Jason drafted Daubert motions and a motion for summary judgment on behalf of a major automobile manufacturer in the U.S. District Court, Southern District of Iowa. He successfully argued to the court that the opinions of plaintiff's fire-cause-and-origin expert and mechanical engineering expert were unreliable and insufficient to support plaintiff's strict liability, negligence, and breach of warranty claims. As a result, the court limited the testimony of plaintiff's proffered experts and granted the manufacturer's motion for summary judgment.

In an unpublished opinion, the Iowa Court of Appeals affirmed the trial court's directed verdict ruling in favor a major automobile manufacturer. Jason drafted the manufacturer's appellate brief and represented it at oral argument.

Jason second chaired a product-liability case on behalf of a major automobile manufacturer in the 16th Circuit Court of Jackson County, Missouri. Plaintiffs sought to recover for the loss of their home and contents after a fire originated in the engine compartment of their vehicle. Plaintiffs claimed the fire was caused by a defective alternator. Jason deposed plaintiff's key liability expert witnesses. At trial, he cross examined several expert witnesses. In closing, plaintiffs' counsel asked the jury to award $3.2 million for plaintiffs' lost property and punitive damages. The jury returned a plaintiffs' verdict for $350,000, but it did not award any punitive damages.

Jason second chaired a product-liability case against a major automobile manufacturer in the District Court in and for Black Hawk County, Iowa.

In the pre-trial hearing, the court granted the manufacturer's motion. After plaintiff rested his case, the court granted a directed verdict in favor of the manufacturer because without plaintiff's expert's excluded testimony the plaintiff did not have any evidence to support his claims that the vehicle was defective.
