“I own a 2001 Isuzu Trooper that started using excessive oil (1+ quarts every 1000 miles) at 54,000 miles. I have found numerous complaints about this starting when Isuzu introduced the 3.5l v6 engine. My research has shown the problem to be a bad design change of the oil ring not allowing oil to drain properly. Isuzu is terrible to work with and fights to not honor warranties. Why has this not been investigated by NHTSA after all the complaints received about this problem? Isuzu has terrible customer relations and does not stand behind their vehicles when there is a problem. …”

“My SUV , Isuzu Trooper of 10years, was parked in a library parking garage and after ignition turned on, I put it in reverse gear to get out of the parking lot and the car rapidly reversed and before I could figure out and react, the car shot like a rocket towards the front , while still in reverse gear, and I had no control of the brakes or steering wheel, it rammed into a concrete pillar and got completely totaled. Airbags opened and front doors jammed and I had slide to the back to escape. Luckily, car did not catch on fire or explode. …”
