Great Replacement Starter – Works Like a Charm!
Model: 10914
I recently replaced the starter in my 2015 Honda CR-V 2.4L, and the UCAREST 10914 Starter has been a fantastic upgrade. The fitment was perfect—it matched the OEM part numbers exactly, and installation was straightforward. It took no time at all to get it in, and once hooked up, the car started up instantly, no hesitation, no grinding sounds. The starter is solid and durable, and after a few weeks of use, I’m still impressed with how well it’s working. I’ve had no issues with it, and it’s performing just like the original one, if not better. The quality seems great, and it gives me peace of mind knowing I have a reliable part under the hood.

Trash
Model: 17785
Ordered 2/22/26, installed2/23/26, had a gritty sound immediately, and should've asked for a replacement then but was just happy to be mobile again, 3/29/26 left me sitting on the side of the road popping starter fuses over and over... not a decent part especially since im now realizing there is zero warranty... do yourself a favor, read the reviews before you buy and dont put money in this sellers pocket
