Hyundai applies a Paint Protection Film (PPF) on new vehicles before delivery to dealerships. It provides a barrier between the paint and contaminants, such as rail dust, acid rain, and industrial fallout. In rare cases, the paint can become clouded under the PPF. These spots are the result of moisture trapped between the PPF and the paint.

What stands out
Owners have filed 27 body complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA body complaint has been filed on this vehicle in over 5 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering body 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.
A nationwide settlement (âSettlementâ) has been reached in a class action lawsuit against Hyundai Motor America (âHMAâ). The lawsuit concerns model year 2015 to 2017 U.S. specification Hyundai Sonata vehicles equipped with the Smart Trunk feature purchased or leased in the fifty United States or the District of Columbia (âClass Vehiclesâ). The lawsuit alleges that torsion bars on the Smart Trunk in the Class Vehicles are defective because they do not open a sufficient amount. . Defendant has denied these allegations.

The failure pattern owners describe
Paint failure is the dominant complaint. White pearl paint peels in large sheets from roofs, hoods, and side panels without impact damage, sometimes within 3–5 years of ownership. Owners describe rapid deterioration—small chips expand into much larger areas—and exposed metal rusting beneath. Dealerships acknowledge the problem as widespread across same-colored inventory yet invoke mileage limits to deny warranty coverage. A class action lawsuit against Hyundai alleges improper curing of white pearl paint on 2014-present models; the company has settled multiple claims by paying for repaints, effectively admitting the defect exists.
Panoramic sunroof deflectors detach or unbond from the track during highway driving. One owner experienced four separate failures despite three factory re-gluing attempts. The loose deflector causes the glass panel to rattle and risks falling onto following traffic. Repairs consist of re-gluing, which repeatedly fails.
Antenna caps detach and fly off at highway speeds; the cover is not sold separately, forcing full antenna replacement at roughly $500. Door handle end caps crack easily, with one vehicle experiencing two failures. A trunk latch seized in the open position after manual key release, and an owner rigged a rope tie-down. One report documents a passenger rear door lock becoming inoperable, and another owner reports their driver seat mounting screw loosening, causing the seat to rock. Interior door noise—knocking from speakers or hinges—persists on at least one vehicle. A roof frame failure appears in the complaint set, though detail is minimal.

Failure modes owners describe
Paint peeling and delamination
White pearl paint peels in sheets, chips, or bubbles from roof, hood, side panels, and door areas. Paint deteriorates rapidly without impact damage. Exposed metal shows rust formation. Multiple owners report identical issue on same model/color combination, with dealerships acknowledging the problem as replicated across inventory.
When: Typically starts within 3-5 years of ownership (first reports around 2019-2023 on 2016 models); mileage varies from under warranty period to 60k+ miles
Symptoms owners cite: Large peeling sheets from roof and hood; Bubbling paint above door windows; Rapid chip expansion without external damage; Paint flaking off in multiple locations; Visible rust beneath failed paint
Repairs/costs cited: Owners attempted dealership repaints; some charged out-of-pocket ($500+ estimated based on antenna replacement cost reference). Dealerships cite mileage/warranty limits to deny coverage despite acknowledging defect. Class action lawsuit ongoing against Kia/Hyundai for improper paint curing on white pearl 2014-present models.
Recalls/TSBs owners mention: Class action settlement with Hyundai paying for repaints in some cases, admission of extreme issue with improper curing of white pearl paint
Panoramic sunroof wind deflector detachment
Wind deflector becomes unbonded or loosely attached to the sunroof track, causing flapping or complete detachment while vehicle is moving, especially at highway speeds. Glue repair fails repeatedly. Glass panel rattles and risks falling off, creating hazard to vehicle and following traffic.
When: Occurs at low mileage (one report at 21k miles); happens repeatedly on same vehicles (one owner had 4 occurrences, another 3)
Symptoms owners cite: Deflector flapping or loose when sunroof open; Glass panel rattling continually; Deflector pulling or nearly coming off vehicle; Difficulty closing sunroof during malfunction
Repairs/costs cited: Factory repair applies re-gluing; owners had to attempt repairs themselves or seek multiple dealer visits. One owner required four people with tools to close sunroof after deflector failure. Temporary fixes with hand-holding or tying down reported.
Recalls/TSBs owners mention: Recall issued for panoramic sunroof wind deflector detachment; however, owners report recall repair failing repeatedly (3-4 times on same vehicles). Dealer claims no recall available in some cases despite recall existing.
Antenna cover detachment
Shark fin antenna cap flies off during highway driving. No retention mechanism prevents loss. Part is not sold separately; full antenna replacement required.
When: Reported at 83k miles; one report during vacation driving on Florida highway; low-mileage vehicles affected
Symptoms owners cite: Cap detaches and becomes airborne; Loss of antenna cover during highway operation
Repairs/costs cited: Full antenna replacement cost approximately $500; cover not sold as separate part. Part lost and unable to be recovered by owners.
Recalls/TSBs owners mention: Recalls exist on newer Sonata model years but not addressed on 2016 models despite identical design defect
Door handle end cap breakage
End caps on door handles break or crack easily. Defect repeated on same vehicle after warranty repair.
When: First failure within one month of purchase; second failure after warranty expiration (passenger side)
Symptoms owners cite: End cap breaks or separates from handle; Door handle becomes non-functional
Repairs/costs cited: Dealer replacement under warranty at purchase. Out-of-warranty repair quoted at $187.50 per door handle.
Trunk latch failure and inability to close
Trunk latch becomes stuck in open position after emergency manual opening via key. Cannot be closed normally. WD-40 lubrication ineffective.
When: Defect occurred after using manual key release due to initial latch/FOB failure
Symptoms owners cite: Trunk will not open via key fob; Trunk will not open via interior release button; Trunk seized in open position after manual key release; Stuck latch requires rope tie-down as temporary fix
Repairs/costs cited: Owner jury-rigged solution using rope to tie trunk closed; status of warranty coverage unclear to owner
Door lock inoperability
Passenger side rear door lock becomes inoperable, preventing door opening from inside or outside of vehicle.
When: At approximately 60k miles
Symptoms owners cite: Door cannot be opened from inside or outside; Lock unresponsive
Interior door noise and potential loose components
Persistent knocking or rattling sound emanating from right side door area, speakers, or dashboard, becoming more pronounced when window is partially down or on rough road surfaces.
When: Ongoing issue for extended period; no specific mileage noted
Symptoms owners cite: Knocking sound from inside door; Sound intensifies with road surface roughness; Noise present during vehicle motion on streets or highways; Sound possibly originating from dashboard area
Driver seat mounting screw loosening
Screw connecting driver seat to rail and car frame loosens and falls out during normal use, causing seat to rock and wobble.
When: No specific timeframe stated; discovered during normal entry/exit
Symptoms owners cite: Seat rocking and wobbling; Loose mounting screw
Repairs/costs cited: No repair pieces broken; only fastener hardware issue
Roof frame cracks
Roof frame broke in multiple locations on same vehicle; second occurrence reported (broke twice in four places).
When: Two separate fracture events on single vehicle
Symptoms owners cite: Roof frame structural cracks

Common questions
How serious is the body problem on the 2016 Hyundai Sonata?
It's a documented issue but not catastrophic. 27 complaints have been filed. Repairs average $1,500 and most owners catch it before it causes a breakdown.
At what mileage does the body typically fail?
Across the 10 complaints that reported odometer mileage, most body failures cluster between 32,000 and 67,000 miles, with the median around 60,000. A quarter of owners report trouble before 32,000; a quarter make it past 67,000. 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 $1,500 for body 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 body?
No active recalls currently cover body 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.
