Example complaints

“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”
NHTSA complaint #11671395, filed 2025-07“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.”
NHTSA complaint #11602831, filed 2024-07“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. …”
NHTSA complaint #11689392, filed 2025-09, 11,000 miles“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 circumstances 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. …”
NHTSA complaint #11666766, filed 2025-06“The body Control Module has been found faulty in numerous vehicles that affects the power windows, headlights, locks, Air condition, etc. Currently the manufacturer cannot reprogram new replacement module as they do not have a software capability.”
