but all the status lights are left on. & when turn the key to turn it off and restart it starts again every time. Ive noticed that i was better off with the "check engine" light on then now because every time it is off it has these problems.
Also, when I barely start to tap the brake, again not all the time, sound skips on the radio. & this always happens when i tap on the brake & this happens more frequently when the "check engine" light is off.
Lexus ES 2007-12 :: Check Engine Light Came On / Low Hissing Sound
Was driving back home and the check engine light came on, these are the codes I got:
P0345: Camshaft Position Sensor "A" Circuit (Bank 2)
P0365: Camshaft Position Sensor "B" Circuit (Bank 1)
P0390: Camshaft Position Sensor "B" Circuit
The car drove fine, didn't feel any power loss, I heard a very very low hissing sound but I honestly don't even know if it was always there or not... I did put some gas from a different station for once, so I doubt the fuel caused this?

I'm due to leave at 6am sharp on Friday morning for that pre-planned surprise 50th Bday celebration I've been talking about for my wife. This evening I get in the Elantra to pick her up and when I started the car it began to shake VIOLENTLY, like I was in a commercial dough mixer. WTF!?? I saw the check engine light was on so I shut it off immediately. Curiously, I had the car out earlier without incident.
I restarted the car and it ran smoothly this time, but the check engine light remained. Calling the dealer, I was able to get a 9am appointment for tomorrow morning. I don't have an OBD-II scan tool to check the codes, but based on the symptoms, and recent poor gas mileage.
Elantra MD (2010-15) :: Check Engine Light On Then Off
So the check engine light on my '12 with 5K miles came on 2 days ago. Called to make an appointment at the dealer for tomorrow...and today it goes off. Is it relatively safe to fore go the appointment and see what happens? I don't think it was related to the gas cap.
View 2 RepliesElantra MD (2010-15) :: Check Engine Light Comes On And Off
I just bought a used 2011 Elantra GLS and am having some issues that the dealer cant resolve. What is happening is the the Check Engine light comes on and off. It will be on for a day or so, then go off for a day or so, so I am thinking its the gas cap. So I tighten that thing up as good as I can and pulled the negative battery terminal and problem solved. About 2 days later, and about 200 miles later on the same tank of gas, the light pops back on. So I call the dealer and took it there the next day.
On my way to the dealer, the light goes out. They try and pull the code, but the ECU is showing nothing. I asked if the ECU stores codes and I was told that when the light goes out on its own it clears the ECU of the code. Not sure if that is true, but that is what I was told. So I drive the car home. I fill the car with gas, drive about 100 miles and the light comes on. I call the dealer the same day, take it over, and on the way like the car knows it goes off and guess what? Dealer cant do nothing.
Now to make a long story longer, this is what I know. The car is not a CA car. It was sold in GA and was a prior rental. It ended up in CA and was sold as a certified pre owned from a Hyundai Dealer, I actually bought the car from a Mitsubishi Dealer and they dealer traded for this car (thats another long story) the carfax does show that it failed emissions but passed after several attempts. Which I thought was odd on a ULEV vehicle. Since I liked the car so much and the price was good, I bought it since it did pass smog eventually.
Once I get the car home, I do my usual thorough look. I clean everything to my standards. I am cleaning the engine compartment and took the engine cover off. 1st thing I noticed was the Spark Plug Coil Packs all the 10mm bolts that hold them in were loose and 2 of them were completely off!! So I decided thats odd, so I pulled the plugs out and they were the NGK's so just in case I put a brand new set of the NGK laser Iridiums back in and tighten everything up. Then I notice where the PCV valve is on the valve cover, the hose that goes to that to the intake tube does not look stock. The hose looks like fuel line hose that someone put on it and the clamps are not stock. So I am canvasing for OEM replacements of those parts now. Then when I was installing the mud guards, on the drivers side rear tire where the gas filler tube is I notice another non OEM clamp. So someone was messing with this area of the car too.
The car is averaging 26-28mpg's in the city and I have been getting 35-37mpg's highway so I don't think there is anything major wrong here. I believe that either the PCV valve hose is kinked and may be causing a fault, or that since it was a prior rental that people were over filling the gas tank and maybe blew the expansion valve in the gas tank, causing the fault. I have no way to prove this since the light goes on and off and clears the ECU every time I take it in.
Prius (2010-12) :: Check Engine Light Came On?
Last Fri the check engine light came on so the first thing I did was check the gas cap. It was loose so I retightened it and went on my way expecting the lght to eventually go out. It was still on several hours and a couple of stops later so I called my dealer and explained to my service rep what was going on. He told me to give it a few days and to call him if it didn't go out by today. He said it takes a few days for the computer to reread the system. So we drove it all weekend and it finally went out this morning (Tues). With just under 145000 miles I'm wondering if I should get them to put it on the scanner anyway. It's$130 to do the scan so it's a bit of a ding in the budget. Do the hybrid batts need to be checked,indicator light or not? Here in Ca I think they have a 150000 mi warrenty?
View 15 RepliesPassat (B6) :: Squealing Sound At Low Speeds / Check Engine Light Randomly Comes On Then Off
First, my g/f and I love her 2.0T, but lately a few things have started to bother us.
1. Strange, rhythmic squeeling at low speeds (like a bearing or warped rotors) that goes away when the brakes are applied.
2. Driver's seat is rocking back and forth under heavy acceleration and braking. I hope it's just a loose bolt and not a crack in the floorpan.
3. Check engine light randomly comes on for a day or two then goes off conveniently after we schedule an appointment with the service department.
What might be causing these issues?

Lexus RX 2010-15 :: Check Engine Light Came On - No Oil On Dipstick
I have a 2010 rx350 and had a big oil leak recently because the car shop didn't install correctly the oil filter seals. It didn't leak right away and my wife drove till the check engine light came on, but it was late... no oil in the dipstick... I think no oil at all but the car didn't display low oil level warning. only a beep when i turned the steering wheel.
I had it towed and luckily my wife stopped the car when the light came on, no harm done the mechanic said. But I think it has less power and the engine noise is a little louder than before..., so maybe the engine has a Little wear. but there is no smoke. Should I continue to use the same thin oil.. 0w20. or use a thick like 5w30??
Prius (2010-12) :: Orange Check Engine Light Came On
I have a 2010 gen 111 with nav system etc, the other day a orange check engine light came on, I took it to our Toyota Dealer and they said that I had mud and gravel up in the car, near the fuel intake area, and that the carbon capture canister/switch was damaged by the dirt and I need to get it replaced. I asked if I could simply not make the repair due to the fact that the electronics system would eventually not be able to read the H Carbon readings and the car would burn more fuel.
