| Description of the problem | 10/1/2014 @ 7:30pm est - while driving home, was at a red light when the car stalled out. Then a loud knocking sound happened. *no engine light was on* it is very unsafe for the engine to stall or just randomly shutoff while in traffic. There were no signs or warnings, the vehicle just stalled. Vehicle was not safe to operate. I had the vehicle towed to northtowne hyundai dealer on sheridan drive, buffalo ny. 10/3/2014 @ 2:47pm est - northtowne hyundai dealer called me said that i need to replace my engine because the piston popped. I said well, my car is well within the warranty, isn't this covered? Northtowne hyundai dealer said that we can't submit your warranty claim with out receipts of your maintenance from 5k miles to present. 10/3 - 10/13/2014 - contacted our 3 local places we like to send our vehicles to for copies of our receipts. With no problem we were able to obtain copies of our last 7 oil changes and general maintenance receipts. 10/14/2014 @ 2:00pm est - my husband gave northtowne hyundai dealer our receipts and he stated that he will submit our claim to hyundai. 10/24/2014 @ 8:59am est - "regional" / "corporate" called me and stated "the district manager who would have authorized the repair, had the dealership partially disassemble the engine; take off the cover for inspection, and there's a condition of sludge which is indicative of either the maintenance intervals not being followed; oil change not frequently enough or possibly the quality or grade of the oil used. In either case these is not a manufacture defect, so he has denied warranty coverage." i've also added my complaint to the following:[ http://www. Chimicles. Com/2011-hyundai-sonata-engine-failure-class-action-lawsuit ] ** our last oil change was 8/2/2014 at 43k miles ** we had a clean bill of health, no issues were reported or maintenance recommended at that time. |
