Elantra GD (2013+) :: A/C Drop Out On GT During Long Drives
Jun 8, 2015
Have had the following happen 3 times to me during longer (1-2 hrs) drives where I'm driving straight through, no stops, highway driving.
Running along fine when out of the blue, the A/C temp remains strong and cold, but the airflow drops dramatically to the equivalent of 1 or 2 bars on the fan dial. However, the fan dial remains at 5,6 or higher. Upping the fan dial does little to increase the speed of airflow. Adjusting the air source intake buttons changes nothing.
Only thing to correct this is to stop the car and let it sit, off, for about 20-30 minutes, or more. Re-start the car and it's all back to normal.
Searched the forums and can't find anything on Elantra, altho some Tuscon's seem to have had similar issue on older models, although their descriptions were more dramatic, w/the A/C going out w/in 20-30 minutes.

I have a base model 2009 Corolla and I find that on long drives (anything over an hour) the seats become incredibly uncomfortable. I have developed back pain I did not have before I bought the car. My wife drives an 05 corolla and I have no problems with it (even on 5 hour drives) so I can only assume that Toyota cheap out on the newer generation's seats. I have tried many different cushions, lumbar supports, and seat heaters, but none of them work all that well. Adjusting the seating position does not work either. I installed cruise control and while that worked a bit, it was no solution.

I have a 1999 chevy silverado 5.3 4wd w/ tow package. I bough it with 30,000 mi. It has always had a hard shifting/clunk after long drives or sometimes short ones that involve a lot of elevation. Oddly, if I stop and shut the car off for a minute or two the hard shifting stops, but eventually starts again. The truck now has 160,000...still with the shifting issue. What is this and with this many miles is it serious?

Noticed after long trips of a couple hours, the Prius rattles and creaks even when cruising in a parking lot at 5mph. I think it's kinda funny. That is, unless it doesn't happen to anyone else and there's actually something wrong with my car.

This is one of the strangest things I have ever encountered. when i start my car the climate control system works perfectly and it never has any issues driving around town. however for the past year or so every time i take a long drive over an hour and a half the force of the air coming out of the vents starts to diminish to the point where the only circulation i am getting is from the outside vent.
The strange thing is i can hear the fan blowing behind the dashboard and when i hold my hand to the vent the air coming out if very cold / hot depending on where i set the dial so it doesn't appear to be an issue with the AC or heater core .
I am thinking there might be some type of obstruction but that doesn't explain why the symptoms occur like clockwork on long drives.

There is roughly 800 on the odometer and I was averaging around 35 mpg. I filled it up and driving home afterwards I noticed the mpg drop off significantly. Now I'm lucky to get get 27. It was as low as 16 on the trip computer. The range was the same and the miles come off in sync with the odometer. I'm wondering if its a glitch with the trip computer?

Was typically showing at least 30-32 mpg but now around 30 around town, hwy 34-35. Just came back from hwy drive of 100 miles and the mpg showed 30 at the start and barely got to 34-35 which use to show and then it took the entire trip to get to that. The ECO is on....

I've had my 2013, 3k miles Tiguan for 6 days now and I love it. However, I live in NW Connecticut, and it's hilly. I've noticed that when going down hills, the car will drop to a very low gear all of a sudden, and shoot up to 3-4k rpms. It has me really worried.

I've had my 2013 Prius for 2 years...first time that I've heard 5 beeps while driving, has happened twice this week, both times after 2-3 hours of distance driving. It's never happened before. Done some research to no avail.

I have a 2003 Elantra, which I've had for several years, and love greatly. Recently though, she's been giving me problems.
When it first started happening, about 6 months ago, it seemed that she was simply sluggish, and wouldn't accelerate as well as normal when I pushed the gas.
It has gotten worse from there, within the past 4 months, sometimes when I turn her on, she idles very rough, and the entire car shakes. Originally when this started happening, if I turned her off and back on, she would run smoothly again. Unfortunately that's no longer the case.
If I attempt to drive anywhere when she's acting up, pushing the gas makes the RPM drop down, and she doesn't move. This has caused a lot of problems at stop where I'm turning onto a busy road. Occasionally when I'm driving around, her RPM drops far below what it should. For example, she frequently drops down to 700 RPM when I'm driving 35 mph... normally when going that speed, the RPM is about 2000.
Most troubling to me is the fact that the engine turns off on me without warning sometimes. I've had her do it when I'm at a stop waiting to turn, at stop lights, and dangerously, even when I'm slowing down through traffic or getting ready to pull into a parking spot.
I've tried multiple things, fuel injector cleaners, replacing temperature sensors, and I've checked all the valves, wires, and hoses. I've had it attached to a code reader and of course she never acts up while it's attached.

Can't run a/c rpms drop to almost 200 from 1200-1500rpms. Really bad when at at traffic light. I have to constantly press gas pedal.

