Door May Fail to Latch and Open Unexpectedly
An unlatched door can open unexpectedly while the vehicle is in motion, increasing the risk of injury.
NHTSA Campaign Number: 25V147000
Manufacturer Ineos Automotive Americas, LLC
Components STRUCTURE
Potential Number of Units Affected 7,022
Summary
Ineos Automotive Americas, LLC (Ineos) is recalling certain 2024 Grenadier vehicles. The door button mechanism may have been assembled without a sufficient application of grease, preventing the door from fully latching.
Remedy
Ineos will replace the door button assemblies, free of charge. Owner notification letters are expected to be mailed March 31, 2025 through May 4, 2025. Owners may contact Ineos customer service at 1-833-494-4748.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 888-327-4236 (TTY 888-275-9171) or go to nhtsa.gov.
Beginning in October 2023, INEOS became aware of a number of warranty claims for exterior door
buttons sticking when being opened from the outside. INEOS initiated a review along with its
supplier to attempt to better understand the issue. During the course of that review, the supplier
identified a process change at its facility that led to an inadequate amount of grease being applied
to some areas of the door button mechanism. Based on this information, an interim containment
action was initiated to rework vehicles remaining in INEOS’ facility. INEOS also requested its
supplier to review the door button kinematics to see how operation of the mechanism could be
improved for future model years. Following the rework of vehicles at its facility, INEOS issued a
technical service bulletin to dealers on February 15th, 2024 with instructions to re-grease the
component mechanism.
Between February 2024 and June 2024, INEOS received two reports of doors opening while driving
on U.S. cars. There have been no reports of the driver’s door opening while driving. INEOS
conducted further analysis of the issue, including an analysis of warnings to the driver and vehicle
occupants if one or more vehicle doors did not fully close. Based on that analysis, INEOS
reasonably believed that there was sufficient advanced warning to vehicle occupants if the door
was not fully closed and none of the warranty claims or VOQs to NHTSA at that time described that
the vehicle was not receiving in-vehicle warnings (visual and audible) in addition to the status of the
door being observable to the user. Based on the field data and analysis at the time, INEOS
reasonably believed the risk caused by sticking door buttons (including the risk of doors opening)
was low and continued with its effort to re-grease doors experiencing the condition. (continued
below)
(continued from above) As of late January 2025, INEOS became aware of a second VOQ to NHTSA
describing a door opening while the vehicle was in motion. INEOS responded to questions from
NHTSA about the VOQs and the issue more generally. On March 4th 2025, INEOS determined a
safety related defect exists in the subject vehicles and decided to conduct a recall to address the
defect. As of the end of February 2025, INEOS is aware of 4 VOQs potentially related to this issue.
There have been no reports of injury.
After verifying the VIN population and remedial component validation, INEOS decided to issue a
notice of defect to NHTSA on March 6th 2025 to replace door button mechanisms in all vehicles
manufactured before April 19th 2024
Background
INEOS has identified a safety related defect relating to door button mechanisms affecting
vehicles covered by this notice. In a proportion of affected vehicles, the door button
mechanism may have been assembled without a sufficient application of grease. This may
allow the exterior door buttons to remain in the depressed position and prevent the door from
fully latching.
If the door does not latch, it may open while the vehicle is in motion, increasing the risk of
injury to passengers inside the vehicle.
Vehicles Affected
Vehicles within dealer inventory within the following group:
INEOS Grenadier Station Wagon MY24
VIN range: SC6GM1CA0PF004877- SC6GM1CA5RF018955
Affected vehicles will be notified to dealers by way of VIN lists applicable to the relevant dealer.
Stop Delivery Notification
It is a violation of federal law for any new motor vehicle covered by this notification to be sold,
leased or delivered until the recall repair set out in this document has been performed. This
means that dealers may not legally deliver new motor vehicles to customers until they are
remedied and cannot use or sell as replacement parts, the components which are subject to
this recall. Substantial civil penalties may apply to violations of the federal law.
Please follow any special instructions that we provide to you for the return or disposition of
recalled parts and components.
Next Steps/Notes
Customers may continue to drive cars, and demonstrator vehicles may continue to be used,
provided that care is taken to:
observe that door buttons have not stuck when pressed,
ensure that all doors have been fully closed and latched,
check on the vehicle head unit that there are no indications or warning signs that one
or more doors may not be fully closed;
obey all audible and visual warnings if a door is not fully shut.
INEOS will separately provide detailed work instructions to all dealers as soon as possible.
INEOS will notify customers with affected vehicles of the recall by letter and other means.
An unlatched door can open unexpectedly while the vehicle is in motion, increasing the risk of injury.
