Rented a 26 ft diesel truck from Penske and had a terrible experience.
I specifically told them I had never driven a diesel truck and asked for full instructions. They failed to mention something critical: the truck requires DEF (diesel exhaust fluid). When the DEF ran low, the truck lost power on the highway and eventually became undrivable.
I contacted Penske multiple times during the issue — no response.
A roadside mechanic later told me I just needed DEF — something that could have been avoided entirely if Penske had done their job.
On top of that, the truck had multiple mechanical failures (lift gate and engine issues), causing major delays and extra costs.
Then Penske sent me a bill blaming me for the DEF issue — even charging $66 for fluid that costs about $25 in stores.
Poor maintenance, poor communication, and zero accountability.
Would not recommend.
Recommendation: trucks not maintained properly
