Drain hole issue

Water is making its way into the car after a heavy rain. It looks like a drain hole issue.
Experienced mechanics share their insights in answering this question :
Mazda has two service bulletins concerning the soft top drains possibly clogging up leading to leaks that develop in the floorboard. The filter screens at the drain entrance may need to be cleaned and the drain tube itself may need to removed and cleaned or replaced with an updated drain.

Mazda also has two other service bulletins for possible sources for soft top leaks at the windshield area also. The vehicle may need to be water tested in specific areas of the top using a water hose to determine the source of the water intrusion and then that source where the water intrudes needs to be repaired.

You may want to contact your dealer and see if they are willing to cover either of these repairs.

Pour one-half cup table salt down the drain, followed by boiling water. Or try a cup of baking soda and a cup of vinegar—let it bubble, wait 15 minutes, then pour boiling water down the drain.

The most common location for drain holes is at the bottom of the doors. Since rainwater can seep in past the door seal, the drain holes ensure that water will not collect under the seal and go unnoticed. Vehicles often incorporate drain holes in other areas as well.
All vehicles have drain holes in the bottom of the door panels. Some vehicles will drain more than others.
Car doors are designed with drains that allow the water to drip harmlessly onto the road as you drive, but if these drains become clogged, rain and snowmelt can collect inside the doors and eventually leak into the interior. To fix this problem, you`ll want to make sure to keep your door drains free of road debris.

1.5`s are a bit softer and have more comfortable ride, and 2.0 can come with dealer fit optional sports suspension package. So all 1.5`s are good, ND1 or 2, but for 2.0 get an ND2..! Whenever I`ve browsed MX5s, the main difference is that 1.5s are 5 speed, 2.0s are 6 speed.

ANSWER : Hi there. It’s quite possible that you have one of two things causing the drain to the battery. First, you have a bad ground somewhere in the main relay or fuse box or an exposed wire somewhere that is not allowing the circuit to complete from the alternator to the battery. This can cause a battery draining issue as you’re describing, but it could also be one of multiple other electrical problems. The best way to pinpoint the exact source is to have a professional mobile mechanic come to your location and complete a battery will not hold a charge inspection.

Over filled oil gears shift late on turns. Will draining excess resolve issue?
ANSWER : Hello, thank you for writing in. There are several things that can happen when you overfill the oil in your engine. The damages can range from high oil pressures (and stress on the system), to complete engine failure. With that said, you may have partially locked up the engine, bent a rod or valve, blown oil into the combustion chambers, or caused the oil pump to fail. The only real way to tell is to drain the oil and see what kind of condition it runs in after the oil level is brought to spec. If you are hearing new noises, it is running funny, or there are any changes, have it inspected by a professional. For any further help resolving the issue, contact our service department to schedule an appointment.

Startup issues after the battery drain
ANSWER : The starter may have been damaged while the battery was low on charge and it worked too hard trying to turn the engine. I would take the dealer advice and replace the starter first.

I would hold the dealer to the diagnosis if you still have the issue after they put the starter in and the anti-theft system is the problem. Have them check the anti-theft system first then replace the starter. The antitheft would show on the dash when you try and crank if it was the problem, however.

My 2011 Acadia is leaking engine oil. Above the drain plug is wet- it’s dripping off the drain plug
ANSWER : Oil leaking above. the oil pan can be coming from a number of places depending on how far above the pan, the oil is leaking from. The oil pan gasket, timing cover gasket/seal, or even the oil pressure switch are just a few places that oil can be leaking from. If the vehicle is still covered under the powertrain warranty, some instances of oil/fluid leaks, may be covered at no charge to you. Consult your warranty information and/or your dealer’s service department for more information on that.

If it is not covered, then a certified technician can look into the source of the oil leak visually, or by performing a dye test. A special dye that glows a florescent color under special lighting can be added to the engine oil. After the engine is run for a bit, the dye will come out with any leaking oil and show under the black light.

Car jerks when accelerating in reverse & makes grinding noise. Is this a transmission or computer issue?
ANSWER : Hi there. Typically when you hear a grinding noise when you move forward or in reverse it’s usually an indication of a gear fault either in the transmission or another driveline component. If this occurs only when in reverse, it’s likely a damaged reverse gear. It is also possible that it’s a hydraulic fluid issue not supplying enough lubrication or pressure inside the lines to fully open the gear. I would recommend having a professional mechanic come to your location and complete a car is hard to shift inspection, so they can diagnose the source of your issue and recommend repairs that should resolve this problem.

Battery drained and car key couldn’t open car door.
ANSWER : Hi there. The battery is draining for a parasitic load applied to the battery over night. This will drain the battery to needing a charge or needing a replacement. If the alarm was installed and it was for a newer vehicle, as long as the wiring is correctly installed into the vehicle, the year of the alarm should not matter. The alarm was probably installed on the wrong circuit causing the other circuit to have a load applied to it when the key is turned off. I recommend disabling the alarm and see if the battery does not discharge. If so, then hook up the alarm to a different circuit isolating it from any other circuits. If you need further assistance with your battery draining, then seek out a professional, such as one from Your Mechanic, to help you.
