Good Evening All,

Changed the battery on a 2019 Sonata after the weather dropped to a 10 degrees and the vehicle wouldn't start after a day out in the cold. Old battery tested at about 10 volts, new battery 12.7. The car will not even attempt to turn over now. We try the push start, it doesn't even attempt to turn over. Battery light is still on. Lights turn on as do headlights. Any thoughts? Thank you in advance.

Has anyone had Hyundai replace their hybrid battery under the lifetime battery warranty? Our 2012 Sonata Hybrid Limited with 164k mile started throwing the P1B74 code. So I took it in. The dealer ran diagnostics and said it was the battery pack and battery management system. Got Hyundai to approve warranty replacement of both. They have ordered the parts and the battery. No ETA. Until then, I will be driving a 2024 Elantra loaner. Dealer said could be 3 weeks, could be 6 to 9 months. They have no idea.

Anyway, my questions are for those who got the replacement battery packs, what improvements did you see? I was still getting 32-37mpg, but battery was never going over 1/2 to 5/8 charged. Thanks and sorry so long.

We have been looking at a 2015 with 42k miles, well taken care of as far as oil changes and what not…. I am aware of the engine issues and we are thinking about taking a chance with the car. During the test drive it started getting dark and we noticed the headlights flutter/pulsate. I don’t know exactly what to call it, they don’t go off, it is more like they change intensity, and not by much, it is just noticible. There doesn’t seem to be one thing that causes it, like turn signal activated or brakes applied, they just randomly change. Any idea what the cause could be? But back to the engine, recalls have been done, including 953 (upgraded sensor for rod issue), according to Hyundai, this qualifies it for engine replacement if the engine fails due to the issue.

Edit: I am not mechanic…. I did put a voltmeter on the battery when the headlights and seat heaters were going and got 14.4 volts I believe. Is there a better way to test the alternator?

100k miles. Prefacing this by saying that I was somewhat aware of the engine problems to come and still don’t know exactly what to do in my certain situation.

In the middle of a drive, my car started misfiring, with a flashing yellow engine light, bad engine sounds, and dying movement/acceleration. I barely made it into the AutoZone and asked for a code readout, and obviously, it came back P1326.

I get my car towed to the nearest Hyundai dealership and called them to leave a message. They called me back the next day and explained that the only evidence of the car breaking down was because there was no oil on the dipstick and my spark plugs were a little worn. I was confused and bummed out, as I was sure I had just put oil in it maybe <2k miles ago. Despite explaining to them that I'm aware of the lifetime warranty on the engine, they said there is nothing they can do, as my engine passed their bearing rod test, but assured me that my engine was covered when it dies. They charged me $300 for an oil change and new spark plugs and sent me on my way.

What should I do right now? Do I keep pushing them, or should I just wait until my car gives out in a potentially dangerous place like the highway or somewhere where there is no service? My question right now is: if they know the engine will fail, why can't they replace it now? I was getting the P1326 code, which is what qualifies me for the warranty, and they still kept saying my engine was fine.

Hey everyone

wondering if there are any Sonata/Hyundai experts who could let me know if the 2006 Sonata shares any interior parts/trim with any other model Hyundai from that era?

Fore reference, I'm searching for a passenger (LHS) sun visor, cupholder, and drivers door card trim (RHS).

Need Guidance -

I recently purchased a 2024 Sonata SEL Convenience and am quite pleased with it. However, it lacks a front camera and side mirror cameras, features that are available in higher trims like the Hybrid Limited.

I'm considering upgrading my SEL with these features by installing the front camera assembly and side mirror assemblies from a 2024 Hybrid Limited model.

I'm wondering:

1. Compatibility: Would these parts be physically compatible with my SEL model?
2. Software Integration: Even if I manage to install the hardware, how can I integrate the necessary software to make the features functional?

I have some basic car repair experience, but I'm not a professional mechanic. In the past, I have replaced car numbers, mirrors, head and tail lamps. But nowadays cars are more complex.

Any advice or guidance on this matter would be greatly appreciated.

Thank you in advance.

Started flashing the other day

UPDATE- Battery replacement fixed the issue. I’m almost at the 100k miles, it was the original battery.

Thanks for the suggestions!

Hello!

My 2015 Sonata Eco won't start. I took one kid to school this morning and everything worked great. About 15 minutes later, I was trying to leave the house and the vehicle wouldn't start. When the key is turned to ON, radio, wipers, lights, everything are functioning. But when I turn, it doesn't properly turnover and behaves as you see in the video.

Any ideas?

