THE AEB SYSTEM DOES NOT SHOW ANY WARNINGS OR ATTEMPT TO STOP THE CAR. I DO NOT DRIVE AROUND TRYING TO MAKE THIS FEATURE WORK BUT AFTER GETTING THE NEW CAR I DID REALIZE IT WAS NOT DETECTING ANYTHING WHILE MY OTHER CAR DETECTS AND STOPS FINE IN THE SAME SCENARIO. I HAVE GONE TO THE HYUNDAI SERVICE CENTER WHERE I PURCHASED THE CAR ABOUT THIS AS WELL AS SUBMITTED A CASE WITH HYUNDAI CORPORATE. CORPORATE RESPONSE WAS: GO BACK TO THE SERVICE CENTER AGAIN AND TELL THEM WHAT MY CONCERN IS (AGAIN). SO, I DID. HYUNDAI SAYS THEY WILL NOT TEST THE ISSUE AND SINCE THE COMPUTER SAYS THERE IS NO ISSUE... THERE IS NO PROBLEM WITH THE FEATURE. I HAVE MADE A VIDEO OF THIS ISSUE AND POSTED TO HYUNDAI FACEBOOK AND GOT NO RESPONSE. I AM CONCERNED AS WELL AS FRUSTRATED WITH THE LACK OF ATTENTION FROM HYUNDAI FOR THIS SAFETY FEATURE ON MY CAR. I HAVE READ THE MANUAL, CONFIRMED THE SETTINGS AND REQUIREMENTS FOR THIS FEATURE TO WORK AND IT SIMPLY DOES NOT WORK ON MY CAR AND FOR HYUNDAI TO TELL ME THEY WILL NOT TEST IT AND THERE IS NO PROBLEM BECAUSE THE COMPUTER SAYS THEIR IS NO PROBLEM IS SAD.

On Thursday evening, 4/28/22, I noticed engine knocking, and engine died while driving. Checked oil, and there was no oil in the car. Added oil, drove car to work the following day. Still engine noise, and dying on freeway. I never had any "check engine" or "low oil" warning lights come on to aleart me of any issue. The car only has 57K miles on it. Took the car straight to the dealership, and they are saying I need a new engine since they found metalic pieces in the oil. I know therer are other Hyundai recalls and lawsuits for engine problems, but not for this year/model. Service center said they are filing the warranty paperwork with the AutoNation Gold Extended Warranty, and I should expect a call today 5/5/22 to find out the status. Not sure why they are not using the Hyundai Powertrain warranty. (2nd owner, should be 60K milkes)

5/5/2022

We were driving the car and all of a sudden it would only go 30 mph and starting making a noise, pulled over and car would not go anymore. I took to a shop authorized from my carmax care program and it was diagnosed as rod bearings broken in the engine. This is a know issue with this model and Hyundia extended the warranty due to know issue. We were then advised to take to a dealer since a warranty issue, when it got there and they looked at it and the repair shop called them to tell them they broke it down to failure the dealer is now trying to charge me 8 hrs labor to look at. This is not a my issue , its a manufacture issue so I should not have to pay all this money to have same diagnostic I reported to Hyuandi headquarters and also reported the shop. Someone needs to fix this issue my case # with Hyundai is 20400619

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

Previewing the first 2 complaint summaries.

Parked car on street (facing slightly uphill) on Saturday morning, neutral weather conditions. Upon starting car several hours later, yellow warning lights were displayed for Collision Avoidance, ABS, and Stability Control. Yellow Auto Hold light was illuminated and could not be shut off. Message panel indicated that AEB system needed to be checked. Carefully operated car to attend scheduled event, seemed to operate normally on surface roads. Unable to obtain service on weekend. Ran car through car wash, made ~150 mile return trip home, found that cruise control not operational due to problem(s) with required systems. Did not attempt to disable adaptive cruise function and operate basic cruise control. OBD codes obtained upon return home were: C136 081 (History - ESP Irreversible error) C174 181 (History - ESC Vehicle safety management (VSM) unavailable (Check ESC)) C120 881 (History - Left rear vehicle speed sensor (VSS) invalid/ no signal) C120 702 (Active - Left rear vehicle speed sensor (VSS) range/ performance/ intermittent) C120 802 (History - Left rear vehicle speed sensor (VSS) invalid/ no signal) I cleared the codes, put vehicle in gear to move forward and back in driveway without immediate recurrence. Adding information here in case this happens again or affects other drivers, vehicles. No history of prior mechanical problems, no accidents. Speeds were variable, from 25 mph on surface roads to 70 mph on trip home.

