2024 Ineos Grenadier Recalls & Complaints

Incident: September 18, 2026 · Filed: October 27, 2026

At approximately 28k miles my dealer, during routine maintenance, noticed the front driveshaft boot had torn and was weeping grease. They replaced this driveshaft under warranty (5 year, 60k miles). Fast forward to 114k miles and after a throttle body failure and requesting an oil change the dealer noticed that the front driveshaft boot had torn and all the grease was out with some rust present. This time the manufacturer would not honor any warranty claim due to exceeding the mileage. Much of my driving is highway and I would have to say that the boot for the driveshaft is not designed appropriately for the application. This is a known issue with the vehicle and any dealer is aware to look for this issue. My vehicle is not modified in any way to affect the driveshaft. Should the driveshaft fail while driving at highway speeds could result in serious injury to the occupants but also other vehicles that may be nearby.

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.

HVAC system is erratic and can blow VERY hot air when set to cool, so hot that it burned the top of my feet while driving and forced me to exit the freeway and shut the vehicle down. This failure is random, and properly written fault-tolerant software should NOT allow this condition to happen; it would be better to shut the system off than to cause blisters on people's feet or blowing 140+ deg air when it is only 110° outside. Also, the HVAC system, when malfunctioning, cannot be turned off... it continues to blow hot air. I have taken it to the dealer 3 times with no HVAC resolution, and have been waiting for Ineos to provide a solution.

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.

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.

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.

There appears to be some electrical malfunction that causes the air conditioning to produce exceptionally hot air. It can only end when the air conditioning system is turned all the way off. This is a known problem in the owners groups that many people are experiencing. One of my friends just measured the temperature at 192° blowing out during air conditioning setting. I am having something similar And this must be fixed as it is dangerous
