I love my ‘24 Big Bend. Bought it off the lot with 28 miles and has been my daily driver for 2 years. Racked up 50K miles pretty fast and I get oil changes every 5K. One had one issue and needed my Water Pump replaced after leaking all my coolant and wasn’t getting heat. Was covered under warranty and didn’t have to pay anything.

Pros: daily driver, covered warranty

Cons: water pump replaced, coolant leak

Vehicle: Ford Bronco

Mileage: 80467 km

'22 OBX has treated me well enough aside from the recalls and water pump. A beast in my rural Canadian snow, and feel like a tank on the road.

Pros: beast in snow, feels like tank

Cons: recalls, water pump

Vehicle: Ford Bronco

The Aisin kits are fine. I would not use a gates kit; the water pumps are junk and so are the tensioners

Pros: Aisin kits are fine

Cons: water pumps are junk

I want to share a brief but critical report regarding the recent replacement of the engine's electric water pump (EWP) on my Prius Gen 4. The analysis of the data logs revealed an alarming scenario; the new aftermarket pump's performance was completely unreliable, showing clear evidence of torque failure and instability. I had no choice but to purchase the Original Equipment Manufacturer (OEM) pump from the dealership (it was stamped with the AISIN logo). The problem was instantly and definitively solved.

Pros: problem instantly solved

Cons: unreliable performance, torque failure

Vehicle: Toyota Prius
