In vehicles like mine, which are fitted with the auxiliary battery, the battery can burp acid through a breather tube. this tube is located in a place where the acid will be discharged onto the brake lines. At that exact spot, there is a rubber bumper secured with cloth tape on those brake lines, and when the acid soaks into the cloth tape, the tape serves to hold the acid directly against the brake lines. Even after apparently only one day, the acid destroyed the tape and the rubber, and stripped the paint coating off the brake lines. I found …

23V828000 · Electrical System:Wiring

Reported: 2023-12-07 (December 7, 2023)

Ineos Automotive Americas, LLC (Ineos) is recalling certain 2024 Grenadier vehicles equipped with the auxiliary switch package relay. The relay control wire may have been trapped under the relay power cable connection fastener during assembly, which can potentially damage the relay control wire insulation and result in a short.

Consequence: A short circuit increases the risk of fire.

Remedy: Dealers will inspect and secure the wiring, and repair or replace any damaged wiring as necessary, free of charge. Owner notification letters were mailed June 25, 2024. Owners may contact Ineos customer service at 1-919-296-3626.

Reported: 2023-12-29 (December 29, 2023)

Ineos Automotive Americas, LLC (Ineos) is recalling certain 2023-2024 Grenadier vehicles. Non-locking nuts may have been mistakenly installed on the steering rod ball joint.

Consequence: Loose or missing nuts can result in the steering rod ball joint disconnecting from the steering knuckle, causing a loss of steering and increasing the risk of a crash.

Remedy: Dealers will install locking steering rod ball joint nuts, free of charge. Owner notification letters were mailed June 25, 2024. Owners may contact Ineos customer service at 1-919-296-3626.

Incident Summary: I am reporting a recurring and dangerous failure of the vehicle’s lane-keeping/automated steering system.

Incident 1 (I-5 North): Traveling at 70 mph in the right-hand lane. Every few minutes, the vehicle initiated an unprompted steer to the left.

The HVAC controller failure causes risk of burn to passengers. When operating the HVAC system on Air Conditioning, the system will direct heat from the engine bay without any temperature management resulting in hot engine air being sent through the HVAC system and out to the vents. In some circumstances the hot air is only sent through the rear vents and other times the system sends hot air to all vents with a high variability of when this occurs. In one experience, the hot air was only sent to the rear vents causing the rear vent’s metal knob…

The rear differential cover is made from lightweight stamped metal. It hangs lower than the differential housing itself and includes a lip that can easily catch on obstacles. This design makes it particularly vulnerable to damage when driving on rough terrain, such as Class 4 state roads. A compromised differential cover may lead to fluid leaks, which can ultimately result in catastrophic failure of the rear axle assembly.

I have a 2024 INEOS Grenadier with the factory installed Tow Package. While the Grenadier does not offer an Electric Brake Controller as an an option, they do market the vehicle as being pre-wired to accept aftermarket controller thereby allowing the vehicle to pull the maximum tow weight of 7600 pounds. The problem is the wiring does not conform to US requirements with regard to the brake signal trigger and as a result it is not possible to activate the brake controller.

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.

No selected model years have a complete observation window. Choose an eligible year or a shorter window.

Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.

1. When the fuel tank is filled up, it triggers an Engine Warning Light which has to be manually reset for other functions (like cruise control to operate). I've been waiting 4 months for a fix. 2. After numerous attempts, the dealership is unable to have the installed recommended break Controller (Redarc) successfully send a break signal to the towing wiring harness, meaning that I cannot tow vehicles safely in line with the vehicle's advertized specifications. I have left my vehicle with Mossy Inneos Houston and said I don't want it back unt…

I have a 2024 INEOS Grenadier with the factory installed Tow Package. While the Grenadier does not offer an Electric Brake Controller as an an option, they do market the vehicle as being pre-wired to accept aftermarket controller thereby allowing the vehicle to pull the maximum tow weight of 7600 pounds. The problem is the wiring does not conform to US requirements with regard to the brake signal trigger and as a result it is not possible to activate the brake controller. This is a known manufacturing defect affecting every Grenadier sold in t…

In vehicles like mine, which are fitted with the auxiliary battery, the battery can burp acid through a breather tube. this tube is located in a place where the acid will be discharged onto the brake lines. At that exact spot, there is a rubber bumper secured with cloth tape on those brake lines, and when the acid soaks into the cloth tape, the tape serves to hold the acid directly against the brake lines. Even after apparently only one day, the acid destroyed the tape and the rubber, and stripped the paint coating off the brake lines. I found …
