2016 Hyundai Elantra Powertrain & Transmission Problems

Vehicle started to violently lurch when shifted into drive. A week later loud clunking sound also started when shifting into drive. Sometimes would not go into drive and had to use manual 1st, 2nd, etc. Reverse was fine, no issues. No dash lights ever came on. Auto parts store had error code P0722. Have a diagnostic appt in a week at local Hyundai dealer. We may attempt to replace input/output speed sensor to solve, but probably will let dealership do diag first. Mileage approx 84686. Very dangerous at stop lights if can not get car into drive. Crash risk is high.

The contact owns a 2016 Hyundai Elantra. The contact stated that while driving at 45 MPH, the vehicle jerked with an abnormal sound coming from the transmission while shifting gears. In addition, the vehicle failed to accelerate as intended while depressing the accelerator pedal, and the vehicle stalled. No warning lights were illuminated. The contact was able to coast to the side of the road. The vehicle was towed to the dealer, where it was diagnosed with transmission failure due to a workmanship error. The contact was informed that the transmission needed to be replaced. The vehicle remained at the dealer unrepaired due to the cost. The dealer notified the manufacturer of the failure and submitted a request for a new transmission. The manufacturer declined the request. The contact notified the manufacturer and was informed that there was no Extended Warranty on the vehicle declined to offer any assistance. The failure mileage was approximately 93,000.

While driving on the freeway at normal highway speed, the vehicle experienced a sudden and catastrophic engine failure. The engine immediately lost power, and the vehicle shut down within seconds. There was no prior warning or opportunity to take corrective action. The vehicle became completely disabled and could not be driven. This occurred late at night with limited traffic, and I was LUCKY to be near a freeway exit. I was able to coast toward the exit, but the engine seized fully, resulting in total loss of propulsion and blocking the freeway exit ramp. Law enforcement had to assist due to the disabled vehicle creating a traffic obstruction and safety hazard. A tow truck was required to remove the vehicle because it could not be restarted or moved. Under normal traffic conditions, this sudden loss of engine power at freeway speed could have resulted in a SERIOUS, potentially FATAL COLLISION. The outcome depended on luck, timing, and location rather than any safety system functioning as intended. The engine was later diagnosed by an authorized Hyundai dealership as seized due to internal failure. Hyundai denied warranty coverage because a software safety campaign had not been completed prior to the failure, even though the failure occurred suddenly and without warning, leaving no opportunity to complete the campaign. However, at the time of the failure, the NHTSA recall lookup tool showed ZERO unrepaired recalls associated with this vehicle’s VIN. The campaign referenced by Hyundai is intended only to detect certain engine conditions and does not repair engine defects. In this case, the engine failed before any detection or warning could occur. The vehicle had just been refueled and was equipped with four brand-new tires, confirming it was being operated normally. This incident involved an unexpected and complete loss of engine power at freeway speed due to an apparent engine defect, presenting a SERIOUS SAFETY RISK to the driver and other motorists.

Engine turns off unexpectedly when driving. all power steering and brakes stop working when engine itself off. entire engine, drive train, and vehicle shakes while driving. Transmission is a replacement as first one failed after 90 days of purchase. paid labor for replacement and waited over 6 weeks without a vehicle. Now replaced oem transmission slips out of gear. making vehicle difficult to drive as the transmission and engine sputter and make ride jerky. car has turned off on the freeway in traffic 3 times. almost causing an accident each time. car has been robbed at least 5 separate times. stealing items within the vehicle. car was locked and next day it is unlocked and my stuff all gone. i am scared to drive the vehicle. i believe it is a lemon.