8/7/2024

On 6/27/24 while starting my car in the morning an ABS failure light came on, various other system failure lights came on and have stayed on since that day including Cruise Control and Auto Hold. My car only had 33,250 miles on it! I purchased for an OBDII Reader hoping the failure was just a Wheel Speed Sensor. Unfortunately, the error code registered in the ECU was C240201 “Motor Failure” I brought in my car to a very reputable Auto repair shop, and for a $139 diagnosis fee, they confirmed that the ABS Motor / Pump had failed. The owner of the Repair Shop HAD NEVER seen a car of this age and such low milage have this failure previously. The estimate for repairs was over $2,000 as Hyundai is asking for $1300 + tax for just the part. I have read from on-line forums other Elantra GT 2018-2020 owners having the same failure and thought it should be reported.

CAR SHUT OFF WHILE ON THE HIGHWAY RANDOMLY STARTED SHAKING. ALL LIGHTS TURNED ON CHECK ENGINE,MOTOR OIL LIGHT BATTERY LIGHT. CAR SHUT OFF TO THE POINT WHERE I COULDN'T ACCELERATE. SO IMAGINE BEING ON THE HIGHWAY AND YOUR CAR SHUTS OFF RANDOMLY WHILE YOUR IN MOTION AND CANT ACCELERATE TO MERGE TO THE EMERGENCY LANE. THIS HAPPENED 4 MORE TIMES ON MY WAY TO THE DEALERSHIP LESS THEN 800 MILES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

9/20/2018

Engine, power train, malfunction changing my speed control. No warning lights, first ticking noise from engine then knocking loud noise from engine. Noticed ticking about 4 days ago at first, today on freeway going 60-70 mph just changed to loud knocking, immediately engine warning starts to flash on dash board then speed just drops from 60-70 mph to 35 mph almost got hit by trucker and another car . Under 90 day warranty still from dealership (27 days since purchased) no license plate yet but insured and registered. Read many complaints of the same problems from numerous of people having the exact same problem. Very dangerous when vehicle stops accelerating on a steep pass on hwy with heavy traffic, this was almost an accident report to dispatch but luckily I reacted fast enough to swerve to the side before hitting the vehicle behind me and missing 18 wheeler trying to get to the right shoulder because theirs no space on left just concrete dividers! To close for comfort I can imagine what really can happen to someone that can't react as quickly as I did. Feeling like a victim their is no way they were not aware of this problem that has happened to many others when it is coming from a Chrysler dealership after reading so many complaints and reviews. I wish I would of known before hand ✋️ I would of not even bothered but now this is what I'm dealing with instead of feeling safe and comfortable being in a reliable, gas efficient vehicle that I just purchased for $30,000 and my jeep as a down payment not happy with dealership nor product. Who do I look to, when insurance or dealership can't protect me from situations like this it's not fair to someone that's struggling day by day paycheck to paycheck and this happens and now on waiting list until December so dealership is able to take a look at it. This should be most definitely brought to attention!!!

TIRES:SIDEWALL

2 Reports3% of total

Previewing the first 2 complaint summaries.

The tires came stock on this model car and at the 30K mile mark I noticed cracking or splitting in the sidewalls of each of the tires. I am not aware if the manufacture, Hankook, has released any statements or confirmation about this issue but the issue occurred well with the 50K mile warranty window. This was shocking to see and could have been very dangerous to myself and other drivers had the cracking sidewalls on any of the tires failed or caused a blowout on the road. Because of the nature of this issue there were no warning signs. Luckily I caught this issue before it contributed to any accidents or harm.

