The most-complained-about systems on each vehicle — what fails, and what owners say in their own words.
Mercury Mariner

- 02POWER TRAIN233
- 03VEHICLE SPEED CONTROL182
- 04ENGINE164
- 05FUEL/PROPULSION SYSTEM109
Owners report the steering wheel becoming difficult to turn, often traced to steering column or pump failures. This can happen at speed and make the vehicle hard to control, posing a serious safety risk.
Transmission problems are common, with reports of gears not shifting, loud noises, and violent shaking. These failures often occur around 42,000 miles and can leave the vehicle undrivable.
Complaints include gas pedal failures and sudden loss of power with the overdrive light blinking. This can cause the car to stall or lose speed unexpectedly, increasing crash risk.
Some owners experience a 'Stop Safely Now' warning, especially in hybrids, leading to immediate power loss and overheating. The engine and electric motor may shut down without warning, leaving you stranded.

Owners report intermittent issues like the ignition key getting stuck in Park and transmission hesitation or shuddering. These problems can be frustrating and may require dealer visits to diagnose.
Complaints include delayed throttle response when pressing the accelerator, with the car taking several seconds to move. This lag can be dangerous when merging or crossing traffic.
The electronic parking brake may fail to disengage, requiring a tow, and some owners hear clicking or vibrating noises from the ABS system. Brake issues can affect vehicle safety and lead to costly repairs.
Multiple systems like stability control, power steering, and blind spot monitoring can malfunction simultaneously. This can overwhelm the driver with warnings and reduce vehicle control.
“My 2023 Toyota Camry has developed an intermittent defect where the ignition key becomes stuck and cannot be removed even though the dashboard shows the vehicle is in Park. The only way to remove the key is to disconnect the vehicle's battery, which is not a…”

Buyer analysis
Mercury Mariner or Toyota Camry: which should you buy?
The Mercury Mariner has fewer complaints per year (186.4) than the Toyota Camry (205.6), but the Mariner's issues are more often severe, such as steering and transmission failures that can cause loss of control. The Camry's higher annual average and more crash-related reports (171 vs. 36) suggest a broader range of safety concerns. In practice, the Mariner may have fewer complaints but they tend to be more critical, while the Camry has more frequent but sometimes less catastrophic issues.
Key differences
- The Mariner's most common complaint is steering (559 reports), often involving sudden difficulty turning, while the Camry's top issue is power train (385 reports), including transmission hesitation and stuck ignition keys.
- The Camry has far more crash-related reports (171) and injuries (158) than the Mariner (36 crashes, 37 injuries), indicating a higher rate of incidents in the data.
- The Mariner has 22 recalls, including suspension and hybrid propulsion issues, while the Camry has 31 recalls, covering air bag sensors and seats.
- Owners of the Mariner frequently report transmission failure around 42,000 miles, whereas Camry owners describe intermittent electronic and brake problems that may be less predictable.
- During a test drive, check for any difficulty turning the steering wheel or unusual noises from the steering column, as these are common failure points.
- Ask for transmission service records and test for smooth shifting; listen for loud noises or shaking that could indicate imminent transmission failure.
- Test the ignition key removal in Park and check for any hesitation or shuddering during acceleration, which could signal power train issues.
- Verify that the electronic parking brake engages and disengages properly, and listen for clicking or vibrating noises from the brake pedal area.
Before you buy
- Obtain a full vehicle history report to check for open recalls and past repairs, especially for steering and transmission on the Mariner and power train and brakes on the Camry.
- Have a certified mechanic inspect the steering system and transmission on the Mariner, and the power train, brakes, and electrical systems on the Camry.
- During a test drive, pay attention to any warning lights, unusual noises, or changes in steering and braking feel.
- Ask the seller for maintenance records and confirm that all recall work has been completed.
- Consider a pre-purchase inspection by a dealer or independent shop familiar with the specific model's common issues.
