In January (Toronto, Ontario), I was averaging 195 miles (switched to 18" winter tires). Are you using the heating system at high levels, lots of highway driving, jack rabbit starts? It sound low (40% drop).

 

Main heating system is not being used now, it was during cold months that's why I didn't think much about 130 miles per 100% charge in the middle of a cold winter. Steering wheel is on occasionally but that barely uses any energy. 3.5 m/kwh like I said so I'm not racing around town and very little highway driving. Gotta be either a software issue or a battery issue. Just wondering if I'm alone on this issue.

 

It takes a while to catch up. When I started on my recent road trip, it predicted 390 miles of range. Each charge predicted a little closer to actual freeway range. By the time we finished our 3,400 mile trip, it was pretty close. But then it grossly underestimated for several weeks after we got home. I guess it's a sluggish GOM. 😊 I mostly ignore it and use the percentage.

 

160 ACTUAL driven miles or the estimated range display? If you are getting 3.5 mi/kwh you should be able to drive 262 miles. The ESTIMATED range is based on the efficiency over the past 300 ish miles.

 

Doing the math based on % battery left and miles driven, it's about 160 total miles, so the estimates for range left seems right. Anyone else have this problem. Going to the dealership on Thursday for the recalls and hoping whatever the issue is will be fixed or is covered under the battery warranty.

 

Unusually low range is often caused by a single bad cell in the battery pack. Battery issues can be quickly detected with a smartphone and obd2 bluetooth dongle:

The GOM (miles remaining) reading on the instrument panel is NOT ACCURATE. Your REAL TIME reading of 3.5 kWh is good for the Limited Edition and should give you are REAL TIME range of 260 miles (3.5 kWh x 74.1 kWh (usable battery)). If the GOM reading keeps being so LOW then get your car checked out. The GOM SHOULD be closer to your REAL TIME reading and is usually HIGHER.

 

Update. Did the recalls and mentioned range issue with service tech. They didn't do anything because no codes thrown. Two Saturdays ago got warning lights and error code P1AA700 for a battery management system error, battery won't charge past 80%, and it wouldn't take a charge. It's been at the dealership for a week, they cleared codes and charged it on 6/19. Charged to "100%"and showed only 150 miles of range. Got another error message from my bluelink app that battery wouldn't charge past 80% after it just sat for a few days. Sent documentation of all the errors to Hyundai customer assistance and they're in contact with the dealership about potential warranty battery exchange if not fixable. Hopefully they'll do most of the work with the dealership so I don't have to. Just glad it's not my only car because it'll probably be at the dealership for who knows how long now.

 

Sorry about the bad news. I would think they would give you a loaner for an obvious warranty issue.

 

It seems surprisingly hard to persuade the Hyundai service department that your battery pack is bad, often takes several visits until they finally admit a problem. Maybe a secret corporate guideline?

Strange, as any faulty cell is immediately visible even with a smartphone and cheap obd2 bluetooth dongle, so it might spare you a few unnecessary trips to the dealer. Screenshot is taken from this thread:

Not sure about this, at least in the US, Hyundai Dealers are not corporate owned. The techs and service writers would love to be able to wow customers with warranty work, it is easy money for cars that otherwise need little actual maintenance.

The problem is more likely lack of expertise/knowledge by the techs. They go by procedures written by corporate and unless they really know their stuff, may not know how to convince corporate that there is a problem if the procedures are less than adequate.
