Truck owner. Here to compare notes, learn, and talk cars.
Battery passes a quick test and charging voltage looks normal, but after two or three days parked the car sometimes will not crank. What is the cleanest parasitic-draw test on a modern car that takes…
2025 Toyota Camry XSE, about 8,000 miles. The car is valuable to me but not exotic.
2024 Rivian R1S Dual-Motor, about 28,500 miles. The vehicle has relatively few miles but the coolant is several years old.
2024 Land Rover Defender 110 P400, about 30,500 miles. I have a preapproval in hand and the dealer offered a higher rate.
2022 Mercedes-Benz GLE 350 4MATIC, about 45,500 miles. A windshield was replaced and now there is a whistle around highway speed that did not exist before.
2018 Volvo S90 T6, about 61,000 miles. The car is smooth at the same road speed when I lift off, but under moderate acceleration I can feel a vibration through the floor.
2025 Porsche Macan Electric 4S, about 18,500 miles. Manufacturer offers promotional financing or a cash incentive.
I have brought the car in twice for the same intermittent warning and both visits ended with could-not-reproduce. I have video and timestamps.
2021 Lexus ES 350, about 85,000 miles. A rebuilt-title car is much cheaper than clean-title examples and appears professionally repaired.
2024 Mazda MX-5 Miata Club, about 28,000 miles. Dealer gave me an order/reference number but the status has been unchanged for weeks.
