Why Alternator and starter purchased have so many quality issues?

                                                               By Carl Li,

The average warranty return rate for aftermarket rotating electric is like 3%-4% even for companies put lots of quality activities, this number can be much worse for lots of companies if just buy and sell.

Below are our findings why the return rate is so high and how to improve the situations.

  1. Some products are developed based on aftermarket samples. The manufacturer may leverage existing designs and cause the components not interchangeable with OE, like cosmetic and internal parts.
  2. Some manufacturers cut corners, using less copper, less winding turns, skip heat treatment etc.
  3. Some manufacture doesn’t have OE’s assembly and material specification. Used to work on some issues like not using the right torque, issues caused by wrong insulators (PPS Vs Nylon) etc. Also have some workmanship issues due to no working instruction, operator high turn over etc.
  4. The design of OE is not robust enough, like plastic gear track issue of PG260 starters under certain applications. Lots of plastic gear track cut and some customers in aftermarket reinforce the starter through metal gear track.
  5. Lots of manufactures do performance testing against OE sample, but not all manufactures do the endurance test and thermal cycle test.
  6. Lots of issues are caused by cross reference, some items are over consolidated like pulley type, output, designs ( Valeo, Bosch etc).
  7. The supplier changes his vendor without customer approval due to cost savings.
  8. The quality of key components are not good such as regulator, rectifier, bearing, grease etc.
  9. Poor on trouble shooting and no good process on corrective actions.
  10. Do’t have good quality control and assurance to make sure the quality consistent and with in control even the first article samples pass the qualification.
  11. Parts come back from customers because the installer is ruling out what it might be instead of doing the proper diagnostics, specially from Autopart Chai store customers.

If your volume justified, you can consider to get the alternator, starter do an endurance test periodically based on family and sampling plan. Make sure the manufacture has the right new product development process, control plan, using right bearing, rectifier, regulators. Tear down the warranty returns, analysis by layers like family, customer, applications, drill down the quality issues to get the root cause and implement the corrective actions.

But if your volume is low and in high mix, better you can trade through a reliable agent who knows the product, quality, manufacturer and help you buy from the qualified sources approved by prestigious customers.
