The most consistent pattern in 2019 BMW 430i complaints centers on the engine. Owners frequently report coolant leaks leading to overheating, with the dashboard displaying overheating warnings before the engine stalls. Several owners describe being towed after the engine stopped running, and at least one reports being told a full engine replacement was needed after oil pressure warnings appeared alongside the overheating alert. Airbag complaints are the second most reported area, with owners describing situations where airbags did not deploy during a collision, as well as fault codes related to the restraint system going undetected during pre-sale inspections due to outdated software. A smaller cluster of electrical complaints includes convertible top failure tied to water pooling inside the rear window panel, which owners say damages the window motor and regulator and then disables the top.
