Sonata I45 (LF 2015+) :: Auto-hold Making Grinding Sound While Releasing

I have a 2015 Sonata 2.0t limited with 12k miles. Just few weeks back I started hearing a noise when I would step on the accelerator after a full stop, when the auto hold feature was turned on.

With the auto hold feature off and my foot on the brake, I don't hear that sound when I release the brake. It only happens when the car is stopped and the auto hold is on and i step on the accelerator.

I took it to the dealer and he is saying the brake calipers need to be cleaned up. I'm not convinced it's the brake because I don't hear the sounds when I don't use the auto hold. What can I do to fix this?

Sonata I45 (LF 2015+) :: Brake Grinding Sound When Turning Wheel To Left

When I move the wheel to the left, I get this metal grinding sound (similar to rust on brake rotors/worn down brake pads). It happens when the foot is off the brake and ONLY when the wheel is turned to the left.

Sonata NF (2006-10) :: Rattling / Grinding Sound During Acceleration

I have a 2008 Hyundai Sonata GLS 2.4L with 131,000 miles on it. When I accelerate from a stop, there is a buzzing/rattling/grinding noise coming from the engine bay of my car. It's really hard to describe, there is a definite buzzing sound, but also almost like there is a bolt rattling around and banging into things. This only happens for a couple of seconds. It also seems to be worse when I'm accelerating up hill. If I accelerate slowly from a stop, the noise does not occur, and it also does not occur if I accelerate while I'm already moving.

Sonata NF (2006-10) :: Grinding Metallic Noise For A Few Seconds - Clutch Pedal Way Down?

I'm at my place in Florida 1,000 miles from home, and when I started the car in a mall parking lot, there was some grinding metallic noise for a few seconds and I couldn't get it into first or reverse and the clutch pedal was way down. I was able to get going in 2nd and eventually the clutch was back to normal and I could get 1st and R. What happened? Broke some fingers in the pressure plate? Seems to run fine now but have a 1,000 mile ride ahead in the morning.

Sonata I45 (LF 2015+) :: Metallic Click Noise Coming From Rear Cargo Area

Experiencing a metallic click or something alike when coming to a full stop?

I've notice this new noise and it seems to happen about 0.5 seconds after the car has come to a complete stop, not during the stopping. It only happens when stopping at a red light, and it doesn't do it on stop and go traffic.

It also doesn't seem to coincide precisely with applying the brakes because is AFTER the car has stopped, again, in less than a second. I hope that makes any sense.

It happens maybe 25% of the time but, then again, if I go to the dealership I'll probably won't be able to reproduce it.

Prius (2004-09) :: Metallic Rattle Sound During Acceleration

I'm back with another question! My 2006 Prius now has 60,XXX miles and the other day while driving with the windows down, I was climbing a hill to my house and when the engine is at a certain RPM, there is a metallic sound that comes from under the car, but more in the front. You can't even hear it when the windows are up barley, but more when they are down, you can hear it, especially when you're beside a wall or guard rail and the sound can reverberate back.

Sonata I45 (YF - 2011+) :: Metallic Rattle Sound At 2k RPMs

So on my new 2.0T Sonata I noticed a brief metallic rattle in the 2K-3K RPM range when you rev the throttle. I was very concerned.

The sales rep said it may be the heat shielding that is coming lose. He was concerned and said to bring it back when Service is open.

I just got back from the dealer: The service manager didn't know what it was but his tech said it was part of the turbo system, it's a 1/4 inch bar (parallel with the bumper) you can plainly see between the firewall and engine. He said what it did but I forgot to take notes.

I listened to another 2.0 Turbo Sonata on the lot and it has the exact same rattle when rev'd.

Sonata I45 (YF - 2011+) :: Engine Damaged - Metallic Pop Sound While Driving

I own a 2011 Hyundai Sonata with ~40,000 miles (certified pre-owned). I heard a metallic pop sound while driving but did not see anything on the road or in the rear view mirror. Then I got on a highway and couple of minutes later there was no response from the engine (i could feel the car decelerating). Then the engine started responding again. A couple minutes later, again there was reduced response but this time I got a bunch of lights (oil pressure, abs and a few others). I pulled over and tuned off the car. by this time only the oil pressure light was on.

I checked the oil which was near empty. I walked to a nearby gas station and bought oil and filled 2 quarts. Then I noticed that all oil was draining right through in a steady stream.

