Q: Jump starting

The most likely cause of this is a battery with a failed cell, alternator, battery cable or the AC compressor itself. If the charging system has a fault, it will not be able to support all of the car's systems,...

In order to shift out of park, the transmission module needs to see the engine idling and the brake pedal depressed. If one of these criteria is not met, then it will not let you shift out of park. There...

You definitely want to start by inspecting the front and rear wheel speed sensors; a failure in these circuits will result in several other problems. Begin by connecting a scanner to see if the Powertrain Control Module (PCM) is registering...

Hello, thank you for writing in. Code P0449 (https://www.yourmechanic.com/article/p0449-obd-ii-trouble-code-evaporative-emission-control-system-vent-valve-solenoid-circuit-malfunction-by-spencer-clayton) will set when the system sees that the position of the vent valve, and the voltage for its position, do not match. There could be a wiring problem, a faulty hose,...

Hi, thanks for writing in. I suspect your "upstream" sensor is the primary problem, and should be replaced. The downstream sensor you did replace is really measuring whether the catalytic converter (the main cat, not the pre-cat) did the job...

P0717 is derived from engine speed (usually sensor counting flywheel revolutions), not necessarily sensor in the transmission, and not vehicle speed sensor - different sensor. The engine speed sensor may have failed - independent of cruise control symptoms. Check cruise...

The oil leak itself may not necessarily ruin the CV axle, however if the oil leak progresses to a point where the CV joint lacks the proper amount of oil to sufficiently lubricate it, the lack of lubrication can cause...

It sounds like you have 4 issues: Coolant leak (https://www.yourmechanic.com/services/coolant-is-leaking-inspection) Possible issue with the water pump (https://www.yourmechanic.com/services/water-pump-replacement) An unexplained, but transitory noise (https://www.yourmechanic.com/services/car-is-making-a-noise-inspection) HVAC faults (https://www.yourmechanic.com/services/heater-is-not-working-inspection). The coolant leak is the most important one to fix first because a coolant...

These types of noises can generally come from a faulted cv axle or badly worn wheel bearing on the vehicle. A cv axle with torn grease boots may make more noise during tight cornering and a worn wheel bearing will...
