What Are the Common Problems With the Kia Carnival and Lexus TX?
Crash-linked reports separate these two. The TX has them in air bags (2) and the electrical system (1), including a power liftgate that closed on people's heads. Its largest group is air bags, where curtain air bag recall repairs stall for months on missing parts. The Carnival lists no crash-linked area. Its biggest issue is electrical: a battery that drains overnight, repeated jump starts, and lost key and app access. Hybrid vans also stop accelerating near 31 mph, mostly on cold mornings, and dealers often cannot reproduce it. Power sliding doors can close hard and react late to obstacles.
