While driving this cargo van, the driver stopped in traffic to make a left hand turn. In the middle of the turn, the vehicle stalled out and would not immediately start, exposing the vehicle to nearly being hit by the oncoming traffic. When the vehicle eventually restarted, and later brought to a GM dealer for repair, it was discovered that the main ground cable had completely deteriorated. In our fleet of 15 GM vehicles, this is now the SEVENTH vehicle that has needed this main ground cable replaced. This is a serious issue that needs to be addressed.

Catalytic converter cracked at exhaust manifold @5 yrs, 34,600 miles. Known problem, denial, scam warranty allowing them to break ‘clean air act’ and scam customers into paying. On the hook myself for a fed law requiring manufacturers repair. At my shop getting fixed when they offered to fix after my mention of fraud! 3 years of claimed-broken welds in vans (doghouse over motor). I know of 4th year problem. Also not believing bad weld.Engineer friend says stress crack. Weak metal, no support due to flex pipe I believe. Cheap parts, money over safety again. And I have proof they do it and deny, misdiagnose, and lie. Criminal I think. Posting online about warranty scam. I was schooled in auto, small business owner. I know law! Given up on gov I’m sorry to say.

Bought this van new & when traveling down a hill, brake assist helps slow up the van. Once the van is on level ground, it will NOT shift back out of the brake assist & it takes effort or time to return to normal D. I was told I must set up & find a hill. I had major water leaks in the van & once corrected, there started a whistling of air now. The passenger door was 1/4" off, nowhere near flush. How does that get missed? Lastly, the right read brake cylinder went out with less then 12,000 miles on it. Many many problems with this "new" van. I'm concerned for my safely & others. The future looks bad with this lemon.
