A Drive report warns that mobile carriers could begin decommissioning LTE networks as early as 2030, potentially cutting off services in cars that rely on 4G modems. The timing and effects for specific vehicles are not established, but a 4G radio cannot connect to a 5G-only network, so automakers may need to plan for the change well ahead of time.

Mobile carriers could begin retiring 4G LTE networks as early as 2030, a prospect that may leave connected-car services without a network in vehicles built around LTE modems. The Drive has raised the issue using connected-vehicle market estimates and comments from Omdia analyst John Canali; no universal shutdown date or confirmed list of affected cars is provided.

The report says there are about 500 million connected cars worldwide and that the total is expected to more than double by 2035. Those figures describe the connected-car market; they do not establish how many vehicles would lose service if LTE networks are retired. The report does not identify carrier-by-carrier schedules or specific makes and models that would be affected.

Vehicles use connectivity for functions such as remote services, tracking, diagnostics and infotainment. If a feature depends on a cellular connection, losing access to the necessary network could make that feature unavailable even if the car’s hardware still works. The consequences would vary by vehicle and service; the source does not say that cars would stop operating mechanically or become undrivable.

The hardware limit is central to the concern: a 4G modem cannot connect to a 5G-only network, and a software update cannot change a 4G radio into 5G hardware. The Drive argues that automakers should account for possible network changes while planning future vehicles. It also raises, as a suggestion rather than an announced plan, the possibility of a shared network arrangement to support older vehicles.

Connected Features Face a Hardware Deadline

The issue could affect owners well beyond the date when carriers make network changes. A vehicle that remains mechanically sound may still lose some network-dependent functions if its modem cannot access a supported network and no alternative connection is provided. That could change how useful some remote features are and could influence a used car’s appeal, though the report offers no estimate of resale losses.

Planning lead times matter because automakers develop vehicles years in advance. Decisions about modem hardware, software support and service lifetimes made now could shape whether future models can keep working across network generations. For owners, the practical impact will depend on the car’s design and which services rely on LTE; the source does not establish that a shutdown would disable core driving systems.

Lessons From Earlier Network Retirements

The Drive points to the 2022 shutdown of 3G networks as a precedent: it says connected features in millions of cars were affected. The report also notes that early OnStar-equipped vehicles lost service after an analog network shutdown in 2008. These examples show that cellular services can outlast neither the networks nor the hardware they depend on, but they do not prove the scale or timing of a future LTE impact.

Canali, an Omdia principal IoT analyst, said in a press release that automakers are moving toward software-defined vehicles and exploring connectivity technologies such as eSIM and terrestrial/non-terrestrial networks. He also said 5G adoption has been slow and warned that LTE decommissioning could leave vehicles dependent on connectivity without a viable network. His comments describe a risk, not a confirmed outcome for all LTE-equipped cars.

Shutdown Dates and Vehicle Effects

The source says carriers are expected to start decommissioning LTE as early as 2030; it does not name operators, countries, confirmed dates or the pace of any retirement. Network plans may differ by market, and the report gives no confirmed timetable for when LTE would become unavailable to automotive customers.

It is also unclear which vehicles would lose which functions, whether automakers or service providers could offer replacement hardware or network arrangements, and whether affected services would continue through other technologies. The article raises possible difficulties for used-car owners, but does not quantify financial effects or establish that a particular car will become unusable.

Automakers Must Plan for LTE

The next concrete developments to watch are carrier announcements on LTE retirement and automaker guidance on modem support, service end dates and upgrade options. The supplied report does not describe a confirmed industry response, funding plan or proposed “network classic” system; that concept is presented as the author’s suggestion.

Owners can check their vehicle maker’s service notices and connected-service terms for information about their own model. Until carriers publish schedules and automakers explain their plans, the scale of any effect remains uncertain. The central question is whether vehicles designed around LTE will have a supported way to connect when networks change.

Key Questions

When could 4G LTE networks start shutting down?

The report says carriers are expected to begin decommissioning LTE as early as 2030. It does not identify confirmed dates or schedules for individual carriers or regions.

Would an LTE shutdown make a car undrivable?

The source discusses possible loss of connectivity-dependent services, including remote features, tracking, diagnostics and infotainment. It does not establish that cars would stop driving or that core mechanical functions would fail.

Can a software update make a 4G car work on 5G?

No. A 4G modem cannot connect to a 5G-only network; software cannot turn its radio hardware into a 5G modem. Whether another upgrade or service option is available would depend on the vehicle and provider.

Which cars will be affected?

The report does not list affected makes or models. The impact would depend on each vehicle’s modem, services and local network plans, none of which are mapped out in the source.

Have automakers announced a solution?

The supplied report describes no confirmed industry-wide solution. A shared system to support older 4G vehicles is suggested by the author, but no consortium or program is announced.
