2016 HYUNDAI ELANTRA Complaints

The motor started to make a ticking noise 5 months earlier. 5 months later at 180,000 miles a borascope finding, reveled all 4 cylinder walls were worn related to cylinder slap. Called Hyundai dealership and was told ithe car is too old and the milage too high for a warranty coverage.

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.

P0420 P0441 P0014 P1326 C1260 C1688 C2130 These are the codes that's affecting my car

Engine burned oil and had knocking sound, despite having regular oil changes. Stalked out while driving took to dealer initial said it was covered by the exerted coverage but ultimately denied. It had 111,000 miles on it. I believe this engine has the same issues as the others.

The oil light & check engine started flashing. Took it to the auto shop. The mechanic stated that the oil level is very low and the engine has a bad lower-end knock. Removed the oil filter and found metal debris in the oil. No oil leaks were found under the vehicle at all. Oil is being burned out through the exhaust. The vehicle needs an the ngine replacement.

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.

2016 Hyundai Elantra (75k miles) experiences severe, un-commanded Loss of Propulsive Power and a Severe Drivetrain Instability Hazard. At steady highway speeds, the automatic transmission completely loses hydraulic pressure, slips out of gear, and unexpectedly drops into a temporary "neutral." The engine suddenly revs up to high RPM on its own while losing all forward acceleration. After coasting helplessly, it violently slams back into gear, causing the vehicle to lurch forward. This also happens from a complete stop.The vehicle's OBD-II system fails to illuminate the Check Engine Light or store fault codes during these flares, providing zero warning before a loss of propulsion.This dangerous transmission slipping has occurred intermittently for several years. I repeatedly took it to an authorized Hyundai dealership to address this crash hazard. Because there was no active Check Engine Light, the dealership dismissed my concerns, refused to document it, and sent me away without a diagnosis. Recently, the service department acted in bad faith by misrepresenting my warranty terms (falsely claiming it was only 7 years) and refusing a live-data diagnostic scan. The bad faith dealership was Murdock Hyundai of Murray in [XXX], specifically the service manager Tyler as well as Krateton. The car is a verified vehicle under the Hyundai Nu 1.8L Piston Slap Class Action Settlement (TXXK Campaign). An official safety escalation case is open with Hyundai Motor America under my corporate case number XXX. I request a federal safety investigation into premature transmission pressure failure in 2016 Elantras, as this vehicle is entirely unsafe to operate.

My driver side window has not been working for almost 3 years now. I have taken it to 4 mechanics and they fix it but only last a couple days. They have all say they can’t really do anything about it since they need an original piece. My AC is another issue I have that I have tried fixing 3 times now. The same issue happens they fix it and it last about a week or so. The longest it has lasted was 2 weeks. The mechanics each say it needs a new compressor and I’ve bought 3 new compressor already. I’m not sure what to do anymore.

The car turns off while driving it without warning or anything. Place where I got it don’t want to fix it

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 stems from P33, but requires proprietary dealer tools to diagnose. Attached video proves the vehicle runs while the alarm blares, confirming no relation to old Campaign 993 logic. Attached Repair Order proves the technician acknowledged the defect & attempted a repair. Despite this, the service manager ignores the documentation, his own technician's findings, & my demonstrations, blaming my locking habits while refusing a deep diagnostic. After 16 days in their possession, neither the dealer nor manufacturer has provided a remedy. If this malfunction were an intended feature, it would be an ongoing hazard; it creates a distraction, causes a panic response, & prevents the adequate use of turn signals while in operation. The vehicle is unsafe, & the dealership & manufacturer have failed to provide a valid repair.
