Replaced third brake light on my 2023 Genesis GV70 3.5T Sport Prestige after the upper liftgate-mounted CHMSL had three LED elements burned out and I failed state inspection. Vaz confirmed the GV70 trim and mounting location specifically. Sourced from a 2023 GV70 3.5T Sport Advanced donor (same year, similar trim, same upper liftgate mounting). All LED elements functional, lens crystal clear, gasket sealing perfect. Installed myself in 35 minutes following the liftgate trim removal process. Pass

Bought third brake light for my 2024 Electrified GV70 (the fully electric variant added 2023, with 429 HP and E-GMP-adapted platform). Vaz emphasized that the CHMSL is the same component on both ICE and Electrified GV70 variants (third brake light doesn't depend on powertrain). Sourced from 2023 Electrified GV70 donor. One star off because Electrified GV70 donor availability is limited (newer EV variant, smaller donor pool) and sourcing took 14 days. The Genesis brand context and 800V architectu
What is FMVSS 108 and why does it matter?
FMVSS 108 (Federal Motor Vehicle Safety Standard No. 108) is the US federal regulation governing automotive lighting and reflective devices. It mandates that all passenger vehicles sold in US must have a center high-mounted stop lamp (CHMSL, third brake light) since 1986 model year. Studies prior to mandate showed CHMSL reduces rear-end collisions by 4.3% by providing more conspicuous brake signal especially when lower brake lights are obscured by vehicles in between. The CHMSL must be operational for vehicle safety inspection in most states. A non-functional CHMSL can fail state inspection and may result in traffic citation.
My GV70 third brake light has one LED out. Can I drive like this?
Technically illegal in most states (CHMSL must be fully functional per state vehicle codes and FMVSS 108). However, partial LED CHMSL still provides brake signal visibility - it's not a complete failure. Recommend prompt replacement. Continued operation with partial failure may lead to additional LED failures, complete failure, traffic citation, or insurance complication if rear-ended (defense attorney may argue partial brake signal contributed to collision). LED CHMSL units typically cannot be repaired (sealed units), require complete assembly replacement.
What's the difference between ICE GV70 and Electrified GV70?
Major differences: ICE GV70 - traditional internal combustion engine (2.5L Turbo I4 or 3.5L Twin-Turbo V6), 8-speed automatic transmission, AWD standard, conventional fuel system. Electrified GV70 - fully electric (BEV), E-GMP-adapted platform with 800V architecture, dual-motor AWD, 429 HP combined power, battery thermal management system, no engine/transmission/exhaust. Different cooling systems (Electrified has battery/motor/electronics cooling vs ICE engine cooling). Electrified launched 2023 model year. CHMSL is the same component on both (third brake light doesn't depend on powertrain) - mounted same locations on both variants.
How does GV70 compare to other Genesis SUVs?
Genesis SUV lineup: GV60 = COMPACT ELECTRIC luxury crossover (fully electric only, E-GMP platform). GV70 = COMPACT luxury SUV (ICE variants plus Electrified added 2023). GV80 = MID-SIZE luxury SUV (ICE only, 2.5L Turbo or 3.5L Twin-Turbo V6). All compete with German and Japanese luxury SUVs. Number indicates increasing size: 60 < 70 < 80. The 'V' prefix indicates SUV/crossover (vs 'G' alone for sedans G70/G80/G90).
What's the difference between 2.5T and 3.5T GV70?
Engine difference: 2.5T = 2.5L Turbo I4 engine (300 HP). 3.5T = 3.5L Twin-Turbo V6 engine (375 HP). 3.5T trims are higher-performance Sport oriented. CHMSL is the same physical component on both engine variants - third brake light doesn't depend on engine choice. However, trim-specific differences may exist in spoiler design or liftgate styling that affects exact CHMSL mounting. Specify your trim at order so we can match correct mounting configuration.
How do I install the third brake light?
Process (varies by mounting location): For LIFTGATE-MOUNTED: (1) Open liftgate. (2) Remove interior liftgate trim panel (clips and screws). (3) Locate CHMSL from inside. (4) Disconnect electrical connector. (5) Remove mounting bolts/clips. (6) Push CHMSL outward through opening. (7) Install new CHMSL through opening. (8) Mount with bolts/clips. (9) Connect electrical. (10) Test before reassembling trim. (11) Reinstall trim panel. For SPOILER-MOUNTED: requires spoiler removal first (more complex), additional steps for spoiler reinstallation. 30 minutes for liftgate-mounted, 1 hour for spoiler-mounted at shop.
How long does an LED third brake light last?
LED CHMSL typically lasts vehicle lifetime (20+ years of normal use). LEDs have very long service life (50,000+ hours) and are not subject to the filament burn-out of incandescent bulbs. Most LED CHMSL failures are due to: (1) Water intrusion damaging LED PCB (failed gasket). (2) Physical impact damage (cracked lens, broken mounting). (3) Electrical issues (failed driver/control circuit). (4) Rarely, individual LED failure with age. Genesis GV70 LED CHMSL should last vehicle lifetime if not damaged.
How does shipping work?
Free shipping to all 50 US states. CHMSL weighs 0.5-1.5 lbs in padded box with lens protection. UPS or FedEx Ground. 3-7 business days. Bubble wrap and lens protection to prevent damage in transit. Some larger spoiler-mounted variants may use slightly larger packaging.
