GM Releases 15-Passenger Safety Video
GM Released this video to highlight Stabilitrac, the electronic stability control feature in their new Chevrolet Express and GMC Savannah 12 and 15-passenger vans.
The video also talks about NHTSA’s recommendation to use seat belts, claiming that it will increase your chance of survival by 70% in a rollover situation.
Mark’s Analysis:
- The biggest improvement with the GM 15-passenger vans is the lengthened wheel base. It is substantially longer than the Ford E350 or the Dodge Vans.
- The electronic stabilizer system is a much needed add-on feature. Over the years, the onboard computers that control these stabilizers gets smarter, and hopefully, prevents accidents.
- Ford also added an electronic stabilizer system to its van. Unfortunately, the van’s wheel base is still too short and the left rear tire still has 45% of the weight on it. In the event of a tire de-tread, an electronic stabilizer will have minimal value, especially if the rim is exposed and the rim digs into the pavement, launching the vehicle into a rollover condition.
Why do 15-passenger vans roll over?
Andrew Smith created this video explaining why 15-passenger vans rollover.
Bottom Line: 90% of the rollovers are caused by a left-rear tire de-tread.
Details discussed in this video:
- There is a design flaw in the Ford E-350 (Econoline XLT), that places 45% of the weight on the left rear tire.
- The aisle on the right side of the van contributes greatly to the weight being placed on the left side of the van
- The E-350 requires 50 psi on the front tires and 80 psi on the rear tires. This is the only vehicle on the road requiring different pressures on the front and rear tires.
- The increase weight on the left-rear tire generates excess heat inside the tire.
- If the tire pressure is lower than manufactured specs, this will significantly increase heat inside the tire.
- Once the heat generated inside the tire exceeds the manufacturers specs, the tire will de-laminate, causing the tire to de-tread.

Churches and Missions groups keep vans in spite of dangers
While 15-seater vans are illegal to sell to public schools, they are being sold to private schools, day-care centers, senior centers, churches, missionary groups, etc. In 2005, I received a phone call from the head of the National Transportation Safety Board (NTSB). The NTSB is an independent agency that investigates accidents (air, sea, train, motor vehicle) and make recommendations to NHTSA, Federal and state governement agencies. The director thanked me for the Van Angels website and encouraged me to continue to educate the Christian ministries about the dangers of the vans.
The director went on to explain his frustration with the 15-passenger vans. In the past few years, the NTSB has investigated three (3) separate 15-passenger van rollover accidents and made recommendations in all three cases. These recommendations include:
Read the entire NTSB report and their recommendations to NHTSA:
NTSB Safety Report: Evaluation of the Rollover Propensity of 15-passenger Vans (PDF)
According to an NTSB spokesman, about 80% of all NTSB recommendations are adopted by state & federal agencies, including National Highway Transportation and Safety Administration (NHTSA). Yet, as of today, NONE OF THE ABOVE NTSB RECOMMENDATIONS FOR 15-PASSENGER VANS HAS BEEN IMPLEMENTED. Ironically, many of these recommendations have found their strongest opposition by the Christian Educators Assocation. In short, Christian schools, churches and missions groups have lobbied government officials to ignore the NTSB’s recommendations. They site various reasons for wanting their organizations to be able buy and use 15-passenger vans in spite of the known dangers.
Why would a Christian private school want to transport their kids in a van that has been outlawed by virtually every state in transporting public school children?
Here are some reasons why churches, private schools and missions groups continue to use the van in spite of the known dangers:
BOTTOM LINE: Many small organizations believe the “advantages” above outweigh the potential dangers. Many have not done any sophisticated analysis of the issues, they just hope nothing bad will happen.
