Bosch gas stoves/ovens are ****

I bought a Bosch gas stove/oven. Around Jan/feb 2022. Since we had it we battled to get grill function to work. Then just before the one year warranty expired. 2 of the stove plates stopped staying lit. Logged a call and a technician came out to fix it. He removed 2 small tabs from the plate used for the oven. Now the griller works but it is tricky keeping it in place and lit when opening the oven. The 2 plate that were repaired, worked for about a month. And don't stay lit again.
