Q: Battery completely flat

Hello! I suggest having the vehicle inspected by another technician to get a second opinion. Usually when a Check Engine Light is on, the vehicle will have some type of issue. Rarely will a Check Engine Light illuminate when nothing...

There are several issues that could possibly cause this issue. A bad connection (https://www.yourmechanic.com/services/electric-problems-inspection), a failed starter (https://www.yourmechanic.com/services/starter-replacement) (or starter solenoid), a bad relay (https://www.yourmechanic.com/services/starter-relay-replacement), or any number of other possibilities. It would be best to have a certified mechanic...

Hi there, thanks for writing in. It's very possible that the crank position sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-crankshaft-position-sensor) is either sending faulty data or is broken and needs to be replaced. The car is shutting off automatically as a safety precaution due low...

Hello. This may be a sign of a faulty transmission control solenoid (https://www.yourmechanic.com/services/downshift-solenoid-replacement). Modern automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car's computer activates a transmission solenoid, which directs transmission...

Hi there. Typically a bad motor mount will make a clunking sounds as the vehicle begins to accelerate or decelerate. The grinding sound while acceleration and turning is a common symptom of a bad or failing wheel bearing (https://www.yourmechanic.com/article/symptoms-of-bad-or-failing-wheel-bearings) as...

Hello - this message (P0335 (https://www.yourmechanic.com/article/p0335-obd-ii-trouble-code-crankshaft-position-sensor-a-circuit-malfunction-by-spencer-clayton)) indicates that the crankshaft position sensor (https://www.yourmechanic.com/services/crankshaft-position-sensor-replacement) is failing, causing the "cutting off" you have already noticed. It is located on the bottom of the engine/transmission interface (drivers side of the vehicle). To avoid...

Hi there. This is one of those problems that is either easily solved or impossible to locate. In most cases, the warning chime function is linked in conjunction with the warning light itself. So, when the seat belt lamp illuminates,...

A more likely explanation is the engine is not "quickly" responding to the increased load placed on it when the a/c turns on, although apparently the idle does smooth out after a short delay. If the motor mounts were a...

There are many causes of hard starting but illustrative ones are a faulty engine coolant temperature switch (sensor), worn spark plugs, inadequate fuel delivery or pressure (e.g., clogged fuel filter), dirty fuel injectors, contaminated or old gasoline, malfunctioning idle air...
