I have a 2024 INEOS Grenadier with the factory installed Tow Package.

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 mecha

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.Read more

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 circumst
... ances 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 to become very hot and resulted in my child burning their hand on the knob. The dealer has confirmed the issue on my vehicle and has ordered parts under warranty (currently on backorder for 30+ days) to resolve. The issue of the HVAC unit blowing hot air is common to many Ineos Grenadier vehicles according to the dealer and is also commonly raised on Grenadier vehicle forums. The immediate safety risk occurs when the heat is not apparent to the driver because the controller is only directing heat to the rear and the vent knob becomes a burn-point for passengers. This issue can occur regardless of the temperature setting on the driver controls whether being on auto or manual and the temperature setting of the HVAC set as cold air. My vehicle is available for inspection if requested.Read more

Well known fault is the door opening buttons stay pushed in. Ineos dealer solution is either to dust them graphite dust (which does provide temp relief) or strike the outer door body with fist to free the door (which does relieve the acute condition. Recently while driving with a passenger in the fr

My passenger was strapped in by seat belt but was leaning on the door arm at the time and was left unsupported to her right and fell towards the road. Only stopped from falling out by the belt. There was no visible or audible warning that the door was not securely locked but the button was stuck in so the door would not latch. I believe that Ineos have a fix and should be made to install on all vehicles. three out four doors are effected by this problem.Read more

The exterior door handle button on all 4 passenger doors becomes stuck and prevents the door latch from functioning properly when the door is closing as it fails to latch to the receiver mechanism on the door frame. This has occurred on both left and right rear passenger doors on my INEOS Grenadier
... and hundreds of others have reported this issue as well occurring with all 4 doors. On Saturday, [XXX] we were going to an event and a friend we picked up closed her left rear passenger door. The dash panel showed no issues (door ajar, etc.). While driving down the road and going into a turn, the left rear passenger door opened up fully and the passenger, had she not been using her seat belt, could have fallen out of the vehicle when she (by instinct) went to reach for the interior door handle and close the door. It required the right rear passenger to grab the left rear passenger (a [XXX] woman) to prevent left rear passenger from getting hurt, falling out, etc. Later that day in the driveway we attempted to replicate the issue but could not. On [XXX], when opening the right rear passenger door, the exterior door button stuck when pressed in and remained stuck, preventing the door from "locking" or allowing the latch to make contact with the receiver mechanism. The dash panel never displayed door ajar or alerted with any type of warnings. I was able to exit the driver seat and quickly identified the door button was fully pushed down and locked into position and I could open/close the door with no locking occurring over 10+ times of opening/closing door. I pushed button several times and it remained stuck in the depressed state. I had to with my fingers move it left to right, up down, etc. before it popped out and then began functioning normally again.

On [XXX], while driving at a slow speed and not in the vicinity of other vehicles, I heard a sudden cracking noise and noticed a crack had appeared on my windshield. I subsequently took the vehicle to SafeLite Glass Repair, where they informed me that the glass required replacement. Upon reviewing
... the INEOS FORUM, I observed that numerous owners have experienced the same crack in the same location without any indication of impact. The consensus among forum members is that these are stress cracks. I provided the attached .pdf documentation to INEOS; however, they declined to address this issue under warranty insisting there was impact. It is not realistic that MANY cars have cracks in the same exact place. I can confirm with certainty that there was no impact causing the crack. My driving speed was insufficient, and there were no objects around that could have impacted the windshield. The resulting crack in the windshield poses a potential safety risk by obstructing the driver's view. The vehicle has been inspected by both SafeLite Glass Repair and our INEOS dealer (MileOne INEOS in Maryland). The issue was also reported to corporate INEOS by the dealer, but corporate INEOS has declined to cover it under warranty. In response to whether there were any warning lamps, messages, or other symptoms of the problem prior to the failure: No. The crack appeared suddenly on [XXX], while driving at a slow speed.
