Elantra HD (2006-10) :: Low Gas Mileage, Thermostat Stuck Open?
Jan 28, 2013
It's pretty cold these day where I live (about 2 weeks of -20C and lower). I know that winter can affect gas mileage but right now, I'm averaging about 13l/km (18mpg). I believe this is not normal.
I just bought the car and I noticed that the engine temp looks low to me (see pic attached). Is it supposed to run this cool? I also went to the garage and he checked with a obd2 scanner and nothing was wrong. Could a stuck thermostat be the cause of my poor gas mileage?

I have a 2003 Camry 4 cylinder and the thermostat seems to be stuck partial open. Gauge does not reach what was normal operating level before. Has not thrown P 0128 code yet. I was thinking changing the thermostat. When checking on replacement it shows 2 gaskets, one paper or rubber gasket with holes and an one o ring. Is this correct and if so where does each go when installed. Looking at the housing it does not look to be to hard a job.

If I don't replace it, will it cause any trouble?

I just got my 2009 Hyundai elantra GLS and realized that I can't tell when the car is heated, I usually like to watch my thermostat before I start driving, how do I know if its over hearing?

I have a 2008 Elantra with 50,000 miles. I know I was overdue on the tranny fluid change and the car was getting bad gas mileage and skipping gears. I brought it in and had the tranny flushed and refilled and now its running good. I thought it would be good to get a price on spark plugs because the book said replace at 60,000. I called the dealer and he basically told me he has not sold many of the plugs and they should last 100,000.
I seem to be getting conflicting info on what should and should not be done at the maintenance books written schedule. I looked for a price on Fuel Filter air filter which is in the maintenance to replace but again conflicting info stating that should not be changed unless there is a problem. Anyway, what should and should not be replaced at specified intervals? I know the tranny fluid change should have been done at 30,000 because it was very dirty and causing issues for me.

I have a 2009 Hyundai Elantra SE, and up until very recently I've had no issues with it, and am very happy with this car. About 2 weeks ago the malfunction indicator light came on. I checked the manual and it said to contact the dealer ASAP to have it checked out, but the car will still run. I've been terribly busy, and this is the first chance I've had to bring it in, so that's the plan for tomorrow. What this could mean, and will any necessary repairs be covered until the 100,000 mile warranty? If there is a repair needed that isn't covered, I definitely don't want to take it to the dealer!
Also, a few days after this light appeared, my gas mileage has been horrible, apparently. I say apparently because the digital mileage range now tops out at 255 when my tank is full; it used to be 336. It costs the same to fill it, and takes the same amount of gas, about 12 gallons. The gauge goes up to above the Full line, but I seem to go through gas so much quicker. Today for example, a trip that normally would cost me maybe $10 in gas, at the most, cost me almost $20. I haven't noticed any leaks, so perhaps this is related to the indicator light?

Today I was going to wash my car and rolled my driver's window down on the way there. When I got to the car wash I attempted to roll my driver's side window back up. It nudged ever so slightly up about a quarter inch and then nothing. It had totally stopped. I fiddled with the switch and it would go back down completely but when attempting to roll the window back up it would sometimes not move at all, move ever so slightly or move just about a quarter of an inch and stop. Is it possible to just get the window up manually in order to at least block the elements? I'm at a bit of a loss as to what I should do. I'm tempted to run to the drug store and grab some packing tape to seal the window off.

The lock on the rear driver side door doesn't work, it stuck on lock position and it won't open with the remote. You can't even turn the lock by hand from inside. It's like it's jammed or something. The rear passenger door lock was broken a while ago, it was making a nasty noise but still working so I had it changed but this one just stopped working.
How am I gonna fix that. I was thinking in order to fix the lock, they have to remove the door panel first, and to remove the door panel the door should be open to get to the screws. Is it gonna be stock for ever ?

Not sure what I put in there but can't get it to open. It slides back but it does not lift up. I could peek through and see that nothing's preventing from lifting up the are rest so I'm thinking it's something in the top bin that's getting it stuck. (maybe phone charger cable?)
How I can fix this. The top cover is air tight so I can't even see what the problem would be.

My thermostat is stuck closed so it needs replacing. I searched and couldn't find a DIY but there was a thread that says you need to take the whole front end off?

I have a question regarding a overheating problem I have with my 99GLS V6. I had the dealer do a timing belt, water pump, thermostat etc on my Passat about a year ago. I also have coolant leak in the metal pipes under my intake, which I haven't had a chance to tend to yet. I noticed recently that my car overheats and there was alot of pressure built up in the hoses. If I remember correctly, the thermostats are designed to fail in the open position. So I am wondering because of the leak, what's the chances that my thermostat could have failed in the closed position? I'm hoping its just air in the system and lack of coolant is causing this. It's been more than a year so I'll have to cough up the dough for this one.

In my 2010 Elantra, I have the 2 cup holder in the middle with the flap/lid cover that retracts into the side when opening. It seems a pen has gone down in that groove so now the lid does not open enough to get a drink into the holder. Any tips on getting the pen out from the bottom of the channel where the lid folds into??

My Phaeton has been running perfect since I got it. Yesterday I took it to the dealership to get fluids topped off and a wash. We have had a break in the weather the last couple of days, so I took my w12 on 465 and got it up to 120 before I chickened out. It continued to ride perfectly. This morning when I went out to start my honey do list the service engine soon light was on, it is still running perfect, but when I stopped by local auto store and had them pull the code it says "thermostat heating control circuit open". My middle temp stays at 200, when sitting still the left temp gauge goes almost to 200 however when driving it falls to under 160.

If the thermostat ain't opening and is stuck shut, will the temperature gauge climb pretty quickly? right? I am in the process of flushing my radiator.
- I drained radiator, changed the T-stat with new OEM one and then filled with distilled water. (Ensured the jiggle valve is at 12 o clock)
- I idled the motor with cap off, heater on and purged the system of air... topped off with distilled water, waited till the fans came on etc...
- Temperature gauge reads in the normal range... even after 15 mile drive...
But, I expected the water to mix with old coolant left over and change color that hasn't happened... hence wondering.

My 2010 elantra's trunk has been popping open for no reason, probably at least twenty times since I bought it last december, usually while I am driving. Hyundai service says they've never heard that complaint before. I'm wondering if it has something to do with the remote being activated by something other than pressing the button? While I'm driving the remote is usually dangling off the ignition along with some other keys.

I've a wired problem, my Elantra 2008 gas pedal is being stuck on the first push down only, when the car parked for more than 3 hours for example, the first press on the pedal i feel it very hard then it accept the pushing with a sound as if something is stuck and got released, after the first push it become very normal till i park it again.
I greased the pedal but noticed it may be the throttle cylinder at the engine where the gas wire is going around, i tried to accelerate the engine by turning this cylinder and it is being stuck at the first then is loosen, i tried it spray it with WD40 but it is the same.

Doing a rear brake job on my 2008 elantra. Left went fine. However, the right rotor is stuck on the parking brake. It is loose, but held on to the springs of the parking brake.
How do you back off the parking brake? Also, how do you remove the parking brake cable?

My hood has ceased to pop open when I pull the latch from the interior release. I removed the panel to see if the cable came undone from the release lever but it is still intact. From what I can tell, the cable seems to be snapped in the middle. I brought the car to 2 different mechanics, both said they would have to do damage to get under the hood. But I've read online and it seems other people are able to do it.