I use to drive a 203 Sonata GLS, and i absolutely loved the sound the car use to make when you maxed out the Gauge cluster lights. Can someone upload a small video of that sound? I tried finding it on youtube, lol.

Hey everyone, I have a 2016 sonata SE with 2.4l and it’s been consuming more and more oil lately. Can the engine be replaced for free or do they only replace if the engine is damaged by the bearing thing? The car has 135k miles

Hi I bought a used hyundai sonata from carmax roughly may 31st and within the limited warranty I went to check my oil and found no oil. I took it over to carmax who then took it to Hyundai and they said cracked oil pan. Replaced it no charge, however I then started the oil consumption testing process. They filled up my oil, said drive 1000 miles and then come back. I did and they said "hey oil consumption is still too high lets clean the combustion chamber". They filled up my oil, drove for 1000 miles, and then dropped it back off.

Now comes the reason for my post. Hyundai is recommending a new engine (car has 91517 miles last I had it, bought it at like 84k) and they are unwilling to pay. Carmax is saying while they will pay for the replacement, they got cold feet about a new engine and are wanting to instead use a "used" or "remanufactured" engine. Has anyone had experiences similar to mine and if so what happened?

I have a 2014 Hyundai Sonota limited hybrid. I love it. But I have literally never seen anyone with the same car.

Hello, sorry if this is a stupid question but just wondering if this foam thing is needed or not. I'm assuming you wouldn't want something that looks flammable right on top of the engine? But it has been here ever since I got the car. Is it best to just toss it out or is it protecting wires or something?

Title ^ first time installing a dashcam, can’t find one online for a 24 sonata but want to find a video / guide that is very similar/ worked for you for the 2024 sonata models

Hello, 3 Days Ago, the cabin of my car started smelling like shit. I have tried everything. I cleaned my car inside out. Car is perfectly clean but still there is a bad smell. The smell remains the same even if the AC or Heat is ON & OFF. There is no smell if u stand next to the car. U only smell it when u open the door. I even left the car doors open and window down for 2 hours but that has not helped at all.

What Should I Doo?

Hello, I have a 2013 Sonata Turbo 2000 engine. The problem is in the Gear system. When I go out in the morning in the winter, between first and second gear, the adjustment process is delayed and I also hear a sound in the adjustment. What is the problem and how to treat it? Thank you.

Has anyone found calliper covers that fit 2024/25 n line?

My 2018 Hyundai sonata has a very long crank trying to start and when it does start it runs fine until it doesn't, typically around a minute or so later it will bog and shut off and then will randomly run fine again and so on, and when it starts bogging and shuts off fuel rail pressure drops from 650-1100psi down to 30-50psi, only codes showing is a P035F, it will run on starting fluid, high pressure fuel pump has been replaced and same issue is occurring, throttle body has been cleaned, maf sensor has been cleaned, currently I am stumped

Any help is appreciated

What might cause a fob to stop opening the trunk, but it opens the door just fine?

The car is located in an underground garage where it is cold, but not freezing. The trunk opens fine from the mechanical button for this on the dash. It does not appear to be sticking.

After driving a short distance (to a grocery store), parking outdoors, shpping for about 15 minutes, the fob can open the trunk with no stickiness. The temperature is about 1 Celsius outside.

While I hardly drive these days, I have observed the above pattern a number of times in past weeks.

Apologizes if this has been asked but how do you update the radio on a 2017 sport? According to the navigator installer you need a SD card, but there is no port. I’ve also tried doing it on a thumb drive but it fails

So has anyone purchased a cold air intake yet for their 2024 Sonata? Will the 2023 models still fit the 2024? Any help would be much appreciated

I have the General Warning Light illuminated with the number 4, the following warnings are present:

• Check Smart Cruise Control System
• Check High Beam Assist (HBA) system
• Check Driver Attention Warning (DAW) system
• Check Lane Following Assist (LFA) system

I would think they’re all tied to the windshield top mount front camera? No fuses seem to be blown. Any idea how to try to reset or troubleshoot? I’ve tried unplugging the battery for an hour, and pulled all the fuses that were labeled “ECU” or “Sensor”.

I had to replace my front radar with a new OEM part as my daughter hit a traffic cone that damaged the front grill and bent the race mount back. That took care of a Forward Collision Warning error I was getting so I’m assuming the radar works, but now I have the above warnings.

Hey guys, Got a 2003 sonata that gonna need some breaks soon. First time trying to do them myself so I’m not too familiar with brands and just want something good quality that won’t wrap me around a tree. Would like a rotor set if possible also as I do believe they could also use a change.

installing a cold air intake and the stock intake has a box we can’t figure out the purpose of. any insight would be appreciated
