I bought a new car Mazda3 2019, (Under $40,000). 1 week after I got it, someone dinged the back of the car.
I called insurance, and they said I could have it repaired "not at fault" (I have comprehensive RAC insurance if that makes a difference).
When delivering the vehicle to the repairer, everything was working perfectly, the damage was only cosmetic.
The repairer repaired the ding, but kept the car a full week because they needed to order a new rear bumper because there was a crack in the plastic that was not repairable.
After, they had told me that there are further delays as the rear blind spot sensors are malfunctioning (false-positives).
They took it to an auto-electrician who could not repair (as it's a new car and they didn't have the parts), then they took it to the local Mazda dealer. The local Mazda dealer had it for a few days and they ordered new blind-spot sensor controls (telling me it was $3000-$4000 worth of new parts for the 2xblind-spot sensor computers).
More and more delays later, I have it back, but the sensors are still malfunctioning (driver's side false-positives and passenger side not working at all)! The Mazda dealer clearly was not able to test/repair the fault.
It's been at the repair shop longer than I've owned it, they left the windows and doors open, so it doesn't have that new car smell, and they managed to drive it another 300Kms.
Also, the dashcam went missing, but later was found tossed under the seat (not sure how it got there as it was fixed tight!).
I feel like I own a 2nd-hand car, and I'm quite saddened.
Regardless, as the car was in a minor accident, I'm unsure of my rights. At this point, I just want a replacement vehicle.
Any advice?
Update:
Returned the car to the smash repairers who returned it to the local Mazda dealer. They have had it for another week or so. They still couldn't find the fault.
Today, they swapped a bumper today with one of the ones in the yard as a test. Apparently no issues with a new car's test bumper.
I advised during my testing that when a car drives on the left, the right-hand sensor lights up, and when a car drives on the right, nothing happens. Apparently the cables are all connected correctly, though. Now the smash repairer and the dealer are playing the blame game. The dealer says that Mazda was not able to properly diagnose, and has spend 1000s on labor and new sensors. Mazda is blaming the smash repairer saying that the paint is "too thick" on the new bumper. The smash repairer is trying to get information from Mazda Australia on the required paint micron thickness as well as paint spec. They don't have an ETA for me.
My 1 week old car has been at the repairers over a month now! It's surely had a few more 100Kms added to it. I took a look at the car, and it has some new minor scratches on it which the repairer said they will fix. I've filed an enquiry with the ACCC to see if there's something they can do. More advice would be appreciated.
