Known problems on the Tesla Model S 75D
Touchscreen lag, reboots or black screen
Costly if missed
2012–2018 · ev · Electrical
What to look for: Force a screen reboot with both scroll wheels and watch for a slow restart, lag, a blank map or a black screen.
Why it matters: A dead or dying MCU1 can take the reversing camera, demist, climate and charging settings down with it, and leaves the car hard to drive comfortably until it is fixed. Tesla's free-replacement window is tied to the car's age and odometer, not to who owns it, so a car near or past 8 years / 160,000 km may already be outside cover and facing a four-figure repair.
What to look for: On the test drive with the radio off, listen for a whine or grinding from the rear that rises with speed.
Why it matters: A failing rear drive unit progresses from noise to vibration to a loss of drive, and a reconditioned replacement is one of the costliest single repairs on the car. Buying a car with early symptoms, or one that has already had a unit replaced outside Tesla's warranty, can mean a large bill soon after purchase.
What to look for: Check the car sits level on arrival, then raise and lower it from the screen and watch each corner move evenly.
Why it matters: A sagging corner or a failing compressor only gets worse, and an independent shop repair runs well into four figures per corner. The fault can start as something subtle - slow levelling, one corner a little low overnight - so a car that looks fine standing still can already be heading for a bump-stop ride, and a height sensor fault can mimic a leak, so finding which one it is avoids paying to fix the wrong part.
What to look for: Look along all window chrome and the trim strips under the doors for staining, bubbling or lifted edges.
Why it matters: Stained or bubbling trim is cosmetic but spreads over time and is not a Tesla warranty item, so a buyer should expect to either live with it, replace the mouldings, or wrap them.