Bought a 2016 Elantra in 2020 with 44,000 miles on it and a clean repair/ maintenance history. Let me preface the rest of this by saying I am an ASE certified mechanic of 15 years who has been in the industry even longer. The first major issues I incurred with the vehicle happened approximately one year after purchase. The lifters started tapping and not long afterwards (about a week) I had a total engine failure on my hands. I was almost killed by a passing semi truck that was merging on to the interstate but was luckily able to avoid it and get the car on the side of the interstate where I had it towed to Ralph Sellers Hyundai in Baton Rouge Louisiana. Long story short , even though the second owner is entitled to a 5 year, 60,000 mile warranty, they made me pay for a new engine. Here we are only 19,000 miles later and the same issue is occurring; except this time due to the stress the failing engine is putting on the torque converter the transmission is now failing to do its job properly. I have been back to the dealership but they offered no help except lies (they told me my high pressure fuel pump was bad, this model doesn't even have one!!!!!) I fully intend to sue Hyundai of America unless some appeasement can be made. Do not EVER buy a hyundai, they are trash cars made to look nicer than they are. Additional details will reflect most recent incident with engine/transmission.

I own a 2016 Elantra with around 140,000 miles and the car just stopped going forward the car only goes in reverse, no warning light came on, no other issues or warnings that there was something wrong with the car.

The transmission continues to stall. Very dangerous….as I was pulling into a gas station and the car stalled. When placed into gear the vehicle would not drive forward and began to roll backwards. The vehicle is available for inspection. Due to the sudden stall a serious accident could have occurred. I took the vehicle to a mechanic and he confirmed that all fluid levels were good but the vehicle is in need of a completely new transmission. The current transmission can’t be repaired. The vehicle showed no warning signs or lights prior to incident. Can’t drive the vehicle as it is not safe. The vehicle is parked in a garage to avoid accident. The vehicle was driven low mileage over the last year.

INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Initial report on March 7, 2022 (approx. 94K miles), second report on Dec. 12, 2023 (approx. 111,700 miles). Third report March 27, 2024: Recent event occurred on March 23, 2024 (approx. 112K miles) when my vehicle suddenly stopped moving while driving 55mph on a freeway with child passenger in the vehicle, putting both of us at risk for collision. Vehicle did not have any warning lights turn on prior to or during event. The vehicle did not move again after multiple attempts to accelerate to exit freeway safely. After shifting to neutral and back to drive, the vehicle suddenly jolted and accelerated randomly while holding foot on the gas pedal (no control over timing of acceleration). We were able to exit the freeway safely. This same issue repeated multiple times while driving us to a safe area to call for a tow truck. The vehicle was towed to dealership location it was originally purchased at on March 26, 2024. Diagnostics appointment scheduled for March 28, 2024. I have completed oil change services on this car about every 1,200 miles to keep the engine running since there was no solution for any of my previous reports to dealership (even when opening a case with Hyundai), their previous determination was to close case since the diagnostics report did not show error codes in report. Previous dealership advisor made a verbal comment that the real problem is something their computers do not scan codes for, and his recommendation was to "drive it til the wheels fall off" after paying thousands in services that did not solve the root problem. Hoping this appointment will lead to a safer outcome.

Bought the car a yr ago and transmission started slipping and stalling sometimes even engine shutting off while driving at higher speeds unable to steer and when pulling into traffic is on interstate almost got hit because I could not speed up it's also using double the fuel while driving longer distances I tried to use my warranty 2x before my warranty was up but both neither time did Hyundai in Owensboro check what I booked the appt for. First one was booked to check transmission and power issue then called the day before and added oil change. When I arrived the tech retyped my order and changed the oil. Brought my keys I asked about the power/transmission issues and was told they didn't know to check that but at that point there was no time and had to reschedule... So I did. Waited almost 2 months booked appt for transmission / power issue and also check the fuel usage. Finish the service call quoting me over $1300 to fix the fuel issue because no one could find my warranty eventhough I had my original paperwork showing who warranty was with and also the acct number for the warranty. When I asked about transmission or power issue I was told there was no one to check that and I had to rebook but this time it was going to be 8 weeks and by then my warranty had expired. I feel like Hyundai did this on purpose because they are in cahoots with the lot I bought the car from. Now my car is getting worse and worse and scared to even drive the car im overpaying for. This was my first Hyundai and more than likely will forever be my last because the car I got was a lemon it seems, the customer service was worthless and the service even worse. I'm reporting to BBB and everywhere I can.

