Engine Failure problems of the 2011 Hyundai Elantra

There was total engine failure when the car reached about 80k miles. This is known for in the 2011 Hyundai Elantras but hyundia has yet to recall the Elantras just the sonatas. Despite constant and frequent oil changes oil sludge formed and entered the engine compartment completely rendering it unrepairable. A "new" engine had to be placed but I was warned the problem could occur again but a recall still has not been issued. This is dangerous as the engine was sputting out, misfiring and blue smoke was being released from the exhaust due to this.

I started my car and it had developed a loud knock. My car has just over 82k miles. My mechanic informed me that it needed a new engine. I took my car to two dealerships and both said it was a common problem/defect for this make and model year. The dealership informed me that it was caused by a coating on the pistons coming off that eventually causes the knock and engine failure. One dealership had 3 Elantras in their shop for the same issue. My car is not under warranty as I am the second owner. This defect should be addressed as it is exactly the same issue as the sonatas which were recalled.

Bought this car used in 2014 with approx 24,000 miles. Ran great first 2 years but at approx 39,000 miles a very loud engine knock developed and has effected the engine performance. This issue is present at start up, idle, in motion, each time the car is running. Hyundai service mysteriously could not hear or diagnose the problem. Engine knock has continued get worse and power has diminished. The engine has not yet failed but most certainly will very soon. My family is at risk each and every time we use this car. The engine problems are similar to the sonata's and santa fe's as well as the kia optima models from 2011 thru 2014 which were part of a class action lawsuit after which there was a engine recall. My understanding is that Hyundai has extended warranty to used Elantra models to 5 years and 60,000 miles. At this point we have only 56,000 miles but the car is 7 years old. They have a known manufacturing problem and are not owning it for all affected and that's catastrophic for those of us not covered. Dealer has told me if I have engine failure the cost of a new engine will be near $5000. Hyundai makes attractive cars but their lack of compassion to the victims of their poor manufacturing process makes Hyundai a poor choice. There have been class action suits for the sonata and optima but no judgement for the benefit of Elantra motors who's engines suffer the exact same issues. There was a whistle blower who opened this all up and said the judgement was not far reaching enough to cover all victims. . Read more...
