Which DeVille years have the most problems?
Complaint volume by model year. Raw NHTSA totals, not adjusted for sales volume or time on the road, so older and higher-selling years accumulate more. Every year links to its full breakdown.
Sentiment is bifurcated by generation. For classic models (1950s-1970s), sentiment is overwhelmingly positive, characterized by nostalgic appreciation for their iconic styling, immense size, powerful V8 engines (notably the 472 and 500 cubic inch motors), and
Northstar V8 Head Gasket Failure: Catastrophic failure leading to coolant loss, overheating, and engine damage. Very frequent in pre-2004 models. Frequency: very frequent.
Northstar V8 Oil Leaks: Persistent leaks from multiple engine seals (e.g., front cover, oil pan, rear main seal). Frequency: very frequent.
Engine Mount Failure (Front): Common failure leading to engine movement, clunking noises during shifts, and driveline vibration. Specifically noted on post-2000 models without torque struts. Frequency: recurrent.
Transmission Issues: Delayed engagement ("takes a few seconds to start going forward"), slipping, failure to shift into higher gears (e.g., 4th), leading to overheating and fluid burning. Frequency: recurrent.
High Repair Costs: Parts and labor costs are described as extremely high, with one report noting costs in a non-U.S. market can be "up to 700% more" than for a mainstream Japanese car. Frequency: recurrent.