My Hyundai Elantra started completely shutting off while I was driving. This happened on multiple occasions like in slow traffic and while going high speeds on the highway. This is scary and dangerous when my toddler child is in the car. I took it to 3 different mechanics and no one can find any codes or anything wrong with it---but it continues to happen and put my life and my daughters life at risk. I have seen so many people complaining of the same thing--but nothing has happened? This last dealership has had my car for 3 weeks (and counting) but still cannot find the issue. I have about 125,000 miles on the car.

Car stutters at low speed.

I believe it is the transmission/ power train that failed. It slides gears and the engine stalls. While driving, I was almost hit because I could not speed up. I had to decelerate in order for the gear to not stutter.

On 06/10/2022 Going down the road went to shift gears and it was stuck in 5th gear. Finally got it released and safely made it home. Ever since you can shift the gears and reverse while engine isn’t running but once I turn on the vehicle it refuses to shift into any gears including reverse. I have a FIXD OBD2 sensor and it showed no warning messages before, during, and now. No codes are showing up when plugged in. Matter of fact it says there’s no issues with my car ? I had a mechanic take a look since he was willing to come to my house considering I currently don’t have the funds to get it checked out & he said it’s probably my clutch has went out, but that can’t be the case considering it will turn on still. I have no messages appear on the dash & I have plenty of transmission oil. Today is 07/08/2022 and it has just been sitting there due to the fact I’ve lost my employment and can’t afford to have it looked at

April 2022 Car engine stalls while at stop sign or light. Started happening once or twice every few weeks. Took the vehicle to two repair shops but could not diagnose the issue. Vehicle giving no diagnostic codes or warning lights. May 2022 vehicle is now stalling and losing acceleration while driving on busy highway, leaving me and my children on the highway shoulder. Car loses acceleration and coasts to a complete stop. No warning lights have come on previously. Could not book an appointment with Hyundai dealer until June 25, 2022. As of June 3rd 2022, check engine light is on and car having trouble starting back up after stall. Vehicle is stalling and losing acceleration 2-3 times a day no matter the speed. Booked appointment with Hyundai dealer in another area for June 9, 2022.

My 2016 Hyundai Elantra started jerking and losing acceleration power. I got stuck at a stop sign because the car lost the ability to change gears. It felt very unsafe to be stuck in the middle of traffic and have to wave people around my vehicle at night. I’ve taken it to two different mechanics who have both said my vehicle has experienced premature transmission failure due to a factory defect. The car has 90,000 miles. I am a second owner so my warranty ended at 60,000 miles. There was no warning or dash lights. It was very abrupt and unexpected.

Check engine light didn't come on until the car no longer went into gear. Prior to light coming on car started jumping like 3 feet when going from park to drive sometimes and would do the same sometimes after proceeding from a stop. After about 2 weeks of doing this car would only go in reverse then the check engine light came on. Had it towed to dealer to be serviced. They said i need a new transmission and cost over $6800. Car has been in shop for 3 weeks now. I filed a complaint with you guys and was told to see if Hyundai would make things right and make it a recall since it was a huge safety issue i think. However they said there was nothing they could do cause my warranty was up cause I'm almost to 130000 miles. That shouldn't even matter it was still a safety issue. I was reading and found that a lot of people were having similar issues and Hyundai does nothing about it.

My vehicle is only 5 years old and the transmission has problems. I was driving and the car stopped with an impact force. I thought that someone or something had hit me from behind. For over over 2 months, I have been without a vehicle because the mechanic shop states that the transmission need part replacements.

My vehicle started to have a slight delay when shifted from park to drive. Within a week's time the delay turned to a very hard shift which made car jump fast and hard making tires screech yet there was no check engine light. Then it started slipping out of gear on highway then it wouldn't go into the last gear and when in stop and go traffic fall out of gear when stopped then thrust really hard burning rubber when accelerating so had to distance myself far behind other cars so I wouldn't crash into them trying to accelerate after a stop. I get home safely let my vehicle rest a few hours before attempting to take car to be inspected. So I back out of drive way and my car doesn't go into drive at all and then the check engine light comes on. Now I have a friend bring scanner and the code P0722 comes up. I am disabled and on a fixed income still paying on the car. Luckily I broke down in front of my house.
