2024 Ineos Grenadier Problems

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 contact owns a 2024 Ineos Grenadier. The contact stated that while driving at an undisclosed speed, the A/C was activated; however, there was extremely hot air blowing out of the vents. No warning lights were illuminated. The contact stated that the vents were extremely hot and that the air temperature from the rear vents was recorded at 175 degrees. In addition, the air temperature from the front vents was recorded at 132 degrees. The contact burned his right hand while recording the temperature from the vents. The vehicle was taken to the dealer, where it was diagnosed with an A/C system failure. The contact was informed that the A/C system needed to be replaced. The vehicle was being repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 11,000.

Windsheild experienced a thermal crack that followed the length of the windscreen defrost vent. The crack began at each end of the vent traveled up about 2 inches and went horizontally across to the other end of the vent. Outside temps were in the single digits and it was snowing. Windscreen defrost was on max in order to provide visibility.

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.

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 no issues were identified at that time. Upon inspection after the incident, the tie rod hardware was found loose, which could have resulted in a complete loss of steering control if not caught in time. This appears to be a known issue within the Ineos Grenadier community involving steering and tie rod hardware concerns. The failure presents a significant safety risk to vehicle occupants and others on the road, especially during off road or remote travel where recovery and emergency services may not be readily available.

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).

Vehicle doors are swinging open while driving with no warning. Door does not then latch close. This has happened with multiple doors at various times. All times passengers were seated where the door has swung open, including adults and children. We contacted the dealership multiple times without any concern or help with the issue. Was told our sales person no longer is with them. Prior to purchasing the vehicle we had a concern getting the vehicle to the dealer for service due to living out of state. We were told they would come get the vehicle for service. We now have a vehicle that we purchased 5 months ago and is not drivable. We were told to drive the vehicle 5 hours to the nearest dealer.

The rear door handles of the vehicle get stuck in the open position and do not always latch. When driving the vehicle the doors then swing open. Clearly this is a tremendous safety hazard. The dealer has tried to fix it, but has done so unsuccessfully.

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.

While traveling on a rough road I experienced a side curtain airbag deployment on our Ineos Grenadier. There was no impact or roll over. There was only one person in the vehicle, the driver, yet both the drivers side and passenger side airbags deployed along with the drivers seatbelt locking mechanism. The airbags never deflated, leaving the driver trapped in the vehicle. To exit the vehicle a knife had to be used to deflate the drivers side airbag. Over one hour later the passenger side airbag had never deflated and also required a knife to puncture it. If there was an actual roll over and water was involved, I fear that the occupants of the vehicle could not get out. Something is faulty with this system.
