Here is what Proton has to say regarding the X70 incident, so there is no need to speculate
Proton would like to issue the following statement with regards to a video currently circulating depicting a thermal incident on a new Proton X70. We are aware of the incident and would like to thank concerned parties for sharing the information.
The vehicle is now in our possession and was not registered at the time of the occurrence. Proton engineers have started the investigation process while working closely with the relevant authorities. An update will be issued once all the information has been obtained.
Meanwhile, we would like to reassure all customers that Proton vehicles are developed to meet the highest standards with each unit undergoing stringent quality and safety inspections prior to being delivered.
The Proton X70 was awarded a 5-star ASEAN NCAP rating when it was tested in October 2018 and with nearly 100,000 units produce over the past five years, it is the most popular model in its class during that time period.