When the temperature drops below -20 Celsius, I find the transmission shifts weird just after start up. It seems like it goes into second, then third normally, then abruptly drops back into second. I'm pushing very lightly on the gas pedal, so the drop down is weird. A couple times the nav was blank on start up.

Started having a key issue: while in the car, intermittently, get a "key out" error with accompanying long beep as if you walked away with car running. This happened while driving. Changed the battery (key fob-keyless limited elantra 2011) but still did it. Not all the time, unpredictable. Got 90k miles, and not a covered entity per dealer...yes, not a power train component.

I own 2013 Mk6 GTI. I am having to over crank the engine for a period of 8 seconds or so before the car starts, especially after it has been sitting for a few hours. My thought was a faulty check valve in the fuel pump. I have heard that our fuel filter has a built in pressure regulator that may get stuck open for whatever reason and that may also cause a long crank time.

My nephew's car is a 2002 Hyundai Elantra GLS manual. His RPM's hang when he shifts and it is a pain to shift.
I took it to the dealer and had them do TSB#04-36-011 Delayed RPM drop between shifts. This TSB supersedes TSB 01-36-025. Here is a link for the newest TSB : [URL] ....
The TSB Basically tells them to erase ECM adaption values. Then, you update the ECM with new FUEL cut-off logic. When we drove off the dealers lot the delay was not better, just different.
After driving it for a day or two we saw improvement. Now when you push in the clutch the RPM's go up slightly for a second to burn off the gas then the RPM's drop faster than before.

Why all of a sudden the mileage indicator on my 2012 suddenly dropped about 5 miles/gallon, both highway and around town? The car has only 9000 miles on it. Has there been a service bulletin regarding the "Eco'" mode? Having the "Eco" mode on or off doesn't seem to make a difference.

2013 2.5 liter. I took my car into the dealer for a grinding noise on cold start. Sounds kinda like the starter was engaged too long, some sort of grind that only happens after the car has been sitting for a few hours.
They replaced a camshaft VVT-i gear, said it's fixed, and now I swear the noise is louder. Is this just something to consider "normal" for the 2.5 liter engine?

All of a sudden my fuel consumption dropped from 28mpg as read from the computer display in the dash, to 21mpg. This was not a gradual drop, it was at 28mpg one day and 21mpg the next day. There is no service light on, do these cars produce codes that don't trigger the service light?
A few months ago the vehicle was getting stuck in various gears and lunging, this was from battery corrosion dripping down and eating away at the transaxle range sensor. I cleaned up the battery and replaced the range sensor and the vehicle was driveable again. It re-learned the shift timing and seemed to be ok, then about a month ago it seemed to be forgetting the learned shift positions after sitting over night, I replaced the battery, thinking it was in a marginal state where it would forget the program while sitting. The shifting is still hard sometimes but this seems to have worked but, now my mileage is horrible.
I thought I'd just change out the oxygen and air flow sensors but, then looked at how much they cost now, and realized this would be some costly trial and error. Is there a methodical way to troubleshoot this issue, any way to pull the sensors and measure them?

I am not sure if it's my imagination or not, but my car seems to be running differently lately.
When the car shifts into 4th the Rpms seem to drop kind of and the car seems like it is bogging down. Not extreme, but I don't remember this when I first got it. It's like I really have to accelerate when it shifts into 4th or I cannot pick any speed up.
Is it because the motor is now broken in? It has right at 8,000 miles now. It's due for an oil change, but I wouldn't think that would have anything to do with it !

I am currently about 1700 miles into what is a, planned, 11,000 mile road trip up to Alaska and back to SC. The first three days of driving everything was fine and I was getting 33 MPG. Today my MPG dropped down to 28 and in the evening my check engine light came on. The folks at PepBoys told me it was P0139 which I understand has to do with oxygen sensors and would affect my vehicle gas consumption.
If I drive about 21 hrs (Denver to Portland OR) to get to a place where I have a trusted mechanic and more free time, will it be bad for the car/engine?
Driving: Elantra GLS, 2003. Around 53k miles on it. Just replaced the tires last week as well as all belts (including timing). A few years ago I recall a similar error and my mechanic had me take the car to a muffler shop to cut something out and reweld it. yeah, I have forgotten the details.

I had to make a left hand turn very quickly into a gas station. I moved in 1st gear and accelerated quickly (went around 3,200 RPM). When I stopped in the parking spot, clutch disengaged, brake pedal engaged, the engine was still spinning at 3,000 RPM!!!! I waited until the engine calmed itself down to idle RPM but it was stuck at 3,000 RPM.
Something wrong with the accelerator? I put the car back in 1st gear and rocked forward a couple of inches so I can put a load on the engine. I put the gear back in neutral and the engine calmed down to idle RPM. Something was stuck? Bad computers? Bad design?
