Engine engine undercover is not on the vehicle
I took my car in to have a recall repair completed. A relay kit was added to the engine compartment and my car has not operated the same since. When I start my car now it idles rough and is making noises that it wasn’t making before. When I accelerate my car stalls and is sluggish. Also when I accelerate my car stalls and speeds up uncontrollably, which is a concern for safety. I’ve contacted the dealership where this repair was completed and told them all the issues I’ve been having since the repair was completed. They keep stating that there is nothing wrong. I’ve spoken with Customer Relations and the Regional Manger only to get no assistance. I’m concerned about my safety and how this repair will affect my extended warranty because my engine has been altered. I wasn’t having any of these issues until this repair was completed and the dealership seems not to care or taking this seriously. The Regional Manager didn’t call me back until maybe a week or so after I kept constantly calling and advising that I was going to go to the news and get a lawyer. This issue has not been resolved.
At just 41,000 miles, the oil pressure sensor has failed. There are many on-line reports of this issue going back several years for the Genesis G80 sedan. It appears this is NOT covered under the 10 yr/100,000 mile warranty and is only covered by the 5 yr/60,000 mile warranty. In my case, this part failed almost 5 years to the day. It is unreasonable that the owner should get stuck with a $1000+ repair bill for a part that has a well known failure reported over and over. This should be a free repair.
Oil pressured sensor went bad $2500 fix from dealer. In Korea this is a recall. The Genesis forums are full of complaints regarding same issue. The factory should cover this but the 10 year 100000 mile warranty does not cover it since it is considered an electrical part.
