2012 Hyundai Sonata Hybrid problems

“1. It spun a main rod bearing. It is at the Hyundai Dealership in Evansville, In. 2. Loss or power in roadway. 3.Yes it has, by the dealership. 4.Yes, by the manufacturer & the Hyundai Dealership. 5. Yes, as I backed out onto the street all the dashboard lights came on and buzzers and alarms started going off. When I finally got the car in gear then I was able to drive it about 25 feet back into the driveway and I turned it off. I had to have it towed to the dealership and they would not stand behind the warranty for the engine & transmission.”

“While driving and everything is going along fine it will suddenly jerk and make a sound as if I've been hit behind. I'm not sure if it's part of the detached shift cables or transmission or something else. Sometimes it will jerk violently while going uphill also.”

“2012 Hyundai Sonata Hybrid well maintained by original owner, under 130,000 miles. May of 2025 AC stopped working intermittently (Hyundai dealer replaced AC hose). Aug 2025 AC stopped working AGAIN (same dealer could NOT identify problem). Car has consistent Hybrid System Warning! Safely Stop and Do not Drive messages lights and sirens when braking. Code PA186 comes up (low state of charge code for hybrid battery). December 2025 brought car back to SAME Hyundai dealer who NOW says car suddenly needs a 10k transmission (BUT still no idea what PA186 code is related to). Got transmission drained at different shop and NO NEW TRANSMISSION NEEDED! Every repair shop OUTSIDE OF HYUNDAI who has scanned for codes gets the PA186 error and say it is related to HYBRID BATTERY LOW STATE OF CHARGE (I am the original owner THUS lifetime hybrid battery warranty). June 2026 different Hyundai dealer for repair of AC and PA186 code. NEW Hyundai dealer says AC issue is NOT related to the PA186 code. They still dont know what PA186 code is but want to charge me $5100 for engine wiring harness electrical short. SIDE NOTE!! Engine wiring harness electrical short is known issue for ABS…”
