What causes the BYD Surui's lack of acceleration power?
3 Answers
BYD Surui's lack of acceleration power is mainly due to engine lubrication and system malfunctions. Below are the related causes and solutions: 1. Engine: Engine lubrication and system malfunctions, engine overheating. Solution: Seek professional repair technicians for maintenance. 2. Intake pipe: Air leakage in the intake pipe causing excessively lean air-fuel mixture. Solution: Repair the intake pipe. 3. Ignition system: Weak high-voltage spark due to faulty spark plugs, igniters, or high-voltage wires. Solution: Replace spark plugs and igniters. 4. Exhaust system: Poor operation of the exhaust gas recirculation system. Solution: Have professional technicians repair the exhaust gas recirculation system.
When I drive my BYD Surui, the acceleration feels sluggish, like the car is dragging its feet, without the previous sense of push-back. It might be related to the fuel system. The fuel pump could be aging or clogged, causing insufficient fuel delivery, leaving the engine underpowered. The spark plugs, which have been used for two or three years, probably need replacing—weak ignition naturally leads to poor performance. If the air filter is clogged with dust, insufficient air intake can cause incomplete combustion, especially noticeable during traffic jams. If the transmission fluid is low or degraded, gear shifts may feel sluggish, like climbing a hill. Also, consider fuel quality—using low-grade fuel with impurities can dull acceleration. Here are some simple checks: replace the air filter first, try higher-octane fuel, and regular maintenance can boost performance. Additionally, a faulty electronic throttle position sensor might limit throttle response, so it's advisable to visit a 4S shop for a computer scan. Don’t let small issues escalate—safety first.
Acceleration weakness is common in BYD Suri. Having driven similar models, check these key points: Engine oil passage blockage or fuel injector issues can cause improper air-fuel mixture ratio, resulting in weak engine output; Worn transmission clutch or torque converter problems affect power delivery; Low tire pressure increases rolling resistance, hindering acceleration. Replace spark plugs when their lifespan ends, otherwise weak ignition can cause misfires. Regular oil and filter changes also prevent issues. ECU faults sometimes misjudge power demand, limiting speed. Recommend monthly self-checks of oil pressure and tire pressure for quick resolution. Long-term neglect can damage the engine and affect high-speed stability. Don't forget to inspect the fuel filter - replace if clogged. Visit professional shops for comprehensive diagnostics to save time and effort.
