Teana horn sometimes works and sometimes doesn't, the reasons may include loose horn plug terminals, burnt horn relay contacts, poor contact at the steering wheel horn switch, etc. Below are detailed introductions about the Teana: 1. Overview: The Teana is a mid-to-high-end luxury sedan with a minimalist interior design, featuring a dark upper and light lower color scheme. The seats are made of three-layer cushioning material and have newly upgraded 3D side support. It offers both touch and voice interaction methods, enabling full-time navigation, online entertainment, online payment, and other functions. 2. Powertrain: It is equipped with a 2.0L naturally aspirated engine and a 2.0T variable compression ratio turbocharged engine. The 2.0L naturally aspirated engine has a maximum output power of 117kW. The 2.0T variable compression ratio turbocharged engine has a maximum output power of 185kW, paired with a CVT transmission. 3. Others: The new Teana adopts Nissan's latest family-style exterior design, incorporating Infiniti's dynamic design elements into the body lines, giving the vehicle a strong sense of fashion and sportiness.
My Nissan Teana has been running for over five years, and recently the horn keeps working intermittently, which is really annoying. Especially on rainy days or after car washes, the horn often fails to sound. I suspect it's an issue with the contact points on the steering wheel buttons—water seepage causing oxidation and rust, leading to intermittent contact. I tried opening it up myself and found the wiring harness connector a bit loose; a light touch would connect it, but letting go would make it fail again. A friend at the auto repair shop mentioned that common issues like this in the Teana also include aging electromagnetic coils inside the horn or poor contact after a fuse blows. The fuse is in the small box in the engine bay, which is easy to check, but don’t tamper with it if you’re unsure. In short, don’t overlook such a small issue—if the horn fails in an emergency, it could lead to an accident. Safety first. I recommend regularly checking these parts or directly replacing them to avoid risks.
