The picture
Is the Mercury Cougar or Chevrolet Silverado more reliable?
A plain-English read on what the NHTSA record says about living with each vehicle.
Mercury Cougar
The Mercury Cougar is a sporty coupe that, based on owner complaints, can be a headache to own. Over three years, it averaged 135 complaints per year, with fuel system and gasoline issues dominating the list. Owners report stalling at speed, hesitation after fuel pump recalls, and even engine fires. With 11 recalls and 35 injuries reported, it's a vehicle that demands careful inspection before purchase.
Chevrolet Silverado
The Chevrolet Silverado is a full-size pickup with a much higher complaint volume—averaging 823 per year over a decade. Engine and power train problems are most common, including engine shutdowns, transmission failures, and brake loss. Despite 101 recalls and 160 injuries, the sheer number of trucks on the road means many owners may not experience severe issues, but the reported failures can be dangerous.

Owners frequently report stalling while driving, especially at highway speeds, and hesitation even after fuel pump recalls. This can leave you stranded or cause a crash if it happens in traffic.
Complaints about gasoline often overlap with fuel system issues, including intermittent stalling and restart problems. The recurring nature suggests a persistent design flaw that may not be fully fixed by recalls.
There are reports of electrical fires, with one owner stating their car caught fire while parked. This is a serious safety concern that could total the vehicle or endanger lives.
Owners report engine knocking, sudden failure, and smoking, sometimes with no warning lights. One owner had to replace the engine at 65,000 miles, indicating potential premature wear.
“AFTER ALL THE PROBLEMS WITH MY 2001 COUGAR I WISH I WOULD HAVE MADE A BETTER CHOICE IN WHAT VEHICLE I BOUGHT. THE ONE RECALL THAT THEY HAD ON THE FUEL PUMP I HAD TO HAVE THAT REPLACED, BUT I AM NOT SURE THEY REALLY FIXED IT BECAUSE IT STILL HESITATED WHEN I A…”

Complaints include engine shutdowns while driving, diesel particulate filter soot accumulation, and rough running. These can cause loss of power and require costly repairs, especially on newer models.
Owners report transmissions suddenly shifting into neutral, engine stalling, and other drivetrain failures. This can happen at low speeds or in parking lots, increasing crash risk.
Electrical issues often manifest as brake problems, with owners describing a sudden loss of braking effectiveness and messages like 'Return to Neutral.' This is a critical safety defect.
Brake complaints include a firm pedal with reduced stopping power and complete brake failure. Given the weight of the Silverado, brake loss is extremely dangerous.
“I purchased the 2026 Chevrolet Silverado with a 6.2L motor "new" from the dealer with 5700 miles on XXX. Roughly a month and 2500 miles later, my family and I were in the vehicle, 750 miles from home, returning from a vacation to [XXX] from the [XXX]/[XXX] ar…”

Buyer analysis
Mercury Cougar or Chevrolet Silverado: which should you buy?
The Mercury Cougar has far fewer complaints per year (135 vs. 823), but its issues are concentrated in fuel and electrical systems that can cause stalling and fires. The Silverado's higher volume reflects its popularity, but its engine, transmission, and brake failures are also severe. In practice, the Cougar may have fewer overall problems, but both vehicles have red flags that require thorough inspection.
Key differences
- The Cougar's top complaints are fuel system and gasoline issues, often causing stalling; the Silverado's are engine and power train, with shutdowns and transmission failures.
- The Cougar has 11 recalls over 3 years, while the Silverado has 101 over 10 years, indicating a much higher recall rate for the truck.
- Electrical problems in the Cougar include fires, whereas in the Silverado they often involve brake loss and unintended acceleration symptoms.
- The Cougar averages 135 complaints per year; the Silverado averages 823, but the Silverado's larger production volume means the rate per vehicle may be lower.
- Check for fuel pump recall completion and test-drive for hesitation or stalling, especially at highway speeds.
- Inspect electrical wiring and battery connections for signs of overheating or fire damage, as some owners reported fires.
- Test-drive for sudden engine shutdowns or transmission slipping, and check for stored diagnostic trouble codes related to the engine or transmission.
- Verify that brake recalls are performed and test braking from various speeds; some owners reported a firm pedal with reduced stopping power.
Before you buy
- Obtain a full vehicle history report and confirm all recalls have been remedied.
- Have a trusted mechanic perform a pre-purchase inspection focusing on the Cougar's fuel and electrical systems or the Silverado's engine, transmission, and brakes.
- During the test drive, pay attention to any hesitation, stalling, or unusual noises, and test all electrical components.
- Ask the seller for maintenance records, especially for fuel pump or brake repairs.
- Check for open recalls by VIN with a dealership and ensure they are addressed before purchase.
