This is my second XC90. The first one is always accurate on how many miles it say I can travel on the gas I have in my tank. This second one for example displayed that I had 155miles to go my gas and my GPS displayed my destination to be 54miles. Which means I should have enough gas to and fro. I had to get more gas by the time I was coming back. Someone please advice. What do I have to fix?

Driving a 2005 Volvo XC90,(very great SUV. Never had a regret). I recently av problem with the windshield washer. When I pull the lever on the steering wheel to spray water on the front or the back shield the water sprays on the headlight instead(b/cos there'ar small outlets @ the base of the headlights 4 water to spray on the headlight if they'ar dirty). Already cleaned my headlights several times and reviewed my owners manual, and could not find any helpful hint. Spent time touching and trying everything I could in the vehicle to no effect. I need someones help urgently pls. I need a solution b/4 winter snow starts.

I really need to know to be done. Always cared of codes when they show up it is always a lot of money at the shop. What will have to be changed. Will it be expensive? Please help with honest answers. Thanks

Vehicle is 1997 Mazda 626 V6. Drives good, no sign of faults at all. CEL scan returns above 3 codes. Really scared these will drain my savings. What are these? Someone pls help with detailed explanations.

I have this code - Catalyst efficiency below threshold(bank 1). If I change the O2 sensors, will it fix the problem or I really have to change the catalyst converter. changing the converter can be pretty expensive. Help needed.