10/1/2021

My vehicle is a 2018 Hyundai Elantra GT sport. The side walls on the Hankook Ventis S1 Noble 2 tires are cracking. The tires lose air constantly and cannot be driven on for a fear of a blowout. There has been a recall for this same make and model of tire just not this size for the same problem. This tire needs to be recalled before someone is hurt from a collision.

Oil drips on driveway. Warning sensors for blind spots disfunctional.

4/27/2022

The collision warning system has failed 4 or 5 times since I bought the car new in March of 2019. When the system stops working, the warning "Check BSD" appears on the driver's display. A couple of times the system started working without service. Other times service was required. The last time Hyundai service said the system went out of calibration. No explanation of how that would occur. They re-calibrated the system. Of course, once the system stops working, I have to remember that I won't get a warning when changing lanes or parking, so I must be sure to use extra careful. (I always look when I change lanes, but the warning system gives me extra confidence. I am sure many other people just rely on the system.)

MY CAR, WITH LESS THAN 4K, HAS A "SPONTANEOUS" WINDSHIELD CRACK THAT IS LARGE, LONG AND TRAVELS ACROSS MY LINE OF VISION WHICH IS A SAFETY ISSUE. NOTHING HIT THE WINDSHIELD, IT IS PARKED IS LOCKED GARAGE AND I DID NOT DRIVE OVER ROUGH TERRAIN, HIT A POTHOLE, DRIVE UNDER ANY BRIDGES OR PARK UNDER A TREE. I DIDN'T DRIVE ON A HIGHWAY EITHER. I JUST GOT IN MY CAR AND THERE IT WAS! THIS CRACK IS GROWING IN LENGTH AND I HAVE NOTICED SOME BLACK, FOAM TRIM CURLING UP ALONG THE EDGE OF WHERE THE WINDSHIELD MEETS THE HOOD. THERE IS NO VISIBLE POINT OF CONTACT THAT I CAN SEE, NO CHIPS, NO STAR BURST CHIP - JUST SMOOTH ON THE OUTSIDE AND INSIDE OF CAR. THERE IS ALSO SOME STRANGE SPLATTER MARKS ON THE INSIDE OF THE WINDOW AS IF A SMALL CARBONATED BEVERAGE WAS SHAKEN UP. OPENED & SPRAYED ON IT BUT THE SPOTS ARE HARD & CAN'T BE EASILY SCRAPED OFF. I WILL BE CONTACTING THE DEALERSHIP TO SEE IF THEY WILL REPLACE IT AS I DO BELIEVE THIS IS A MANUFACTURING DEFECT.

STEERING

Previewing the first 1 complaint summaries.

My 2018 ELANTRAGT was stolen due to Hundaes ineptitude and refusal to put in proper safety features. My car has been recovered but Hyundai does not have enough parts to supply this current crisis so my car will be in the shop for a minimum six weeks prior to being sent back to Hyundai dealership for the software upgrade that they are using as a fix. I don’t think this is enough on behalf of Hyundai. My car has lost resale value between 20 and 40%. I believe Hyundai needs to make proper compensation to me as a consumer. Additionally, my car was stolen in Oakland California at night and I. Stranded due to excessive call volume and had to go to downtown Oakland to one police plaza at night as a 60 year old widow with bad feet. I would like to see some support coming from your department as Hundaes position seems to be to make this a consumer issue that we are all financially responsible for.

Are complaints about the 2018 Hyundai Elantra GT a serious warning sign?

Potentially. 38 complaint reports fall into higher-attention systems such as brakes, steering, engine, powertrain, fuel, suspension, airbags, or electrical components.

How should buyers use complaint data for the 2018 Hyundai Elantra GT?

Use complaints as an early pattern to investigate, not a standalone verdict.
