| Steering problems |
Brand new delivery there was a noise that changes with engine rpm. It also changed with turning the steering wheel. The dealer diagnosed a bad power steering pump. Due to possible metallic contamination all related parts that are connected to the power steering pump including the hydroboost brake assist are going to be replaced.
I recently purchased my vehicle from big star dealership in baytown TX. At a little over 1000 miles I was towing a camper. The vehicle stalled, fuel pouring from engine. It was towed and repaired due to fuel pump failure. At a little over 3000 miles the vehicle would not start. Dealership initially said water contamination then changed it and said gasoline contamination and now they say def contamination. The vehicle stalling the first time almost caused me to wreck the vehicle.
Ongoing issues with steering pull to right, and brake pull to hard right when applying brakes, which also turns steering wheel to right upon application. Have to keep steering wheel towards left with constant pressure to go in straight line and when braking. Driver has to be aware of changing road conditions that could affect that. Multiple inspections at multiple dealers have found no obvious issues, and multiple alignments performed, with tires also being replaced have had no success in correcting issue. Front suspension starting to feel loose due, and rear suspension squeak when going over bumps. Also recently found rear axle is shifted slightly to right. Suspect all are related. No parts replaced to date other than the tires. Happens daily. No accidents to date. Daily driver with long trips at times. Steering pull issue has present since new but everything else has occurred since about 1800 miles and has progressively become worse. Conditions becomes worse at highway/freeway speeds of 65 to 80, but occurs as low as 10mph. Going back to 3rd dealer to look at it again. Truck is 2026 with 10,583 miles.
