Sonata I45 (YF - 2011+) :: Engine Has Inconvenience Starting Only During Cold Weather
Dec 22, 2015
So I have a weird situation. My Sonata GS with the 2.4 engine has trouble starting ONLY during cold weather (-2 or colder) if it's been sitting for a few hours. If the weather is warm, then it starts fine most of the time. The car tries to 'fire' for about 45 seconds before it does; and 'fires' with no hesitation at that point. The car runs fine, no hesitation or rough idle. I've cleaned the intake system to make sure it's not clogged or dirty, replaced the air filter, cleaned the MAP and throttle body. My battery died a few weeks ago, so I've even replaced that. What this could be? Everything I've researched or looked into would throw a code, or have symptoms while driving...yet it runs fine once it's started, and no codes/lights are showing. Don't want to just start swapping parts hoping to find the problem...

Had a really cold day here, got on the highway and from around 80-100 km/hr the car had bad vibration, would be unbearable for any extended time. I got up to about 120 and the vibration lessened.

My wife couldnt get her 2011 SE to start this morning. It engine turns over strong but it wouldn't start. Brake lights worked. Brake pedal very hard. Tried several times but would not start. Finally I jumped battery just in case and it cranked. Don't know if this was coincidence or not. Car is two years old and only 30k. I checked for interior lights being left on or other things that might drain the battery.
Could a low Fob battery cause this? Brake switch? No codes thrown. Taking in to dealer but wanted to rule out a simple fix.

2001 Intrigue 3.3 L v6
Due to the cold weather, seems the battery could not start the car. I removed the battery to trickle charge it overnight in the house, and hooked it back up in the morning. It seemed to have sufficient charge to power the starter motor, but the engine would not turn over. I could hear a whirring sound whenever the key was turned, and the sound stopped whenever the key was turned off.
I am suspecting that the starter motor somehow is not engaging with the engine flywheel?

I have a 2011 sonata with the 2.4 liter 4 CYL motor and auto transmission. It has 61,600 miles on it. Just out of warranty...awesome.
In the last few days I've noticed it has had issues starting. For instance, when I got into the car and started it for the first time in the day, it starts up fine. Then a few hours later, I start it again but the engine will just spin slowly...I then turn the key back to off and then turn it again to start. It then will start up fine on the next try.
No check engine light or any sounds I can feel (I am Deaf so I cannot hear any sounds when it doesn't start) new battery in August of 2015. When it doesn't start, all of the dash lights come on.

My Chevy Cobalt will not start in cold weather. I don't think bad battery is the case here because it's started in warmer temperatures. What could be wrong??

2004 Passat 1.8t that is intermittently not starting. The problem only happens when the car is cold. When I turn the key, the car cranks just fine but will not start. All of the dash lights light up and I had the battery tested and it is fine. Tonight it took about 5 minutes of repeated cranking and waiting before the car started.
After a 15-minute trip home and it had a chance to warm up, the car starts just fine. I've taken it to my mechanic but they haven't been able to replicate the problem. I'm thinking about leaving it overnight just so they'll be able to replicate it.
Not sure if it could be related, but I just had a coil replaced a few weeks ago (the coil was <1 year old). The plugs are only 3 months old.

My 09 Sonata LTD V6 was sometimes idling erratically (revving and slowing) after starting a cold engine. It never happened in the previous 3 winters I have owned it. I took it to the dealer for service and they said an ECM update was just released, described on the invoice as "TSB 10FL002 FOR COLD START ROUGH IDLE".

My 2006 Ford Fusion SE V6 has trouble starting in cold weather. Once it starts, it's fine throughout the day, but once it sits a long time, like overnight, it has trouble starting in the morning. If it had a carburetor, I'd say the choke wasn't working. The dealership couldn't figure it out a few years back. I even tried a new battery and that didn't work. Is there a sensor that detects cold weather and increases fuel flow or chokes off air flow for richer starting mixture that could be failing?

Lately, I've noticed that my car starts fine in cold weather. But, once I put the car into drive or reverse, it stalls. Also, once I start the car let my foot on gas for few min, and then put into drive or reverse, it drives fine.

How to diagnose what I think is a failing alternator?
Here are the symptoms:
- Hard starting in cold weather
- Battery not at full voltage when truck is parked (usually around 11.5-12 volts. I have been putting a charger on it some nights)
- Lights seem to dim when I've got accessories running, like heater fan, heated seats etc. Lights get brighter with engine RPM, like when pulling away from an intersection.
What's my next step to diagnose this? I did a search, and didn't see anything. My battery is probably still under warranty, so if that's the issue, it should be a free fix. How hard is it to install an alternator in a 2005 with 5.4L engine?

