The contact owns a 2021 Jayco Redhawk. The contact stated that while inspecting underneath the RV the plumbing hoses and lines as well electrical wires, fuel line from the propane tank, and fuel line from the generator was just lying on the frame. The hoses and lines were not insulated or secured underneath the RV. The contact stated that he was concerned that a fire could have been started. The contact stated that he wire-tied all the wires, so they were not laying on the frame. The vehicle was taken to the dealer who only secured the wires with a single wire tie. The contact stated that many of the wires were still just hanging as the dealer did not repair the problem. The contact stated that the brake, fuel, and electrical harness were all clamped together which could cause a failure. The Jayco dealer advised the contact to take the vehicle to a GM dealer for repairs to the chassis. The contact stated he contacted McGee Chevrolet (1455 New State Hwy, Raynham, MA 02767) and they stated they could not repair the RV due to the large size. The contact stated that the Jayco manufacturer was notified and advised to take the RV to a Jayco dealer for repairs. The failure mileage was approximately 1,000.

While driving this cargo van, the driver stopped in traffic to make a left hand turn. In the middle of the turn, the vehicle stalled out and would not immediately start, exposing the vehicle to nearly being hit by the oncoming traffic. When the vehicle eventually restarted, and later brought to a GM dealer for repair, it was discovered that the main ground cable had completely deteriorated. In our fleet of 15 GM vehicles, this is now the SEVENTH vehicle that has needed this main ground cable replaced. This is a serious issue that needs to be addressed.

SERVICE BRAKES
2 Reports11% of totalPreviewing the first 2 complaint summaries.
Bought this van new & when traveling down a hill, brake assist helps slow up the van. Once the van is on level ground, it will NOT shift back out of the brake assist & it takes effort or time to return to normal D. I was told I must set up & find a hill. I had major water leaks in the van & once corrected, there started a whistling of air now. The passenger door was 1/4" off, nowhere near flush. How does that get missed? Lastly, the right read brake cylinder went out with less then 12,000 miles on it. Many many problems with this "new" van. I'm concerned for my safely & others. The future looks bad with this lemon.

After purchasing a used vehicle 2020 model, and after setting in owner's garage for two weeks, the vehicle was driven at slow speed thru two intersections after a complete stop. at the third intersection stopsign the vehicle started moving slowly with the brake on. the brake was then applied much harder very forcefully to avoid a collision. the vehicle continued moving at a creep striking the rear of the vehicle that was passing thru the intersection. the vehicle then continued on..with the brake pedal still applied at floor level and only stopping after hitting the ditch. Problem was----BRAKE PEDAL GOING TO FLOOR AND NOT STOPPING VEHICLE.

Door latches on the side rear door need replaced every few months. Dealer charges $1300 to fix this issue on 8 of the 2020 Chevy Expresses that I we own.

Catalytic converter cracked at exhaust manifold @5 yrs, 34,600 miles. Known problem, denial, scam warranty allowing them to break âclean air actâ and scam customers into paying. On the hook myself for a fed law requiring manufacturers repair. At my shop getting fixed when they offered to fix after my mention of fraud! 3 years of claimed-broken welds in vans (doghouse over motor). I know of 4th year problem. Also not believing bad weld.Engineer friend says stress crack. Weak metal, no support due to flex pipe I believe. Cheap parts, money over safety again. And I have proof they do it and deny, misdiagnose, and lie. Criminal I think. Posting online about warranty scam. I was schooled in auto, small business owner. I know law! Given up on gov Iâm sorry to say.
