Customer Question
Check engine light came...

Check engine light came on. The "low tire" light STAYS on. I had to replace the gas cap and now the "Loose gas cap" light is on all the time. The dash is practically LIT UP all the time.

Mechanic's Assistant: Does the light stay on, or does it blink?

Staqys on

Mechanic's Assistant: What is the model/year of your Jeep?

2011 Grand Cherokee

Mechanic's Assistant: Are you fixing your Grand Cherokee yourself? What have you tried so far?

I have taken it into numerous shops and they say its a computer issue. I have already had to have some sort of switch replaced in the steering column so that the cruise control worked consistently. The electrical system in this car seems whacked. It has been like this off and on since I bought it used in 2012. I can't have it in the shop for days because I need it for work.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Just that there have been numerous reports from other consumers of this make/model that are all the same story.

Jeep Mechanic: Dan, Technician replied 8 months ago

I'd start by replacing the gas cap if that doesn't help the most likely cause is a failing Evaporative System Integrity Monitor (ESIM) Assembly​ which is common on this vehicle. It is about a $150-$200 repair at a shop. The low tire pressure sensor light usually means one of the low tire pressure sensors are failing or tire pressure is low so start by checking tire pressure. To have tire pressure sensor replaced is around $150 at a shop. Neither of these things will cause performance problems or lead to other problems. Let me know if you have questions, thanks.
