I have a 2006 corolla, had same problem, just bought a new denso starter and no more troubles. Very easy to put the new one on actually, remove the fan on the front first for more space

Pros: easy to put on

Vehicle: Toyota Corolla

Mine did this, it was the contacts internally in the starter motor, they wear down and make poor contact, I replaced it with a denso branded one, it never missed a beat

Pros: never missed a beat

Cons: poor contact

Finally decided to commit and replace my noisy startup starter with a Denso Reman. No the starter wasn’t dying, I purchased the car already making the noise, and have had it now for 3 years. I was just getting tired of hearing that grind noise when I start the car mostly in the winter.

Pros: quieter startup, no grind noise

This sounds like a cheap Amazon or AutoZone starter was used. Replace it with a Denso or OEM Honda part.

Pros: OEM Honda part

Cons: cheap Amazon starter

Denso starters last forever, it's the motor contacts that die. You can get a set from a Toyota dealer for a massive fraction of the cost of a OEM Reman ( the only way to go if you don't have time).

Pros: starters last forever

Cons: motor contacts die

I ordered a new Denso starter from Amazon for my Honda. It went bad in about 3 months. Fortunately I was beside an auto parts store. I had to buy a new starter to get 100 miles home. The company that I bought the alternator from refused warranty. I had to call Amazon to get a refund.

Cons: failed quickly, warranty issues

Vehicle: Honda
