This bulletin contains information about the proper removal of the windshield wiper blade protective cover on all models. If the protective cover is not removed correctly, there is a possibility of the rubber insert and rail spring becoming partially separated on the inner side of the wiper blade, which could lead to poor wiping performance and/or possible scratching of the windshield glass. Follow the procedure in this bulletin to properly remove the windshield wiper blade protective cover on all new wiper blades.

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering visibility on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Certain Hyundai vehicles may not be equipped with an immobilizer. This bulletin provides the service procedure to update the IBU/BCM (Integrated Body Control Unit/Body Control Module), to revise the OEM Hyundai burglar alarm system operation and ignition start logic, and installation of two anti-theft decals for the front windows.
full bulletin at NHTSA ↗This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.
full bulletin at NHTSA ↗The warranty coverage for the panoramic sunroof moving glass has been extended to 10 years or 120,000 miles from the date of original retail delivery or date of first use, whichever occurs first, and is valid for original and subsequent owners.

The failure pattern owners describe
The 2012 Hyundai Sonata shows a cluster of visibility and glass failures that span the entire vehicle. The most dramatic issue is spontaneous sunroof glass shattering—owners describe loud explosions or gunshot-like sounds while driving 45–70 mph on highways, with glass fragmenting into the cabin despite being protected by a sunshade. In multiple cases, state police and insurance adjusters found no evidence of external impact; one owner's sunroof continued shattering each time doors were closed. Hyundai has refused warranty coverage, claiming either the part isn't covered or that impact must have occurred.
Windshield and rear window distortion is equally pervasive. Owners report ripples, waviness, and optical illusions visible from the driver's seat that can mimic obstacles on the road or impair night driving. Service managers at multiple dealerships confirmed the distortion is present across 2011–2012 Sonatas, yet told owners that replacement windshields would show the same defect. At least two owners had windshields replaced under warranty only to find the distortion persisted.
One owner also experienced continuous interior fogging and out-gassing odors; the dealer attributed it to plastic off-gassing but repair attempts failed. A rearview mirror couldn't be positioned to see left-side traffic, and rear passenger windows shattered while parked, occurring twice on the same vehicle. Throughout these complaints, Hyundai either denied coverage or showed no willingness to address the root causes.

Failure modes owners describe
Spontaneous sunroof glass shattering
Sunroof glass breaks apart without any documented impact while driving at highway speeds or while vehicle is stationary. Owners report loud explosions, glass falling into cabin onto sunshade, and in some cases continuing to shatter when doors are closed. No evidence of external impact found by state police or insurance adjusters in multiple cases.
When: 31,060 to 66,400+ miles; occurred during highway driving at 45–70 mph and while parked in driveway/garage
Symptoms owners cite: Loud explosion or gunshot-like sound during highway driving; Sunroof glass completely fragmented or with large hole; Glass falling into vehicle cabin; Continued shattering when car doors closed; No visible point of impact on glass
Repairs/costs cited: Dealership claimed impact site found on front edge of sunroof in one case; insurance adjuster reported inconclusive. Hyundai denied coverage under warranty in multiple cases, claiming no warrantied part or that impact must have occurred. Some owners paid out of pocket or through insurance deductible.
Recalls/TSBs owners mention: Hyundai refused warranty coverage in multiple complaints; cited non-warrantied part status or claimed external impact. No recall issued despite owner references to NBC News coverage and forums documenting multiple similar incidents on 2012 Sonatas and other Hyundai model years.
Windshield optical distortion and ripples
Windshield contains visible waviness, ripples, or distortion that creates optical illusions and impairs visibility. Distortion is visible from driver's seat at an angle and affects view through passenger side of windshield. Rear window exhibits similar wiggly/distorted image when viewed through rearview mirror.
When: Present from day one of ownership; noted at 5 miles, 67 miles, and 290 miles
Symptoms owners cite: Wavy lines and distortion in windshield glass visible from driver's seat; Distorted image when looking through rear view mirror at rear window; Creates optical illusion that can be mistaken for obstacles in road (e.g., dog running into traffic); Ripples in glass that pick up headlights at night and distract driver; Dashboard reflection onto windshield impairs visibility in certain sun angles
Repairs/costs cited: Windshield replaced under warranty in at least two cases; distortion persisted after replacement in both. Service managers at multiple dealerships (Greer Hyundai SC, Greenville Hyundai SD, Capitol Hyundai SC) confirmed same distortion present in other 2011 and 2012 Sonatas, but advised owners that replacement windshields would be the same and replacement was not offered.
Recalls/TSBs owners mention: Hyundai customer service assigned case number 4861688 to one owner and closed case when referred to another dealer. Customer service stated that if enough complaints were filed, a recall would be issued to replace windshield. Service managers indicated distortion is present across multiple model year 2011–2012 Sonatas but no recall or TSB issued.
Windshield interior fogging and out-gassing
Windshield becomes continuously foggy from the interior of the vehicle. Dealer attributed fogging to out-gassing from plastic materials and solvents in the vehicle when heated. Smells and vapors accompanied the fogging.
When: 5,000 to 20,000 miles
Symptoms owners cite: Continuous interior fogging of windshield; Out-gassing odors and vapors in cabin; Fogging persists despite dealer repair attempts
Repairs/costs cited: Vehicle taken to dealer six times. Dealer attempted repairs but smells and vapors would not diminish. Manufacturer was notified and claim was filed on owner's behalf; outcome not documented.
Recalls/TSBs owners mention: Manufacturer notified; claim filed on owner's behalf. No resolution details provided in complaint.
Driver's side rearview mirror inadequate field of view
Driver's side rearview mirror cannot be adjusted to provide adequate view of vehicles approaching from the left side of the vehicle. Owner unable to see left-side traffic even after attempting all available mirror positions.
When: 10 miles (failure mileage); noted at 6,000 miles current
Symptoms owners cite: Mirror positioning does not allow driver to see left-side approaching vehicles; Owner must turn around and look over shoulder to see traffic; Issue present from very early ownership
Repairs/costs cited: Vehicle neither diagnosed nor repaired.
Rear side window glass shattering
Rear passenger window glass shatters spontaneously after doors are closed with no external impact or collision. Owner was sitting in driveway when glass shattered; also occurred while sitting in garage on a separate occasion.
When: 58,000 miles and earlier (June 2012 in driveway); repeated occurrence in same vehicle at different time
Symptoms owners cite: Rear passenger window glass shatters without external impact; Occurs when doors closed or while vehicle is parked; Can occur multiple times on same vehicle
Repairs/costs cited: Owner paid for first replacement out of pocket, thinking it was damaged. Second occurrence in garage; repair status not documented. One complaint notes vehicle was neither diagnosed nor repaired.

Common questions
How serious is the visibility problem on the 2012 Hyundai Sonata?
It's a documented issue but not catastrophic. 20 complaints have been filed. Repairs average $350 and most owners catch it before it causes a breakdown.
At what mileage does the visibility typically fail?
Across the 12 complaints that reported odometer mileage, most visibility failures cluster between 12,000 and 59,000 miles, with the median around 31,060. A quarter of owners report trouble before 12,000; a quarter make it past 59,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $350 for visibility repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to visibility?
No active recalls currently cover visibility issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
