Selected complaints filed with NHTSA by 1998 Chevrolet Astro owners, lightly cleaned up (personal details are redacted by NHTSA).
I have a 1998 Chevy Astro van that qualifies for a expired warranty for GM that is related to a defect in their fuel injection system that causes them to stick open or closed. I was never notified by Chevy about this problem and was not properly diagnosed by a mechanic until this year. The bulletin/warranty number is: 99066e and it states that all repairs relating to this problem would be covered no charge to the vehicle owner as long as it's within 10 years or 200,000 miles. So, I'm 3 years out of warranty and I have 217,000 miles. It doesn't seem right that Chevy never contacted me about this and I've had to pay for numerous repairs related to the fuel system in this vehicle over the years without that could have been avoided if I had my fuel injection system fixed. These vans are known to run up to 450,000 miles. The operation of my vehicle is vital in this economy. …

Comments: I read where NHTSA has started an investigation into this problem. I have a 1998 Astro AWD pasasenger van with the same symptoms (started at 50,000 miles, currently has 67,000 miles. I pulled the fuse so I at least have brakes at slow speeds. I nearly ran into my garage and am concerned becauase we live near railroad tracks. Have rolled into intersections beacause of this safety problem. ABS engages at slow speed which allows vehicle to keep going (renders to brajes useless) there is a TSB by GM on this shown below. My concern is that this vehicle is not listed in your investigation. This is a serious safety issue. …
Roblems that I have listed are only the icing on the cake.
