Delivery Fuel Pump problem #1

I purchased a brand new fuel pump on 2-28-24 after car died on freeway. Mission hills Hyundai diagnosed as pump not turning on, so recommended replacing fuel pump assembly. On [xxx] car wouldn’t start, so took vehicle in and the next day it was determined as faulty starter. Car was picked up 7-3-25 after buying a new starter, but car would not start again the next day. The car was actually misdiagnosed and the ruling was tank fuel pump had an intermittent short circuit. I’ve driven on the fuel pump I purchased on 2-28-24 for about a year in a half. It only lasted 40,000 miles. Fuel pumps last 100,000 to 200,000 miles. I’ve driven other vehicles going over 100,000 miles on the same fuel pump. How did this fuel pump go out so quick? was it installed right? was it bad wiring? was it a defective part? thankfully the fuel pump went out when I wasn’t driving. This is a major safety issue and lithia, who is the parent company of mission hills Hyundai, should be looked into. Also the misdiagnosis from the technician should be in question to. Integrity is also an issue here, so how can I feel safe if I want to to continue getting my car serviced here. Yes they gave me a new fuel pump with no charge, but still had to pay for a starter I didn’t need. Basically I spent $3000 for a part that went out on my vehicle in over a year. Just like how Ford has a recent recall of fuel pumps, Hyundai should be checked into this issue also. I will attach invoices including a service for my fuel system cleaning. I thought all this work I got done would prevent a major failure on a vital vehicle component. Thank you, hope to hear from you information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
