Hello, new member posting for 1st time...
Bought my Sonata brand new on July 31 2016, added every extended coverage the Dealer offered so paid a fortune for it...I drive it about 2,000 miles a month for my job, 90% highway miles...never had an issue up until this past Christmas 2017 when I got my first system display message saying I had a Transmission Control problem and to seek service...Dealer said the error code P1776 was researched and they replaced the Oil Pump assembly..drove the car a few hundred miles and seemed to be OK
The following week (mid-Jan 2018) when I was driving home from S FLA, after about 100 miles of driving I stopped to get gas. When I tried to restart the car it was "dead" and I got the Check Hybrid System and the message about a Powertrain System issue and to seek service...it had plenty of power, but would not turn over and would not drive...I had to let it sit for about 45 minutes before it started again. Once it did, I drove the remaining 250 miles home. When I got there, I turned it off for a minute and tried to restart it. It was dead again, gave me the Check Hybrid System light and did the same thing about not starting.
Next morning it started right up so I took it back to the Dealer for them to try again. This time they said it was giving them an error message P1990. They kept it a week, this time they replaced the Oil Pump control, which I don't understand why that would cause the car to not start...but they said that seemed to fix the problem so I left with it.
This past Sunday (the first time I attempted to drive it since bringing it home) I drove about 120 miles and stopped to get a drink. Car would not start again, exact same issue as before with the Check Hybrid System and not "turning over" and would not drive....after letting it sit for 30 minutes, it started up and I AGAIN drove it back to the Dealer.
They say it is again saying it is a Combo error code of the P1990 and P1776. They escalated it all the way up to some National Tech support group and they are going to try a new Power Relay replacement.
Has anyone else had a similar issue? The dealership has been very nice and allowed me a courtesy car to drive, but I honestly am very concerned about not being sure what the issue is, and then driving long distances and not being sure the car will start if I want to use a restroom or eat....
Thanks for letting me vent, hopefully I am not alone in dealing with this.
