I have the Bosch Starter for my 3.0, my last replacement from autozone that was 200+ didn’t even last 2 years, Bosch still going strong and I have cheap duratrash as a backup in my tool chest but it’s been collecting dust!!

Pros: long-lasting, reliable

ESPECIALLY with a Honda, go Denso. I had an experience with a failed starter (would only intermittently grab the flywheel) on an '07 Accord where the starter is behind the exhaust manifold. Had a shop replace (they used a Carquest reman) and the issue returned so they replaced again. Off the engine they both tested fine and in spec. Shop refunded the repair as long as I returned the 'faulty' starter so I decided to try but use a reman OEM Denso and it fully worked and has been working flawlessly for years now. It costs a bit more, but worth it - On a Honda at least.

Pros: fully worked, working flawlessly
Cons: failed starter, intermittent grab

Denso OSGR Light Duty starters are very common so parts are easy and any local auto electric rebuilder has seen heaps of them. They may have parts to fix it on the spot. I order a primary gasket/seal kit online because swapping one is a primary cover R&I, and one muliple pack of starter motor to engine case gaskets since they're so inexpensive. If the starter concerned lacks an aftermarket pushbutton end cover I order those for every bike I buy.

First thing I do is remove the three screws holding the solenoid end cover to inspect the contacts which are cheap online. Kits with all the seals and plunger are about 30 bucks shipped so I replace them every starter removal o avoid buying more primary cover gaskets. Then (bike in neutral!) I bottom the exposed plunger manually. If starter rotates but engine does not it's starter clutch time. If engine starts I drill a ~1/4" hole centered on the end cover then reinstall it so I can ride until I sort the parts situation by usung a round shank screwdriver to push the plunger and start the engine. If putting battery voltage to the small blade connector which controls the solenoid does nothing the solenoid windings would likely be open. Those can be replaced from a donor but don't fail often. If I replace a starter I fix the original as backup.

All Balls starter clutches are decent though I don't know the OEM for the or HD. HD outsources starters but dealers stock them and parts.

Pros: parts are easy to find, inexpensive gaskets
Cons: solenoid windings can fail

Our 2018 just caught the whir of death tonight. 60k on the clock. Any suggestions on what brand to replace it with. Bosch and Denso both have options for the car.

As preventive maintenance I replaced my starter with a new remanufactured starter by Bosch, part number SR0822X. Wouldn't start after I moved it from the wash bay to vacuum the inside. I heard a click and that was it. The starter didn't try to turn the engine at all.

Cons: starter didn't turn
Vehicle: Volkswagen Phaeton
Part number: SR0822X
