I work for a Nissan dealership as a vehicle technician and I look after the high performance vehicles (GTR’s, 370Z) and about 13 years ago we fitted a set of front parking sensors to a Nismo 370Z and they didn’t work properly for some reason, these were Nissan branded sensors and we had fitted them on many other vehicles with no issues. After a while replacing the control unit and the sensors they still refused to work correctly so we got in touch with Nissan technical support and found out from them that they don’t work on the 370Z’s and the GTRS so please don’t fit them. We had to replace the front bumper of the Nismo 370Z and take the expensive lesson on the chin. A few months later we sold a new GTR to a to put it mildly an aggressive customer that had to have things his way and we were definitely perceived as the lower class. He wanted front parking sensors fitted to his new car and the salesman let the order through to us. The sting of what had happened before was still there and we told the salesman straight away that it’s not a good idea and tell the customer that they will not work. The customer knowing everything stated that they will work and there’s no reason why they shouldn’t he’s had them on previous vehicles and wants them fitted and at a reduced price for the stress we caused telling him he can’t have what he wants. So it fit them, they don’t work great but do to a degree and we tell the customer that we warned him they wouldn’t. He took the car away and was back in a couple of days saying it’s unacceptable and we need to get them working correctly or he will cause a big stink on social media and get his lawyer involved! So we spend a week tinkering with the car and no joy, they just wouldn’t work right by now he’s ringing in everyday to see if they are fixed, we would say sorry sir as we were told by Nissan and passed that information on to you they won’t work on your vehicle you were advised strongly not to have them. So he wants them removed and to fit them you need to put holes in the very expensive bumper. Obviously he isn’t happy with the 4 holes in the front of his car and demands a new bumper from us. Luckily all calls are recorded at our dealership and we had him on call requesting sensors to be fitted despite our advice, we refused to replace it for free, he stormed off threatening lawsuits. A few weeks later it’s back for a new expensive bumper at his cost.
