2026 INEOS Grenadier

Some 2023 Ineos Grenadier vehicles sold at auction were pre-production models with VINs that cannot be legally registered, surprising buyers who assumed they were standard dealer units. This leads to ...

The Grenadier lacks over-the-air (OTA) software update capability, requiring owners to visit a dealer for fixes like the New Year's glitch affecting all vehicles. This creates inconvenience and depend...

Access to the factory service manual requires submitting proof of ownership like a vehicle title, which is not immediately available after purchase, delaying access by months. Owners cannot promptly o...

The vehicle's computer systems lock out owner diagnostics and repairs, such as resetting service warnings, requiring dealer-level tools. This prevents self-maintenance and forces reliance on service c...

The physical service book omits key details on engine bay components, auxiliary battery, and charging procedures, despite covering unrelated topics like child seats. Owners lack essential maintenance ...

The owner's manual does not document procedures for resetting warning lights, leaving owners unable to address issues roadside without dealer help. This exacerbates breakdowns in remote areas.

Dealerships pre-purchase assurances of mobile repair and tow services proved false, with no actual support available during breakdowns. Buyers discover post-purchase that promised roadside assistance ...

The online owner's manual is inaccessible, extremely slow, or requires internet in regions like Australia, undermining its promotion for remote repairs. Owners in off-grid areas cannot rely on it when...

Ineos does not publicly disclose subscription pricing for connected services or features, preventing buyers from calculating true ongoing ownership costs before purchase. This opacity hides potential ...

The Grenadier's overspeed warning system alerts drivers when exceeding posted speed limits, but it triggers frequently during normal driving fluctuations around the limit. Owners report it reactivates...

Front parking sensors are meant to detect obstacles at low speeds, but they falsely trigger beeps randomly in drive or when wet, even at highway speeds. Owners disable them as part of startup routine ...

The low fuel warning system produces excessively loud bongs or chimes, activating too early or repeatedly, such as every unlock or on slanted surfaces. Owners compare it to deafening alerts and call f...

Disabling lane departure, driver monitoring, or other ADAS features triggers constant 'camera inoperative' or 'limited visibility' icons on the dash that owners hate. Lane assist chimes were added via...

The auto start-stop system, which shuts off the engine at stops to save fuel, lacks a permanent disable option and reactivates frequently, requiring workarounds like button levers or foot-off-brake tr...

Software glitches cause false or persistent service overdue alerts, like thousands of days overdue from a New Year's date bug or multiple confusing messages every startup that fail to reset. Non-essen...

Tire Pressure Monitoring System triggers false low-pressure alarms due to tire heat expansion in hot climates or off-road use, and prevents resetting while tires are warm.

Vehicle chimes loudly over bumps or tracks due to false rear door open detection, fixable by adjusting door stops.

The Grenadier's center infotainment screen experiences various glitches and malfunctions. Owners report frequent problems affecting usability.

The Grenadier's automatic HVAC mode always activates the air conditioner, even when heating is desired. Users must manually turn off AC first to get heat, which is by design per the dealer.

The online vehicle configurator omits prices for options, requiring buyers to contact a dealer for total build costs. This forces extra steps in the purchasing process.

The infotainment system's favorite button inconsistently navigates to the correct screen. Sometimes it works, other times it fails.

Wiper speed controls lack immediate response and intuitiveness. Users must wait for changes instead of instant adjustment.

Owners cannot reset service or oil reminders themselves after maintenance. A dealer visit is required, often costing extra like $70.

The HVAC system is not intuitive and fails to hold steady temperatures. It swings extremely between hot and cold.

Apple CarPlay disconnects unexpectedly during use on the infotainment system. This interrupts wireless connectivity.

An audible clicking sound plays when adjusting volume and cannot be fully disabled. This annoys users trying for quiet operation.

The infotainment touchscreen becomes washed out and illegible in direct sunlight. Visibility drops significantly in bright conditions.

The accelerator pedal has delayed initial response, complicating precise throttle control. This creates anxiety during low-speed off-roading like rock crawling.

Differential lock status uses wheel speed sensors, needing slippage to confirm engagement. This delays off-road mode access, requiring throttle adjustments.

The transmission shifter has an M/S marking suggesting manual or sport modes, but lacks actual Sport mode. It upshifts too quickly uphill.

The Grenadier's auto start-stop system automatically shuts off the engine at stops to save fuel and restarts it when accelerating. After a 2024 model software update, owners report it permanently stop...

Early Grenadier software had bugs causing instability. Updates have resolved these issues for some owners.

The INEOS Grenadier collects geolocation data from the vehicle depending on features and service availability. This tracks your vehicle's location, which owners may find invasive.

INEOS shares personal data including vehicle geolocation with group companies, dealers, service providers like Sirius XM, and data brokers. This enables connected services but raises privacy concerns ...

An opt-out is available for certain connected services data sharing, but any data already shared remains under third-party control. Owners cannot fully retract previously disclosed information.

INEOS retains contact, identity, financial, and transaction data for six years after the customer relationship ends, primarily for tax purposes. This extended retention may concern privacy-focused buy...

Deletion requests for personal data can be made, but INEOS may not fully remove it if needed for business, legal obligations, or backups. This limits owners' control over their data.

Personal data, potentially including vehicle data, is disclosed to law enforcement as required by law, court orders, or regulations. This mandatory sharing bypasses owner consent.

The Grenadier's infotainment system, which controls audio, navigation, and vehicle settings, randomly goes black and resets while driving. Owners report this as a persistent glitch even after software...

A software bug triggered at midnight on January 1, 2026, falsely displays 'service overdue' warnings for up to 1852 days despite recent maintenance. This affects the vehicle's service reminder system.

Multiple critical dashboard errors suddenly appear, including transmission error, engine control error, e-call error, power steering error, and PDC error. These indicate software instability in core v...

Orange warning lights flash intermittently for about 30 seconds before disappearing, requiring a full vehicle reboot (turning the car off and on) to clear them. This points to unstable software monito...

After swapping wheels, the Tire Pressure Monitoring System (TPMS) displays 'Tyre pressure sensor lost' errors with yellow warnings. This software fault fails to recognize tire sensors properly.

Apple CarPlay maps (Google or Apple) freeze and stop showing live position above 20 km/h, hanging without updating. This disrupts navigation functionality in the infotainment system.

The vehicle's altimeter displays wildly inaccurate elevations, such as showing a city as 70 feet below sea level when it should be 8-10 feet above. This software error affects off-road instrumentation...

The HVAC climate control system randomly blows very hot or very cold air inconsistently, requiring a full reboot (turn off before stopping, restart after) to function properly. Owners describe it as n...

The vehicle fails to save basic settings like warning preferences or driver configurations between startups, forcing manual resets every drive. This includes persistent service warnings re-enabling th...

The infotainment system fails to resume MP3 playback from the previous position after restart, instead playing a random file. This affects media functionality in certain variants like 24.1.
