I have a 2021 jeep wrangler and the brake hose went on the driver front side. Mopar product ID is 68307451AH. I have called numerous dealerships and Mopar themselves. They informed me this hose is on backorder for over 841 jeeps, and they are unable to get this across the US. Knowing how many jeeps are needing this hose, is it possible to get a recall on it due to the fact it is imperative to fix right away? I've been trying to find a replacement or an alternate but no luck. This is my only mode of transportation and don't want to keep driving my jeep as it continues to veer to the right due to the faulty hose I'm experiencing.
Received regenerative braking must be serviced notice, followed by loss of motive control. Push accelerator, would not accelerate and actually rolled backwards, multiple notification lights came on, car started to move after 5 seconds, happened again. pulled over to turn on/off car, car would NOT turn on. tried several times and resolved to get it towed. After 5 min, tried one more time to start the car and it did turn on. Functioned normally. Drove to dealership and dealership diagnosis is nothing wrong, dealership now working with Chevrolet engineers.
Right real axel seal went bad at 26000 miles.
I was casually driving home from work in a 35 MPH zone on a standard road. When my 2021 jeep wranglers 4xe (30,000 miles exactly) ABS, and electronic brake stabilizer warning lights came on. I touched the brake and they were non-responsive. I then continued to press the brakes all the way to the floor multiple times and there was no response. I was able to pull the emergency brake to bring the vehicle to an immediate halt in the middle of the road and have a tow truck come ASAP. Service the next day said all the warning lights are gone and that they do not see any history of the errors. This issue posed extreme risk for myself and my pregnant wife. The car is still at the service specialist as i requested additional diagnosis be performed.