I had the car towed to a nearby Hyundai dealer. The dealer diagnosis was that there is no drain plug which may be because the last place the oil was changed (around 2-3 months back) did not install the plug properly. He also said that the engine is ruined and will have to be replace and asked me to contact my insurance company.

The last oil change was also done at a Hyundai dealer (a different one than the one that provided diagnosis). I checked my driveway and there are some oil stains, I haven't driven the car much recently and have recently moved into this place so am not sure if these are new or old. What are my options. I don't have the the thousands required for a new engine.

Sonata I45 (LF 2015+) :: Difference In Acceleration Between Sports And Manual Mode?

New Sonata owner. Got myself a 2015 Ultimate. Is there much difference in acceleration between "Sports Mode", and just running the car in manual mode (shiftronic)?

I know my Elantra used to have a huge acceleration bonus if I ran it in manual mode. Not sure if that caries true here.

Sonata I45 (LF 2015+) :: Hesitation Upon Acceleration And Check Engine Light Came On

I bought a pre-owned 2015 Sonata Limited in November. I only had less than two weeks before the car hesitated upon acceleration and the check engine light came on. At the time, I thought it was a loose gas cap as I'd just gassed up. I took it to the dealership, they pulled the code and it said to replace the accelerator pedal. That required a second trip to the dealership 2 weeks later when they completed the work. Two weeks later and the light came back on. I took it back and asked them to keep it until they found and fixed the root cause while I took a loaner. They kept the car about 2 weeks and when I picked it up, I found that no work had been completed. Two days (!!) later the light came back on.

Sonata I45 (LF 2015+) :: Engine Starts Hesitating Around 5k RPM Under Hard Acceleration

I'm on my second '15 Limited Turbo. Only have 2k miles, but I've noticed an issue with acceleration. When under hard acceleration, especially in 3rd or 4th gear, around 5k RPM the engine starts hesitating. It feels like it runs out of steam. This feeling lasts through beginning of next gear, then the car picks up again. It is actually faster when applying less throttle.

What it could be? It did it since new, I took it to the dealer once, but got some stupid response that it was just rev limiter kicking in (at 5k, right), unfortunately had no time to leave it with them again/show it to them. I also thought it might just go away on it's own, plus I don't usually drive it that hard anyway...

Sonata I45 (LF 2015+) :: Jerking Movements At Highway Speed Acceleration?

My problem is this: if I accelerate quickly (either flooring it or close to it), then once I reach about 55-65mph the car suddenly jerks horribly. Sometimes it's one big jerk, other times it's several small jerking movements. ECO transmission ...

It's not a problem at speeds under 50mph, but it seems once I cross that 50-55mph threshold, I can't put my foot all the way down or I will get the jerking. It will also occur if I'm going say, 60mph and need to quickly get to 75-80mph. The first time this happened, I was accelerating onto a highway and the car jerked so badly that I thought I had gotten rear-ended.

Sonata I45 (LF 2015+) :: Clanking Sound When Going Uphill?

I've been noticing a metal type 'clanking' sound whenever I am gently accelerating up a hill on my 2.4L.

It doesn't happen all the time though. It's not the usual GDI ticking sound. It can be heard when the windows are open but yet I can not tell where the sound is coming from. It doesn't happen enough that I can replicate it so I haven't taken it in for a check. The car drives fine though.

Sounds when going up a hill? Not sure if it's from the engine or from the transmission getting confused trying to change to the right gear. Perhaps the sound is just normal...

Elantra XD (2001-06) :: Grinding Sound On Initial Acceleration From Park / Scrapping Noise During Braking

2001 Hyundai Elantra, with an automatic transmission.

1. I am experiencing a "grinding" sound upon my initial acceleration from park? This only occurs when the car has been sitting for a decent amount of time and the engine is relatively cold. To give you more detail: I start the car, throw it in gear and begin to accelerate. The grinding sounds is almost instant and sounds horrible. It is fairly consistent how long it lasts and generally once the car shifts to 2nd or 3rd it goes away. I do not hear it again until I park, leave the car for a while, then start it up and begin driving again.

2. I am hearing a "tension" like noise, also a little like scraping, when I brake at slow speeds coming from my driver side front wheel. I recently had my brakes replaced so I know its probably not the pads and at the time the rotors looked fine too. It is not a constant noise during the breaking either meaning, I apply the breaks, i hear it for a second, then it goes again, then it comes back, then goes away. Again it sounds like a mix between scrapping metal and tension.

What it could be, what I could look at on my own or how to get it resolved?
