The retained reference is $1,299 current U.S. manufacturer price. Appliance-only reference before tax, delivery, countertop or cabinet work, gas and electrical work, LP conversion, regulator or connector scope, hood, make-up air, permits, installation and service plan; confirm exact E-number or revision, stock, return terms and authorized U.S. support. Have the seller and qualified trades confirm the complete installed scope before payment.

Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.

500 Series 30-Inch Gas Cooktop is retained when its exact 30-inch stainless drop-in cooktop, five sealed burners, continuous cast-iron grate coverage and a front-center knob bank create a denser field than bosch's four-burner 300 series and installed utility and service boundary fit better than the two defended alternatives.

What changed
Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.
500 Series 30-Inch Gas Cooktop was checked against current manufacturer identity and price, specification and installation material, support, independent category evidence, bounded owner evidence, ventilation and recall boundaries.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner evidence is retained as an installation, ignition, pan-fit, ventilation, cleaning and service checklist for 500 Series 30-Inch Gas Cooktop, not a cooking, emissions, failure or repair rate.
Reports are self-selected and span different fuels, conversions, pressures, regulators, connectors, counters, cabinets, cookware, food, hoods, make-up air, electrical work, cleaning and service regions. They cannot prove population cooking, simmer, speed, emissions, air quality, reliability, gas, fire, CO, electrical or repair outcomes.Self-selected owners and installers discuss five-burner crowding, continuous grates, OptiSim, flame monitoring and cleaning. Fuel, pressure, conversion, countertop, cabinetry, cookware, cooking load, hood, make-up air, cleaning and service region vary, so the reports cannot establish population cooking, emissions, failure or repair rates.
Confirm five-burner crowding, continuous grates, OptiSim, flame monitoring and cleaning on the installed exact model before treating the owner discussion as relevant.

Bosch identifies NGM5059UC as a mainstream 30-inch five-burner cooktop. Five sealed burners, continuous cast-iron grate coverage and a front-center knob bank create a denser field than Bosch's four-burner 300 Series
$1,299 current U.S. manufacturer price. Appliance-only reference before tax, delivery, countertop or cabinet work, gas and electrical work, LP conversion, regulator or connector scope, hood, make-up air, permits, installation and service plan; confirm exact E-number or revision, stock, return terms and authorized U.S. support.
The retained cutout is 28 15/16 inches wide by 19 1/8 inches deep; verify a supported counter, front and rear margins, clearances, connection space and any approved oven combination Five burners include a 16,000-BTU center and OptiSim position; actual pot overlap, grate seams and low flame must be checked with household cookware A qualified installer must match natural gas or the exact supported LP conversion, inlet and manifold pressure, regulator direction, shutoff, rigid supply and approved connector, follow permitted pressure and leak-test procedures without a flame and commission ignition and flame at every burner. If gas is smelled or ignition is delayed, stop use, avoid switches and flames, leave the area and follow the gas supplier or emergency authority instructions. Use the exact grounded 120 V branch or receptacle stated by the manual, never an extension cord and never defeated grounding. Electronic ignition, re-ignition, flame monitoring, lights and griddles can change behavior during an outage, so use only the exact model's documented outage procedure and close the gas shutoff before qualified service.
Core operation is local with electric ignition and thermocouple flame monitoring; there is no Home Connect cooking dependency Continuous grates, caps, ports, igniters and stainless surfaces require the documented cooled cleaning process, while exact E-number parts and recalls need ongoing checks
Consumer Reports retains current gas-cooktop tests including Bosch platforms and separates laboratory burner control from owner-survey reliability. This evidence informs the NGM5059UC comparison without promising the installed result.
Self-selected owners and installers discuss five-burner crowding, continuous grates, OptiSim, flame monitoring and cleaning. Fuel, pressure, conversion, countertop, cabinetry, cookware, cooking load, hood, make-up air, cleaning and service region vary, so the reports cannot establish population cooking, emissions, failure or repair rates.
Consumer Reports compares high- and low-heat control and ease of use under controlled conditions and keeps laboratory results separate from brand reliability surveys. A category method does not establish an untested exact model's result.
EPA identifies gas cooking as an indoor nitrogen-dioxide source and recommends correct adjustment plus an exhaust fan vented outdoors. This is risk-reduction guidance, not proof that a particular hood or kitchen produces safe air.
CPSC says never use a gas cooking appliance for heating and recommends battery-operated or battery-backup CO alarms on every level and outside sleeping areas. Alarms do not replace correct installation, combustion or ventilation.
Check the exact model, serial and revision against current manufacturer and CPSC recall records before purchase and during ownership. A search with no match does not guarantee that no future or differently scoped action will apply.

Manufacturer identity, exact current U.S. price and configuration, current specification and installation material, support, independent editorial or testing and bounded owner evidence were checked on August 21, 2026. This universe covers complete current U.S.-supported built-in residential gas cooktops and rangetops and excludes full ranges, portable burners, induction and radiant cooktops, commercial-only equipment, unsupported imports, retired or used-only products, package rebadges and duplicates created only by finish, knob, handle, natural-gas or LP suffix.

Burn, hot-surface, pan-handle, grease-fire, gas-leak, delayed-ignition, flash, combustion, carbon-monoxide and electrical hazards remain. No BTU, burner, simmer, speed, emission, air-quality, safety, cleaning, reliability or repair outcome is guaranteed.
