General Motors has issued a service update for select units of the 2023 Chevy Tahoe PPV following an issue with the full-size SUV’s surveillance mode.
On affected Tahoe PPV units, surveillance mode may not be enabled. As such, certified GM techs are tasked with reprogramming the body control module to address this issue, which should take them under an hour to perform. As of the time of this writing, it’s unclear how many units are affected by this service update.
It’s worth noting that GM assigned this service update with N232408732.
As a reminder, the Chevy Tahoe PPV, or Police Pursuit Vehicle, is outfitted with all sorts of law enforcement-related goodies, including a heavy-duty rear differential, a heavy-duty braking system with Brembo six-piston front calipers and 16-inch rotors, Firestone Firehawk Pursuit tires, and a performance suspension setup intended for pursuit.
Under the hood, the naturally aspirated 5.3L V8 L84 gasoline engine, rated at 355 horsepower and 383 pound-feet of torque, pairs with the GM 10-speed automatic transmission and directs output to either the rear wheels or all four.
Some notable upgrades for the engine include the supercharged 6.2L V8 LT4 engine’s rocker covers, which improve crankcase ventilation, and a heavy-duty oil cooling system, developed specifically for law enforcement applications.
Of course, connectivity and safety features are vitally important for police officers, so the Tahoe PPV is equipped with the OnStar 4G LTE Wi-Fi Hotspot, standard rear vision camera with Rear Park Assist, Hitch Guidance trailering system, an available Rear Camera Mirror, a 760-amp auxiliary battery, and new high-output alternator.
Production takes place at the GM Arlington Assembly plant alongside the civilian-spec Tahoe, as well as the rest of General Motors’ full-size SUV lineup.
