There are 1 owner-reported body & structure complaints for the 2023 MINI Cooperin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The problem/issue is with THE GLASS ON MY CAR ROOF/THE PANORAMIC SUNROOF. No insulation to protect me/others from heat or cold. The temp of roof gets 2-3 times the temp of the day. 200-300F. This can lead to discomfort/use of EXTRA energy/pollution etc. A child left in such car wd be in deadly danger. The car maker does not want to know or do anything about it. My Mini is not the only car. Almost all have the same design flaw, Tesla is the worst case with full glass roof no insulation at all, KEY PROBLEM/ISSIE Car makers hv remover insulation from car roofs and replaced it with glass but did not replace the insulation. Some as Tesla have nothing others just a simple net-like material with no insulation properties. Detailed analysis with proof attached. This is HUGE problem/issue/flaw that has serious consequences. I titled my analysis THE DARK SIDE OF GLASS ON OUR CARS,. Millions of these cars (Tesla esp over 2 M) are wasting 100s of Ms worth of energy both electric and fossil. Also contribute to additional environmental impact, for the wasted energy has to be made and then wasted by car engines to compensate for lack of insulation in car roofs. No house/homes wd be allowed to be built without insulation in attic/roof etc. So why are car makers allowed to do it with cars. Maybe the govt is not even aware of this. It is possible removing insulation from car roofs is illegal and/or against industry standards. The car makers did it and no one watched them. Many car owners think this is normal. It is not and should be stopped. Please look into this important issue. More details and proof in my analysis. Thank you. ps; I found solution for my car as shown on picture. I could not attach my analysis It is most important I send it to you. Pls send me an email where I can send it. The pictures show the roofs with no insulation and MINI with my solution for heat prevention.
