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 the US. I have contacted INEOS regarding this matter and this is their reply: Hi [XXX] , Thanks for contacting INEOS Automotive. I have heard back from the relevant team and our team are aware of the issue. Unfortunately there was no ETA given for this but there are plans to look into this issue further. Please don't hesitate to contact us for any further assistance. Best regards, INEOS Automotive Customer Care Team This is not an acceptable response for addressing a manufacturing defect.

The brake warning light came on as the vehicle was failing. It did not give me any warning prior, I was leaving my driveway to go to the market when this light indicator came on and my brake I could tell was failing because I had put my foot all the way down on the floor, so I decided to not go to the store and back in and I was having trouble all the way down my driveway with the brake my boyfriend examined the vehicle and underneath the front and rear axle. Both the line had holes in it so that was from the line rubbing against the wheel well and that was the way the car was built so when he went to go check the brake fluid underneath the hood. The reservoir was completely empty, and there was brake fluid gushing everywhere down the driveway because I went to go look out front and there was just brake fluid everywhere. I would’ve if I would’ve went to the store, I would have not had brakes and I live in an area where there’s a lot of hills. I could’ve not only hurt myself, but have hurt someone else.

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 it before it caused an issue, but the train location for the battery breathers is a problem. - My picture and forum post, also - [XXX] U.S.C. 552(B)(6) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 until it can safely tow trailers as advertized.
