I recently had my windshield broken on a cross country trip. When I got home, I had the windshield replaced at the Land Rover dealer with factory glass. Within a day or two of having that done, the dashboard would light up with all sorts of messages and warnings. Very often the car will go into a limp mode, lower the suspension, and limit speed. I tried to post a video of the dashboard when this happens, but this site won't seem to allow it. I took the car to a reputable indy and they recommended a battery and alternator replacement based on the fact that the battery was over 4 years old and there was an error message for the generator(error report attached). I have now had the car at two independent Land Rover shops and no one can find the issue. The errors are all related to the high speed CAN BUS. After the alternator was replaced, the message related to the generator has gone away but the car still freaks out at least once a week. If I disconnect the battery leads and connect a wire between the leads for a few seconds, reattach the leads to the battery and wait for a bit, it usually clears the dash with the exception of the check engine light. The check engine light will usually clear after a couple times of starting and stopping the car. It happens at completely random times. Sometimes it is shortly after starting and sometimes it happens after driving 100 or more miles.
Based on the fact that this started almost immediately after the windshield was replaced, I was wondering if anyone knew if there was any wiring in the A pillars, under the lower windshield cowling, or where the mirror connects to the windshield that could be causing a problem with the High Speed CAN BUS. I am hesitant to go back to the dealer until I know more as I'm sure they will try to deny any responsibility.
Any information/guidance would be greatly appreciated. I love the car but if I can't get this figured out, I think I'll need to trade it in...
It is a 2015 LR4 HSE and has approximately 68000 miles. After the windshield replacement at the dealer, I had the following maintenance items performed
Front and Rear Crossover pipes
Thermostat
Water Pump
Battery/Alternator
