5 Worst Vehicles of 2020

In 2020, FIXD analyzed over 18 million vehicles. Through the FIXD OBD2 scanner and app, we were able to detect and decode thousands of engine codes and help drivers get back on the road stress-free. Here are the 5 vehicles that had the most OBD2 codes in 2020.

The Fixd scanner is awesome! It works just like the pros. I bought one and I’ve used it on all my vehicles at the house and some people who work on vehicles have even borrowed it from me! My name is Shannon Stephens I’m a nobody and I’m telling you right now this product works!

This is really good information specially if someone is looking to buy a used car. Any issues with MDXs?

There was nothing there for a 96 Cadillac Deville.

Unfortunately, Bob, not all vehicles have an OBD-II (OBD2) port. FIXD works on gas-powered (including hybrid) vehicles built after 1996 and diesels built after 2008 with an OBD2 port. To check your vehicle’s compatibility, visit our site: https://bit.ly/FIXDcompatibilitychecker

AWSOME tool, bang on diagnostics! It caught what could have been a catastrophe and saved me from losing my engine completely. It caught it immediately and saved me thousands, it ended up costing me $800. All for $20…i had just gotten it in the mail and plugged it in that day. I can’t thank you enough FIXED. It can’t catch everything, but it does catch the big stuff.

I drive a 2000 Tundra and the check engine light comes almost every refill of gas purge issue recommended a new gas cap which didn’t stop it

I think this is a great idea to give feedback on vehicle reliability, but I question the rigor of your approach. The supposed worst vehicle, the Ford F250, by your own data has a vehicle with over 1,000, 000 miles of usage! The more a vehicle is used, the more possibility of failure. How is usage, length of service, and driving conditions factored into your rankings! PS – I don’t even own a Ford 🙂

Good point Eric. The basic maintenance of the vehicles plays a big factor as well. My 2012 Town & Country is often cited as a money pit but I diligently change fluids as recommended and drive it sensibly and I have no drive train issues at over 90,000. Brake issues are another story unfortunately.

Maybe the next list should include codes that are more detrimental to a cars performance, rather than common fault codes that don’t necessarily affect performance.

Hi all, just wondering if i sell my present vehicle can i reset my FIXD for the new vehical?

FIXD

February 24, 2021

Hey Ken, no need to reset. Just plug the FIXD Sensor into your new vehicle and hit “Tap to Scan” on the free FIXD App to add your new vehicle to the app.

You can even use one sensor for all your vehicles, or connect multiple FIXD Sensors to your phone to remotely monitor the health of your entire fleet of vehicles and know when it’s time to schedule service – even if you’re hundreds of miles away if you would like! You can manage all your vehicles in the “My Garage” section of the app (its symbol is three cars in the top left corner of the app).

Hope that helps! Happy and safe driving 🙂

My wife has a 2011 HHR and the code is p0011,p0012 which has to do with the timing camshaft sensors and hydraulic sensors changed everything twice,can’t change timing and the engine light still comes on with the same codes.
