problem #4

  • 70,000 miles


For the last 2 years I have been trying to get our headlights to work properly with no success. Even when both dim headlights are working they are so dimm we can't drive with them and if one of them goes out we might as well not have a headlight. I have a VW and if one of it's low beam lights is out it is 100 times brighter than the Mazda with both low beams. This is very dangerous because if we are out at night we have to use the high beams which blinds on coming traffic. I have taken it to jim ellis Mazda twice and the first time I didn't even get home with out the light falling out. Took it back and they assured me if was fixed but it wasn't and now the service rep nor the service manager will even return my call. I have had it to 3 different local shops and they can't fix it either. One of them finally got the light from falling out and replaced them both with the brighest light we could find and they are still very very dimm. I have also spent hundreds of dollars on this issue so it is not only dangerous but very disappointing not to mention very dangerous. Thanks, patrick foley

The head lights and tail lights have been replaced over three times in least than two years. The condensation on the covers makes it difficult seeing where one is driving. This I believe is a safety issue. This condensation has also caused my radio to lose its sound. The battery will not start if it rains or its cold.

Purchased vehicle on 2/27/2011. 1) Dec 27 2011 replaced drivers headlamp. 2) 4/18/12 battery issue. Car would need jump starts randomly 3) 8/18/12 passenger headlamp replaced 4) 11/5/12 battery replaced 5) 12/21/12 drivers headlamp replaced 6) 7/1/13 drivers headlamp replaced. Went to 2 different dealers to replace items. Both dealers assured me there is nothing wrong with electrical and it was just one of those things. Unfortunately 4 headlamps and a battery within 2 years of owning the vehicle is just right.
