Any news since September 8, 2022? My 2016 Sonata Plug-in Hybrid has all of the problems listed above. Has been at the dealers since August 1st. 2022. They have now decided my car does need a new battery and will install it upon arrival. They now say March 2023.

Has anyone actually gotten a new battery?

Thanks

 

Has anyone actually gotten a new battery?

Not here. The last time I spoke with them, they said February. But they didn't sound confident. Part of me hopes they wait until April because then my car will have been at the dealer for a full year - and I like round numbers!

 

I had that exact issue with my 2021 Santa Fe Hybrid last summer. I took it in for service, they could not find anything wrong. After several trips to the service center, I learned that Hyundai had a fix. They changed the fluid in the system on the last visit. I haven't had an issue since. We're in our cooler season in Florida right now so we'll see how the fix works in the summer months.

 

I should also mention that I got a call direct from Hyundai (not the dealer) about this issue. All they wanted was to verify that my car was at the dealer and that I had been given a loaner.
I took it to be a call checking to make sure the dealer was doing what they were supposed to be doing. (And they are)

 

My saga has finally ended. Since my last post in August, I took the car back to the dealer after the alert continued. Also the range was down to 18 mi. The dealer informed me Hyundai would not provide a loaner since they could not determine the issue was under warranty. I contacted Hyundai corp customer service and after they did not agree to cover a loaner, I decided to make a lemon law claim and informed the rep to start the process. Five months later, I turned the car in yesterday and was provided a check for the buy back based upon the value when it first started having problems which was at 12k mi. I did not use an attorney since Hyundai was cooperating and courteous, but I contacted one to review it and he said there was a solid case for my claim. The process is very long especially with the claim rep that I was assigned, but overall Hyundai was fair about my claim and did not contest it. I kept and provided all records to them timely which made it smoother but still took awhile. The last 2 weeks I had the car another hybrid battery warning light appeared and the car shut down immediately. It occurred twice and is a major safety issue. Fortunately I was in a place where I could pull over safely. It restarted with the start button but the check engine was on. The next time I started the car, the light was not on. It was random and unsettling. If you consider filing a claim, research the lemon law rules in your state. There are time limits and other rules about how it’s determined including covering legal fees. CA has a very consumer protective lemon law with a standard calculator to determine the value and it includes legal fees to be paid by the manufacturer. Also, I had the car in my possession and it was operable during the process which made it easier to be patient, but I had to be persistent with Hyundai to get updates.

 

My saga has finally ended. [...]

Thanks for this update! I've been wondering if Hyundai would be willing to simply buy the cars from people who have experienced this failure - especially if the number of cars affected grows.

I'm thinking now that I was lucky to get in early. And I'm wondering if Hyundai is starting to push back harder on failures now that more of them have popped up...

 

I wonder what Hyundai does with these "buy back" cars? I assume they just clean 'em up and put them back for sale on the dealer lot - so sad if the new owner inherits the problems...

 

My battery is supposed to be replaced in march 2023. They did not give me a loaner. I got the same call from national hyundai telling me that it was moved from february 2023 to march 2023.

 

Hi. Ohio 1st owner of a 2017 sonata plug in hybrid with 29k miles. Brought in to dealer Jan 2022, told needed new battery pack Feb. 2022. Still waiting now March 2023. Car has on 14 occasions loss all motive power while driving. Several times has lost braking power with severe shuddering. The 1st issue, which began at 3 to 4 years, was the "High System Temp. Switching to Hybrid Mode" others mentioned. Car was at dealership for 9 months in 2022 and I had a loaner....then dealer wanted their car back and my car off their lot. HMA initially agreed to pay for a rental...for 6 weeks. Then someone from corporate stepped in and nixed that (but did reimburse the 6 wks to that point). Last summer and now recently they have tried to buy back car but their methodology is flawed and puts NO value in the Lifetime Hybrid Battery Warranty. They couldn't give a darn about my or anyone else on this forum's safety....if they did, we would all have loaners. I did notice a class action filed last month in Maryland about this same issue. Fyi: range: decreased to 19 by the time I took in to dealer in Jan 2022. Since getting car back in October, range has now dropped to 13/14. Not exactly sure what I will do....but I am MUCH less believing that they will actually produce the battery pack for this make/model as it has been discontinued.

 

Thank you for this information. Details of class action lawsuit as follows: Hyundai Sonata class action claims automaker fails to honor lifetime battery warranty

 

Same goes for the 100K warranty really. They can't put their actions where their advertisements are. They seem to blame Covid and supply chain issues etc so far like many other companies. They would probably report abuse somehow to not honor, and don't cover anything as well. Thank goodness for that lawsuit. They can't even fix their white paint or blown up ICE motors as well.

 

That is really discouraging news...my 2016 PHEV has been at dealer since 11/9/22 waiting for new battery, which was supposed to be available in March. Last week I was told it is still on "backorder" which means it has not yet been shipped from Korea.

 

And the saga just keeps getting worse and worse....Hyundai told me that they have no idea when the battery is arriving. Then then said they would buy back my car. I had to send them a whole bunch of documents and they came back with an estimate that I would have to "pay them over 1400 dollars" to buy back my car. Their basic formula was (cost of car-mileage adjustment based on full price of car-rebates). Their formula is based on the idea that at 100,000 miles the car is worth nothing.... Ridiculous...

Anyone know anything about the status of the class action lawsuit?
Anyone actually gotten their battery replaced?

How many miles do you have? Useful life is the extent of the 100k warranty. If you get more value after 100K then you're lucky evidently. I know they've had to extend some warranties (ICE) to over 100K (like 150K/15) so perhaps they need to address their formula for that reason alone.

 

While only peripherally related to our issue, I thought some of you might be interested in this news item:

I just got my 2016 Sonata PHEV back from the dealer with a new battery, after waiting 7 months, 3 weeks! I was fortunate to have had a loaner all that time. So Hyundai is shipping new batteries, but I assume there is still a backlog, because there were still a couple of PHEV's at the dealer awaiting their batteries.

 

Indeed. I'm coming up on 16 months, but my battery is at the dealer right now. In perhaps a week or so, I should have my car back! (famous last words)

 

My saga is complete! After 16 months, I got my car back today. The system reports around 27 miles of range (which is what it was when it was new). We'll see if it holds, but I expect it will.
Throughout it all, the local dealer (Dick's Hyundai in Hillsboro, OR) were great. They had to replace the 12V battery since it had sat idle for so long - but they got Hyundai to pay for that. They also threw in a bit of detailing and comped me the half-a-tank in the loaner (since I hadn't bothered filling it up before rushing over).

 

wow - good to hear. Unbelievable it took 16 months to repair a bad battery pack.
