Owner report 11611042 · 2024-08-26 (August 26, 2024)
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 …

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.

Owner report 11602831 · 2024-07-16 (July 16, 2024)
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…

Owner report 11566813 · 2024-01-21 (January 21, 2024)
Driving at highway speeds--55-65 mph--the vehicle is all over the road. I am very concerned that there is a problem with the steering engineering making this vehicle dangerous on highways (as opposed to off-road).

Owner report 11737172 · 2026-05-11 (May 11, 2026)
While driving my Ineos Grenadier in the middle of the Arizona desert, the steering suddenly became difficult to control due to a tie rod nut coming loose. The vehicle began wandering and required constant correction to maintain control, creating a serious safety concern in a remote area far from immediate assistance. There were no warning lamps, messages, or alerts displayed inside the vehicle before or during the incident. Just one week prior, the steering and front end components had been inspected by an authorized dealer during service, and …
