7-21-23 Unit stalled 3 times today. The last time was while driving. Check engine light on. 1-29-24 Today I was responding to an emergency backup for an officer that was fighting two subjects. The subjects were fleeing from a stolen vehicle and it was dispatched that these subjects were armed. I never made it to this call because my vehicle #10688 would not accelerate past 23mph and then shut off leaving me stranded in the roadway. While waiting for a tow truck I was able to get the vehicle started again and was able to drive at only 36mph to try to get to the scene and assist the officer. I ultimately was able to make it to the police station. I wrote up the vehicle and left the keys in the training building.

The repeated failure of the fuel pumps, despite replacement three times, poses a significant safety concern as the vehicle may not start immediately, potentially leading to issues while on the road. This delay in starting could result in the vehicle not running properly, potentially shutting off unexpectedly, which poses a danger to the safety of the driver and others on the road. Additionally, the uncertainty surrounding the effects of using E85 fuel, despite the vehicle being sold as flex fuel, raises concerns about the long-term viability of the motor and overall vehicle performance. It's imperative to address this issue promptly to ensure the safety of all road users and preserve the longevity of the vehicle's components.
