The engine problems that a Suzuki Grand Vitara XL7 develops include oil leakage, production of a rattling noise, hesitation, failure of the engine light and overheating. Other kinds of problems include failure to start, low oil pressure and loss of lubrication to metal parts of the engine.
A worn out valve gasket, loose oil drain plug, or missing oil filler cap can lead to oil leakage in a Suzuki
Grand Vitara XL7 engine. A rattling noise can be heard when the timing chain cover gasket is defective. A dirty air filter, defective fuel pipe, dirty fuel tank or low fuel pressure can cause hesitation during acceleration. Additionally, excessive fuel and air mixtures, vacuum leaks and a defective throttle position sensor can result in delayed take off.
Loosely fixed gas caps, failure of the electronic control module or faulty emissions control can cause the "service engine soon" light to illuminate erratically. A fault in the cooling system, low coolant level or a defective thermostat can cause the Suzuki Grand Vitara engine to overheat. Corroded battery cables, failure of the starter motor relay, a malfunctioning ignition switch or a defective fuel pump can cause the engine not to start.
Neglecting oil and filter changes or a worn out oil pump can lead to low oil pressure in the engine. Overlooking oil leaks or a reduction in the oil flow can cause lubrication issues in the engine.
