O2 sensors give out after three months after install and you have to replaced the catalytic converter. Every time the check engine light comes on I have done this process four times. I should get refunded after this because the dealer quotes me $3000 just for parts and not including Labor and that's $65 an hour for a so called 6.5 job. I do it in two hours. So I think these issues with minivans in general are not a bad vehicle it is poor manufacture labor cost that is passed through the line to showroom floor because of cutting costs for the market hurts us consumers in the long run. And the locks work on their own. If it gets hot from the sun they will not unlock by remote or driver side switch.
