Does not install to safety standards in Toyota Sienna
I purchased two Pioneer seats for my kids; these were my 3rd and 4th Britax car seats respectively. I read reviews (not from this site, but from other parenting review sites) prior to purchasing this model that said this model is comparable to the Frontier as long as you don't mind taking extra time to ensure proper installation. Given the price difference between the Pioneer and the Frontier, I decided to try this model. With any car seat, I meticulously read the manual so I can ensure proper seat adjustment and installation in our cars. I did the same here. Given my kids' weight, I chose to forego the LATCH installation and instead use the lap shoulder belt. No matter how tight I pulled the belt, no matter how much I pushed the car seat down with my own weight, I could not get the Pioneer to tighten enough to move less than the recommended 1". In fact, the seat was moving more like 6-8" in either direction after attempting to tighten. Thinking it must be user error, I looked up install videos and even called Britax directly. Ultimately, the only advice the service agent was able to give me was to find a local certified car seat technician who *might* be able to help me. If this was the kind of hassle I would have to go through every time I needed to remove/reinstall the Pioneer, no thank you. After almost an hour trying to install this seat - and still not being able to do so safely - I returned both Pioneer models. Not worth the headache or the lack of peace of mind that my seats were not installed safely. I have since purchased the Frontier with ClickTight model (2 of them) and while significantly more expensive, the Frontier installed safely in my van in a matter of minutes.
