2012 Hyundai Sonata: shudder or vibration when accelerating

Filed Mar 31, 2024 · Engine, Fuel system · NV

Approx one year post engine replacement, and 2 weeks prior turbo system replacement, I am having major issues with my sonatait struggles to stay started, it always hesitates and doesn't want to move when I press accelerator, shakes jolts and shudders, the smell of burning oil comes thru the vents and even smoke comes out from under the vehicle. The engine is leaking masses amounts of oil that seem to be leaking from all over the under carriage and half way to the back underneath the car, oil is in the wheel wells, and even splashed on the rims, the spark plugs are covered in oil, huge plums of white and dark smoke come out of the tailpipes, literally blinding anyone behind me, press the accelerator to the floor and it just shudders and smokes even more, check engine light is on and states malfunctioning turbo system, boost pressure sensor malfunction, sluggish will not gain speed, oil within the turbo blow by hose and in intake hose area, now I have coolant pouring out and the reservoir the coolant will be literally boiling. This is not good at all especially after a year post engine replacement and turbo replacement. When the car is started I push start and car struggles to start the starter keeps screeching and car shudders for a good 45 seconds before it either dies out or finally starts. This vehicle should be a lemon and bought back regardless of age condition etc. A vehicle after engine replacement of only one year should not be pouring oil out of the engine, failed head gaskets,misfiring and leaking coolant. I keep receiving recall notice after recall notice in the mail stating I have recalls that need to be addressed but when checking using my vin it says there are no recalls needing fixing, that makes me uneasy and I don't feel safe driving the vehicle I lost faith in it all together

Above approximately 60 MPH steering column develops a shudder which builds and wanes - steering becomes more challenging as a result. The greater the speed, the more pronounced is this condition. This is a suboptimal condition that is not typical for a functional vehicle, and is unrelated to wheel quality, rotation or balance. It is a temblor-like shudder which clearly will interfere with safety if it continues or progresses. Perhaps this is related to the federal safety agency id number: 10110926, but this vehicle is now at 108k miles, so that doesn't cover it, does it. Further, I have no record of notification of receiving manufacturer communication number: 5np-f8m5g-03. I will be contacting the dealership contending inadequate notice, and needing this to be repaired to assure safety.

The problem started when my steering wheel began to rattle a week ago causing a harsh shake at the hands and a loud noise in the steering column. I called the dealership and they informed me it's a defective bushing that malfunctions and a large majority of sonatas are having this issue. He said it's happening so much that the manufacturer can't keep up with producing the part so there is a slight delay on fixing it. I asked if the vehicle is safe to drive and he informed me the manufacturer said it's safe. I scheduled an appointment for a week and a half out, due to the supply and demand of the part. During this period I continued to drive the car and it would occur every time the car was in motion. While driving to work on a highway the steering deteriorated so quickly not only did the steering wheel start to shake violently but the entire vehicle would completely shudder while driving it. It felt like I was driving on an ungraded dirt road and the rattle was increasing loud out of the steering column. The vehicle became extremely unsafe and hard to handle as the steering would sway. This made the vehicle loose and uncontrollable to drive. There was no safe options to continue to drive the vehicle until it was fixed. There are very few vehicle issues more dangerous and devastating than loss of steering while driving a vehicle. This is roughly a $5 dollar bushing that takes around 2 hours to fix. A defect that is this simple to fix but is extremely deadly gives plenty of cause for a recall. On top of that, there is no doubt that a recall is necessary because of the widespread occurrences. Hopefully this doesn't continue to unannounced until major accidents happen before they fix this major defect. Please refer to the safety recall compendium where this fits the criteria for the federal safety agency. Http://www-odi.the federal safety agency.dot.gov/recalls/documents/recompendium.pdf
