jpms95 - If they were installed by dealer at time of initial vehicle purchase, they should be replaced free of charge for 3-yr/36k-miles per TSB A20-022. Let the dealer eat the price & labor of constant replacing low quality part. Perhaps ask if they will 'leave' one of the defective units in your cargo area, so at a later date you may disassemble it and see if you can find aftermarket bulb alternative 🤔