Vehicle: 1995 960 wagon
Background: Exhibits intermittent no-start behavior in both warm and cold weather, wet and dry weather, having sat overnight, or only sitting a few minutes. Turns over fine, but won't start. Sunday, it started fine several times, went to Home Depot, wouldn't start. Called a friend to pick me up. When he was almost there, I tried it again and it started back fine. Been in shop a few times, they played around with a few electrical connections, battery cables and grounds to injectors. Also replaced fuel pump. I have not verified if it is a fuel or spark problem, I just bought a FI fuel pressure gauge last night.
Once started, it does fine. It never stalls or cuts out. That is why I am leaning toward a CPS (that's what jeep people call it.) Sometimes, under the slow cranking speed (relative to idle) the signal is too weak to be useful. However, during idle and normal operation, the flywheel is moving fast enough that the signal is much stronger (being a magnetic pickup). Thus, the reason it only happens during starting, not during running.
Here's my current working theory: Bad crank position sensor (is that Volvo people call it?)
This is the only part I can think of that would cause this. A fuel pump problem would probably show up during running. I think the pump also receives a signal from the cam sensor, so if that sensor were the problem, it would happen during running too, not just starting. It the cam sensor an optical sensor? Shouldn't cause it to not start, although it might cause a difficult start.

My idle seems to always be somewhat rough whenever I put the heat on in cold weather. While in drive I'll come to a red light, heat will be on and I'll stop. The. my idle will bounce down then back up. I shut heat off to test and it only does it while heats on.

I have a 2011 Avalon Limited and live in the Dallas area. Are used the auto setting on my thermostat all the time. I noticed that in cold weather, the AC almost always switches on as part of the thermostat function. I don't understand that. For example, its 30 degrees outside, & I select Auto and set the temperature to 70 degrees, and the green AC light goes on. I want to avoid using more gas than I need to use, so I'm wondering why this might be so. It's a simple matter to simply press the AC and turn it off, but I'm wondering why it goes on in the first place.

Ok so I replaced my upper strut mount and my struts in the front along with the shocks in the rear.......... the squeak is still present when i go over a rougher bump and it is cold ..................SO i went on hma service and saw this...................
Symptom "Squeak or grunt-noise from the front suspension, occurs more in cold ambient temperatures-more noticeable over rough roads or when turning"
Suspect Area "Front stabilizer bar"
Remedy "Under these conditions, the noise is acceptable."
Wow so not acceptable i am going to try and lubricate this piece... Will report back

Noise question. I have a 2011 super duty f250 xlt, and my question is I have a grinding noise that does not sound metallic and only shows up when its below freezing, only in drive and for about 50 yards.

Yesterday I took my car out, stopped at a gas station and the car wouldn't start. When trying to start it, everything inside would come on but it would just click. We were able to jump start it. After that I was able to start it 2 more times. the next time i tried to start it, it did the same thing, but the jump didn't work. We went and bought a new battery and it still isn't starting. It isn't clicking anymore though. It kinda hums when it tries to turn over. Does this seem like a starter issue?

I was heading home last night from work and noticed something odd. It was the first pretty cold night that we have had around 20-25 deg. and I took off from the parking lot like normal.
When I got to the first stop light about a mile down the road I heard what sounded like the engine revving up right when I took my foot off the gas pedal. It did this as I coasted to the stop light. It also did it again at the next stop light just up the street. I thought maybe it was the heater blower, but It really sounded and felt like the engine revving. The car did not accelerate or anything, is this part of the warm up or normal? I also have the lower grill blocked but I don't see how that would make any difference.

Went on a trip up to MI in cold and snow, and the engine light comes on. Great, I'm thinking, figuring me, the wife and our two babies stranded in another quality VW product. We pull over and call the closest dealer on the cell, and they say to just ignore it unless its flashing. When I got home, I vagged it and it says the cats were below their operational limit - I'm guessing too cold?
Whats the deal here? Can I look forward to engine lights everytime I go out in the cold? (this car is slowly driving me nuts. How can it be so bad and my Audi so good?)

So I tried using a faulty cellphone charger in one of my charging ports. I heard a loud click and now my car is not starting. So, the first thing I looked at was the fuse for the start and engine, thinking they may have been blown, but that was not the case.... Where do I go from here?
I have a 2011 Hyundai Sonata 2.0T

I have a very intermittent problem when starting my car. Usually it is when it's very hot outside, although not always. Start the car with the AC on, recirc, after about 3-5 seconds its a very loud "slide whistle" type sound (going from lower to higher, pretty high pitched). It only lasts about a second and sounds like something opening and creaking? Brought it to the dealership before, but its so intermittent that I doubt they tried very hard to find it. It probably only happens once or twice a month and will not duplicate if I turn off the car and start it again.
