Hello everyone,
I have owned my 13 maxima since 2013. I just recently started having an issue with the ABS sensor in the past few years. I've replaced all of my wheel hub assemblies, shocks and struts within the last 2 years. I had my ABS light come on in November of 2017. I went to a shop and they told me the right rear sensor was bad. I ordered a sensor from advance that was supposed to be an exact fit but it didnt I had to order another and it worked and they replaced my wheel hub assembly with a Moog. In August 18 I had the ABS light come on again and it was the right rear. They replaced the sensor again and another Moog wheel hub. We're now in February 19 and the light is on again for the same sensor. I took it to the shop and they just replaced the sensor and it worked for about 75 miles. I took the car back to the shop and they told me they didnt replace the hub this time. They ordered a Beck Arnley this time and the right rear started to make a grinding sound at 50 mph. They're saying it was a bad wheel hub assembly. They're trying to replace it with another. I am seeing if anyone else had a similar issue. Thankfully everything was still under warranty and I didnt have to pay for anything but if this doesnt work I think I might have to go to the dealership. I hope someone can give me some advice.
