I purchased a 2007 Jeep Grand Cherokee Laredo at a large dealership on Tuesday. Leaving the lot I got a check engine light and the tire pressure warning light. Took it back and service dept reset the code. The dealership replaced the throttle body when they serviced it on trade in according to Carfax.
Drove 5 miles home and lights came on again. Called and was told to bring it the next morning. I took it back and after 4 1/2 hours they told me to come back the next day because they ordered the wrong parts.
Went back on Thursday and they replaced 4 TPMS sensors and the solenoid. Total cost of $1300 no charge to me. Drove 4-5 miles and parked, Got back in about an hour later and within one mile the lights came on.
Took it back in to the dealership on Friday and they reset the code again and test drove it “up to 50 mph” and no lights. I left again and drove about 10 miles and the lights on.
So after replacing the throttle body and solenoid any ideas? The dealership is not happy and I won’t find out if they will do anything else until Monday. I’m not sure what to look at next so anything from you would be appreciated.
