2016 Hyundai Elantra problems

“Vehicle stalls while driving which is very dangerous. All dashboard lights go on prior to stalling. No engine light is on. Knocking sound coming from engine. Dealer states engine needs to be replaced. Car has been serviced regularly despite that Hyundai denies engine replacement. The knocking sound that engine does is common between this model and year but mysteriously there has not been engine recalls.”

“Transmission P0731 code. Vehicle will not shift into 1st gear when idle but will stay in 3 or 4 gear. Speedometer would indicate high speed when pressing on accelerator. At traffic light when light turn green car rev but would not shift into gear. Has only 130K miles. Car was towed to dealer and required a new transmission.”

“The contact owns a 2016 Hyundai Elantra. The contact stated that while operating the vehicle, the air bag warning light remained illuminated. The vehicle was taken to the local mechanic, who informed the contact of a Manufacturer's Extended Warranty Coverage for the failure and referred the contact to the local dealer for assistance. The cause of the failure was not yet determined. The contact was informed that the vehicle was not covered under the extended warranty. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 53,600.”

“The vehicle's security system malfunctioned immediately after service at Parks Hyundai of Gainesville on 05/27/26 for Recall 256 & Campaign P33. The alarm blares & emergency lights flash while I am driving on public roads. This defect first presented in the dealership parking lot upon pickup. This creates a severe safety risk: the high-decibel alarm is a major distraction, the flashing lights confuse other motorists, & the malfunction prevents me from using turn signals, violating safety protocols. I demonstrated this to the service manager on 06/10/26. While the technician acknowledged the defect during a road test & performed a 'cap reset' (documented on the repair order), this attempt failed to resolve the issue. Despite this, the service manager refuses to acknowledge the defect, claiming it is an 'intended feature' of a 2023 recall at a different facility (993). This contradicts the technician's findings & my years of incident-free driving until the work on 05/27/26. The dealership initially omitted my return visit from their records, only acknowledging it after I confronted them in writing. An independent shop confirmed this electrical failure likely…”

“I received confirmation from my local Hyundai dealership that my 2016 Hyundai Elantra GT is consuming over 1.8 quarts of oil every 1000 miles. The mileage is currently 70k miles. This is not the result of lack of maintenance or neglect but because of Hyundais engine design. I was told by the local dealership that I would need a total engine re build. This was the only option to fix the issue 100%. I was told that if the issue is not fixed it will result in engine failure. Hyundai is not recalling their engines or acknowledging the inherent danger this will cause. I am at my engines will if I cannot afford this repair because Hyundai won’t honor the Powertrain warranty.”

“I was driving normally down the road and all of a sudden I lost control and couldn’t turn my vehicle apparently the control arm rusted from the subframe, causing me to swerve hit a curb and cause more damage to the front end. Thank God I was on a not so busy street! I could have killed myself or someone else all because this company’s metal rusted out.”
