This car has received regular oil change including filter changes and the engine has been flushed twice because each time the oil change miles have occurred the oil in the engine appears to be muddy. This car is only being driven to and from local city limits and only has 65,000. The car started braking down slowly with no explanation. 1st battery died constantly we put in a new battery, then the starter failed we replaced with brand new starter now the engine is completely gone. All in a matter of one month. Based on all the 1,000 complaints I have read on this particular car, all have experienced the same thing. Please this needs to be investigated

Purchased car and have had 3 recalls already. Car has need at dealership for a month now and they are unable to update when it will be available and what will be done to it. Also I checked the VIN number on VIN check pro and it show the car as branded on 1/30/2017 in Texas as salvage. It also shows branded on 04/25/2017 in Texas as junk. They Hyundai corporate office says they do show this on thier records. Could you please help because at this point I do not feel the car is safe for my daughter to drive. After the last recall was complete, the first time the car was driven the check engine light started flashing and the car had little power. It has been a T the dealership since then.

To note vehicle had a complete evaluation 1 week prior with no current or upcoming issues. Upon starting car "ABS light, traction light, bsd (blind side detection) light" came on. Upon driving, my bsd sensors did not operate, and engine made whistling sound upon acceleration and would not go over 40mph without the power being pulled from the engine. Also to note my car was apparently trying to be in a higher gear at 30mph (5th gear). All of this is very suspicious as the car has only been serviced at dealerships with most recent being 1 week prior. Service department seemed very poor at explaining the cause for the simultaneous malfunctions of all these systems. I do not currently feel as safe with this vehicle as I have before.

P0010 code and P0011 can hear a metal grinding noise when accelerating also fluctuating rpms. I keep immaculate maintenance and take excellent care of it. Absolutely no idea how but parked car everything was normal, started car next day and rpms shot high and light came on. They reset light and say nothing wrong but this keeps occuring. Highly upset as I have absolutely loved everything about this car until now.

At around 80,000 miles car started going down hill. It hesitates to take off from a stopping point. It shakes sometimes when about to accelerate and it doesn't accelerate very fast anymore gets up to about 1800-2000 RPM before it actually picks up speed.

My 2015 Sonata 2.0 sport engine stalled while I was waiting at a traffic light in the middle of rush hour traffic (oakland) pittsburgh, pa. Vehicle was tying up traffic so bad that a university police officer helped me push vehicle to side of road. Got vehicle towed to #1 cochran Hyundai monroeville, pa. Was informed vehicle engine seized up and a replacement would be needed. Been without vehicle since mid May 2018, while still paying car note, insurance and car registration! I need to be compensated!!! luckily, engine is covered under warranty but still a big inconvenience!!!! Hyundai how will you smooth this over with your customers"?"

Whenever I come to a complete stop while my vehicle is in drive, the RPM's idle at a dangerously low level that upon releasing the brakes in order to drive again, the vehicle sputters and struggles to take off. A couple of times the vehicle has actually stalled out while sitting at an intersection while trying to drive. The only way I have been able to find a fix to this problem is by keeping the air conditioning on which appears to make the vehicle RPM's run a little higher in turn not allowing the vehicle to get to dangerously low rpms. As far as I can tell there are no recalls out there pertaining to this while other individuals appear to be experiencing the same thing. Dealership states that it is normal. I purchased this vehicle about 2 months ago so I am not sure if this was a common occurrence with the prior owner. Seems like if Hyundai were to increase the rpms while it is in an idle state (in drive) then this would not happen.

I cranked the car in my driveway and it was shaking a little, which I thought was strange and when reversed and started to drive the check engine light came on and then the car died. It had 59156 miles on it at that time. Hyundai towed it to the dealer for me and they said they could not get any error codes or see anything that was wrong with it.. they said bring it back if there are more issues.Hyundai kept the car for more than a week to see what was wrong..

Our car was serviced by southwest Hyundai dealer in albuquerque on 7/6, and although it was idling rough, they told us our car was safe to continue our vacation to co. The next morning, 30 miles later on I 25 we were traveling the speed limit, and a clanking noise started and smoke poured out from under the hood...we pulled over immediately. Billows of smoke. We called 911 and road assistance. Santa Fe fire dept forced hood open and flooded the engine. Car was towed to sante fe Hyundai fiesta. Our insurance company inspected and said the car was totaled. Hyundai corporate will be inspecting the car to try and determine cause. According to geico adjuster, that may not be possible. Everything melted.

Vehicle was stationary when started up. The engine started the rattle while in idle. After letting the car sit for 10 minutes, proceeded to drive normally. The engine would then rattle during acceleration and applying more rpms. The rattle was directly related to applying more pressure to the gas pedal. This car has 12322 miles and the rattle started to occur at 12000 miles to the best of my knowledge. Vehicle was started in driveway and rattle was heard at intersection and then later on highway. I'm concerned this rattle will damage the engine but specific components are unknown.

With only 27,000 miles, the car stalled at an intersection without any warning on a June day in 2016 in Texas. Towed to dealership for warranty repair. Warranty company declined the repair, claiming "customer maintenance issue". warranty company refused repair after looking only at photographs of the engine. Warranty company didn't request, and dealership refused to even accept owners maintenance records. After the repair was declined, I researched the problem and found out about recall for previous model years 2011-2014. That recall was a response to similar failures and customer's similar complaints about warranty company automatically claiming "customer maintenance issue". dealership shared with me their communications with the warranty company which asked only for photos of the problem. How can the cause of the failure be determined by photographs of the engine when the previous four model years used the same exact engine model resulting in major recalls" also, how can the warranty company refuse to see maintenance records and then blame owner's for the failure? clearly the company is executing a nationwide policy of declining repairs even when they are covered by the warranty. How many similar failures were covered by the warranty"

Air intake was replaced 3X. 3rd time lead to turbo failure. Thompson Hyundai replaces turbo but doesn't put antifreeze, tighten oil screw (which blew oil all over engine), and they didn't even test drive it. Drove vehicle, smoke starts pouring from the vents, engine overheats. Vehicle gets towed back to dealership. Currently vehicle has check engine light on, rough idle and doesn't accelerate. Almost got into an accident because loss of acceleration. Also, the sunroof winddeflector which was recalled is now coming off again. Dealership used a small amount of glue to adhesive it back to the car. The glue has failed.Hyundai needs better service techs. They have destroyed my car.

I sought service for loud lifter noise at 50,000 miles, but was told the noise was from an after market (jiffy lube (fram filter)). The service dept. Frank Hyundai, chula vista, ca drained my new oil, and did a complete new oil and filter change. The lifter noise continued. At approx. 122,000 the engine began to knock while on the freeway - mason auto, imperial beach, ca did a complete engine diagnostic and determined the noise as engine knock. From lifter noise to engine knock. I cannot drive the car for fear of complete engine failure! mason auto of imperial beach, ca informed me that this was the fourth Hyundai they had diagnosed with engine knock recently.
