What Are the Common Problems With the Kia K5 and Nissan Altima?
Fire, steering, and braking reports set the Altima apart. Flames start under the steering wheel and near the battery, tie rods come apart during turns, and automatic emergency braking stops cars on the highway. Electrical, service brake, and steering complaints are all tied to crashes. The K5 has no such crash-linked trouble in steering or service brakes. Its reports center on a fuel tank that swells and lifts the back seat, hard shifts on the first cold drive, lights cutting out while driving, trim falling off at speed, and sunroof glass that shatters. K5 transmission trouble shows up early, within the first 3,000 miles.

Kia K5 vs Nissan Altima: Common Questions
- Is the Nissan Altima more reliable than the KIA K5?
- Slightly, yes. Both stand good on reliability, but Altima owners filed 1.6 complaints per 10,000 sold, against 10.2 for the K5. Recall counts are equal at 20 each. The Altima's lead is narrow because some of its complaints, such as fires and tie rod failures, are serious.
- Which has more recalls, the Altima or the K5?
- They are tied at 20 recalls each in federal recall records. The Altima's count spans nine model years, 2018 to 2026, while the K5's spans six, 2021 to 2026. So the K5 has collected the same number in less time, which matters when you check a specific VIN.
- Which model years of the KIA K5 should I avoid?
- Avoid 2021 and 2022, the weakest K5 years. Owners reported fuel tanks swelling with a loud bang, hard shifts on cold starts, and lights cutting out while driving. Several fuel tank cases left cars undrivable for weeks. If you buy one, confirm recall work was completed.
- What are the most serious Altima problems?
- Fire, steering, and braking reports stand out. Fires started under the steering wheel, in the dashboard, and near the battery. Tie rods came apart during turns and left cars unsteerable. Automatic emergency braking sometimes stopped cars on the highway with nothing ahead. Avoid 2019 and 2020, the weakest years.
