I purchased a used 2017 Jeep Grand Cherokee. I only drove the jeep for 2 days and the check engine light came on. On the way to the mechanic the jeep overheated. I was left on the side of a busy road and put in a dangerous situation. When I made it my mechanic shop, the mechanic explained the 3.6 engine has repeat issues with overheating! I now have a vehicle I cannot drive. Why has there not been a recall if this is an issue for many with this engine?

I have replaced the water pump three times costing me close to $1000.00. No warning light has came on only the smell when it is leaking that my fiancé recognizes. So in this case do I have to wait until it starts to overheat and I am stranded on the side of the road? Why am I replacing an obvious faulty part? I also know that I am not the only jeep owner within the year of mine that has had this problem that Jeep doesn’t recognize? If needed I can provide copies of my receipts and dealership paperwork. Also why are the new water pumps protected with a warranty? Each water pump I had installed could have defects.

Purchased the car brand new back in 2017. In 2020, while driving normally, the car loss power and would not accelerate and started to have rough idles then auto stop/start came on followed by check engine. Brought it to the mechanic for diagnose and told me that there is a misfire on cylinder 2 and VVT sensor needs to be replaced. Brought it to the dealer and they fixed the issue. Two years after (present) at 100K miles, The car started to have the same issue. Yes it was high mileage but it was driven responsibly along with timely and proper maintenance from the dealer. The car started to have rough starts and white smoke on cold start. And on August 26, 2022 the car would not start. Got it towed to the dealer and told me that it has a bad starter. I was quoted for almost $2000. Once they got it to start after 3 weeks, they noticed the white smoke, the diagnosed it and told me that It has a blown head gasket. The car was driven responsibly and never overheated. They quoted me for $4600 just for the head gasket replacement. They still have my car and haven't decided what to do as it is very frustrating to think that in a short period of time, the car just gave up on us and will leave a huge hole in our pocket. It is our family car and now realized that Jeep (FCA/Stellantis) don't care about their customers because I have seen the same exact reports like mine. I don't get why it's not a recall yet. Please! Make this a recall because it's leaving families to have more financial hardship because of faulty engines that Jeep brand created.

Oil cooler failure, causing oil to go into the coolant system and mix. Completely draining all oil from my engine and leaking from and unknow seal in the coolant system. At no time did my vehicle warn me of the issue. No check engine light, no overheating light and I drove my vehicle from home to work which is about 60 miles (salisbury, md to lewes, de) . This left me stranded at work and unknow damage to my vehicle because of no "caution" lights. The leaking oil could have caused an engine fire with all the oil draining out and into the coolant system and over heating my engine.

Dec 2020: in a parking lot, the engine would turn over but not start. My mechanic bypassed the built-in fuel pump relay in the tipm but the engine would not start. Towed to campbell jeep, benton ar & they diagnosed that both fuel pumps were bad. Dealer could not give reason both pumps went out but I suspect that statement is untrue given that my research shows that the tipms have been a known problem since 2010. Cost of the repair was $1,871.96 3/23/21: at home, the jeep would turn over but not start as before in dec 2020. Sat three hours then started. Continues to start but after research I suspect that the built-in fuel relay in the tipm is bad but allows for intermittent starting. I corresponded with an engineer in maryland that has devised fuel relay bypasses for chrysler's defective tipms. I am purchasing a bypass from him for $36. Were the fuel pumps bad in dec 2020 or would this $36 part have repaired it? In my research, it has also been reported that the defective tipm may cause the fuel pumps to continue running after the engine is turned off. Did the fuel pumps overheat because of that or did the dealership misdiagnose bad fuel pumps and charge me for work that did not need to be done? I suspect that chrysler's known defective tipms have caused chrysler vehicle owners a great deal of money. I also suspect that chrysler's continued use of the known defective tipms also pose a potential physical danger to the driver & passengers if & when the engine stops in traffic or when they are stranded.

The compressor for the air suspension overheats causing a clunking noise from the left driver side of the engine compartment and is the suspension to not work at all leaving you in park mode exit/enter and you get a flash code of service air suspension immediately .this is very similar to some of the problems they had with 2011 and 2012 models of jeep grand cherokee they need to offer a standard conversion kit fix to fix these jeep because the air suspension is not perfected and very dangerous
