I was told it will be 6 k to replace both harnesses. It’s been 8 months and they just received the part. The service tech told me that these cars have this issue due to the position of the harnesses being to close to the exhaust. It dries out the wiring.

Throughout the course of my ownership the vehicle has had multiple sets of tires replaced due to them either being prematurely bald, developing multiple bubbles, or shredding due to cracked rims. Along with the tires being constantly replaced, I have had to replace 8 rims that have cracked under normal driving https://plaincars.com/make/mercedes-benz-cls-450 https://plaincars.com/make/mercedes-benz-cls-450#complaint-1939530 Mon, 30 Oct 2023 00:00:00 GMT I have had to replace 3 wheels at great cost due to cracks. I believe the wheels are defectively designed. The wheels cannot support the vehicle's weight. The cast iron aluminum wheels together with the low profile run flat tires contribute to a road hazard and dangerous condition. I understand that this problem has been encountered by many, many MBZ owners. https://plaincars.com/make/mercedes-benz-cls-450 https://plaincars.com/make/mercedes-benz-cls-450#complaint-1930336 Mon, 25 Sep 2023 00:00:00 GMT While driving in traffic, a warning box appeared indicating a problem with the 48volt charging system.

No nail or puncture was discovered but a hairline crack in the rear wheel. The tire shop manager advised me to call the dealership and ask the part to be replaced as this is a very low mileage vehicle.
