I am reporting two unresolved safety concerns despite repeated repairs and more than five months of seeking assistance from Hyundai. Multiple ignition coils have failed during my ownership. Most recently, I paid approximately $400 for service after another coil failure. Although the check engine light is no longer illuminated, the vehicle…

   I bought my 2017 Hyundai Elantra SE earlier this year with about 119,000 miles. It had good maintenance records when I bought it, and it now has about 128,000 miles. Since buying it, I've had two oil changes done along with new spark plugs, coils, front brake pads, and tires. About two days before the engine failed, I noticed the car had suddenly burned through a significant amount of oil. There was no visible oil leak. The car stopped running, so I had it towed instead of…

Once again, it would start up again but stall every few feet. We took it to another Hyundai dealership. They…

   1. The engine architecture suffered a catastrophic mechanical failure. Specifically, severe, systemic internal oil consumption/vaporization starved the hydraulic timing chain tensioner of critical hydrostatic pressure. This caused the tensioner to collapse, creating slack in the steel timing chain, which then "jumped time" (skipped a tooth on the camshaft sprockets), causing the engine to instantly seize and lose all motive power. The vehicle and engine are fully intact and…

   I own a Hyundai Elantra with approximately 103,000 miles. The vehicle has developed an intermittent issue where the engine will suddenly stall while driving.

At the time of the stall, multiple warning indicators appear simultaneously, including the check engine light, battery warning light, and a “no key detected” message. There are no prior warning signs before the…

    Car was constantly losing power, called Hyundai dealer about the OBI system thinking that could be the cause they told me no, and then in 2 years ago the car started stalling when you slowed down and on the way home from work it completely died. Car still turns over but car will not go, engine and transmission are completely done. It’s been at my house sitting since. Hyundai dealer is a joke a wouldn’t help when the issue first arised.
