Hyundai Sonata Change Vehicle

"It worked fine for 14 months. Then it would not connect or stay connected. the dealer had it back 4 times to try to fix it. They replaced the USB plug, to no avail. They tried to get it to work, and were able to get it to connect after 4 tires but couldn't duplicate it. They sent me to Samsung. Samsung sent me to Hyundai Bluelink, which couldn't fix it. The Blue link people finally decided that my phone is no longer compatible with my car, and that there was no fix"

"A confusing system to operate. When a check or fix is executed in another area (e.g. tire pressure) it often returns to default Android Auto settings and is difficult to get back to my preferred settings. In fact, some of the settings don't seem to work any longer. And none of the service people ta the dealer seem to have a clue."

"I can not get the system to work properly , I use my Garmine most of the time."

"I can't see very far ahead of the car at night. I have over 2 million miles behind the wheel and this is the first car where I can't see signs, animals, or exits ahead of me so I do not drive this car at night time because it is so dangerous. I can only see 3 white lines ahead at a time and twice I had a dealer check them and they said they were in specs."

"We are having to replace the driver side map light."

"There was a computer self check that failed intermittently. Had to take it to the dealership twice before it started to fail more regularly. The computer system was replaced under warranty. No other issues have shown up."

"Depending on Dealer/Factory investigation, engine may need to be replaced."

"14 March 2018 10:30 AM, 70 mph on US 101 to San Francisco, HEV mode, rainy weather, 4 passengers for a business meeting. Car steering shuddered as if the tires slipped and spun on the wet pavement. ESC, Brake, and Auto Hold lights turned yellow. Was able to drive the car normally to reach destination, parked, attended meeting, and started driving back home with my passengers at 3PM. ESC, Brake, and Auto Hold lights were still on. HEV mode. 30 minutes later, I-280 at 65+ mph, engine power drastically reduced abruptly, car started to slow down and became unresponsive to the gas. Turned on Emergency Flashers and with great difficulty in the evening rush hour commute traffic, managed to shift right three lanes and take the next exit, went into a parking lot and stopped the car. Consulted manual for any meaningful actions. Started car back up. MIL light also came on along with message to take car to dealer. Ran Vehicle Diagnostics and got “a possible condition with the ECS has been detected and a full system check is recommended soon”. Started driving car again. Same lack of engine power. Drove through local roads and countless many traffic lights and reached home after 4 hours (normal = 1 1/2 hours). At home, plugged car in for charging. Charging started normally. Around 10PM, wanted to take a picture of all the lights, so pulled charging cable out and started car. All lights were OFF except MIL! Decided to test drive and found no loss of power. Took it to nearby freeway, floored gas pedal. Car responded with full power! The following day, when I started driving the car to the dealer, the car dashboard filled with warnings with sound alerts about the failure of HEV system, asking me to stop the car immediately and tow it to the dealer. I proceeded to drive it slowly to the dealer. The final diagnosis is the failure of the engine crankshaft sensor! Since its replacement, the car has been running fine, but I can’t help but have the uneasy feeling of when it might fail again."

"This morning around 10:30AM, driving at over 70 mph to San Francisco in the rain with 4 passengers for a business meeting, my 2017 Sonata PHEV shudders as if the tires slipped and spun on the wet pavement. I noticed that the ESC light was yellow and also a little while later, the Brake light and Auto Hold lights turned yellow. I thought I had accidentally hit the Auto Hold button and had to wait for an opportunity to press it while pressing the break to eliminate the light. When the opportunity came, I could not get the light to go off. Also, tried turning ESC off and on again but the light stayed on. Parked the car in the garage, went to the meeting and came back at 3PM, and started back the drive home with my passengers. All the above lights were on. About 30 minutes later, in the 6 lane I280, all of a sudden the engine power drastically reduces abruptly and the car starts to slow down. With great difficulty in the evening rush hour commute traffic, I managed to shift lanes and take the next exit and went into a parking lot and stopped the car. After a few minutes, start it back up and now the MIL comes on along with a message to take the car to the dealer. Ran the Vehicle Diagnostics and get the message of possible condition with the ECS. Start driving the car with the same lack of engine power. Drove through local road and reached home after 4 hours for what should have been a 1 1/2 hour trip. On the way back, called Bluelink and they confirmed the need to take the car to the dealer and made an appointment for me for tomorrow. I wanted to take a picture of all the lights, so around 10PM I started the car, and all the lights are GONE except MIL. Decided to test drive the car and found no loss of power. Took it to the nearby freeway and floored it with full power response! Here is the write up from the dealer: Duplicated engine light is ON, scanned for codes and P033500 Crankshaft position A circuit P0A0F Engine failed to start C164808 CAN signal error HMS ACC SCC CL35808 HCU Torque control unavailable for SCC C13 6081. Cleared codes and then test drive vehicle. Only code that came back was P033500 Crankshaft position sensor A circuit active. Checked harness OK. Pulled sensor and is dirty, but when performing active monitoring on tablet would not show it cranking on or signal. Recommend replacing crankshaft position sensor and check. Replaced crankshaft sensor and test drive vehicle. No lights came back on. Recheck for codes. All clear. Operates as designed at this time. Any way, got the car back today and I hope this really was the root cause. I have a hard time though seeing the sequence of symptoms that I saw are explained by this as the root cause."
