“I have been having issues with my azrek shutting off on me in the middle of driving and now it wint even start. I have replaced the fuel pump and vapor sensor due to it not getting any fuel pressure. I have researched and there are 2 different recalls for my vehicle which have not been done due to my VIN not being acnowleged with the recall”
NHTSA complaint #11067057, filed 2018-02, 153,000 miles“I recently borrowed my mother-in-law's vehicle. When I returned to my home I parked in the attached garage. Later, when my daughter came home she asked why it smelled like gas. I went to check and upon entering the laundry area (directly attached to the garage via access to the house) I noticed the smell. I inspected the garage and thought, perhaps, the smell was coming from a weed wacker. Later, I went to check on some laundry and the gas smell was even worse. …”
