Problems with 2006 Chevrolet Uplander ENGINE AND ENGINE COOLING

1st the check engine light keeps coming on and when put on diagnostic code came back po463. the van wouldn't pass emissions and when you fill up with gas it would say it was empty. there's a loud popping noise sounds like at axle. it does this after you stop at red lights. i was told this had to do with axle and could brake and cause fatal accident, the abs light keeps coming on and the braking system scared me to death. the doors constantly chime or ding and the doors will open going down the road. i was so upset because i have to transport my elderly aunt and two children and before i was about to pay to have all this fixed i decided to check out recall. i am so shocked that you can look this up online and they are 1000 documented complaints on all the same problems but yet no recalls. is it going to take people getting killed to do this. i am praying for something less tragic and trying to save these precious lives. there is research and lawsuits that the chevrolet uplanders have a lot of these problems from 2005 to 2008 especially with the doors and like me everyone gets annoyed and unplugs them and have to use them manually but why should we when are still paying for automatic doors. this van is truly unsafe and a lemon. i pray to god everyday to keep me safe while driving and have told my husband if i die while driving this vehicle he should sue!!! updated 01/17/12 *bf the consumer stated gm called and asked her to bring the van in for a diagnostic test. they stated she would have to pay for the test. the fuel sensor was replaced in 2006. however, the consumer stated it had to be replaced again. they also aligned the doors in 2008 which was proof of an ongoing problem. updated 01/18/12 *tr
