“In Florida, I purchased my 2004 Isuzu Rodeo March 2005 at 134 miles. I've always had issues, but didn't know how to articulate the issues. My truck sits/leans to the right and low in the back. It is uneven as if the shocks or struts are off. Driving one night, the truck slams down/drops low out of no where while driving. When I am driving and need to brake, I have to brake then brake again. I dare not make any sharp turns by parking or anything it's like the truck will slip or axels bend. I am have trouble with the engine currently(September 2022). Oil is leaking but you can't see from where. The engine is making loud rambling sounds. The exhaust sounds muffled. My car parts are not exact because my Rodeo is built like a demo, seemingly. Power Reduced & check engine light happens randomly usually while on the expressway. It slows the vehicle down in the middle of flowing traffic. I have to try to pull over turn car off then back on to try & reset the vehicle. The car now vibrates but don't know from where or cause. How can I get my car repaired?”
