[xxx] [xxx] [xxx]; [xxx] [xxx] [xxx] date: xxx national highway traffic safety administration office of defects investigation (odi) subject: formal safety defect complaint – 2017 Hyundai Sonata theta ii engine failure, excessive oil consumption, intake/engine component failure and safety hazard dear sir or madam: I am submitting this formal complaint and request for immediate investigation into the dangerous and ongoing mechanical failures involving my 2017 Hyundai Sonata equipped with the theta ii engine. I believe this vehicle contains a serious manufacturing and/or engineering defect that presents a substantial safety hazard to consumers. My vehicle has experienced a pattern of progressive mechanical failure beginning with abnormal and excessive oil consumption, which appears to be directly associated with malfunctioning engine airflow and intake-related components. Specifically, the lower engine airflow system and intake functionality appear defective, placing excessive strain on the intake manifold system and contributing to cascading engine failures. As a result of these failures, the vehicle has experienced: severe and excessive oil burning/consumption intake manifold malfunction and abnormal operating stress suspected overheating and/or premature head gasket failure ignition coil failure and electrical shorting/misfires progressive engine deterioration rendering the vehicle unsafe and unreliable increased risk of sudden engine shutdown, stalling, fire hazard, or catastrophic engine failure while operating the vehicle has become increasingly unreliable and inoperable due to these conditions. These failures raise significant concerns regarding public safety, especially given the known history of complaints and recalls associated with Hyundai theta ii engine defects. I am deeply concerned that this vehicle may reflect a broader pattern of defective manufacturing, insufficient quality control. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
To whom it may concern, I have own my vehicle since Jan 2018, which was purchased from the dealership's owner w/less than 10k miles. Maintenance has been performed iaw Hyundai's recommended schedule. However, yesterday, I was informed that my vehicle needed a new engine and other replacements totaling $13,934. 89. This is outrageous. How can a well kept vehicle w/106445 miles, need such replacements? thus your assistance will be greatly appreciated.
The engine light keeps going on and off and I reported to their dealer a couple times during the warranty but when they checked the car the light got off and they asked me to keep driving it until out of warranty and they ask me to pay for fix the same problem.
I was stopped at a red light. Once light turned green I went to make a left-hand turn. My vehicles power steering shorted out, almost causing me to hit a pedestrian and child.
